Problems solved by technology

However, the orifice dust suction system is equipped with dust filters and ventilation systems, which is large in size and high in cost, and requires regular and regular maintenance. Replacement parts after damage are difficult and expensive; and the orifice vacuum The system can generally only be used for larger crawler down-the-hole drilling rigs, but cannot be used for small down-the-hole drilling rigs with only outriggers without a chassis

Abstract

The invention discloses a down-the-hole drill orifice dust removing device. The down-the-hole drill orifice dust removing device comprises a dustproof cover with a drilling rod hole for sleeving a drilling rod, multiple nozzles formed in the dustproof cover, a water connecting pipe connected above the dustproof cover and communicating with the nozzles, and a guide pipe connected under the dustproof cover and communicating with the drilling rod hole; a fixed piece is arranged at the upper part of the dustproof cover; and the dustproof cover uses a plastic material. The down-the-hole drill orifice dust removing device is small in size, low in cost, easy to obtain fittings, free of maintenance and particularly suitable for the dust removing demands during working of a small down-the-hole drill.

Description

technical field [0001] The invention relates to the field of down-the-hole drilling machines in mining machinery, in particular to a dust removal device for down-the-hole drilling. Background technique [0002] Down-the-hole rock drilling is to make the impactor dive into the hole during the rock drilling process to reduce the energy loss caused by the impact energy transmitted by the drill pipe, thereby reducing the impact of hole depth on rock drilling efficiency. The submersible drilling machine is one of the mainstream rock drilling equipment. During the rock drilling process, the submersible drilling machine will produce a large amount of gravel and dust and other wastes that damage and pollute the environment. The gravel can be collected and processed after a period of excavation time, but the dust must be followed up in time when it is generated. Otherwise, it will directly diffuse into the surrounding air and cause pollution. [0003] In the existing orifice suctio...
