Dust cover for coal mine conveyor belt

Abstract

The invention discloses a dust cover for a coal mine conveying belt and belongs to the field of coal mine conveying belt windproof equipment. A transverse upper baffle (3) is fixed above the conveying belt (11) on the two sides of a baffler (6), side baffles (7) are fixed to the two sides of the conveying belt (11), and wind shields (14) are fixed to front end openings of the upper baffle (3) and the side baffles (7). Multiple dust catching baffles (10) are further fixed behind the wind shields (14) at intervals, and the wind shields (14) and the dust catching baffles (10) are made of flexible materials and vertically fixed to the upper side of the conveying belt (11). The wind shields are used for blocking high-speed wind flows, meanwhile, the dust catching baffles make wind speed decrease gradually, large-particle coal can be blocked and fall back on the belt, small-particle coal dust falls back on the conveying belt when reaching a zone which is slow in wind speed along with gradual decrease of wind speed, so that the coal dust is prevented from being mixed into wind flows, the windproof effect is good, the working environment is improved, and safety production of a coal mine is guaranteed.

Description

technical field

[0001] The utility model relates to a dustproof cover for a coal mine conveyor belt, which belongs to the field of windproof equipment for a coal mine conveyor belt. Background technique

[0002] In order to ensure personnel safety and production needs, an adjustment wall is built in the mine, and an adjustment window is set on the adjustment wall. The air volume is adjusted by changing the section of the adjustment window. According to the needs of mine transportation and ventilation, part of the conveyor belt needs to pass through the adjustment wall. When the air flow passes through the belt hole of the adjustment wall, the ventilation section suddenly becomes smaller, and the wind speed passing through the belt hole will increase. When the belt carries coal, the high-speed air flow will blow the coal out of the belt, and large particles of coal dust will be blown out of the belt. The accumulation near the wall needs to be cleaned manually, and small part...

Examples

Embodiment 1

[0026] refer to Figure 1~2 , the dust cover of the coal mine conveyor belt, including the adjustment wall 6 and the conveyor belt 11, the conveyor belt 11 passes through the belt hole 601 of the adjustment wall 6, and the conveyor belt 11 on both sides of the adjustment wall 6 is fixed with a horizontal upper baffle 3, Both sides are fixed with side baffle 7, and the front end opening of upper baffle 3 and side baffle 7 is fixed with windshield 14, and the back side of windshield 14 is also fixed with a plurality of dust catch baffles 10, and windshield 14 and The dust-catching baffles 10 are made of flexible materials, and are vertically fixed on the upper side of the conveyor belt 11. The direction of the arrow in the figure is the transmission direction of the conveyor belt 11. Wind speed can become bigger, and wind deflector 14 blocks high-speed wind flow, but because wind speed is very fast, still can be blown in the space that upper baffle plate 3 and side baffle 7 form...

Embodiment 2

[0033] refer to Figure 5 , the difference between this embodiment and Embodiment 1 is that the dust catch baffle 10 is an integral flexible material, and the bottom is wave-shaped. Deformation, so that large coals pass through the wavy depressions, prevent the formation of gaps, and improve the windproof effect of the dust-catching baffle 10. The windshield 14 can be a whole flexible material, or it can be made of multiple strips of rubber belts. Arrangement composition. Other structures are with embodiment 1.

Embodiment 3

[0035] refer to Image 6 , the upper baffle 3 and the side baffle 7 are made of hard materials, can adopt planks or iron plates, the side baffles 7 are directly fixed on both sides of the conveyor belt 11, and the upper baffle 3 is fixed on the top of the side baffles 7, The windshield 14 and the dust catch baffle 10 are made of flexible material, and the upper end is fixed on the upper baffle 3 . The upper baffle plate 3 and the side baffle plate 7 can be longitudinal splicing structures respectively, and the length can be adjusted to meet the needs of different mines.
