WORKING BODY OF SUBSOILER-FERTILIZER DISTRIBUTOR Russian patent published in 2017 - IPC A01B49/06 

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machinery industry. The working body of the subsoiler-fertilizer distributor comprises a wedge-shaped rack. On the rear part of the rack a fertilizer funnel is mounted. In the lower part of the rack the plowshares are mounted. In front of the rack a vertical rotary cutter is mounted. Behind the fertilizer funnel, using the brackets fixed to the rack, a loosening drum with teeth is mounted. The drum comprises a hub in the form of truncated cones with their small bases mounted opposing. On the lateral surface of the hub the replaceable teeth are mounted, made in the form of a quadrangular pyramid and located with the ribs in a rotational direction. The teeth are placed on the lateral surface of the hub along the helical lines. On the left half of the drum the helical line has a left-handed direction, while the right half has a right-handed direction. The height of the teeth is equal to the thickness of the soil layer passing down from the plowshares. The front part of the wedge-shaped rack has a cutting-point angle changing in size. In the lower part it is connected to the spanning angle of the plowshares, in the upper part it has a value of 10-15°. Under the plowshares the shoe is fixed to the fertilizer distributor, the trailing edge of which is made below the upper edge of the plowshares. In the upper part of the rack there is a pressure fan for the formation of an air-fertilizer mixture and a fertilizer distributing unit. In the lower part the shoe is mounted to the chisel subsoiler, the front edge of which is made parabolic and recessed below the cutting plane of the plowshares on the value of 0.75 of the depth of the plowshares penetration.

EFFECT: increased productivity and reduced energy costs is provided.
