PLOUGH-FERTILISER Russian patent published in 2010 - IPC A01B17/00 A01B49/06 

FIELD: agriculture.

SUBSTANCE: plough comprises frame-fixed mouldboard units and fertiliser dispensers with fertiliser hoses. Fertiliser dispensers are equipped with air system for pressure supply of fertilisers. System of fertiliser supply comprises high-pressure fan with drive from hydraulic motor and air duct. Air duct has tappings to each fertiliser dispenser. Fertiliser hoses are installed behind stands of mouldboard units and are tightly fixed to slots arranged between ploughshare and mouldboard of units and directed along tangent to ploughshare. Fertiliser hoses are matched with slots along circumference arc. Fertiliser dispenser comprises tightly sealed cylindrical jar, on bottom of which there is a disk-batcher arranged. Disk-batcher represents a rotor, blades of which are arranged along logarithmic spiral. Disk-batcher is arranged as replaceable, and thickness of disk-batcher is selected depending on norm of fertiliser application. In cover of cylindrical jar there is a nozzle provided for connection to air duct tapping. Nozzle is connected by channel in cylindrical jar with dispensing window. Dispensing window is arranged in jar bottom. Front wall of channel has limiter of fertiliser layer height. There is an agitator provided on driving shaft of fertiliser dispenser.
