The working principle of the buried coal mining scraper conveyor is: the material being conveyed will continuously output the material by the friction between the moving chain scraper and the conveyed material in the closed shell. This MS type buried coal mining scraper conveyor The drag chain and scraper of the slab coal mining scraper conveyor are buried in the material, the scraper only occupies a part of the cross section of the trough, and the material occupies most of the cross section of the trough. The buried coal mining scraper conveyor produced by the company also has MC type, MZ type inclined conveying and vertical conveying materials. When conveying horizontally, the scraper used is a flat strip, and the cutting force of the chain and scraper embedded in the bulk material on the bulk material layer is greater than the resistance of the groove wall to the bulk material, so that the bulk material moves forward with the scraper. At this time, the ratio of the height of the moving material layer to the width of the groove is within a certain ratio range, and the material flow is stable.
The buried coal mining scraper conveyor can not only convey horizontally, but also inclined and vertically; it can not only convey by a single machine, but also can be arranged in combination and conveyed in series; it can also multi-point feeding and multi-point unloading, and its process layout is more flexible. Because the shell is closed, the working conditions can be significantly improved when conveying materials, and environmental pollution can be prevented.
