Description

Technical Field

[0001] This utility model belongs to the technical field of paving equipment, and in particular relates to a polyurethane plastic track base paving equipment. Background Technology

[0002] Polyurethane running track base coat is a key material for running track construction. It has advantages such as high strength, high elasticity and excellent durability. It can be fully mixed with fillers such as rubber granules to build an extremely strong and durable running track base. Existing polyurethane running track base coat paving equipment often faces the problem of base coat adhesion during operation. Therefore, it is usually equipped with a heating device to heat the base coat to reduce its stickiness and facilitate construction operations.

[0003] However, many existing paving devices lack efficient and reasonable mixing equipment, making it difficult to achieve sufficient and uniform mixing of the primer during the heating process. This results in some primer being overheated, leading to aging and performance degradation, while other primers are underheated, remaining highly viscous and difficult to pave smoothly. This not only seriously affects the paving quality of the primer, resulting in poor flatness and uniformity of the runway base layer, but also greatly reduces construction efficiency and increases construction costs. Utility Model Content

[0004] The purpose of this invention is to provide a polyurethane plastic track base paving device. It includes a mixing section. Specifically, when the base adhesive in the storage tank is heated, a motor drives a rotating shaft. As the shaft rotates, a sleeve drives a mixing rod and a mixing blade to rotate and mix the base adhesive. Simultaneously, a guide groove on the outer wall of sleeve one engages with a guide rod on the inner wall of sleeve two, causing the mixing rod and blade to move axially up and down during rotation, thereby enhancing the mixing effect. This combination ensures the base adhesive in the storage tank is evenly mixed. Furthermore, the electric heating plate ensures more even heating of the base adhesive, effectively reducing its stickiness and providing better conditions for subsequent conveying and paving. This invention solves the problem that many existing paving devices lack efficient and reasonable mixing mechanisms.

The threaded rod drives the internal threaded block and the moving plate to slide along the U-shaped seat. When the moving plate moves, it drives the guide slide rod to slide in the guide slide groove through the guide slide groove. In turn, the guide slide rod drives the fixed block to slide on the slide rod, thereby flexibly adjusting the distance between the fixed blocks and realizing precise adjustment of the discharge pipe spacing. This allows the device to adapt to playgrounds of different widths, meet diverse paving needs, and improve the versatility and practicality of the device.

[0070] A specific application of this embodiment is: screw pump 321: screw pump 321 is a positive displacement rotary pump, mainly composed of screw, bushing and other components. It can be used to transport various media with high viscosity and containing solid particles. Its working principle is: when the driving screw rotates, it drives the driven screw that meshes with it to rotate together. A sealed cavity is formed between the screw and the bushing. As the screw rotates, the sealed cavity moves axially from the suction end to the discharge end. The medium is continuously transported from the suction end to the discharge end in the sealed cavity.

[0071] When using this device, the base adhesive material to be laid is first stored in the storage box 11 through the feeding port 231. At this time, the valve 233 is in the closed state. Then, the electric heating plate 112 in the heating box 111 outside the storage box 11 is energized to heat the base adhesive in the storage box 11, reducing the adhesive viscosity. At the same time, the motor 212 is started, and the motor 212 drives the rotating shaft 213 to rotate. The rotating shaft 213 drives the stirring rod 215 and stirring blade 216 to rotate through the sleeve 1 214, stirring the base adhesive. During the stirring process, the guide groove 222 on the outer wall of the sleeve 1 214 cooperates with the guide rod 223 on the inner wall of the sleeve 2 221, so that the sleeve 1 214 drives the stirring rod 215 and stirring blade 216 to move up and down along the axis while rotating, enhancing the stirring effect and making the base adhesive heated more evenly. Then, the valve 233 is opened, and the base adhesive can be discharged through the discharge pipe 232.

[0072] Start the screw pump 321. The mixed primer enters the screw pump 321 from the discharge pipe 232 through the connecting pipe 322. The screw pump 321 delivers the primer to the storage pipe 323 through the connecting pipe 324. When spreading the primer, if it is necessary to adjust the spacing between the outlets on multiple discharge pipes 325, the motor 312 can be started. The motor 312 drives the threaded rod 313 to rotate. The threaded rod 313 drives the internal threaded block 314 and the moving plate 315 to slide along the U-shaped seat 311. At the same time, the guide slide rod 319 on the fixed block 318 slides in the guide slide groove 316 of the moving plate 315, thereby adjusting the distance between the fixed blocks 318 and realizing the adjustment of the spacing of the discharge pipes 325. After adjustment... After completion, the primer in the storage pipe 323 is discharged to the ground through the hose 326 and the discharge pipe 325. Then, the scraping assembly 33 is activated, and the output shaft of the electric push rod 332 drives the mounting plate 333 and the scraper 334 to move up and down. The scraper 334 flattens the primer laid on the ground, and the two guide rods 335 ensure the stability of the movement of the mounting plate 333. Finally, the primer laying operation is completed. At the same time, since the scraper 334 is connected to the mounting plate 333 by bolts, when it is necessary to adjust the spacing between the discharge ports on the discharge pipe 325 to adapt to different widths of playground ground, the scraper 334 can be removed by bolts and replaced with a new scraper 334 that matches the width of the ground.
