MULTIFUNCTIONAL COMBINED TILLAGE TOOL Russian patent published in 2011 - IPC A01B35/00 

FIELD: agriculture.

SUBSTANCE: tool comprises frame with several fixed transverse bars. Vertical stands with axes at the ends are mounted in a movable manner on bars. Spherical disks are installed on axes with the possibility of rotation, having controlled attack angle, inclination towards vertical plane and are arranged frontally along grip width. Disks on adjacent transverse bars are arranged with concave or convex sides accordingly in opposite directions. Each disk is displaced relative to adjacent disks towards non-processed earth. Pair brackets with holes are fixed on all transverse bars. Stands of centre (cultivator) hoes or stands of paraploughs may be installed in holes of brackets. Several pairs of holes are arranged in stands of centre (cultivator) hoes, which make it possible to vary depth of soil processing from 50 mm to 300 mm with a pitch of 50 mm. Channel formers are mounted on lower ends of paraplough stands. Length of paraplough stand is such that provides for formation of slot and channel (drain) in soil that has not been processed by previous working element of tool (plough foot) with depth of up to 500 mm, with distances between slots making 400-800 mm. Behind the last transverse bar there is a smaller frame with spring teeth or roller mounted on the frame. Smaller frame is mounted in a movable manner in vertical plane by means of parallelogram mechanisms. Teeth are installed on axis with the possibility to rotate axis, and angle of teeth installation to vertical plane is arranged as controllable by means of traction rod and turn-buckle. Each of proposed working elements may be used separately from each other or in any combination.

EFFECT: improved quality of soil cultivation by damage of plough foot with simultaneous processing of topsoil and improvement of air-water exchange in topsoil.
