Description

Technical Field

[0001] The utility model relates to a maintenance device, in particular to a drill bit maintenance device based on coal mining, which can be used for cleaning the coal mining drill bit and is convenient for subsequent rust prevention and other processes. Background Art

[0002] During coal mining, drilling or excavation operations are often required. Therefore, the drill bit is one of the most common accessories in coal mining. In order to reduce equipment wear and tear and increase the service life of the drill bit, the drill bit needs to be maintained by special drill bit maintenance equipment after use. There are many types of equipment for drill bit maintenance on the market. For example: Chinese patent CN214273526U discloses a drill bit maintenance device for coal mining, which can dry and rust-proof the drill bit. Before placing it in the equipment, the drill bit needs to be cleaned to remove debris from the drill bit gap; Chinese patent CN219985461U discloses a drill bit maintenance device for coal mining, which mainly discloses a brush structure, which uses the brush to brush away debris from the drill bit gap. The device of Chinese patent CN214273526U cannot clean the debris in the drill bit. Although the brush disclosed in Chinese patent CN219985461U can clean it, it can only be cleaned one by one by holding the brush, which is not efficient. Moreover, some drill bits are heavy and need to be turned over during the cleaning process, which also requires a lot of manual labor.
