Description

Technical Field

[0001] This utility model relates to the field of crusher equipment technology, and in particular to a high-efficiency compound crusher. Background Technology

[0002] A crusher is an important piece of machinery used for crushing materials. It is widely used in many fields such as mining, metallurgy, building materials, highways, railways, water conservancy and chemical industries. It can crush materials into small particles of different sizes to meet various industrial needs.

[0003] The most widely used type is the roller crusher. Roller crushers utilize the friction of the roller surfaces to draw material into the crushing zone, where it is crushed through compression or splitting. However, in practical applications, traditional roller crushers face challenges in terms of crushing efficiency and effectiveness when dealing with materials of varying sizes. When encountering large pieces of material, these materials tend to roll at the top of the crushing rollers, making it difficult for them to smoothly enter the gap between the rollers and complete the crushing process using the friction of the roller surfaces, resulting in low crushing efficiency. On the other hand, for smaller materials, once they fall into the narrow space between the crushing rollers and the housing, they will... Frequent bouncing caused by the rotation of the crushing rollers makes it difficult for the material to effectively enter between the two rollers for crushing, which also affects the thoroughness of crushing. Therefore, existing roller crushers equipped with only two rollers often find that some large and small materials remain inside after completing the crushing task. These materials have not been effectively crushed for various reasons. To solve this problem, manual assistance is often required. Tools are used to manually guide these residual materials into the space between the two rollers to complete the final crushing operation. This not only increases the labor intensity of the operators, but also affects the overall production efficiency and automation level.

[0004] Furthermore, we disclose a high-efficiency compound crusher to meet the practical needs of existing roller crushers that require operator assistance when crushing both large and small materials. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a high-efficiency compound crusher to solve the problem that existing roller crushers require operator assistance when crushing larger and smaller materials.

[0006] To achieve the above objectives, this utility model provides a high-efficiency compound crusher, including a working frame. A secondary crushing box is fixedly connected to one side of the upper end of the working frame. Two sets of crushing rollers are arranged inside the secondary crushing box. A drive assembly is arranged on one side of the secondary crushing box. The drive assembly is used to drive the two sets of crushing rollers to rotate and complete the crushing work. The two sets of crushing rollers are composed of two first crushing rollers and two second crushing rollers. The two second crushing rollers are rotatably connected to one side of the lower middle part of the secondary crushing box. The two first crushing rollers are rotatably connected to both sides of the upper end of the secondary crushing box. The first crushing rollers are located on the upper side of the second crushing rollers to prevent small-volume materials from falling between the crushing rollers and the working frame. A primary crushing box is fixedly connected to the upper end of the secondary crushing box. An impact assembly is arranged inside the primary crushing box. The impact assembly is used to break down large-volume materials into small pieces.

[0007] Preferably, baffles are fixedly connected to the upper ends of both sides of the interior of the secondary crushing box, and the baffles are used to guide the falling material into the space between the two second crushing rollers.

[0008] Preferably, the drive assembly includes two drive motors, which are respectively disposed at both ends of one side end face of the re-crushing chamber. The output end of each drive motor extends into the interior of the re-crushing chamber and is fixedly connected to a drive gear. The upper end of the drive gear is meshed with a first driven gear. One end of the first driven gear is fixedly connected to a first crushing roller inside the re-crushing chamber via a drive shaft. One side of the drive gear is meshed with a second driven gear. One end of the second driven gear is fixedly connected to a second crushing roller inside the re-crushing chamber via a drive shaft.

[0009] Preferably, the impact assembly includes two connecting rods, which are L-shaped. A toothed block is fixedly connected to one end of each connecting rod on one side. The toothed blocks on the two connecting rods are arranged opposite each other, and a drive gear is meshed between the toothed blocks on the two connecting rods. A connecting plate is fixedly connected to the middle of one side of the primary crushing box. A servo motor is provided at the lower end of the connecting plate, and the output end of the servo motor is fixedly connected to the drive gear.

[0010] Preferably, the impact assembly further includes two top plates located inside the primary crushing chamber. Each of the two top plates has a crushing plate fixedly connected to its end face that contacts the material. The surface of the crushing plate is irregular.

[0011] Preferably, sliding columns are fixedly connected to both ends of the top plate on the side away from the crushing plate, a buffer spring seat is fixedly connected to one end of the sliding column, the end of the buffer spring seat away from the sliding column is fixedly connected to a positioning column, the end of the positioning column away from the buffer spring seat is fixedly connected to a connecting rod, and guide plates are fixedly connected to both sides of the inner middle part of the primary crushing box.

[0013] The beneficial effects of this utility model are:

[0014] This high-efficiency compound crusher features a main body supported by a working frame, with a secondary crushing box located on one side of its upper end. This design overcomes the limitations of traditional roller crushers in handling materials of different sizes. Inside the secondary crushing box, two sets of crushing rollers—two first crushing rollers and two second crushing rollers—are installed. This double-layer crushing roller configuration not only enhances crushing capacity but also effectively prevents small-volume materials from bouncing and falling into the gap between the crushing rollers and the working frame, ensuring that all materials are thoroughly crushed. Furthermore, a preliminary crushing box is added above the secondary crushing box, equipped with an impact component. This component pre-decomposes large-volume materials into smaller pieces, preparing them for subsequent fine crushing and significantly reducing the working pressure on the secondary crushing box. It also solves the problem of large materials being unable to directly enter the gap between the crushing rollers. Through this structural design, the high-efficiency compound crusher not only significantly improves crushing efficiency but also ensures that both large and small materials are thoroughly crushed without manual assistance, achieving automation and high efficiency in the crushing operation.

[0025] like Figures 1 to 5As shown, a high-efficiency compound crusher includes a working frame 1. A secondary crushing box 2 is fixedly connected to one side of the upper end of the working frame 1. Two sets of crushing rollers are arranged inside the secondary crushing box 2. A drive assembly is arranged on one side of the secondary crushing box 2. The drive assembly is used to drive the two sets of crushing rollers to rotate and complete the crushing work. The two sets of crushing rollers are composed of two first crushing rollers 14 and two second crushing rollers 15. The two second crushing rollers 15 are rotatably connected to one side of the lower middle part of the interior of the secondary crushing box 2. The two first crushing rollers 14 are rotatably connected to both sides of the upper end of the interior of the secondary crushing box 2. The first crushing rollers 14 are located on the upper side of the second crushing rollers 15 to prevent small-volume materials from falling between the crushing rollers and the working frame 1. A primary crushing box 5 is fixedly connected to the upper end of the secondary crushing box 2. An impact assembly is arranged inside the primary crushing box 5. The impact assembly is used to decompose large-volume materials into small pieces.

[0026] The main body of the crusher is supported by a working frame 1, with a secondary crushing box 2 installed on one side of its upper end. This design overcomes the limitations of traditional roller crushers in processing materials of different sizes. Inside the secondary crushing box 2, two sets of crushing rollers are configured—two first crushing rollers 14 and two second crushing rollers 15. This double-stage crushing roller configuration not only enhances the crushing capacity, but the placement of the first crushing rollers 14 on the upper side of the second crushing rollers 15 effectively prevents small-volume materials from falling into the gap between the crushing rollers and the working frame 1 due to bouncing, ensuring that all materials are fully crushed. In addition, a preliminary crushing box 5 is added above the secondary crushing box 2, equipped with an impact component. This component can pre-decompose large-volume materials into smaller pieces, preparing them for subsequent fine crushing and greatly reducing the working pressure on the secondary crushing box 2. It also solves the problem that large pieces of material cannot directly enter the gap between the crushing rollers. Through the above structural design, the high-efficiency compound crusher not only significantly improves the crushing efficiency, but also ensures that both large and small-sized materials can be thoroughly crushed without manual assistance, achieving automation and high efficiency in the crushing operation.

[0027] Furthermore, such as Figure 1 and Figure 5As shown, baffles 20 are fixedly connected to the upper ends of both sides of the interior of the secondary crushing box 2. The baffles 20 are used to guide the falling material into the space between the two second crushing rollers 15. The drive assembly includes two drive motors 6, which are respectively set at both ends of one side end face of the secondary crushing box 2. The output end of the drive motor 6 extends into the interior of the secondary crushing box 2 and is fixedly connected to a drive gear 17. The upper end of the drive gear 17 is meshed with a first driven gear 16. One end of the first driven gear 16 is fixedly connected to the first crushing roller 14 inside the secondary crushing box 2 through a drive shaft. One side of the drive gear 17 is meshed with a second driven gear 18. One end of the second driven gear 18 is fixedly connected to the second crushing roller 15 inside the secondary crushing box 2 through a drive shaft.

[0028] During the crushing process, the material first passes through the impact components in the primary crushing chamber 5 and is broken down into smaller pieces. Then, guided by gravity and the baffle 20, these materials fall into the secondary crushing chamber 2. The baffle 20 ensures that the material is accurately guided between the two second crushing rollers 15, preventing material from scattering or accumulating in other parts of the crushing chamber. At this point, the drive motor 6 starts working, its output end extending into the secondary crushing chamber 2, and transmitting power through the drive gear 17. The drive gear 17 meshes with both the first driven gear 16 and the second driven gear 18, forming a complete transmission system. When the drive gear 17 rotates, it drives the first driven gear 16 and the second driven gear 18 to rotate respectively, thereby driving the first crushing roller 14 and the second crushing roller 15 to perform the crushing operation. Since the first crushing roller 14 is located above and close to both sides of the second crushing roller 15, their relative movement effectively further crushes and grinds the material and prevents material bouncing, ensuring that all material is fully crushed.

[0029] Furthermore, such as Figure 1 and Figure 4As shown, the impact assembly includes two connecting rods 3, which are L-shaped. A toothed block is fixedly connected to one end of each connecting rod 3. The toothed blocks on the two connecting rods 3 are arranged opposite each other, and a drive gear 13 meshes between the toothed blocks. A connecting plate 4 is fixedly connected to the middle of one side of the primary crushing box 5. A servo motor 12 is installed at the lower end of the connecting plate 4, and the output end of the servo motor 12 is fixedly connected to the drive gear 13. The impact assembly also includes two top plates 10 located inside the primary crushing box 5. A crushing device is fixedly connected to the end face of each top plate 10 that contacts the material. Plate 9, the surface of crushing plate 9 is irregular. The top plate 10 has sliding columns 8 fixedly connected to both ends of the side face away from crushing plate 9. One end of sliding column 8 is fixedly connected to buffer spring seat 19. The end of buffer spring seat 19 away from sliding column 8 is fixedly connected to positioning column 11. The end of positioning column 11 away from buffer spring seat 19 is fixedly connected to connecting rod 3. Sliding column 8 and positioning column 11 are slidably connected to guide plate 7 and primary crushing box 5. Guide plate 7 is fixedly connected to both sides of the inner middle part of primary crushing box 5. When not started, crushing plate 9 and top plate 10 are located on the lower side of guide plate 7.

[0030] When the servo motor 12 starts, its output drives the drive gear 13, which is fixedly connected to it, to rotate. Since the toothed blocks on the two connecting rods 3 mesh with the drive gear 13, the rotation of the drive gear 13 causes the two connecting rods 3 to swing synchronously. This swinging motion of the connecting rods 3 is achieved through their L-shaped structure; one end of the connecting rod 3 meshes with the drive gear 13 via toothed blocks, and the other end is connected to the top plate 10 via a positioning pin 11. As the connecting rods 3 swing, the positioning pin 11 moves accordingly, thereby driving the top plate 10 and the crushing plate 9, which are fixedly connected to it, to reciprocate back and forth. Because the surface of the crushing plate 9 is irregular, when it comes into contact with the material, it generates a strong impact and shearing effect, thus breaking down large-volume materials into smaller pieces. Simultaneously… To enhance the stability and durability of the impact assembly, sliding columns 8 are fixedly connected to both ends of the top plate 10 on the side away from the crushing plate 9. One end of the sliding column 8 is then fixedly connected to the buffer spring seat 19. When the top plate 10 and the crushing plate 9 reciprocate back and forth, the sliding column 8 will slide in the groove of the guide plate 7 and the primary crushing box 5. The buffer spring seat 19 will buffer and dampen the movement of the top plate 10, thereby protecting the entire impact assembly from excessive impact force. When not in use, the crushing plate 9 and the top plate 10 are located on the lower side of the guide plate 7, providing sufficient space for material input and primary crushing. When the servo motor 12 is started, the entire impact assembly begins to work, breaking down large-volume materials into smaller pieces, preparing for subsequent secondary crushing operations.
