Vibration damping device and method for transplanting machine

Abstract

The invention discloses a vibration damping device for a transplanting machine, and relates to the technical field of agricultural machinery. The vibration damping device comprises a base. A vibrationsensor is disposed on the base, and the base is fixedly connected with a buffering cylinder. A spring pipe is fixedly connected with the inner bottom of the buffering cylinder. A piezoelectric pieceis disposed at the bottom of the spring pipe. A cavity is formed in the spring pipe. The two inner sides of the cavity are each fixedly connected with an electrode deposited film and the cavity is filled with electro-rheological fluid. The end, away from the bottom of the buffering cylinder, of the spring pipe is fixedly connected with a piston block. A slide cavity is formed in the piston block.A controller, in cooperation with the vibration amplitude of vibration of the base, controls the intensity of an electric field between the two electrode deposited films in the spring pipe to controlthe yield strength of the electro-rheological fluid under the electric field, thereby controlling the buffering capacity of the spring pipe and effectively realizing a buffer vibration damping effectfor the corresponding vibration amplitude.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a vibration damping device for a transplanting machine and a vibration damping method thereof. Background technique [0002] With the development of agricultural mechanization, agricultural machinery is gradually used for planting and harvesting of crops. Transplanting machines are generally used for planting crops. Existing transplanting machines generally adopt a semi-automatic method, that is, manual sorting Pick the seedlings and put them into the transplanting machine, and the transplanting machine will perform the work of ditching, drilling, seedlings and filling. During the working process of the existing transplanting machine, mechanical vibration is inevitable. These mechanical vibrations come from the normal vibration of the engine and the driving machinery, the mutual vibration between the mechanical connection and the vibration caused by the unevenness ...

AI Technical Summary

Problems solved by technology

[0003] A vibration damping device and a vibration damping method for a transplanting machine proposed by the present invention aim to solve the problem of mechanical vibrations that inevitably occur during the working process of a transplanting machine in the traditional technology, which greatly affects the mechanical parts. service life, and make the staff in a vibrating working environment, which not only affects the work efficiency, but also brings health damage to the staff
