Description

Technical Field

[0001] The utility model relates to the technical field of crusher plate hammers, and more specifically, to a punching plate hammer for a mine crusher. Background Art

[0002] Mining crusher is also known as mining crusher, category: crushing equipment, mining crusher equipment. Stone crushers are widely used in many departments such as mining, smelting, building materials, highways, railways, water conservancy and chemical industries. When mining crushers crush ore, plate hammers are usually used. When in use, the staff needs to install the plate hammer on the rotor body. Since the plate hammer is an integrated structure, it will consume a lot of manpower when installing it, which is not conducive to people's rapid installation or disassembly. The operation is not convenient, it takes a lot of time, and the installation or disassembly efficiency is low, which reduces the convenience of plate hammer installation and use. In addition, the wear-resistant protrusions of the plate hammer will be damaged after working for a long time. Most of the wear-resistant protrusions of the plate hammer are usually directly connected to the plate hammer body as a whole, and cannot be installed and disassembled. When the wear-resistant protrusion is damaged, the plate hammer body can only be replaced as a whole, and the wear-resistant protrusion cannot be directly replaced, which increases the investment cost and the economic burden. For this reason, we have launched the following device. Utility Model Content
