It is suitable for conveying powder, granular, small block low-abrasive materials and bagged materials that are easy to take out, such as coal, gravel, sand, cement, fertilizer, grain, etc. As the most ideal high-efficiency continuous transportation equipment for coal mines, belt conveyor has the advantages of long transportation distance, large transportation volume, continuous transportation, etc., and reliable operation, easy to realize automation and centralized control. Especially for high-yield and high-efficiency mines, belt conveyor has become the key equipment of coal mining mechatronics technology and equipment.

[0003] For example, a Chinese patent with publication number CN216188435U discloses a semi-fixed retractable belt conveyor for coal mines, comprising a base, wherein two ends of the top of the base are respectively fixedly connected with a slide rail and a fixed frame, an end of the top of the slide rail close to the fixed frame is fixedly connected with a hydraulic rod, and the telescopic end of the hydraulic rod is fixedly connected with a slide seat, and a motor is fixedly connected to one side of the outer wall of the fixed frame, and the motor drive shaft passes through the fixed frame and is fixedly connected with a driving wheel, and the top of the slide seat is rotatably connected with a driven wheel, and the outer side walls of the driving wheel and the driven wheel are jointly provided with a conveyor belt; a groove is provided in the middle of the base, and a first electric telescopic rod is fixedly connected to the bottom of the groove, and the top of the telescopic end of the first electric telescopic rod is rotatably connected with a first limiting wheel, a second electric telescopic rod is provided between the groove and the slide rail, and the top of the telescopic end of the second electric telescopic rod is rotatably connected with a second limiting wheel, a bracket is provided between the groove and the fixed frame, and a bracket is provided on the top of the bracket, a card slot is provided at one end of the bracket close to the slide rail, and an extension bracket is provided at one end of the bracket away from the fixed frame, and a supporting wheel is provided on the extension bracket and the top of the bracket;
