Description

Technical Field

[0001] The utility model relates to the field of coal mining, and particularly relates to a coal conveying device for coal mining in coal mines. Background Technique

[0002] During the coal mining process, in order to classify and transport the mined coal subsequently, it is necessary to crush the larger pieces of coal so that the coal forms a smaller volume, which facilitates subsequent transportation and use; after the coal is crushed, it is usually necessary to move the crushed coal to a suitable storage area. Therefore, most of the time, a conveying device is used to move the coal. However, when the existing coal conveying device conveys coal, coal ash will remain on the conveyor belt. As the coal ash accumulates, it is easy to cause moving pollution to the conveyor belt. At the same time, long-term accumulation is also easy to erode the conveyor belt, which will easily affect the safety of the conveyor belt during use, and to a certain extent, it will also shorten the service life of the conveyor belt and increase the conveying cost.

[0003] After retrieval, a conveying device and a coal mining crushing device with the authorization announcement number of CN220885866U. Although this device can clean the conveyor belt by using a cleaning brush to avoid the pollution caused by coal ash adhering to the conveyor belt, because coal ash is easy to adhere to the surface of the conveyor belt when it is wet, it is difficult for this device to completely clean the conveyor belt only through the cleaning brush, and it is easy to cause coal ash to remain on the surface of the conveyor belt.

[0004] Therefore, a coal conveying device for coal mining in coal mines is proposed to solve the above problems. Content of the Utility Model
