[0034] When in use, dust will be raised during the operation of the down-the-hole drilling vehicle. The dust suction air pump 4 can suck the dust into the dust removal box 1. The second filter 102 and the third filter 103 can filter the dust gas layer by layer to separate the dust particles in the dust gas. When the dust gas passes through the first filter 101, larger particles will be intercepted. When passing through the second filter 102, smaller particles will be further intercepted. When passing through the third filter 103, even smaller particles will also be intercepted.

[0035] When cleaning the filter, the motor 201 drives the brush rod 302 to rotate through the rotating shaft 2. The rotating brush rod 302 can help clean the dust accumulated on the filter. The accumulated dust will fall into the collection box 5 through the discharge port 501. The collection box 5 collects the cleaned dust particles. When disassembling the brush rod 302, the first bolt 303 is displaced by screwing it. When one end of the first bolt 303 is disengaged from the socket on the plug block 301, the restriction on the plug block 301 can be released, and then the brush rod 302 can be disassembled.

[0036] To summarize, the dust removal box of the down-the-hole drilling vehicle is provided with a motor 201, a rotating shaft 2 and a brush rod 302. The motor 201 drives the brush rod 302 to rotate through the rotating shaft 2. The rotating brush rod 302 can help clean the dust accumulated on the filter net, clean up the accumulated dust, keep the filter net clean, and further maintain a good filtering effect of the filter net. By providing a first bolt 303, the first bolt 303 is displaced by screwing the first bolt 303. When one end of the first bolt 303 is disengaged from the socket on the plug block 301, the restriction on the plug block 301 can be released, and then the brush rod 302 can be disassembled, thereby facilitating the maintenance and cleaning of the brush rod 302.
