Abstract

The claimed technical solution relates to agricultural technology and may find application in household and garden plots and vegetable gardens for working the soil. A potato digger comprises a handle and tines having a fixed part, and is characterised in that the handle comprises a fixed part and a tipping handle, the moving part of the tine is secured on a hinge in the upper part of the fixed part of the tines and is connected to the tipping handle by means of rod so as to be able to transmit force via the rod when the tipping handle is bent, with the result that the moving part of the tines assumes a perpendicular position relative to the fixed part of the tines, the tipping handle is equipped with a return spring, and at the tipping site of the handle a support handle is mounted perpendicular to the fixed part of the handle.

Description

POTATO

FIELD OF TECHNOLOGY

This technical solution relates to agricultural machinery and may find application in household plots and gardens and vegetable gardens for tillage.

BACKGROUND

The prior art device for soil cultivation (RU2286662C2 from YL 1.2006), containing teeth combined in the upper part with a jumper, a stand articulated to the pedal, an elastic element connecting the pedal to the stand, the grill in the lower part of the rack, and a foot support platform on the bridge, characterized in that the foot support is made in the form of a rigidly connected to the bridge and directed to the side opposite to the working surface of the teeth, U-shaped support and opposite to it relative to the bridge of the heel, which mounted on the jumper at an angle of 0-15 ° relative to the support plane in the direction of the rack, while the jumper is rigidly connected to the pedal, the teeth are made with an acute angle at the apex, and the rack with the handle.

Also known is a manual potato digger RKK-T (RU11948U1 from 16L2L999), which includes forks in the form of a comb with a shoulder strap for a handle with a handle, an emphasis with a support part and a detachable connection, characterized in that the emphasis is made in the form of a triangle, one side docked with the handle using detachable connections, and the forks are equipped with an additional pad as a leg support, and on the supporting part of the triangle is installed with the possibility of movement relative to it base for the convenience of the user.

The most similar to the claimed technical solution can be called the development of the company Mole Harvest

(https: //msk.novobyt.rn/catalog/kartofelekopalka-krot). This is essentially a pitchfork with reference area. Their difference from ordinary pitchforks is that the lever, which abuts against the supporting surface, allows you to minimize efforts when performing a working action with a pitchfork (dumping a layer of earth).

SUMMARY OF THE INVENTION

The objective of the claimed technical solution is to improve existing devices to achieve greater reliability, speed and ease of use.

The technical result is the expansion of the arsenal of technical means.

The technical result is achieved due to the fact that the potato digger contains a handle, forks having a fixed part and a moving part, and differs in that the handle contains a fixed part and a tipping handle, a movable part of the forks mounted on a hinge, which is connected to the tipping point the handle by means of a traction with the possibility of transmitting force through the traction when the tipping handle is bent, as a result of which the movable part of the forks occupies a perpendicular position relative to the fixed hour and fork mechanism turning handle is equipped with a return spring in place Quitting handle mounted support handle perpendicular to the fixed portion of the handle.

BLUEPRINTS

The design of the claimed design of the technical solution is illustrated in FIG. 1 - FIG. 4 on which:

1 - fixed part of the pitchfork;

2 - movable (lifting) part of the pitchfork;

3 - fixed (lower) part of the handle;

4 - supporting handle;

5 - thrust of the tipping mechanism; 6 - tipping (upper) part of the handle;

7 - an arm of fastening of draft;

8 - a return spring.

DETAILED DESCRIPTION OF THE DECISION

The proposed design is a fork, which has a fixed (like conventional forks) part 1, in the upper part of which a movable part 2 is fixed on a hinge, which is connected to the tilt handle 6 by a part of the fork handle by pulling 5. When retracting the tipping part 6 of the handle, by means of transmission forces through the rod 5, the movable part of the forks 2 is diverted, as a result of which the movable part of the forks 2 occupies a perpendicular position relative to the fixed part E. The tipping part of the handle 6 of the forks is equipped with a return spring 8, allowing pull the device into its initial position. In the place of breaking the forks, a support handle 4 is installed, perpendicular to the fixed handle of the forks 3, the support handle 4 can be installed both on the left and on the right side.

The forks are pushed into the ground, for example, near a potato bush, with the foot resting on the top of the fixed part of the forks 1 and with the hand in the support handle 4, with the second hand, the tipping part of the handle 6 is retracted, as a result of which the movable part of the forks 2 takes a perpendicular position with respect to the fixed part of the pitchfork 1, taking out root crops and fragments of the earth from the soil.

In the claimed technical solution, the working action (dumping of the earth) is performed by bending (breaking) the handle. That is, the principle of operation is completely different from the analogue and has several advantages:

E It is not necessary to control the lever stop in the bearing surface, but it is possible to carry out a working action immediately after introducing the forks into the ground. 2. Since the emphasis on the surface is carried out directly through the forks stuck into the ground, and not through a lever having a small contact area with the supporting surface, the working action is faster and easier during its implementation, the movement is fast and stable.

3. The movement necessary to carry out the working action is much shorter, it can be performed practically without bending, thereby reducing the risk of injuries to the back.

4. When the handle is bent, the movable part and the fixed part of the forks forms a horizontal shelf in which dug root crops remain, which allows them to be shaken to remove excess land.
