A vibration damping device and vibration damping method for transplanting machine

Abstract

The invention discloses a vibration damping device for a transplanting machine, relates to the technical field of agricultural machinery, and comprises a base, on which a vibration sensor is installed and a buffer tube is fixedly connected, and the inner bottom of the buffer tube is fixedly connected There is a spring tube, a piezoelectric sheet is installed at the bottom of the spring tube, a cavity is arranged inside the spring tube, electrode deposition films are fixedly connected to both sides of the cavity and the inside is filled with electrorheological fluid, and the spring tube A piston block is fixedly connected to the end away from the bottom of the buffer tube, and a sliding cavity is provided in the piston block. The present invention matches the vibration amplitude of the base vibration through the controller to control the electric field strength between the two electrode deposition films in the spring tube, thereby Control the yield strength of the electrorheological fluid under the electric field, and then control the buffer capacity of the spring tube, effectively achieving better vibration damping effect for 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
