[0001] The utility model relates to the technical field of dust suppression devices, in particular to a spray dust suppression device used for mining. Background Art

[0002] A large amount of dust is generated during underground mining operations. In order to ensure the safety of on-site personnel and improve the on-site environment, dust reduction treatment is required.

[0003] In the prior art, there is a coal dust suppression device for coal mining and excavation, such as the application number CN202322639590.X, which includes a support rod arranged on the ground and an elastic tube with a spray head installed on the upper end thereof, and an arc adjustment assembly slidably arranged in the middle of the support rod, and diagonal support rods connected to the arc adjustment assembly are provided at both ends of the elastic tube. When in use, the support rod is placed in the middle position of the tunnel ground, and the operator manually adjusts the arc adjustment assembly to move up and down along the support rod, driving the diagonal support rod to pull the elastic tube to bend or unfold, so as to adjust it to match coal tunnels of different specifications. However, since the dust suppression device is arranged on the ground of the tunnel, the support rod and diagonal support rod supporting the elastic tube, and the arc adjustment assembly for adjusting the curvature of the elastic tube, will occupy most of the passage space of the tunnel when used in combination, seriously affecting the passage of transport vehicles and pedestrians.

After the elastic tube is bent into place, use the hand that rotates the shaft to twist the locking piece to lock the shaft. At this time, the elastic tube remains in the bent or expanded state. Finally, several nozzles on the elastic tube are controlled to start spraying and dust reduction. The adjustment mechanism is compact in design and only occupies the space at the top of the tunnel, thereby increasing the passage space on the tunnel ground and facilitating the passage of transport vehicles and pedestrians.

[0008] As a further implementation:

[0009] A blocking plate is also provided in the installation box, the rotating shaft passes through the blocking plate, and the two steel wire ropes are respectively wound on the rotating shafts on both sides of the blocking plate, so that the two steel wire ropes each have an independent winding space to prevent the two steel wire ropes from interfering with each other or getting tangled.

The pipe hoops 5 are detachably connected to the elastic tube 1 by bolts, which facilitates the replacement of the position of the elastic tube 1 so as to adjust the elastic member to different curvatures.

[0025] The structure of the adjustment mechanism 2 is combined with Figure 2 Specifically, the adjustment mechanism 2 mainly includes a mounting box 21 , a rotating shaft 22 , two steel wire ropes 23 and a blocking plate 211 .

[0026] The following is a detailed introduction to the various structures of the adjustment mechanism 2:

[0027] The installation box 21 is a rectangular box, including a box body and an upper cover, and the upper cover is detachably connected to the box body, so that the installation box 21 can be opened conveniently to maintain the components therein.

[0028] The blocking plate 211 is transversely arranged in the middle of the box body. The blocking box divides the box body into two independent spaces. Both ends of the box body and the blocking plate 211 are provided with interconnected through holes.

[0029] The rotating shaft 22 is a T-shaped shaft, the diameter of one end with a larger diameter is larger than the diameter of the through hole, and the end with a smaller diameter is provided with an external thread. The end with the small diameter passes through the box body through the through hole, and the part passing through the box body is provided with a locking piece, which can be a locking nut. The rotating shaft 22 is locked on the end side wall of the box body through the locking nut.

[0030] The inner ends of the two steel wire ropes 23 are respectively wound around the rotating shafts 22 on both sides of the blocking plate 211. Through the blocking plate 211, the two steel wire ropes 23 each have an independent winding space, which can prevent the two steel wire ropes 23 from interfering with each other or getting knotted, and the winding directions of the two steel wire ropes 23 are the same. The outer ends of the two steel wire ropes 23 extend from both sides of the box body respectively, and are finally connected to the two pipe clamps 5 respectively. By rotating the rotating shaft 22, the two steel wire ropes 23 can be moved in opposite directions at the same time, and then the elastic tube 1 is evenly bent or unfolded to achieve the adjustment of the bending curvature to match tunnels of different specifications. The structural design of the adjustment mechanism 2 is compact, and the entire device only occupies the space on the top of the tunnel, thereby increasing the passage space on the tunnel ground and facilitating the passage of conveying vehicles and pedestrians.

[0031] Regarding the connection structure between the hook 3 and the elastic tube 1, Figure 2 Specifically, a first connecting piece is provided on the elastic tube 1, and the hook 3 is connected to the first connecting piece through a first ring 4.

The specifications of the first circular ring 4 and the second circular ring 6 are also designed to be the same to improve versatility.

[0034] When in use, the elastic tube 1 is first fixed, for example, the elastic tube 1 is hung on the steel mesh on the side wall of the tunnel that is within the reach of the operator through the hook 3, and then the operator holds the installation box 21 with one hand, and then rotates the shaft 22 with the other hand. At this time, the two steel wire ropes 23 can move in opposite directions at the same time, and then the elastic tube 1 is evenly bent or unfolded to achieve the adjustment of the bending curvature. After the elastic tube 1 is bent to match the specifications of the tunnel in use, the hand that rotates the shaft 22 is used to twist the locking piece to lock the shaft 22. At this time, the elastic tube 1 remains in the bent or unfolded state, the hook 3 is removed from the steel mesh on the side wall of the tunnel, and the elastic tube 1 is hung on the steel mesh at the top of the tunnel through the hook 3. Finally, the elastic tube 1 is connected to the pipeline of the spray water, so that several nozzles on the elastic tube 1 start spraying and dust reduction work.
