Description

Technical Field

[0001] The utility model relates to the technical field of tunneling machines, in particular to a dust removal device for a tunneling machine. Background Art

[0002] The comprehensive mechanized roadheader is short for comprehensive mechanized roadheader. It is a comprehensive mechanized equipment that integrates multiple functions such as roadheading, rock loading, coal transportation, and even support and road nailing. The working mode of the roadheader is mainly composed of a traveling mechanism, a working mechanism, a loading mechanism, and a transfer mechanism. The traveling mechanism moves forward, and the cutting head in the working mechanism continuously breaks the rock and transports the broken rock away. The roadheader has the advantages of safety, high efficiency, and good tunnel quality.

[0003] When the existing multi-purpose excavator is in use, a large amount of dust will be generated at the drill bit. Since the existing multi-purpose excavator adopts wind dust suction, but this method has poor adsorption effect, when a large amount of dust appears, it will block the sight of the construction workers, and the dust will affect their health. Therefore, we propose a dust removal device for a multi-purpose excavator to solve the above problems. Utility Model Content

By sleeved on the surface of the connecting port 42 with the mounting head 43, the delivery water pipe 44 can inject external water into the water spray pipe 3 through the diversion water pipe 41, so as to facilitate the sedimentation of dust.

[0030] Further, see Figure 3 and Figure 4 It can be known that the shielding mechanism 5 includes a guide groove 51, and the upper and lower sides of the water spray pipe 3 are fixedly connected with the guide groove 51, and a limit slider 52 is inserted inside the guide groove 51, and the limit slider 52 is fixedly connected to the inner wall of the protective outer frame 53. By matching the inner wall size of the guide groove 51 with the surface size of the limit slider 52, the movement of the limit protective outer frame 53 can be guided.
