RECLAMATION FERTILIZER DISTRIBUTOR-SUBSOILER Russian patent published in 2017 - IPC A01B17/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machinery industry. The reclamation fertilizer distributor-subsoiler of plough-layer comprises moldboard bodies fixed to the frame fertilizer dispensers with fertilizer funnels, a high-pressure fan with an air duct. The fan is tightly connected to the fertilizer funnels. In front of the moldboard bodies on racks the unilateral flat hoes-subsoilers are mounted, located at a height below the cutting plane of the moldboard bodies. The racks of the unilateral flat hoes are made knife-like with an inclination of the blade to the horizontal plane against the direction of movement at an angle of 60-65°, providing the soil layer cutting with sliding on the blade. At the rear wall of the racks the fertilizer funnels are located, connected with fertilizer distributors mounted under the flat hoes. The fertilizer funnels are tightly connected to the fertilizer distributing units and the pressure cavity of the fan. The fertilizer distributing units are made screw and mounted in the bottom of the hoppers for fertilizers. The hoppers have tight covering lids. Over the hoppers a tank for livestock wastes with reel dispensers is mounted. The drive of the fertilizer dispensers and reel dispensers is made from the PTO shaft of the tractor through a gearbox. The fan drive is made from the hydraulic motor.

EFFECT: decrease in the traction resistance of the tool and the fertilizer saturation of subsurface horizon is provided.
