Abstract

The invention provides a dust removal device with a wind-water mixing function and a drilling rig thereof. The dust removal device comprises a compressed air system, a wind-water mixing box, a first pipeline, a water containing pipe, a second pipeline, a third pipeline, and a drilling air inlet one-way valve, wherein an inlet of the first pipeline is connected with the compressed air system, an outlet of the first pipeline communicates with the top of the wind-water mixing box, the water containing pipe communicates with the wind-water mixing box, and supplies water to the wind-water mixing box, the second pipeline is arranged at the bottom of the wind-water mixing box and communicates with a drill rod of the drilling rig, the third pipeline is connected between the first pipeline and thesecond pipeline, the drilling air inlet one-way valve is arranged on the third pipeline, and an inlet of the drilling air inlet one-way valve faces the first pipeline. High-pressure blast and water are synchronously fed into a drilling impactor, the high-pressure blast provides power for impacting coring drilling, rock powder and rock debris generated in the drilling process are wetted by the water, the drilling effect of an impacting drilling coring sample is guaranteed, and the flying situation of the rock powder is reduced; and the dust removal device has very high practical value and promotional value in the field of tunnel geological advance impacting coring drilling.

Description

technical field [0001] The invention relates to the technical field of advanced percussion core drilling in tunnel geology, in particular to a wind-water mixing dust removal device and a drilling rig. Background technique [0002] The railway tunnel project occupies a very important proportion in the railway construction. It is a control project in the railway construction project. The safe construction of the railway tunnel project not only directly affects the smooth progress of the entire project, but also directly relates to the investment and progress of the entire railway project. , in order to ensure the construction safety of railway tunnel projects, for high-risk tunnels, the advanced geological prediction of tunnels is included in the construction process management of railway tunnels. At present, some projects in railway construction require all tunnels to carry out advanced geological prediction of tunnels. [0003] In the advanced geological prediction of railwa...
