Description

Technical Field

[0001] This utility model relates to the field of high-speed multi-cylinder cone crusher technology, specifically a high-speed multi-cylinder cone crusher with a large crushing ratio. Background Technology

[0002] High-speed multi-cylinder cone crushers are widely used in mining, building aggregate production, and chemical raw material processing due to their high efficiency and stable performance. Traditional high-speed multi-cylinder cone crushers primarily achieve material crushing by applying compressive and bending forces to the material entering the crushing chamber through the eccentric oscillation of the moving cone within the fixed cone. The multi-cylinder hydraulic system provides stable crushing force, effectively improving the equipment's processing capacity and reliability.

[0003] However, with the increasing market demands for finer particle sizes in crushed products, such as in high-end construction sand and deep mineral processing, materials need to be crushed to finer sizes to meet subsequent processing requirements. Existing high-speed multi-cylinder cone crushers rely solely on a single crushing process, resulting in a limited crushing ratio. This leads to uneven particle size distribution and a low proportion of fine particles, making it difficult to meet the requirements of refined production. While some technologies attempt to improve the crushing ratio by adjusting the crushing chamber shape or increasing the crushing force, the effects are limited and may increase energy consumption and reduce equipment lifespan. Furthermore, existing technologies lack dedicated structural designs for secondary crushing, failing to fully utilize the material's movement characteristics within the crushing chamber to further refine the particles.

[0004] Therefore, a high-speed multi-cylinder cone crusher with a large crushing ratio is needed to solve this problem. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a high-speed multi-cylinder cone crusher with a large crushing ratio.

[0020] 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.

[0021] like Figures 1 to 4As shown, this utility model provides a high-speed multi-cylinder cone crusher with a large crushing ratio, including a discharge port 1 of the main body of the high-speed multi-cylinder cone crusher, a secondary crushing box 2 connected to the bottom of the discharge port 1, a rotating groove 3 symmetrically opened on the top of the inner wall of the secondary crushing box 2, a jaw plate 4 rotatably connected inside the rotating groove 3, and the jaw plate 4 rotatably connected to the secondary crushing box 2, hydraulic telescopic rods 5 symmetrically fixedly connected on both sides of the secondary crushing box 2, the output end of the hydraulic telescopic rod 5 passing through the secondary crushing box 2 and fixedly connected to a hinge 6, a slider 7 rotatably connected inside the hinge 6, a sliding groove 8 opened on the rear side of the jaw plate 4, and the sliding groove 8 slidably connected to the slider 7, a number of uniformly arranged crushing strips 9 fixedly connected to the surface of the jaw plate 4, a crushing roller 10 rotatably connected inside the secondary crushing box 2, a number of uniformly arranged crushing rings 11 fixedly connected to the surface of the crushing roller 10, a number of uniformly arranged ring-shaped crushing blocks 12 fixedly connected to the surface of the crushing rings 11, and a discharge hopper connected to the bottom of the secondary crushing box 2.

[0022] The aforementioned high-speed multi-cylinder cone crusher is based on existing mature technology. Similar to a general multi-cylinder hydraulic cone crusher, the motor drives the horizontal shaft through a transmission device. The horizontal shaft drives the eccentric sleeve to rotate through gear transmission. The eccentric sleeve drives the main shaft to make the moving cone part swing. Between the eccentrically swinging moving cone liner and the fixed cone liner, the material is continuously squeezed and bent and crushed. The crushed material is discharged from the discharge port 1 of the crusher body.

[0023] refer to Figure 4 The inner wall of the secondary crushing box 2 is symmetrically provided with auxiliary blocks 13 about the hydraulic telescopic rod 5. The other end of the auxiliary block 13 is hinged to a buffer 14, and the other end of the buffer 14 is hinged to the jaw plate 4.

[0024] As a technical optimization of this utility model, the auxiliary block 13 and the buffer 14 can play an auxiliary support and buffer role when the jaw plate 4 swings, reduce the shaking of the jaw plate 4, improve the stability and reliability of crushing, and extend the service life of the equipment.

[0025] refer to Figure 3 and Figure 4 A buffer spring 15 is sleeved on the surface of the output end of the hydraulic telescopic rod 5, and the buffer spring 15 is located on the outside of the hinge 6.

[0026] As a technical optimization of this utility model, by setting the buffer spring 15, the impact force at the output end of the hydraulic telescopic rod 5 can be further buffered, protecting the hydraulic telescopic rod 5 and the hinge 6 and other components, while making the movement of the jaw plate 4 more gentle and improving the crushing effect.

[0027] refer to Figure 1 and Figure 2A reducer 16 is fixedly connected to the outside of the secondary crushing box 2, and the output end of the reducer 16 is fixedly connected to the crushing roller 10. A servo motor 17 is fixedly connected to the input end of the reducer 16, and the servo motor 17 is fixedly connected to the reducer 16.

[0028] As a technical optimization of this utility model, by setting the crushing roller 10 to be driven by the servo motor 17 and the reducer 16, the rotation speed of the crushing roller 10 can be precisely controlled to adapt to the crushing requirements of different materials and improve crushing efficiency and quality.

[0029] refer to Figure 4 The groove wall of the slide 8 is provided with a limiting groove 18, and the other end of the slider 7 is fixedly connected to a limiting block 19, and the limiting block 19 is slidably connected to the limiting groove 18.

[0030] As a technical optimization of this utility model, by setting the limiting groove 18 and the limiting block 19, the sliding range of the slider 7 in the sliding groove 8 can be limited, ensuring the swing angle and position accuracy of the jaw plate 4, making the crushing process more stable and controllable.

[0031] refer to Figure 2 and Figure 3 The maximum deflection angle of the jaw plate 4 does not contact the outer side of the crushing block 12, and several crushing rings 11 are alternately arranged with several crushing strips 9.

[0032] As a technical optimization of this utility model, by setting the maximum deflection angle of the jaw plate 4 to not contact the outer side of the crushing block 12, collision damage between the two can be avoided, ensuring the normal operation of the equipment. By setting the crushing ring 11 and the crushing bar 9 alternately, the material can be subjected to more sufficient compression, shearing and grinding during the crushing process, improving the crushing effect and uniformity.

[0033] The working principle and usage process of this utility model are as follows: When using this high-speed multi-cylinder cone crusher, first install the high-speed multi-cylinder cone crusher on an external support frame of appropriate height. Then check whether the main body of the high-speed multi-cylinder cone crusher and the secondary crushing box 2 are in good condition, including whether the connections of components such as the hydraulic telescopic rod 5, jaw plate 4, and crushing roller 10 are secure, whether the lubrication and hydraulic systems are normal, and whether the electrical system is connected and fault-free. Start the servo motor 17 to put the crushing roller 10 in standby rotation state. At the same time, start the motor of the main body of the high-speed multi-cylinder cone crusher to start it running. Then, the material enters from the feed port of the main body of the high-speed multi-cylinder cone crusher and passes through the moving cone inside the crusher body. After being crushed by the fixed cone, the material is discharged from the discharge port 1 and enters the secondary crushing box 2. The material entering the secondary crushing box 2 is first crushed by the jaw plate 4. The hydraulic telescopic rod 5 extends or shortens in time according to the set parameters or the crushing condition of the material, causing the jaw plate 4 to swing. At the same time, the rotating crushing roller 10 further crushes the material after it has been crushed by the jaw plate 4. Under the action of the crushing bar 9, crushing ring 11 and crushing block 12, the material is crushed into smaller particles. The material after secondary crushing is discharged from the discharge hopper at the bottom of the secondary crushing box 2, completing the entire crushing process. This adapts to different materials and crushing requirements, thereby improving product quality and production efficiency, and meeting the industry's urgent need for fine crushing.
