Description

Technical Field

[0001] This utility model relates to the field of palm crusher technology, and in particular to a rotor cavity for a palm crusher. Background Technology

[0002] Palm fiber, having withstood the elements in its natural environment, possesses a unique structure that endows it with exceptional toughness and resistance to breakage. Looking at its fiber structure, the tightly interwoven fiber bundles resemble a tightly woven rope, layered and mutually supporting each other. This allows the palm fiber to evenly distribute force when subjected to external impacts, effectively resisting stress concentrations that could lead to breakage. This is the intrinsic reason why it is not easily broken.

[0003] For example, patent CN213996185U discloses a palm kernel crusher. The housing is made up of a front plate, a rear plate, and an arc plate connected and fixed together by an upper fixed plate and a lower fixed plate. The front plate, the rear plate, and the motor are mounted on the base. The motor is connected to the drive wheel, and the drive wheel is connected to the driven wheel. The transmission shaft is installed in the first adjusting plate, and the second adjusting plate is installed on the outer side of the rear plate. A through hole is opened on the front plate corresponding to the center hole of the first adjusting plate, and a through hole is opened on the rear plate corresponding to the second adjusting plate. The transmission shaft is installed in the center hole of the second adjusting plate. The transmission shaft is equipped with a rotor disc. Multiple rotors are evenly distributed on the circumference of the rotor disc. Multiple left stators and right stators are evenly distributed on the inner surface of the arc plates on both sides of the rotor. The two ends of the left stators and right stators are mounted on the front plate and the rear plate.

[0004] In the above scheme, the long fibers of palm are very easy to get tangled on the rotor and stator of the crusher, hindering the normal rotation of the components, and in severe cases, the crushing process may be forced to stop. Utility Model Content

[0005] To address the problem that the long fibers of palm trees easily get tangled on the rotor and stator of a crusher, hindering the normal rotation of the components, this utility model provides a rotor cavity for a palm crusher.

[0006] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0007] A palm fiber crusher rotor chamber includes a housing and a rotor rotatably disposed inside the housing. The rotor includes a rotating shaft with both ends rotatably mounted on the inner wall of the housing. A fixed housing is fixedly mounted on the rotating shaft. A plurality of sets of crushing blades and a plurality of sets of shredding blades are evenly arranged along the circumferential direction on the outer wall of the fixed housing. The crushing blade sets and shredding blade sets are staggered. Mounting plates are fixedly mounted on both ends of the fixed housing. Each shredding blade set includes a mounting shaft. The end of the mounting shaft is detachably mounted on the mounting plate. A plurality of sawing gears are evenly arranged along the length of the mounting shaft. This palm fiber crusher rotor chamber, through the fixed housing fixedly mounted on the rotating shaft and the staggered arrangement of the crushing blade sets and shredding blade sets, combined with the evenly distributed sawing gears on the mounting shafts of the shredding blade sets, effectively crushes the palm fiber while the sawing gears shred the palm fiber, effectively reducing the occurrence of fiber entanglement on the rotor and stator, ensuring the normal rotation of the crusher components, and ensuring the continuous and stable crushing process.

[0008] Preferably, the mounting shaft end is bolted to the mounting plate. This bolted connection facilitates quick disassembly and installation of the shredder assembly. When the saw gears become worn or damaged, the operator can promptly change the mounting angle of the mounting shaft, utilizing the unworn sections of the saw gears to extend their service life.

[0009] Preferably, several sets of limiting blocks are evenly arranged along the circumferential direction on the inner wall of the casing; each set of limiting blocks includes several bosses spaced apart along the length of the rotating shaft; the bosses and saw gears are staggered. The limiting blocks evenly arranged along the circumferential direction on the inner wall of the casing, with the bosses spaced apart along the length of the rotating shaft in each set and staggered with the saw gears, can limit and block the palm material after it enters the rotor cavity, allowing the material to make more full contact with the saw gears in the rotor cavity, thus improving the crushing effect; at the same time, this staggered structure helps to disrupt the direction of the palm fiber, avoid fiber entanglement and aggregation, and further crush the fiber with the saw gears, reducing the risk of fiber entanglement in the rotor components, ensuring stable operation of the crusher, and improving crushing efficiency.

[0010] Preferably, the fixed housing is provided with a clearance groove to accommodate the chopping blade assembly. This clearance groove provides ample space for the installation of the chopping blade assembly, effectively preventing interference and collision between the chopping blade assembly and the fixed housing during operation, thus ensuring the efficient and stable operation of the crusher.

[0011] Preferably, a receiving groove is provided on the fixed housing to accommodate the crushing blade assembly; the receiving groove is located between the crushing blade assembly and the shredding blade assembly. The receiving groove on the fixed housing between the crushing blade assembly and the shredding blade assembly allows the palm material to extend into the receiving groove when it is fed into the rotor, facilitating the crushing of the palm material by the crushing blade assembly.

[0012] Preferably, the crusher blade assembly includes a mounting base; blades are mounted on the mounting base via a clamping block; the clamping block is mounted on the mounting base via bolts. The crusher blade assembly uses a combination of mounting base, clamping block, and bolts for installation, resulting in a simple and stable structure. Fixing the blades to the mounting base via the clamping block and bolts not only ensures the blades remain stable during high-speed crushing, preventing loosening and detachment and guaranteeing the safety of the crushing operation, but also allows operators to quickly unscrew the bolts and remove the clamping block when the blades wear or are damaged, facilitating convenient blade replacement. This effectively reduces maintenance and time costs, ensuring the crusher maintains excellent crushing performance and continuous, efficient operation.

[0013] Preferably, the distance from the blade tip to the center line of the rotating shaft is less than the distance from the outer edge of the saw gear to the center line of the rotating shaft. This design creates a layered crushing structure. After the material enters the rotor cavity, the outer saw gear cuts the palm fiber, reducing fiber length and the risk of entanglement; the inner blade, in conjunction with the receiving groove, cuts the palm material. This layered crushing method fully utilizes the advantages of both the saw gear and the blade, effectively preventing material from accumulating due to insufficient processing, greatly improving palm crushing efficiency and ensuring stable operation of the crusher.

[0014] Preferably, the distance from the top surface of the boss to the center line of the rotating shaft is greater than the distance from the blade tip to the center line of the rotating shaft. This height difference design optimizes the movement trajectory and crushing process of the material within the rotor cavity. After the palm material enters the rotor cavity, the higher boss can block and limit the material, ensuring it fully contacts the saw gear and is crushed, preventing the material from directly impacting the blade and causing blockage.

[0015] As can be seen from the above technical solutions, the advantages of this utility model include: the rotor chamber of the palm crusher uses a fixed housing fixedly installed on the rotating shaft to stagger the crushing blade group and the shredding blade group, and with the evenly distributed saw gears on the shredding blade group mounting shaft, it can effectively crush the palm while the saw gears can shred the palm fiber, effectively reducing the occurrence of fiber entanglement on the rotor and stator, ensuring the normal rotation of the crusher components, and ensuring the continuous and stable crushing process.

[0023] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0024] like Figure 1 and Figure 2 As shown, a palm fiber crusher rotor chamber includes a housing 1 and a rotor 2 rotatably disposed inside the housing 1. The rotor 2 includes a rotating shaft 201 with both ends rotatably disposed on the inner wall of the housing 1. A fixed housing 202 is fixedly installed on the rotating shaft 201. Several sets of crushing blade groups 3 and several sets of chopping blade groups 4 are evenly arranged along the circumferential direction on the outer wall of the fixed housing 202. The crushing blade groups 3 and chopping blade groups 4 are staggered. Mounting plates 203 are fixedly installed at both ends of the fixed housing 202. The chopping blade group 4 includes a mounting shaft 401. The end of the mounting shaft 401 is detachably disposed on the mounting plate 203. Several sawing gears 402 are evenly arranged along the length direction on the mounting shaft 401.

[0025] The rotor chamber of this palm crusher uses a fixed housing 202 fixedly installed on the rotating shaft 201 to stagger the crushing blade group 3 and the shredding blade group 4. With the evenly distributed saw gears 402 on the shredding blade group mounting shaft 401, the palm can be effectively crushed while the saw gears 402 can shred the palm fibers. This effectively reduces the occurrence of fibers entangled in the rotor and stator, ensures the normal rotation of the crusher components, and ensures the continuous and stable crushing process.

[0026] The mounting shaft 401 is bolted to the mounting plate 203 at its end. This detachable connection facilitates quick disassembly and installation of the chopping blade assembly 4. When the saw gear 402 becomes worn or damaged, the operator can promptly change the mounting angle of the mounting shaft 401, utilizing the unworn portion of the saw gear 402 to extend its service life. A clearance groove 204 is provided on the fixed housing 202 to accommodate the chopping blade assembly 4. A receiving groove 205 is provided on the fixed housing 202 to accommodate the crushing blade assembly 3; the receiving groove 205 is located between the crushing blade assembly 3 and the chopping blade assembly 4. The clearance groove 204 on the fixed housing 202 provides ample space for the installation of the chopping blade assembly 4, effectively preventing interference and collision between the chopping blade assembly 4 and the fixed housing 202 during operation, ensuring efficient and stable operation of the crusher. A receiving groove 205 is provided on the fixed housing 202 between the crushing blade group 3 and the shredding blade group 4, so that when the palm material is fed into the rotor 2, the palm material can extend into the receiving groove 205, which facilitates the crushing of the palm material by the crushing blade group 3.

[0027] like Figure 3 As shown, the crusher assembly 3 includes a mounting base 301; blades 302 are mounted on the mounting base 301 via a clamping block 303; the clamping block 303 is mounted on the mounting base 301 by bolts. The crusher assembly 3 adopts a simple and stable installation method using a combination of mounting base 301, clamping block 303, and bolts. By fixing the blades 302 to the mounting base 301 with the clamping block 303 and bolts, not only is it ensured that the blades 302 remain stable during high-speed crushing, preventing loosening and falling off, and ensuring the safety of the crushing operation; but also, when the blades 302 become worn or damaged, the operator can quickly unscrew the bolts and remove the clamping block 303 to conveniently replace the blades 302, effectively reducing maintenance and time costs, ensuring that the crusher always maintains good crushing performance and continuous efficient operation.

[0028] like Figure 4As shown, several sets of limiting blocks are evenly arranged along the circumferential direction on the inner wall of the casing 1; each set of limiting blocks includes several protrusions 101 spaced apart along the length of the rotating shaft 201; the protrusions 101 and the saw gears 402 are staggered. The limiting blocks evenly arranged along the circumferential direction on the inner wall of the casing 1 are not mentioned in the original text and have no corresponding markings. The protrusions 101 spaced apart along the length of the rotating shaft 201 in each set are staggered with the saw gears 402. After the palm material enters the rotor cavity, the protrusions 101 can limit and block the material, allowing the material to contact the saw gears 402 more fully in the rotor cavity, improving the crushing effect; at the same time, this staggered structure helps to disrupt the direction of the palm fiber, avoid fiber entanglement and aggregation, and further crush the fiber with the saw gears 402, reducing the risk of fiber entanglement in the rotor 2 components, ensuring stable operation of the crusher and improving crushing efficiency.

[0029] In the above configuration, the distance from the tip of the blade 302 to the center line of the rotating shaft 201 is less than the distance from the outer edge of the saw gear 402 to the center line of the rotating shaft 201. The distance from the top surface of the boss 101 to the center line of the rotating shaft 201 is greater than the distance from the tip of the blade 302 to the center line of the rotating shaft 201.

[0030] The distance from the tip of blade 302 to the center line of shaft 201 is less than the distance from the outer edge of saw gear 402 to the center line of shaft 201. This design creates a layered crushing structure. After the material enters the rotor cavity, the outer saw gear 402 cuts the palm fiber, reducing fiber length and the risk of entanglement. The inner blade 302, in conjunction with the receiving groove 205, cuts the palm material. This layered crushing method fully utilizes the advantages of both saw gear 402 and blade 302, effectively preventing material accumulation due to insufficient processing, greatly improving palm crushing efficiency and ensuring stable operation of the crusher. The distance from the top surface of boss 101 to the center line of shaft 201 is greater than the distance from the tip of blade 302 to the center line of shaft 201. This height difference design optimizes the material's movement trajectory and crushing process within the rotor cavity. After the palm material enters the rotor cavity, the higher boss 101 can block and limit the material, ensuring it fully contacts and is cut by the saw gear 402, preventing the material from directly impacting the blade 302 and causing blockage.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
