[0003] Dust control nets used in blasting operations can only provide vertical dust control, but when an explosion occurs, smoke and dust rise everywhere, and the top of the net lacks protection, making it easy for dust to spread from the top, thus limiting the dust control area.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3 The present invention provides the following technical solution:

[0018] Example 1: An explosive composite dust suppression device includes a support column 1, with a first dustproof net 2 fixedly connected between the support columns 1, a mounting base 3 fixedly connected to the side wall of each support column 1, a second dustproof net 4 rotatably connected to each mounting base 3, a torsion spring 5 fixedly connected to the top and bottom of the output shaft of the second dustproof net 4, a fixing column 6 fixedly connected to the bottom of each support column 1, a support rod 7 rotatably connected to the back wall of each support column 1, and the bottom of each torsion spring 5 fixedly connected to the top of the corresponding mounting base 3.

[0019] When in use, the dust suppression device can be placed around the explosion area, the bottom fixing column 6 of the support column 1 can be inserted into the ground, and the two support rods 7 can be rotated to abut against the ground on the back of the support column 1. The smoke and dust from the explosion will be blocked and filtered by the first dustproof net 2 and the second dustproof net 4. At the same time, the impact of the explosion will also cause the two second dustproof nets 4 to rotate backward. When the second dustproof nets 4 rotate, their output shafts will twist the torsion springs 5.

[0020] Example 2: The technical solution of this example that differs from Example 1 includes: the back wall of the second dustproof net 4 is fixedly connected with an extrusion rod 8, and the support column 1 is provided with an atomizing mechanism 9. The atomizing mechanism 9 includes a switch 91, a receiving groove 92 and a conveying pipe 93. The bottom of the receiving groove 92 is fixedly installed with a hydraulic cylinder 94. The top of the output end of the hydraulic cylinder 94 is fixedly connected with a sealing plate 95. The top of the conveying pipe 93 is fixedly connected with a water collection tank 96. Multiple atomizing nozzles 97 are fixedly connected to the water collection tank 96.

[0021] All switches 91 are located on the back wall of the support column 1. All receiving slots 92 are located inside the support column 1. All conveying pipes 93 are fixedly connected to the top of the support column 1. All conveying pipes 93 are connected to the corresponding receiving slots 92. All conveying pipes 93 are connected to the water collection tank 96. All sealing plates 95 are slidably connected inside the receiving slots 92. Sealing gaskets are provided on the outer wall of the sealing plates 95. All atomizing nozzles 97 are connected to the water collection tank 96. All front walls of the support column 1 are fixedly connected to water inlets. All front walls of the support column 1 are fixedly connected to handles at the bottom of the corresponding water inlets. All water inlets are connected to the corresponding receiving slots 92.

[0022] In use, when the second dustproof net 4 is pushed backward and rotates, it will drive the squeezing rod 8 to rotate as well. During the rotation, the squeezing rod 8 will press the switch 91 on the support column 1. The pressure on the switch 91 will activate the corresponding hydraulic cylinder 94. The output end of the hydraulic cylinder 94 will extend upward and drive the sealing plate 95 to move upward inside the receiving tank 92. The moving sealing plate 95 will cause the water at the top of the receiving tank 92 to be transported to the inside of the water collection tank 96 through the conveying pipe 93. As the sealing plate 95 continues to move upward, the water inside the water collection tank 96 will be sprayed in large quantities onto the top of the water collection tank 96 through the atomizing nozzle 97, thereby settling the dust on the top of the first dustproof net 2 and the second dustproof net 4. The first dustproof net 2 and the second dustproof net 4 form a multi-layer composite dust suppression, improving its dust suppression effect and practicality. After use, the output end of the hydraulic cylinder 94 can be manually reset by using the switch 91, and then water can be added into the receiving tank 92 through the water inlet.
