Description

Technical Field

[0001] The utility model relates to the technical field of scraper conveyors, in particular to a scraper conveyor for a fully mechanized mining working face in a coal mine. Background Art

[0002] As an important part of mining transportation machinery, scraper conveyor is widely used in coal mining, metallurgy, building materials, chemical industry, thermal power and other industries. Its main function is to transport and transfer the coal mined by the coal mining machine to the subsequent transportation equipment and provide corresponding connection means; the existing scraper conveyor for coal mining usually adopts open scraper conveyor, and the coal debris will be spread into the air, which will affect the health of the workers; although there are also scraper conveyors with shell sealing design, which can prevent coal debris from spreading into the air, but when the coal debris is put into the feed port, a large amount of smoke and dust will still be spread at the feed port, polluting the working environment and not conducive to the work of the workers.

[0003] A Chinese patent discloses a scraper conveyor for a fully mechanized coal mining face (authorization announcement number CN217806835U). In this patented technology, when coal debris is put in, the closing plate is opened under the impact of the coal debris, and the torsion spring is in a torsion state. After the coal debris is put in, the closing plate is reset under the action of the torsion spring to achieve the purpose of closing and prevent smoke and dust from spreading. The water pump is turned on to inject water into the waterway and spray it out from the water outlet to achieve the purpose of dust reduction, further reducing the spread of smoke and dust and improving the working environment.

[0004] However, it has certain disadvantages: no matter whether it is a closed plate or water hole spraying, it can only prevent smoke and dust from floating out of the shell after the coal is placed, and it is impossible to effectively prevent a large amount of smoke and dust in the coal from floating into the surrounding air to form air pollution during the placement process.
