DEVICE FOR TILLING IN PERENNIAL PLANT ROWS

摘要

FIELD: agriculture. ^ SUBSTANCE: device comprises a carriage, retractable operating element, mechanism of its retraction, tracking control mechanism for the retractable operating element. The retraction mechanism for the operating element is of parallelogram type with power hydraulic cylinder. The traction mechanism is fitted with a hydraulic control valve and a sensor in the form of a copying probe which are set on the one of the moving links - connecting rod of the parallelogram mechanism. The traction mechanism comprises also a unit for the individual adjustment of initial and final position of the probe and the operating element. The individual adjustment unit is made as a lever with a pivot pin set on the connecting rod of the parallelogram mechanism. One of the lever arms is of U-shape with adjustable stops which are placed on both sides of the stop mounted on the crankshaft of the parallelogram mechanism. ^ EFFECT: such design provides for the application of the device in various operation conditions. ^ 1 dwg
