SUSPENSION OF WORKING MEMBERS OF CULTIVATOR Russian patent published in 2016 - IPC A01B61/04 A01B63/24 A01B35/22 A01B39/22 

FIELD: agriculture.

SUBSTANCE: invention relates to devices for connection of tillers with their frame. Suspension of working members of cultivator comprises vertical swinging lever with attached to its lower end of carrier with working tool holder. Suspension comprises bar with spring. Spring bottom end is connected to rod, and upper end of spring is limited by thrust. Upper part of swinging lever is articulated with upper back part of bar frame. Hinge joint of swinging lever with frame is shifted backward relative to lower hinge, linking swinging lever with dog of working member in initial position by value where r is length of swinging lever in meters m, c is tolerable vertical movement of dog in meters, c≈0.01 m. Dog of working member is located horizontally. Lower end of rod is shifted forward relative to upper end by a value, which also does not exceed S. Dog of working member is connected with bracket fixed in lower front part of cultivator frame by means of one or two symmetrically set tension springs with mechanisms for adjustment of their tension. In upper part of suspension of working members between stopper and spring rod there is a pressing plate with slots for rods, which rests against screw regulators arranged on stop.

EFFECT: such design solution provides simplified design of working members of cultivator and low power consumption of soil treatment.
