Abstract
Description
Technical Field
[0001] This utility model relates to the field of crusher hammer technology, specifically a combined crusher hammer with a detachable structure. Background Technology
[0002] Crusher hammers are the core components of hammer crushers. They are installed on the hammer shaft of the rotor and directly strike materials to a suitable particle size through high-speed rotation. They are widely used in industrial crushing fields such as mining, coal, and coke.
[0003] Traditional crusher hammers are all one-piece designs. When they are worn out and need to be replaced, the hammer shaft must be removed to remove the hammer, which is laborious and time-consuming. Moreover, the wear of the hammer handle is relatively small, and replacing the whole hammer is wasteful. Therefore, existing technology has developed a combined crusher hammer with a detachable structure, such as the patent document CN216856896U entitled "A Detachable Combined Crusher Hammer". The hammer and hammer handle are connected by a detachable connection, so there is no need to replace the whole hammer.
[0004] However, most of the structural components of its connecting mechanism are exposed on the outside. During use, they are easily damaged by impacts from materials such as stones and coal entering the crusher chamber. Damage not only affects the stability of the connection between the hammer handle and the hammer head, but also reduces the smoothness of subsequent disassembly and replacement of the hammer handle.

[0022] 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.
[0023] See Figures 1-4 This utility model provides the following two technical solutions:
[0024] First implementation: A combined crusher hammer with a detachable structure, including a hammer handle 1 and a hammer head 2;
[0025] The bottom of the hammer handle 1 is provided with a top plate 3, and U-shaped mounting plates 4 are provided on both sides of the bottom of the top plate 3. Bolts 5 are evenly arranged on the U-shaped mounting plates 4, and the bolts 5 are connected to the hammer head 2, so that the hammer handle 1 and the hammer head 2 can be detachably connected.
[0026] The bottom of the top plate 3 is provided with a mounting block 6, and the bottom of the mounting block 6 is provided with an electric telescopic rod 7. The output end of the electric telescopic rod 7 is provided with a connecting rod 8. Both ends of the connecting rod 8 are connected to the frame 9. The top of the hammer handle 1 is provided with a groove 10, and the top of the frame 9 extends into the groove 10. The bottom of the frame 9 contacts the hammer head 2, and the hammer head 2 contacts the U-shaped mounting plate 4. The top plate 3, the U-shaped mounting plate 4, the bolt 5, the mounting block 6, the electric telescopic rod 7, and the connecting rod 8 are all located inside the frame 9. This protects the above structure without affecting the disassembly and assembly of the hammer head 2 and the hammer handle 1. As a result, only the hammer head 2, the hammer handle 1, and the frame 9 are exposed on the outside. Therefore, when hit by materials, damage to the internal structure can be avoided, ensuring the stability of the connection and the smoothness of subsequent disassembly and replacement.
[0027] The top plate 3 is equipped with screws 11 around its perimeter that connect to the hammer handle 1, and the mounting block 6 is equipped with screws 12 at both ends that connect to the top plate 3, making it easy to assemble and disassemble the top plate 3 and the mounting block 6.

The battery supplies power to the electrical components, and the wireless communication module 14 is electrically connected to the controller 13. The wireless communication module 14 is connected to a mobile terminal. By controlling the mobile terminal, the wireless communication module 14 sends a control signal to the controller 13, which in turn controls the electric telescopic pole 7 to extend and retract, thus moving the frame 9.
[0029] The U-shaped mounting plate 4 has a U-shaped groove, and the connecting rod 8 is located in the U-shaped groove, which can avoid the connecting rod 8 and does not affect the movement of the frame 9 driven by the connecting rod 8.
[0030] The outer side of the frame 9 is provided with a buffer frame 15 that contacts both the groove 10 and the hammer head 2. It is made of rubber material, which can improve the buffering capacity of the frame 9 and thus improve the service life of the frame 9.
[0031] The second implementation method differs from the first implementation method in that: both ends of the U-shaped mounting plates 4 on opposite sides are provided with bending portions 16, and the bending portions 16 are in contact with the hammer head 2, which can position the hammer head 2 for installation, so as to make it easier to install the bolts 5.
[0032] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.
[0033] When in use, only the hammer head 2, hammer handle 1 and frame 9 are exposed on the outside, which can prevent damage to the internal structure when hit by materials, ensuring the stability of the connection and the smoothness of subsequent disassembly and replacement.
[0034] When it is necessary to disassemble the hammer head 2, the wireless communication module 14 sends a control signal to the controller 13 through the operation of the mobile terminal, so that the controller 13 can control the electric telescopic rod 7 to extend and retract, thereby moving the frame 9 and exposing the bolt 5 for disassembly. After disassembly and replacement, the frame 9 can be reset.
