SOIL RIPPING TOOL Russian patent published in 1997 - IPC

FIELD: agricultural engineering. SUBSTANCE: working tool has tine, shoe with share and ripping members positioned below and above share cutting edge. Shoe and ripping members are mounted on tine. Brackets with supporting platform and shaft are positioned on front side of shoe. Ripping members are fixed on shaft. Each ripping member has inverted upper and lower halves positioned in symmetry relative to shaft. Each ripping member half has two parallel supporting surfaces for contact with bracket. Half positioned below share cutting edge is formed as cutter with curved pointed portion extended in the direction of movement of tool and provided with rear angle at pointed end and cutting edge at its rear side. Half positioned above cutting edge of share is made in the form of straight cutter extending away from direction of movement of tool in the way similar to cutter of lower half on its rear side. Ripping members are mounted so that working parts above and below share may be readily replaced by displacement of ripping member on shaft. EFFECT: increased efficiency, simplified construction and improved quality of soil. 5 cl, 4 dwg
