Description

The invention relates to agriculture, in particular to hand tools for loosening the soil and weeding weeds, and can be used mainly for processing rows of cultivated plants.

The aim of the invention is to increase productivity and processing quality.

A well-known universal pololnik, copyright certificate (19) SU (11) 1423004 A1, USSR (51), А01В 1/20 (analogue).

Pololnik consists of a handle and a comb mounted on it, which consists of pointed teeth. Such a tool can choose weeds with roots from the soil. Its disadvantages are that weeds quickly accumulate between the teeth in the comb, and they often need to be selected. Therefore, this tool has a very low productivity.

Also known manual tillage implement, copyright certificate (19) SU (11) 1428213 A1, USSR (S1), 4 A01В 1/06 (prototype).

The tool contains a handle with a holder, on the lateral surface of which a stand is rigidly attached, at the end of which an edge with a sharp working edge is rigidly fixed at an angle of 103-107 °.

This tool is a prototype, its shortcomings - weeding is carried out with a knife, i.e. the weed is cut, half of the root or part of it remains in the soil. Soon it will sprout again. It is better to pick the weed once with the root than to cut it three times in one season.

The purpose of the invention is to increase productivity, the quality of loosening the soil, weeding, expanding the applicability of tools.

This is achieved by the fact that in a manual tillage implement that includes a handle with a holder, to the free end of which a stand with a working body is connected, according to the invention, the free end of the implement stand along the axis of the handle is bent down at a right angle, and 2/3 of the length of the bent end of the stand are bent to the side at a right angle with the formation of a two-stage working body with two-sided working edges, moreover, the working body is made of a plate or a faceted or round rod, and the working edges in the section have a triangular shape rmu with an obtuse angle at the apex, or an ellipsoidal shape, or the shape of a semicircle.

In Fig.1 shows a gun, a General view; figure 2 is a section aa in figure 1; figure 3 shows the working position of the gun; figure 4 is a schematic diagram of the operation of the gun.

The tool consists of a handle 1 (Fig. 1), on which a holder 2 is mounted, into the free end of which there is a stand 3 and is locked with a screw 4. The free end of the stand along the axis of the handle is directed vertically downward at an angle of 90 °, and about 2/3 of this end set aside 90 ° and form a two-stage working body in the form of a paw with steps 5 and 6 with two-sided working edges of the front 7-8 and rear 9-10 (see figure 2). The working edges in the cross section may have a triangular shape with an obtuse angle at the apex, or an ellipsoidal shape, or the shape of a semicircle. In this case, the paw itself is made of a plate, or a faceted, or a round rod. The first step 5 of the paw (Fig. 1) is approximately two times smaller than the step 6 of the paw and is intended for processing narrow aisles, and the long step 6 of the paw is for wide aisles, during continuous processing, under various bushes, etc.

The flat paw is oriented with respect to its plane and the axis of the handle and is at an angle of 30-45 °.

The gun works as follows. When inter-row processing, it is necessary, in accordance with the width of the row-spacings, to choose which step of the leg to work with (see Fig. 3). The cannon is thrown from itself to a length of a cutter of 1.5-2 meters, for example, on the opposite side of the bed, a corresponding paw is introduced to the required depth in accordance with the depth of the root system of weeds and short reciprocating movements with an oscillation amplitude of about 5-20 cm, with pressure paws down and to yourself, and down from you - free travel (see the principle diagram of the operation of figure 4) at an angle of 30-45 °, without taking the paws out of the soil to the surface, if there are no obstacles, bring the gun closer to itself, then the cycle repeats etc.

At the same time, the soil is well loosened, and weeds are automatically thrown out onto the soil surface with its root system. After cultivation, it is advisable to sweep the weed into a furrow and dump.
