TECHNICAL FIELD

[0002] In many industries such as construction and mining, excavators often need to be equipped with crushing hoppers to crush various materials, and the size of the discharge port of the crushing hopper is crucial to the efficiency of the crushing operation and the particle size of the crushed materials.
[0003] The crushing hopper is a kind of mine machinery for crushing stone, and its principle is to simulate the movement of the two jaws of an animal by reciprocating swing of the movable jaw plate arranged on the frame and mutual engagement between the movable jaw plate and the fixed jaw plate, so as to crush the materials. The size of the discharge port of the traditional crushing hopper is often fixed, or the adjusting mode is extremely inconvenient. When different hardness and different size requirements of materials need to be processed, the fixed discharge port cannot meet the diversified production requirements. For example, for materials with high hardness and finer crushing requirements, a smaller discharge port is more suitable. For some materials with low requirements on the particle size of the crushed materials, a larger discharge port can improve the crushing efficiency. If the size of the discharge port cannot be adjusted in time and effectively, not only the crushing quality and production efficiency will be affected, but also the equipment may be excessively worn or energy may be wasted.
