CASE OF PLOUGH Russian patent published in 1995 - IPC

FIELD: agricultural mechanical engineering. SUBSTANCE: case of the plough has share, mouldboard, shoe, swinging clevis-type cutting tools, which are disposed onto face side of the share and directed into area where mouldboard is brought into contact with share. Case of the plough permits to improve quality of crushing soil when ploughing solid, dried and heavy soils. Swinging clevis-type seam cutters are set during process along the direction of motion of the seam and cut the seam to number of parts being unit more than number of cutting tools mounted onto the case. Height of seam cutters does not excess over 1/3 maximal depth of cutting and angle of cutting is equal or less than angle of friction of soil against the steel. EFFECT: improved efficiency. 2 cl, 2 dwg
