Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyor cleaning devices, in particular to a coal sweeping device for a tail drum. Background Art

[0002] The cleaning of the tail drum of a belt conveyor refers to the process of cleaning and maintaining the driving drum or turning drum at the tail of the belt conveyor. The tail drum is usually located at the end of the belt conveyor and is responsible for driving or adjusting the direction of the belt. The main purpose of cleaning the tail drum is to ensure the smooth and safe operation of the belt conveyor and avoid failures or damages caused by dirt, dust or other debris at the tail drum part.

[0003] A plow-type cleaner is used one meter away from the back of the tail belt of the coal conveying belt conveyor to clean the remaining coal on the coal conveying belt conveyor.

[0004] After retrieval, the application number 201220120011.X discloses a cleaning device for a belt conveyor, especially a drum cleaning device for a belt conveyor. The left lower end of a trough-shaped coal scraping knife is hinged to the frame near the tail drum of the belt conveyor, and the right lower end of the coal scraping knife is hinged to a bolt, and the bolt is fixed to the frame through a nut. The gap between the coal scraping knife and the drum can be adjusted through the bolt and the nut. The above technical solution has a simple structure, is convenient to adjust, automatically cleans the remaining coal at the tail, and reduces equipment accidents and personal injuries.

[0005] In actual use, the cleaning force of the cleaner is limited, and a single cleaning method is difficult to comprehensively and efficiently remove the remaining coal on the coal conveying belt. The defects of a single cleaning method include:

[0006] 1. Limitation: A single cleaning mechanism may not be able to completely cover all parts of the tail drum, especially around the tail drum or in inaccessible corners;

[0007] 2. Unstable cleaning effect: A single cleaning mechanism may not be able to ensure the same cleaning effect every time, especially when facing the remaining coal attached to the belt conveyor, it is difficult to achieve an ideal cleaning effect.

[0008] Therefore, we propose a coal sweeping device for a tail drum. Utility Model Content
