APPARATUS FOR INTER-ROW TREATMENT OF TILLED CROPS Russian patent published in 2010 - IPC A01B39/00 A01B39/14 

FIELD: agriculture.

SUBSTANCE: apparatus comprises wheel tractor, having synchronous drive for power take-off shaft. Cultivator is joined to tractor by means of hitch mechanism. Cultivator has frame, to which sections with working elements are attached. In front of each working element there is a disk arranged with toothed rim. Disk is rigidly fixed on horizontal shaft, which rests on bearings of support bracket. Bracket is fixed on frame. Transmission mechanism is mounted on frame to transfer torque from power takeoff shaft to disk shaft and to maintain the following dependence:

where ω_d is angular speed of disk shaft; r_d is radius of disk; ω_w is angular speed of master tractor wheel; r_w is radius of master tractor wheel. On sides of disk on shaft there are rollers freely installed, diametre of which is less than disk diametre 1.8…2.1 times.

EFFECT: such structural design will make it possible to improve linearity of tool motion.
