Description
Technical Field
[0001] This utility model relates to the field of crusher technology, specifically to a crusher crushing structure that is easy to maintain. Background Technology
[0002] A crusher is a device specifically designed to break large solid materials into smaller particles using mechanical force. It is widely used in mining, building materials production, metallurgy, chemical engineering, road construction, and other fields. The most important structure of a crusher is the crushing mechanism, which is used to crush the input material.
[0003] The existing crusher's crushing structure is poorly designed and overly complex. The crushing teeth or blocks are fixed to the drive shaft, preventing tool-free disassembly after damage. This makes maintenance extremely cumbersome, requiring complete replacement of the entire crushing structure, resulting in high maintenance costs. Furthermore, the crushing teeth or blocks are independent of each other, with adjacent teeth or blocks failing to interact during rotation, thus lacking self-cleaning capabilities. Manual cleaning becomes very inconvenient when there is a significant amount of debris adhering to the surface. Therefore, the inventor has improved the crusher's crushing structure. Utility Model Content

[0020] Please see Figure 1The present invention provides an embodiment of a crusher crushing structure that is easy to maintain. The crusher crushing structure includes a support component 1, a drive component 2, and a crushing component 3, wherein the drive component 2 is fixed to one side of the support component 1 and is connected to the crushing component 3.
[0021] Please see Figure 2 The support assembly 1 includes a crushing tank 11 and a hopper 12 fixed to the upper surface of the crushing tank 11. The crushing tank 11 is a hollow cavity structure with openings at both ends. The openings at both ends of the crushing tank 11 are located at its top and bottom. The hopper 12 communicates with the opening at the top of the crushing tank 11. The drive assembly 2 includes a motor 21, a first driving gear 22, and a first driven gear 23. The motor 21 is fixed to the crushing tank 11. The first driving gear 22 is located on one side of the first driven gear 23 and is fixedly connected to the output end of the motor 21. The first driving gear 22 and the first driven gear 23 are connected by a chain 24. A second driving gear 25 and a second driven gear 26 are provided at the end of the first driven gear 23 away from the first driving gear 22. The second driving gear 25 is connected to the first driven gear 23. Gear 23 is fixedly connected, and the second driving gear 25 meshes with the second driven gear 26. The crushing assembly 3 includes a first drive shaft 31 and a second drive shaft 32 arranged in parallel. The first drive shaft 31 passes through the first driven gear 23 and the second driving gear 25, and is coaxially connected to the first driven gear 23 and the second driving gear 25 respectively. The second drive shaft 32 passes through the second driven gear 26 and is coaxially connected to the second driven gear 26. In addition, the first drive shaft 31 and the second drive shaft 32 are respectively mounted on two sets of bearings 36. Both sets of bearings 36 are fixed on the crushing tank 11. In this embodiment, each set of bearings 36 is provided with two bearings, and the two bearings 36 are symmetrically mounted on the crushing tank 11. Therefore, the two ends of the first drive shaft 31 or the second drive shaft 32 can be supported to make it operate stably.
[0022] Please see Figure 3 Two sets of crushing discs 33 are provided on the first drive shaft 31 and the second drive shaft 32, that is, there are four sets of crushing discs 33 in total. All four sets of crushing discs 33 are located in the cavity of the crushing tank 11. Each set of crushing discs 33 has multiple discs. The two sets of crushing discs 33 on the second drive shaft 32 are distributed crosswise and at equal intervals on the second drive shaft 32. The two sets of crushing discs 33 have different orientations, so more complex crushing actions can be achieved during high-speed operation, resulting in better crushing effect. Similarly, the arrangement of the two sets of crushing discs 33 on the first drive shaft 31 is exactly the same as that of the two sets of crushing discs 33 on the second drive shaft 32. Multiple crushing blocks 34 are provided on the circumference of each set of crushing discs 33. Each crushing block 34 is detachably mounted with a positioning rod 35. The crushing block 34 is in contact with the surface of the crushing disc 33.
[0023] Please see Figure 4 The crushing disc 33 includes a support base 331, on which a placement groove 332 and a through hole 333 communicating with the placement groove 332 are provided. A receiving groove 334 is also formed inside the support base 331. A positioning rod 35 passes through the placement groove 332 from the outside to the inside and enters the through hole 333. An adapter hole 351 is provided at one end of the positioning rod 35 near the receiving groove 334. A spring 335 and an insert rod 336 are provided inside the receiving groove 334. The two ends of the spring 335 are connected to the inner wall of the receiving groove 334 and the insert rod 336, respectively. The insert rod 336 passes through the receiving groove 334 from the inside to the outside and is inserted into the adapter hole 351, thereby limiting the positioning rod 35 and keeping it stationary. Thus, the positioning rod 35 can be used to limit the crushed block 34 to the surface of the crushing disc 33, while simultaneously giving the crushed block 34 a certain shape. With its easy-to-replace feature, maintenance is more convenient. The end of the insertion rod 336 away from the positioning rod 35 is fixed with an operating handle 337. The operating handle 337 passes through the receiving groove 334 from the inside to the outside and extends to the outside of the support base 331. The operating handle 337 passes through the inside of the spring 335 without interfering with the spring 335. When maintenance is required, it is only necessary to manually pull the operating handle 337 to pull the insertion rod 336 out of the adapter hole 351 and then remove the positioning rod 35 from the placement groove 332. The crushed block 34 can then be separated from the support base 331 and replaced. The replacement of the crushed block 34 can be completed without the aid of any tools, making maintenance very convenient. Moreover, the maintenance process only requires the replacement of the crushed block 34 and does not require any adjustment to the entire crushing disc 33, thus reducing maintenance costs.
[0024] Please see Figure 5 A gap 37 is formed between the crushing block 34 on the first drive shaft 31 and the crushing block 34 on the second drive shaft 32, and the value of the gap 37 is between 1cm and 3cm.
[0025] Working principle: Please refer to the following again. Figures 1 to 5 In operation, the motor 21 drives the first drive gear 22 to rotate, which in turn drives the chain 24 to drive the first driven gear 23 to rotate, which in turn drives the second drive gear 25 and the second driven gear 26 to rotate, which in turn drives the first drive shaft 31 and the second drive shaft 32 to rotate, causing the four sets of crushing discs 33 to rotate. The crushed material is then added to the hopper 12. As the material falls into the crushing chamber 11, it is crushed by the four sets of crushing discs 33 and the crushing blocks 34 on them. As the crushing operation continues, some debris will adhere to the crushing blocks 34. This debris can be partially scraped off by the rotation of the adjacent crushing blocks 34 on the first drive shaft 31 and the second drive shaft 32, reducing the amount of manual cleaning required afterward.
[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
