In the figure: 1-scraper conveyor cover, 2-elbow, 3-inclined pipe, 4-tee cover, 5-belt conveyor cover, 6-tail cover, 7-slider, 8-nozzle .

Detailed ways

With reference to the accompanying drawings, an open-pit continuous mining machine conveying dust removal device includes a scraper conveyor shield 1 and a belt conveyor shield 5 . An elbow 2 is connected to the end of the scraper conveyor shield 1, and the other end of the elbow 2 is connected to an inclined pipe 3, and the inclined pipe 3 is connected to the belt conveyor shield 5 through the tee shield 4. The setting of the inclined pipe 3 can reduce the impact of the transported coal on the belt conveyor and prolong the service life of the belt. A tail cover 6 is connected at the end of the belt conveyor cover 5 .

As a further improvement to the utility model, the above-mentioned tail cover 6 is designed in the form of an elbow, and a spray device is arranged on the tail cover 6. The spray device includes 10 nozzles 8, and the nozzles 8 are evenly arranged at the outlet of the tail cover 6. place. The dust-reducing agent is ejected from the nozzle 8, which can eliminate the dust generated in the coal falling process.

Furthermore, the above-mentioned inclined pipe 3 can be set as a section with a circular cross section or two upper and lower sections. Slides within the upper section for easy installation and servicing.

Further, the outer diameter of the inclined pipe 3 and the inner diameter of the three-way shield 4 form a clearance fit. The inner diameter of the three-way shield 4 forms a clearance fit with the outer diameter of the belt conveyor shield 5 .

Furthermore, the scraper conveyor guard 1 and the belt conveyor guard 5 are arranged in a four-section structure with a semicircular cross-section, and are split in pairs. Of course, the belt conveyor shield 5 can also be designed into other different segment numbers according to the length of the belt conveyor.

The working principle of the present utility model is described below:

When the open-pit continuous miner is working normally, the coal transported by the scraper conveyor falls on the belt conveyor through the inclined pipe and the three-way shield, and the impact of the coal on the belt conveyor is reduced by the buffering effect of the inclined pipe. force. The coal is conveyed to the tail hood by the belt conveyor, so that it falls into the transportation equipment or coal yard through the tail hood. During this conveying process, the coal passes through the relatively sealed space of the scraper conveyor shield, elbow, inclined pipe, tee shield, belt conveyor shield and tail shield, thereby eliminating the diffusion of dust. Under the action of the spray device of the tail hood, the dust generated during the process of coal falling from the tail hood into the transportation equipment or coal yard is also effectively controlled.

Parts not mentioned in the above methods can be realized by adopting or referring to existing technologies.

It should be noted that under the teaching of this specification, any equivalent replacement or obvious modification made by those skilled in the art shall fall within the protection scope of the present utility model.
