Description

Technical Field

[0001] This utility model relates to the field of crushing equipment technology, and in particular to a crushing hammer for mining materials. Background Technology

[0002] A hammer crusher is a device that uses the combined action of high-speed impact and low-speed crushing to crush materials. A hammer crusher is usually composed of a hammer crusher box, rotor, hammers, impact liners, screen plates, etc. Among them, the hammers of the hammer crusher strike the material by hammering to crush it.

[0003] Hammer crushers are widely used, and are essential for crushing mineral materials during processing. The crushing hammer is a crucial component of the hammer crusher. However, current hammer crusher hammers are typically installed by sleeve-mounting the hammer head above the hammer rod, with one end of the rod secured by a single nut or pin. This method of hammer installation is not very secure. Prolonged crushing of mineral materials by the hammer head generates significant vibration, easily leading to loosening of the nut or breakage of the pin due to vibration. This results in unstable hammer operation or even hammer head detachment, affecting the crushing effect of the crusher and potentially causing equipment damage and safety accidents. Therefore, to address these issues, we have developed a new type of crushing hammer for mineral materials. Utility Model Content

[0011] A further preferred embodiment of this utility model is: multiple turntables are fixedly connected to the outer surface of the drive rod, and each turntable has a circular hole on its outer surface, with the hammer rod located inside the circular hole.

[0012] Compared with the prior art, the present invention has the following advantages: 1. The mining material crushing hammer head, through the threaded hole of the locking screw through the threaded fixing ring, can engage with the threaded positioning groove of the hammer rod, which will restrict axial sliding. The double locking of the left threaded locking cap and the left anti-loosening washer enhances the sealing and anti-loosening performance. At the same time, the right side is fitted with the limiting end of the hammer rod by the threaded limiting seat, and the right threaded locking cap is compacted and fixed, which can effectively offset the high-frequency vibration of crushing, avoid the problems of nut loosening and pin breakage in traditional fixing, prevent the hammer head from falling off, ensure stable crushing effect, and reduce the risk of equipment damage and safety accidents.

[0013] 2. This mining material crushing hammer, by placing the hammer head between multiple turntables and having the hammer rod sequentially inserted into the mounting holes of the left and right fixed discs and the circular holes of the turntables, can be positioned using multiple sets of holes to ensure the coaxiality of the hammer rod's lateral installation. This also allows the connecting end of the hammer head to be stably fitted onto the surface of the hammer rod, enabling the hammer head body to be suspended and subjected to balanced force. This avoids the hammer head tilting caused by positioning deviations in traditional assembly. At the same time, the spaced support of multiple turntables reduces the radial shaking of the hammer head during crushing and reduces collision damage between the hammer head and other parts of the equipment.

[0019] This embodiment mainly describes the crushing hammer for mining materials, as follows: Figures 1-5As shown, the mining material crushing hammer includes a drive rod 1 and a hammer head component 4. The hammer head component 4 includes a hammer head body 402, a crushing and wear-resistant part 403, and a connecting end 401. The connecting end 401 is made of ZGMn13 high manganese steel, which can absorb vibration through plastic deformation and has a certain degree of wear resistance. The hammer head body 402 is made of low alloy wear-resistant steel, which can reduce cracks in the body caused by impact. The crushing and wear-resistant part 403 directly contacts hard materials such as ore and is made of high chromium cast iron. The crushing and wear-resistant part 403 is located at the bottom end of the hammer head body 402, and the connecting end 401 is located at the top end of the hammer head body 402. A right fixed plate 3 and a left fixed plate 2 are fixedly connected to the outer surface of the drive rod 1. The inner rings of the right fixed plate 3 and the left fixed plate 2 are fixedly connected to the outer surface of the drive rod 1. Multiple mounting holes 5 are provided on one side of the right fixed plate 3 and one side of the left fixed plate 2. The hammer rod 6 is provided inside two mounting holes 5. Each connecting end 401 is sleeved on the outer surface of the hammer rod 6. Specifically, the mounting holes 5 of the right fixed plate 3 and the left fixed plate 2 provide a transverse passage for the hammer rod 6, so that the hammer rod 6 can be fixed across the two plates. The hammer head 4 is sleeved on the surface of the hammer rod 6 through the connecting end 401 to achieve connection with the support frame. The hammer head body 402 serves as a load-bearing structure. The crushing and wear-resistant part 403 at its bottom directly contacts the material to ensure wear resistance during the crushing process.

[0020] A series of threaded retaining rings 13 arranged in a ring are fixedly connected to one side of the left fixed plate 2. Each threaded retaining ring 13 has a threaded hole 14 on one side. A locking screw 16 is threadedly connected to the inner wall of one threaded hole 14. A threaded positioning groove 15 is formed on the outer surface of the hammer rod 6, and the outer surface of the locking screw 16 is threadedly connected to the inner wall of the threaded positioning groove 15. A left threaded locking cap 17 is threadedly connected to the outer surface of one threaded retaining ring 13. A threaded end 18 is provided on one side of the left threaded locking cap 17. A threaded fixing groove 19 is formed at one end of the hammer rod 6, and the outer surface of the threaded end 18 is threadedly connected to the inner wall of the threaded fixing groove 19. The inner surface of the left threaded locking cap 17 is threadedly connected to the inner wall of the threaded fixing groove 19. The part is equipped with a left anti-detachment washer 20, one side of which contacts one end of the hammer rod 6. Specifically, the threaded fixing ring 13 on the left fixing plate 2 provides an installation reference for the locking component, while the threaded hole 14 allows the locking screw 16 to be screwed in. The locking screw 16 is threadedly connected to the threaded positioning groove 15 of the hammer rod 6, which can limit the axial sliding of the hammer rod 6. The left threaded locking cap 17 is sleeved on the outside of the threaded fixing ring 13, and its threaded end 18 is screwed into the threaded fixing groove 19 of the hammer rod 6, which can form a secondary fixation. The internal left anti-detachment washer 20 is close to the end of the hammer rod 6, which enhances the sealing performance and further prevents loosening. The double protection prevents the left side of the hammer rod 6 from shifting due to vibration.

[0021] Multiple threaded limiting seats 9 are fixedly connected to one side of the right fixed plate 3. Each hammer rod 6 has a limiting end 8 at the other end, and the outer surface of the limiting end 8 is in contact with the inner wall of the threaded limiting seat 9. A right threaded locking cap 12 is threadedly connected to the outer surface of one threaded limiting seat 9. A right anti-disengagement washer 7 is fitted on the outer surface of each threaded limiting seat 9, and one side of the right threaded locking cap 12 is in close contact with one side of the right anti-disengagement washer 7. Multiple turntables 10 are fixedly connected to the outer surface of the drive rod 1. Each turntable 10 has an opening on its outer surface. The circular hole 11 is located inside the hammer rod 6. Specifically, the threaded limiting seat 9 on the right fixed plate 3 fits with the limiting end 8 of the hammer rod 6, providing a basic limit for the right side of the hammer rod 6. The right anti-loosening washer 7 is fitted outside the threaded limiting seat 9, and with the compaction effect of the right threaded locking cap 12, it will form a right-side anti-loosening fixation. Multiple turntables 10 on the drive rod 1 are fitted outside the hammer rod 6 through the circular hole 11, and each forms multiple points of support with the left and right discs to ensure the coaxiality of the hammer rod 6 in the lateral installation and reduce radial shaking during crushing.

[0022] Working principle: During assembly, the hammer head 4 is placed between multiple turntables 10. Then, the hammer rod 6 passes through the mounting holes 5 of the left fixed plate 2 and the right fixed plate 3 in sequence, and through the circular hole 11 of the turntable 10. The coaxiality of the hammer rod 6 is ensured by the hole positioning, allowing the connecting end 401 of the hammer head 4 to be sleeved on the surface of the hammer rod 6, and allowing the hammer head body 402 to be suspended. During anti-loosening fixing, the locking screw 16 passes through the threaded hole 14 of the threaded retaining ring 13, which can be threadedly connected with the threaded positioning groove 15 on the surface of the hammer rod 6, restricting the hammer... The rod 6 slides axially, while the left threaded locking cap 17 is fitted outside the threaded fixing ring 13. Its threaded end 18 is screwed into the threaded fixing groove 19 of the hammer rod 6. The left anti-loosening washer 20 enhances the sealing and anti-loosening performance. The right side is limited by the threaded limiting seat 9. The limiting end 8 of the hammer rod 6 fits against the inner wall of the threaded limiting seat 9. The right anti-loosening washer 7 is fitted outside the threaded limiting seat 9 and then tightened by the right threaded locking cap 12. The double-sided multi-fixing structure can offset the high-frequency vibration during breakage and avoid the problems of nut loosening and pin breakage in traditional fixing.
