Technical Field

[0001] The utility model relates to the technical field of crushers, in particular to a combined hammer head for a crusher. Background Art

[0002] The crusher hammer head is a hammer head of a hammer crusher. The hammer head is one of the core components of the hammer crusher. It is arranged on the hammer shaft of the crusher rotor. The hammer head directly strikes the material when the crusher is running at high speed, and finally breaks the material into a suitable particle size. It has good anti-mechanical impact and thermal shock performance, a wide range of applications, and can basically adapt to all crushing industries.

[0003] At present, the crusher hammer head is usually integrally formed. The hammer body and the hammer handle usually cannot be separated. After long-term use, the hammer head will be worn due to work. In particular, the bottom of the hammer body in contact with the material is severely worn, and the whole hammer head needs to be replaced, resulting in a high use cost and easy waste of resources.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-5 , a combined crusher hammer head, comprising: a hammer block 1, a hammer handle 2, a mounting hole 3, an insert block 4, a side plate 5, a connection hole 6, a hammer sleeve 7, a vertical rod 8, a through hole 9, a through hole 10, a slot 11, a sleeve hole 12, a screw 13, a screw block 14, a nut 15 and a transverse hole 16. Among them, a hammer handle 2 is inserted and arranged above the hammer block 1, and a mounting hole 3 is penetrated and opened in the upper part of the hammer handle 2, which is convenient for installing the hammer handle 2 on the crusher through the mounting hole 3. At the same time, a hammer sleeve 7 is sleeved at the bottom of the hammer block 1, so that the hammer handle 2 and the hammer sleeve 7 are respectively fixedly connected above and below the hammer block 1, ensuring the flexibility of the connection of the hammer head.

[0025] Please refer to Figures 1-5 , in order to realize the overall connection of the hammer block 1, the hammer handle 2 and the hammer sleeve 7, four vertical rods 8 are fixedly connected to the inner bottom wall of the hammer sleeve 7, and the vertical rods 8 are arranged around the hammer sleeve 7. At the same time, the vertical rods 8 are inserted and installed inside the hammer block 1, and a through hole 9 for accommodating the insertion of the vertical rods 8 is penetrated and opened inside the hammer block 1, ensuring the installation accuracy of the hammer sleeve 7 outside the hammer block 1. Considering the connection of the hammer handle 2 above the hammer block 1, side plates 5 are fixedly connected to both sides of the hammer handle 2, and the side plates 5 are arranged in contact with the top end of the hammer block 1. Specifically, a connection hole 6 for accommodating the insertion of the vertical rods 8 is penetrated and opened inside the side plates 5, and the connection hole 6 is correspondingly arranged above the through hole 9. Then, the vertical rods 8 are sequentially inserted and penetrated inside the hammer block 1 and the side plates 5, and a nut 15 is threadedly connected to the outer wall of the vertical rods 8, and the nut 15 is installed on the surface of the side plates 5, so that the nut 15 limits the top of the vertical rods 8, realizing the stable connection of the hammer handle 2 and the hammer sleeve 7 above and below with the hammer block 1, and the operation is simple and convenient, making the hammer head convenient for split disassembly and installation.

[0026] Please refer to Figures 1-5, in order to achieve the plugging stability of the hammer handle 2 inside the hammer block 1, a plug block 4 is fixedly connected to the bottom end of the hammer handle 2, and the plug block 4 is plugged on the surface of the hammer block 1 through a slot 11. Specifically, the slot 11 is opened on the surface of the hammer block 1, so that the hammer handle 2 is stably plugged inside the hammer block 1 through the plug block 4 and the slot 11. And considering the plugging effect of the plug block 4, a transverse hole 16 is opened inside the plug block 4. At the same time, a through hole 10 is correspondingly arranged outside the transverse hole 16, and the through hole 10 is penetrated through the side wall of the hammer block 1, so that the through hole 10 and the through hole 9 are vertically distributed, which is convenient for the hammer block 1 to be stressed in different directions and is beneficial to improving the overall stability of the hammer head. Further, a sleeve hole 12 is correspondingly arranged outside the through hole 10, and the sleeve hole 12 is penetrated through the side wall of the hammer sleeve 7, so that the transverse hole 16, the through hole 10 and the sleeve hole 12 are correspondingly arranged. By plugging and arranging a screw rod 13 on the side wall of the hammer sleeve 7 through the sleeve hole 12, the screw rod 13 is sequentially plugged inside the sleeve hole 12, the through hole 10 and the transverse hole 16, and the screw rod 13 is vertically arranged with the vertical rod 8, realizing the lateral limit of the hammer sleeve 7, the hammer block 1 and the hammer handle 2, ensuring the integrity of the hammer head, and threadedly connecting screw blocks 14 at both ends of the screw rod 13, and the screw blocks 14 are fitted and installed on the side wall of the hammer sleeve 7, so that the screw blocks 14 limit the installation of the screw rod 13 on both sides, ensuring the connection effect of the combined hammer head.

[0027] Working principle: When in use, the hammer sleeve 7 is sleeved and installed at the bottom of the hammer block 1 by plugging the vertical rod 8 inside the through hole 9, and the side plate 5 is installed at the top of the vertical rod 8 through the connecting hole 6, so that the hammer handle 2 is arranged at the top of the hammer block 1 through the side plate 5. By arranging a nut 15 on the surface of the side plate 5, under the action of the nut 15 being threadedly connected to the outer wall of the vertical rod 8, the hammer sleeve 7 and the hammer handle 2 are stably installed on both sides of the hammer block 1, ensuring the vertical connection effect of the combined hammer head. Moreover, the hammer handle 2 is plugged and installed above the hammer block 1 through the plug block 4. Under the action of the corresponding arrangement of the transverse hole 16, the through hole 10 and the sleeve hole 12, the screw rod 13 can apply synchronous lateral force to the hammer sleeve 7, the hammer handle 2 and the hammer block 1 through the transverse hole 16, the through hole 10 and the sleeve hole 12, and is limited by the screw blocks 14 on both sides, so that the combined hammer head is laterally stressed stably, ensuring the overall firmness of the hammer head. Moreover, through the three-stage setting, it is convenient for users to maintain and replace the hammer head, reducing the use cost. In this way, the working principle of the combined hammer head of the crusher is completed.
