Technical Field

[0001] The utility model relates to the technical field of crushers, in particular to a hydraulic high-power roller crusher. Background Art

[0002] Hydraulic powerful roller crushers are widely used in mining, building materials, chemical industry, metallurgy and other fields to crush large pieces of materials and process them into particle sizes that meet production requirements. This type of equipment usually needs to operate under high load and complex working conditions, so its performance stability, crushing efficiency and maintenance convenience are particularly important. Traditional hydraulically driven crushers mainly use hydraulic motors to directly drive the crushing roller to rotate. Although this design is mature, there are still some technical bottlenecks.

[0003] The traditional hydraulic motor drive method may have a certain deviation in the synchronization of the crushing rollers. This is because the control accuracy and response speed of each hydraulic motor may be slightly different. Especially under high load or complex material conditions, the crushing rollers may be out of sync, resulting in reduced crushing efficiency, uneven material crushing, and even possible damage to the equipment. The hydraulic system has a large energy loss in the energy conversion process, especially under low speed and high torque conditions, and the energy efficiency performance is relatively poor. Utility Model Content

The number of the crushing components is two and they are arranged oppositely and are respectively fixed on the inner side of the crushing frame and one side of the hydraulic top cylinder. The crushing components include crushing rollers and side guide plates. A plurality of shearing tooth rings are fixedly sleeved on the surfaces of the two crushing rollers, and the shearing tooth rings on the surfaces of the two crushing rollers are arranged alternately. The surface of the side guide plate is provided with a plurality of comb teeth that are arranged alternately with the shearing tooth rings. The ends of the first shaft rod and the second shaft rod are respectively connected to the ends of the two crushing rollers through two universal couplings.

[0006] In a preferred embodiment, the present utility model can be further configured as follows: the adjusting shaft seat and the hydraulic jack are arranged horizontally, and the end of the hydraulic jack is connected to a hydraulic pump group for controlling the distance between the two crushing rollers, and the object can be extruded and crushed by the opposite movement of the two crushing rollers.

[0007] By adopting the above technical solution, the configuration of the hydraulic jack can effectively adjust the distance between the crushing rollers, ensure the uniform crushing of the material during the crushing process, and at the same time realize the adaptive adjustment of different materials by controlling the hydraulic jack, thereby improving the crushing efficiency and quality.

[0008] In a preferred embodiment, the present utility model can be further configured as follows: a feeding port located between the two crushing rollers is provided on the top surface of the crushing frame, and a sensor group is provided inside the feeding port. The sensor is an ultrasonic density sensor for detecting the density of the input object.

[0009] By adopting the above technical solution, the ultrasonic density sensor can real-time detect the density of the input material and adjust the distance between the crushing rollers according to the density data, thereby further optimizing the crushing effect and avoiding the uneven crushing phenomenon caused by the density difference of the material.

[0010] In a preferred embodiment, the present utility model can be further configured as follows: the surface of the driving box is connected to a hydraulic pump group through a liquid passing hole, and the input end of the hydraulic pump group is electrically connected to a controller, and the input end of the controller is electrically connected to the input end of the ultrasonic density sensor.

[0012] In a preferred embodiment, the present utility model can be further configured as follows: the shear tooth rings on the surface of the crushing rollers are arranged at intervals in turn, and the gap between adjacent shear tooth rings is equal to the thickness of the shear tooth rings, and the shear tooth rings on the surfaces of the two crushing rollers are meshed with each other.

[0013] By adopting the above technical solution, the interval arrangement and meshing design of the shear tooth rings can not only enhance the crushing effect of the material, but also reduce the situation of material blockage and ensure the continuity and stability of the crushing process.

[0027] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail in combination with specific implementation methods and with reference to the accompanying drawings. The utility model relates to a hydraulic high-power roller crusher, which is widely used in the fields of mining, building materials, chemical industry and metallurgy for efficient crushing of bulk materials. Figures 1 to 5 The specific structure and operation of the crusher are described in detail.

[0028] like Figure 1 As shown, the hydraulic high-power roller crusher of the utility model mainly includes the following parts: a crushing frame 100, a crushing assembly 200, a driving assembly 300, and a universal coupling 400.

[0029] The crushing frame 100 is the skeleton of the entire crusher, carrying and supporting the crushing assembly 200 and the driving assembly 300. The crushing frame is made of high-strength steel to ensure its stability under high load and complex working conditions. The design of the crushing frame allows the internal components to be firmly installed and provides space for adjustment and maintenance. An adjustment shaft seat 110 is provided on the inner side of the crushing frame 100, and the adjustment shaft seat 110 can move laterally along the slide rail of the crushing frame 100. This design allows the adjustment shaft seat to accurately adjust the spacing between the crushing rollers 210 to meet the crushing requirements of different materials.

[0030] The adjustment mechanism consists of an adjustment shaft seat 110 and a hydraulic top cylinder 120. The adjustment shaft seat 110 is installed on the inner side of the crushing frame 100 and is fixedly connected to one end of the hydraulic top cylinder 120. The hydraulic top cylinder 120 is installed in the horizontal direction and connected to the hydraulic pump group, and the lateral movement of the adjustment shaft seat 110 can be controlled by the hydraulic system. By adjusting the pressure of the hydraulic top cylinder, the spacing between the two crushing rollers 210 can be accurately controlled, thereby adjusting the crushing roller's squeezing force on the material. This design not only improves the crushing accuracy, but also can quickly adjust the equipment to adapt to different operating conditions, greatly enhancing the flexibility and adaptability of the crusher.

[0031] like Figure 2 and Figure 4 As shown, the crushing assembly 200 includes two crushing rollers 210 arranged opposite to each other, and a plurality of shearing tooth rings 230 are fixedly mounted on the outer surface of each crushing roller. These shearing tooth rings 230 are arranged in a staggered manner to ensure that the material can be evenly sheared between the crushing rollers. The two ends of each crushing roller 210 are respectively connected to the first shaft 311 and the second shaft 312 in the driving assembly 300 through a universal coupling 400 to ensure that the crushing rollers can rotate synchronously.

[0032] The crushing roller 210 is the main working component, which is made of high-hardness wear-resistant materials to meet the crushing requirements of hard materials such as ores and coals. The shear tooth ring 230 is designed in a ring shape and fixed on the crushing roller at a certain interval. There is a gap between adjacent shear tooth rings, and the size of the gap is equal to the thickness of the shear tooth ring. This structure ensures that the material can be fully crushed during the shearing process without large particles remaining.

[0033] In addition, the crushing assembly also includes side guide plates 220 and comb teeth 240. The side guide plates 220 are installed on the sides of the crushing roller to guide the material flow towards the crushing roller 210. The comb teeth 240 are arranged staggered with the shear tooth rings 230 to further refine the material during the crushing process. Both the side guide plates and the comb teeth are designed to be detachable, facilitating regular inspection and replacement, and reducing the difficulty and cost of equipment maintenance.

[0034] As Figure 3 and Figure 5 shown, the drive assembly 300 is the core power part of the crusher, including a drive box 310, a first shaft 311, a second shaft 312, and an impeller 320. The drive box 310 is installed outside the crushing frame and is connected to the crushing roller 210 through a universal coupling 400. Inside the drive box 310, the first shaft 311 and the second shaft 312 are arranged in parallel, both passing through both sides of the drive box and meshing and driving each other through the impeller 320.

[0035] The impeller 320 is installed outside the first shaft 311 and the second shaft 312 and has a multi-blade structure. These blades are treated with wear resistance, increasing the durability and stability of the drive assembly. The design of the impeller ensures the smooth rotation of the crushing roller 210 while reducing friction and energy loss. There are also liquid passing holes 313 on the surface of the drive box 310, located on the midline of the first shaft and the second shaft and penetrating the drive box, for the circulation of hydraulic fluid to ensure the normal operation of the drive assembly.

[0036] The universal coupling 400 is installed between the drive box 310 and the crushing roller 210, playing a role in transmitting power and buffering torque. Its design can adapt to the angular changes between different axes, reducing the losses caused by assembly errors or deviations during operation, thereby protecting the crushing roller and the drive assembly and extending the service life of the equipment.

[0037] Working principle and usage process

[0038] Equipment startup: Start the hydraulic system of the crusher, and the first shaft 311 and the second shaft 312 in the drive assembly 300 start to rotate, driving the impeller 320 and the crushing roller 210 to rotate synchronously.

[0039] Material feeding: The large pieces of material to be processed are fed into the crusher through the feeding port at the top of the crushing frame 100. The material enters between the crushing rollers 210 under the action of gravity. The ultrasonic density sensor continuously detects the density of the fed material and transmits the data to the controller.

[0040] Crushing process: The controller adjusts the pressure of the hydraulic jack cylinder 120 according to the detection data of the sensor to precisely control the spacing between the crushing rollers 210. The material is subjected to the shearing action of the shear tooth ring 230 and the squeezing action of the crushing rollers 210 between the crushing rollers, and is gradually crushed into smaller particles. At the same time, the side guide plate 220 guides the material to move towards the crushing rollers, and the comb teeth 240 further refine the material to ensure uniform crushing of the material.

[0041] Discharging process: The crushed material is discharged through the discharging port under the crushing rollers. The entire crushing process is automatically monitored by the controller to ensure the crushing efficiency and uniformity, and to prevent equipment overload.

[0042] Equipment shutdown: After the crushing operation is completed, the operation of the drive assembly is stopped, and the crushing rollers stop rotating. The hydraulic system is closed, and the equipment enters the shutdown state.

[0043] Maintenance and servicing: Regularly check and maintain the wear conditions of the crushing rollers, shear tooth rings, side guide plates and comb teeth, and replace them as needed. The impeller has been treated with wear resistance, and usually has a longer maintenance cycle, but still needs to be regularly inspected to ensure its good condition.

[0044] Through the above detailed description, the hydraulic powerful roller crusher of the present utility model can effectively cope with high loads and complex working conditions, has remarkable crushing efficiency and a long service life, and is convenient for maintenance and has strong adaptability.
