Abstract

A multifunctional hoe-hoe containing a working body in the form of an irregularly shaped plate with sharpened upper and lower edges and a holder for a handle, characterized in that the working body plate is made in the form of a rectangular trapezoid curved both in length and in width at an angle of 1- 3 ° to the axes of the trapezium, the upper and lower edges are sharpened, the upper edge being made in the form of a concave semicircle, and the holder for the handle is conical, with a small part of the cone welded perpendicularly to the working body in the center of intersection of the bisectors of the trapezoid.

Description

The utility model relates to agricultural machinery, in particular to garden hand tools for loosening the top soil layer, rooting out small bushes and weeds with a root system up to 12-15 mm in diameter, thinning crops, inter-row cultivation and destruction of weeds by cutting in fields, household plots gardens and gardens.

Various designs of agricultural implements and tools for performing tillage operations are known: choppers, hoes, harrows, rakes, cultivators, etc. Known hoe for cultivating, cultivating cultivated plants and weeding weeds, made in the form of a plate in the form of an isosceles trapezoid with a sharpened base in the form of a blade forming sharp working angles on the sides of the trapezoid (see RF patent No. 2112330, IPC A01B 1/06). In this device, to increase productivity due to deepening and movement of the plate as a wedge, the steel rod for attaching to the handle plate is flattened and rotated at a certain angle to the axis of the handle, and the plate is also turned to the center line at a small angle to the axis.

This hoe is difficult to manufacture, and its use is limited only by loosening the soil.

The closest in technical essence to the proposed utility model is a universal manual pololnik (see RF patent No. 226428, IPC A01B 1/06), made in the form of a plate with pointed edges and a holder for the handle. The working plate is made in the form of a quadrangle with a right angle at the apex on the side of the holder holder and with an acute angle formed by equal sides of the plate, while the center of gravity of the plate is rotatable on its plane.

With all the advantages of a universal manual pololnik, its disadvantage is that it does not perform the functions of uprooting large weeds and small bushes. It is impossible for them to weed and cut weeds in narrow places between rows of agricultural crops. The angle of attachment of the holder with a working plate is 75 ° -80 °, which causes certain difficulties in the manufacture of this pololnik.

The technical task of the utility model is the creation of a multifunctional hand-held agricultural implement, convenient for working with a minimum expenditure of human energy and easy to manufacture.

This is achieved by the fact that in a multifunctional chopper-hoe containing a working body in the form of a plate of irregular shape with pointed upper and lower edges and a holder for a handle, the plate of the working body is made in the form of a rectangular trapezoid with an oval plane curved both in length and along width at an angle of 1 ° -3 ° to the axes of the trapezoid. The upper and lower edges are sharpened, and the upper edge is made in the form of a concave semicircle. The holder for the handle is cone-shaped, with a small part of the cone perpendicularly welded to the working body at the center of intersection of the bisectors of the sides of the trapezoid adjacent to the right angle.

Due to the fact that the working body is made in the form of a rectangular trapezoidal plate with an oval plane, curved both in length and in width at an angle of 1 ° -3 ° to the axes of the trapezoid, structural rigidity is provided with its relative lightness and gives the properties of a hoe.

The multifunctionality of the chopper-hoe is that, if necessary, work is carried out by all four sides with a rotation of the working body by 90 ° -180 °. This is also achieved due to the fact that the holder for the handle is welded with a small part of its cone at the center of intersection of the bisectors of the sides of the trapezoidal plate of the working body.

The lower and upper edges of the working plate are sharpened from the outside at an angle of 12 ° -15 °.

Making a hoe-hoe with a right or left bevel gives it convenience when working with both “right-handed” and “left-handed”.

The concave top edge can more accurately and deeply cut the roots of thick weeds and uproot the roots of shrubs.

In the process of work, many types of operations are performed, which reduces the time it takes to complete the work, reduces the cost of human energy for tillage, and generally improves labor productivity.

The utility model is illustrated by drawings.

Figure 1 presents the working body of a multifunctional chopper-hoes;

- figure 2 is the same side view along the bottom ground edge;

- figure 3 is the same, side view along the not sharpened edge.

The multifunctional chopper-hoe consists of a plate 1 in the form of a rectangular trapezoid with an oval plane, curved both in length and in width at an angle of 1 ° -3 ° to the axes of the trapezoid. Edges: 2 - upper and 3 - lower - sharpened from the outside at an angle of 12 ° -15 °, and the upper edge 2 is made in the form of a concave semicircle. Edge 4 is located at right angles to edge 3. Edge 5 is the widest part of the working plate. The holder 6 for the cone-shaped shank with a small part of the cone is perpendicularly welded to the plate at the center of the intersection of the bisectors of the sides of the trapezoid adjacent to the right angle.

During operation, the chopper-hoe is held in the hands with that side down, which is necessary for this type of agricultural work. The upper concave edge 2 allows you to loosen the soil of any density without much energy, pruning and uprooting the roots of thick weeds and small bushes with a diameter of up to 12-15 mm at a depth of 120-150 mm. This edge can also weed in narrow places between crops and make triangular grooves up to 150 mm deep for planting.

With the lower (opposite) edge 3, the root system of weeds is cut, the agricultural crops are earthed, deep holes and trapezoidal grooves are made.

With edge 4, it is possible to pick up, to cultivate agricultural crops, with a certain pressure to rake the top layer of soil, without pressing the handle, to rake felled weeds and debris lying on the surface.

Edge 5 break up large hard stones of the soil, rake weeds and debris, level the topsoil.

When using the edges 2, 4 and 3 of the multifunctional chopper-hoe alternately, it is convenient to dig potatoes, dig out beets and carrots.

It is rational to use the multi-functional hoe-hoe for people of different heights and ages of small, medium and large sizes with the following aspect ratio in mm:

Edge 2 Edge 3 Edge 4 Curvature by minor axis in degrees major axis in degrees Small twenty one hundred 200 1-2 2-3 Average 25 125 250 1-2 2-4 Big thirty 150 300 2-3 3-5

For work with a multifunctional hoe-hoe, it is recommended to use an oval-shaped wooden shank with a length corresponding to the height of the worker. In the cross section of the axis of the ovals: small - 28-35 mm and large - 35-40 mm. When using the oval handle, it is attached to the holder so that the major axis of the oval is parallel to the edge 4. In this case, the working plate of the multi-function chopper-hoe does not scroll in the hand, since in the palm of the hand the oval is located along or parallel to the axis of the worker and the handle can be held freely, not tough. At the same time, the working body with the upper and lower edges confidently performs the specified operation (loosening the soil, rooting out, cutting weeds, picking up the soil, and hilling agricultural crops).

When working with non-pointed edges 4 and 5, the stalk in the hand is perpendicular or transverse to the axis of the worker, and we can confidently perform raking of weeds, debris, leveling the surface of the soil, wide raking of the soil, and earthing up agricultural crops.

For the manufacture of a working plate, steel is recommended, from which ordinary bayonet shovels or 30KhGSA are made, and the holder material is steel 20, the latter being electrically welded to the working plate. Sharpening of the working edges 2 and 3 is carried out after beating, without heating, without teeth. The curvature of the working plate along the axes gives the multifunctional chopper-hoe rigidity, which allows a reduction in the thickness of the steel plate and, accordingly, its weight.
