摘要：
FIELD: agriculture.SUBSTANCE: wide-cut spring harrow comprises parallelogram mechanisms. On the upper bars of the parallelogram mechanisms through the suspensions the lower bars of the parallelogram mechanisms are suspended. The rear suspensions are made adjustable and have a system of openings and a stop groove. The mobility of the lower bars with respect to the upper bars is implemented by the springs. On the upper bars the fingers are fixedly mounted. The fingers interact with the grooves located in the rear adjustment suspensions for limiting the end position of the springs. The intermediate mobility of the lower bars with respect to the upper bars is limited by fingers-limiters. The fingers-limiters are mounted in one openings of the system pairs, of rear adjustment suspensions. The angle of inclination of the spring teeth to the surface of the field is adjusted by displacement of fastening of the adjusting plate by the bolt to the lower part of the lever. The lever is aligned with the adjustment knob of installation angle of the spring teeth through the adjustment plate. The second end of the adjustment plate is movably mounted in the upper part of the lever of the adjacent tube, forming a hard triangle.EFFECT: increase in uniformity of treatment of fields in depth while harrowing, simplification of the procedure of adjustment of the working bodies, and simplification of the harrow design.3 dwgИзобретение относится к области сельскохозяйственного машиностроения, в частности к почвообрабатывающим орудиям для поверхностной обработки почвы.
