It solves the problem that existing dust suppression devices can only use clean water for dust suppression, and when the road environment is not suitable for using clean water for dust suppression, workers need to add dust suppressant for mixing, which affects the work efficiency of workers.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a road high-pressure spray dust suppression device, comprising a mobile vehicle and a box fixedly connected to the mobile vehicle, wherein the box is provided with a feeding and mixing mechanism for facilitating the mixing and dilution of the dust suppressant;

[0007] The feeding and mixing mechanism includes a liquid storage tank fixedly installed on the top of the box, a mixing tank fixedly installed inside the box, a delivery pump fixedly installed on the top of the box, the input end of the delivery pump being connected to the liquid storage tank, a delivery pipe extending into the mixing tank being fixedly connected to the output end of the delivery pump, an electromagnetic flow meter being fixedly installed on the outside of the delivery pipe, and a stirring frame being rotatably connected inside the mixing tank.

[0008] Furthermore, the liquid storage tank is equipped with a dust suppressant, and a feeding pipe extending into the tank is fixedly connected to the top of the liquid storage tank.

[0009] Furthermore, a drive motor is fixedly installed on the inner bottom wall of the box, and a transmission gear is fixedly connected to the output shaft of the drive motor. A driven gear that meshes with the transmission gear is rotatably connected to one side of the mixing tank, and the driven gear is fixedly connected to one end of the stirring frame.

[0010] Furthermore, a fixed base is fixedly connected to the top of the box, and a spray cannon is provided on the top of the fixed base. A rotation adjustment mechanism capable of driving the spray cannon to rotate is provided inside the fixed base.

[0011] Furthermore, the rotation adjustment mechanism includes a mounting base rotatably connected to the top of the fixed base, a hydraulic cylinder is disposed inside the fixed base, a rotating plate is rotatably connected inside the fixed base, a fixed block is fixedly connected to the bottom of the rotating plate, and the output end of the hydraulic cylinder is rotatably connected to the fixed block.

[0012] Furthermore, a rotating shaft is fixedly connected between the mounting base and the rotating plate, and the end of the hydraulic cylinder away from the fixed block is rotatably connected to the fixed base.

[0013] Furthermore, a support plate is fixedly connected to both the front and back of the top of the mounting base, and a connecting plate is fixedly connected between the two support plates. A connecting shaft is fixedly connected to both the front and back of the spray cannon, and the two connecting shafts are rotatably connected to the two support plates respectively.

[0014] Furthermore, a servo motor is fixedly mounted on the top of the connecting plate, a rotating disk is fixedly connected to the output shaft of the servo motor, and a mounting plate is fixedly connected to the outside of the connecting shaft.

[0015] Furthermore, a connecting block is fixedly connected to each side of the mounting plate and the rotating disk, and a connecting rod is rotatably connected between the two connecting blocks.

[0016] Furthermore, a hinge is fixedly connected between the spray cannon and the connecting plate, and a telescopic support rod is hinged between the two hinges.

[0017] Compared with the prior art, this utility model provides a road high-pressure spray dust suppression device, which has the following beneficial effects:

[0018] 1. This high-pressure spray dust suppression device for roads, by setting up a storage tank and a delivery pump, can transport the dust suppressant inside the storage tank to the mixing tank through a delivery pipeline. Then, by setting up a drive motor to drive the transmission gear and driven gear to rotate, it can drive the mixing frame to rotate, thereby diluting and mixing the dust suppressant. This allows for spray dust suppression treatment in different road environments, resulting in better dust suppression effect. At the same time, by setting up an electromagnetic flow meter, the amount of dust suppressant added can be monitored to avoid over-addition.

[0019] 2. This high-pressure spray dust suppression device for roads uses a hydraulic cylinder and a fixed block. The hydraulic cylinder can drive the fixed block and the rotating plate to rotate, which in turn drives the spray cannon to rotate. At the same time, because the output angle of the hydraulic cylinder is limited, the angle of the spray cannon can be restricted, preventing the pipe from getting tangled. This solves the problem that existing dust suppression devices can only use clean water for dust suppression. When the road environment is not suitable for using clean water for dust suppression, workers need to add dust suppressant to mix it, which affects the work efficiency of the workers.

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.

[0029] Please see Figures 1 to 4 This embodiment of a road high-pressure spray dust suppression device includes a mobile vehicle 1 and a housing 2 fixedly connected to the mobile vehicle 1. The housing 2 is equipped with a feeding and mixing mechanism for facilitating the mixing and dilution of dust suppressants. The feeding and mixing mechanism includes a liquid storage tank 3 fixedly installed on the top of the housing 2. A mixing tank 4 is fixedly installed inside the housing 2. A delivery pump 5 is fixedly installed on the top of the housing 2. The input end of the delivery pump 5 is connected to the liquid storage tank 3. A delivery pipe 6 extending into the mixing tank 4 is fixedly connected to the output end of the delivery pump 5. An electromagnetic flow meter 7 is fixedly installed on the outside of the delivery pipe 6. A stirring frame 8 is rotatably connected inside the mixing tank 4.

[0030] Specifically, the storage tank 3 is equipped with a dust suppressant, and a feeding pipe extending into the storage tank 3 is fixedly connected to the top of the storage tank 3. A drive motor 9 is fixedly installed on the inner bottom wall of the tank body 2. A transmission gear 10 is fixedly connected to the output shaft of the drive motor 9. A driven gear 11 that meshes with the transmission gear 10 is rotatably connected to one side of the mixing tank 4. The driven gear 11 is fixedly connected to one end of the stirring frame 8.

[0031] It should be noted that the mixing tank 4 is filled with clean water. By setting up a storage tank 3 and a delivery pump 5, the dust suppressant in the storage tank 3 can be delivered to the mixing tank 4 through the delivery pipe 6. Then, by setting up a drive motor 9 to drive the transmission gear 10 and the driven gear 11 to rotate, the mixing frame 8 can be rotated to dilute and mix the dust suppressant. This allows for spray dust suppression treatment in different road environments, resulting in better dust suppression effect.

[0032] Please see Figure 2 , Figure 5 and Figure 6In this embodiment, a fixed base 12 is fixedly connected to the top of the housing 2, and a spray cannon 13 is provided on the top of the fixed base 12. A rotation adjustment mechanism capable of driving the spray cannon 13 to rotate is provided inside the fixed base 12. The rotation adjustment mechanism includes a mounting base 14 rotatably connected to the top of the fixed base 12. A hydraulic cylinder 15 is provided inside the fixed base 12. A rotating plate 16 is rotatably connected inside the fixed base 12. A fixed block 17 is fixedly connected to the bottom of the rotating plate 16.

[0034] It should be noted that by setting up the hydraulic cylinder 15 and the fixed block 17, the hydraulic cylinder 15 can push the fixed block 17 and the rotating plate 16 to rotate, thereby driving the spray cannon 13 to rotate. At the same time, since the output angle of the hydraulic cylinder 15 is limited, the angle of the spray cannon 13 can be limited to avoid the pipe from getting tangled.

A hinge is fixedly connected between the spray cannon 13 and the connecting plate 19, and a telescopic support rod is hinged between the two hinges.

[0037] It should be noted that by setting the servo motor 22 to drive the rotating disk 23 to rotate, the connecting rod 25 can be driven to rotate. Then, by setting the mounting plate 21, the connecting rod 25 can drive the connecting shaft 20 to rotate back and forth, thereby adjusting the longitudinal angle of the spray cannon 13.

[0038] The working principle of the above embodiments is as follows:

[0039] First, the staff drives the mobile vehicle 1 and then moves it on the road. At this time, the delivery pump 5 is started to deliver the dust suppressant inside the storage tank 3 to the mixing tank 4. At the same time, the drive motor 9 is started to drive the mixing frame 8 to rotate. Then, the spray cannon 13 sprays the liquid inside the mixing tank 4 outward. During the spraying process, the hydraulic cylinder 15 is started to drive the spray cannon 13 to rotate. At the same time, the servo motor 22 is started to drive the spray cannon 13 to rotate longitudinally, thereby adjusting the dust suppression angle of the spray cannon 13.
