[0002] The crushing chamber is the core working area of ​​the crusher. Its main function is to crush the incoming materials. The design and construction of the crushing chamber directly affect the equipment's working efficiency, product particle size distribution, and service life.

[0003] In existing technologies, traditional crusher chambers are not equipped with specially designed disassembly mechanisms. Replacing liners often requires more time and complicated procedures to remove old liners and install new ones, which increases maintenance difficulty and workload. At the same time, if severely worn liners are not replaced in time, the inner wall of the crushing chamber and other key components may wear out faster, thus shortening the overall service life of the equipment. Utility Model Content

[0004] The purpose of this invention is to provide a crusher chamber suitable for fine-particle feeding, which aims to solve the problem that traditional crusher chambers in the prior art are not equipped with a specially designed disassembly mechanism, and that replacing the liner often requires more time and complicated operation steps to remove the old liner and install the new liner, thereby increasing the maintenance difficulty and workload.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A crusher chamber suitable for fine-particle feeding includes:

[0007] The rupture chamber;

[0008] Two liner plates are respectively disposed on the inner walls of the two sides of the crushing chamber;

[0009] The quick-release mechanism is located in the crushing chamber and the liner plate. The quick-release mechanism includes a first lock cylinder, a second lock cylinder and a rotating locking pin. The two first lock cylinders are fixedly connected in the crushing chamber, the two second lock cylinders are fixedly connected in the liner plate, and the two rotating locking pins are slidably connected in the multiple first lock cylinders and second lock cylinders.

[0010] A locking mechanism is provided within the quick-release mechanism.

[0011] As a preferred embodiment of the present invention, the locking mechanism includes a spring returner, a threaded groove, and a threaded locking rod. The two spring returners are fixedly connected to the crushing chamber. The two spring returners are located on the rear side of the multiple first lock cylinders and the rotating locking pin. The two threaded grooves are opened through the multiple first lock cylinders and the second lock cylinder. The two threaded locking rods are threadedly rotatably connected to the two threaded grooves.

[0012] In a preferred embodiment of this utility model, a hydraulic piston is fixedly connected inside the crushing chamber, and an eccentric bushing is fixedly connected to the upper end of the hydraulic piston.

[0013] In a preferred embodiment of this utility model, the upper end of the eccentric bushing is rotatably connected to a rotating seat, and the upper end of the rotating seat is fixedly connected to a moving cone.

[0014] In a preferred embodiment of this utility model, a driver is fixedly connected to the upper end of the crushing chamber, and a connecting rod is fixedly connected to the lower end of the driver. The lower side of the connecting rod is connected to the upper surface of the moving cone.

[0015] As a preferred embodiment of this utility model, two discharge ports are provided through the crushing chamber.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] I. In this solution, the present invention facilitates quick replacement of the liner after wear, thereby reducing downtime and improving equipment utilization. At the same time, by using special tools or optimizing the design, the disassembly and installation process can be simplified, reducing the requirements for professional skills.

[0018] II. In this solution, the locking mechanism consists of a spring return mechanism, a threaded groove, and a threaded locking rod. This structure is integrated inside the crushing chamber, located behind the first lock cylinder and the rotating locking pin of the quick-release mechanism. Two spring return mechanisms are fixedly installed on the inner wall of the crushing chamber, corresponding to the linkage area between the first and second lock cylinders. They provide elastic restoring force, pushing the rotating locking pin backward to disengage it from the locked state when the liner is removed. The threaded grooves penetrate multiple first and second lock cylinders, serving as the mating channels for the threaded locking rods. The two threaded locking rods are screwed into their corresponding threaded grooves and rotated to achieve axial displacement, thereby controlling the connection and separation between the lock cylinders. When the liner needs to be locked, the threaded locking rod is rotated to advance it forward and press against the lock cylinder structure, forming a stable mechanical connection. When disassembly is required, the threaded locking rod is rotated in the opposite direction to release the pressure between the lock cylinders. Then, the spring force of the spring return mechanism pushes out the rotating locking pin, completing the unlocking action. This linkage mechanism not only enhances the stability of the quick-release mechanism but also improves the safety and convenience of operation, making the liner replacement process more efficient and reliable.

[0025] 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.

[0026] Example

[0027] Please see Figures 1-4 The present invention provides the following technical solution:

[0028] A crusher chamber suitable for fine-particle feeding includes:

[0029] Broken chamber 1;

[0030] Two liner plates 2 are respectively installed on the inner walls of both sides of the crushing chamber 1;

[0031] The quick-release mechanism is located in the crushing chamber 1 and the liner plate 2. The quick-release mechanism includes a first lock cylinder 3, a second lock cylinder 4 and a rotating locking pin 5. The two first lock cylinders 3 are fixedly connected in the crushing chamber 1, the two second lock cylinders 4 are fixedly connected in the liner plate 2, and the two rotating locking pins 5 are slidably connected in the multiple first lock cylinders 3 and second lock cylinders 4.

[0032] The locking mechanism is located within the quick-release mechanism.

[0033] In a specific embodiment of this utility model, the crushing chamber 1 serves as the main structure of the entire device, used to accommodate the moving cone 12 and materials during crushing operations, and to withstand continuous impact and wear. Liners 2 are installed on both inner walls of the chamber, and these liner plates 2 are made of wear-resistant material to directly withstand material impact and friction, protecting the crushing chamber 1 from damage and improving crushing efficiency. A quick-release mechanism is provided between the liner plate 2 and the crushing chamber 1. This mechanism consists of a first locking core 3, a second locking core 4, and a rotating locking pin 5. The first locking core 3 is embedded and fixed inside the crushing chamber 1, while the second locking core 4 is embedded inside the liner plate 2. The two are mechanically locked by the rotating locking pin 5, which is slidably connected through the liner plate 2. When the liner plate 2 needs to be replaced or maintained, simply rotate and pull out the rotating locking pin 5 to release the fixing constraint on the liner plate 2, thereby achieving quick disassembly. This linkage structure, through the cooperation between the locking core and the locking pin, ensures the stable installation of the liner plate 2 while avoiding the complex disassembly and assembly problems, time-consuming and labor-intensive problems caused by traditional bolt fixing methods, significantly improving the maintainability and operating efficiency of the equipment.

[0034] Please refer to the details. Figures 1-4 The locking mechanism includes a spring returner 6, a threaded groove 7, and a threaded locking rod 8. Both spring returners 6 are fixedly connected to the crushing chamber 1. Both spring returners 6 are located on the rear side of multiple first lock cylinders 3 and rotating locking pins 5. Both threaded grooves 7 are opened through multiple first lock cylinders 3 and second lock cylinders 4. Both threaded locking rods 8 are threadedly rotatably connected to the two threaded grooves 7.

[0035] In this embodiment, the locking mechanism consists of a spring-loaded spring 6, a threaded groove 7, and a threaded locking rod 8. This structure is integrated inside the crushing chamber 1, located behind the first lock cylinder 3 and the rotating locking pin 5 of the quick-release mechanism. Two spring-loaded springs 6 are fixedly installed on the inner wall of the crushing chamber 1, their positions corresponding to the linkage area between the first lock cylinder 3 and the second lock cylinder 4. They provide elastic restoring force, pushing the rotating locking pin 5 backward when the liner 2 is removed, thus disengaging it from the locked state. The threaded groove 7 penetrates multiple first lock cylinders 3 and second lock cylinders 4, serving as the mating channel for the threaded locking rod 8. Each threaded locking rod 8 is screwed into its corresponding threaded groove 7 and rotates to achieve axial displacement, thereby controlling the connection and separation between the lock cylinders. When the liner 2 needs to be locked, the threaded locking rod 8 is rotated to advance it forward and press the lock cylinder structure, forming a stable mechanical connection. When disassembly is required, the threaded locking rod 8 is rotated in the opposite direction to release the pressure between the lock cylinders. Then, with the help of the spring force of the spring return device 6, the rotating locking pin 5 is pushed out to complete the unlocking action. This linkage mechanism not only enhances the stability of the quick-release mechanism, but also improves the safety and convenience of operation, making the replacement process of the liner 2 more efficient and reliable.

[0036] Please refer to the details. Figures 1-4A hydraulic piston 9 is fixedly connected inside the crushing chamber 1, and an eccentric bushing 10 is fixedly connected to the upper end of the hydraulic piston 9.

[0037] In this embodiment, a hydraulic piston 9 is fixedly connected inside the crushing chamber 1, and its upper end is further rigidly connected to the eccentric bushing 10, forming the core linkage structure in the cone crusher for adjusting the moving cone 12 and protecting against overload. In actual operation, the hydraulic piston 9 achieves vertical displacement through changes in hydraulic oil pressure. This displacement is directly transmitted to the eccentric bushing 10 connected to it, thereby driving the rotating seat 11 and the moving cone 12 carried by the eccentric bushing 10 to move vertically. This structural design replaces the traditional spring-type or mechanical screw-type adjustment method. The hydraulic drive has higher response speed and control precision. From the perspective of existing technology, in early cone crushers, spring devices or manual screws were usually used to adjust the discharge opening. While this method is suitable for handling small loads and overload conditions, it suffers from drawbacks such as poor adjustment accuracy, delayed response, and complex operation. With the development of hydraulic technology, more and more crushing equipment is beginning to introduce hydraulic pistons 9 as actuators, which are used in conjunction with eccentric bushings 10. This not only improves the dynamic adjustment capability during the crushing process, but also allows for rapid pressure release when encountering uncrushable foreign objects, preventing equipment damage. The linkage mechanism between hydraulic pistons 9 and eccentric bushings 10 enables the crusher to automatically adapt to changes in material particle size, while improving the stability and efficiency under fine feeding conditions, reducing the frequency of manual intervention, and enhancing the automation level and continuous operation capability of the equipment. It is a key component combination for achieving intelligent adjustment and safety protection in modern high-efficiency crushing systems.

[0038] Please refer to the details. Figures 1-4 The upper end of the eccentric bushing 10 is rotatably connected to a rotating seat 11, and the upper end of the rotating seat 11 is fixedly connected to a moving cone 12.

[0039] In this embodiment, the upper end of the eccentric bushing 10 is connected to the rotating seat 11 by a rotatable connection, enabling it to rotate around the central axis during operation. The upper end of the rotating seat 11 is fixedly connected to the moving cone 12, thereby converting the eccentric rotation of the eccentric bushing 10 into the eccentric rotation trajectory of the moving cone 12 in the crushing chamber 1. This linkage structure is based on the principle of the eccentric mechanism in the traditional cone crusher. That is, through the assembly relationship between the eccentric hole of the eccentric bushing 10 and the main shaft, the eccentric bushing 10 is rotated under the drive of the drive device, and the rotating seat 11 and the moving cone 12 are continuously oscillating along the set trajectory to realize the continuous squeezing, shearing and crushing of the material entering the crushing chamber 1.

[0040] Please refer to the details. Figures 1-4 The upper end of the crushing chamber 1 is fixedly connected to a driver 13, and the lower end of the driver 13 is fixedly connected to a connecting rod 14. The lower side of the connecting rod 14 is connected to the upper surface of the moving cone 12.

[0041] In this embodiment: A driver 13 is fixedly connected to the upper end of the crushing chamber 1, and the lower end of the driver 13 is fixedly connected to the connecting rod 14. A moving cone 12 is provided on the lower side of the connecting rod 14, forming a mechanical linkage structure for transmitting driving power to the moving cone 12. During operation, the driver 13 provides power through electricity or hydraulic means, driving the connecting rod 14 to rotate or reciprocate, thereby transmitting power to the moving cone 12 connected to it, so that it eccentrically swings or rotates along a set trajectory in the crushing chamber 1, thereby realizing continuous crushing of fine materials.

[0042] Please refer to the details. Figures 1-4 Two discharge ports 15 are opened through the crushing chamber 1.

[0043] In this embodiment, two discharge ports 15 are opened through the inside of the crushing chamber 1. The discharge ports 15 serve as channels for material discharge after crushing and directly connect the inside of the crushing chamber 1 with the external conveying system. During the operation of the equipment, after being squeezed and sheared by the moving cone 12 and the fixed cone, the fine particles that meet the particle size requirements are evenly discharged from the two symmetrically arranged discharge ports 15 by gravity, thereby realizing continuous crushing and discharge operations.

[0044] The working principle and usage process of this utility model are as follows: First, fine particles are fed into the upper part of the crushing chamber 1. After entering, the material is crushed by the squeezing and shearing action between the moving cone 12 and the fixed cone. The driver 13 provides power and drives the eccentric bushing 10 to rotate through the connecting rod 14. The eccentric bushing 10 drives the moving cone 12 to swing eccentrically through the rotating seat 11, realizing continuous crushing action. The crushed material is discharged through two symmetrically opened discharge ports 15 inside the crushing chamber 1 under the action of gravity, ensuring smooth discharge and uniform distribution. When it is necessary to replace the worn liner 2, the operator rotates the threaded locking rod 8 to remove it from the threaded groove 7, releasing the lock on the first lock core 3 and the second lock core 4. The rear spring mechanism 6 pushes the rotating locking pin 5 to slide backward and disengage from the lock core structure, thereby releasing the fixed state between the liner 2 and the crushing chamber 1, thus achieving quick disassembly. When installing a new liner 2, the operation is carried out in the reverse order. The rotating locking pin 5 is inserted into the first lock core 3 and the second lock core 4, and then re-locked by the threaded locking rod 8 to complete the fixing of the liner 2. During operation, the hydraulic piston 9 is used to adjust the position of the moving cone 12 to adapt to different working conditions and realize the overload protection function. This utility model facilitates quick replacement of the liner 2 after wear, thereby reducing downtime and improving equipment utilization. At the same time, by using special tools or optimizing the design, the disassembly and installation process can be simplified, reducing the requirements for professional skills.

[0045] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
