Due to the excessive current of the coal mining scraper conveyor and the long start-up time, the motor will be burned. When the current is too large, the voltage is fast, the roller and the adhesive tape form a slip, forming a conflict, which causes the conveyor belt to wear quickly and affect the service life of the belt. Therefore, under the heavy load of the coal mining scraper conveyor, the torque can be started at low speed, stable, and the dynamic stress can be reduced without charging. If the acceleration of the coal mining scraper conveyor is too large, it will cause the material to fall. When the coal mining scraper conveyor is used in combination, the front is equipped with a loader, and the rear is equipped with an unloader or conveyor belt machine.
Or the capacity of the coal mining scraper conveyor is too large. When a heavy load occurs, the motor will be burned. This requires a speed control device. When the load is high, the material can be run quickly. When you are young you may want to run at low speed to complete the full load. During the operation of the coal mining scraper conveyor, many obstacles such as configuration obstacles, safety, and material particles should be monitored.
Through the comparison of the use of a surface, it was found that the wear of the casting groove in the middle of the coal mining scraper conveyor was very good Differently, there is severe wear and tear.
The results show that the middle groove of the coal mining scraper conveyor is cast as much as possible, so that the middle plate of the middle groove can be oriented along the running direction of the scraper and the total number of wave patterns helps reduce the scraper in the coal mining scraper conveyor. The contact area of the middle plate significantly reduces the friction resistance of the blade and extends its service life.
