Description

Technical Field

[0001] The utility model belongs to the field of spraying of plastic runways, in particular to a spraying device for a plastic runway of a stadium. Background Art

[0002] The plastic track is also called the all-weather track for athletics. It is composed of polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber particles or PU particles, pigments, additives, and fillers. The plastic track has the characteristics of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties. It is conducive to the athletes' speed and technology, effectively improving sports performance and reducing the rate of falls. The material box and the nozzle of the existing plastic track spraying device are connected by a long hose. When spraying, the staff does not need to keep pushing the material box to move, but directly hold the nozzle to spray the plastic track. However, due to the long hose, the hose is scattered on the ground during the spraying process, causing the outer periphery of the hose to be covered with dust or undried sprayed material, resulting in uneven material spraying, affecting the spraying effect. Therefore, we designed a stadium plastic track spraying equipment. Utility Model Content
