(54J WORKING BODY FOR UNDERGROUND BANDING OF SEEDS AND FERTILIZERS

The invention relates to agriculture, namely, to working bodies for the subsurface spreading of seeds and fertilizers, and is intended for sowing fertilizers and seeds to the bottom of the furrow in the submaking space of the deep-rippers - flat corz. The working body for ground subsurface seeding of seeds and fertilizers is izvosten, including a guide made in the form of paired tubing, installed behind a flat-cutter stand, and reflectors with curved wings attached at the bottom of the guide cutter. water l. However, a known working body is characterized by an insufficient uniform distribution of seeds and fertilizers in the middle part of the furrow, since the bases on the mass of seeds and fertilizers coming from the feed lines on curved wings of the reflector are scattered around the edge of the furrow. Also known is a working device for subsurface spreading of seeds and fertilizers, including a guide and a reflector with curviline wings 2 installed under the guide. hemispherical shape. In addition, it is characterized by unreliability in operation due to clogging of the reflector with soil and crop residues. The purpose of the invention is to increase the reliability of the work of the working body for the subsoil spread sowing of seeds and fertilizers. This goal is achieved by the fact that in a known working body for

ground subsurface seeding of seeds and fertilizers, including a directionfenb and a reflector with curviline wings installed under the guide, curvilinear reflector bores are parabolic and truncated by vertical planes at an angle to the plane of symmetry of the working body and forming a dihedral angle, the top of which is directed to the side rear end reflector.

FIG. Figure 1 shows the working device for the subsurface distributed seeding of seeds and fertilizers, side view, partial section; FIG. 2 shows the same, top view; FIG. 3 shows the working body reflector for the subterranean spreading of seeds and fertilizers, rear view; FIG. 4, the same, top view. The body for the subsoil seed seedling The fertilizer contains a guide 1 and a reflector 2 with curved wings mounted under the guide 1. The curved wings of the reflector 2 are parabolic in shape and truncated vertically and PLANE SPEEDS located at an angle to the plane of symmetry of the working body and forming a dihedral angle, the apex of which is directed toward the back end of the reflector 2. The elastic wall 4 is attached to it. The working device guide 1 for the subsurface spreading of seeds and fertilizers is attached to the opener 5 of the opener, and its reflector 2 is placed in the space under the cultivator 6 th paw opener between vertical cheeks 7,

The device operates as follows.

When the coulter moves, the material to be sown through the sender 1 and the funnel 3 enters the reflector 2 and, from the curved wings of the reflector 2, the stack enters the bottom of the furrow formed by the opener. Since the curved reflectors 2 are parabolic in shape and truncated by vertical planes, the

at an angle to the plane of symmetry of the working body, and the dihedral angle formed by the vertical planes is located vertix towards the back end of the reflector, 2, t, e. against the direction of movement of the coulter, the material being sown, the stack with curvilinear reflections of the reflector 2, is evenly distributed along the bottom of the furrow in the sub-lap space of the coulter. With the further movement of the collar, the bottom of the furrow with the material spun out of it becomes fixed by a layer of soil that converges from the surface of the cultivator paw 6 of the opener. The elastic wall 4 and the vertical cheeks 7 of the opener ensure the flow of sown material directly to the curved wings of the reflector 2, completely excluding the request for sowing material in front of the reflector 2 and from its sides,

The proposed design of the working body for subsoil sowing of seeds and fertilizers ensures its reliable operation, which, in turn, contributes to increasing the yield of agricultural crops.
