Automatic control stall protection cutting machine for agricultural science and technology

Abstract

The invention relates to the technical field of agricultural cutting machines and discloses an automatic control stall protection cutting machine for agricultural science and technology. The automatic control stall protection cutting machine comprises a cutting shaft, a main rotating shaft is movably connected in the cutting shaft, starting grooves which are uniformly distributed are formed in the main rotating shaft, starting blocks are movably connected in the starting grooves, uniformly-distributed control grooves are formed in the main rotating shaft, control blocks are movably connected in the control grooves, and uniformly-distributed electromagnets are fixedly connected in the main rotating shaft. According to the automatic control stall protection cutting machine for the agricultural science and technology, by means of mutual cooperation of permanent magnets and the electromagnets, the control blocks are driven to overcome the elastic forces of second springs to move and make contact with connection between the main rotating shaft and the cutting shaft, so that the main rotating shaft idles, then by means of the mutual cooperation of the main rotating shaft, the electromagnets and a fixing column, the viscosity of electrorheological fluid in the cutting shaft is increased, the retarding effect of the fixing column on the main rotating shaft is improved, the rotating speed of the main rotating shaft is rapidly reduced, the stall protection function of products is achieved, and the use risk is reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural cutting machines, in particular to a cutting machine with automatic control stall protection for agricultural technology. Background technique [0002] Agricultural production refers to the production activities of growing crops. Including the production of grain, cotton, oil, hemp, silk, tea, sugar, vegetables, tobacco, fruit, medicine, miscellaneous and other crops, in the process of agricultural production, it is often necessary to use cutting machines to process some large crops, but often There will be a situation where the rotation speed of the cutting machine exceeds the normal working range, resulting in increased risk of use, which is not conducive to control, and causes unnecessary trouble to the user. [0003] During the use of the agricultural technology cutting machine, due to the current and voltage fluctuations in the internal circuit of the cutting machine itself, or the unev...
