Embodiment Construction

[0023] 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.

[0024] 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,...

Abstract

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, comprising a dust extraction port and a cover, and the dust extraction port is arranged on a cutting arm near a pivot shaft The upper edge of the dust extraction port is pivotally provided with a cover. The cover includes a plate body and shields arranged on both sides of the plate body. Dust outlet, the upper surface of the end of the dust extraction pipe close to the dust extraction port is an inclined plane, the plate body is lapped on the inclined surface, and the shield covers the opening between the dust extraction port and the dust extraction pipe, so that the dust extraction pipe and the exhaust pipe A movable seal is formed between the dust ports. The structure of this application is a purely mechanical seal. Compared with parts such as bellows, it has better durability, more reliability, longer life and is not easy to be damaged.

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...
