CHOPPER SPREADER FOR SOLID ORGANIC MANURE Russian patent published in 2016 - IPC A01C3/06 A01C15/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machine building, in particular, machines for milling and surface application of solid organic fertilisers. Milling and spreading machine comprises chassis, loading hopper, vertically installed disks with guide flares, and drive mechanisms of actuators. Spreading discs are made milling, with disk base, on side surface of which replaceable pyramidal milling teeth are fixed along helical lines of multiple screw. Spreading discs are installed in casing, lower front part of which at side of loading hopper has feeder window coupled with feed conveyor, rotation of spreading discs is counterwise. Lower part of casing under spreading discs is arranged as latticed and has guide flares. In lower part under spreading discs there is milling and spreading drum made in revolution paraboloid form. Drive of spreading discs is made from hydraulic motor with reduction gear, with two output shafts of different rotation direction. Drive of milling and spreading drum is made from conveyor drive shaft via reduction gear.

EFFECT: uniform distribution of milled fertilisers across field surface is provided by this design.
