TRACE-RIPPER OF TRACTOR Russian patent published in 2014 - IPC A01B37/00 

FIELD: agriculture.

SUBSTANCE: trace-ripper comprises the side sections attached to the cross bar. Each section comprises rippers with blade racks, arranged in two rows parallel to the cross bar. The rippers of the rear row are provided with tabs and mounted staggered relative to the front row rippers. Behind the rippers of the rear row a drive battery of tooth disks if mounted with the location of the disk teeth opposite the middles of the intervals between the adjacent rippers of the front and rear rows. The racks of the rippers are made inclined relative to the vertical along the path of the unit at an angle of 20°-30°. At the rear edge of the rippers of the rear row the tabs are mounted horizontally in two layers with the location of ends of the tabs on the same vertical, which coincides with the axis of symmetry mounted above the drive battery of tooth disks. Behind the battery of tooth disks on the semi-frames rigidly connected to the cross bar, with the ability of changing the depth of the unit the subsurface cultivators are mounted. The subsurface cultivators are made in the form of arrow-shaped flat blades. Behind each of the subsurface cultivators a rod-bladed roller with front rod concave surface of the blades is mounted.

EFFECT: improving the quality of treatment of compacted soil in the tractor trace.
