Abstract

The invention relates to the field of mining equipment, in particular to a drainable drill sleeve. The drainable drill sleeve is provided with an upper limiting hole and a hollow drainage tube; drill connection fixing degree is improved; an external drainage tube is omitted; and by a drill with a drainage groove, the overall working efficiency is improved. Limiting holes are respectively formed in the sleeve and the drill, so that the sleeve is connected with the drill firmly; the multistage sleeve is hollow, after the drill sleeve is connected with the drill, a drainage tube is formed, and another drainage tube for drilling fluid is omitted; and the mining efficiency is improved.

Description

technical field [0001] The invention relates to the field of mining equipment, in particular to a drainable drill bit sleeve. Background technique [0002] In mining equipment, the drill bit is a very important component. The drill bit is directly or indirectly fixed on the shaft of the mining device with a sleeve. The cooperation between the sleeve and the drill bit determines the mining efficiency to a certain extent. [0003] The technical characteristics of the sleeve: 1. It is suitable for the construction of steel bar connection in the cold extrusion connection technology structure of reinforced concrete steel bar sleeve of various structures that bear the two-way force of tension and compression. 2. Material saving and energy saving are not limited by the composition and type of steel bars. 3. It can be connected in all directions. 4. It can be prefabricated in advance, factory-like operation, without taking up the construction period, and can be constructed around ...
