Description

Technical Field

[0001] This utility model relates to the field of jaw crusher technology, and more specifically, to a jaw crusher with easily replaceable crushing plates. Background Technology

[0002] Jaw crushers, also known as jaw breakers or tiger mouth crushers, consist of two jaw plates, a moving jaw and a stationary jaw, forming a crushing chamber. They are crushers that mimic the movement of an animal's jaws to complete the crushing operation. They are widely used in the crushing of various ores and large materials in industries such as mining and metallurgy, building materials, highways, railways, water conservancy, and chemicals.

[0003] A search revealed a utility model patent with publication number CN222428071U, which discloses a jaw crusher with easily replaceable jaw plates. The patent includes a frame with a rotating disc fixedly mounted on it. After the first replaceable jaw plate is damaged due to prolonged use, the baffle can be removed by unscrewing the No. 2 bolts at both ends, and then the entire moving jaw plate can be removed by unscrewing the twelve No. 1 bolts. Often, damage to the first replaceable jaw plate occurs in a specific location, making complete disassembly of the first replaceable jaw plate cumbersome. This patent simply removes the baffle, allowing the six locking bolts to slide out of their fixing slots, enabling the removal of all six jaw plate teeth. Only the damaged jaw plate teeth need to be replaced, saving time on disassembling the entire first replaceable jaw plate. During maintenance, only the damaged jaw plate teeth need to be replaced, saving costs and solving the problem of existing devices being unable to easily replace severely worn or damaged parts of the billet, resulting in wasted time and high maintenance costs. However, the aforementioned patent still has the following shortcomings: replacing the crushing plate requires disassembling and assembling multiple bolts, and its convenience needs improvement. Therefore, we propose a jaw crusher with easily replaceable crushing plates. Utility Model Content
