TECHNICAL FIELD

[0001] The utility model relates to dust falling technology field, concretely is a kind of mining tunneling dust falling equipment. BACKGROUND

[0002] In the process of mining tunneling, a large amount of dust will be generated, which not only affects the health of miners, leading to the occurrence of occupational diseases such as pneumoconiosis, but also reduces the visibility in the mine, increasing the probability of safety accidents.

Since the dust spreads too fast and the spreading area is too wide, it is impossible to quickly complete dust reduction by relying on a few devices, and the dust will still spread, ultimately resulting in poor actual dust reduction effect.

After the pull-out wind screen 11 is lifted, it can intercept and filter dust generated in the mining tunneling area. The mining tunneling dust reduction device can lift the pull-out wind screen 11, intercept and filter dust generated in the mining tunneling area, and avoid further dust dispersion during the dust reduction process. In addition, the height of the pull-out wind screen 11 can be freely adjusted, which is more flexible in application.

[0037] As Figures 5 to 6 ​​As shown, the lifting assembly comprises a fixed cylinder 12, a plurality of movable lifting rods 13 are interference fitted in the fixed cylinder 12, the top end of the lifting rod 13 is welded with a Y-shaped bracket 14, the top of the pull-out wind screen 11 is bonded with a horizontal supporting rod 15, the horizontal supporting rod 15 is lifted by the two Y-shaped brackets 14.
