Description

Technical Field

[0001] The utility model relates to the technical field of crushing equipment, in particular to a crushing component and an environmentally friendly crusher. Background Art

[0002] An environmentally friendly pulverizer is a device used to process waste and recycle materials. The crushing component is a key component of the environmentally friendly pulverizer, which is responsible for crushing, decomposing or compressing the original material into the required size and shape. The environmentally friendly pulverizer minimizes the impact on the environment and increases the recycling rate.

[0003] In the prior art, conventional crushing assemblies generally use welding devices to directly weld and fix the crushing cutter heads to the outside of the rotating shaft to enhance stability during crushing. However, after long-term use, individual crushing cutter heads may be damaged. Since the crushing cutter heads are welded to the rotating shaft as one body, the entire crushing roller needs to be replaced when replacing the damaged cutter heads, which increases maintenance costs and reduces flexibility.

[0004] Therefore, a crushing assembly and an environmentally friendly pulverizer are needed to improve the problem that the existing crushing roller lacks flexibility and needs to be disassembled as a whole for replacement. Utility Model Content

[0007] Preferably, a plurality of mounting grooves are provided at the right end of the rotating shaft, and a baffle is sleeved on the right side of the rotating shaft.

[0008] A plurality of bolts 2 are arranged on the outer side of the baffle.

[0009] Preferably, the second bolt passes through the baffle and is threadedly connected to the inner wall of the mounting groove.

[0010] Preferably, a plurality of the crushing blade heads b are each provided with a plurality of protrusions on one side away from the crushing blade body, and the cross section of the protrusions is in a "V" shape, and the plurality of crushing blade heads b are centrally symmetrically arranged on the outer side of the crushing blade body.

[0011] Preferably, two crushing cutter heads b are installed on one side of the plurality of crushing cutter heads c away from the crushing cutter body, and two fixing blocks are symmetrically arranged on one side of the crushing cutter head b.

[0012] Preferably, a plug-in hole is opened in the middle of the crushing cutter body, and the inner wall of the plug-in hole is close to the outer side of the rotating shaft. A mounting hole is opened in the middle of the mounting block, and the inner wall of the mounting hole is close to the outer side of the rotating shaft.

[0026] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Embodiment 1

[0028] See also Figure 1-Figure 8 The utility model provides a technical solution: a crushing assembly, including a rotating shaft 1, four crushing cutter heads b15 and four crushing cutter heads c17, mounting blocks 2 are sleeved on the left and right sides of the rotating shaft 1, multiple bolts 6 are arranged on the outside of the mounting block 2, nuts 5 are threadedly connected on the sides close to the bolts 6 on the left and right sides, multiple crushing cutter bodies 3 are sleeved on the outside of the mounting block 2, a sleeve 4 is installed on the right side of the crushing cutter body 3, multiple crushing cutter heads a12 are installed on the outside of the crushing cutter body 3, and two bolts three 13 are inserted in the middle of the crushing cutter head a12.

[0029] First, the worker removes the four bolts 6 on the outside of the mounting block 2, and then takes down the two mounting blocks 2 along the outer wall of the rotating shaft 1 through the mounting holes 7. Subsequently, the entire rotating shaft 1 is taken out of the crusher and placed on the processing table. When the crushing cutter head a12 is damaged, the two bolts 13 in the middle of the crushing cutter head a12 are unscrewed with tools, and the crushing cutter head a12 can be replaced to improve the flexibility of replacing the crushing cutter head a12.

[0030] Embodiment 2

[0031] On the basis of Example 1, in order to facilitate workers to replace the crushing knife body 3 separately, a plurality of mounting grooves 10 are opened at the right end of the rotating shaft 1, a baffle plate 8 is sleeved on the right side of the rotating shaft 1, and a plurality of bolts 9 are arranged on the outside of the baffle plate 8. The bolts 9 penetrate the baffle plate 8 and are threadedly connected to the inner wall of the mounting groove 10.

[0032] When the crushing knife body 3 is damaged, at this time, unscrew the four bolts 29 on the right side of the shaft 1 and let it move to the right along the inner wall of the mounting groove 10. After the bolts 29 are removed, move the baffle 8 to the right to let it separate from the outside of the shaft 1. Then the worker checks the position where the crushing knife body 3 needs to be replaced, and then takes out the sleeve 4 to the right one by one while taking out the crushing knife body 3 to the right one by one, so as to facilitate the worker to replace the crushing knife body 3. After the replacement is completed, the worker resets the crushing knife body 3 and the sleeve 4 one by one, and fixes the baffle 8 to the right side of the shaft 1 with the bolts 29, and then installs the entire crushing assembly together with the crusher.

[0033] Embodiment 3

[0034] On the basis of the second embodiment, in order to facilitate users to replace the crushing cutter head a12 according to different usage requirements, multiple crushing cutter heads b15 are installed with multiple protrusions 14 on the side away from the crushing cutter body 3, and the cross-section of the protrusion 14 is "V"-shaped, and the multiple crushing cutter heads b15 are arranged symmetrically on the outside of the crushing cutter body 3, and multiple crushing cutter heads c17 are installed with two crushing cutter heads b15 on the side away from the crushing cutter body 3, and two fixing blocks 16 are symmetrically arranged on one side of the crushing cutter head b15.

[0035] A plurality of protrusions 14 are installed on one side of the crushing cutter head b15, so that when the crushing cutter head b15 is crushing, the material can enter the crushing area more easily and more fragments can be produced in the crushing process, thereby improving the crushing efficiency. Two fixed blocks 16 are installed on one side of the crushing cutter head c17, so that the fixed blocks 16 can crush the material more evenly during crushing, and the two fixed blocks 16 are symmetrically arranged, so that the crushing assembly can be reversed, thereby improving the adaptability of the crusher and improving the use effect of the crushing assembly.
