Description

Technical Field

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

[0002] The hammer head is one of the core components of a hammer crusher. Attached to the hammer shaft of the crusher's rotor, the hammer head directly strikes the material during high-speed operation, ultimately crushing it to the desired particle size. Crusher hammer heads are categorized by material: high-manganese steel hammer heads, bimetallic hammer heads, composite hammer heads, large gold-tooth hammer heads, medium-chromium alloy hammer heads, and carbide hammer heads. These materials all offer high wear resistance and a long service life.

[0003] However, when the existing hammer head of a crusher is used to crush materials, especially hard materials, the metal on the force-bearing surface of the hammer head will be severely worn and damaged, requiring the entire crushing hammer to be replaced, resulting in the loss of the entire crushing hammer. Therefore, a wear-resistant hammer head for a crusher is proposed. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that the striking head of a wear-resistant hammer is inconvenient to disassemble and replace, and proposes a wear-resistant hammer for a crusher.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A wear-resistant hammer head of a crusher includes a hammer head, a hammer handle and a striking head. The hammer head is fixedly arranged at the lower end of the hammer handle, the striking head is located at the bottom of the hammer head, a plug-in slider is fixedly provided on the top of the striking head, a plug-in slot that matches the plug-in slider is provided at the bottom of the hammer head, and side pressure plates that fix the plug-in slider are detachably provided on both sides of the hammer head.

[0007] Preferably, the bottom of the hammer head is set to an arc-shaped surface, and the striking head adopts an arc-shaped head that matches the bottom of the hammer head.

[0008] Preferably, the plug-in slider adopts a T-shaped block, and the plug-in slide groove adopts a T-shaped groove.

[0009] Preferably, mounting grooves are provided on both sides of the hammer head, the side pressure plates are located inside the mounting grooves and are in contact with the side walls of the plug-in slider, the side walls of the mounting grooves are fixed with screws, and the rod walls of the screws are provided with nuts, and the middle part of the side pressure plates passes through the rod walls of the screws and is fixedly connected by the nuts.

[0010] Preferably, a hammer shaft hole is provided at the upper end of the hammer handle.

[0011] Preferably, the material of the side pressure plate is the same as that of the hammer head and the hammer handle.

[0012] Compared with the prior art, the present invention provides a wear-resistant hammer head for a crusher, which has the following beneficial effects:

[0013] 1. The wear-resistant hammer head of the crusher is connected to the hammer head through the plug-in slider and the plug-in slot. The plug-in slider is inserted into the plug-in slot to connect the strike head to the hammer head. The plug-in slider can be pressed sideways by the side pressure plates on both sides to fix the strike head and the hammer head.

[0014] 2. The wear-resistant hammer head of the crusher is equipped with a screw and a nut. When it is necessary to disassemble and separate the striking head from the hammer head, you only need to loosen the nut with a wrench until the nut is removed from the screw, and then remove the side pressure plate from the inside of the installation groove. At this time, the plug-in slider can be removed from the inside of the plug-in slide, so that the striking head can be disassembled and separated from the hammer head, making it easier to replace the striking head.

[0015] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The utility model adopts a detachable structure for the striking head and the hammer head, which makes the disassembly and replacement of the striking head more convenient and avoids the phenomenon of material loss of the breaker hammer.
