Abstract

Use: for digging and loosening the soil. SUMMARY OF THE INVENTION: A tillage implement comprises a handle with a replaceable working body inserted into the stop clamps. A support point is placed at the lower end of the stop, spring-loaded by means of a spring relative to the stop. An additional handle is placed in the additional clamps fastened with the clamps of the stop, respectively. 3 ill.

Description

The invention relates to hand tools, preferably a shovel type, and can be used for digging and loosening soil.

The purpose of the invention is to reduce energy consumption and fatigue during tillage.

In order to achieve the set goal in a tillage implement containing a working body located on a handle equipped with a stop, the support is provided with an elastic support element, for example, in the form of a support point spring-loaded relative to it, and is fixed on the handle by means of detachable clamps, while at an angle of 50-70 degrees to the handle, in the cavity passing through the stop and the handle, an additional handle is placed, the end of which is rigidly fixed with the stop, preferably by means of additional detachable clamps fastened together with clamps of an emphasis.

In FIG. 1 shows a general view of an assembly tillage implement; in FIG. 2 shows a side view of the stop; in FIG. 3 is a front view of the stop.

The handle 1, with a replaceable working body 2, is inserted into the clamps 3 and 4 of the stop 5. At the lower end of the stop 5 there is a support point 6, spring-loaded by means of a spring 7 relative to the stop. In additional clamps 8 and 9, fastened respectively with clamps 3 and 4 of the stop 5, an additional handle 10 is placed.

The support stand 5, which is an elastic steel frame about 20 cm high, is fixed on the handle 1 so that the support 5, handle 1 and additional handle 10 are placed in the same plane, perpendicular to the plane which the working edge of the working body 2 is placed. In this case, the distance from the working edge to the supporting point 6 should be about 45 cm. An additional handle 10 is attached to the handle 1 at an angle of 50-70 degrees (the end of which is inserted into clamps 8 and 9) of the stop 5. Fixing the stop 5 on the handle 1 and handle 10 in the clamps of the stop 5 ovens

in a known manner, for example, with nails and the like.

Placing the additional handle 10 at a smaller angle may make it necessary to tilt the back, which will increase operator fatigue, and at a large angle, it will make the instrument less convenient to use.

The preparation of the tillage implement for the working one is carried out by the corresponding movement of the handle 1 in the clamps 3 and 4 of the stop 5,

The spring 7 is selected so that the stock of elasticity accumulated by it ensures the lifting of the largest possible piece of soil.

When digging up, the operator holds the tool by the handle 10, with his foot he implements the working body in the soil. After that, the operator, without bending the back, doesn’t have the handle 10 on himself, while the spring 7 of the support point 6 is compressed. Depending on the strength of the digging soil, part of its volume, cut by the working body, will sooner or later separate from the untouched massif ( refers to a greater or lesser degree of compression of the spring 7).

When tearing off a cut piece of soil, the spring 7 spreads out, tossing it on the working body, and thereby destroying it.

Compared with the prototype, the inventive solution provides the operator with the possibility of not bending the back, which reduces fatigue and energy consumption for work. In addition, the digging soil is destroyed into fine particles without additional manipulation of the tool.

The magnitude of the economic effect of using the claimed decision is difficult to assess due to the lack of a basis for comparison.
