Abstract

The invention relates to an agricultural machinery industry, namely to parts of the crop to serve for directing and laying the seeds in the soil. The aim of the invention is the expansion of technological capabilities by ensuring the sowing of seeds in soil of different hardness without prior treatment. The opener contains polozovidny knife 1, cheeks 3 and bed seal 2. A knife-shaped knife 4 is attached to the knife 1 height-adjustable knife 4. Knife 4 is attached to knife 1 by means of bolt fastening 5 and has oblong holes 6. When working on solid soil soils, the knife 4 due to the acute angle of entry into the soil provides the depth of the opener to the required depth and high-quality seed placement. 5 il.

3 U9 The invention relates to agricultural machinery, namely, parts, sprouts, which serve to guide and place the seeds in the soil. The purpose of the invention is to expand the technological capabilities by providing sowing of seeds in soil of different hardness without prior treatment,

FIG. 1 shows a polozovidny coulter, side view; in fig. 2 - the same, top view; 3 - chisel-shaped knife, side view; in fig. 4 - the same, top view; in fig. 5 - polo: call opener With a raised chisel knife,

The opener contains a polosoid knife 1, a knife sealer 2, cheeks 3 and a chisel-shaped knife 4 attached to the skid-shaped knife by means of a bolted joint 5. In order to ensure the height adjustment of the chisel-shaped knife 4, it is made with oblong holes 6 that are used to there are bolts of connection 5. Knife 4 is made of l with an internal cavity 7, which includes a knife-like knife.i о

The opener works as follows.

Ca of dense, sourd, stubble soils. The chisel-shaped knife 4 is set so that the polo-shaped knife 1 is completely in the cavity 7 of the chisel-shaped knife 4, and is fastened by means of a bolt joint 5 ". plane passing through the line AB (figo 1), the chisel-shaped knife 4 cleaves the soil under the plant residues, shifts it up, forward and to the sides of the soil, the coulter acts as a deepening force. On less dense soils, to ensure the coulter has the required density of the bottom and the furrow walls, the chisel-shaped knife 4 with elongated holes 6 moves upward by the required value h. In this case, the lower part of the ved of the blade 1 emerges from the cavity 7 of the chisel-shaped knife 4 and, during operation, additionally seals the bottom and walls of the furrow formed by the vomer (Fig. 5),

The amount of movement h of the chisel-shaped knife 4 up depends on the degree of necessary additional sealing of the bottom and walls of the furrow. If necessary, the chisel-shaped knife 4 can be dismantled.
