Digger for power tiller with his own hands

Vibrating tiller with my own hands

Practical experience, which is shared by farmers, shows that the use of vibrating potato digger provides 95% harvesting of potatoes, and the use of simple fan allows for the collection of up to 85. Other vegetables (onions, garlic, beets or carrots) can also be harvested with the vibratory digger, if they are grown in large areas.

Vibrating potato digger for a power tiller with their own hands can be made from improvised materials. You can use parts from an old car: front hub, gearbox from the rear axle, drive shaft.

The frame assembly diagram is described above. On the frame brackets are welded to mount the gearbox and mechanisms that will perform reciprocating motion, t. е. create vibrations in the machine. When working, the rotation of the shaft of the power tiller is transmitted through mechanisms (lever and connecting rod) to the vibrating table (screen). The rod, connected to the crank mechanism, performs oscillating movements. The ploughshare is attached to the lower part of the frame and the screen on hinges.

Depending on the design the cleaned tubers will roll off the vibrating table at the side of the processed strip or at the back of the potato spudger.

Plot, intended for potato harvesting, should be cleaned of the haulm and weeds before processing, otherwise they will be hammered under the grate and in the wheel mounts.

Homemade and factory-made potato harvester blueprints

For a small farm, to be convenient to harvest potatoes, you need to make a small device. It must be easy to use, and should be easy to hitch up to a single-axle tractor.

construction of a potato harvester: 1. welded frame, 2. knife, 3. conveyor, 4. pulley, 5. connecting rod, 6. pulley of the angular gearbox. 7. belt, 8. rack, 9. adapter, 10. support wheel, 11. spring tensioner.

In order to make the device in question, it is necessary to have:

  • Steel channel.
  • A coulter poured from a high quality metal alloy, at least 5 mm thick. You can use a circular saw to make it.
  • Metal angles in sizes 40 and 63 mm.
  • Steel rods. A minimum of 8 of these are needed to make the implement as shown in the photo.

To make a device for digging potatoes of the vibrating type requires, first of all, to make a frame. It should be easily docked, for example, with a mini tractor “Neva” or other modification.

In general, as shown in the video, such a device consists of the following units:

To design such a unit, it is required to make accurate calculations and according to them create drawings. Without following this rule, the process of making it with your own hands will be difficult.

How to make a vibrating potato tiller for a power tiller with your own hands

Vibrating potato digger is considered one of the most versatile devices of this type. The design of the unit allows you to install it on any power tiller or minitractor and use it on all types of soil.

Before proceeding to make a potato digger for a power tiller with your own hands, it is worth stocking up on the following materials:

  • metal rods;
  • a steel channel;
  • a section of steel;
  • coulter from 5 mm;
  • Metal corners (40 and 60 mm);
  • profile tube;

Before making a screen potato digger, you need to stock up on fasteners and bolts

Algorithm for the manufacture of a screen potato digger for a motoblock with their own hands:

  • First of all we need to construct the frame of the device. For this purpose it is necessary to saw the pipe into four parts. They should be 120 cm and 80 cm long in pairs.
  • The resulting sections should be welded in the shape of a rectangle.
  • Weld the crosspieces, they are mounted on a quarter of the base length.
  • Parallel to the crosspieces, install the blanks of the wheel mounts in the number of two pieces. You need to use 15 cm long pipes with a diameter of 3 cm.
  • Then you need to weld the vertical struts. At a distance of 5 mm from the edge of the frame, in the place where the crosspieces are located, fix a couple of 50 cm long plates.
  • At a distance of 20 cm, it is necessary to mount pieces of 4 cm in length. At a distance of 40 cm from them and install a third pair of 30 cm long struts.
  • Use a sheet of metal to assemble the frame. Its size should be 40 cm by 40 cm (thickness from 3 mm). Mount the first piece to the bottom of the strings. The second part (measuring 70 cm x 70 cm and 4 mm thick) should be welded to the first one and shaped with a sledgehammer into a cone.
  • A trellis made of rods is welded to the frame, and its ends must extend beyond the frame. The number of pieces can vary from 10 to 15 pieces, depending on the type of crops to be cultivated.
  • To reinforce the grid across it, two more pieces of rod are welded.
  • Install the wheels on the previously prepared mounts.

Potato digger with their own hands. equipment, materials, manufacturing procedure

Fast harvesting is not only important for farmers, but also for homesteaders. Digging potatoes in one or two days is especially important in cold, rainy autumn, when it’s difficult to choose a nice day to go to the fields. Speed up the work will help potato digger, with your own hands you can make a simple and effective unit, the performance is not inferior to the factory counterparts.

/ Potato diggers are used on loose and medium compacted soils. Machines for digging potatoes are different:

  • dimensions;
  • design features;
  • The width of the working strip;
  • requirements for clearing the field of weeds;
  • How to clean the tubers from the ground.

Masters make several types of potato diggers with their own hands. The most popular are fan and screen units. experienced masters make transporter and drum diggers for potatoes.

Model KVM-3

This model belongs to the vibration modular machines of the screen type, and differs in its design. Potato digger has a static knife and a shaker table, moving along a special elliptical lifting-pushing path. Blade is attached to the drive frame through the adapter, which provides additional vibration. Therefore, the machine can work on particularly heavy soils. The vibration shakes the ground a lot, the tubers are easily peeled, fall out to the surface. Universal vibrator mechanism allows you to work with power tillers, whose pulley is installed both on the left and on the right.

KVM-3 is aggregated with power tillers Neva, MT3, Salut, Zarya, Agat.

The modular vibratory potato harvester has the following features:

  • overall dimensions 900x670x560 mm;
  • weight 34 kg;
  • working width of 39 cm;
  • Working depth 20 cm;
  • productivity 0.1 ha/h.

The unit is inferior to KKM-1 in terms of efficiency of harvesting root crops, but its cost is lower.

Manufacturing process

Drawings of the potato harvester are made by analogy with schemes, which are easy to find on the Internet. When buying the power tiller the user manual is attached, where the dimensions and other parameters of the attachment (weight, digging depth) are specified. On the basis of these data, you can find the necessary information and on its basis make your own version of the machine for potatoes. This option seems to be very rational, since each motobloc has its own peculiarities.

The algorithm for creating the unit is as follows: a tube with a diameter of 45 mm is sawed into four parts. For example, it can be done in this way: two pieces of pipe of 1205 mm and two pieces of pipe of 805 mm. Then a rectangle is made on a level plane and the joints are welded together. Crosspieces are also welded that will serve as control rods. Then it is necessary to create vertical mounts. they will provide the installation of vertical rods, which are responsible for control.

The uprights, which must carry the vertical load, are then fastened. Crossbars are attached a short distance from the frame edge. The squares should be 35×35 mm and have a length of 50 cm. The bars are connected to one another by connectors.

Then you need to mount the shaft. Stainless steel sheets are used, the thickness of which should be 0.4 mm. The plates are welded together. After that comes the turn of the bars. they will implement the work of the “sifters”. Such machinery makes it possible to effectively remove a good crop of root crops in a minimum amount of time.

The standard design consists of the following elements:

  • metal frame (made of pipes or corners);
  • the plow blade;
  • is a device, which transports the product;
  • connection pulley;
  • connecting rod;
  • drive belt;
  • support rack;
  • wheel;
  • spring
  • The timing belt of the bevel gear.

Fan

The fan digger is attached to the machine (also called the “lancet” and “foot”). In professional language, such a unit is called “dolphin”, because of the corresponding shape of the plow. ploughshare. The design of this machine is simple, but it still achieves a good rate of output. It is possible to make such a unit with your own hands in a short period of time.

How it works: the cutter cuts into the ground layer, the root crops are rolled over the armature, moved along the armature. During this “journey” the tubers are cleaned from the ground. Before harvesting, all vegetation must be removed. To make such a construction, the following tools and materials will be required:

  • hammer;
  • a set of drills;
  • tape measure;
  • marker;
  • bolts;
  • pliers or pliers;
  • A 3 mm thick sheet of steel. it should be used to make the plowshare;

There are cases when the rebar is bent in the form of steps. The tool body itself is fitted with a stand, the height of which depends on the design of the power tiller. The stand-holder can be welded to the plow itself, without the bolt attachment.

From the disadvantages we can mention a relatively narrow strip of cultivated land. it is only 30 cm.

Using such a design, you can lose a significant portion of the crop. up to 22%. Also, some of the tubers are damaged. this will lead to the fact that such a product to leave for winter storage will not work.

Rumble

The screen mechanism is based on the vibration principle and consists of a ploughshare and a screen.

With the help of a ploughshare. “knife”, recessed in the ground to a depth of 25 cm, the layer of soil is undermined together with the root crops. Soil with tubers remains on the grid. Due to the vibration impulses, the soil is swept around the tubers and rolled down, and the cleaned potatoes go into the container.

The scheme is efficient, but it is technically quite difficult to make such a unit, because you need a certain skill.

The design consists of three blocks:

The following tools will be needed:

  • drill;
  • hammer;
  • a set of drills;
  • bolts;
  • wire cutters or pliers;
  • Reinforcement (10 mm);
  • pivots;
  • eccentric;
  • marker.

First cut the profile to the right size to make a frame, which is then welded. Supports are mounted underneath, and the wheels are put on them. In the frame itself are mounted hinge mounts, on which is placed the screen.

Fasteners are welded to the frame. a gearbox is placed on them, special devices that provide vibration. From the reinforcement, the mesh of the box is welded, which is fixed inside the frame. A gearbox is installed, which provides the necessary vibration. It is connected to the screen. Through the lever device and the connecting rod the impulse from the rotation of the shaft comes to the screen and this generates vibrating impulses that generate rotary movements of the eccentric.

A share is cut out of steel, which is attached to the bottom of the frame. Wheels are attached to the machine. The blade can be either concave or slightly convex.

The mill lifts the soil and roots, after which they fall into a screen, on which they roll, freeing themselves from the soil. Then the tubers fall from the surface of the grid onto the ground. The advantage of this device is that the grip is 0,45 meters wide. Gives you up to 0.3 m depth of ground penetration. The crop loss is relatively small. up to 10%.

The disadvantages of the machine are that there is increased vibration, which is transmitted to the operator, and this tires the operator out rather quickly. Also before starting work, all the potato leaves should be removed from the plot to ensure the normal passage of the tiller. In some cases, the vibration is reduced by installing two eccentrics.

Transporter

Self-made conveyor belt potato harvester can be of different sizes. These machines are usually large to handle large areas of crops. To work on the homestead plot enough small potato diggers, which make their own hands is not very difficult. The operating principle is simple: tubers are extracted from the soil and fed into the separator on the conveyor belt.

The band itself is a grid, which is made of welded parallel reinforcement. It is attached to the mobile conveyor belt. The tape is also made of mesh and rubber, which is attached to a dense cloth. The soil adhering to the tubers, separating, falls off, and the potatoes go into storage.

The conveyor moves as a result of the rotation of the shaft, which is attached to the power tiller.

In this case such elements are used:

The cutter is a sickle-shaped metal tool. It plunges into the ground to almost 20 cm. Such device works much “cleaner”, the unharvested crop remains on the fields no more than 5%. Cutter mounting is realized with bolts with lock washers.

Before you start making a potato digger, you need to think about the question of whether you have the practical skills. You should also carefully get acquainted with the drawings. there are a huge number of them on the Internet.

The main elements of the potato harvester:

  • Welded frame. is made of a profile;
  • steel cutter;
  • Rollers, which ensure the movement of the belt;
  • The assembly of steel band reinforcement;
  • fasteners.

The “drum” potato harvester has proven itself successfully in the treatment of large areas.

The machine is made of the following elements:

The cutter is mounted to the base using special hinges. Its function is to remove the soil below the tubers that go into the rotating container. A rotating hollow allows you to free the soil from the tubers that remain in the container. Then the vegetables are moved to the end of the container and fall on the ground in a cleaned form.

The drum is attached to the tractor shaft by means of gears and a gearbox. a torque impulse comes from it. The sickle-shaped cutter allows you to open up the soil to a decent depth, which guarantees the preservation of the crop. such a device provides little loss of crops, tubers are also practically not subject to mechanical defects.

Manufacturing of a vibrating potato harvester

In order to make a homemade potato harvester for a power tiller on a vibrating basis, we will need:

  • Supporting structure of the metal channel;
  • Steel plates for the ploughshare. Steel must be at least 5 mm thick.
  • Steel or iron corners from rolled metal;
  • Steel or iron rods, preferably of small diameter;
  • Metal tube

The potato digger design has a frame, suspension system, control rods, wheels, or other moving units.

The base of the vibrating potato digger

Begin the process of making a potato harvester for your power tiller with your own hands by creating a base.

To weld the frame you need a 4040mm sectional tube. We take as a basis a square tube length of 4 meters, cut parts of 80 cm and 120 cm. The length of the workpiece is enough for 4 pieces that will serve as supporting beams.

The supporting bars are welded at an angle of 90 degrees, creating a rectangular frame with sides of 0.8 m and 1.2 m. The frame is ready.

To create anchorage for tie rods we take the mentioned rectangular base. Use a welder to attach a metal channel one-third or one-quarter of the middle of the frame.

On the reverse side of the frame we weld vertically pipes in order to mount the axle. Subsequently, the movable elements will be installed there.

Drill centimeter holes with an electric drill in a place convenient for mounting.

Taking the indent from the edge of the base not less than 5 centimeters, weld a rack. The length of the square profile is up to 50 centimeters. Step back another 15-20 cm, again we attach a welder second post, less than the previous one, a length of no more than 40 centimeters. Then the measurement is 40 centimeters, the subsequent profile is 30 centimeters, it is also fixed by welding. At the end of the work we have a device, similar to a steam ladder.

Racks are fixed in the lowest compartment of the device with a metal strip. We take a strip of no more than 0.5 millimeters and connect the profiles with a welder at an angle of 45 degrees.

Having designed the main part of a homemade potato harvester, we proceed to the production of the active part of our digger, plowshare, which will perform the bulk of the work on the potato harvest.

To make the plowshare, a blade that will cut the soil, we need a metal plate not less than 0,3 millimeters thick. According to a previously selected drawing, from the plate cut two blades, the main working parts. The blades are fastened with a welding machine, fixed with a special bar. Now it is necessary to give the blade the most voluminous form, for convenient work on digging and grasping the soil. To do this, in the middle of the blade we tap with a hammer.

Rolling board, to put it simply, steel rods or bars, are the necessary part of the working part of the potato shovel. They are attached to the share by welding to the base of the blade.

For making the slope board, steel bars with a diameter of 10 millimeters and a length of 1.2 meters are the best. We need to weld the armature to the ploughshare base at intervals of 4 or 5 centimeters.

This component is not always available. This is only necessary if the soil to be tilled is potentially very watery. They correct the angle of inclination of the sloping board.

The easiest way to make pulls to adjust the potato harvester for power tillers is to make a movable frame that will hold the armature board.

The potato digging implement is completed by mounting support wheels. The design of diggers always involves moving elements for more comfortable movement on the surface of the plot.

Wheels from an ordinary garden wheelbarrow are the best option. The important thing is to use wheels with a wide tire.

Earlier we have already made and fastened the axles to the frame. Now we need to fix the wheels to the axles with a stud, on the same principle as on the garden wheelbarrow.

Many people buy for this purpose various kinds of mechanical inventions, and some craftsmen, so-called hobbyists, are only happy to make their own potato digger, to save themselves and their loved ones from hard work. Particularly popular among the rural workers received a potato hoe, functioning on the basis of a power tiller of any variation, whether it is the model everyone liked the Neva, or a mechanical device from another manufacturer. In this case, the main thing is to have a clear understanding of the design features of the homemade digger for potatoes and the ability to create drawings.

A necessary clarification: this mechanical device is clamped to a power tiller to do the job. Such a unit, made with their own hands, is able to work the land plot both near the house and in the field. The primary purpose of the potato digger is to separate potato tubers from the soil and place them on the ground. Such a machine is easy to operate and has a fairly simple design. That’s why making one yourself is usually not too difficult. The main thing is that this attachment mechanical device will fit any model of power tiller.

Many will argue, why waste time and effort, if such a miracle of technology can be bought without problems at any point of sale of agricultural machinery and devices. This point of view is valid and many do.

However, any experienced vegetable grower knows the main advantages of a digger, created at home:

digger, power, tiller, hands
  • Such a mechanism is much more practical, as it is designed for a particular characteristic of the soil of a particular area, as well as based on the strength of a particular person. the future happy owner.
  • The cost of a homemade device is much lower than that of a ready-made product, sold in specialized stores.

Before starting the creative design processes for designing a potato digger, it should be remembered: it is adapted to function on soils with medium and insignificant index of density. To make a machine designed to work in heavy soils, you can not do without a deep knowledge of mechanics and, of course, physics.

There are the following varieties of diggers for potatoes:

  • Mechanism of the screen or vibrating type. its design mainly includes a ploughshare and a vibrating sieve. Functions this type of potato digger on the basis of the power tiller quite primitive. The ploughshare undermines the soil together with the tuber. Then the fixed transporter grid is connected to work, leaving tubers on its surface, and as if through a sieve sifting the soil. This model is rightly considered one of the most effective in the work, but rather complicated in terms of manufacturing.
  • Transporter type. it is able to work with ease, for example, on the basis of a motor block such as the Neva. The structure of the transporter digger includes a ploughshare and a moving transporter, which has a special hitch to support the tubers on the platform and clear the soil. The transporter unit for digging potatoes is more practical compared to the vibrating type of potato digger. However, it is not advisable to use this type of device on soils with a light density criterion.
  • Arrow unit. by design, it’s the simplest mechanism, which can easily be attached to any model of mini-tractor, say, to the same Neva. It does not contain moving parts; the soil with tubers is cut with a knife. Then the cuttings fall on special rods, where the earth is poured back, and the clean fruits are placed on the surface of the soil. This type of digger is more effective on low-density soils, where the use of other varieties of devices is ineffective.

Before you begin construction, you must first know exactly the density of the soil on which you plan to operate. Keep in mind that where a conveyor mechanism can function perfectly, it will be difficult to work with a lancet type design. In a small farm, it will be most convenient to collect potato crops with a device of relatively small size. Such potato digger should be comfortable during application and to be easily mounted on a one-axle tractor.

Drawings of a potato digger for a power tiller: dimensions, photos

Detailed drawings of fan type potato digger for power tiller photo and video of the device in operation.

As is known, there are two types of potato diggers for power tillers, fan and vibrating types, the most simple in the production fan digger, and its device we will consider.

Fan digger is attached equipment, in this case for power tiller, this is what this device looks like.

The device for digging potatoes is a plough with a fan of rods, while moving power tiller plows into the soil and lifts it on a grid of rods, in turn the rods loosen and sift the soil at the same time potato tubers are thrown already on top of the soil.

The video shows the principle of fan potato digger.
