[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0026] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0027] This utility model discloses a centralized processing and crushing device for waste tires, according to the attached... Figure 1-3 As shown, it includes:
[0028] The crushing unit 1 includes a crushing box 11, a crushing component 12, and a feed inlet 13. The feed inlet 13 is located on the top of the crushing box 11, and the crushing component 12 is located on the crushing box 11 and crushes the waste tires that enter the crushing box 11 through the feed inlet 13.
[0029] The blocking unit 2 includes multiple fixing bars 21, which are respectively fixedly installed at the four corners of the top of the feed inlet 13. Each fixing bar 21 is provided with a movable rod 22, and multiple blocking nets 23 are connected between the multiple movable rods 22. The multiple blocking nets 23 are used to block the waste tires that pop out during feeding and the tire fragments generated during the crushing process from splashing outward.
[0030] Multiple barrier nets 23 are connected by movable rods 22 and fixed bars 21 to form an adjustable protective barrier outside the loading position of the loader, effectively intercepting tires ejected during feeding and fragments flying from the broken parts. At the same time, the movable rods 22 can slide up and down along the fixed bars 21 and are fixed in position by threaded connection between the movable rods 22 and the collars 24, adapting to the feeding of tires and the on-site protection requirements under different conditions.
[0031] According to the appendix Figure 2 As shown, the crushing assembly 12 further includes a drive motor 121, two drive shafts 122 and two crushing rollers 123. The drive motor 121 is fixedly installed on the outside of the crushing box 11. The two drive shafts 122 are arranged through the crushing box 11, and the output end of the drive motor 121 is fixedly connected to one of the drive shafts 122. The two crushing rollers 123 are respectively fixedly sleeved on the outside of the two drive shafts 122.
[0032] A gearbox 124 is fixedly installed on the side of the crushing box 11 away from the drive motor 121. The ends of the two drive shafts 122 extend into the gearbox 124, and gears are sequentially meshed between the ends of the two drive shafts 122. The two drive shafts 122 can rotate relative to each other through multiple gears.
[0033] The drive motor 121 drives the two crushing rollers 123 to rotate relative to each other through the drive shaft 122. The gear set in the gearbox 124 is used to achieve synchronous reverse rotation, ensuring that the tires are fully sheared and squeezed, thus improving the crushing efficiency.
[0034] According to the appendix Figure 1-2 As shown, a discharge port 14 is further fixedly installed at the bottom of the crushing box 11.
[0035] The discharge port 14 is located at the bottom of the crushing box 11. With the squeezing action of the crushing roller 123, the crushed material falls naturally, reducing the cost of manual material discharge.
[0036] According to the appendix Figure 3-4 As shown, furthermore, each of the four corners of the barrier net 23 is fixedly connected to a connecting block 231, and the connecting block 231 is fixedly connected to the top or bottom of the movable rod 22.
[0037] The movable rod 22 is movably inserted into the fixed strip 21. The bottom of the fixed strip 21 is rotatably connected to a collar 24, and the collar 24 is sleeved on the outside of the movable rod 22.
[0038] The inner wall of the collar 24 is threaded, and the outer side of the movable rod 22 is threaded. The thread of the collar 24 is threadedly connected to the threaded groove on the outer side of the movable rod 22.
[0039] The operator uses a loader to feed waste tires into the crushing box 11 through the feed inlet 13. At this time, the barrier net 23 is adjusted above the feed inlet 13 by the movable rod 22 to form a protective barrier to prevent the tires from jumping out due to elastic rebound.
[0040] The drive motor 121 starts and drives the two crushing rollers 123 to rotate relative to each other through the drive shaft 122. The tire is crushed into small pieces under the shearing and squeezing action of the crushing rollers 123. The gear set in the gearbox 124 ensures that the two crushing rollers 123 always rotate in opposite directions to avoid material jamming.
[0041] During the crushing process, since the blocking net 23 is located inside and above the crushing box 11, it can intercept flying fragments such as steel wire and rubber particles; the collar 24 fastens the movable rod 22 with threads to prevent the blocking net 23 from shifting during vibration; the crushed material is discharged naturally from the discharge port 14, completing the processing.
