In order to ensure the safety of personnel and production needs, a regulating wall is built in the mine and a regulating window is opened in the belt conveyor cover. According to the needs of mine transportation and ventilation, part of the transport belt has to pass through the regulating wall. When the wind flow passes through the belt hole of the regulating wall, the wind speed through the belt hole will become bigger because the ventilation section suddenly becomes smaller. During the experiment, the utility modeler found that if the hard wind shield was used, the coal on the belt conveyor would easily collide with the wind shield, and if the flexible wind shield was used, the wind speed at the belt hole was very high, and the high speed wind flow would easily blow up the flexible wind shield, so the wind shield effect was very poor and the purpose of dust control could not be achieved.

The conveyor cover for coal mine belt conveyor , belongs to the field of coal mine belt conveyor windproof equipment. In the conveying belt on both sides of the regulating wall . There is a horizontal upper baffle fixed on the top, and side baffles fixed on both sides of the conveyor belt , and there is a baffle fixed at the front opening of the upper baffle and the side baffle , and there are also a number of dust trapping baffles fixed at intervals on the rear side of the baffle, and the baffle and the dust trapping baffle are flexible materials, and they are fixed vertically on the conveyor belt . The upper side baffle blocks the high speed wind flow, . At the same time, the wind speed is gradually reduced by several dust catcher baffles, which can block the large particles of coal from falling into the belt, and the small particles of coal dust will fall back into the conveyor belt when it reaches the area of gentle wind speed, preventing the coal dust from mixing into the wind flow, improving the working environment and ensuring the safe production of the mine.
Conveyor cover for coal mine conveyor belt, including conveyor belt and adjusting wall , the conveyor belt passes through the belt hole of the adjusting wall, characterized in that: there is a transverse upper baffle fixed above the conveyor belt on both sides of the adjusting wall , there are side baffles fixed on both sides of the conveyor belt , the front end of the upper baffle and the side baffle There is a baffle fixed at the opening of the upper baffle and the front end of the side baffle , and a number of dust catching baffles are fixed at the rear side of the baffle at intervals, and the baffle and the dust catching baffle are both flexible materials and fixed vertically on the upper side of the conveyor belt .
