Description

Technical Field

[0001] This utility model relates to the field of crusher technology, specifically to replaceable hammers for crusher rotors. Background Technology

[0002] Crushing machinery used in the processing of metallic and non-metallic minerals can crush the mined raw ore into small particles through compression and bending. When the material enters the action zone of the hammer, it is first crushed by the impact of the hammer. This process is repeated until it is crushed into the required particle size and discharged from the machine.

[0003] Among the existing technologies, the authorized announcement number CN222658796U proposes a crusher hammer head that is easy to install, including a hammer handle, a hammer head body that fits against the bottom of the hammer handle, a first slot at the middle position of the bottom of the hammer handle, and a second slot at the middle position of the top of the hammer head body. The first slot and the second slot are symmetrical to each other, and both the first slot and the second slot are convex in shape.

[0004] In existing technologies, the entire rotor body needs to be disassembled before quick assembly and disassembly can be performed. The hammers cannot be disassembled and assembled quickly on their own, and the distance between the hammers and the rotor cannot be adjusted as needed. Therefore, we propose a replaceable hammer for the crusher rotor body. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a replaceable hammer for the rotor of a crusher, which can quickly disassemble and assemble the hammer and adjust the distance between the hammer and the rotor as needed, thus effectively solving the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a replaceable hammer for a crusher rotor, comprising a central connector, a snap-fit ​​fixing assembly, a connecting fixing assembly, an adjusting assembly, and a hammer assembly;

[0007] Middle connector: A snap-fit ​​fixing component is installed at the upper end;

[0008] The snap-fit ​​fixing assembly includes a limiting rod, a first mounting cavity, a rotating block, a rotating handle, a second mounting cavity, a spring, and a blocking ring. The first mounting cavity is opened in the middle of the front end of the central connector. The rotating block is rotatably connected to the inner side of the first mounting cavity. The two ends of the rotating block are arc-shaped. The front end of the rotating block is fixedly connected to the rotating handle. The limiting rod is slidably connected to the left and right ends of the inner side of the central connector. The second mounting cavity is opened on the left and right sides of the inner side of the central connector. The blocking ring is fixedly connected to the outer side of the limiting rod. The blocking ring is slidably connected to the second mounting cavity. The spring is sleeved on the inner side of the second mounting cavity on the outer side of the limiting rod.

[0009] Connection and fixing components: Installed on the snap-fit ​​fixing components;

[0010] Adjustment component: mounted on the snap-fit ​​fixing component;

[0011] Hammer head assembly: mounted on the connecting and fixing assembly.

[0012] The rotating handle drives the rotating block to rotate within the mounting cavity. The arc-shaped end pushes the limiting rod to slide to both sides, and the spring is compressed and stores energy. When the middle connecting piece is inserted into the external fixing structure, the spring rebounds and connects the middle connecting piece with the plumb part, completing the connection between the hammer head assembly and the rotor body. The arc-shaped end of the rotating block enables the bidirectional limiting rod to move synchronously, and the spring drives the limiting device to reset. The whole assembly facilitates quick assembly and disassembly of the hammer head.

[0013] Furthermore, the snap-fit ​​fixing assembly also includes a connecting plate, a rectangular through hole, an arc-shaped fixing plate, and a circular pin. Two rectangular through holes are formed in the upper center of the central connector. The end of the limiting rod is fixedly connected to one end of the connecting plate, and the other end of the connecting plate is fixedly connected to the circular pin. The circular pin is slidably connected to the central connector, and the arc-shaped fixing plate is fixedly connected to the upper center of the central connector. The end of the limiting rod is linked to the circular pin through the connecting plate. When the limiting rod moves outward, the circular pin exits the circular slot of the U-shaped fixing head, and the arc-shaped fixing plate fits against the U-shaped fixing head to prevent lateral displacement. The pin and slot work together to achieve a double-fast connection between the hammer and the rotor body, and the rectangular through hole guides the pin's movement trajectory.

[0014] Furthermore, the connecting and fixing assembly includes a U-shaped fixing head, an adjusting threaded rod, a limiting groove, an arc-shaped fixing plate II, and a circular slot. The upper center of the U-shaped fixing head has a limiting groove, and the arc-shaped fixing plate II is slidably connected to the inner side of the limiting groove. The upper end of the arc-shaped fixing plate II is rotatably connected to the adjusting threaded rod, which is threadedly connected to the outer side of the U-shaped fixing head. Multiple circular slots are provided at both ends of the U-shaped fixing head, and a circular pin is slidably connected to the circular slots. The U-shaped fixing head is slidably connected to a rectangular through hole. Two dovetail-shaped sliding grooves are provided at the lower inner left and right ends of the U-shaped fixing head. Rotating the adjusting threaded rod pushes the arc-shaped fixing plate II to slide along the limiting groove, allowing the U-shaped fixing head and the arc-shaped fixing plate II to be easily fixed to the rotor body. The circular pin is inserted into the slot to lock the position.

[0015] Furthermore, the adjustment assembly includes a sliding frame, a sliding block, and a threaded rod. Two sliding frames are fixedly connected to the lower end of the central connector at both ends. A sliding block is slidably connected to the inner side of each sliding frame, and a threaded rod is rotatably connected to one end of each sliding frame. The threaded rod is threadedly connected to the sliding block. Rotating the threaded rod drives the sliding block to move back and forth within the sliding frame, thereby displacing the connecting handle and the hammer, adjusting the relative position of the hammer and the rotor body. The threaded rod provides precise position adjustment, and the sliding frame limits the sliding block's offset, adapting to different crushing conditions and extending the hammer's service life.

[0016] Furthermore, the hammer assembly includes a connecting handle and a dovetail-shaped slide groove. Two dovetail-shaped slide grooves are fixedly connected to the left and right ends of the connecting handle. These dovetail-shaped slide grooves are slidably connected to the dovetail-shaped slide groove on the inner side of the U-shaped fixing head. The middle of the front and rear ends of the connecting handle are fixedly connected to a sliding block by bolts. The connecting handle is slidably connected to the inner slide groove of the U-shaped fixing head via the dovetail-shaped slide groove, and the bolts fix the connecting handle to the sliding block, enabling quick assembly and disassembly of the hammer assembly. The dovetail-shaped slide groove features a two-way anti-detachment design, the bolt fixing enhances impact resistance, and the sliding block's linkage adjustment allows for adjustment of the hammer length as needed.

[0017] Furthermore, the hammer assembly also includes a hammer and hammer crushing particles. The hammer is fixedly connected to the lower end of the connecting handle. The lower end of the hammer is arc-shaped, and hammer crushing particles are provided at both ends of the hammer. The arc-shaped lower end of the hammer facilitates the crushing of materials. The hammer crushing particles are embedded on both sides of the hammer to enhance crushing efficiency, and the local reinforcement design of the crushing particles extends wear resistance.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: This replaceable hammer for the rotor of a crusher has the following advantages:

[0019] 1. This replaceable hammer for crusher rotor body has a rotating handle that drives the rotating block to rotate in the mounting cavity. The arc-shaped end pushes the limit rod to slide to both sides, and the spring is compressed and stores energy. When the middle connecting piece is inserted into the external fixing structure, the spring rebounds and connects the middle connecting piece with the pendant part, completing the connection between the hammer assembly and the rotor body. The arc-shaped end of the rotating block realizes the synchronous movement of the bidirectional limit rod. The spring drives the limit device to reset, making it easy to quickly disassemble and assemble the hammer.

[0020] 2. The replaceable hammers used in the crusher rotor are adjusted by a screw rod driving a sliding block to precisely adjust the hammer position to adapt to different crushing needs. They also facilitate the replacement of the hammers. The arc-shaped lower end of the hammer and the local reinforcement of crushed particles improve crushing efficiency and service life.
