Description

Technical Field

[0001] The utility model relates to the technical field of crusher hammer heads, in particular to a wear-resistant crusher hammer head structure. Background Art

[0002] A crusher, also known as a stone crusher, is a crushing machine used in the processing process that can break the mined raw ore into small particles through extrusion and bending.

[0003] According to the existing technology, the hammer head of the crusher is currently made of alloy forging. Although the overall strength is high enough, it directly hits the ore when in use. The force is mutual, generating enough force to crush the stone, and the striking hammer will also be subjected to the same force. After using it for too long, it will affect the service life of the striking hammer. At the same time, after the striking hammer is connected by a rotating shaft, a gap will be formed between the striking hammers. If the crushed stone is stuck in the gap, it will cause extrusion pressure between the striking hammers, which will cause friction between the rotating shaft and the striking hammer, thereby causing deformation of equipment parts and affecting the overall service life of the equipment. Utility Model Content

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technology.

[0005] To this end, the technical solution adopted by the utility model is: a wear-resistant crusher hammer head structure, including a connecting rod, one end of the connecting rod is fixedly connected to a striking hammer, both sides of the striking hammer are slidably connected to buffer blocks in a through-shaped manner, one side of the buffer block is fixedly connected to a friction block, one side of the friction block is slidably connected to a transport rod, the surface of the transport rod is fixedly connected to a threaded strip, one side of the buffer block is symmetrically fixedly connected to a spring, one end of the spring is fixedly connected to a support block, one side of the buffer block is fixedly connected to a limit rod, and the limit rod is L-shaped;

[0006] A wear-resistant layer is pressed on the surface of the striking hammer, a buffer layer is pressed on one side of the wear-resistant layer, and a reinforcement layer is pressed on one side of the buffer layer.

[0007] Preferably, reinforcing ribs are fixedly connected to both sides of the connecting rod.

[0008] Preferably, the conveying rod is slidably connected to the side wall of the striking hammer in a penetrating manner, and the number of the conveying rods on each side of the striking hammer is four.

[0009] Preferably, both ends of the support block are fixedly connected to the inner wall of the striking hammer, and the limiting rod is slidably connected to the side wall of the support block in a penetrating manner.

[0010] Preferably, the wear-resistant layer is forged from a combination of chromium and molybdenum.

[0011] Preferably, the buffer layer is forged from a combination of iron and nickel.

[0012] Preferably, the reinforcement layer is made of carbon steel.

[0013] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0014] 1. A transport rod is provided in the utility model. When the buffer block collides, it drives the friction block to move. When the friction block moves, it can rub against the transport rod. When rubbing, the transport rod can be rotated. When the transport rod rotates, the threaded bar can push the gravel stuck between the striking hammers, thereby reducing the gravel stuck between the striking hammers, thereby ensuring the service life of the equipment.

[0015] 2. A protective layer is provided in the utility model. The wear-resistant layer can ensure the wear resistance of the striking hammer and ensure its service life. A buffer layer is provided. When striking, the force is absorbed by the buffer layer, thereby offsetting the impact force. The reinforcement layer serves as the bottom layer. Under multiple impacts, the reinforcement layer becomes tighter and tighter during striking, thereby improving the strength of the striking hammer. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0022] A wear-resistant crusher hammer structure provided by some embodiments of the utility model will be described below in conjunction with the accompanying drawings.

[0023] Combination Figure 1-3 As shown, the utility model provides a wear-resistant crusher hammer structure, including a connecting rod 1, one end of the connecting rod 1 is fixedly connected to a striking hammer 2, both sides of the striking hammer 2 are slidably connected to buffer blocks 3 in a through-shaped manner, one side of the buffer block 3 is fixedly connected to a friction block 4, one side of the friction block 4 is fitted and slidably connected to a transport rod 5, the surface of the transport rod 5 is fixedly connected to a threaded strip, one side of the buffer block 3 is symmetrically fixedly connected to a spring 6, one end of the spring 6 is fixedly connected to a support block 8, one side of the buffer block 3 is fixedly connected to a limit rod 7, and the limit rod 7 is L-shaped;

[0024] Reinforcing ribs 12 are fixedly connected to both sides of the connecting rod 1, the conveying rod 5 is slidably connected to the side wall of the striking hammer 2 in a penetrating manner, there are four conveying rods 5 on each side of the striking hammer 2, both ends of the supporting block 8 are fixedly connected to the inner wall of the striking hammer 2, and the limiting rod 7 is slidably connected to the side wall of the supporting block 8 in a penetrating manner.

[0025] In the first embodiment, the striking hammer 2 strikes the ore while rotating. When the buffer block 3 strikes the ore, the impact force acts on the buffer block 3. When the buffer block 3 moves, the friction block 4 can be driven to move. The friction block 4 will fit and rub against the conveying rod 5, thereby driving the conveying rod 5 to move. This can prevent the crushed stone from being stuck between the striking hammers 2, thereby preventing the crushed stone from damaging the striking hammer 2 and the rotating shaft, thereby ensuring the service life of the equipment parts.

[0026] A wear-resistant layer 9 is pressed on the surface of the striking hammer 2, a buffer layer 10 is pressed on one side of the wear-resistant layer 9, and a reinforcement layer 11 is pressed on one side of the buffer layer 10.

[0027] In the second embodiment, the wear-resistant layer 9 is used to ensure that it will not be easily worn when striking the ore, thereby ensuring the service life of the striking hammer 2. The buffer layer 10 is used to absorb the impact force to avoid damage to the striking hammer 2 caused by excessive impact force. The reinforcement layer 11 is used to gradually increase the strength of the reinforcement layer 11 after multiple strikes. After the improvement, it can not only meet the requirements of subsequent recycling, but also increase the strength of the striking hammer 2 and extend the service life of the striking hammer 2.

[0028] The working principle and use process of the utility model are as follows: when the buffer block 3 on the striking hammer 2 hits the ore, it will drive the buffer block 3 to move, and when the buffer block 3 moves, it can drive the friction block 4 to move, and when the friction block 4 moves, it can drive the conveying rod 5 to rotate, and when the conveying rod 5 rotates, it can rotate through the threaded bar, and the wear resistance of the surface of the striking hammer 2 can be enhanced by the wear-resistant layer 9, the buffer layer 10 can absorb the impact force, and the reinforcement layer 11 can make the striking hammer 2 stronger and stronger with use.
