[0003] Most existing crushers adopt a single-shaft rotating crushing roller structure. Its working principle is to use a single roller shaft to drive hammers, blades, or toothed rollers to impact, squeeze, or shear the material. Although this structure is simple and easy to maintain, the crushing force is concentrated in one direction, making it difficult to achieve multi-angle crushing, resulting in some materials being difficult to effectively crush. Utility Model Content

[0004] The purpose of this invention is to provide a multi-stage crushing component and a universal crusher to address the problem mentioned in the background art that most existing crushers adopt a single-shaft rotating crushing roller structure. Their working principle involves a single roller shaft driving hammers, blades, or toothed rollers to impact, squeeze, or shear materials for crushing. While this structure is simple and easy to maintain, the crushing force is concentrated in a single direction, making multi-angle crushing difficult and resulting in some materials being difficult to effectively crush.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage crushing assembly, comprising a shell and a crushing section:

[0006] The outer casing has a crushing chamber for accommodating crushed materials. The crushing part is located inside the outer casing and is used for multi-stage crushing of materials. The crushing part has a rotating frame rotatably arranged inside the outer casing. Several crushing shafts are rotatably arranged inside the rotating frame. The crushing shafts are meshed with the outer casing. The rotating frame rotates under the drive of an external power source and drives the crushing shafts to revolve around the rotating frame, thereby driving the crushing shafts to rotate and improve the crushing efficiency and uniformity of the materials.

[0007] By adopting the above technical solution, the rotating frame can drive the crushing shaft. While the rotating frame drives the crushing shaft to revolve, the crushing shaft rotates on its own axis, so that the material is subjected to multi-angle shearing and impact inside the shell, thereby improving the crushing uniformity and efficiency.

[0008] Preferably, the crushing section also has a rotating groove inside the rotating frame, and the crushing shaft is embedded in the rotating groove and rotatably connected to the rotating frame by means of a bearing or sliding fit.

[0009] By adopting the above technical solutions, it can be ensured that the crushing shaft operates stably within the rotating frame, reducing vibration and wear, and extending the service life of the equipment.

[0010] Preferably, there are four crushing shafts, and the four crushing shafts are arranged in a central rotational symmetry structure around the rotation center of the rotating frame.

[0011] By adopting the above technical solutions, the crushing force can be evenly distributed, avoiding excessive force on one side that could lead to equipment imbalance, and improving the uniformity of material crushing.

[0012] Preferably, the housing also has a transmission tooth set around the inner wall of the housing, and a transmission gear is provided at one end of the crushing shaft, which meshes with the transmission tooth.

[0013] By adopting the above technical solution, the meshing action of the transmission gear and the transmission clamp can be used to make the crushing shaft rotate on its own axis while revolving around the central axis, thereby enhancing the crushing effect.

[0014] Preferably, the crushing section also has a plurality of crushing plates disposed at one end of the crushing shaft, the plurality of crushing plates having a central rotational symmetry structure around the rotation center of the crushing shaft.

[0015] By adopting the above technical solutions, the contact area between the crushing plate and the material can be increased, the shearing and impact efficiency can be improved, and the material can be crushed more thoroughly.

[0016] Preferably, the surface of the crushing plate is provided with a Teflon coating.

[0017] By adopting the above technical solutions, material adhesion to the crushing plate can be reduced, cleaning difficulty can be lowered, wear resistance can be improved, and the service life of the crushing plate can be extended.

[0018] A universal pulverizer includes a housing and the aforementioned multi-stage pulverizing components, and the universal pulverizer also includes a machine body.

[0019] The machine body has a crushing chamber inside, and the outer shell is fixedly installed inside the crushing chamber. The machine body has a discharge port on its side, and the outer shell has a connection port inside that communicates with the discharge port. The machine body has a power source on its side that is connected to the rotating frame.

[0020] By adopting the above technical solution, the material can be efficiently crushed in the crushing chamber and then smoothly discharged through the connection port and discharge port.

[0021] Preferably, the machine body also has a rotating door on the side of the machine body, and a hopper is provided on the side of the rotating door, which is in communication with the inner cavity of the outer shell.

[0022] By adopting the above technical solution, materials can be quickly fed into the interior of the shell through the hopper.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting up a crushing part, the rotating frame can drive the crushing shaft. While the crushing shaft revolves around the center, it also rotates on its own axis, so that the material is subjected to multi-angle shearing and impact inside the shell, thereby improving the crushing uniformity and efficiency. The rotating frame is driven to rotate, and the rotating frame drives multiple crushing shafts to revolve around its center. At the same time, since the transmission gear on the crushing shaft meshes with the transmission teeth on the inner wall of the shell, the crushing shaft rotates on its own axis while revolving around the center, driving the crushing plate to rotate at high speed to complete the crushing operation.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1

[0033] Please see Figure 1 , Figure 2 and Figure 3This embodiment provides a technical solution: a multi-stage crushing assembly, including a housing 1 and a crushing section 2.

[0034] The outer shell 1 has a crushing chamber for accommodating crushed materials. The crushing part 2 is located inside the outer shell 1 and is used for multi-stage crushing of materials. The crushing part 2 has a rotating frame 201 rotatably arranged inside the outer shell 1. Several crushing shafts 203 are rotatably arranged inside the rotating frame 201. The crushing shafts 203 are meshed with the outer shell 1. The rotating frame 201 rotates under the drive of an external power source and drives the crushing shafts 203 to revolve around the rotating frame 201, thereby driving the crushing shafts 203 to rotate on their own axis to improve the crushing efficiency and uniformity of the materials. It can be realized that the rotating frame 201 drives the crushing shafts 203 to revolve around the rotating frame 201 while the crushing shafts 203 rotate on their own axis, so that the materials are subjected to multi-angle shearing and impact inside the outer shell 1, thereby improving the crushing uniformity and efficiency.

[0035] Example 2

[0036] Please see Figure 4 , Figure 5 and Figure 6 This embodiment provides a technical solution: a multi-stage crushing assembly, including a crushing section 2, a rotating frame 201, and a crushing shaft 203.

[0037] A rotating groove 202 is provided inside the rotating frame 201. The crushing shaft 203 is embedded in the rotating groove 202 by means of bearing or sliding fit and is rotatably connected to the rotating frame 201. This can ensure that the crushing shaft 203 operates stably in the rotating frame 201, reduce vibration and wear, and extend the service life of the equipment.

[0038] There are four crushing shafts 203. The four crushing shafts 203 are arranged in a central rotational symmetry structure around the rotation center of the rotating frame 201. This can make the crushing force evenly distributed, avoid excessive force on one side causing equipment imbalance, and improve the uniformity of material crushing.

[0039] A transmission tooth 102 is arranged around the inner wall of the outer casing 1, and a transmission gear 204 is arranged at one end of the crushing shaft 203. The transmission gear 204 is meshed with the transmission tooth 102. The meshing action of the transmission gear 204 and the transmission tooth 102 can be used to make the crushing shaft 203 rotate on its own axis while revolving around the revolution, thereby enhancing the crushing effect.

[0040] Several crushing plates 205 are fixedly installed at one end of the crushing shaft 203. The fixing method is the existing detachable fixing, such as bolt connection, snap connection, etc. The several crushing plates 205 are arranged in a central rotational symmetry structure around the rotation center of the crushing shaft 203, which can increase the contact area between the crushing plates 205 and the material, improve the shearing and impact efficiency, and make the material crushed more thoroughly.

[0041] The surface of the crushing plate 205 is coated with Teflon, which can reduce the adhesion of materials to the crushing plate 205, reduce the difficulty of cleaning, improve wear resistance, and extend the service life of the crushing plate 205.

[0042] Example 3

[0043] Please see Figure 1 , Figure 2 and Figure 3 This embodiment also provides another technical solution: a universal pulverizer, including a body 3:

[0044] The machine body 3 has a crushing chamber 301 inside, and the outer shell 1 is fixedly installed inside the crushing chamber 301. The side of the machine body 3 has a discharge port 304. The inside of the outer shell 1 has a connection port 101 that communicates with the discharge port 304. The side of the machine body 3 has a power source that is connected to the rotating frame 201. This allows the material to be efficiently crushed in the crushing chamber 301 and then smoothly discharged through the connection port 101 and the discharge port 304.

[0045] A rotating door 302 is provided on the side of the machine body 3. The rotating door 302 is also equipped with a locking structure. A hopper 303 is provided on the side of the rotating door 302. The hopper 303 is connected to the inner cavity of the outer shell 1. Materials can be quickly fed into the interior of the outer shell 1 through the hopper 303.

[0046] Working principle: First, the material to be crushed is fed into the crushing chamber inside the outer shell 1 through the hopper 303. The power source is started to drive the rotating frame 201 to rotate. The rotating frame 201 drives multiple crushing shafts 203 to revolve around its center. At the same time, since the transmission gears 204 on the crushing shafts 203 mesh with the transmission teeth 102 on the inner wall of the outer shell 1, the crushing shafts 203 rotate on their own axis while revolving around the center, driving the crushing plate 205 to rotate at high speed. Under the combined motion of the rotating frame 201 and the crushing shafts 203, the material is subjected to multi-angle shearing, impact and extrusion, and is gradually crushed to the required particle size. The crushed material is discharged through the connection port 101 of the outer shell 1 and the discharge port 304 of the machine body 3. After crushing is completed, the flip door 302 can be opened for equipment cleaning or maintenance.
