[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment: Please refer to Figures 1-4 , a spray dust reduction device for a road sweeper, including a vehicle body 11. A cavity 19 is opened inside the vehicle body 11, and waste bins 6 are opened inside both sides of the vehicle body 11. An air pump 9 is installed on one side inside the waste bin 6, and a feeding pipe 7 is installed at the output end of the air pump 9. An air extraction pipe 8 is installed at the input end of the air pump 9, and one end of the air extraction pipe 8 extends to the outside of the vehicle body 11 and is installed with an air extraction hood 4. A partition net 5 is installed at the bottom end of the air extraction hood 4. A rotating shaft 15 is installed inside the partition net 5 through a bearing, and the bottom end of the rotating shaft 15 extends below the partition net 5 and is installed with a scraper 14. The top end of the rotating shaft 15 extends into the air extraction hood 4, and fan blades 16 are installed on the outer wall of the rotating shaft 15 inside the air extraction hood 4;

[0020] A brush is installed at the top end of the scraper 14, and the top end of the scraper 14 is on the same horizontal plane as the bottom end of the partition net 5;

[0021] Specifically, as shown in Figure 1 , Figure 2 and Figure 3 , the air pump 9 also generates negative pressure through the air extraction pipe 8 and the air extraction hood 4, so that the dust near the tires is adsorbed, and is guided through the feeding pipe 7 into the waste bin 6 for storage, which can prevent the tires from raising dust. At the same time, the airflow can drive the fan blades 16 to rotate, so that the rotating shaft 15 drives the scraper 14 to rotate, and the scraper 14 is used to sweep off the larger sundries that cannot pass through and are adsorbed on the partition net 5, preventing them from affecting the dust adsorption of the device.

[0022] On both sides of the top of the vehicle body 11, fixed boxes 3 are installed. Inside one side of each fixed box 3, a cavity 19 is provided. On one side inside the cavity 19, a rotating rod 20 is installed through a rotating shaft. One end of the rotating rod 20 extends into the fixed box 3 and is installed with a driven bevel gear 21. On the outer wall of the rotating rod 20 inside the cavity 19, moving blocks 18 are installed. On one side of the top of each fixed box 3, a servo motor 17 is installed. The output end of the servo motor 17 extends into the fixed box 3 and is installed with a driving bevel gear 22. On the other side of the top of each fixed box 3, a mounting bracket 2 is installed. Inside the inner wall of the mounting bracket 2, a spray head 1 is installed through a hinge. On one side of each spray head 1, a transmission rod 10 is installed. One end of the transmission rod 10 is connected to the top of the moving block 18 through a hinge. On the top of each spray head 1, a water suction hose 13 is installed. One end of the water suction hose 13 extends into the water storage bin 12;

[0023] The driven bevel gear 21 and the driving bevel gear 22 are identical in shape and size, and the driven bevel gear 21 meshes with the driving bevel gear 22;

[0024] The outer wall of the rotating rod 20 is provided with an external thread, and the inner wall of the moving block 18 is provided with an internal thread matching it;

[0025] The connection mode between the moving block 18 and the cavity 19 is a sliding connection, and the moving range of the moving block 18 is less than the length inside the cavity 19;

[0026] The connection mode between the spray head 1 and the mounting bracket 2 is a rotating connection, and the rotating range of the spray head 1 is 150° - 210°;

[0027] Specifically, as Figure 1 and Figure 4 shown, by controlling the servo motor 17 to start, it can drive the rotating rod 20 to rotate with the cooperation of the driving bevel gear 22 and the driven bevel gear 21, causing the moving block 18 to move directionally inside the cavity 19. Thus, a force is applied to the spray head 1 through the transmission rod 10, causing the spray head 1 to rotate inside the mounting bracket 2, thereby changing the orientation of the spray head 1 and adjusting the spray angle, and can spray and reduce dust at a location with more dust.

[0028] Working principle: When using this device, first, the pump inside the water storage bin 12 of the device will send water into the inside of the pumping hose 13, and make it spray out from the nozzle 1. By controlling the start of the servo motor 17, it can drive the rotating rod 20 to rotate with the cooperation of the driving bevel gear 22 and the driven bevel gear 21, causing the moving block 18 to move directionally inside the cavity 19. Thus, a force is applied to the nozzle 1 through the transmission rod 10, causing the nozzle 1 to rotate inside the mounting frame 2, thereby changing the orientation of the nozzle 1 and adjusting the spray angle, and it can spray and suppress dust at a place with more dust.

[0029] At the same time, the air pump 9 also generates negative pressure through the air extraction pipe 8 and the air extraction hood 4, making it adsorb the dust near the tire and guide it through the feeding pipe 7 into the waste bin 6 for storage. It can prevent the tire from raising dust. At the same time, the air flow can drive the fan blade 16 to rotate, causing the rotating shaft 15 to drive the scraper 14 to rotate, and use the scraper 14 to sweep off the larger sundries that cannot pass through and are adsorbed on the partition net 5, preventing it from affecting the adsorption of dust by the device.

[0030] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claims involved.
