SEEDING UNIT FOR SINGLE-SEED-HOLE SOWING OF GERMINATED SEEDS OF HOED, VEGETABLE AND GOURDS CROPS

摘要

FIELD: agriculture.SUBSTANCE: sowing unit for single-seed-hole sowing of germinated seeds of hoed, vegetable and gourds crops comprises a cellular driving dick mounted at an angle to the horizontal plane. The cells are made according to the shape and size of the seeds of the crop sown and are placed on the peripheral part of the disk in groups. The number of cells in the group is equal to the number of seeds that sown in the hole. The cells in the group are placed in peripheral row with minimal spacing between them. The cells of the second row are placed near the jumpers of the peripheral row with placement of the cell centres near the jumpers of the peripheral row. The cellular driving disk on the outer edge has a ring gear of the drive of the brush reflector of extra seeds. The brush reflector is covered with the casing and is made in the form of a truncated cone. The coning angle of the cone corresponds to the angle of slope of the cellular driving disk of 40-45°. The drive of the brush reflector is made of a cylindrical gear reducer fixed to the side wall of the seed box and covered with the casing. The brush reflector has a counter rotation to the cellular driving disk. Over the cellular driving disk using a bolt a cone-seed guide is mounted, coupled with cells of the cellular driving disk. The cellular driving disk rests on a tray with sowing window in the upper part, coupled with the seed duct. The seed box is secured to the tray by means of clamps. The drive of the cellular driving disk is performed through the bevel gear. The seeding unit is attached to a section of the drill with a bracket.EFFECT: use of invention enables to provide more compact holes for seeds, to improve the accuracy of sowing without damaging the seeds and their seedlings.2 dwg
