Description

Technical Field

[0001] This utility model relates to the technical field of road marking spraying devices, specifically a road marking paint uniformity adjustment device. Background Technology

[0002] Traffic markings are road markings that use lines, arrows, text, vertical markings, raised pavement markers, and delineators to convey traffic information such as guidance, restrictions, and warnings to road users. Their main function is to manage and guide traffic flow. They can be used in conjunction with traffic signs or function independently. However, existing road marking paint spraying devices still have certain shortcomings, such as:

[0003] The patent application CN201910064869.5, entitled "A Flexible Road Marking Device and Working Method for Construction," includes a vehicle body and a box body. A tube is installed on the left side of the bottom of the vehicle body. Baffle devices are movably sleeved on both the front and rear sides of the outer wall of the tube. A smoothing device is installed on the left side of the bottom side wall of the two sets of baffle devices. Piston blocks are movably inserted into both the front and rear sides of the inner cavity of the tube. This device cannot stir the paint in the mixing tank during use, which makes the paint prone to sedimentation after a long period of standing, affecting the spraying effect and failing to meet the usage requirements. In view of this, a road marking paint spraying uniformity adjustment device is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a marking paint spraying uniformity adjustment device to solve the problem mentioned in the background art that the existing marking paint spraying device cannot stir the paint in the mixing tank during use, which makes the paint prone to sedimentation after a long period of standing, thus affecting the spraying effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a trolley, a mixing tank, and an output pump. The lower ends of the mixing tank and the output pump are fixedly connected to the upper end of the trolley. A motor is fixedly connected to the center of the upper end of the trolley, and an output shaft is fixedly connected to the end of the motor shaft. The output shaft passes through the upper end of the mixing tank, and the lower end of the output shaft is connected to a bearing on the inner bottom surface of the mixing tank. A U-shaped scraper is fixedly connected to the output shaft. A rotating rod is connected to a bearing on the inner top surface of the right side of the mixing tank, and the rotating rod is symmetrically arranged about the output shaft.

[0006] The above technical solution is adopted to prevent the coating from settling or clumping during the stirring process.

[0007] As a preferred embodiment of this utility model, both the output shaft and the rotating rod are fixedly connected to transmission gears, and the output shaft and the rotating rod are driven by meshing transmission gears; the rotating rod is fixedly connected to a stirring rod.

[0008] The above technical solution facilitates the improvement of paint uniformity and ensures the quality of road marking spraying.

[0009] As a preferred embodiment of this utility model, a baffle is fixedly connected to the inner wall of the mixing tank, and both the output shaft and the rotating rod pass through the baffle; a leak-proof sealing gasket is provided at the connection between the output shaft and the rotating rod and the baffle.

[0010] The above technical solution facilitates the improvement of the device's practicality and environmental friendliness.

[0011] As a preferred embodiment of this utility model, a feed hopper is fixedly connected to the left end face of the mixing tank, and the feed hopper penetrates the left end face of the mixing tank; a solenoid valve is provided at the tail end inside the feed hopper.

[0012] By adopting the above technical solution, it is easier to control the amount of coating material fed, and the practicality and ease of operation of the device are further improved.

[0013] As a preferred embodiment of this utility model, an electric sprayer is fixedly connected to the lower end face of the trolley, and a pipe is fixedly connected between the mixing tank, the output pump and the electric sprayer; an electromagnetic control valve is fixedly connected inside the pipe.

[0014] The above technical solution facilitates the automatic delivery and spraying of paint, reduces the tediousness of manual operation, and improves work efficiency. At the same time, the design enables the paint to be delivered evenly and quickly to the electric sprayer, further ensuring the uniformity and quality of the marking spraying.

[0015] As a preferred embodiment of this utility model, a spring shock absorber is fixedly connected to the lower end face of the mixing tank, and the spring shock absorber is symmetrically arranged about the center of the mixing tank.

[0016] The above technical solution helps to reduce vibration and noise generated during the stirring process, and improves the stability and service life of the device.

[0017] As a preferred embodiment of this utility model, the lower end face of the spring shock absorber is fixedly connected to the base, and the lower end face of the base is fixedly connected to the upper end face of the trolley; a rain shield is fixedly connected to the upper end face of the mixing tank.

[0018] By adopting the above technical solution, the motor is prevented from being corroded by rainwater, thus extending the service life of the device; at the same time, the safety of the device during operation is improved.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the device not only realizes the stirring of the coating in the mixing tank through a single power source, but also scrapes the coating at the edge of the inner wall of the mixing tank, avoiding the residue of coating on the inner wall of the mixing tank, and further ensuring the uniformity and utilization rate of the coating.

[0020] 1. When in use, the operator starts the motor, which drives the output shaft to rotate. The output shaft drives the rotating rod to rotate through the transmission gear. The rotating rod drives the stirring rod on the rotating rod to evenly stir the paint in the mixing tank, so that the paint reaches a uniform state before spraying, avoiding uneven spraying caused by paint sedimentation or layering.

[0021] 2. By adjusting the motor speed, the stirring speed and intensity can be further controlled, thereby achieving fine adjustment of the coating uniformity;

[0022] 3. At the same time, the output shaft drives the U-shaped scraper to scrape off the paint at the inner edge of the mixing tank, effectively preventing the paint from adhering to the inner wall of the mixing tank and avoiding paint waste and uneven mixing. The U-shaped scraper can closely adhere to the inner wall of the mixing tank to ensure the scraping effect. In addition, the U-shaped scraper is made of wear-resistant material, which has a long service life, reduces the replacement frequency, and improves the overall economy of the device.

[0023] 4. Then start the output pump. The output pump delivers the evenly mixed paint to the electric sprayer through the pipeline (which is equipped with an electromagnetic control valve). The paint is then evenly sprayed onto the road surface through the spraying device.

[0024] 5. With the spring shock absorber, the vibration generated during the mixing process is effectively absorbed and buffered, which also protects the mixing components from damage caused by long-term vibration and extends the service life of the device. With the rain shield, the device can continue to work in rainy or other inclement weather conditions, preventing rainwater from directly wetting the motor, facilitating routine maintenance and upkeep by staff, and further improving the practicality and durability of the device.
