Description

Technical Field

[0001] The utility model relates to the field of dust removal equipment, in particular to a mobile dust removal duct for mining. Background Art

[0002] Dust removal in mine tunnels generally includes the installation of fixed dust removal facilities and mobile dust removal facilities. Mobile dust removal facilities are mainly used for temporary dust removal on work surfaces. The dust removal terminal of the equipment can be moved to absorb and process the dust from the point source to maintain the air quality of the work surface. Generally, mobile dust removal equipment is equipped with a telescopic air duct, but the span is small, and the operating area of ​​the mobile dust removal equipment is limited.

[0003] For example, the patented mobile dust removal duct for mining (Announcement No.: CN209040882U) includes a telescopic duct and a telescopic crossbar. The telescopic crossbar includes a plurality of hollow thick rods and a plurality of thin rods. The two ends of the thin rods are movably installed in the hollow of the thick rods. The thick rods and the thin rods are alternately formed into a rod with a telescopic length. The telescopic duct is provided with a plurality of annular hoops in sequence along the longitudinal direction. The annular hoops are fixed on the outer wall of the telescopic duct. The top of the annular hoop is connected with an annular hook. The hook is sleeved on the telescopic crossbar and moves longitudinally along the telescopic crossbar. A bracket is also fixedly installed on the thick rod of the telescopic crossbar. The bottom of the bracket is provided with a roller. The roller is located below the telescopic duct. The mobile dust removal duct for mining provided by the utility model increases the span of the duct. The duct is supported by the telescopic crossbar and will not bend to affect the air duct. The moving range of the mobile dust removal equipment terminal can be increased, and the working area can be increased.

[0004] The above patent increases the working area by telescopic crossbars and air ducts. In daily use, the telescopic crossbar drives the air duct to expand and contract, causing the air duct to only move horizontally, and the length of the air duct is fixed. Therefore, when the depth and angle of the mine are too complicated, it is difficult to move the air duct close to the dust source to discharge the dust, which reduces the application range of the device. Therefore, it is necessary to invent a mine dust removal mobile air duct to solve the above problem. Utility Model Content
