CULTIVATING TOOL Russian patent published in 1995 - IPC

FIELD: agricultural engineering. SUBSTANCE: tool uses an arched clamp having lower and vertical side sections, and a member for its attachment to the base frame of the potato digger. The clamp side sections are made as cantilevers, and their cutting edges are arranged at an acute angle to the horizontal, whose value increases in length from the bottom to the top. The cutting edges of the clamp lower section are made in the form of conjugated curves forming a pointed tip, their convex camber faces forward. Plates are secured on the side sections, and separating bars are positioned in them in cantilever. The lower section has a subsoil-cultivating surface, whose cross-sections are made in the form of curves with the convex camber facing upwards. The attachment member is a bent hollow post, whose one end has a cross-piece located under the swinging surface and connected to it. The other end of the post has a detachable joint for attachment to the side frame. EFFECT: improved design. 3 cl, 4 dwg
