FIELD: agriculture.
SUBSTANCE: invention relates to agricultural machinery industry. The machine comprises ploughshares, high speed, main and cascade chain elevators, running and supporting wheels, a screw mechanism for adjusting the depth of digging of tuberiferous layer, elliptical sprockets, and the intensifier of soil separation, mounted over them in the direction of the heap motion. The ploughshares are fastened to the connecting rods pivotally mounted on the eccentrics. The intensifier is made in the form of a drive shaft with flanges on which the rods are mounted on a screw line. The intensifier is mounted with the ability of changing the distance between it and the chain elevator. The rods are made with a cross section in the form of an oval and located at an angle to its axis. The vertices of the oval are located on a cylindrical surface of the intensifier. The working surfaces of each rod are made of material with high coefficient of friction, for example rubber.
EFFECT: intensive separation of soil is provided.
