Electromagnetic driven suspension closed threshing device and harvesting machine

Abstract

The invention provides an electromagnetic driven suspension closed threshing device and a harvesting machine. The device comprises an electromagnetic driven closed threshing device, a circuit regulation and control group, a magnetic bearing group and a state monitoring and adjusting device, wherein the electromagnetic driven closed threshing device is connected with the circuit regulation and control group; the electromagnetic driven closed threshing device is suspended through electromagnetic power of the circuit regulation and control group through a rotating shaft; and the circuit regulation and control group is connected with the state monitoring and adjusting device. Through an electromagnetic conversion principle, a threshing cylinder is designed as an independent power source, a threshing cylinder of a combined harvester can be used as a power generation device, self independent operation and stepless speed variation of the threshing cylinder self can be achieved through an external power supply, and the threshing cylinder can be also used as a power source of other working components, so that the energy consumption can be reduced, and the energy conversion and utilization efficiency can be improved. By adopting the device, vibration of a whole machine, which is caused by unbalance of a threshing cylinder, can be reduced, the working efficiency and reliability of the whole machine can be improved, and a conventional closed threshing device of a combined harvester in the market can be massively replaced.

Description

technical field [0001] The invention belongs to the field of structural design and manufacture of a grain combine harvester threshing device, and in particular relates to an electromagnetically driven suspended closed type threshing device and a harvester. Background technique [0002] The power source of the combine harvester threshing drum is generally powered by the engine, but because there are a lot of working parts on the combine harvester and the energy consumption is relatively large. The threshing drum, as the most energy-consuming part of the various working parts of the combine harvester, often has problems such as blockage and excessive vibration due to problems such as excessive load and insufficient power input during the working process. The engine power required by the complete machine of the combine harvester is very large, and it is prone to failure when working in the field, resulting in a reduction in the reliability of the complete machine. Because the ...
