Description

The invention relates to agricultural machinery, in particular to devices for weeding.

Known hand tools for weeding, made in the form of tse ~ shcheoobraznyh clamps (1].

However, they do not provide reliable weed capture and do not perform the required weeding quality.

Known tool for weeding, containing handles and pivoting relative to each other flat clips [2).

A disadvantage of the known tools is the complexity of the extraction of weeds from the soil.

The purpose of the invention is to reduce the complexity of the extraction of weeds from the soil.

The goal is achieved by the fact that the handles are connected to the corresponding clips by means of racks, one of which is provided with a lever with a supporting heel, the clips being located at an angle to the axes of the racks.

In addition, the clamps are provided with wedge-shaped coefficients located on their lower sides.

The instrument contains racks 1 with handles 2 in the upper part and flat relative to each other.

¹⁰ clamps 3 at the bottom. Handles 2 and clips 3 are fixed at an angle to the posts.

1. Swivel racks 1 made through the loops 4.

One of; The pillars 1 have an edge 5 on which the lever 6 with the pedal 7 and the support heel 8 are pivotally fixed. The support heel 8 is connected to the lever 6 by means of a rack 9 fixed to the lever 6 pivotally. The rib 5 and the post 9 are additionally connected by a link 10, which forms with the lever 6 a four-door broom. On the edge 5 there is a ring 11 for fixing the lever 6 in

the inoperative position, and on the handles 2 a spring release 12. The clips 3 have wedge-shaped projections 13 with blades 14 on the lower sides. The clips 3 and the projections 13 are made with notch 15.

The tool works as follows.

The worker installs the implement in such a way that the weed is between the clips 3. After that, the vertical force presses the protrusions 13 into the soil, cutting off the lateral roots of the weed, and then pulls the clamp 3 through the handles 2 and presses the weed stem. By pressing the pedal 7, the pillars 1 are raised and the weed pinched by the clips 3 is removed from the soil.

The weed curing reaction is perceived by the supporting heel 8. After removing the weed from the soil, the worker releases the knobs 2, while under the action of the spring 12 the clips 3 diverge and are released from the weed. Connection of handles 2 with clips 3 by means of racks 1 with lever 6 fixed on one of them with supporting
