The working surface of a scraper conveyor fluctuates greatly during operation. In actual underground production, the amount of coal produced fluctuates with the changing conditions of the working surface. This results in complex and variable loads on the conveyor, and the scraper chain must withstand enormous, repetitive impact loads. These repetitive impact loads can easily lead to fatigue, weld cracking, and even chain breakage.

[0003] In the existing technology, it is generally adopted to set a level sensor on the fully open skylight plug plate of the middle trough of the scraper conveyor to monitor the chain path of the middle trough. Since the performance and parameter settings of different level sensors are different, adaptation and improvement are required. In order to test and verify the applicability of different improved level sensors on the middle troughs of scraper conveyors of different specifications, it is necessary to frequently test on scraper conveyors of different specifications. During the test, it is necessary to frequently dismantle the fully open skylight plug plate of the middle trough of each scraper conveyor to assemble the level sensor.
