The dust suppression device also includes a protective plate fixedly connected to the fixing frame and positioned directly in front of the nozzle along the sweeper's travel direction.

[0004] The existing technology has the following technical defects:

[0005] However, the dust suppression structure in the above document wets the road surface in advance. On the one hand, this can easily leave marks on the road surface during subsequent sweeping, affecting the cleaning effect. On the other hand, if there are many impurities such as leaves on the road surface, the water sprayed by the dust suppression structure will be blocked by the leaves and other impurities, and only a small part will flow to the ground. As a result, the soil on the ground will still generate dust during subsequent sweeping, and the dust suppression effect will be poor. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a vehicle-mounted dust suppression device.

[0007] The vehicle-mounted dust suppression device of this utility model includes a mounting frame, a drive motor, a sweeping brush, and a water supply pipe.

[0021] Example 1

[0022] like Figures 1-2As shown, a vehicle-mounted dust suppression device includes a mounting frame 1, a drive motor 2, a sweeping brush 3, and a water pipe 4. The drive motor 2 is mounted on the side wall of the mounting frame 1 and is electrically connected to the power supply of an external sweeper. The sweeping brush 3 is mounted on the output end of the drive motor 2. One end of a connecting rod 5 is mounted on the side wall of the mounting frame 1, and the other end of the connecting rod 5 is mounted on the water pipe 4, which is connected to the water supply equipment on the external sweeper. A fan-shaped nozzle 6 is inserted and installed at the lower end of the water pipe 4. The mounting frame 1 serves as the basic support structure for the entire device, providing a stable mounting position for components such as the drive motor 2 and the sweeping brush 3. The drive motor 2 obtains power by connecting to the power supply of the sweeper and can drive the sweeping brush. The high-speed rotating brush 3 sweeps and concentrates dust and debris from the ground. The water pipe 4 is connected to a water supply system, delivering water to the fan-shaped nozzles 6. These nozzles spray water in a fan shape over a large area, rinsing the swept floor and simultaneously providing initial dust suppression for the dust raised by the brush 3, effectively reducing dust dispersion and improving cleaning efficiency. A surrounding dust suppression mechanism 7 is installed at the end of the water pipe 4. This mechanism includes a connecting pipe 71 and an atomizing nozzle 72. The connecting pipe 71 is installed on the side wall of the water pipe 4 and communicates with its inner cavity. The connecting pipe 71 is U-shaped and surrounds the outside of the brush 3. Atomizing nozzle 72 is installed at the lower end; a cleaning mechanism 8 is provided on the outside of the adapter pipe 71, which can clean the atomizing nozzle 72; the adapter pipe 71 is connected to the water supply pipe 4, which can introduce water from the water supply pipe 4. The U-shaped structure allows it to surround the outside of the sweeping brush 3, covering the working area of ​​the sweeping brush 3 in all directions; the atomizing nozzle 72 atomizes the introduced water and sprays it out, forming a fine water mist, which further adsorbs and settles the dust generated by the sweeping brush 3 during operation. Compared with the large-area spray of the fan-shaped nozzle 6, the dust suppression effect of the atomizing nozzle 72 is more refined, which can effectively suppress the flying of fine dust particles, further improve dust suppression efficiency, and reduce environmental pollution; because the atomizing nozzle 72 is used for a long time... During the process, the atomizing nozzle 72 may be clogged by impurities and dust in the water, resulting in poor atomization effect and affecting dust suppression performance. The cleaning mechanism 8 allows manual cleaning of the atomizing nozzle 72 to keep it unobstructed and ensure that the atomizing nozzle 72 is always in good working condition. This ensures that the surrounding dust suppression mechanism 7 can continuously and stably play an efficient dust suppression role, reducing the need for frequent maintenance due to nozzle clogging and improving the ease of use and reliability of the vehicle-mounted dust suppression device. Sealing gaskets are provided at the connection between the adapter pipe 71 and the water supply pipe 4, the connection between the atomizing nozzle 72 and the adapter pipe 71, the connection between the water supply pipe 4 and the fan-shaped nozzle 6, and the connection between the water supply pipe 4 and the external water supply equipment.

[0023] The cleaning mechanism 8 includes a collar 81, a clearance groove 82, bristles 83, and a lever 84. The collar 81 is sleeved on the outside of the adapter tube 71. The clearance groove 82 is formed on the inner side wall of the collar 81, and the bristles 83 are installed in the clearance groove 82. The atomizing nozzle 72 can slide into the clearance groove 82, and the bristles 83 can fit against the atomizing nozzle 72. The lever 84 is installed on the outer side wall of the collar 81. The collar 81 can slide flexibly on the outside of the adapter tube 71. When it is necessary to clean the atomizing nozzle 72, the lever 84 is moved to move the collar 81 to the outside of the atomizing nozzle 72, so that the atomizing nozzle 72 slides into the clearance groove 82. At this time, the bristles 83 installed in the clearance groove 82 will fit tightly against the surface of the atomizing nozzle 72. During the sliding process of the collar 81... In the process, the bristles 83 effectively remove impurities and dust adhering to the surface of the atomizing nozzle 72 and around the nozzle holes, enabling convenient cleaning of the atomizing nozzle 72. This structure is simple in design and easy to operate; cleaning can be completed without disassembling the atomizing nozzle 72, greatly improving maintenance efficiency and reducing maintenance costs. The outer wall of the collar 81 has a threaded hole 9, into which a positioning bolt 10 is screwed. The positioning bolt 10 fits snugly against the outer wall of the adapter pipe 71. The positioning bolt 10 serves to fix the position of the collar 81. After cleaning the atomizing nozzle 72, tightening the positioning bolt 10 ensures a tight fit against the outer wall of the adapter pipe 71, firmly fixing the collar 81 in its current position and preventing it from slipping during vehicle dust suppression. During operation, the device may slide randomly due to vibration or other factors, ensuring that the atomizing nozzle 72 is not obstructed and guaranteeing the normal operation of the surrounding dust suppression mechanism 7. Simultaneously, when further cleaning is required, the positioning bolt 10 can be loosened, allowing for easy sliding of the collar 81 and flexible operation of the cleaning mechanism 8. The adapter pipe 71 includes a main pipe body 711, a secondary pipe body 712, a piston ring 713, a locking bolt 714, and a hole 715. One end of the main pipe body 711 is connected to the water supply pipe 4, and the secondary pipe body 712 is inserted and installed at the other end of the main pipe body 711. A piston ring 713 is installed on the outer side of the inner end of the secondary pipe body 712, and the piston ring 713 fits against the inner wall of the main pipe body 711. The main pipe body 711 is close to... A locking bolt 714 is screwed into one end of the secondary pipe body 712. The locking bolt 714 can fit against the side wall of the secondary pipe body 712. Holes 715 are opened on the lower walls of both the main pipe body 711 and the secondary pipe body 712. The atomizing nozzle 72 is inserted into the hole 715. The main pipe body 711 is connected to the water supply pipe 4 to introduce water. The secondary pipe body 712 is inserted into the main pipe body 711 and fits against the inner wall of the main pipe body 711 through the piston ring 713 to ensure the sealing of the connection and prevent water leakage. By adjusting the depth of the secondary pipe body 712 inserted into the main pipe body 711, the overall length of the transfer pipe 71 can be changed, thereby adjusting the range around the outside of the sweeping brush 3 to adapt to different sizes of sweeping brush 3 or different sweeping operation needs.After adjusting to the appropriate length, tighten the locking bolt 714 to make it fit against the side wall of the secondary pipe body 712, which can firmly fix the secondary pipe body 712 in the current position and ensure the structural stability of the transfer pipe 71. Cleaning mechanisms are provided on the outer sides of both the main pipe body 711 and the secondary pipe body 712. Since both the main pipe body 711 and the secondary pipe body 712 are equipped with atomizing nozzles 72, the cleaning mechanisms 8 on both sides can thoroughly clean all the atomizing nozzles 72, ensuring that all the atomizing nozzles 72 of the entire surrounding dust suppression mechanism 7 maintain good atomization effect, further improving vehicle performance. The dust suppression performance and stability of the vehicle-mounted dust suppression device are improved, reducing uneven dust suppression caused by partial nozzle blockage, ensuring that the device maintains high dust suppression efficiency during cleaning operations. In some technical solutions, a dust cover 11 is fitted onto the upper outer side of the drive motor 2. In this solution, the dust cover 11 effectively prevents dust from entering the drive motor 2, preventing dust from causing wear on internal components and affecting heat dissipation, thus protecting the normal operation of the drive motor 2 and extending its service life.

[0024] Working principle: When the vehicle-mounted dust suppression device is working, the external sweeper's power supply powers the drive motor 2, which starts and drives the sweeping brush 3 to rotate at high speed. The sweeping brush 3 sweeps and collects dust and garbage from the ground. At the same time, the water supply equipment on the external sweeper delivers water to the water pipe 4. The water pipe 4 sprays water over a large area through the fan-shaped nozzles 6 at the lower end to wash the swept ground and also to initially suppress the dust raised by the sweeping brush 3. Water also enters the transfer pipe 71 surrounding the dust suppression mechanism 7 through the water pipe 4. The atomizing nozzles 72 on the transfer pipe 71 atomize the water and spray it out to form a fine water mist, which further absorbs the dust. It settles fine dust particles, achieving precise dust reduction. If the atomizing nozzle 72 becomes clogged during subsequent use, the atomizing nozzle 72 can be slid into the recessed groove 82 by moving the lever 84 of the cleaning mechanism 8. The brush bristles 83 can then be used to clean the nozzle. After cleaning, the atomizing nozzle 72 is exposed by sliding the collar 81, and the positioning bolt 10 is tightened to fix the collar 81. If the length of the adapter pipe 71 needs to be adjusted to suit different cleaning requirements, the locking bolt 714 can be loosened, and the depth of the secondary pipe body 712 inserted into the main pipe body 711 can be adjusted. After adjustment, the locking bolt 714 is tightened to fix the pipe.
