An electromagnetically driven suspended closed threshing device and harvester

Abstract

The invention provides an electromagnetically driven suspension closed-type threshing device and a harvester, including an electromagnetically driven closed-type threshing device, a circuit control group, a magnetic bearing group and a state monitoring and adjusting device; the electromagnetic-driven closed-type threshing device is connected to the circuit control group The electromagnetically driven closed threshing device is suspended by the electromagnetic force of the magnetic bearing group through the rotating shaft, and the circuit control group is connected with the state monitoring and adjusting device. The invention uses the principle of electromagnetic conversion to design the threshing drum as a separate power source, which can realize the threshing drum of the combine harvester as a power generating device, realize its own independent operation and stepless speed regulation through an external power supply, and can be used as the power of other working parts source, reducing energy consumption and improving energy conversion and utilization efficiency. The invention can reduce the vibration of the whole machine due to the imbalance of the threshing cylinder, improve the working efficiency and reliability of the whole machine, and can widely replace the existing closed threshing device of the combine harvester on the market.

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 ...

AI Technical Summary

Problems solved by technology

The invention provides an electromagnetically driven suspension closed type threshing device, which uses the working characteristics of the threshing drum and combines with the principle of electromagnetic conversion to overcome the problems that the threshing device often occurs due to excessive load and insufficient power input during the working process. Problems such as blockage and excessive vibration have achieved the purpose of independent operation of the threshing drum, and can be used as a power source to provide kinetic energy for other working components such as conveying troughs, vibrating screens, and cleaning fans.
