TILLAGE UNIT (VERSIONS) Russian patent published in 2012 - IPC A01B33/00 

FIELD: agriculture.

SUBSTANCE: unit for a first embodiment comprises a frame with support wheels attached to the tractor and the propeller sections mounted on it in the form of rotating working parts. Each section of propellers has a drive shaft and comprises an independent mechanism to regulate the depth of processing. The drive of propellers is made from the tractor PTO. The propellers are installed on the frame sequentially. The shafts of the front and rear sections of the propellers are kinematically connected to each other. In the kinematic chain between the front and rear sections of the propellers the mechanism of change of gearing ratio and direction of rotation is installed. According to the second version the machine comprises a frame with supporting wheels and the sections of the propellers in the form of rotating working parts attached on it. Each section of propellers has a drive shaft and comprises an independent mechanism to regulate the depth of processing. The frame of the unit is made in the form of two articulated half-frames with the mechanism of change in their relative position in the horizontal plane. On each half-frame a section of propellers is installed. Propeller shafts are kinematically linked to the engine. The sections of propellers are interconnected by the mechanism of change of the gearing ratio and direction of rotation.

EFFECT: constructive implementation of the units will enable to achieve maximum performance with minimum power consumption and the tillage quality meeting the agro-technical requirements of different physico-mechanical composition and condition.
