Description

The invention relates to agricultural machinery, in particular to the working bodies of implements for loosening the soil.

A known working body of a cultivator is a plane cutter, including a paw fixed on it, equipped with flaps made in the form of an extension of the wings, curved upward at an angle to the horizon 1.

A plane-cutting paw is also known, comprising a rack with a lancet paw, on the wings of which guides are made, made in the form of triangular knives 2 vertically mounted on the ends of the wings of the paw wings.

A disadvantage of the known working body and flat-cutting legs is that in them the loosening action of the flaps and guides into the soil is low.

The purpose of the invention is to improve the quality of tillage.

The goal is achieved in that the flaps of the working body are set at an acute angle with respect to the direction of movement and the vertical axis, and grooves are drilled on the flaps, on which hinges of flat disk knives are fixed.

The plane-cutting paw is located asymmetrically relative to the rack. The hinges of the flat disc knives are connected to each other by a flexible member.

In FIG. 1 shows a working body of a tillage implement, side view; in FIG. 2 is a section AA in FIG. 1; in FIG. 3 shows the location of the right flap relative to the direction of travel and the vertical axis.

The working body consists of a flat-cutting paw 1 with a hook-shaped post 2. On the ends of the wings 3 and 4 of the paw 1 there are fixed flaps 5 and 6, which are made in the form of a trapezoid and are installed at sharp angles with respect to the direction of movement (angle ± o) and vertical axis (angle ± /8). Grooves 7 are drilled on flaps 5 and 6, on which hinges 8 and 9 of flat disk knives 10 and 11 are fixed, and the planes of disk knives 10 and 11 are parallel to the corresponding planes of the flaps 5 and 6.

The hinges 8 and 9 of rotation of the circular knives are connected to each other by a flexible element 12. The length of one wing of the leg 1 is shorter than the other wing, the leg 1 being asymmetrically relative to the plane of the strut 2 (Fig. 2). The angle of the solution of si, the short wing is greater than the angle of the solution of ac, the other wing, while both wings have equal capture widths a. A small flat knife 14 is fastened to the pointed lower nose portion 13 of the rack 2. By means of the attachment unit 15, the rack 2 is attached to the frame 16. The working body works as follows.

When the working body moves, the pointed nose part 13 of the rack 2 destroys the soil connections at the depth of the soil treatment. The trail left - a slit with a small but thin (compared to the thickness of the rack) flat knife 14 - reduces the energy consumption for a soil cut by the sharpened edge of the rack 2. Since, firstly, this gap under the action of the rack 2 quickly develops to the day surface of the soil; Secondly,

trace-gap reduces the size of the compacted core in the soil formed in front of the sharpened edge of the rack 2.

The part of the soil that passes through the gap between the rack 2 and the flat disk

knife 10, is cut from below by the wing 3 of the legs 1 and is exposed to the action of the knife 10.- The knife 10 simultaneously cuts off the right wall of the treated formation and deforms the soil, while this part rises slightly

upward (since the plane of the disk forms an angle of ultrasound with the vertical) and is pressed to another part of the soil passing through the gap between the rack 2 and the disk knife 11, cut from the bottom by the wing 4 of the legs 1. The knife 11 forms

the left wall of the reservoir and pushes the entire reservoir into the gap left by the disk 10.

For a short period of time (0.2 ... 0.3 s) the soil is exposed to the opposite effects.

impacts in the soil, intensive crumbling occurs.

Depending on the processing depth, the positions of the hinges 8 and 9 in the grooves 7 are adjusted so that the upper part of the disks 10 and 11

remained above the surface of the soil for the normal rotation of the discs.

Through the flexible element 12, the soil reaction forces (more precisely, their projection onto the axis of the element 12) are balanced

the surface of the discs 8 and 9 and on the lower surfaces of the flaps 5 and 6.

The flexible element 12 increases the strength of the flaps and, depending on the depth of processing, additionally loosens the soil layer,

located above her.

The proposed invention allows for high-quality strip or continuous tillage in a selected area.
