Description

Technical Field

[0001] This utility model relates to the field of crusher technology, specifically to a high-strength hammer for crushers. Background Technology

[0002] Crusher hammers are the core components of a hammer crusher. They are arranged on the hammer shaft of the crusher rotor and directly strike the material when the crusher is running at high speed, ultimately crushing it into suitable particle sizes. They have good resistance to mechanical and thermal shock, a wide range of applications, and can be adapted to almost all crushing industries.

[0003] Currently, most existing crusher hammers are of one-piece design. When a hammer is damaged, the entire hammer needs to be replaced. This not only involves a complicated replacement operation, but also results in high operating costs due to the need to scrap the entire hammer. To address these issues, we have proposed a high-strength crusher hammer. Utility Model Content

[0004] The purpose of this invention is to provide a high-strength hammer for a crusher to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-strength hammerhead for a crusher, comprising:

[0006] The hammer base and hammer head body are provided. The hammer base has an installation groove and a plug-in seat is provided on the bottom wall of the hammer base. The plug-in seat is integrally formed with the hammer base. The bottom wall of the hammer base has two first plug-in slots, which are symmetrically arranged on both sides of the plug-in seat. The top wall of the hammer head body has a second plug-in slot, and the plug-in seat is movably inserted into the second plug-in slot. The top wall of the hammer head body has two connecting seats, which are symmetrically arranged on both sides of the second plug-in slot. Both connecting seats are integrally formed with the hammer head body and are movably inserted into the first plug-in slot. The connecting seats have two screw holes. Two fastening bolts are inserted into the screw holes through the through holes on both sides of the hammer base. The fastening bolts are threaded into the screw holes.

[0007] Preferably, two rows of reinforcing connecting columns are fixedly welded to the bottom wall of the hammer base, and the two rows of reinforcing connecting columns are symmetrically arranged on the front and rear sides of the plug-in base. Two rows of plug holes adapted to the reinforcing connecting columns are opened on the top wall of the hammer head body.

[0008] Preferably, the hammerhead body is made of cemented carbide steel.

[0009] Preferably, the bottom wall of the hammer head body is cast with a plurality of wear-resistant protrusions, and the wear-resistant protrusions are made of high-chromium cast iron.

[0010] Preferably, grooves are provided on both sides of the hammer base at the corresponding fastening bolt positions.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model divides the hammer head into a hammer base and a hammer head body. The hammer base is used to install and fix the hammer head on the crusher, and the hammer head body is used to hammer and crush materials. The hammer head body is made of cemented carbide steel. Cemented carbide steel has higher hardness, bending strength and impact resistance, thermal fatigue resistance, good thermal hardness and low cost. It can greatly improve the service life of the hammer head body and reduce the replacement frequency. When the hammer head body is damaged, only the hammer head body needs to be removed and replaced. There is no need to replace the whole hammer head. This not only greatly improves the convenience of replacement operation, but also avoids the problem of high scrap cost of whole hammer head replacement. It is worth promoting.

[0013] 2. This utility model achieves the connection between the hammer head body and the hammer base by the insertion and engagement of the plug-in seat with the second plug-in slot, the insertion and engagement of the connecting seat with the first plug-in slot, and the insertion and engagement of the reinforcing connecting post with the plug hole, thereby improving the connection strength between the hammer head body and the hammer base and ensuring the stability of the hammer head body installation.

[0019] 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.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a high-strength hammer for a crusher, comprising:

[0021] The hammer base 1 and the hammer head body 2 are provided. The hammer base 1 has an installation groove 3 and a plug-in seat 4 is provided on the bottom wall of the hammer base 1. The plug-in seat 4 is integrally formed with the hammer base 1. The bottom wall of the hammer base 1 has two first plug-in grooves 5, which are symmetrically arranged on both sides of the plug-in seat 4. The top wall of the hammer head body 2 has a second plug-in groove 6, and the plug-in seat 4 is movably inserted into the second plug-in groove 6. The top wall of the hammer head body 2 has two connecting seats 7, which are symmetrically arranged on both sides of the second plug-in groove 6. Both connecting seats 7 are integrally formed with the hammer head body 2 and are movably inserted into the first plug-in grooves 5. The connecting seats 7 have two screw holes 8. Two fastening bolts 9 are inserted into the through holes on both sides of the hammer base 1. The fastening bolts 9 are threaded into the screw holes 8.

[0022] Two rows of reinforcing connecting columns 10 are fixedly welded to the bottom wall of the hammer base 1. The two rows of reinforcing connecting columns 10 are symmetrically arranged on the front and rear sides of the plug-in seat 4. Two rows of plug holes 11 adapted to the reinforcing connecting columns 10 are opened on the top wall of the hammer head body 2. By connecting the reinforcing connecting columns 10 with the plug holes 11, the connection between the hammer base 1 and the hammer head body 2 can be strengthened, and the force of the plug-in seat 4 and the connecting seat 7 can be shared.

[0023] The hammerhead body 2 is made of cemented carbide steel, which has higher hardness, bending strength and impact resistance, thermal fatigue resistance, good thermal hardness and low cost, which can greatly improve the service life of the hammerhead body 2.

[0024] The bottom wall of the hammerhead body 2 is cast with multiple wear-resistant protrusions 12. The wear-resistant protrusions 12 are made of high-chromium cast iron, which is a high-performance wear-resistant material with good high-temperature resistance and corrosion resistance, thereby greatly improving the wear resistance of the hammerhead body 2.

[0025] The hammer base 1 has grooves 13 on both sides at the corresponding fastening bolts 9. The grooves 13 can prevent the fastening bolts 9 from protruding from the hammer base 1 and reduce the probability of the fastening bolts 9 being damaged by impact.

[0026] Working principle: This utility model divides the hammer head into a hammer base 1 and a hammer head body 2. The hammer base 1 is used to install and fix the hammer head on the crusher, and the hammer head body 2 is used to hammer and crush materials. The hammer head body 2 is made of cemented carbide steel. Cemented carbide steel has higher hardness, bending strength and impact resistance, thermal fatigue resistance, good thermal hardness and low cost, which can greatly improve the service life of the hammer head body 2 and reduce the replacement frequency. When the hammer head body 2 is damaged, only the hammer head body 2 needs to be removed and replaced, without the need for overall replacement. This not only greatly improves the convenience of replacement operation, but also avoids the problem of high scrap costs from overall replacement, which is worth promoting.
