ENERGY SAVING TRAILED SOWING COMPLEX Russian patent published in 2014 - IPC A01C7/00 A01B49/06 

FIELD: agriculture.

SUBSTANCE: offered invention relates to devices for sowing of grain, leguminous and other agricultural crops. The sowing complex contains the tractor-drawn two-section bin 2 on two support wheels 3 located on the frame 1. Behind the bin the folding shoe-type frame 4 with adjustable forward 5 and back 6 supporting raning together wheels is located. Under the bin sections the batchers 20 are installed. On the side of the bin the load screw conveyor 15 folded in travelling position is fixed with a receiving hopper 16 for seeds or fertilizings. In front of the screw conveyor the centrifugal blower 13 with the drive 14 is located. Shoe-type frame 4 is equipped with hydraulics, air distributing collectors 11 and corrugated pneumohoses 12, connected with the pneumotransport tube 21, which, in turn, connects the batchers 20. Between the wheels 5 and 6 in the chess order spring-loaded opening plows 7 are located, and behind opening plows - three-row spring harrows. The spiral housing of the ventilator 13 is fixed on the motor 14 from the side of the output end of its crank shaft, on which the impeller of the ventilator 13 is installed. The batchers 20 are rotated through electroclutch by the support wheel 3 according to the sequence: chain transmission - electroclutch - chain transmission - seeding transmission box - batchers. Opening plows 7, moving along line traces of support wheels 3 and front support wheels of the shoe-type frame 4, compared with others opening plows of the complex are installed lower by the value Δh=0,020…0,040 m.

EFFECT: invention provides the decreased metal consumption of the design and ensures improved quality of seeds application into soil.
