ASSEMBLAGE STRUCTURE FOR DEEP-PLOWING TINE FOR SOIL PLOWING USE

摘要

PROBLEM TO BE SOLVED: To provide an assemblage structure for a deep-plowing tine for soil plowing use designed to protect the shank body frame of the deep-plowing tine, support the frame by receiving soil pressure on the tip of the tine with the whole shank body and attach/detach or exchange the tip of the tine in an one-touch manner. SOLUTION: The assemblage structure is as follows: A receiving groove is formed on the shank body frame of the deep-plowing tine. At the bottom plate of a shank cover covering the underside of the shank frame, the point of the tip of the tine is projected downward of the shank cover and the rear portion of the tip of the tine is fixed so as to penetrate into the shank cover. A common through hole is formed at a position corresponding to the shank frame and the shank cover with each other. The groove of the shank body is engaged on the rear portion of the tip of the tine integral with the shank cover and the common through hole is engaged with the binding parts of a roll pin and the like.
