Strip mine ordered impact excavating device and working method thereof

Abstract

The invention belongs to the technical field of ore mining, particularly relates to a strip mine ordered impact excavation device and a working method thereof. The device and the method aim to solve the problems that in the impact excavation process of ores, the size of a drill bit cannot be changed so that impact excavation cannot be performed on the ores with different sizes, and the ore mining efficiency is greatly reduced. According to the scheme, the device comprises a base and a motor and is characterized in that an output shaft of the motor is connected to a fixing box through a coupler, a driving motor is arranged on the outer wall of the top of the fixing box, an output shaft of the driving motor is connected to a lead screw through a bevel gear, and the outer wall of the lead screw is sleeved with sliding rings distributed at equal intervals; connecting rods which are annularly distributed at equal intervals are hinged to the outer walls of the sliding rings; and pushing blocks are hinged to the ends, away from the sliding rings, of the connecting rods. According to the device and the method, the drill bits with different diameters can be adjusted for use according to the size of ores, the application range of the device is widened, and the mining efficiency of the ores is improved.

Description

technical field [0001] The invention relates to the technical field of ore mining, in particular to an orderly impact excavation device for an open-pit mine and a working method thereof. Background technique [0002] Sky mine is to strip off the floating soil and surrounding rock covering the upper part of the ore body and its surroundings, transport the waste rock to the dump site, and directly mine ore from the open ore body. When the ore body is buried shallow or there is an outcrop When using open-pit mining, it is superior to underground mining. The work of stripping the upper rock and soil is called stripping, and the ratio of the amount of stripped rock and soil to the amount of ore mined is called the stripping ratio. If the stripping ratio is too large, the cost of open-pit mining High, the method of underground mining should be used instead. In the process of open-pit mining, it is often necessary to use impact excavation devices to split the hard ore. [0003] In...

AI Technical Summary

Problems solved by technology

[0005] Based on the technical problem that the size of the drill bit cannot be changed during the impact excavation process of the ore, it is impossible to perform impact excavation for ores of different sizes, which greatly reduces the mining efficiency of the ore. The present invention proposes an orderly impact excavation for open pit mines. Device and its working method
