Description

Technical Field

[0001] This application relates to the field of road construction equipment, and more particularly to a negative pressure line removal suction device for traffic markings. Background Technology

[0002] In the field of traffic marking, shot grouting is an important method widely used in the production of various road markings. This technology primarily utilizes high-speed shot to impact the road surface, causing plastic deformation of the road material and thus forming clear and durable markings. However, during shot grouting operations, excess or scattered shot inevitably occurs. If this shot is not collected and disposed of promptly, it not only wastes materials but may also negatively impact the road environment and surrounding ecosystem.

[0003] Currently, while some recycling equipment and methods exist in the market to address the issue of recovering excess projectiles during road marking operations, they generally suffer from drawbacks such as low recycling efficiency, incomplete recovery, and complex operation. Some recycling equipment relies solely on simple mechanical structures for projectile collection, making it difficult to achieve efficient and comprehensive recovery of road surface projectiles; while some advanced recycling technologies are difficult to widely apply in the field of traffic marking due to factors such as high equipment costs and complex operation.

[0004] Furthermore, existing recycling technologies often lack effective filtration and cleaning mechanisms when processing recycled projectiles, resulting in a large amount of impurities mixed in with the recycled projectiles. This renders them unusable for subsequent marking operations, further increasing marking costs. Additionally, poorly designed or inconveniently operated recycling equipment can also affect the overall efficiency of the marking operation and reduce construction quality.

[0005] Therefore, developing an efficient, convenient, and environmentally friendly projectile recycling device has become an urgent problem to be solved in the field of traffic marking. This device should be able to efficiently recover excess projectiles from the road surface, while also having filtering and cleaning functions to ensure the reuse value of the recovered projectiles. Furthermore, the design of the device must also consider ease of operation, cost-effectiveness, and compatibility with environmental protection to meet the practical needs of the traffic marking field.

[0039] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application. It is understood that the accompanying drawings are provided for reference and illustration only, and are not intended to limit this application.

[0040] Specifically, such as Figure 1 As shown in the embodiment of this application, a negative pressure line removal suction device for traffic markings is provided. The device mainly includes a line removal vehicle 100, on which a shot recovery structure 300 is installed. The shot recovery structure 300 can effectively recover excess shot on the road surface under negative pressure.

[0041] Specifically:

[0042] The projectile recovery structure 300 mainly includes a negative pressure recovery nozzle 310, which is set on one side of the line removal vehicle 100. When the line removal vehicle 100 moves on the road surface, the negative pressure recovery nozzle 310 is set to the position of the road surface. After the line removal vehicle 100 finishes marking the line, the negative pressure recovery nozzle 310 recovers the projectiles on the road surface through the action of negative pressure.

[0043] After the negative pressure recovery nozzle 310 recovers the projectile through negative pressure, the projectile is moved through the negative pressure recovery pipe 320. The negative pressure recovery pipe 320 is connected to the negative pressure recovery nozzle 310. A primary negative pressure device 400 is installed on one side of the negative pressure recovery pipe 320. The primary negative pressure device 400 is installed at a position corresponding to the position of the negative pressure recovery nozzle 310. The primary negative pressure device 400 includes a drive pump 410, which is fixedly installed on the wire removal vehicle 100. The output end of the drive pump 410 is set at a position corresponding to the negative pressure recovery nozzle 310, so that the projectile moves from the negative pressure recovery nozzle 310 to the negative pressure recovery pipe 320 through the primary negative pressure device 400.

[0044] In this embodiment of the application, in the primary negative pressure device 400, the driving pump 410 is a fan structure. By rotating the fan, a small negative pressure range can be formed at the negative pressure recovery nozzle 310. The magnitude of the negative pressure can drive the projectile to be adsorbed from the ground to the negative pressure recovery nozzle 310.

[0045] In this embodiment, the negative pressure recovery pipe 320 is obliquely arranged on the wire removal vehicle 100, with an inclination angle of about 30 degrees. This angle setting ensures that the primary negative pressure device 400 can be set to correspond to the position of the negative pressure recovery nozzle 310, so as to facilitate the formation of negative pressure at the negative pressure recovery nozzle 310.

[0046] In this embodiment, since the negative pressure recovery nozzle 310 is vertically arranged, forming an angle with the negative pressure recovery pipe 320, a guide plate 420 is provided between the negative pressure recovery nozzle 310 and the negative pressure recovery pipe 320 to facilitate the projectile entering the negative pressure recovery pipe 320 through the negative pressure recovery nozzle 310. The guide plate 420 is part of the primary negative pressure device 400 and is set to correspond to the output position of the drive pump 410. The guide plate 420 is obliquely arranged between the negative pressure recovery nozzle 310 and the negative pressure recovery pipe 320 relative to the horizontal direction, so that the projectile adsorbed at the negative pressure recovery nozzle 310 is adsorbed onto the guide plate 420. Preferably, in this application, the guide plate 420 is set along the direction of the negative pressure recovery pipe 320.

[0047] A filter device 500 is also installed on the negative pressure recovery pipeline 320. The filter device 500 includes a filter frame 510 and a filter screen 520. The filter frame 510 is located in the middle of the negative pressure recovery pipeline 320 and is snapped onto the inner wall of the negative pressure recovery pipeline 320. The filter screen 520 is movably installed on the filter frame 510. The negative pressure recovery pipeline 320 can be isolated by the filter and the filter screen 520.

[0048] In this embodiment, the filter frame 510 is provided with a filter port 511, which is connected to the negative pressure recovery pipe 320. The filter screen 520 is set at the position corresponding to the filter port 511. The filter screen 520 can move linearly on the filter frame 510, and one side of the filter screen 520 abuts against the filter port 511, which can isolate the negative pressure recovery pipe 320. When it is necessary to filter the projectile in the negative pressure recovery pipe 320, the filter screen 520 is set at the position corresponding to the filter port 511, and the size of the filter holes on the filter screen 520 is smaller than the size of the projectile, thus isolating the negative pressure recovery pipe 320. When the projectile in the negative pressure recovery pipe 320 moves to the filter screen 520, the projectile is intercepted by the filter screen 520, thereby achieving the filtration of the projectile in the negative pressure recovery pipe 320.

[0049] In the above, a negative pressure device 330 is installed on the negative pressure recovery pipeline 320 at a position away from the negative pressure recovery nozzle 310. The negative pressure device 330 is installed on the wire removal vehicle 100. Activating the negative pressure device 330 can recover the projectile located in the negative pressure recovery pipeline 320.

[0050] Since a primary negative pressure device 400 is provided in this application, the negative pressure of the negative pressure device 330 is greater than that of the primary negative pressure device 400 in order to facilitate the movement of the projectile in the negative pressure recovery pipe 320.

[0051] In this embodiment, the power source for the linear movement of the filter screen 520 on the filter frame 510 is a drive device 530. The drive device 530 is located on one side of the negative pressure recovery pipe 320, and the output end of the drive device 530 is set to the position corresponding to the filter screen 520. The drive device 530 can drive the filter screen 520 to move linearly on the filter frame 510. The filter screen 520 is set to the position corresponding to the filter port 511, so as to isolate the negative pressure recovery pipe 320, or the filter screen 520 is set to a position away from the filter port 511, so that the negative pressure recovery pipe 320 is in a connected state.

[0052] In this embodiment, the driving device 530 is a telescopic rod 531. A telescopic groove 512 is provided on the filter frame 510 corresponding to the position of the telescopic rod 531. The telescopic rod 531 is located within the telescopic groove 512. A filter screen 520 is connected to the output end of the telescopic rod 531. The telescopic rod 531 drives the filter screen 520 to move linearly on the filter frame 510. When it is necessary to filter the projectiles in the negative pressure recovery pipe 320, the telescopic rod 531 extends, causing the filter screen 520 to move forward at the position corresponding to the filter port 511. The negative pressure recovery pipe 320 is isolated. When the projectile in the negative pressure recovery pipe 320 moves to the filter screen 520, the projectile is intercepted by the filter screen 520, thus filtering the projectile in the negative pressure recovery pipe 320. When it is necessary to discharge the projectile in the negative pressure recovery pipe 320, the telescopic rod 531 is shortened, which moves the filter screen 520 away from the filter port 511, so that the negative pressure recovery pipe 320 is in a connected state, and the projectile in the negative pressure recovery pipe 320 is discharged.

[0053] In this embodiment, the filter device 500 further includes a storage box 540, which is disposed on one side of the negative pressure recovery pipe 320. The negative pressure recovery pipe 320 has a storage opening corresponding to the storage box 540, and the storage opening connects the storage box 540 and the negative pressure recovery pipe 320. The storage box 540 can collect the pellets trapped on the filter screen 520, preventing the pellets from falling into the negative pressure recovery pipe 320 and causing blockage, thus affecting the negative pressure recovery efficiency of the negative pressure recovery pipe 320.

[0054] In this embodiment, the receiving port is positioned corresponding to the filter screen 520. When it is necessary to discharge the pellets in the negative pressure recovery pipe 320, the filter screen 520 is positioned away from the receiving port, so that the receiving port is in a connected state. The pellets in the negative pressure recovery pipe 320 enter the receiving box 540 through the receiving port, thereby realizing the discharge and collection of the pellets in the negative pressure recovery pipe 320.

[0055] In this embodiment, to facilitate the cleaning of the pellets on the filter screen 520 and prevent excessive pellets from being trapped on the filter screen 520, which could cause blockage and affect the negative pressure recovery efficiency of the negative pressure recovery pipeline 320, a scraper 550 is also provided on the filter device 500. The scraper 550 rotates on the storage box 540 via the rotation adjustment device 560. When the scraper 550 is in a certain position, the end of the scraper 550 away from the rotation adjustment device 560 abuts against the filter screen 520. The scraper 550 can scrape the filter screen 520 to remove the pellets trapped on the filter screen 520, thereby cleaning the filter screen 520.

[0056] As described above, when the scraper 550 scrapes the filter screen 520, it is necessary to adjust the size of the negative pressure device 330, reduce or even turn off the negative pressure device 330 to avoid the storage box 540 being affected by the negative pressure.

[0057] In this embodiment, the rotation adjustment device 560 is a motor. The output end of the motor is set at the position corresponding to the scraper 550. The motor can drive the scraper 550 to rotate on the storage box 540. When it is necessary to clean the filter screen 520, the motor is started, which drives the scraper 550 to rotate. The end of the scraper 550 away from the motor abuts against the filter screen 520. The scraper 550 can scrape the filter screen 520, scraping off the bullets trapped on the filter screen 520, so that the bullets fall into the storage box 540, thus cleaning the filter screen 520. After cleaning is completed, the motor is turned off, and the scraper 550 stops rotating.

[0058] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
