Description
Technical Field
[0001] This utility model relates to the field of jaw crusher technology, and in particular to a jaw crusher with a multi-angle adjustable jaw plate. Background Technology
[0002] Jaw crushers are primary crushing equipment widely used in mining, construction, metallurgy and other fields. They mainly use the periodic movement of the moving jaw and the stationary jaw to squeeze and split materials. The structure consists of a frame, moving jaw, stationary jaw, eccentric shaft and so on. During operation, the motor drives the eccentric shaft to rotate, which drives the moving jaw to move up and down reciprocatingly. When the moving jaw approaches the stationary jaw, the material is squeezed and crushed. When it moves away, the crushed material is discharged from the discharge port. It has the characteristics of simple structure, reliable operation and large crushing ratio. It can meet the needs of coarse crushing operations and is a key piece of equipment in the material crushing production line.
[0003] Currently, in mainstream jaw crushers on the market, the jaw plates composed of the moving jaw and the stationary jaw usually adopt a fixed angle design. This angle is preset according to conventional crushing requirements before the equipment leaves the factory, and it is difficult to adjust conveniently during subsequent use. This fixed angle structural design exposes obvious limitations when dealing with stones of different sizes and hardness. When processing large stones, the fixed jaw plate angle may cause uneven force when the stones enter the crushing chamber, which can easily lead to problems such as material jamming and incomplete crushing. In fact, excessive instantaneous impact force may even cause accelerated wear of equipment parts. When crushing smaller-sized stones, the fixed angle will reduce the effective utilization space of the crushing chamber, and the material will stay in the chamber for too short a time, making it difficult to achieve the ideal crushing particle size. Secondary crushing is required, which increases energy consumption and operation time.
[0004] Therefore, it is necessary to invent a jaw crusher with a multi-angle adjustable jaw plate to solve the above problems. Utility Model Content
