Description

Technical Field

[0001] The present application relates to the technical field of mining equipment, and in particular to a slag stopper for a rotary drill. Background Art

[0002] A rotary drill slag stopper is a crucial device in the field of mining equipment, specifically designed to prevent and remove rock debris during drilling operations. Its design aims to improve drilling efficiency, reduce equipment wear, protect the operating environment, and ensure operator safety.

[0003] When the slag stopper is in use, it is used to block and remove rock slag during drilling operations, facilitate drilling by drilling equipment, reduce equipment wear, block rock slag, and reduce the impact on surrounding workers.

[0004] The slag stopper is used to block and remove rock debris during drilling operations. The drill bit will continuously break up the rock, generating a large amount of rock debris. If this rock debris is not removed in time, it will affect the drilling efficiency. However, the existing slag stopper is relatively fixed during use, making it difficult to adjust the position of the slag stopper according to the generation and distribution of rock debris. It is not flexible and is not convenient for workers to maintain and clean the slag stopper. This can easily affect the efficiency of the drilling operation and the safety of the workers, shortening the service life of the equipment. Utility Model Content
