SOIL DISPERSION COMPLEX ARRANGEMENT Russian patent published in 2010 - IPC A01B77/00 A01B49/02 

FIELD: agriculture.

SUBSTANCE: complex contains a tractor, a frame, a soil receiving element, a slatted apron, and bunkers. The bunkers have corrugated tubing connected with colters. A power unit, a distribution valve of a pneumatic system of the tractor with air hoses are provided to enable the complex traveling over a field and supplying soil into the colters. The sequential working operations are performed by a separating mechanism mounted behind the slatted apron supplying soil from the soil receiving element. The separating mechanism comprises a sieve box with mesh diametre 1 mm. The sieve reciprocates by a crank mechanism to separate two fractions of the supplied soil: fine fraction of particle diametre less than 1 mm, and coarse fraction of particle diametre more than 1 mm. The coarse soil fraction is discharged from the separating mechanism on the surface of the field under cultivation. The sifted fine soil fraction is supplied from the separating mechanism on a horizontal auger conveyor following the separating mechanism. The horizontal auger conveyor transports the soil onto a vertical auger conveyor used as a feeder to be delivered in a disperser. The disperser represents a dismembrator apparatus.

EFFECT: reduced power consumption of soil dispersion and higher processing efficiency of hydro-physical improvement of fine grain soils.
