[0032] Please refer to Figure 1 In a specific embodiment, the dust suppression device 1 of the sweeper provided by the specific embodiment of the utility model includes a water spray pipe 102, a nozzle 103, a fixing frame 101, a water storage device 107 and a water pump 106. Along the moving direction of the sweeper, the water spray pipe 102 is arranged in front of the sweeping brush 2 of the sweeper. Preferably, there is a distance between the water spray pipe 102 and the sweeping brush 2 so that the road surface is fully wetted. The sweeping brush 2 can be a disc sweeping brush. In this application, the moving direction of the sweeper is taken as the front, and the moving direction of the sweeper is the moving direction of the sweeper in the normal form of cleaning work.

[0033] The nozzle 103 is installed on the water spray pipe 102 to spray water downward to form a spray water curtain 104. Specifically, one nozzle 103 can be set on the water spray pipe 102, and the dust reduction device 1 is provided with multiple water spray pipes 102. Multiple nozzles 103 can also be provided on the water spray pipe 102, and the nozzles 103 on the water spray pipe 102 are arranged in sequence along the width of the sweeper. In this case, the dust reduction device 1 can only be provided with one water spray pipe 102. Specifically, 2-5 nozzles 103 can be arranged in sequence on the water spray pipe 102, and preferably, two adjacent nozzles 103 are arranged at equal intervals. In order to improve the dust reduction effect, it is preferred that the spray water curtain 104 formed at the bottom ends of two adjacent nozzles 103 intersect to avoid that the local position of the working road surface is not wetted by the dust reduction water.

[0034] The spray water curtain 104 may be a fan-shaped structure with the nozzle 103 as the top and gradually expanding downward, and the fan surface of the fan-shaped structure is perpendicular to the moving direction of the sweeper, so that the minimum number of nozzles 103 is used and the maximum range of the working road surface is covered.

[0035] In order to make the nozzle 103 discharge liquid uniformly, preferably, the water pump 106 is connected to the water spray pipe 102 through the water inlet pipe 105, and the installation hole for connecting the water inlet pipe 105 and the water spray pipe 102 is located in the middle of the water spray pipe 102, and nozzles 103 are installed on both sides of the installation hole on the water spray pipe 102. Specifically, the number of nozzles 103 installed on both sides of the installation hole on the water spray pipe 102 is equal.

[0036] In order to facilitate the flow of dust suppression water, preferably, the water spray pipe 102 is a straight pipe extending along the width direction of the vehicle body. The width direction of the vehicle body is a horizontal direction perpendicular to the direction of travel of the sweeper. Specifically, the inner cavity of the water spray pipe 102 is a cylindrical tube structure, and the nozzle 103 extends along the axial direction of the cylindrical tube structure.

[0037] The fixing frame 101 is fixedly connected to the water spray pipe 102 and fixed to the body of the sweeper. Specifically, the fixing frame 101 can be installed on the chassis beam 3 of the vehicle body, and the water spray pipe 102 is located at a lower position at the front end of the chassis beam 3. The fixing frame 101 can be installed on the vehicle body by threaded fasteners, thereby facilitating the maintenance of the water spray pipe 102 and the nozzle 103.

[0038] In order to improve the installation stability of the water spray pipe 102, it is preferred that Figure 1 As shown, the fixing frame 101 includes at least two fixing rods, one end of which is fixedly connected to the water spray pipe 102, and the other end of which is fixed to the body of the sweeper. Specifically, the fixing rod is fixed to the chassis beam 3, and the fixing rods are arranged in sequence along the width of the sweeper.

[0039] The water storage device 107 is provided with a chamber for accommodating dust suppression water. The water pump 106 is used to transport the dust suppression water in the chamber to the water spray pipe 102. Specifically, the water storage device 107 can be a water tank. The water storage device 107 and the water pump 106 are both fixed to the vehicle body. In order to facilitate the dust suppression water in the water storage device 107 to flow smoothly to the nozzle 103, preferably, the water storage device 107 is arranged higher than the water spray pipe 102.

[0040] During installation, the water spray pipe 102 is installed on the body of the sweeper through the fixing frame 101. Specifically, the working mechanism of the dust reduction device 1 is as follows: dust reduction water is introduced from the water storage device 107, enters the water pump 106 through the connection water spray pipe 102, and the dust reduction water enters the water spray pipe 102 after being pressurized by the water pump 106. After being sprayed out from the nozzle 103, a spray water curtain 104 is formed to reduce dust on the working road surface.

[0041] By installing the dust reduction device 1 on the road sweeper, when sweeping the road along the traveling direction, the spray water curtain 104 pre-wet the dust on the working road surface first. When the disc brush passes through the working road surface and sweeps it, the dust has been fully wetted, and the dust is controlled to a certain extent, thereby improving the dust reduction effect of the road sweeper.

[0042] like Figure 2 As shown, the nozzle 103 is installed at the bottom end of the water spray pipe 102, and along the traveling direction of the cleaning vehicle, the spray water curtain 104 is located in front of the water spray port of the nozzle 103. That is, the spray water curtain 104 sprayed by the nozzle 103 is sprayed toward the front of the cleaning vehicle.

[0043] Considering that there may be obstacles on the road surface, in order to reduce the damage of the nozzle 103 by the obstacles, preferably, the dust suppression device 1 also includes a protective plate, which is fixedly connected to the fixing frame 101, and along the traveling direction of the sweeper, the protective plate is located directly in front of the nozzle 103. Specifically, the bottom end of the protective plate is lower than the bottom end of the nozzle 103, and the top end of the protective plate is higher than the top end of the nozzle 103.

[0044] Further, preferably, the top of the protective plate is higher than the water spray pipe 102, and both ends of the protective plate in the horizontal direction extend to the opposite ends of the water spray pipe 102 along the width direction of the cleaning vehicle, so that the protective plate can protect the water spray pipe 102 at the same time.

[0045] In order to facilitate the movement of the sweeper, preferably, the front of the guard plate is an arc-shaped guide surface protruding in the middle toward the front of the sweeper. When the sweeper moves, the obstacle slides along the arc-shaped guide surface to both sides of the sweeper, avoiding the situation where the sweeper pushes the obstacle to move forward.

[0046] In order to facilitate the control of the dust suppression device 1, preferably, the dust suppression device 1 also includes a switch module for controlling the operation of the water pump 106, and the switch module is installed in the operating room of the sweeper. Specifically, the switch module can be a traditional push switch or a touch switch, and the user controls the working state of the water pump 106 through the switch module.
