Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example

[0030] At present, most of the dust treatment equipment at construction sites includes water pipes, pressure pumps and nozzles. The water pipes form a waterway, and the pressure pump is used to spray water to the surrounding area through the water pipes and nozzles to achieve the purpose of dust suppression. However, in the process of water spraying, since the nozzle itself is fixed on the equipment, the direction of the water spraying of the nozzle is usually fixed. Therefore, the spraying range of the nozzle is relatively limited, the uniformity is poor, the dust suppression efficiency is reduced, and it is difficult to maintain the dust suppression effect continuously;

[0031] Therefore, please refer to Figure 2 and Figure 3 As shown, the purpose of this embodiment is to provide a dust prevention device, which includes an equipment box 1 and a spraying mechanism 12, and the spraying mechanism 12 is installed on the top of the equipment box 1. In order to realize the spraying function, the spraying mechanism 12 includes a rotating table 22, and a water outlet chamber 24 is opened inside the rotating table 22. A plurality of spraying pipes 25 connected to the water outlet chamber 24 are fixed on the outside of the rotating table 22, and a plurality of atomizing nozzles 26 connected to the water outlet chamber 24 are provided on the surface of the spraying pipe 25; the equipment box 1 includes a water storage tank 8, and the water storage tank 8 is installed inside the equipment box 1, wherein a water pump 9 is installed at the bottom of the inner side of the water storage tank 8, and a water suction pipe 10 is fixedly connected to the side of the water pump 9, and a delivery pipe 11 is provided between the water pump 9 and the water outlet chamber 24; start the water pump 9, use the water suction pipe 10 to pump out the water in the water storage tank 8 and input it into the water outlet chamber 24 through the delivery pipe 11, and finally the water is sprayed out by the atomizing nozzle 26 on the surface of the spraying pipe 25, thereby realizing spraying.

[0032] In order to improve the spraying range and uniformity of the atomizing nozzle 26, a rotating gear ring 21 is fixed at the bottom of the rotating platform 22; an adjusting gear 20 is meshed on one side of the rotating gear ring 21, and a transmission rod 19 is fixed on the side of the adjusting gear 20 away from the rotating platform 22; a driving motor 3 is installed at the bottom of the outer side of the water storage tank 8, and a driving gear 6 is fixed on the output shaft of the driving motor 3; a transmission gear 16 is meshed on the outer side of the driving gear 6, and a stirring rod 17 that passes through the bottom of the water storage tank 8 is fixed on one side of the transmission gear 16, and the end of the stirring rod 17 away from the transmission gear 16 is connected to the transmission gear 16. A conveyor belt 4 is provided between the rods 19; the drive motor 3 is started, and the output shaft of the drive motor 3 rotates, driving the drive gear 6 to rotate, thereby driving the transmission gear 16 meshing with the drive gear 6 and the stirring rod 17 fixed to one side of the drive gear 6 to rotate, and the stirring rod 17 drives the transmission rod 19 to rotate through the conveyor belt 4, and then drives the adjustment gear 20 and the rotating gear ring 21 to rotate, and finally drives the rotating table 22 to rotate. When spraying, the spray pipe 25 drives the atomizing nozzle 26 to rotate, and the rotation inertia is used to expand the spraying range and improve the uniformity of the spraying;

[0033] The improvement of this embodiment is that the output shaft of the driving motor 3 rotates, and the rotating table 22 is driven to rotate through linkage, so that the spraying pipe 25 can rotate during spraying, and the rotation inertia is used to expand the spraying range, and at the same time, the uniformity of spraying is improved, and the dust particles in the air are effectively adsorbed and settled, which greatly reduces the dust concentration and improves the work efficiency.

[0034] Since the rotating table 22 needs to rotate on the top of the equipment box 1, and at the same time cannot affect the entire waterway connection and gear transmission, a support column 23 that penetrates the rotating gear ring 21 is rotatably connected between the rotating table 22 and the equipment box 1, and the delivery pipe 11 penetrates the support column 23 and is connected to the water outlet chamber 24; by setting the support column 23, the support column 23 is used to penetrate the rotating gear ring 21, and at the same time, the top outer side of the support column 23 rotates with the rotating table 22, and the support column 23 is provided with a through groove, so that the support column 23 and the rotating table 22 can rotate and the waterway connection can be met without affecting the gear transmission;

[0035] Considering that the dust at the bottom of the equipment box 1 is difficult to be sprayed by water mist, please refer to Figure 4 As shown, a dust collecting box 30 is provided at the bottom of the inner cavity of the equipment box 1, and a dust suction port 29 is provided on a side of the dust collecting box 30 away from the water storage tank 8. A cleaning mechanism 2 is provided in the dust collecting box 30, and the cleaning mechanism 2 includes a rotating rod 27 and a dust suction fan 28, and the dust suction fan 28 is installed in the dust suction port 29; a conveyor belt 4 is connected between the rotating rod 27 and the output shaft of the driving motor 3; the dust suction fan 28 is driven to rotate by the rotation of the output shaft of the driving motor 3, thereby generating suction force, and the dust at the bottom of the equipment box 1 is sucked into the dust collecting box 30;

[0036] Since there is still a situation where some dust falls on the ground but cannot be sucked up by the cleaning mechanism 2, a hydraulic telescopic rod 31 is further provided at the bottom of the outer side of the water storage tank 8, a return spring 33 is provided at the bottom of the inner cavity of the equipment box 1, a pressure rod 32 is provided between the hydraulic telescopic rod 31 and the return spring 33, and the end of the pressure rod 32 away from the return spring 33 is rotatably connected to a cleaning rod 34, and a driving shaft 5 is fixed to the output shaft of the driving motor 3, and a conveyor belt 4 is connected between the driving shaft 5 and the cleaning rod 34, and a cleaning disc 35 is fixedly connected to the end of the cleaning rod 34 away from the pressure rod 32; by providing the driving shaft 5 to increase the length of the output shaft of the driving motor 3, when the output shaft of the driving motor 3 rotates, the driving shaft 5 is driven to rotate, thereby driving the cleaning rod 34 to rotate through the conveyor belt 4, so that the dust at the bottom of the equipment box 1 is lifted up by the cleaning disc 35, and is cleaned by the cleaning mechanism 2;

[0037] In order to facilitate the movement of the entire device and improve the scope of use of the device, please refer to Figure 1As shown, a moving wheel 13 is provided at the bottom of the equipment box 1, and a moving handle 14 is provided on one side of the equipment box 1. The equipment can be pushed at any time by the moving handle 14 and the moving wheel 13, thereby indirectly improving the dust reduction range; at the same time, in order to facilitate the control of the entire equipment, the equipment box 1 is provided with a control panel 15 adjacent to the moving handle 14, and the control panel 15 is used to achieve precise control of various components of the equipment, and the operation is simple; at the same time, a water inlet is provided on the top of the equipment box 1, which is convenient for replenishing water to the water storage tank 8;

[0038] It should be further explained that, in order to improve the dust reduction efficiency, dust reduction agents are usually added to the water tank 8 and mixed with water, which needs to be fully stirred. Therefore, a stirring assembly 7 is provided in the water tank 8, and the stirring assembly 7 includes a plurality of stirring blades 18 fixed to the surface of a stirring rod 17. The stirring rod 17 is rotated by the output shaft of the driving motor 3, and a plurality of stirring blades 18 are used to increase the stirring force and range, so that the dust reduction agent is mixed with water. Considering the size of the water tank 8 and the improvement of the stirring efficiency, the number of stirring rods 17 in this example is two, of which only one stirring rod 17 is rotatably connected to the transmission rod 19 through the conveyor belt 4.

[0039] In summary, the working principle of this solution is as follows:

[0040] First, fill the water tank 8 with water through the water inlet, then push the moving handle 14 to move the device to the designated position, and then start the driving motor 3 by setting the control panel 15. The driving motor 3 drives the transmission gear 16 to rotate through the driving gear 6, so that the stirring rod 17 drives the stirring blade 18 to rotate, and the water in the water tank 8 and the dust suppressant are evenly mixed. After the mixing is even, the water pump 9 is turned on, and the water pump 9 sucks out the evenly mixed water through the suction pipe 10, and conveys it into the water outlet chamber 24 in the rotating table 22 through the conveying pipe 11. The water in the water outlet chamber 24 then enters the spraying pipe 25, and finally is evenly sprayed out through the atomizing nozzle 26 for dust reduction. At the same time, a stirring rod 17 is connected to the transmission rod 19 in transmission, and the adjusting gear 20 on the transmission rod 19 is meshed with the rotating gear ring 21. The rotating gear ring 21 drives the rotating table 22 on the support column 23 to rotate, so that the spraying pipe 25 sprays more evenly. In addition, the hydraulic telescopic rod 31 presses down the pressure rod 32 before the drive motor 3 is started, so that the cleaning disc 35 contacts the ground. The drive shaft 5 drives the dust suction fan 28 and the cleaning disc 35 to rotate, sweeping the dust on the ground and sucking it into the dust collecting box 30 to prevent the dust on the ground from being brought up again. After the equipment is used, the drive motor 3 is turned off first, and then the hydraulic telescopic rod 31 is adjusted to lift the cleaning disc 35 off the ground through the return spring 33.

[0041] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0042] Therefore, the above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application; that is, all equivalent changes made according to the scope of the claims of the present application are within the protection scope of the claims of the present application.
