FERTILISING AND RECLAMATION TILLAGE TOOL Russian patent published in 2015 - IPC A01B17/00 

FIELD: agriculture.

SUBSTANCE: tool comprises mouldboard bodies and a fertiliser distributor with fertiliser hoses mounted on the frame, a high-pressure fan with the air-duct. The air-duct is sealingly connected to the fertiliser hoses mounted at the rear side of the mouldboards. In front of each mouldboard body a vertical disc knife is mounted, fixed to the frame with removable brackets. The blade of the disc knife is connected with the toe of the mouldboard body. At the body mouldboard the fertiliser distribution openings are made, placed along the curves of sections of the mouldboard with longitudinal-vertical planes and located in a checkerboard manner. The inlet and outlet walls of the openings are formed on the parabolic curves. The fertiliser distributor comprises a hopper with a sloping bottom, in the lower part of which a cylindrical fertiliser intake device with a spiral guide is placed. The casing of the cylindrical fertiliser intake device in the inner cavity of the hopper has feeding openings which size is 2…3 times greater than the size of the particles of fertiliser or ameliorants. The fertiliser hose outside the hopper has a spiral guide and output windows connected to the fertiliser hoses mounted at the rear side of the mouldboards.

EFFECT: implementation enables to reduce the tractive resistance with simultaneous uniform distribution of fertilisers or ameliorants in the arable layer.
