摘要：
FIELD: agriculture.SUBSTANCE: ploughshare comprises a body (1), two discs (2) installed at an angle to each other on the body, a seed guide (3) and a ripper (4). The guide (3) and the ripper (4) are made as a whole and of a closed type, are located between the ploughshare discs (2) and installed in the rear part of the ploughshare and below the funnel (5) of the filler (6) of the ploughshare body (1). The longitudinal-vertical symmetry plane of the guide (3), the ripper (4) and the funnel (5) coincides with the longitudinal-vertical symmetry plane of the ploughshare. The guide (3) and the ripper (4) are made of a pipe of round section. A bell (7) tightly put on the funnel (5) is fixed to the front part of the guide (3). The guide (3) is directed to the side opposite to the ploughshare movement. The symmetry axis of the guide (3) is tilted in the movement direction of the ploughshare relative to the horizontal by an angle of 60 degrees. The gaps between the ploughshare discs (2) and the lateral surfaces of the guide (3), measured near the cutting edges of the rear part of the ploughshare discs, are equal to at least 10 mm on each side of the lateral surface of the guide (3). The ripper (4) is located vertically and at the same time is rigidly attached with its upper part to the rear part of the guide (3). The outlet opening (9) of the lower bent part (8) of the ripper (4) does not extend beyond the transverse-vertical plane. The base of the lower bent part (8) of the ripper (4) is made in the form of a hollow curved wedge (10). Below the supporting face of the hollow curved wedge (10), a heel with a horizontally-made bottom is rigidly attached. The rear part of the heel (11) with the bottom coincides with the plane of the outlet opening (9) of the lower bent part (8) of the ripper. In the front part of the heel, from below the supporting face of the hollow curved wedge, an inclined oval rib (13) is installed. The inclined oval rib (13) is interfaced with the supporti
