Description

Technical Field

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

[0002] In the application of hammer crushers, the hammer is a key component for crushing operations, and its performance directly affects crushing efficiency, crushing effect, and the overall operating cost of the equipment. Traditional hammer crusher hammer designs often have some problems that limit the performance and flexibility of the equipment.

[0003] First, traditional hammerheads typically have a fixed structure and lack an adjustment mechanism. This means that once the hammerhead is installed on the crusher, its height is difficult to adjust, thus limiting the equipment's adaptability to different materials and crushing requirements. During the crushing process, if the hammerhead's position or angle is inappropriate, it may lead to poor crushing results or even damage to the equipment.

[0004] Secondly, the design of the contact components in traditional hammerheads is often not optimized. Some traditional hammerheads have an unreasonable bottom design for the contact components, lacking crushing teeth or having unevenly distributed crushing teeth, making it difficult for materials to be effectively crushed and separated during the crushing process.

[0005] Furthermore, the replacement and maintenance of traditional hammerhead components present certain difficulties. Since the various parts of the hammerhead are typically fixed together by fasteners or welding, when a component wears out or is damaged, the entire hammerhead often needs to be replaced or a complex repair operation performed. This not only increases maintenance costs but may also lead to excessive downtime, affecting production schedules. Therefore, we propose a new hammerhead for hammer crushers. Utility Model Content

This enhances the stability and firmness of the connection between the fixing member 2 and the movable member 3, ensuring that the adjusting knob 32 has a sufficient adjustment range.

[0033] When using the hammer head of the hammer crusher of this utility model:

[0034] First, the overall structure of the hammer head consists of a connector 1, a fixing part 2, a movable part 3, and a contact part 4 arranged from top to bottom. The components are connected in a specific way to achieve a stable and adjustable assembly.

[0035] Connection and Fixing: Connector 1 mainly includes a collar 10 and a fixing plate 11. The collar 10 is used to connect to the drive part of the crusher, and the fixing plate 11 is tightly fixed to the fixing part 2 by two first fixing bolts 12 to ensure the stability and safety of the hammer in the crushing operation. The insert plate 13 on the fixing plate 11 is inserted into the socket 20 on the fixing part 2, which not only improves the connection accuracy, but also facilitates installation and disassembly, enhancing the convenience of operation.

[0036] Height and Angle Adjustment: The bottom of the fixed part 2 is threadedly connected to the adjustment knob 32 on the top of the movable part 3 via two connecting screws 22. This design allows the user to adjust the height and angle of the movable part 3 relative to the fixed part 2 by rotating the adjustment knob 32, thereby enhancing the adaptability and flexibility of the hammerhead to adapt to different materials and crushing needs. The bottom end of the connecting screw 22 extends into the movable part 3, and its length is greater than or equal to the height of the first connecting block 21, ensuring the stability and firmness of the connection between the fixed part 2 and the movable part 3, while also ensuring that the adjustment knob 32 has a sufficient adjustment range.

[0037] Crushing operation: Contact element 4 is the part of the hammer that directly contacts the material being crushed. Its bottom is arc-shaped and equipped with crushing teeth 40. This design helps to improve crushing efficiency and effect, making the material easier to crush and separate. Contact element 4 is fixedly connected to the bottom of movable element 3 by several symmetrically arranged second fixing bolts 41, ensuring stability and safety during the crushing process.

[0038] Easy maintenance and replacement: The movable part 3 and the contact part 4 are connected by the insertion and engagement of the second connecting block 31 and the second connecting groove 42. This design not only improves the accuracy and stability of the connection, but also facilitates quick positioning during installation and disassembly, thus enhancing the convenience of maintenance. Since the connecting part 1 and the fixed part 2, as well as the movable part 3 and the contact part 4, are all designed to be detachable and fixed, when a component is worn or damaged, it can be easily replaced, reducing maintenance costs and downtime.

[0039] In summary, the hammer head for the hammer crusher of this utility model, through its reasonable structural design and easy adjustment and component replacement, can effectively improve crushing efficiency and effect, while reducing maintenance costs and downtime, providing a more flexible and efficient solution for crushing operations.
