Technical Field
[0001] This utility model relates to the technical field of ring hammer crushers, and in particular to a ring hammer crusher that facilitates the replacement of easily worn parts. Background Technology
[0002] Hammer crushers are equipment that crush materials by impact. They come in single-rotor and double-rotor versions. Hammer crushers are suitable for crushing medium-hard materials such as limestone, slag, coke, and coal in industries such as cement, chemical, power, and metallurgy.
[0003] In practical applications, since the breaker hammer and the turntable are fixedly installed as a whole, when the crushing roller wears out after long-term use and needs to be disassembled and replaced, the turntable and the crushing roller must be removed and replaced as a whole, which is time-consuming and laborious, and affects the efficiency of the crusher. Utility Model Content
[0004] To address the problem of cumbersome disassembly in existing technologies, this invention proposes a ring hammer crusher that facilitates the replacement of easily worn parts, enabling rapid disassembly of the crushing rollers as a whole.
[0005] A ring hammer crusher with easy replacement of wear parts includes an electric assembly, a support frame is fixedly connected to the bottom of the electric assembly, and a crushing roller is provided at the front end of the electric assembly.
[0006] The surface of the crushing roller is provided with a disassembly device, which includes a U-shaped clamping plate. A connecting plate is provided on the rear end surface of the U-shaped clamping plate. A slide rail is slidably connected to the bottom of the U-shaped clamping plate. A U-shaped slider is slidably connected to the bottom inner wall of the slide rail. A slide groove is slidably connected to the bottom of the U-shaped slider. A protective shell is fixedly connected to the bottom center surface of the U-shaped slider. An electric telescopic rod is fixedly connected to the bottom inside of the protective shell. A caster wheel is fixedly connected to the bottom of the electric telescopic rod.
[0007] Furthermore, the surface of the electric telescopic rod is provided with a limiting device, the limiting device including a threaded rod, the surface of the threaded rod penetrating through the output end of the electric telescopic rod, one end of the threaded rod is threadedly connected to a square plate one, the other end of the threaded rod is threadedly connected to a square plate two, the top of the square plate one is hinged with a slot, the surface of the slot is fixedly connected to the right surface of the protective shell, and the top of the square plate two is fixedly connected to the left surface of the protective shell.
[0008] Furthermore, the rear end of the connecting plate is fixedly connected to the front end surface of the electric component, and the surface of the crushing roller is rotatably connected to the inner wall of the connecting plate. The rear end of the connecting plate is fixedly connected to the front end surface of the electric component, ensuring stability and integrity. The surface of the crushing roller is rotatably connected to the inner wall of the connecting plate.
[0009] Furthermore, a baffle is fixedly connected to the inner wall of the opening of the U-shaped clamp, and a pull ring is fixedly connected to the front surface of the protective shell. These features, used to block or protect specific areas and prevent the crushing roller from detaching from the interior of the U-shaped clamp during movement, provide additional safety or protection and may enhance the overall structural stability. This is particularly important in applications subject to impact or vibration, as it can disperse or absorb some of the external force, improving the system's durability.
[0010] Furthermore, the surface of the square plate is provided with a handle, and the surface of the handle is fixedly connected to the surface of the threaded rod. The presence of the handle makes the square plate easier to carry and move, and the square plate can be easily lifted or carried using the handle. The design of connecting to the threaded rod can increase the sturdiness of the handle, ensuring that the handle is firmly connected to the square plate, preventing the handle from loosening or falling off during use, and improving the stability of the entire system.
[0011] Furthermore, a warning light is fixedly connected to the surface of the second square plate. The surface of the warning light penetrates and adheres to the surface of the threaded rod. The brightness and color of the warning light can be conveyed to the user through the surface penetrating the threaded rod, which can enhance the visibility of the warning signal and reduce the possibility of shaking or movement during use.
[0012] Unlike existing technologies, the beneficial effects of this application are as follows:
[0013] (1) The ring hammer crusher, which facilitates the replacement of wear parts, extends the electric telescopic rod by starting the controller. At the same time, it drives the U-shaped slider at the top to slide forward in the slide groove on the support frame. Simultaneously, it drives the U-shaped card plate of the slide rail box at the top to move synchronously. The other end of the crushing roller will be pulled out of the electric assembly. At the same time, the baffle at the opening of the U-shaped card plate helps to support the crushing roller during movement, so as to help the equipment to be disassembled as a whole.
[0014] (2) The ring hammer crusher, which is easy to replace the wear parts, rotates the square plate in the slot to rotate the handle on its surface parallel to the electric telescopic rod, and drives the threaded rod to rotate. The threaded rod can only move towards the square plate and penetrates the surface of the electric telescopic rod. At the same time, the warning light in the square plate illuminates when the threaded rod contacts the square plate, so as to increase the secondary support force when the equipment moves.

[0030] Example 1
[0031] Please see Figures 1-4 As shown in the figure, a ring hammer crusher that facilitates the replacement of wear parts includes an electric component 100, a support frame 200 fixedly connected to the bottom of the electric component 100, and a crushing roller 300 provided at the front end of the electric component 100.
[0032] Firstly, a disassembly device 400 is provided on the surface of the crushing roller 300. The disassembly device 400 includes a U-shaped clamping plate 401. A connecting plate 402 is provided on the rear end surface of the U-shaped clamping plate 401. The rear end of the connecting plate 402 is fixedly connected to the front end surface of the electric component 100. The surface of the crushing roller 300 is rotatably connected to the inner wall of the connecting plate 402. The rear end of the connecting plate 402 is fixedly connected to the front end surface of the electric component 100, which provides stability and a sense of unity. The surface of the crushing roller 300 is rotatably connected to the inner wall of the connecting plate 402. A slide rail 403 is slidably connected to the bottom of the U-shaped clamping plate 401. A baffle 410 is fixedly connected to the inner wall of the opening of the U-shaped clamping plate 401. A pull ring 409 is fixedly connected to the front end surface of the protective shell 406. By blocking or protecting specific areas, the crushing roller 300 is prevented from detaching from the inside of the U-shaped clamping plate during movement, providing additional safety or protection functions, which may enhance the stability of the overall structure. Applications subject to impact or vibration during use may be important because it can disperse or absorb some of the external force and improve the durability of the system. A U-shaped slider 404 is slidably connected to the bottom inner wall of the slide rail 403. A slide groove 405 is slidably connected to the bottom of the U-shaped slider 404. A protective shell 406 is fixedly connected to the bottom center surface of the U-shaped slider 404. An electric telescopic rod 407 is fixedly connected to the bottom inside of the protective shell 406. A caster wheel 408 is fixedly connected to the bottom of the electric telescopic rod 407.
[0033] When replacing the crushing roller 300 in the equipment, first use a wrench or similar tool to separate the U-shaped clamping plate 401 and the connecting plate 402. Then, activate the electric telescopic rod 407 via the controller to extend it, bringing the end caster wheel 408 into contact with the ground. Simultaneously, pull the pull ring 409 at the front of the protective shell 406, which in turn causes the top U-shaped slider 404 to slide forward in the groove 405 on the support frame 200. This also causes the top slide rail 403 and the U-shaped clamping plate 401 to move synchronously. It is explained here that when the U-shaped clamp 401 moves, it drives the crushing roller 300 connected to its inner wall to move. The other end of the crushing roller 300 will be pulled out of the electric assembly 100. At the same time, the baffle 410 at the opening of the U-shaped clamp 401 helps to support the crushing roller 300 during movement and prevent it from collapsing. After being pulled to the designated position, the U-shaped clamp 401 and the slide rail 403 are separated from the U-shaped slider 404 by personnel using tools to help personnel quickly disassemble the crushing roller 300 as a whole.
[0034] To ensure stable and safe movement of the equipment during disassembly, please refer to [link / reference needed]. Figures 1-4As shown in the figure, a limiting device 500 is provided on the surface of the electric telescopic rod 407. The limiting device 500 includes a threaded rod 504, the surface of which penetrates the output end of the electric telescopic rod 407.

A handle 503 is provided on the surface of the square plate 502, and the surface of the handle 503 is fixedly connected to the surface of the threaded rod 504. The presence of the handle 503 makes the square plate 502 easier to carry and move, allowing for easy lifting or carrying of the square plate. The design of connecting to the threaded rod 504 increases the handle's sturdiness, ensuring that the handle 503 is securely connected to the square plate 502 and preventing the handle from being used improperly. During the process, loosening or detachment occurs, improving the stability of the entire system. The other end of the threaded rod 504 is threadedly connected to a square plate 505. A warning light 506 is fixedly connected to the surface of the square plate 505. The surface of the warning light 506 penetrates and adheres to the surface of the threaded rod 504. The brightness and color of the warning light 506 can be conveyed to the user through the surface of the threaded rod 504, which can enhance the visibility of the warning signal and reduce the possibility of shaking or moving during use. The top of the square plate 502 is hinged to a slot 501. The surface of the slot 501 is fixedly connected to the right surface of the protective shell 406. The top of the square plate 505 is fixedly connected to the left surface of the protective shell 406.
[0035] In use, before the operator pulls the equipment, the square plate 502 in the slot 501 is rotated to align with the electric telescopic rod 407. Then, the operator rotates the handle 503 on its surface, causing the threaded rod 504 to rotate. The threaded rod 504 can only move towards the square plate 505 and penetrates the surface of the electric telescopic rod 407 to help stabilize the electric telescopic rod 407 after it extends. After the threaded rod 407 contacts the warning light 506 in the square plate 505, the warning light 506 illuminates to remind the operator that the secondary support of the electric telescopic rod 407 has been secured.
