agricultural engineering. SUBSTANCE: share has A-hoe secured to tine-seed guide by means of two flush-headed bolts, distributor drawn up to tine from inside of space under A-hoe by nut, corner plates rigidly attached to right and left sides of tine-seed guide, and flexible wall joined to rear lower part of seed guide by rivet. Distributor is fixed in space under A-hoe and has surface defined by two side faces arranged at right angle one with respect to another, and two rear faces intersecting the plane that is extending at an angle of 45 deg to distributor base. Distributor is positioned so that its top is disposed in zone of intensive flow of seeds and fertilizers. Length of distributor is equal to 2/3 of longitudinal size of internal section of seed guide. Broadcast share may be attached to direct seed drills for providing subsoil broadcast sowing of seeds and mineral fertilizers. Such construction of share prevents clogging of seed guide outlet channel. EFFECT: improved sowing quality and increased efficiency by increased width of sown strip of soil and improved uniformity of seed distribution. 2 cl, 7 dwg |
