Abstract

The invention belongs to the technical field of tunnel roadway cantilever heading machine dust collector, concretely relates to a high efficient dedusting system with an air channel arranged in the central part of a heading machine, and solves the problems of poor integrated level, large occupation space, inflexible operations existed in a present cantilever heading machine airborne dedusting system. the high efficient dedusting system comprises an air inlet, an air channel, a deduster and a blower fan, one end of the air channel is connected with the air inlet, the other end of the air channel is connected with the deduster, the deduster and the blower fan are arranged at the end part of the heading machine, and is characterized in that the air inlet is arranged at the front end of the frame which is positioned between a cutting part and a loading part of the heading machine, the air channel is placed in the central part of the frame and integrated with the frame. The present invention has the advantages that the dedusting efficiency can reach more than 90%, and is capable of greatly improving the work environment of the present driving working face, effectively controlling the coal dust blast, substantially promoting the safety production work of coal mine and reducing the incidence rate of pneumoconiosis in coal mine further.

Description

technical field [0001] The invention belongs to the technical field of roadway cantilever type roadheader dust removal devices, and in particular relates to an efficient dust removal system with an air duct arranged in the middle of the roadheader. Background technique [0002] The existing cantilever-type roadheader matching dust removal device is usually located behind the loader behind the roadheader and moves together with the loader. When tunneling up and down the mountain, it is easy to bend or even damage the loader. If it is uneven, it is easy to fall off the road or even roll over, which greatly increases the safety hazard; at the same time, the suction duct in front of the dust collector is easily damaged, which leads to a decrease in the air suction volume of the dust collector, which in turn affects the dust removal efficiency. [0003] However, the existing airborne dust removal device of the cantilever type roadheader has poor integration with the cantilever ty...
