How to connect the potato harvester to the tiller. Vibrating digger with their own hands

Making a potato digger for a power tiller with our own hands

Design features and types

It is worth recalling at once that this mechanical device, as can be seen from the photo, to do the work, is hooked to the tiller. Such a digger, made by its own hands, as shown in the video, is able to work the land not only near the house, but also in the field. To create it, you need metal brackets and a welding machine. If the latter is not available, you can buy welding machines Robu in

Before you start the creative constructive work on the creation of a potato harvester, remember, it is adapted to work on soils with medium and low density criterion. In order to make machines adapted to work on heavy soils, it is necessary to have a deep knowledge of physics and mechanics.

Digger for potatoes, adapted to the power tiller, as shown in the photo, there are such types:

  • Rattle or vibrating mechanism. it consists mainly of a ploughshare and a vibrating sieve. The principle of this type of potato digger that works with a power tiller is simple. The soil is undermined together with the potatoes with the ploughshare. The immovable transporter screen then leaves the tubers on its surface, while the ground is shaken off like a sieve. This model is efficient in work, but pretty complicated in the making.
  • Transporter unit for digging potatoes. it can work freely, for example, on the basis of such motor-block, as “Neva”. By design, a transporter digger consists of a ploughshare and a moving transporter, which has a special hitch device to keep the tubers on the platform and clear the ground. The conveyor design for digging potatoes is more practical than a vibrating type of potato digger. But it is not reasonable to use this type of device on soils with a slight degree of density.
  • Beam type. by design it is the simplest mechanism, which can easily be adapted to any model of mini tractor, such as “Neva. It does not contain any movable parts. As shown in the video, the soil with tubers is trimmed with a knife. Next, the cut falls on the surface of special bars, where the soil is poured back, and the fruits in a clean form lie on top of the soil. This digger is effective on the soil with a low degree of density, where it is not practical to apply other varieties of devices.

Before starting to design such a device, first of all, it is necessary to determine exactly the density of soil, on which it will be used. It is worth remembering that where a transporter design with a lancet type can ideally be used, it will be difficult to work.

Blueprints of homemade and factory-made potato harvesters

For a small farm, so that it is convenient to harvest potatoes, you need to make a small-sized device. It should be easy to operate and easy to hitch to a single-axle tractor.

Potato digger construction: 1. welded frame, 2. blade, 3. conveyor, 4. pulley, 5. connecting rod, 6. pulley of bevel gear. 7. belt, 8. rack, 9. adapter, 10. support wheel, 11. spring tensioner.

In order to make the device under consideration, you need to have:

  • Steel channel.
  • Coulter, molded from high quality metal alloy, with a thickness of at least 5 mm. To make it, you can use a saw from a circular machine.
  • Metal angles of 40 and 63 mm in size.
  • Steel bars. They are required to make a device, as shown in the photo, at least 8 pieces.

To make a device for digging potatoes of the vibrating type requires, first of all, to make a frame. It should be easy to dock, 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 construct such a unit, you need to make accurate calculations and use them to create drawings. Without following this rule, the process of making your own hands will be difficult.

The steps of making a potato digger of the screen type

As can be seen from the video before starting work, it is required to prepare the following tools:

Also, to make a device, you need to prepare bolts and nuts.

  • The stage. making the frame. To do this, as shown in the photo, sawn into four pieces of square tube. Two pieces should be 1200mm and two pieces should be 800mm. The size of the pipe is 4040 mm. Prepared parts are connected by welding into a rectangle.
  • Stage. Fixing the crosspieces. From the video we can see that they are necessary for the installation of vertical control rods. Fix this element by about a quarter of the length of the frame base. At the other end, two elements for mounting the wheels are attached. Such element must be made of two tubes with diameter of 30 mm and length of 150 mm.
  • Stage. the installation of vertical type posts. On the side where the bars are mounted, at a distance of 5 mm from the edge of the frame are mounted vertically two squares of size 3030 mm and a length of 500 mm. After that, at a distance of 200 mm long uprights of 40 mm are installed. Then another 400 mm must be removed and 300 mm long posts fixed. Join the uprights together with a 0.4 mm strip.
  • Stage. making the frame. First, on a metal sheet 400400 mm thick, having a thickness of 0.3 mm, and at the bottom of the posts, two holes are prepared for mounting. The workpiece is rigidly attached to the uprights. The same piece is attached to the other side. Another square of 700700 mm sheet metal and 0.4 mm thick is welded butt-welded to the first element, and then, using a sledgehammer, bent into the desired cone configuration.
  • Stage. design of the trellis. To do this, a rod with a diameter of 10 mm is attached to the bottom of the finished frame, and the other end goes beyond the perimeter of the frame towards the pulling mechanism, which can be a model “Neva”.

Potato harvester for the Neva power tiller: vibrating, homemade, ploughing

Potato harvester for the Neva power tiller. attachment equipment, which allows the most rapid, efficient and high quality harvesting of crops from the plots of land.

Until recently only large agricultural enterprises performed mechanized harvesting. Now even small farmers are trying to speed up and simplify the process. Having power tillers or mini-tractors, farmers think about buying additional mechanisms that reduce physical labor and increase productivity. Today’s market offers a wide range of mounted agricultural equipment, such as:

This review will consider the main models of potato harvesters for power tillers “Neva”, their characteristics and principle of operation.

Here are the basics

In most cases power tillers and power tillers are not used on large territories, they cannot cope with large amounts of work on heavy soils. Such equipment is designed for small and medium-sized farms to work on light and medium soils.

The single-axle tractor “Neva” is considered to be the most popular unit among the owners of agricultural lands, it is characterized by high technical indicators, a long service life.

Neva” motor-blocks are not very efficient on their own, but they can perform any agricultural work with the help of additional equipment:

  • Motor cultivators are suitable for dacha owners and farmers for tillage;
  • planter in aggregation with a power tiller. for planting of vegetable plants on land plots;
  • mowers. for mowing grass;
  • potatoes are mowed with hoppers;
  • for mechanized harvesting of root crops, a potato digger is used.

Recently, farmers have been using modern agricultural machinery to grow vegetable crops.

Planting potatoes with “Neva” power tiller helps to save time considerably, allows to cultivate large areas, contributes to better harvest due to soil loosening. The process is carried out in 2 ways:

potato planter for a “Neva” power tiller is used by owners of large plots of land. It is more effective: it makes furrows in the ground in one pass, empties the tubers from a special hopper and covers them with soil.

Harvesting process is carried out by a “Neva” power tiller with a potato digger. The tines of the mechanism dig into the ground, pushing out the root crops and laying them on the surface for further collection by hand.

There are several models of diggers, aggregated with the motor-block “Neva”:

  • Fan.
  • Vibrating. Includes such well-known models among agrarians as:
  • KKM-1;
  • “Vibrating Potato Digger” model;
  • KVM-3;
  • “Poltavchanka”.
  • Transporter or belt.

These models are considered the most popular and widespread.

Fan spudder

Such mechanism is called a simple, passive and universal potato harvester. It looks like an ordinary heart-shaped shovel, with teeth in the upper part. The sharp part lifts the soil. Caught on the tines, the soil is crumbling along with the potatoes, the rootcrops remain on the surface.

Advantages of a fan potato digger for a power tiller:

  • lightweight attachment on a single-axle tractor;
  • aggregation with small power tillers;
  • Root crops are dug at high speed;
  • low price;
  • simplicity of design;
  • reliability.

The disadvantages of the mechanism include such factors:

    Small technological indicators. the depth of digging is 15 cm, width of capture up to 20 cm;

Fan mechanism has several models, which are designed to work on light soil. The devices are designed for small power tillers, perfectly suited for “Neva MB” power tillers.

KKM-1 potato harvester

Such a machine is called a vibrating potato digger for the “Neva” motor-block screen type with a more advanced design. The module consists of an active plowshare and a sifting screen-grid. Plowshares undercut layer of soil, which enters the screen mechanism. Then the layer is crumbled on the screen and sifted between the bars due to the vibrations. Clods of soil that didn’t pass through the grid, root crops and haulm are thrown on the surface along the machine’s trail.

Rumble diggers are designed to harvest potatoes with a row spacing of 60-70 cm.

With the help of a vibrating potato digger can pick up onions, garlic, beets, carrots.

KKM-1 unit has the following technical characteristics:

  • overall dimensions. 700x700x600 mm;
  • the weight of the machine. 40 kg;
  • Productivity. 0,05-0,2 ha/h;
  • working speed of the machine. 1.1-2.1 km/h;
  • digging depth. 20 cm;
  • working width. 39 cm;
  • unit’s turning radius at the outermost point. 3 m.
  • ability to work on heavy soils, with soil hardness up to 20 kg/cm², rock-clogged soils up to 8-9 t/ha;
  • large working width and digging depth;
  • High efficiency of potato harvesting. 98%;
  • good tuber cleaning during vibration;
  • time saving;
  • ease of use on large areas;
  • low fuel consumption.

Vibrating diggers are aggregated with power tillers “Salyut”, “Kaskad”, “Favorit”, “Neva MB 2”, MT3.

Vibratory potato harvester model

Single-row vibrating potato puller is designed for digging potatoes and other root crops, made especially for all Russian “Neva” (MB, MB2) power tillers. The operating mechanism is similar to a vibrating shovel.

Technical characteristics of this model are as follows:

  • overall dimensions. 710x680x730 mm;
  • weight. 34 kg;
  • working width. 36 cm;
  • digging depth. 20 cm;
  • Speed. 2 km / h;
  • productivity. 0,2 ha/h.

The simplest potato harvester for power tiller with your own hands

Even the simplest digger, made by your own hands, will facilitate labor when harvesting potatoes with a power tiller. The advantages of self-made are obvious:

  • will not require significant financial investment;
  • While manufacturing, the farmer takes into account the soil characteristics of his own plot and of the tiller, to which the equipment will be attached;
  • No professional workshop services are required for maintenance and repair.

Passive arrow type potato digger. the simplest hinged mechanism, made like a bayonet shovel from a bent sheet of iron and rods, welded a fan, to sift out the ground.

This modernized digger does not require a detailed drawing and can cope with the collection of root crops on a plot with light soil. Even a novice homemaker can make it.

How to make a potato digger for a power tiller

Most people in the countryside have homestead plots. In the fall, harvesting adds to the work. Harvesting potatoes is a labor-intensive activity that requires automation. Otherwise, the work will move slowly and hard. It is not profitable to use a shovel.

A single-axle tractor is a common vehicle on the homestead. People try to buy attachments for it. This also includes a potato digger. However, there are craftsmen who independently make a potato harvester for power tillers. Some will note that it is easier to buy a ready-made product. However, the following advantages speak in favor of the homemade potato digger:

  • The possibility of sharpening to suit the characteristics of the soil.
  • Individual dimensions, convenient for the farmer.
  • Sharpening for a certain model of power tiller or making a universal spade, if necessary.
  • Saves a lot of money.

The main thing when making a potato digger with your own hands is to have an idea about the future product.

Pay attention! The purpose of the potato digger is to separate potato tubers from the soil and place them on the ground. The device is characterized by a simple design, so self-made is not difficult. However, a homemade digger will only be effective on light and medium-heavy soil.

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

Vibrating potato harvester 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;
  • steel channel;
  • section of steel;
  • coulter from 5 mm;
  • metal corners (40 and 60 mm);
  • profile pipe;

Important! The first step in assembling a potato digger is to develop a drawing. When creating a diagram with your own hands, you need to specify all the parameters on it, including the dimensions of the motoblock.

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

Algorithm of making a screen potato digger for a power tiller with your own hands:

  • The first thing to do is to build the frame of the device. To do this, the pipe must be sawed into four parts. In pairs they should have a length of 120 cm and 80 cm.
  • The resulting segments are welded to the shape of a rectangle.

Important! It is necessary to take into account the weight of the final design and try not to overload it with unnecessary elements. An overly cumbersome unit will interfere with the smooth operation of the system.

Conveyor digger for heavy-duty pulling devices

Heavy-duty farming equipment also requires an appropriate attachment, since the work involves large areas. This means that the work must be mechanized as much as possible. So, the conveyor digger is the most complex in design, with the largest number of rotating elements.

The harvested crops are practically ready for storage (tubers are whole and clean). High productivity is ensured by the fact that the tractor attachment provides for two rows of cultivation, not 1 row at a time, which is provided by a power tiller.

To make such a universal conveyor yourself is extremely difficult. Factory models are expensive, but large farms can purchase off-the-shelf designs. For example, for quality and fast harvesting with a mini-tractor designed mounted two-row potato diggers DTZ-2B or DK-2T.

Making a shaker type digger

Note! Rumble, shaking shovel is made in just a few hours, if you have some skills in working with agricultural machinery. It consists of only 3 basic elements:

It consists of only 3 basic elements:

  • steel plate (5 mm);
  • metal profile;
  • metal drills;
  • a welding machine;
  • angle grinder, drill;
  • steel wire (8 mm in diameter);
  • eccentric;
  • bolts;
  • a pencil with a ruler.
  • cut the metal profile for the frame;
  • Weld the racks for the wheels to the bottom of the frame;
  • Weld holders for the hinges to attach the screen inside the frame;
  • Screw in the brackets to mount the gear by welding them to the frame;
  • to suspend the screen inside the frame on hinges;
  • fit the reducer on the brackets;
  • connect it to a screen to create vibration;
  • cut the blade out of steel;
  • attach it to the lower part of the frame and the screen by putting it on hinges;
  • attach the wheels by putting them on the machine.

Please note! You can make the knife of any shape you wish: convex, concave, bent, sharpened. The model at work will not rattle, but only be constantly in an oscillating state, cutting the soil with tubers and slightly tossing them up

They will fall already cleaned behind the machine or on the side of the strip, rolling off the grid

the model will not rumble during work, but only be in a constantly oscillating state, cutting the soil with the tubers and tossing them slightly upwards. They will already fall in a cleared form behind the unit or on the side of the strip, rolling off the grid.

Transporter potato harvester

Another modification is a transporter potato plow. Transporter unit is installed on medium and heavy motor blocks. By its characteristics similar to a vibrating device. The difference is that the potatoes move and are cleaned from the stuck soil on the conveyor belt, instead of being collected on the vibrating table. This type of digger is more practical than a vibrating one, but its use is appropriate only for heavy soils.

Conveyor belt is often made of rods. But also applies the steel mesh, there are models with a rubber band on a fabric base. Conveyor movement is carried out by the transmission of torque from the shaft of the engine block through the gearbox, chains, gears.

The conveyor belt does not damage tubers, is easy to operate, and is compatible with powerful motor-driven tractors and mini-tractors. Industrial samples have the following technical characteristics:

  • overall dimensions. 1140x740x47 mm;
  • weight. 36 kg;
  • speed. 2 km/h;
  • The depth of digging. 20 cm;
  • Working width. 53 cm.

Self-made transporter potato digger after studying the schemes of the factory machines is possible, if the master has experience in such work. Every craftsman can be ingenious and add his own elements to the design solution to improve the finished product. The general assembly instructions are as follows:
