Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular to flat cutters. The purpose of the invention is to reduce clogging of the working body. The working body contains a stand 1, a flat-cutting tape With plowshares 2, toothed discs 3 of larger and smaller diameters installed with the possibility of free rotation on the axis 4, inclined knives 5 at the ends of the plowshares 2, knockbacks 6 located behind the discs 3 of larger diameter are located below the blade level Plowshares 2, and the lower points of the disks 3 of smaller diameter. The lower points of the discs 3 of a smaller diameter are higher than the blade level of the plowshares 2. At the same time, the upper points of the discs 3 of a smaller diameter are located above the back of the plowshare 2. The working body loosens the soil with resistant 1, plowshares 2, discs 3 and at the same time applies fertilizer fertilizers to the soil. The larger diameter discs 3, hooking at the bottom of the furrow, rotate counterclockwise, and the smaller diameter discs 3 - in the opposite direction. This contributes to the self-cleaning of discs 3, preventing them from clogging with soil, which significantly improves the quality of processing. 2 hp ff, 2 ill. (Ls

FIELD OF THE INVENTION The invention relates to agricultural machinery engineering, namely to flat cutters.

The purpose of the invention is to reduce clogging of the working body.

Figure 1 shows the working body, rear view: figure 2 is the same, top view.

The working body contains a rack 1, a flat-cutting paw with plowshares 2, toothed discs 3 of larger and smaller diameter, alternately mounted on the axis 4 at an angle to the direction of movement, inclined knives 5, mounted on the side edges of the plowshares 2 paws, tukoprovoda 6 attached to the rack 1 and located behind the discs 3 of smaller diameter. The lower points of the larger diameter disks 3 are located below the blade level of the plowshares 2 paws, and the lower points of the smaller diameter disks 3 are located above the blade level of the plowshares blade 2. The upper points of the smaller diameter discs 3 are located above the back of the plowshares 2. The disks 3 are installed on the axis x 4 with the possibility of free rotation

The working body for soilless tillage works as follows.

When the working body penetrates and moves in the soil, the reservoir is first loosened by the resistant 1, simultaneously trimmed by the plowshares 2 and fed to the disks 3, which finally loosen the soil. In this case, the larger diameter disks 3 rotate counterclockwise, hooking their lower points to the bottom of the groove. The smaller diameter discs 3 rotate under the action of the soil flow at their upper points in a clockwise direction. Rotation of the alternately installed large and small disks 3 in opposite directions prevents clogging of the interdiscipline between the soil and plant residues, and promotes self-cleaning. Along the tube lines 6, which are located behind the disks 3 of smaller diameter, the tukas are supplied to their lateral surface and are distributed in the soil.

The use of the proposed device allows to improve the quality of

tillage.

Claims (3)

1. A working body for soilless tillage, containing a stand with a flat-cutting paw, behind each plowshare of which, by means of an axis, are mounted toothed disks at an angle to the direction of movement of the dapa, characterized in that, in order to reduce the working body is blocked, the disks are made of larger and smaller diameter and are located on the axis alternately, while the lower points of the disks of larger diameter are located below the blade level of the plowshares the paws, the lower points of the disks of smaller diameter are located above the specified level, and the upper points of the latter are higher than the back of the plowshare back, each disk being mounted on an axis with the possibility of free rotation. 2. Worker body pop. 1, which differs from the fact that on the side edges of the plowshares of the paws there are set obliquely located knives. 3. The working body according to claim 1, in connection with the fact that it is equipped with knot lines attached to the rack, each of which is located behind the disk of smaller diameter. FIG.
