[0002] Currently, coal mines are areas where humans extract coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. During the mining process, coal needs to be transported using transportation equipment so that people can use it.

[0003] Chinese utility model patent CN211252619U discloses a coal mining transportation device with cleaning and drying functions, including a transport frame, a drive motor, heating wires, and a water pump. A processing box is fixedly installed on top of the transport frame, and the drive motor is installed on top of the processing box. The output end of the drive motor is connected to a first connecting rod. A second connecting rod is connected inside the first connecting rod, and the bottom of the second connecting rod is connected to a mesh screen. A heat-conducting plate is provided inside the processing box, and a heating frame is provided on the outer end face of the processing box. A water pump is fixedly installed on the left side of the processing box, and one end of the water pump is connected to the top of the processing box through a water pipe. The above patent, with its heating frame and heat-conducting plate, can heat the inside of the processing box through the heating wires inside the heating frame, thereby facilitating the drying of the cleaned coal and improving the coal processing effect.

[0004] However, the above-mentioned patents have the following shortcomings: 1. The above-mentioned patent uses a drive motor to drive the stirring blades to rotate, so as to facilitate the cleaning of coal mines. This method of cleaning coal mines often breaks the coal mines due to the rotation of the stirring blades. Although the broken coal mines can stay on the mesh, they are not convenient for workers to collect. Utility Model Content
