An automatic cleaning device for scraping coal slag impurities at the tail of a coal mine belt conveyor

Abstract

The invention discloses an automatic cleaning device for tail scraped coal slag impurities of a coal mine belt conveyor. The automatic cleaning device comprises a supporting frame, a roller and a conveyor belt, wherein the roller is externally connected with the output end of a servo motor; the conveyor belt sleeves the roller; and the middle part of the roller is rotatably connected with the upper end of the supporting frame. The automatic cleaning device for the tail scraped coal slag impurities of the coal mine belt conveyor is simple in structure; when coal slag or difficult-to-clear impurities on the conveyor belt are adhered on the conveyor belt, a scraping knife scrapes off the coal slag or difficult-to-clear impurities from the moving conveyor belt; if things are difficult to clear, the scraping knife is connected with a circuit through force transmission property, so that a water pump is powered, and therefore, the impurities or the coal slag is impacted by water while immersed into water, and is completely cleared through the action of the scraping knife. Meanwhile, a floating plate and a floating ball are utilized to automatically control water injection of a cleaning solution tank; and the whole device does not need manual control, and can achieve the effect of automatically and efficiently clearing.

Description

technical field [0001] The invention relates to the technical field related to coal mine machinery, in particular to an automatic cleaning device for scraping coal slag impurities at the tail of a coal mine belt conveyor. Background technique [0002] Coal is an important energy source for human beings. After underground coal is extracted, it is mainly transported through a retractable belt conveyor. During the operation of the belt conveyor, it is inevitable that the belt will be scattered due to other reasons such as belt deviation. Coal or impurities are sprinkled on the bottom belt, and as the belt moves to the tail, in order to prevent coal from entering the tail of the belt conveyor and causing damage to the belt, which will affect safety production and coal output, it is necessary to install it at the tail of the machine. Coal scraping device, yet the currently used coal scraping device has the defect that coal scraping is not clean, which affects the transportation o...

[0002] Coal is an important energy source for human beings. After underground coal is extracted, it is mainly transported through a retractable belt conveyor. During the operation of the belt conveyor, it is inevitable that the belt will be scattered due to other reasons such as belt deviation. Coal or impurities are sprinkled on the bottom belt, and as the belt moves to the tail, in order to prevent coal from entering the tail of the belt conveyor and causing damage to the belt, which will affect safety production and coal output, it is necessary to install it at the tail of the machine. Coal scraping device, however, the currently used coal scraping device has the defect that the coal is not scraped cleanly, which affects the transportation of coal, and some impurities are stuck on the belt, which is difficult to scrape off
