Description

The invention relates to gardening tools and can be used in agriculture for loosening the soil and removing weed grass roots in gardens, gardens, where the development of soil by mechanized means is impossible or disadvantageous.

It is known that in the conditions of garden work, the soil is loosened by a shovel, pitchfork. When processing only one hundredths to a depth of 25-30 cm, it is necessary to loosen 25-30 m ^{3 of} soil, perform about 7000 cycles (introducing forks (shovels), tearing, lifting, throwing and grinding a portion of the earth) in a half-bent state, manipulating the forks (shovel) which are close in weight to the cultivated portion of land. The main disadvantage of this technology is its high complexity.

Closest to the claimed is a technical solution according to patent SU No. 1806478 A1, A01B 1/02, publ. 04/07/1993, according to which the SHOVEL contains a blade with a holder, a handle, pivotally connected to the supporting element, the swivel is made in the form of a sleeve having a rectangular groove and a hole perpendicular to its axis of rotation, in which a rod is installed by means of a threaded connection, the other end attached to the support element, made in the form of articulated jibs connected by a spring and having pivotally mounted support discs at the ends, pivot stops are attached to the jibs from the side of the articulation a company in the form of angles, a lever is attached to the end of one of the jibs, and a plate having a surface corresponding to the shape of the groove is fixed on the handle in the sleeve groove, while its two straight sections are smoothly rotated 90 ° relative to each other, and ring ends are fixed at the ends emphasis.

Turning the soil with a well-known shovel is carried out not by rotating the handle with the blade, but by pressing the handle and pushing it forward from itself. Rearrangement of the shovel with the help of a lever-articulated walking device that does not require tangible inclinations and turns is more convenient, facilitates labor and increases productivity.

Disadvantages: the bulkiness and complexity of the design, which by its weight reduces the benefits to facilitate labor, and also increases the cost of the known device.

The disadvantages of the prototype eliminates the claimed technical solution.

The digger-ripper is designed for loosening the soil and removing weed roots.

The aim of the invention is to significantly facilitate work on loosening the soil while removing the roots of weeds and a significant increase in productivity.

The technical task is to create the design of a hand-held device for the simultaneous implementation of the following operations in the development of soils: cutting off part of the soil from both the back and side sections with cutting weed roots, crushing and sifting the soil to separate weed roots, removing weed roots that have been cleaned from the soil herbs, increasing labor productivity, reducing the complexity of work in soil preparation.

SUMMARY OF THE INVENTION To solve the technical problem, the following design is proposed: the digger-ripper contains a blade 1, which is a cutting plate with 90 ° bent ends with a sharp sharpened lower edge of the plate. The lower ends of the rods are welded to the blade 1 by electric welding, and the upper ends of the rods are welded to the holder 3. The handle 4 is fixed to the holder 3. A removable movable sleeve 5 consisting of 2 halves connected by a hinge 6 is fixed on the handle. To the lower half of the sleeve 5, a plate 7 with two holes is attached by electric welding. The lower hole serves to fix the axis 8 in it, and the upper one to fasten the lock pin 9. The rod 10 is connected to the plate 7 by the rod 10, and a spring ring made of a strip of sheet steel is fixed to the lower end of the rod.

The essence of the technical solution is illustrated by the images in FIG. 1-3 where

2 - bars forming a lattice;

3 - holder;

4 - stalk;

5 - removable movable coupling;

6 - hinge;

10 - rod;

11 - spring ring;

12 - clamping screw.

FIG. 2. Scheme of application of the device.

FIG. 3. The mounting ring-spring in the analysis.

The technical result is a decrease in the complexity of loosening the soil with an increase in labor productivity.

The claimed technical result is achieved due to the construction of the digger-ripper, which contains a blade, a handle, a holder and an emphasis, the blade is made in the form of a plate with ends bent by 90 ° and a sharpened lower edge, and the holder is fixed on the handle and is rigidly connected to the blade using rods forming a lattice, and on the handle with a possibility of movement, a coupling is installed consisting of two parts interconnected by a hinge, to the lower part of which a plate with holes for hinging COROLLARY support rod formed as a spring-ring. As a special case, the spring ring is made of a strip of sheet steel.

When raising the blade, the weight of the soil separated from the array and the weight of the digger-ripper through the detachable clutch and the rod will be applied to the spring ring, which, working as a stop, will be compressed significantly and after sifting and crushing will end it will again take the previous shape of the ring.

Usage: for the development of soils during gardening.

Implementation example: the digger-ripper contains a blade 1 made in the form of a cutting plate with ends bent by 90 ° with a sharpened lower edge, to which the lower ends of the rods are welded (for example, by electric welding), and the upper ends of the rods are welded to the holder 3. The handle 4 is fixed to the holder 3. On the handle 4, a detachable sleeve 5 is fixed, consisting of 2 halves connected to each other by a hinge 6. A plate 7 with two holes is attached to the lower half of the sleeve 5 by welding. The lower hole is intended to be connected using the axis 8 with the support rod 10. And the upper one is used to fix the posts 10 with a pin 9 at the required angle of inclination with respect to the handle 4. At the lower end of the rod 10, a spring ring 11 is fixed from a steel sheet strip using a clamp bolts 12.

Work with a digger-ripper is as follows. At the required height of the handle 4, the coupling 5 is fixed. A support rod 10 is attached to the plate 7 using the axis 8. The spring-ring 11 is attached to and secured by the clamping screw 12 to the bottom of the rod 10.

The holder 3 with rods 2 and fixed to them by electric welding in the lower part of the cutting blade plate is lowered to the ground and is pressed into the soil by pressing the foot on the support face of the holder. By pressing the top of the handle 4 down through the coupling - rod - ring-spring force is transmitted to the holder 3, and it rises up. In this case, the whole weight of the digger-ripper with soil will be taken over by the spring ring 11, and it will be compressed. With insignificant efforts applied to the upper part of the handle 4, both up and down, and horizontally from left to right, vibrations are created, and the soil on the rods will grind and fall down, and the roots of weeds will remain on the rods and then be removed.
