Description

Technical Field

[0001] This invention relates to the field of shredder equipment, and more specifically to a durable dual-shaft shredder. Background Technology

[0002] Material recycling is the process of collecting and reusing waste materials generated during human activities. When waste materials are large in size, they are not easy to recycle. They usually need to be shredded or crushed into smaller pieces to facilitate recycling. Shredders are commonly used in the material recycling process. Large waste materials are fed into the shredder, which then shreds them to obtain materials of the appropriate size. However, during the shredding process, the blades wear down and become smaller. Once worn down, the blades no longer meet the requirements and need to be replaced, resulting in low blade utilization. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the present invention aims to provide a durable twin-shaft shredder in which the worn blades do not need to be discarded, but can be used again by installing the worn blades in the appropriate position.

[0004] This invention is achieved using the following technical solution:

[0005] A durable dual-shaft shredder includes a shredding roller, which comprises a rotating shaft and a plurality of blades. The blades are mounted on the rotating shaft and are detachably mounted to the rotating shaft. The size of the blades gradually decreases from the middle of the rotating shaft to both sides of the rotating shaft.

[0006] Preferably, the assembly includes a housing and several fixed blades. The fixed blades are mounted on the housing and are detachably mounted from the housing. The size of the fixed blades gradually decreases from the fixed blade located in the middle to the fixed blades located on both sides.

[0007] Preferably, the shredding roller shaft is provided with a plurality of annular cutter holders, and the blades are disposed on the annular cutter holders. The annular cutter holders are distributed at intervals on the rotating shaft, and the intervals between the annular cutter holders gradually decrease from the middle to the sides, with the fixed blades extending into the corresponding intervals.

[0008] Preferably, there are two shredding rollers, namely a first shredding roller and a second shredding roller. The blades of the first shredding roller extend into the gap of the annular cutter holder of the second shredding roller, and the blades of the second shredding roller extend into the gap of the annular cutter holder of the first shredding roller.

[0009] Preferably, the housing is provided with a feed inlet, the shredding roller shaft is located inside the housing, and the feed inlet is located directly above the first shredding roller shaft and the second shredding roller shaft.

[0010] Preferably, the housing is provided with a discharge port, the shredding roller shaft is located inside the housing, and the discharge port is located directly below the first shredding roller shaft and the second shredding roller shaft.

[0011] Preferably, the first shredding roller and the second shredding roller are located at the same height.

[0012] Preferably, a plurality of blade holders are provided on the inner wall of the housing, and fixed blade mounting positions are provided above and below the blade holders. The fixed blades are mounted on the fixed blade mounting positions and are inclined, with the blades of the fixed blades facing the shredding roller shaft.

[0013] Preferably, the cutter holders are distributed on the side of the first shredding roller and the side of the second shredding roller.

[0014] Preferably, each annular tool holder is provided with several blade mounting positions, and the blades are mounted on the blade mounting positions, which are arranged in an array around the central axis of the annular tool holder.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The durable dual-shaft shredder of the present invention sets the blades to different sizes. The blades located in the middle of the shaft are larger, and the size of the blades gradually decreases from the middle of the shaft to both sides. Since the blades in the middle of the shaft are the main ones tearing materials during the shredding process, the blades in the middle of the shaft wear out faster. After the blades are worn, they become smaller. The smaller blades can be removed and installed in a shaft position that is suitable for the size of the blade, so that the worn and smaller blades can continue to be used, thus improving the durability of the blades.

[0020] The following is combined Figure 1-3 The technical solution provided by the invention will be described in more detail.

[0021] like Figure 1-3 As shown, this embodiment of the invention provides a durable dual-shaft shredder, including a shredding roller 1. The shredding roller 1 includes a rotating shaft 2 and a plurality of blades. The blades are mounted on the rotating shaft 2 and are detachably connected to the rotating shaft 2. The size of the blades gradually decreases from the middle of the rotating shaft 2 to both sides. By setting the blades to different sizes, the blades located in the middle of the rotating shaft 2 are larger, and the size of the blades gradually decreases from the middle of the rotating shaft 2 to both sides. Since the blades in the middle of the rotating shaft 2 are mainly responsible for shredding materials during the process, they wear out faster. After the blades wear down, they become smaller. The smaller blades can be detached and installed in a rotating shaft 2 position that is suitable for the size of the blade, so that the worn and smaller blades can continue to be used, thus improving the durability of the blades.

[0022] The durable dual-shaft shredder includes a housing 3 and several fixed blades. The fixed blades are mounted on the housing 3 and are detachable from it. The size of the fixed blades gradually decreases from the central blade to the blades on the sides. The fixed blades, driven by the rotating shaft 2, enhance the shredding effect of the material. By setting the fixed blades to different sizes, with the central blade being larger and gradually decreasing in size towards the sides, the material is primarily shredded in the center. Therefore, the central blade wears out faster than the side blades. As the blades wear down, they become smaller and can be removed and reinstalled in positions suitable for their size, allowing them to continue to be used and improving their durability.

[0023] The shredding roller 1 is equipped with several annular cutter holders 4, with blades mounted on them. The annular cutter holders 4 are spaced apart on the rotating shaft 2, with the spacing gradually decreasing from the center to the sides. Fixed blades extend into the corresponding intervals. This structure, through the coordinated arrangement of the blades and fixed blades, improves the shredding effect of the equipment on materials.

[0024] Two shredding rollers 1 are provided: a first shredding roller 5 and a second shredding roller 6. The blades of the first shredding roller 5 extend into the gaps of the annular cutter holders 4 of the second shredding roller 6, and the blades of the second shredding roller 6 extend into the gaps of the annular cutter holders 4 of the first shredding roller 5. With the above structure, the cooperation between the first shredding roller 5 and the second shredding roller 6 improves the shredding effect of the equipment on materials.

[0025] The housing 3 is equipped with a feed inlet 7, and the shredding roller 1 is located inside the housing 3. The feed inlet 7 is located directly above the space between the first shredding roller 5 and the second shredding roller 6. By positioning the feed inlet 7 directly above the space between the first shredding roller 5 and the second shredding roller 6, most of the material entering through the feed inlet 7 can reach the shredding position between the first shredding roller 5 and the second shredding roller 6, thereby improving the shredding effect of the equipment on the material.

[0026] The casing 3 is equipped with a discharge port 8. The shredding roller 1 is located inside the casing 3, and the discharge port 8 is located directly below the first shredding roller 5 and the second shredding roller 6. Since most of the shredded material falls between the first shredding roller 5 and the second shredding roller 6, after the tire is shredded by the first shredding roller 5 and the second shredding roller 6, the tire can fall from between the first shredding roller 5 and the second shredding roller 6 to the discharge port 8. This makes it easier for the shredded material to be discharged from the discharge port 8, speeds up the discharge time, and prevents blockages.

[0027] The first shredding roller 5 and the second shredding roller 6 are located at the same height. The above structure is more conducive to shredding materials and facilitates the falling and discharge of the shredded materials.

[0028] Several blade holders 9 are arranged on the inner wall of the casing 3. Fixed blade mounting positions 10 are provided above and below each blade holder 9. The fixed blades are mounted on the fixed blade mounting positions 10 at an angle, with their blade edges facing the shredding roller shaft 1. This structure improves the shredding effect of the fixed blades on the material.

[0029] The blade holders 9 are distributed on the sides of the first shredding roller 5 and the second shredding roller 6. This structure improves the shredding effect of the fixed blades on the material.

[0030] Each annular cutter holder 4 has several blade mounting positions 11, on which blades are mounted. The blade mounting positions 11 are arranged in an array around the central axis of the annular cutter holder 4. This structure makes the blade distribution more uniform, resulting in better material shredding performance.

[0031] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
