Description

Technical Field

[0001] The utility model relates to the technical field of open-pit mining, and more specifically, to a dust removal device for open-pit mining. Background Art

[0002] A large amount of dust is generated during mining. In order to reduce the impact on the health of workers, dust removal devices are usually used to remove dust. During the use of existing open-pit mining dust removal devices, water mist is usually sprayed out through a spray head to reduce dust in the air. The water mist sprayed by the spray head diffuses slowly, making the spraying range small, thereby reducing the dust removal efficiency of the entire device; secondly, during the use of existing open-pit mining dust removal devices, the position of the spray head is usually fixed. When the direction of the spray head needs to be changed, the entire device needs to be rotated to change the direction of the spray head spray, which is time-consuming and labor-intensive, and very inconvenient to use.

[0031] In this embodiment, the pump body 12 is started, and the pump body 12 transports the water in the water tank 13 to the water inlet pipe 10 through the hose 11, and then enters the spray shell 1, and finally sprays out from the multiple spray heads 2 to reduce the dust generated by open-pit mining.

[0033] See also Figure 1-5 As an implementation method for adjusting the angle of the adjustment seat 15: a moving groove 18 is provided on the rotating plate 16, and a first screw 19 is rotatably provided in the moving groove 18, one end of the first screw 19 passes through the rotating plate 16 and is fixedly connected to a second motor 20 fixedly provided on one side of the rotating plate 16, a moving seat 21 is threadedly connected to the first screw 19, a support rod 22 is hingedly connected between the moving seat 21 and the adjustment seat 15, a third motor 23 is fixedly provided at the lower end of the lifting frame 17, and a driving end of the third motor 23 passes through the lifting frame 17 and is fixedly connected to the rotating plate 16.

[0034] Specifically, the second motor 20 is started, and the second motor 20 drives the first screw 19 to rotate. Since the first screw 19 is threadedly connected to the moving seat 21, the moving seat 21 moves along the moving groove 18, and the moving seat 21 drives the support rod 22 to rotate. At the same time, the support rod 22 pushes the adjustment seat 15 to rotate around the hinged connection with the rotating plate 16, thereby adjusting the up and down angles of the adjustment seat 15.

A second screw 26 is rotatably connected between the bracket 25 and the base 14, and the lower end of the second screw 26 passes through the base 14 and is fixedly connected to a fourth motor 27, and a lifting seat 28 is threadedly connected to the second screw 26, and both ends of the lifting seat 28 pass through the bracket 25 and are fixedly connected to the lifting frame 17.

[0036] Specifically, the fourth motor 27 is started, and the fourth motor 27 drives the second screw 26 to rotate, so that the lifting seat 28 drives the bracket 25 to move upward, the lifting seat 28 drives the lifting frame 17 to move upward, and the lifting frame 17 drives the rotating plate 16, the adjustment seat 15, the air inlet pipe and the spray shell 1 to move upward, thereby driving the multiple spray heads 2 to move upward, thereby adjusting the height of the spray head 2.

[0037] To sum up, when the overall equipment is in use:

[0038] When it is necessary to expand the range of the spray, a roller is provided at the lower end of the base 14, which can move the entire device according to the use requirements, and the pump body 12 is started. The pump body 12 transports the water in the water tank 13 to the water inlet pipe 10 through the hose 11, and then enters the spray shell 1, and finally sprays it from multiple spray heads 2 to reduce the dust generated by open-pit mining. At the same time, the first motor 8 is started, and the first motor 8 drives the driving gear 9 to rotate, and the driving gear 9 drives the gear ring 7 to rotate around the rotating connection with the spray shell 1, and the gear ring 7 drives multiple driven gears 6 to rotate, and the driven gear 6 drives the rotating rod 4 to rotate, and the rotating rod 4 drives the fan blades 5 to rotate.

At the same time, the support rod 22 pushes the adjustment seat 15 to rotate around the hinged connection with the rotating plate 16, so as to adjust the up and down angles of the adjustment seat 15, and the third motor 23 is started, and the third motor 23 drives the rotating plate 16 to rotate, and the rotating plate 16 drives the adjustment seat 15 to rotate, so as to adjust the left and right angles, and the adjustment seat 15 drives the water inlet pipe 10 and the spray shell 1 to rotate, so as to adjust the up and down angles and left and right angles of the spray head 2.

[0040] When the height of the spray head 2 needs to be adjusted, the fourth motor 27 is started, and the fourth motor 27 drives the second screw 26 to rotate, so that the lifting seat 28 drives the bracket 25 to move upward, the lifting seat 28 drives the lifting frame 17 to move upward, and the lifting frame 17 drives the rotating plate 16, the adjustment seat 15, the air inlet pipe and the spray shell 1 to move upward, thereby driving the multiple spray heads 2 to move upward, so as to adjust the height of the spray head 2. A controller is provided on the base 14, and the entire device is controlled by the controller.
