Cultivators lateral flow prevention ring of beta

摘要

PROBLEM TO BE SOLVED: To prevent the development of cross flow of a cultivator in working on a sloped ground surface of a field.;SOLUTION: This cultivator is constituted by a cross flow-preventing wheel rolling by biting into the surface of the ground with a circumferential projecting width obtained by joining one or two of traveling wheels linked with an oblong supporting bar of the cultivator with a wheel rolling on the surface of a ground and a blade-type disc having the circumferential projecting width extending to the outside of the outer circumference of the wheel as one unit. Preferably, the cross flow-preventing wheel is obtained by nipping the blade-type disc having a larger diameter than those of recessed wheels, between the left and right recessed wheels concentrically, and positioning counter surfaces for tightening bosses in a central recess at more inside than the tip end of the outer circumference of the recessed wheels counter to each other as mediated by the blade-type disc.;COPYRIGHT: (C)2008,JPO&INPIT
