[0019] Reference Figure 1~Figure 4 A permanent magnet variable frequency direct-drive grading crusher is proposed, comprising: a casing 1; a plurality of crushing rollers 2, which are rotatably arranged in the casing 1, and a crushing space 3 is formed between adjacent crushing rollers 2, and the crushing space 3 is used to squeeze and crush materials; a first driving member 4 is arranged on the casing 1, and the first driving member 4 is used to drive the crushing rollers 2 to rotate; a sliding frame 5 is slidably arranged on the casing 1, and the crushing rollers 2 are located below the sliding frame 5, and the sliding frame 5 is used to push the materials to be evenly arranged in the crushing space 3.

[0020] In this embodiment, the first driving member 4 is a permanent magnet variable frequency motor, a coupling and a synchronous gearbox. The housing 1 is fixed on a horizontal ground. The permanent magnet variable frequency motor, the synchronous gearbox and the crushing box are arranged on the housing 1. The output shaft of the permanent magnet variable frequency motor is connected to one of the crushing rollers 2 through a coupling. The remaining crushing rollers 2 transmit torque through the synchronous gearbox to ensure that the speeds of multiple crushing rollers 2 are the same, thereby effectively avoiding the slippage of materials. The permanent magnet variable frequency direct drive mode is adopted, which eliminates components such as hydraulic couplings and reducers, simplifies the transmission system, improves the transmission efficiency, and reduces energy loss. The permanent magnet variable frequency technology enables the speed and torque of the crusher to be adjusted more flexibly to meet different material crushing requirements, and improves the versatility and work efficiency of the equipment. The single first driving member 4 drives the crushing roller 2, which solves the problem of poor synchronization of the tooth roller when the dual motor is driven, reduces the slippage phenomenon when the crushing teeth bite the material, and especially improves the bite ability of large pieces of material, and enhances the crushing effect.

[0021] The sliding setting of the sliding frame 5 can actively promote the uniform arrangement of materials in the crushing space 3, so that the materials can be more fully squeezed and crushed by the crushing roller 2, and the uniformity and quality of crushing can be improved. If there are some large and relatively smooth materials that the crushing roller 2 cannot bite and crush well, the sliding of the sliding frame 5 can limit the position of the materials, and then cooperate with the crushing roller 2 to achieve crushing. The sliding frame 5 can also avoid the accumulation and blockage of materials in the crushing space 3, ensure the continuity and stability of the crushing process, and improve production efficiency. The crushing roller 2 can use its crushing capacity more effectively, reduce local excessive wear, and extend the service life of the crushing roller 2. It can adapt to different feed amounts and feed distributions, automatically adjust the distribution of materials, and enhance the adaptability of the crusher to different working conditions. Evenly arranging materials can reduce crushing energy consumption, improve energy utilization efficiency, and reduce production costs.

[0022] As a further technical solution, the housing 1 has a chamfer 6 , and the sliding frame 5 has a matching slope 7 , and the matching slope 7 has the same inclination angle as the chamfer 6 .

[0023] In this embodiment, the matching inclined surface 7 and chamfer 6 with the same inclination angle can achieve a good guiding effect, ensure that the sliding action of the sliding frame 5 on the casing 1 is accurate and avoids deviation, and can also reduce the friction loss during the sliding process, reduce energy consumption, and improve the operation economy of the equipment. When the crusher vibrates during operation, the structure with the same inclination angle can effectively reduce the impact of the vibration on the cooperation between the sliding frame 5 and the casing 1, and enhance the stability and reliability of the equipment. It is conducive to improving the assembly accuracy between the sliding frame 5 and the casing 1, thereby improving the manufacturing quality and performance of the entire crusher. It is convenient to check and clean the contact surface of the sliding frame 5 and the casing 1 during equipment maintenance, reduce the difficulty of maintenance, and shorten the maintenance time.

[0024] As a further technical solution, the crushing roller 2 includes: a main shaft 8 rotatably arranged on the casing 1; a plurality of blades 9 arranged at intervals in an array on the main shaft 8; a plurality of spacers 10 arranged at intervals in an array on the main shaft 8, and the blades 9 and the main shaft 8 are arranged in sequence.

[0025] In this embodiment, the main shaft 8 is rotatably arranged on the casing 1, providing stable support and rotational power for the blade 9, ensuring the smooth progress of the crushing work. Several blades 9 arranged at intervals in an array can increase the contact area with the material and improve the crushing efficiency and effect. The setting of the spacer 10 can adjust the spacing between the blades 9 to meet the crushing requirements of materials of different sizes, making the crushing more refined and uniform. The structure in which the blades 9 and the spacers 10 are arranged in sequence helps to balance the force on the main shaft 8 during rotation, reduce vibration and noise, and extend the service life of the main shaft 8. This structure facilitates the separate replacement and maintenance of the blades 9 and the spacers 10, reducing maintenance costs and time.

[0026] As a further technical solution, two adjacent crushing rollers 2 are arranged alternately.

[0027] In this embodiment, the two adjacent crushing rollers 2 are staggered, which can increase the number of crushing times and crushing paths of the material in the crushing space 3, thereby improving the adequacy and fineness of the crushing. This staggered layout can subject the material to more comprehensive squeezing and shearing, further improving the crushing effect and ensuring that the material is crushed more evenly. It helps to reduce the situation where the material is directly discharged without being fully crushed, and improves the working quality and product qualification rate of the crusher. It can better adapt to materials of different shapes and sizes, and improve the versatility and processing capacity of the crusher for materials. The staggered crushing rollers 2 can complement and cooperate with each other when working, reducing the load of a single crushing roller 2 and extending the service life of the crushing roller 2.

[0028] As a further technical solution, the spacer sleeve 10 has a plurality of dust removal holes 11 arranged at intervals on the circumference, the main shaft 8 has a through hole 12 , and the plurality of dust removal holes 11 are connected to the through hole 12 .

[0029] In this embodiment, the dust removal holes 11 arranged at intervals on the circumference of the spacer 10 are connected to the through hole 12 on the main shaft 8, forming an effective dust removal channel, which can timely discharge dust and fine particles during the crushing process, reduce the accumulation of dust in the crushing chamber, and improve the working environment. It helps to reduce the friction between the material and the crushing parts, reduce energy loss, and improve crushing efficiency. Timely discharge of dust can avoid dust wear and erosion on the crushing parts and extend the service life of the crusher. Good dust removal effect can ensure the quality of the material after crushing and reduce the impurity content. This structural design is simple and practical, does not add too many complex parts, and is easy to manufacture and maintain.

[0030] As a further technical solution, it also includes: a plurality of anti-blocking caps 13 are arranged on the spacer sleeve 10, and the anti-blocking caps 13 are located above the dust removal holes 11, and the anti-blocking caps 13 are used to prevent particles from entering and blocking the dust removal holes 11.

[0031] In this embodiment, the anti-blocking cap 13 is arranged above the dust removal hole 11, which can effectively block larger particles from entering the dust removal hole 11, prevent it from being blocked, ensure the smooth flow of the dust removal channel, and maintain a good dust removal effect. It reduces equipment failures and downtime for maintenance caused by the blockage of the dust removal hole 11, improves the operating stability and reliability of the equipment, and ensures the continuity of production. It avoids the increase in internal pressure caused by blockage, reduces the risk of equipment damage, and extends the service life of the crusher. It helps to maintain the air pressure balance in the crushing chamber, so that the crushing work can be carried out more stably and efficiently. The anti-blocking cap 13 has a simple structure, low cost, and is easy to install and maintain, and will not significantly increase the complexity and maintenance cost of the equipment.

[0032] As a further technical solution, one end of the anti-blocking cap 13 away from the spacer sleeve 10 is a conical surface 14, and the conical surface 14 is used to assist crushing.

[0033] In this embodiment, the end of the anti-blocking cap 13 away from the spacer sleeve 10 is a conical surface 14. During the crushing process, the conical surface 14 can contact with the material and play a certain auxiliary crushing role, increase the contact points and crushing angles of the crushing, and improve the crushing efficiency. The design of the conical surface 14 can make the material easier to disperse and flow during crushing, reduce the accumulation and congestion of the material in the crushing chamber, and help the smooth crushing and discharge of the material. When the material contacts the conical surface 14, it can produce a certain guiding effect, guiding the material to move to a position that is more conducive to crushing, and further optimize the crushing effect. The realization of the auxiliary crushing function does not require the addition of complex structures, and fully utilizes the shape characteristics of the anti-blocking cap 13, thereby improving the overall performance and utilization rate of the equipment. The presence of the conical surface 14 reduces the direct impact of the material on the anti-blocking cap 13, reduces the risk of wear and damage to the anti-blocking cap 13, and extends its service life.

[0034] As a further technical solution, the sliding frame 5 has a plurality of screw holes 15, and further includes: a plurality of screw rods 16, which are rotatably arranged on the housing 1, and the screw rods 16 are threadedly matched with the screw holes 15, and the screw rods 16 are used to drive the sliding frame 5 to slide; There are a plurality of second driving members 17 disposed on the housing 1 , and the second driving members 17 are used to drive the screw rod 16 to rotate.

[0035] In this embodiment, the screw hole 15 on the sliding frame 5 is threadedly matched with the screw rod 16. This transmission method has high precision and can accurately control the sliding distance and speed of the sliding frame 5 to ensure the uniform arrangement of the materials in the crushing space 3. The arrangement of multiple screw rods 16 and the second drive member 17 makes the force on the sliding frame 5 more uniform, the sliding process more stable, and reduces the possibility of jamming and tilting. The sliding frame 5 is driven to slide by the rotation of the screw rod 16, and the transmission efficiency is high. The power of the second drive member 17 can be effectively transmitted to the sliding frame 5, reducing energy loss.

[0036] As a further technical solution, the housing 1 has a protection cavity 18 , and the screw 16 is located in the protection cavity 18 . The protection cavity 18 is used to prevent materials from falling onto the screw 16 .

[0037] In this embodiment, the screw 16 is located in the protective cavity 18, which can effectively prevent the material from directly falling onto the screw 16 and damaging the screw thread, thereby affecting the sliding of the sliding frame 5, thereby improving the service life of the equipment.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
