AI Technical Summary
The existing crusher hammers need to be replaced as a whole after they wear out, which increases the cost of equipment use.
The design features a split-type hammerhead that is connected to the hammering surface in parallel via a slide and a plug-in block, and is fixed with a positioning pin. The bushing reduces friction, achieving both stability and detachability of the hammerhead.
The hammer head is less likely to slip out when rotating at high speed, thus avoiding problems such as bolt loosening or pin wear, extending the life of the hammer handle and reducing replacement costs.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of crusher technology, and in particular to a wear-resistant hammer for a split-type crusher. Background Technology
[0002] A crusher is a piece of equipment used for processing metallic and non-metallic minerals. It primarily breaks raw ore into small particles through compression and bending. It is widely used in mining, metallurgy, building materials, highways, railways, water conservancy, and chemical industries.
[0003] During operation, crushers mainly rely on the high-speed rotation of hammers to crush stones. As a result, the hammers are prone to wear during use. Replacing the entire hammer after wear increases the cost of equipment operation. Therefore, a wear-resistant hammer for split-type crushers is proposed. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies where replacing the entire hammerhead after wear increases the cost of equipment use, and to propose a wear-resistant hammerhead for a split-type crusher.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A wear-resistant hammer for a split-type crusher includes a hammer handle and a connecting block integrally formed at the bottom of the hammer handle. Two sides of the connecting block are hammer impact surfaces and the other two sides are side surfaces. Two slide rails are provided at the bottom of the connecting block. The slide rails are located between the two side surfaces and are parallel to the hammer impact surfaces. A hammer head is provided at the bottom of the connecting block. Two plug-in blocks are integrally formed on the surface of the hammer head. The two plug-in blocks are slidably connected to the two slide rails respectively.
[0007] A through mounting hole is provided on one side of the hammer handle;
[0008] A fixing component is disposed on top of the hammer head for fixing the hammer head.
[0009] As a further embodiment of this utility model, the fixing component includes a first countersunk hole, which is opened at the bottom of the hammer handle and extends through the hammer handle. A positioning pin is inserted into the first countersunk hole, and the positioning pin extends through the connecting block and is inserted into the hammer head.
[0010] As a further embodiment of this utility model, a positioning head is fixedly connected to the top of the positioning pin, and the positioning head is located in the first countersunk hole.
[0011] As a further improvement of this utility model, the top of the hammer handle is provided with a through-hole for the positioning pin to pass through.
[0012] As a further improvement of this utility model, a bushing is inserted into the mounting hole.
[0013] As a further embodiment of this utility model, a second countersunk hole is provided on one side of the hammer handle, and a through-hole set screw is threaded into the second countersunk hole. A through-hole is provided on one side of the bushing, and one end of the set screw is located in the through-hole.
[0014] As a further embodiment of this utility model, a rubber plug is bonded inside the second countersunk hole, and one end of the rubber plug is integrally formed with an extension post.
[0015] As a further improvement of this invention, the slide is arranged in a cross shape.
[0016] In this application, during use, the entire unit can be installed by passing the hammer shaft through the bushing inside the crusher. After prolonged use, the hammerhead will wear out. The worn hammerhead can be replaced by pulling out the tapered shaft. During replacement, loosen the set screw, then pull out the bushing, then pull out the locating pin, and then slide the hammerhead to one side to remove it. Replace with a new hammerhead, then reset the locating pin, and observe the wear of the bushing to determine whether to replace the bushing. After all replacements are completed, the equipment can be used. During use, the stability of the hammerhead is maintained by the slide and the plug block. At the same time, because the slide and the plug block are set parallel to the hammer impact surface, the hammerhead can be prevented from slipping out during high-speed rotation. The locating pin is used to fix the hammerhead, which not only ensures the stability of the hammerhead but also prevents the bolt from falling off or the pin from wearing out, thus improving the safety of the equipment. The bushing can prevent friction between the hammer shaft and the hammer handle, thereby increasing the service life of the hammer handle.
[0017] Beneficial effects: In this utility model, the wear-resistant hammer for a split crusher is designed to slide on the bottom of the connecting block. The slide and the plug block are set parallel to the hammering surface, which prevents the hammer from slipping out during high-speed rotation. At the same time, the hammer is fixed by the positioning pin, which not only ensures the stability of the hammer, but also prevents the problems of bolt falling off or pin wear.
[0018] In this utility model, the wear-resistant hammer for a split-type crusher has a bushing installed in the mounting hole, which prevents friction between the hammer shaft and the hammer handle and improves the service life of the hammer handle.
[0019] In this invention, the slide and the plug block are arranged parallel to the hammering surface, which prevents the hammer head from slipping out during high-speed rotation. At the same time, the hammer head is fixed by the positioning pin, which not only ensures the stability of the hammer head, but also prevents the bolt from falling off or the pin from wearing. In addition, the bushing can prevent friction between the hammer shaft and the hammer handle, thereby improving the service life of the hammer handle. Attached Figure Description
