Description

Technical Field

[0001] The utility model relates to the technical field of drill bits for grinding water channels, in particular to a water channel grinding device for a mining drill bit. Background Art

[0002] The background technology of the water channel grinding device for mining drill bits is mainly related to the maintenance needs of the water channels of drill bits in the mining industry and the problems existing in traditional grinding methods. The main function of the water channel is to guide the coolant or flushing liquid to flow through the drill bit to cool the drill bit and remove the debris generated during the drilling process. Due to the frequent use of the drill bit and the harsh working environment, the edge of the water channel is easily worn or deformed, resulting in poor circulation of the coolant, affecting the heat dissipation and cleaning effect of the drill bit. Regular grinding and repair of the water channel is an important step in maintaining the performance of the drill bit.

[0003] Chinese patent CN213104682U discloses a secondary grinding alloy drill bit, including a drill rod and a drill bit. A protrusion is arranged on the top of the drill bit, and the number of the protrusions is six. The six protrusions are annularly installed on the top of the drill rod. A groove one is opened at the bottom of the drill rod, and the number of the grooves one is six. The shapes and sizes of the six grooves one are respectively adapted to the shapes and sizes of the six protrusions. The six protrusions respectively penetrate the six grooves one and extend into the six grooves one. Two ferrules are arranged on the outer surface of the connection between the drill rod and the drill bit. The utility model can separate the drill bit from the drill rod by opening the throat clamp and removing the two ferrules. Then, a new drill bit is clamped with the drill rod through the protrusion, and then the ferrule is closed and the two ferrules are fixed with the throat clamp, so as to complete the replacement of the drill bit, make it convenient and quick to replace, avoid the need to directly replace the drill rod and the drill bit, and thus save a lot of resources.
