AMELIORATIVE TILLAGE TOOL Russian patent published in 2015 - IPC A01B17/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machinery industry. The tool comprises mouldboard bodies mounted on the frame, fertiliser distributing machines, high-pressure fan with the air duct. The air duct is pressure-tight connected to fertiliser tubes fixed to the rear wall of the mouldboards and radially connected with the gap between the ploughshare and the mouldboard at a tangent to the surface of the mouldboard. On the outer surface of the ploughshare in front of the gap there are chisel protrusions, which extension over the gap is made in the form of teeth. The fan drive is made from the motor. On the working surface of the mouldboards the chisel rollers are made, fixed to the rear wall of the mouldboard and protruding above the mouldboard working surface. The fertiliser distributing machines are made reel. The length of the reel is equal to the width of the fertiliser tube. The reel cavities are formed in a helical line. The drive of the fertiliser distributing machines is made by the PTO shaft through the gearbox.

EFFECT: constructive implementation enables to provide even distribution of fertiliser and ameliorants throughout the depth of the arable layer, and also to reduce the tractive resistance during processing, and to improve yields.
