COMBINED TILLAGE WORKING ELEMENT Russian patent published in 2014 - IPC A01B33/00 

FIELD: agriculture.

SUBSTANCE: working element comprises a rod roller with alternating rods of square section and bearing units. The bearing units are attached to the rear links of the four-link parallelogram suspension. Under the roller a flat tooth with racks is mounted, which have the ability to move up and down, back and forth. The roller rods form a rhomb-shaped surface by alternating the rods mounted in parallel to the axis of the roller and at an angle to it. To the outer front edges of parallel rods the needles are attached chequer-wise. Part of the needles enters into the inner space of the roller rod, and the part goes outwards. The passage of the needles outwards constitutes 0.4-0.5 of the passage inside the space of the rod roller. The angle of crumbling of the flat tooth is 5-7°.

EFFECT: improving reliability of the machine operation and the degree of soil crumbling, increasing productivity and reduction of materials consumption.
