A kind of anti-diffusion tunnel surrounding rock blasting blasthole slag cleaning device

Abstract

The invention discloses an anti-diffusion tunnel surrounding rock blasting hole slag removal device, and relates to the technical field of tunnel construction. The anti-diffusion tunnel surrounding rock blasting hole slag removal device comprises a box body; first ball bearings are fixedly connected into the left side and the right side of the box body; a first rotary shaft is fixedly connected tothe inner walls of the first ball bearings, and the right side of the surface of the first rotary shaft is fixedly connected with fan blades; and a first conical fluted disc is fixedly connected to the position, located on the left sides of the fan blades, of the surface of the first rotary shaft. According to the anti-diffusion tunnel surrounding rock blasting hole slag removal device, negativepressure forms in the box body through rotation of the fan blades, waste slag removed from blasting holes is collected into the box body through a first pipeline and prevented from being diffused intothe other blasting holes, and accordingly, the problems that a slag removal device on the market at present cannot collect waste slag removed from blasting holes, the waste slag removed from the blasting holes are prone to being diffused into the cleaned blasting holes, and then, the blasting holes are not thoroughly cleaned are effectively solved.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to an anti-diffusion device for removing slag from blast holes in tunnel surrounding rock blasting. Background technique [0002] At present, in the blasting construction process of the tunnel, blasthole laying is the primary process, and its work quality directly affects the blasting, mining and transportation of surrounding rock. Due to the influence of geological conditions and the diversity of ore rocks, the drilled holes are sometimes blocked by the rock powder falling around the hole or hole wall. Cause blocked hole or waste hole, cause blasthole to be unable to use normally, need to re-drill, therefore need to clean up the waste residue of blasthole. [0003] However, the existing slag removal device cannot collect the cleaned waste slag, and the cleaned waste slag is easily diffused into the cleaned blast hole, resulting in incomplete cleaning of the blast hole....

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an anti-diffusion slag removal device for tunnel surrounding rock blasting blast holes, which solves the problem that the slag removal devices currently on the market cannot collect the cleaned waste slag, and the cleaned waste slag is easy to collect. Diffusion into the cleaned blast hole, resulting in incomplete cleaning of the blast hole
