[0002] As the main channel for materials to be transported autonomously under the action of gravity in coal preparation plants, the four-way batching chute is responsible for connecting and transporting materials between the washing equipment and coal preparation equipment such as storage and transportation devices. It can transfer materials from one device to another to ensure that the coal can flow smoothly during the coal preparation process.

[0003] When using a chute to transport wet coal for a long time, coal will usually adhere to the inside of the chute. The conventional way to clean the sticky coal is to use tools or manual water flushing. However, no matter which cleaning method is used, the machine needs to be shut down during the cleaning process, which affects production efficiency. In addition, the weather in the north is cold in winter. When the coal is humid, the coal remaining in the chute is easy to freeze to the inner wall of the chute after the machine is shut down at night, which increases the difficulty of cleaning the chute.
