Problems solved by technology
[0005] In order to overcome the shortcomings of the existing technology, a multi-purpose caving support with coal dust removal function is proposed, which solves the problem that when the caving support is placed inside the mine, during the mining process of the coal seam inside the coal mine, A lot of dust is often mixed in the air, and ordinary filter equipment is easily blocked by a large amount of dust

The invention discloses a multi-purpose top-coal caving support with the function of coal dust removal. By setting a dust suction mechanism at the lower end of the top beam, the fan can drive the external air into the interior of the air duct, and then filter it through the dust suction bag. And transported to the inside of the exhaust pipe to reduce the dust content in the air and dust removal, the present invention sets a dust discharge mechanism on the surface of each layer of the dust filter screen facing the air inlet pipe of the dust suction bag , the dust discharge mechanism can automatically discharge the dust filtered on the dust filter to ensure the discharge capacity of the dust and realize the automatic dust discharge function; when the present invention is vacuuming, the fan continues to work, and the dust removal fan Intermittent work, so that the dust on the dust filter is discharged intermittently, and the dust removal fan and wind mechanism are set so that the wind speed in the dust discharge pipe is at least 1.5 times greater than the wind speed in the dust suction bag. times, can effectively improve the dust removal capacity.
Description
technical field [0001] The invention relates to the technical field of hydraulic supports, in particular to a multi-purpose top-coal caving support with the function of removing coal dust. Background technique [0002] The hydraulic support is the main equipment of the comprehensive mechanized working face. It can reliably and effectively support and control the roof of the working face, isolate the goaf, maintain a safe underground working space, and realize the mechanized movement of the mining face and its related equipment. The bracket cooperates with the shearer, the flexible conveyor and the trough transfer machine to form a comprehensive mechanized equipment for the mining face, thus creating conditions for high-yield, high-efficiency and safe production in the underground mining of coal mines. For the top-coal support, the front portion of the top-coal support base is provided with a front slide, that is, a front slide, and the rear portion is provided with a rear sl...
