Abstract

The invention discloses a springback device and a working tool lifting device for agricultural machinery. The springback device comprises a shell, a reciprocating pressing part and an elastic part, the shell is provided with a first cavity, the reciprocating pressing part is movably installed in the first cavity, the elastic part is arranged in the first cavity, and is positioned between the reciprocating pressing part and the inner wall of the shell, so that the elastic part can be extruded to generate compressive deformation along with the movement of the reciprocating pressing part; and when the external force for pushing the reciprocating pressing part is reduced, the elastic part returns to the initial state to drive the reciprocating pressing part to move.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a rebound device and a lifting device for working implements for agricultural machinery. Background technique [0002] Agricultural machines are generally equipped with work implements for work. The lifting arm is installed on the agricultural machinery, and the working tools for agricultural operations are installed on the lifting arm. At present, the agricultural machinery adopts the method of mechanical force-position feedback combined with the driver's manual manipulation of the operating handle. The manual manipulation of the operating handle controls the longitudinal displacement of the distributor valve stem. , and then control the oil pressure of the hydraulic oil in the distributor, so as to control the agricultural machinery hydraulic cylinder, and then control the operation tools to rise, fall, neutral and other actions. [0003] Agricultural machinery uses mecha...
