A mining drill bit with shock absorbing function

Abstract

The invention discloses a drill with a damping function for mining. The drill comprises a drill body, a second fixation shaft, a mounting sleeve and a bolt; a first fixation shaft is fixedly mounted at the top of the drill body, a limiting plate is mounted on the outer surface of the first fixation shaft, the second fixation shaft is fixedly mounted at the top of the first fixation shaft, and a connecting groove is formed in the second fixation shaft; the mounting sleeve is mounted at the outer side of the drill body, a limiting groove is formed in the mounting sleeve, a first mounting grooveis formed above the limiting groove, and the bolt is connected with the connecting groove, and penetrates through the connecting groove and the mounting sleeve to be connected with the nut. Accordingto the drill with the damping function for mining, after the drill body and the mounting sleeve are fixedly mounted, the mounting sleeve drives the drill body to crush ore, the drill body telescopically runs on the mounting sleeve, and thus vibration generated when the drill body crushes the ore is reduced.

Description

technical field [0001] The invention relates to the technical field of drill bits, in particular to a mining drill bit with a shock-absorbing function. Background technique [0002] The drill bit is a tool used for crushing or drilling hard objects. It effectively enables the mining equipment to rotate the drill bit at a high speed, so that the drill bit can crush the ore. [0003] At present, the common mining drill bits on the market do not have the function of shock absorption when crushing ore, so that the service life of the mining drill bit is reduced and the number of times to replace the drill bit increases. In view of the above problems, Innovative design based on the original mining drill bit. Contents of the invention [0004] The object of the present invention is to provide a mining drill bit with a shock absorbing function to solve the problem that the common mining drill bits on the market proposed in the above-mentioned background technology do not have sh...

Problems solved by technology

[0004] The object of the present invention is to provide a mining drill bit with a shock absorbing function to solve the problem that the common mining drill bits on the market proposed in the above-mentioned background technology do not have shock absorbing functions when crushing ore. The vibration function reduces the service life of the mining drill bit and increases the number of times to replace the drill bit.
