Quickly mounted and dismounted cable trough of scraper conveyer

A quickly mounted and dismounted cable trough of a scraper conveyer comprises an upper trough body and a lower trough body, wherein the upper trough body and the lower trough body are separated by a horizontal partition plate, a vertical coal blocking plate fixedly connected with a middle trough of the scraper conveyer is arranged on one side of the horizontal partition plate, the upper trough body comprises two vertical baffles matched with the vertical coal blocking plate for cable installation, a guide pipe is arranged at the tops of the two vertical baffles respectively, a middle guide pipe is installed between the front guide pipe and the rear guide pipe through a locking mechanism, a U-shaped trough opening for overhauling is formed in the middle of the vertical coal blocking plate of the upper trough body, and a plug-in connecting vertical plate plugged and mounted from top to bottom is arranged in the U-shaped trough opening. The quickly mounted and dismounted cable trough enables overhauling of a coal mining machine to be performed on the premise that the whole cable trough is not dismounted, the coal mining machine can be quickly maintained, maintenance efficiency is improved, maintenance difficulty is reduced, the coal mining machine can be more convenient to maintain, convenience is brought to an underground sever operating environment, and the labor intensity of workers is reduced.
