(54) BREEDER FOR SUBMERGED CLEANING CROPS

one

FIELD OF THE INVENTION The invention relates to agricultural machinery, mainly to coulters for subsurface spreading of grain and other bulk materials.

The opener for subsurface spreading is known, including a paw connected to a hollow stand, under which is a conical scatterer of loose materials, equipped with a disk with spiral vanes and made with an autonomous rotational drive mechanism.

The disadvantage of the opener is that the seeds are unevenly distributed over the area and not well enough. The bed for the seeds is formed and compacted. In addition, the installation of an autonomous drive increases energy costs.

The purpose of the invention is to improve seed placement and reduce energy consumption, as well as ensuring: independent rotation of the discs and compaction of the bed with opposite uncovered segments of the tapered discs, reduction of combing and cover of the seed with soil in the zone of passage of the rack-seed wire.

This goal is achieved by the fact that the proposed opener is equipped with a second conical disk with helical blades, the rotating disks 5 are angled to the horizon, their adjacent segments in the paw are located the output channels of the rack wire at a distance of 1/3 of the disk radius from the axis of the opener and 1/5 of the radius from the line connecting the centers of the discs in the direction of movement, while the lid cover 1 is provided with guides and an abutment seal.

On the coulter, the disks are mounted 5 such that the cutting edges of the opposite rear quarters of the disks are lower than all others when the cutting edges of adjacent sectors of the disks are located above the plane passing through the 20 level of the edges of the flanges.

In addition, the spiral vanes of each disk have opposite directions.

Claims (4)

The coulter's paw is provided with directions in the form of half-cones, the axes of which are inclined to the direction of the coulter's movement so that the opposite extreme halves of the cones are parallel to the movement of the coulter, and the adjacent ones facing the center of the coulter are inclined to the rack-sem wire at an angle equal to friction of the soil o- steel. FIG. 1 shows the proposed opener for the subfloat, the general view; in fig. 2 shows section A-A in FIG. 1. The linker has an elongated paw 1 with two guides 2 and 3, two tapered discs 4 and 5, a two-sectional rack-sem wire 6, and an auger 7. The cover of the paw 1 has projections 8 and 9 with openings of the left and right carving. The disks are fastened by means of screw-axles 10 screwed into the slots on the underside with mounted bearings 11. Rotatable disks are tapered with spiral blades 12 of the right and 13 left directions, concavity with the bottom and a bulge on the top of the disks. The coulter works as follows. When the coulter moves, the soil that is in the aisle zone of adjacent covered segments of disks 4 and 5 is cut by the shelves of paw 1 and rises by the plane of the paws to pass behind the opener without contacting the upper planes of adjacent covered segments of disks 4 and 5. The lower planes of the adjacent covered segments of the disks 4 and 5 are also not in contact: with the soil, since they are above the plane formed by the cutting edges of the legs of the paw 1 and the abutment seal 7-. The soil Ba, which is in the zone of passage of the opposite uncovered segments of the disks, is cut by them and compacted by the bottom surface of their rear part, creating a moment of force for rotation of the disks. Seeds coming from the metering unit are fed along the stand-seven to the wire b, divided into two streams and sent in front of the opener on the plane of the adjacent cei-MeHto discs, where one part of them is scattered ahead of the adjacent segments discs 4 and 5 and passes under their lower planes, compacted additionally with an axial seal 7. The other part of the seeds, not reset due to their initial position on the disc, is covered with soil and is carried out by spiral blades 12 and 13 evenly across the width to the back part coulter on compacted bed. Seeds placed on a compacted Bed are covered with loose soil over the width of the opener and in the zone of passage of resistant wires with 6 guides 2 and 3, shifting a part of the soil into the zone of passage of the stitch-seam b, and the removal of soil with rotating disks 4 and 5 Active loosening of the upper layer of the soil is achieved due to the deformation on the surface of the paw 1 from the stand-up of seed grower 6 and guides 2 and 3, and in the passage area of the opposite unprotected segments of the disks 4 and 5 by their action. The opener, actively loosening the top layer of soil, forming and compacting the bed, evenly spreading seed under the upper loosened layer of soil, is a combined working body combining loosening, cutting sulfuric vegetation, sticking, pre-sowing tillage and sowing grain crops, and also sowing fertilizers and their termination. Claim 1. An opener for underground subsurface sowing, including a conical rotating disk with spiral blades, a rack-sem wire and a cultivator-type paw, so that, in order to improve seed embedding and reduce energy consumption, the stab is equipped with a second conical disk with spiral blades, the rotating disks being located at an angle to the horizon, and above their adjacent segments in the paw are located the high channels of the rack-seven wires at a distance of 1/3 of the disk radius from the opener axis and 1/5 radius from the line, soy the disk centers in the direction of movement, while the foot cover is equipped with guides and pressure seal. 2. The collet of claim 1, in accordance with the fact that, in order to ensure self-rotation of the discs and compaction of the bed with opposite undisguised segments of the tapered discs, the latter are set so that the cutting edges of the opposite rear quarters of the discs mf below all others at the location of the cutting edges of adjacent sectors of the disks above the plane passing along the edges of the legs of the paw. 3. The collet of claim 1, of which the spiral blades of each disc have the opposite direction, 4. The opener of claim 1, characterized in that, in order to reduce ridging and cover the seed with soil in the passage area of the rack-seven wire, the paw is equipped with guide parts in the form of half-cones, the axes of which are inclined to the direction of movement of the opener. forming half of the cones are parallel to the movement of the opener, and adjacent, facing the center of the opener, are inclined to the upright-seven wire at an angle equal to the angle of friction of the soil on steel.
