[0034] Working principle and process of high-strength wear-resistant racks with replaceable, modular teeth:
[0035] To facilitate rack maintenance, the rack is divided into a tooth section and a base. Positioning blocks 9 are installed on the left and right sides of the lower end face of the high-wear-resistant tooth section 1. The positioning blocks 9 are then aligned with the positioning groove 13 inside the upper end face of the high-strength base 16. The lower end face of the high-wear-resistant tooth section 1 is then fitted against the upper end face of the high-strength base 16, ensuring the positioning blocks 9 are fixed inside the positioning groove 13 for proper positioning and assembly. To prevent instability, threaded grooves 14 are provided on the front and rear sides of the high-strength base 16. A threaded rod 8 is rotatably installed inside the threaded grooves 14. Hollow threaded blocks 10, fixed on the left and right sides of the lower end face of the high-wear-resistant tooth section 1, are aligned with the threaded rod 8, allowing the threaded rod 8 to pass through the hollow threaded blocks 10 for further fixation. A rubber sealing frame 2 is fixed to the lower end of the outer ring of the high-wear-resistant tooth section 1. The inner side of the lower end face of the rubber sealing frame 2 is then fitted with the high-strength base 16. The outer side of the upper end face of the high-strength base 16 is fixed to enhance the overall sealing and prevent dust and liquid from seeping into the splice, which would cause wear and corrosion to the splice. To facilitate the splicing of the high-strength base 16, a dovetail guide rail 11 is fixedly installed on the lower end face of the high-strength base 16. A dovetail groove 4 is slidably installed on the outer side of the lower end of the dovetail guide rail 11 for a sliding connection.
