Description

one

The invention relates to machines and implements for soil fertilization and seed.

Working bodies are known that have guides and reflectors with curvilinear wings with concavity facing the flow of material to be sown 1.

Known working bodies, including a flat-cutting paw, and a guide and distributor with a curved working surface having a horizontal edge and a front wall 2.

A disadvantage of the known working bodies is that the shape of the reflecting surface of the distributors does not ensure uniform distribution of the sown material across the width of the working body. Consequently, the use of known devices to evenly distribute seeds and fertilizers over a width of about 1.5 m is impossible, and with a capture width of up to 1.1 m, very precise adjustment of the air flow parameters necessary for additional acceleration of particles of the sown material is required.

The aim of the invention is to improve the uniformity of distribution of the sown material across the width of the working body.

This goal is achieved by the fact that the distributor is made in the form of a paraboloid, with the upper point of the parabolic generator located on the horizontal edge, and each tangent to the parabola at the point of intersection with the edge has a constant angle of a-inclination to the vertical, while the projection on the horizontal plane divides into proportional parts of the reflector edge and each of the half widths of the working body, besides the front wall of the distributor and the front wall of the guide are made in the form of a dihedral wedge, the edge of which is Directed to the side of the flat cutting foot.

FIG. 1 shows the proposed working body, top view; in fig. 2 - the same, rear view.

The working body consists of a guide 1, mounted behind the stand 2 of the flat-cutter 3. In the lower part of the guide, a distributor 4 is installed, made in the form of a paraboloid with an edge 5. Particles of the material being sown, reflected from the distributor, move along a trajectory of m 6.

The work of the working body is carried out as follows. When the machine moves, the flat cutter 3 performs soilless tillage to a predetermined depth. At the same time, the particles of the material being sown from the bunker with the dosing unit installed on the gun frame, through the acceleration device, follow the guide 1 installed behind the stand 2, and are reflected from the surface moving along the trajectory of m 6 and evenly distributed across the entire width of the working body in the sublap space.

Claims (2)

1. A working body for subsurface seed sowing of seeds and fertilizers, including a flat-cutting paw, a guide and a distributor with a curvilinear working surface having a horizontal edge and a front wall, characterized in that in order to increase the uniformity of distribution of the sown material across the working width of the working body, the distributor is made in the form of a paraboloid, with the top point of the parabola generatrix located on the horizontal edge, each tangent to the parabola at the point of intersection with the edge t is a constant angle of inclination to the vertical, while the projection onto the horizontal plane divides the reflector edge and each of the halves into proportional parts the width of the working body, in addition, the front wall is made in the form of a dihedral wedge, the edge of which is turned in the direction of the flat-cutting paw. 2. The working body of claim 1 is also distinguished by the fact that the front wall of the guide is made in the form of a dihedral wedge. Sources of information taken into account in the examination 1.
