COMBINED AGGREGATE FOR TILLING AND SOWING Russian patent published in 2009 - IPC A01B49/06 

FIELD: agriculture.

SUBSTANCE: aggregate contains installed on frame ridgers, box for mineral fertilisers, compactors for compaction of combs, seed-box with ploughshares, bearing-drive wheels, electrical control assembly. Ridger is implemented as composite: fore part and waste part with variable curvature of work surface. Top back one third of waste surface allows variable rounded radius, equal to 920-780 mm. To back waste parts of ridger there are rigidly fixed extension plates of length 10-15 cm, and its side edges repeat curvature of waste surface. Compactors for compaction of combs are implemented as compound from two equal parts in the form of screws with varied pitch and opposite direction of coils from butt end to the middle of compactor. At vertexes of screw coils there are rigidly fixed teeth. Side surfaces of screws are implemented in the form of arcs, center of circle of which are located at one line, coincide with central axis of upright, on which there are fixed compactors with ability of rotation. Control assembly is electrically connected to solidity sensors of soil, installed on upright of applicator and on durometre, located behind planting apparatus.

EFFECT: improving of tilling, keeping of combs' profile.
