[0021] In this embodiment, a water tank 4 is fixedly installed at the rear end of the road sweeper body 1, and a garbage collection box 5 is hinged at the top of the water tank 4. Telescopic drive rods 6 for dumping garbage are respectively connected between the two sides of the water tank 4 and the garbage collection box 5, and the garbage collection box 5 is arranged between the water tank 4 and the driving operation position of the road sweeper body 1, that is, the garbage collection box 5 is between the cab and the water tank 4. The telescopic drive rod 6 is an electric telescopic rod and the control end is arranged on the operation control panel in the cab. A garbage dumping port is provided at the top of the garbage collection box 5, and a port cover plate 7 is hinged on the garbage dumping port, and the garbage dumping port is arranged near the hinge between the garbage collection box 5 and the water tank 4. When cleaning garbage, the port cover plate 7 blocks the garbage dumping port to avoid dust from there. After being used for a period of time, the two telescopic driving rods 6 can be started to lift the garbage collection box 5 so that it can be flipped along the hinge with the water tank 4. During the flipping process, the port cover 7 naturally droops due to its own gravity, opening the garbage dumping port, thereby realizing the dumping and unloading of garbage.

[0022] A garbage absorption pipe is connected between the garbage collection box 5 and the garbage collection device 3, and the garbage absorption pipe is used to absorb the garbage collected by the cleaning brush device 2 into the garbage collection box 5. Specifically, the garbage absorption pipe includes an outer absorption pipe section 8 arranged outside the garbage collection box 5 and an inner absorption pipe section 9 arranged inside the garbage collection box 5. One end of the outer absorption pipe section 8 is connected to the garbage collection device 3 and the other end is detachably connected to the garbage collection box 5. The inner absorption pipe section 9 penetrates the garbage collection box 5 and is connected to the outer absorption pipe section 8. When dumping garbage, the outer absorption pipe section 8 is separated from the garbage collection box 5, and it can be installed and reset after dumping. The outer absorption pipe section 8 is configured as a hose to facilitate disassembly and assembly operations.

[0023] The road sweeper body 1 is also equipped with a negative pressure forming device and a water mist spraying device for forming negative pressure in the garbage collection box 5. The air inlet of the negative pressure forming device is arranged in the garbage collection box 5, and the air outlet of the negative pressure forming device is arranged at the bottom of the road sweeper body 1, which is used to suck out the air in the garbage collection box 5 to form a negative pressure inside it, so as to suck the garbage into the garbage collection box 5 through the garbage absorption pipe. A wind direction adjusting device is installed at the air outlet of the negative pressure forming device, which is used to adjust the wind direction to adjust the impact intensity and angle of the high-pressure wind on the ground. The water inlet end of the water mist spraying device is connected to the water storage tank 4, and the water outlet end of the water mist spraying device is distributed on the cleaning brush device 2, in the garbage absorption pipe and on the air outlet of the negative pressure forming device, so as to form a spray-like water mist in multiple places to avoid the generation of dust during operation.

[0024] The negative pressure forming device includes a negative pressure suction pipe 10 arranged outside the garbage collection box 5, and the suction end of the negative pressure suction pipe 10 is arranged in the garbage collection box 5 and connected to a garbage filter plate 11, that is, the garbage filter plate 11 is arranged at the air inlet of the negative pressure suction pipe 10, which is used to intercept the light garbage sucked up by the negative pressure in the garbage collection box 5 to prevent it from entering the negative pressure suction pipe 10. The inner absorption pipe section 9 is set as a hard pipe and is gradually tilted from front to back in the garbage collection box 5. The inner absorption pipe section 9 extends to the rear side of the garbage filter plate 11 and an inclined discharge port is provided at the bottom of the rear end. Even if the position of the garbage entering the garbage collection box 5 is moved back as much as possible, and the discharge port is close to and away from the garbage filter plate 11, the two are staggered as much as possible to reduce the probability of light garbage floating up with the airflow.

[0025] The air outlet end of the negative pressure suction pipe 10 is connected to the negative pressure suction fan 12 fixedly mounted on the road sweeper body 1, and the negative pressure suction pipe 10 and the air inlet of the negative pressure suction fan 12 are detachable, and a sealing ring can be set at the connection between the two to improve the sealing of the high-pressure air path. When the dumping task of the garbage collection box 5 is implemented, the negative pressure suction pipe 10 will rotate synchronously with the garbage collection box 5, and automatically separate from the connection with the negative pressure suction fan 12 during the rotation transfer process; when the garbage is dumped, the negative pressure suction pipe 10 will return to its original position synchronously with the garbage collection box 5, and automatically fit onto the air inlet of the negative pressure suction fan 12, and can use the provided sealing ring to cooperate with the weight of the garbage collection box 5 to maintain the sealing of the connection between the two. The air outlet of the negative pressure suction fan 12 is connected to an air outlet hose 13, the wind direction adjustment device is arranged at the port of the air outlet hose 13, and the air outlet of the air outlet hose 13 is arranged on the rear side of the garbage collection device 3, so as to discharge the air in the garbage collection box 5.

[0026] The water mist spraying device includes a water mist spraying pump 14 fixedly mounted on the road sweeping vehicle body 1, a water mist spraying nozzle 15 arranged in the inner absorption pipe section 9, the cleaning brush device 2 and the air outlet hose 13, and each of the water mist spraying nozzles 15 and the water mist spraying pump 14, and the water mist spraying pump 14 and the water storage tank 4 are connected through a water delivery pipeline. The water in the water delivery pipeline is pressurized by the water mist spraying pump 14, and then sprayed to the corresponding position by means of each of the water mist spraying nozzles 15. The water mist sprayed by the cleaning brush device 2 can prevent dust from being generated when cleaning garbage, and is sprayed in the inner absorption pipe section 9 to reduce dust in the garbage collection box 5, and increase the weight of the garbage so that it can fall freely after being output from the inner absorption pipe section 9, and minimize the floating of the garbage to prevent the garbage filter plate 11 from being blocked. The water mist sprayed in the air outlet hose 13 can prevent the high-pressure airflow discharged from the air outlet hose 13 from carrying dust or blowing onto the road surface to form dust, thereby minimizing the pollution of the surrounding air during the operation of the road sweeper.

[0027] Combination Figure 2 As shown, the wind direction adjustment device includes wind direction adjustment plates 16 hingedly installed on both sides of the air outlet hose 13, and telescopic adjustment rods 17 are connected to each wind direction adjustment plate 16. The two ends of the telescopic adjustment rods 17 are rotatably installed. Each telescopic adjustment rod 17 is set as an electric telescopic rod and the control end is set on the operation control panel in the cab. By adjusting the length of the two telescopic adjustment rods 17, the distance between the two wind direction adjustment plates 16 and the direction can be changed, thereby changing the size and direction of the air outlet of the air outlet hose 13. The air outlet hose 13 is relatively soft and can be deformed by the extrusion of the two wind direction adjustment plates 16 to achieve the control of the air outlet direction and intensity.

[0028] This embodiment has a garbage cleaning function, while also taking into account the humidification and dust reduction functions of the road surface. In addition, the amount of ground humidification and the degree of ground water mist penetration can be adjusted through the wind direction adjustment plate 16 according to different environmental and working conditions. The operation and maintenance costs of the vehicle are low, the operation is simple, and the use is flexible.
