DEVICE FOR SUBSURFACE TILLAGE Russian patent published in 2012 - IPC A01B35/28 A01B35/26 

FIELD: agriculture.

SUBSTANCE: device has a rectangular welded frame with systems of hinging and adjusting the depth of tillage, the latter of which is made in the form of support wheels. On the frame there are two rows of working bodies mounted, containing racks and center hoes. The hoes are mounted from two folding and folding-out semi-hoes with fixation of the semi-hoes position. The racks have a rectangular cross section with a knee at the bottom front part, and a triangular chisel is fixed to it by means of pins. The chisel is equipped with threaded holes and has a beveled bottom part with two tube brackets welded on each side. The brackets are used together with the fastening axes with a thread at the ends and tube brackets welded to the lancet semi-hoes, as hinge mechanisms for semi-hoes. The front part of the rack is made curved; it is coupled with the top plane of the chisel and is equipped with a point. The point is made curved according to the form of the front part of the rack, it is coupled with a chisel and secured with a screw. The point has a width equal to the width of the chisel, and is removable. The fairings are welded to the point at its sides, and fairings-fixers are pivotally attached to them. The hoes are fitted with turners. The turners have the shape of a cylinder and are mounted in windows cut in the semi-hoes with the ability to turn and thrust using the hole and square shaft drilled in the semi-hoes, inserted into the cross square hole made at the end of each agitator.

EFFECT: constructive implementation enables to reduce the energy while tillage due to streamlined working parts and labor consumption for folding and unfolding semi-hoes.
