Technical Field

[0001] This utility model relates to the field of crusher hammers, specifically crusher hammers and crusher hammer assemblies. Background Technology

[0002] The crusher hammer is a key working component of the crusher, mainly used to strike, impact, shear and grind materials to crush them into the required particle size. When the crusher is working, the hammer rotates at high speed with the rotor and comes into direct contact with the material to crush it.

[0003] In current crusher operation, the common crusher hammer and support cylinder adopt an integrated welded structure. Under frequent impact and friction, the hammer, as a key component that directly contacts the material, is prone to wear, breakage and other damage. Once the hammer shows local wear, the entire hammer assembly and support cylinder need to be replaced. It is not possible to disassemble and replace the hammer assembly and hammer cylinder, which increases the operating cost of the hammer assembly in the crusher. Therefore, we propose a crusher hammer and crusher hammer assembly to solve the above problems. Utility Model Content

Each connecting hole has a connecting block inside, and a hammer is fixedly connected to the side of each connecting block that is far apart from each other. A circular hole is opened on the outer surface of each connecting block. Multiple fixing rods are provided inside the support cylinder, and a limit plate is fixedly connected to one end of each fixing rod. An annular arrangement of first through holes is opened on one side of the right end plate.

[0006] As a further improvement of this utility model: one end of each fixing rod passes through the first through hole and extends to one side of the first through hole, and a locking nut is threaded onto the outer surface of one end of each fixing rod.

[0007] As a further improvement of this utility model: multiple second through holes are provided on the side of the right end plate and the left end plate that are close to each other, and threaded grooves are provided on both ends of the support cylinder in annular arrangement.

[0019] The crusher hammer and crusher hammer assembly include a support cylinder 1. A right end plate 3 is located on one side of the support cylinder 1, and a left end plate 2 is located on another side. The outer surface of the support cylinder 1 has annularly arranged connecting holes 4. Each connecting hole 4 contains a connecting block 5. A hammer component 6 is fixedly connected to the opposite side of each connecting block 5. The surface of the hammer component 6 is covered with a wear-resistant layer made of high-chromium alloy. An elastic sealing ring is provided between the connecting block 5 and the inner wall of the connecting hole 4. A circular hole 7 is located on the outer surface of each connecting block 5. The support cylinder 1 contains multiple fixing rods 9. A limit plate 8 is fixedly connected to one end of each fixing rod 9. The right end... One side of plate 3 has a first through hole 10 arranged in a ring. The support cylinder 1 is the main skeleton of the entire assembly, which can provide the installation foundation and support for components such as the right end plate 3, the left end plate 2, and the hammer head 6. The connecting hole 4 is the key interface for the installation of the hammer head 6. Through cooperation with the connecting block 5, the hammer head 6 can be positioned and installed. In addition, the high chromium alloy wear-resistant layer on the surface of the hammer head 6 can effectively resist the impact and friction during the material crushing process, significantly extending its service life. The elastic sealing ring between the connecting block 5 and the inner wall of the connecting hole 4 can prevent dust, material particles and other impurities from entering the connection part, avoid wear and loosening of the connection caused by impurities, and ensure the sealing and stability of the connection.

[0020] In this embodiment, as a further solution of the present invention: one end of each fixing rod 9 passes through the first through hole 10 and extends to one side of the first through hole 10. The outer surface of one end of each fixing rod 9 is threaded with a locking nut 11.
