Abstract

FIELD: agricultural engineering, in particular, removal of weeds such as ragweed.

SUBSTANCE: weed thinning apparatus has handles, clamp cheeks and support, and is further provided with tubular casing with rod introduced therein so that rod ends protrude from tubular casing. One of handles and opposite clamp cheek are attached to tubular casing and other handle and opposite clamp cheek are fixed to rod. Support is made in the form of L-shaped lever with upper pressing and lower stop parts. Support is attached to lower part of tubular casing.

EFFECT: reduced labor intensity for extraction of weeds, in particular, ragweed, from soil.

Description

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

A tool for weeding weeds is known, containing handles and flat clamps rotatable relative to each other, the handles are connected to the corresponding clamps by means of racks, one of which is equipped with a lever with a supporting heel, the clamps being located at an angle to the axes of the racks (see SU 913961 A, cl. A 01 B 41/04, 03/23/1982).

The disadvantages of this tool is that:

1. The efforts of one hand on the handles are not enough to securely hold the plant with a clamp.

2. The pens are located in the area of the removed plant, and a plant such as ragweed will be harmful to the hands.

3. The handles have two racks that do not carry the same load. Between the racks will be leftover weed.

4. A very complex structure consisting of 4 links: a lever, a pedal, a supporting heel - and also it is bulky. Do not just put your foot on the lever, standing on one leg. During operation, the lever changes its inclination and the possibility of a leg jumping off the lever is not excluded.

The technical result that can be achieved using the present invention is to reduce the complexity when removing weeds from the soil, in particular quarantine weeds such as ragweed.

The technical result is achieved by the fact that the tool for weeding weeds, containing clamp cheeks and a support, according to the invention, has a pipe body with a shaft included in it, the shaft ends extending from the pipe body, while one of the handles and the clip cheek opposite to it are attached to the casing-pipe, and the other handle and the opposite cheek clip to the rod, in addition, the support is made in the form of a L-shaped lever with upper push and lower thrust parts and is attached to the lower part of the casing-pipe.

Figure 1 shows the gun Dvoryanidova A.G. for weeding weeds, general view. The gun comes in contact with the weed; figure 2 is the same, the tool begins to extract weed from the soil; figure 3 is the same, the final stage to remove ragweed from the soil; figure 4 shows a clip, side view; figure 5 shows a section aa in figure 4.

The tool consists of a pipe body 1, two handles 2. One handle 2 is attached to the pipe body, the other handle 2 is attached to the rod 3, which is included in the pipe body 1. The upper end of the rod 3 leaves the pipe body 1. The lower end the rod 3 comes out of the pipe body 1 and the left cheek 4 of the clamp 5 is attached to it. The right cheek 6 is attached to the pipe body 1. The inner walls of the cheeks 4 and 6 have notches with an upward slope. Cheeks 4 and 6 below have a protrusion 7 with notches. The protrusions 7 are located in the working area of the clamp 5. In the lower part of the casing-pipe on the right side, a L-shaped lever is rigidly fixed, containing the upper pressure part 9 and the lower thrust part 10.

The gun works as follows.

The tool is brought to the plant (figure 1) so that it is between the two cheeks 4.6. After this, the cheeks are as close to the stem of the plant. The leg is mounted on the upper pressure part 9 and, while holding the implement with a slight inclination forward, presses the clamp 5 into the ground by the force of arms and legs, while it is useful to move the cheeks 4 and 6 with their arms so that they with their protrusions 7 cut off part of the lateral roots of the weed and deepen into the soil. After that, the handles shift with force, and the clamp securely clings to the weed trunk. Then the lever 8, resting on the lower thrust part 10 (figure 2) begins to pull the weed out of the soil. In (Fig. 3), the final stage is pulling the weed out of the soil. Here, a method of pulling a nail with a nail picker is used. The L-shaped lever 8 serves as a support, through which the weed is finally removed from the soil through the casing pipe.

Technical appraisal and economic advantages of the proposed design.

The proposed tool can use two types of physical effort of a person: manual and foot. The use of handles will allow the clamp to hold the weed securely while it is being removed from the soil. Handles are conveniently located in relation to the working. Very simple and compact design. The use of the L-shaped lever played a large role in facilitating the work on weeding weeds. It is made of a rod that forms the upper pressure part in the form of a platform on which it is convenient to install the foot when the clamp is deepened into the soil, as well as when weed is removed from the soil. When removing the weed by the "nail picker" method, the upper push part and the lower thrust part abut against the soil. Part of the bar on the lower supporting part comes into contact with the soil, and so that it does not stick into the soil, it is necessary to make it horizontally flat. This design will be in demand for weeding in gardens and gardens.

Thus, the proposed invention in comparison with the previous and other technical solutions has the following advantages:

- improving the reliability of the design;

- simplification of the design;

- reduction of labor costs.

Claims (1)
