Embodiment Construction
[0024] The present invention will be further described in detail below in conjunction with test examples and specific embodiments. However, it should not be understood that the scope of the above subject matter of the present invention is limited to the following embodiments, and all technologies realized based on the content of the present invention belong to the scope of the present invention.
[0025] see Figure 2 ~ Figure 6 , a high-efficiency dust extraction device suitable for low-level dust sources of continuous mining machines. The continuous mining machine includes a body 200, a cutting arm 100 and a high-efficiency dust extraction device of the present application. The cutting arm 100 is pivotally arranged on the body 200 to cut The free end of the arm 100 is provided with a cutting drum 110. The high-efficiency dust extraction device applicable to the low-level dust source of the continuous mining machine of the present application includes a dust suction port 120,...

The invention relates to the technical field of coal mining machinery, in particular to an efficient dust extraction device suitable for a continuous mining machine low-level dust source. The device comprises a dust extraction opening and a cover cap, wherein the dust extraction opening is formed in the part, close to a pivot shaft, of a cutting arm, the cover cap is pivotally arranged on the upper edge of the dust extraction opening and comprises a plate body and shielding plates arranged on two side edges of the plate body correspondingly, a dust extraction pipe is arranged above a coal conveying groove, a pipe opening of the dust extraction pipe is aligned with the dust extraction opening, the upper surface of the end, close to the dust extraction opening, of the dust extraction pipe isan inclined face, the plate body is connected to the inclined face in an overlapped mode, and the shielding plates cover an opening between the dust extraction opening and the dust extraction pipe, so that movable sealing is formed between the dust extraction pipe and the dust extraction opening. The structure of the device adopts pure mechanical sealing, and compared with corrugated pipes and other parts, the device is better in durability, more reliable, longer in service life and not prone to damaging.
Description
technical field [0001] The invention relates to the technical field of coal mining machinery, in particular to a high-efficiency dust extraction device suitable for low-level dust sources of continuous miners. Background technique [0002] The continuous miner is a kind of comprehensive excavation and short-wall high-efficiency mining equipment, but the high-efficiency production brings serious dust pollution problems at the same time. Especially when the top coal is cut, the dust generated by the drum cutting seriously pollutes the workers' working environment, causing the workers to have the risk of suffering from pneumoconiosis. [0003] At present, continuous miners are equipped with dust collection equipment to collect and process the dust generated by cutting, such as figure 1 As shown, there is a cutting drum on the cutting arm of the continuous miner, and the cutting drum cuts the coal and rock mass. After the coal and rock blocks fall, they are transported out by t...
