Automatic sweeper for blasting holes

Abstract

The invention discloses an automatic sweeper for blasting holes. The automatic sweeper for the blasting holes comprises a sleeving pipe, a direct current motor is arranged at one end of the sleeving pipe, and a connecting sleeve is arranged at the end of an output shaft of the direct current motor. An assembly hole is formed in the connecting sleeve in the axial direction of the output shaft of the direct current motor, a key groove is formed in the assembly hole, and a detachable sweeping head is assembled on the connecting sleeve. Batteries are arranged on the position, adjacent to the direct current motor, in the sleeving pipe, one ends of the batteries are connected with the direct current motor through wires, and the other ends of the batteries are provided with a control switch. A press button of the control switch extends out of the sleeving pipe. According to the automatic sweeper for the blasting holes, in the whole sweeping process, large equipment and lots of professional workers are not needed, sweeping can be rapidly completed through operation of one person, the sweeping operation time of the blast holes in blasting construction is greatly shortened, the good-quality blast-hole environment is provided for explosive loading construction, and the accuracy of explosive loading is improved.

Description

technical field [0001] The invention relates to a sweeper for blasting blastholes, in particular to an automatic sweeper for blasting blastholes. Background technique [0002] In the demolition blasting, the debris remaining in the blast hole directly affects the charge and filling quality of the blast hole. An excellent blast hole environment is a favorable guarantee for achieving good blasting effects and reducing blasting flying rocks. Due to the different structures and materials of the structures, the amount and size of the construction debris remaining in the blastholes after the drilling is not the same. The hole is easily deformed by external force; the structural stability of reinforced concrete structures is good, and powdery debris remains in the blasthole after drilling; in rainy weather, there will be a lot of water in the exposed blasthole. Failure to handle explosives will affect explosive performance. [0003] In actual construction, the cleaning methods of...

AI Technical Summary

Problems solved by technology

[0004] On-site construction workers often use wire hooks to extend into the hole and take out the residue in a circular manner. Due to the simple equipment, the cleaning of the blast hole cannot achieve the expected effect, and the stuck hole and deformation cannot be dealt with in time. There are too many residues at the bottom so that the charge personnel cannot roll the charge. Sending to the bottom, resulting in insufficient final charge, insufficient filling length, stuck hole, broken charge, etc., resulting in adverse effects such as the inability of the priming charge to detonate the explosive.

[0005] Generally, air compressor equipment is used to connect hand-held rock drills for drilling in demolition blasting. During construction, air compressors are often used to connect high-pressure pipes to output high-pressure air to blow out debris in the holes. Blowing out dust will pollute the construction environment; when encountering stuck holes, deformation, etc. When the blast hole is repaired, the drilling rig will be used, which will increase the construction time and construction cost

[0006] When encountering rainy weather, there is a lot of water in the blast hole, and the construction workers will use sticks and iron wires to tie the top of the sponge to suck out the water in the hole. The operation is troublesome and time-consuming. Sometimes the top sponge will fall off in the hole, affecting the charge quality
