DETAILED DESCRIPTION

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0030] This embodiment provides a roller type continuous curved block crusher with adjustable rolling distance and differential speed, such as Figure 1-Figure 5 As shown, the pair of rollers with adjustable rolling distance and differential speed continuous block crusher includes a first crushing unit 1, a second crushing unit 2, a third crushing unit 3, a shell 4 and a driving assembly (not shown in the figure). The first crushing unit 1 includes two first crushing rollers 11, and the two first crushing rollers 11 are used to crush the material for the first time. The second crushing unit 2 includes two second crushing rollers 21, and the two second crushing rollers 21 are used to crush the material for the second time. The third crushing unit 3 includes a third crushing roller 31 and a fourth crushing roller 32, and the third crushing roller 31 and the fourth crushing roller 32 are both provided with helical teeth 311, and the extension direction of the helical teeth 311 is at a preset angle with the rotation axis thereof, and the helical teeth 311 of the third crushing roller 31 and the helical teeth 311 on the fourth crushing roller 32 crush the material for the third time. A feed port 41 is provided on the upper side of the shell 4, and a discharge port 42 is provided on the lower side. The first crushing unit 1, the second crushing unit 2 and the third crushing unit 3 are arranged in the shell 4 from top to bottom in sequence. The driving assembly is used to drive the fourth crushing roller 32 to move in the horizontal direction so that the fourth crushing roller 32 approaches or moves away from the third crushing roller 31.

[0031] When the pair of roller type differential continuous block crusher with adjustable rolling distance is working, the material enters from the feed port 41 on the upper side of the shell 4, and the material falls into the first crushing unit 1. The two first crushing rollers 11 crush the material for the first time to initially reduce the size of the material; the material after the initial crushing falls into the second crushing unit 2, and is crushed for the second time by the two second crushing rollers 21 to further refine the material; then, the material enters the third crushing unit 3, and the driving component drives the fourth crushing roller 32 to move in the horizontal direction. According to the degree of crushing required for the material, the distance between the fourth crushing roller 32 and the third crushing roller 31 is adjusted, and the third crushing roller 31 and the fourth crushing roller 32 rotate relative to each other, and the oblique teeth 311 on the third crushing roller 31 and the oblique teeth 311 on the fourth crushing roller 32 interact with each other, and the extension direction of the oblique teeth 311 forms a preset angle with its own rotation axis, so that the material is crushed for the third time; finally, the crushed material is discharged from the discharge port 42 on the lower side of the shell 4. The double-roller type differential speed continuous block crusher with adjustable rolling distance can crush the materials thoroughly and evenly, crush a large number of qualified particles, have high production efficiency, reduce the transportation process, and reduce material loss and dust pollution.

[0032] Specifically, on the one hand, by adjusting the position of the fourth crushing roller 32, the distance between the third crushing roller 31 and the fourth crushing roller 32 can be flexibly changed according to the characteristics of different materials and the required crushing particle size, so that the double-roller type continuous curved block crusher with adjustable rolling distance and differential speed can realize the function of adjustable rolling distance, which can meet the crushing needs of various materials and improve the versatility and adaptability of the double-roller type continuous curved block crusher with adjustable rolling distance and differential speed. On the other hand, when encountering material blockage or needing to be cleaned, the drive assembly can easily pull the fourth crushing roller 32 apart, which is convenient for operation and maintenance, and reduces the failure and downtime of the double-roller type continuous curved block crusher with adjustable rolling distance and differential speed. Furthermore, this flexible adjustment method is conducive to controlling the crushing force, ensuring that the crushing effect of the material is uniform, thereby improving the working efficiency and product quality of the entire double-roller type continuous curved block crusher with adjustable rolling distance and differential speed, and bringing users a more efficient and convenient use experience.

[0033] like Figure 1-Figure 3 As shown, the double-roller type adjustable-gap differential continuous curved block crusher also includes a flap 5, which is arranged inside the shell 4, between the first crushing unit 1 and the second crushing unit 2 and between the second crushing unit 2 and the third crushing unit 3, and the flap 5 forms a preset angle with the horizontal direction. The flap 5 located between the first crushing unit 1 and the second crushing unit 2 can guide and buffer the material after being crushed by the first crushing unit 1, and can guide the material to enter the second crushing unit 2 more evenly. The flap 5 located between the second crushing unit 2 and the third crushing unit 3 can effectively adjust the flow direction and speed of the material after being crushed from the second crushing unit 2, so that the material can be more evenly distributed to the third crushing unit 3, avoiding the situation where local material accumulation or untimely processing occurs in the third crushing unit 3 due to rapid and large-scale influx of materials. Setting the flap 5 can adjust the falling speed and direction of the material, optimize the flow path of the material, and ensure the continuity and stability of the material in the entire crushing process, thereby improving the working stability and crushing efficiency of the entire double-roller type adjustable rolling distance differential speed continuous curved block crusher, and further improving the performance of the entire double-roller type adjustable rolling distance differential speed continuous curved block crusher.

[0034] In other embodiments, the flap 5 may also be disposed only between the first crushing unit 1 and the second crushing unit 2 or only between the second crushing unit 2 and the third crushing unit 3, which is not specifically limited herein.

[0035] like Figure 5-Figure 7As shown, the bevel teeth 311 include a blunt surface 3111 and a front surface 3112. The angle between the blunt surface 3111 and the tooth top circle radius line of the bevel teeth 311 is a first angle α, and the angle between the front surface 3112 and the tooth top circle radius line of the bevel teeth 311 is a second angle β, which is smaller than the first angle α. The two bevel teeth 311 on the third crushing roller 31 and the fourth crushing roller 32 are meshed with each other, and the front surface 3112 of one bevel tooth 311 fits with the front surface 3112 of the other bevel tooth 311. Due to the different angles of the front surface 3112 and the blunt surface 3111, the force distribution on the material during the crushing process is more reasonable, and the uniformity and crushing quality of the crushing are improved. The front surface 3112 is sharper, and the front surface 3112 of one bevel tooth 311 fits with the front surface 3112 of another bevel tooth 311, which can produce a stronger shearing and crushing effect on the material during crushing, and can more efficiently crush the material into the required particle size.

[0036] In some embodiments, the two mutually meshing bevel teeth 311 on the third crushing roller 31 and the fourth crushing roller 32, the blunt surface 3111 of one of the two bevel teeth 311 fits with the blunt surface 3111 of the other bevel tooth 311. The fit between the blunt surfaces 3111 can make the crushing process more stable and avoid the problem of excessive crushing of materials. It can ensure a certain crushing effect while making the crushing force on the material more uniform and gentle, especially for some materials with special requirements for crushing particle size, it can provide a more suitable crushing method. In addition, this design can also reduce the wear of the double-roller type continuous curved block crusher with adjustable rolling distance and differential speed during operation, extend the service life of the double-roller type continuous curved block crusher with adjustable rolling distance and differential speed, and help to improve the reliability and stability of the operation of the double-roller type continuous curved block crusher with adjustable rolling distance and differential speed.

[0037] In some other embodiments, the two mutually meshing helical teeth 311 on the third crushing roller 31 and the fourth crushing roller 32, the front surface 3112 of one of the two helical teeth 311 fits with the blunt surface 3111 of the other helical tooth 311. The sharpness of the front surface 3112 and the gentleness of the blunt surface 3111 are combined to achieve different crushing forces when crushing materials. The sharpness of the front surface 3112 can be used to effectively crush the materials, and the blunt surface 3111 can be used to buffer and adjust the crushing intensity, making the crushing process more flexible and diverse, better adapting to the characteristics of different materials, and improving the uniformity and crushing effect of material crushing, thereby improving the working performance of the entire double-roller type adjustable rolling distance differential continuous curved block crusher and the efficiency of material processing. Specifically, in actual setting, the front surface 3112 of the helical teeth 311 of the third crushing roller 31 can be made to fit with the blunt surface 3111 of the helical teeth 311 of the fourth crushing roller 32, or the blunt surface 3111 of the helical teeth 311 of the third crushing roller 31 can be made to fit with the front surface 3112 of the helical teeth 311 of the fourth crushing roller 32, without specific limitation here.

[0038] like Figure 5 and Figure 8 As shown, the third crushing unit 3 further includes a first reduction motor 33, a first synchronous wheel 35, a second synchronous wheel 36, a first transmission belt 37 and a first pulley 34. The third crushing roller 31 is connected to the output end of the first reduction motor 33 by transmission. The first synchronous wheel 35 is arranged at the end of the third crushing roller 31. The second synchronous wheel 36 is arranged in the housing 4 on the same side as the first synchronous wheel 35. The first transmission belt 37 is wound around the outer periphery of the first synchronous wheel 35 and the second synchronous wheel 36 and is tensioned by the first synchronous wheel 35 and the second synchronous wheel 36. The first pulley 34 is arranged at the end of the fourth crushing roller 32. The first pulley 34 is pressed against the outer wall of the first transmission belt 37. The movement of the first transmission belt 37 can drive the first pulley 34 to rotate. Firstly, the first reduction motor 33 provides power for the third crushing roller 31, ensuring a stable power source. The transmission system composed of the first synchronous wheel 35, the second synchronous wheel 36 and the first transmission belt 37 can effectively transmit power to the fourth crushing roller 32, and the transmission stability is ensured by the tensioned first transmission belt 37, reducing the energy loss in the power transmission process. Secondly, the first pulley 34 is pressed against the outer wall of the first transmission belt 37, and the movement of the first transmission belt 37 is used to drive the fourth crushing roller 32 to rotate, thereby realizing the coordinated work of the third crushing roller 31 and the fourth crushing roller 32, so that the two can cooperate efficiently to complete the crushing task.

[0039] It is worth noting that the diameter of the first pulley 34 is greater than the diameter of the first synchronous wheel 35. According to the basic principle of transmission ratio, due to the difference in diameter, when the third crushing unit 3 is working, the rotation speed of the third crushing roller 31 will be greater than the rotation speed of the fourth crushing roller 32, thereby realizing the function of adjustable roller differential speed of the double-roller type continuous curved block crusher with adjustable rolling distance and differential speed. It can flexibly adjust the working mode according to the characteristics of different materials and the required crushing particle size, ensure that the entire crushing process is more accurate and efficient, and also help to reduce the energy consumption of the double-roller type continuous curved block crusher with adjustable rolling distance and differential speed, extend the service life of the double-roller type continuous curved block crusher with adjustable rolling distance and differential speed, and enhance the adaptability and reliability of the double-roller type continuous curved block crusher with adjustable rolling distance and differential speed.

[0040] Specifically, the output end of the first reduction motor 33 is provided with a first driving wheel (not shown in the figure), one end of the third crushing roller 31 is provided with a first driven wheel 39, and the second transmission belt 38 is wound around the first driving wheel and the first driven wheel 39. When the first reduction motor 33 starts to work, the first driving wheel starts to rotate, driving the second transmission belt 38 to move, and the movement of the second transmission belt 38 transmits the rotational movement of the first driving wheel to the first driven wheel 39, thereby driving the first driven wheel 39 to start rotating, the third crushing roller 31 starts to rotate and drives the first synchronous wheel 35 to rotate, the first transmission belt 37 moves, the second synchronous wheel 36 moves, and further drives the first belt wheel 34 to rotate, and the fourth crushing roller 32 to rotate. This design can not only improve the crushing efficiency of the material, but also realize the control of the crushing effect of different materials through precise transmission ratio adjustment. Moreover, the various components are arranged inside the shell 4, which has a compact structure and is convenient for installation, maintenance and overhaul, thereby reducing the complexity and maintenance cost of the overall double-roller type continuous curved block crusher with adjustable rolling distance differential speed, improving the performance and reliability of the double-roller type continuous curved block crusher with adjustable rolling distance differential speed, and providing users with a better crushing solution.

[0041] In this embodiment, the driving assembly includes a driving motor, a screw rod and a nut. The screw rod is arranged in the horizontal direction and is connected to the output end of the driving motor. The nut is arranged at the end of the fourth crushing roller 32, and the nut is threadedly connected to the screw rod. The driving motor, as a power source, can provide stable and reliable power. The screw rod is arranged in the horizontal direction and is connected to the output end of the driving motor, ensuring the effective transmission of power. The precise transmission characteristics of this structure can achieve precise position control. A nut is arranged at the end of the fourth crushing roller 32 and is threadedly connected to the lead screw. When the driving motor drives the lead screw to rotate, the nut drives the fourth crushing roller 32 to move in the horizontal direction to achieve precise position adjustment, so that the fourth crushing roller 32 can flexibly approach or move away from the third crushing roller 31. Not only can the double-roll type adjustable-gap differential continuous curved block crusher adjust the distance between the third crushing roller 31 and the fourth crushing roller 32 according to different material properties and crushing requirements, but also the structure is simple and compact, easy to install and maintain, and at the same time, it can also achieve precise crushing force control, improve the accuracy and efficiency of material crushing, reduce the failure and wear of the double-roll type adjustable-gap differential continuous curved block crusher, and extend the service life of the double-roll type adjustable-gap differential continuous curved block crusher.

[0042] like Figure 1 , Figure 2 , Figure 4 and Fig. 9As shown, the first crushing unit 1 also includes a second reduction motor 12, and any one of the two first crushing rollers 11 is connected to the output end of the second reduction motor 12 in a transmission manner. The same end of the two first crushing rollers 11 is provided with a first gear 13, and the two first gears 13 are meshed with each other. The two first gears 13 at the same end of the two first crushing rollers 11 are meshed with each other, so that the two first gears 13 can operate synchronously, ensuring uniform crushing of the material in the first crushing stage, and avoiding the problem of uneven crushing of the material due to asynchrony. This structure not only improves the crushing efficiency, but also ensures that the material obtains a more consistent crushing effect when it is processed by the first crushing unit 1, laying a good foundation for the subsequent second crushing unit 2 and the third crushing unit 3 to further refine the material crushing, and improving the performance of the entire double-roll type adjustable-gap differential continuous curved block crusher.

[0043] Specifically, a second driving wheel (not shown in the figure) is provided at the output end of the second reduction motor 12, a first sprocket 15 is provided at one end of any one of the two first crushing rollers 11, and the first rack 14 is wound around the second driving wheel and the first sprocket 15. When the second reduction motor 12 starts to work, the second driving wheel starts to rotate, driving the first rack 14 to move, and the movement of the first rack 14 transmits the rotational movement of the second driving wheel to the first sprocket 15, thereby driving the first sprocket 15 to start rotating. The same end of the two first crushing rollers 11 is provided with a first gear 13, and the two first gears 13 are meshed with each other. When the first crushing roller 11 with the first sprocket 15 starts to rotate, the first gear 13 at the end of the first crushing roller 11 will drive the first gear 13 at the end of the other first crushing roller 11 to rotate synchronously, thereby realizing the synchronous operation of the two first crushing rollers 11, ensuring that the first crushing unit 1 has good coordination and stability in the crushing process of the material.

[0044] like Fig. 9 As shown, the first crushing roller 11 is constructed as a spike-tooth roller shaft, which includes a first roller body 111 and a first crushing tooth 112. The first roller body 111 is constructed as a cylindrical roller body, and the first crushing tooth 112 is constructed as a conical tooth. The first crushing tooth 112 is evenly distributed on the outer wall of the first roller body 111 along the circumferential direction and axial direction of the first roller body 111. The first crushing roller 11 is constructed as a spike-tooth roller shaft, and the first roller body 111 is cylindrical, which ensures stable rotation support. The first crushing teeth 112 are conical teeth, and the conical teeth are evenly distributed on the outer wall of the first roller body 111 along the circumferential and axial directions. This allows the material to be crushed from multiple angles during the material crushing process, thereby improving the contact probability and crushing efficiency between the material and the first crushing tooth 112. The design of the conical tooth can also enhance the crushing force and effect, making the material easier to be crushed, laying a good foundation for the efficient development of the entire crushing process, and at the same time improving the performance of the double-roller type adjustable rolling distance differential continuous curved block crusher in the initial crushing stage.

[0045] like Figure 1 , Figure 2 , Figure 4 and Fig.10 As shown, the second crushing unit 2 also includes a third reduction motor 22, and any one of the two second crushing rollers 21 is connected to the output end of the third reduction motor 22 by transmission, and the same end of the two second crushing rollers 21 is provided with a second gear 23, and the two second gears 23 are meshed with each other. The third reduction motor 22 provides power for the two second crushing rollers 21, ensuring the normal operation of the second crushing process. The second gears 23 meshing with each other set at the same end of the two second crushing rollers 21 ensure their synchronous rotation, which helps to apply force evenly when crushing materials and avoid uneven crushing of materials due to asynchrony. Such a structural design can effectively improve the working efficiency of the second crushing unit 2, ensure that the material can be stably and evenly crushed during the second crushing, and enhance the crushing effect and working performance of the entire double-roll type adjustable-gap differential continuous curved block crusher.

[0046] Specifically, a third driving wheel (not shown in the figure) is provided at the output end of the third reduction motor 22, a second sprocket 25 is provided at any one of the two second crushing rollers 21, and the second rack 24 is wound around the third driving wheel and the second sprocket 25. When the third reduction motor 22 starts to run, the third driving wheel starts to rotate, driving the second rack 24 to move accordingly, and the movement of the second rack 24 transmits the rotational movement of the third driving wheel to the second sprocket 25, thereby driving the second sprocket 25 to start rotating. A second gear 23 is provided at the same end of the two second crushing rollers 21, and the two second gears 23 are meshed with each other. When the second crushing roller 21 equipped with the second sprocket 25 rotates, the second gear 23 at the end of the second crushing roller 21 will mesh with the second gear 23 at the end of the other second crushing roller 21, so that the other second crushing roller 21 also rotates synchronously, ensuring the coordinated work of the two second crushing rollers 21.

[0047] like Fig.10As shown, the second crushing roller 21 is constructed as a toothed blade roller shaft, which includes a second roller body 211, a crushing disk 213 and a second crushing tooth 212. The second roller body 211 is constructed as a cylindrical roller body, and the crushing disk 213 is arranged on the second roller body 211 at intervals along the axial direction of the second roller body 211. The second crushing teeth 212 are constructed in a sawtooth shape, and the second crushing teeth 212 are arranged at intervals in the circumferential direction of the crushing disk 213. The second roller body 211 adopts a cylindrical design to provide stable support for the crushing process. The crushing disks 213 are arranged on the second roller body 211 at intervals along the axial direction, and serrated second crushing teeth 212 are provided in the circumferential direction. This design enables the crushing disks 213 to increase the crushing chance of the material when the material passes through the second crushing unit 2, and the serrated second crushing teeth 212 enhance the crushing ability of the material, and can crush the material more finely and fully, thereby improving the crushing effect and efficiency of the second crushing unit 2, thereby improving the performance of the entire double-roll type differential continuous curved block crusher with adjustable rolling distance, and ensuring that the material is crushed more evenly and finely.
