Energy recovery device for vibration of rotating shaft of threshing drum of combine harvester

Abstract

The invention provides an energy recovery device for vibration of a rotating shaft of a threshing drum of a combine harvester, wherein the rotating shaft is supported by a first bearing and comprisesa magnetoelectric hydraulic cylinder, a second bearing and a mounting support; two ends of the rotating shaft respectively penetrate through the mounting support, two ends of the rotating shaft are respectively provided with the second bearing, a plurality of the magnetoelectric hydraulic cylinders are uniformly distributed between an outer ring of the second bearing and the mounting support, a stretching rod of the magnetoelectric hydraulic cylinder is connected with the outer ring of the second bearing, and the magnetoelectric hydraulic cylinders stretch and contract through vibration of therotating shaft and are used for converting energy of vibration of the rotating shaft into electric energy and hydraulic energy. The energy recovery device can convert the vibration energy generated by the rotating shaft into electric energy and hydraulic energy in all directions and finally realize the recovery of excess energy through a hydraulic oil circuit and a rectifier circuit and convert the excess energy into electric energy.

Description

technical field [0001] The invention relates to the field of agricultural machinery and equipment, in particular to an energy recovery device for the vibration of the rotating shaft of a threshing drum of a combine harvester. Background technique [0002] The working environment of the grain combine harvester is harsh and the working conditions are complicated, and it mainly performs grain harvesting and other operations in the field. The threshing drum is the main working part of the grain combine harvester, and the vibration generated during its work has a great impact on the performance of the whole machine in terms of working comfort and reliability. Especially when the threshing drum is entangled with stalks, the threshing drum itself will generate a large dynamic imbalance, which will cause a large vibration of the threshing drum shaft, which will drive the vibration of the frame and make the vibration of the whole machine larger, especially for the grain combination. ...

AI Technical Summary

Problems solved by technology

[0004] The above patents can achieve energy recovery in specific fields and reduce energy loss, but they are not suitable for energy recovery and vibration reduction of the vibration of the threshing drum shaft of the grain combine harvester, because the vibration amplitude of the threshing drum shaft is small, but the frequency is high, and The vibration direction and energy have great randomness, which makes it impossible for the above device to realize energy recovery and vibration reduction for the vibration of the threshing drum shaft of the grain combine harvester
