Technical Field

[0001] The invention belongs to the field of plastic runways, in particular to a plastic runway material and a mixing device thereof. Background Art

[0002] The plastic track has the characteristics of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties, which is conducive to the athletes' speed and technology, effectively improving sports performance and reducing the rate of falls. The plastic track is made of polyurethane rubber and other materials, has a certain elasticity and color, has a certain UV resistance and aging resistance, and is internationally recognized as an outdoor sports field floor material.

[0003] Features of the all-plastic plastic track: The main material is two-component polyurethane, the base layer is natural rubber and artificial rubber, mixed with mineral fillers, stabilizers and colorants, and hardened at a high temperature of 280-300℃ and vulcanized to form an integrated whole. Combining sports science and material science, it can fully meet and reflect the professional requirements of athletes and participants for the track.

[0004] Traditional plastic track materials require that the prefabricated raw materials be placed in a simple mixing drum for on-site mixing. After mixing, the finished product is sprayed on the base using spraying equipment. After solidification, a plastic surface layer is formed. Due to the presence of plastic particles in the material, if it is prepared and transported, it will cause problems of particle precipitation and premature solidification. However, on-site mixing cannot use larger equipment, and it is necessary to wait until each mixing is completed before using the material, which causes the entire process to take a lot of time.

[0005] To this end, the present invention provides a plastic track material and a mixing device thereof. Summary of the invention

By adjusting the transmission speed of the raw materials in different raw material boxes, the amount of each raw material can be controlled, and finally the raw materials in the required proportion are sent to the mixing tank for stirring and mixing. After that, as the raw materials are continuously fed in, the mixed finished product will continue to push upward, and then fall into the finished product tank through the transfer pipe. When half a tank is accumulated in the finished product tank, the discharge pump can be started to continuously discharge the finished product through the discharge pipe, and the runway can be continuously laid.

After pulling up, rotate the inner rod. The inner rod is connected to the telescopic cylinder through a thread so that the inner rod can extend freely. Then put the mixing tank and the finished product tank back to their original positions, add clean water to the raw material box, and use the absorption tube to suck the clean water into it. The rotation of the stirring plate can allow the clean water to contact the inner wall at the bottom and clean it. At the same time, move the magnetic ring outside. The magnetic ring and the end of the inner rod are adsorbed so that the end of the inner rod always fits the inner wall. As the magnetic ring moves up and down, the elastic friction pad can clean the residue on the inner wall during the rotation process.
