Description

Technical Field

[0001] The utility model relates to the technical field of blasthole cleaning, in particular to a blasthole cleaner for mining engineering blasting which is easy to use. Background Art

[0002] Blasting is often required in mining engineering operations. Before blasting, the mine needs to be drilled. After the drilling operation is completed, there will usually be debris remaining deep in the hole. If the blasthole is not cleaned in time, it will easily affect the subsequent loading of explosives.

[0003] After searching, the authorization announcement number is CN218566328U, which discloses an easy-to-use blasthole cleaner for mining engineering blasting, including a main rod, which includes multiple threaded connecting rods, and a thread is provided on the outer surface of the connecting rod at the lower end. The external thread sleeve is provided with a fixed tube, and the fixed tube is fixedly connected to the scraper. A reinforcement component for strengthening the connection tightness between the connecting rod and the fixed tube is provided on the connecting rod at the lower end. The reinforcement component includes a mounting plate fixed to the outer surface of the lower end of the connecting rod.

[0004] In the process of realizing the present utility model, the inventors found that there are at least the following problems in the prior art that have not been solved. In the above case, the connecting rod is rotated to place the semi-arc-shaped side of the scraper at the bottom of the blasthole, and then the connecting rod is pulled outward. The pull rod drives the scraper to move outward. When the scraper moves, it pushes the dust and gravel toward the blasthole and finally pushes them out of the blasthole. However, during use, the blasthole may be vertical, which makes it impossible for the scraper to effectively push some fine stone chips and drill chips out of the blasthole. Moreover, the inner wall of the blasthole is usually rough, and some fine stone chips and drill chips will adhere to the inner wall of the blasthole, and the scraper cannot be effectively cleaned.

[0005] Therefore we propose a mine engineering blasting blasthole cleaner that is easy to use and can solve the above problems. Utility Model Content

[0010] As an optional solution of the technical solution of the present application, a handle is fixedly installed on one side of the shell where the connecting tube is installed, and an anti-slip sleeve is provided on the outer side of the handle.

[0011] As an optional solution of the technical solution of the present application, the air jet holes are placed on the outside of the shell, and the air jet holes are evenly distributed on the outside of the air jet straight pipe.

[0012] As an optional solution of the technical solution of the present application, the cleaning brush is placed on the outside of the shell, and the second gear is placed on the inside of the shell.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: air can be inflated into the jet straight pipe through the connecting pipe and the rotating joint, and small stones, drill cuttings and other impurities in the blasthole can be cleaned through the jet hole.
