Description

Technical Field

[0001] This utility model relates to the field of crusher technology, and in particular to a crusher hammer based on ceramic particles inlaid with high manganese steel. Background Technology

[0002] A crusher is a device that breaks large materials into smaller ones. There are many types of crushers. Among them, the hammer crusher is a medium and fine crushing device that uses high-speed rotating hammers to impact, shear, and grind materials. It is widely used in industries such as mining, cement, and building materials.

[0003] Hammer crushers' hammers are in constant crushing operation, resulting in rapid wear. Since the hammers are a single piece, the entire hammer needs to be replaced. However, in reality, only the hammer crown is severely damaged, while the hammer handle is rarely damaged. Replacing the entire hammer together wastes resources and increases costs.

[0022] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0023] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0024] This embodiment mainly describes a crusher hammer based on ceramic particles embedded in high-manganese steel, as detailed below:

[0025] like Figures 1-2 As shown, the crusher hammer based on ceramic particles inlaid with high manganese steel includes a hammer, a rotating shaft and a motor. Several turntables 2 are fixedly installed on the rotating shaft. The turntables 2 are arranged perpendicular to the axis of the rotating shaft. The rotating shaft is provided with ribs 6 and the turntables 2 are provided with grooves 5. The ribs 6 are inserted into the grooves 5 so that the turntables 2 rotate synchronously with the rotating shaft. Connecting shafts 3 are passed through the turntables 2. Specifically, there are four connecting shafts 3, which are evenly distributed on the turntables 2.

[0026] The hammerhead is mounted on the connecting shaft 3. Four hammerheads are set between each of the two adjacent turntables 2. Supports 1 are set at both ends of the rotating shaft. Bearings are fixedly installed inside the support 1. The two ends of the rotating shaft pass through the bearings and are mounted on the support 1. A pulley is set at one end of the rotating shaft. The rotating shaft is connected to the motor through the pulley. The motor drives the rotating shaft to rotate through the pulley. The connecting shaft 3 and the turntable 2 rotate through the rotating shaft to swing the hammerheads for crushing operations.

[0027] like Figure 3 As shown, the hammer head consists of a hammer crown 7 and a hammer handle 8. The hammer head is made of a material inlaid with ceramic particles and high manganese steel, which combines the high hardness and wear resistance of ceramic particles with the toughness of high manganese steel, effectively improving the performance and service life of the hammer head in crushing operations.

[0028] like Figure 4 As shown, an assembly hole 15 is provided on the tail end of the hammer handle 8, and the hammer handle 8 is sleeved on the connecting shaft 3 through the assembly hole 15.

[0029] The hammer crown 7 is detachably mounted on the hammer handle 8. Specifically, the hammer crown 7 is provided with a groove 9, and the top of the hammer handle 8 is provided with a connector 11. The connector 11 is dovetail shaped. The hammer crown 7 moves along the axial direction of the connecting shaft 3 to engage the connector 11 into the groove 9. The connector 11 and the groove 9 are interference fit. When the connecting shaft 3 swings the hammer head to perform crushing operations, the groove 9 limits the movement of the hammer crown 7 in the radial direction of the connecting shaft 3 through the connector 11, preventing the hammer handle 8 from throwing the hammer crown 7 out.

[0030] like Figures 5-6 As shown, a stop pin 17 is provided inside the hammer handle 8. The stop pin 17 extends from the connector 11 and is inserted into the hammer crown 7. Specifically, a through hole 16 is provided inside the hammer handle 8 for the stop pin 17 to pass through. One end of the through hole 16 is provided on the inner wall of the mounting hole 15, and the other end is provided on the top surface of the connector 11. The through hole 16 is perpendicular to the top surface of the connector 11 and the axis of the connecting shaft 3.

[0031] The hammer crown 7 is provided with a slot 10 corresponding to the through hole 16. Specifically, the slot 10 is provided corresponding to the end of the through hole 16 on the surface of the connector 11, and the slot 10 extends from the surface of the slot 9 into the hammer crown 7.

[0032] When installing the stop pin 17, first insert the stop pin 17 into the through hole 16 of the hammer handle 8, then fasten the hammer crown 7 to the connector 11 with an interference fit. After fastening, insert the stop pin 17 through both the through hole 16 and the slot 10, and insert it into the hammer handle 8 and the hammer crown 7. When the hammer head is performing crushing operations, the stop pin 17 limits the movement of the hammer crown 7 in the axial direction of the connecting shaft 3 through the slot 10, preventing the hammer head from hitting the crushed stone and throwing the hammer crown 7 out during the crushing operation.

[0033] One end of the connecting shaft 3 is provided with a transition shaft 13 and a limiting ring 12. The axes of the connecting shaft 3, the transition shaft 13 and the limiting ring 12 are the same.

[0034] The transition shaft 13 is fixedly installed on one side of the connecting shaft 3. The cross-sectional diameter of the transition shaft 13 is smaller than that of the connecting shaft 3. When the hammer crown 7 needs to be replaced, the hammer handle 8, which is sleeved on the connecting shaft 3, is moved to one end of the transition shaft 13. Because the cross-sectional diameter of the transition shaft 13 is smaller than that of the connecting shaft 3, when the hammer handle 8 is moved to the transition shaft 13, the stop pin 17 set in the hammer handle 8 slides out from the through hole 16. At this time, the hammer crown 7 can be moved in the radial direction of the connecting shaft 3 to remove and replace it without replacing the hammer handle 8, thus saving costs. After the replacement is completed, the stop pin 17 is inserted into the through hole 16 to limit the movement of the hammer crown 7 in the axial direction of the connecting shaft 3, and the hammer handle 8 is more easily and accurately sleeved into the connecting shaft 3 through the transition shaft 13.

[0035] like Figure 1 , Figure 7As shown, the limiting ring 12 and the transition shaft 13 are located on the same side. The limiting ring 12 is hollow and can be detachably sleeved on the connecting shaft 3. Specifically, the limiting ring 12 is composed of a first locking block 18 and a second locking block 19. One end of the limiting ring 12 abuts against the turntable 2, and a fixing ring 14 is provided on the other end. The sides of the first locking block 18 and the second locking block 19 are evenly provided with screw holes. The fixing ring 14 is fixedly set on one side of the first locking block 18 and the second locking block 19 by screws, thus fastening the first locking block 18 and the second locking block 19.

[0036] The limiting ring 12 surrounds the transition shaft 13 through its hollow part to prevent the hammer from hitting the crushed stone during the crushing operation and causing the hammer to slide on the connecting shaft 3 into the transition shaft 13, thus causing the hammer to come out. When it is necessary to replace the hammer crown 7, loosen the screws of the fixing ring 14, the first locking block 18 and the second locking block 19, remove the fixing ring 14, and then remove the first locking block 18 and the second locking block 19. Then the hammer handle 8 can be slid to the transition shaft 13 to disassemble and replace the hammer crown 7.
