[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0022] Example 1

[0023] like Figures 1-3 As shown, a shredding device for waste tire processing includes a workbench 1 and support legs 2 located below the workbench 1. A shredding chamber 3 communicating with the workbench 1 is provided on the workbench 1, and two shredding rollers (not shown) are provided inside the shredding chamber 3. A feed inlet 4 is provided above the shredding chamber. A drive device for driving the two shredding rollers to rotate relative to each other is also provided on the workbench 1. It should be noted that the shredding rollers and the drive device for driving the two shredding rollers to rotate relative to each other are conventional devices in the art and will not be described in detail here. Two limiting plates 5 are correspondingly provided on the feed inlet 4, forming a limiting cavity between the two limiting plates 5 for allowing the waste tires to fall longitudinally into the space between the two shredding rollers. Below the shredding chamber 3, a first receiving net 6 and a second receiving net 7 are provided, detachably connected to the support legs 2. The first receiving net 6 is located above the second receiving net 7, and the mesh size of the first receiving net 6 and the second receiving net 7 are the same. By setting two limiting plates 5 on the feed inlet 4, the waste tires enter the crushing chamber 3 through the limiting cavity formed by the two limiting plates 5, so that the waste tires fall between the two crushing rollers in a vertical or nearly vertical state for shredding. This solves the problem in the prior art that the tires may lie horizontally above the crushing rollers and are not easy to be pulled in for shredding, thus improving the shredding efficiency.

[0024] Each leg 2 is equipped with a first support plate 12 for supporting the first receiving net 6 and a second support plate 13 for supporting the second receiving net 7. The structure is simple and allows the first receiving net 6 and the second receiving net 7 to be easily separated from the first support plate 12 and the second support plate 13.

[0025] The method of use in this embodiment is as follows: the waste tire to be shredded is put between the two limiting plates 5. The waste tire enters the crushing chamber 3 through the limiting cavity formed by the two limiting plates 5, so that the waste tire falls between the two crushing rollers in a vertical or nearly vertical state for shredding. Since the crushing chamber 3 is connected to the workbench 1, the shredded waste tire fragments will fall onto the first receiving net 6. Fragments smaller than the mesh size of the first receiving net 6 will continue to fall onto the second receiving net 7. Since the mesh size of the second receiving net 7 is the same as that of the first receiving net 6, the fragments falling from the first receiving net 6 will continue to fall through the mesh of the second receiving net 7. The workers can then collect the fragments falling from the mesh of the second receiving net 7. When a large number of fragments fail to pass through the mesh of the first receiving mesh 6, the worker removes the first receiving mesh 6 from the first support plate 12 and pours the fragments from the first receiving mesh 6 into the feed inlet 4. Due to the presence of the second receiving mesh 7, the machine does not need to be stopped even if the worker removes the first receiving mesh 6, and the shredding efficiency will not be affected. Similarly, when the second receiving mesh 7 is removed and fragments are poured into the feed inlet 4, the machine does not need to be stopped due to the presence of the first receiving mesh 6, and the shredding efficiency will not be affected. This ensures that qualified fragments are recycled while unqualified fragments continue to be shredded, thus guaranteeing the shredding effect.

[0026] Example 2

[0027] The similarities between this embodiment and Embodiment 1 will not be repeated here. The differences are as follows: Figures 4-5 As shown, due to the different tire widths, to accommodate waste tires of various widths, the two limiting plates 5 are slidably connected to the top of the feed inlet 4. An adjusting assembly for adjusting the distance between the two limiting plates 5 is provided on the feed inlet 4. The adjusting assembly includes two corresponding fixing plates 8 on the feed inlet 4, each with a threaded hole. An adjusting screw 9 is installed in each of the threaded holes. Bearings 10 are installed on both limiting plates 5, and the two adjusting screws 9 are fixedly connected to the inner rings of the corresponding bearings 10. The adjusting assembly increases the distance between the two limiting plates 5, thus accommodating waste tires of various widths and improving practicality.

[0028] To improve the ease of rotation of the two adjusting screws 9, a handwheel 11 is provided on each of the two adjusting screws 9. To facilitate the transportation of shredded waste tire fragments to the next process position, a transport plate 15 with rollers at the bottom is provided below the second receiving net 7.

[0029] Embodiment 3

[0030] The embodiment is same as embodiment 1, and the difference is that, as shown in the figure, the first longitudinal plate 14 for preventing the first receiving net 6 from moving is arranged on each first bearing plate 12, and the second longitudinal plate for preventing the second receiving net 7 from moving is arranged on each second bearing plate 12. By arranging the first longitudinal plate 14 and the second longitudinal plate, the first receiving net 6 and the second receiving net 7 can be limited, and the vibration of the workbench 1 and the supporting leg 2 caused by the broken waste tire can be prevented, so that the first receiving net 6 and the second receiving net 7 do not fall from the second bearing plate 12 and the second bearing plate 13.
