[0003] The construction materials of the plastic runway are composed of polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber particles or PU particles, pigments, additives, and fillers. The construction of the plastic runway has the characteristics of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties, which is conducive to the exertion of athletes' speed and skills, effectively improves sports performance, and reduces the injury rate. The plastic runway construction is composed of materials such as polyurethane rubber, has a certain elasticity and color, has a certain ability to resist ultraviolet rays and aging resistance, and is recognized as the best all-weather outdoor sports field floor material in the world. It is commonly used for playground runways.

[0004] When the existing raw material mixing equipment for plastic runway construction mixes the raw materials, it mixes the granular materials with the component glue and then conveys and lays them. Since the overall viscosity increases after the component glue and the granular materials are mixed, the subsequent transportation and laying difficulties are greatly increased, resulting in a significant reduction in the construction efficiency of the elastic runway.

The upper ends of the long-axis stirring screw and the short-axis stirring screw are fixed on both sides of the fixed bracket, and a small driving motor is connected to the tops of both. The middle of the fixed bracket is connected to an external stirring driving motor. Among them, an integrated component glue tank is arranged at the front end outside the mixing and stirring tank, and a gear pump is connected to the lower end of the component glue tank. A conveying spiral pipe is connected to the lower ends of the mixing and stirring tank and the component glue tank.

At the same time, a glue overflow pipe is connected to the front end of the conveying spiral pipe, and the glue overflow pipe is connected to the upper end of the component glue tank.

However, it should be understood that these descriptions are only exemplary and do not intend to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0019] Refer to Figures 1 - 3 As shown, the following technical solutions are adopted in this specific embodiment: It includes a mixing and stirring tank 1, a long-axis stirring screw rod 2, a short-axis stirring screw rod 3, a fixed bracket 4, a small driving motor 5, a stirring driving motor 6, a component glue tank 7, a gear pump 8, a conveying spiral pipe 9, and a glue overflow pipe 10; inside the mixing and stirring tank 1, there are a long-axis stirring screw rod 2 and a short-axis stirring screw rod 3. The upper ends of the long-axis stirring screw rod 2 and the short-axis stirring screw rod 3 are fixed on both sides of the fixed bracket 4, and a small driving motor 5 is connected to the tops of both; the middle of the fixed bracket 4 is connected to an external stirring driving motor 6. Among them, an integrated component glue tank 7 is arranged at the front end outside the mixing and stirring tank 1, and a gear pump 8 is connected to the lower end of the component glue tank 7; a conveying spiral pipe 9 is connected to the lower ends of the mixing and stirring tank 1 and the component glue tank 7. The conveying spiral pipe 9 connects the mixing and stirring tank 1 and the component glue tank 7 together for mixing elastic granular materials and glue. At the same time, the front end of the conveying spiral pipe 9 is connected to a glue overflow pipe 10, and the glue overflow pipe 10 is connected to the upper end of the component glue tank 7.

[0020] Among them, the tail of the conveying spiral pipe 9 is connected with a flat spreading flared opening 11 through a flange. The flat spreading flared opening 11 has a fan-shaped structure with a wide inlet and a narrow outlet; inside the flat spreading flared opening 11, there are multi-stage shunt baffles 14 with different lengths.

[0021] In addition, a rotary ball head 12 is connected to the lower end of the long-axis stirring screw rod 2. The rotary ball head 12 is clamped in the middle of the hollow support 13 at the bottom of the mixing and stirring tank 1, increasing the rotation stability of the long-axis stirring screw rod 2. The mixing and stirring tank 1, the component glue tank 7, and the conveying screw pipe 9 are integrally fixed inside the moving frame 6 to form an integral mobile structure.

[0022] The working principle of this specific embodiment is as follows: First, various pulverized rubber granular materials are added from one side at the upper end of the mixing and stirring tank 1, and the rubber granular materials are stirred under the spiral self-rotation of the long-axis stirring screw rod 2 and the short-axis stirring screw rod 3. At the same time, the long-axis stirring screw rod 2 and the short-axis stirring screw rod 3 perform a revolution driven by the fixed support 4 to further improve the mixing efficiency. The mixed granular materials enter the inside of the conveying screw pipe 9 from the bottom. During the conveying process, the gear pump 8 at the bottom of the component glue tank 7 conveys the component glue into the inside of the conveying screw pipe 9, enabling the component glue to penetrate into the rubber granular materials and further mixing during the rotation of the conveying screw pipe 9. Finally, the mixed rubber granular materials are laid flat on the construction ground through the extrusion and diversion of the flat spreading flared opening 11, greatly reducing the workload of manual spreading.
