TILLING MACHINE Russian patent published in 2013 - IPC A01B33/10 A01B71/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machinery industry, namely, to tilling machines. The tilling machine comprises a frame with a hitch device and the support wheels, two symmetrically mounted rotating working bodies with elliptical discs, hydraulically driven by hydraulic motors mounted inside the hollow drum on a fixed support in the form of a channel with short shelves. On the shaft of the hydraulic motor a drive pinion is mounted engaged with toothed wheel with internal teeth rigidly connected to the drum. In the outer end of the drum is made with a bearing assembly is made with a trunnion welded to the support. The inner end of the drum is closed by a motionless disc. Along the perimeter of the disc the balls (rollers) are placed. The hydraulic cylinder and rods with cardan hinges or loops of the rope set the angle of attack of the working bodies. The hydraulic motor with dual pulley with the ropes and hydraulic hitch system turn the working bodies to the transport position.

EFFECT: constructive solution is aimed at improving working bodies drive, enables to change angle of attack during the movement of the device, and is aimed at reducing width of the tilling machine in transport position.
