Description

Technical Field

[0001] The utility model relates to the technical field of crushers, in particular to a jaw crusher. Background Art

[0002] Jaw crushers are widely used in many fields such as mining, smelting, building materials, roads, water conservancy, etc. to crush various materials. Usually, a jaw crusher consists of a moving jaw plate and a static jaw plate to form a crushing chamber, which simulates the movement of the two jaws of animals to complete the crushing operation of materials.

[0003] According to a jaw crusher disclosed in Chinese patent publication number CN 216172562 U, the problem that the current jaw crusher is not convenient to adjust the angle of the movable jaw plate, when there is a crushed stone stuck in the jaw crusher, it is not convenient to take it out, and it is also not convenient to adjust the size of the discharge port. The patent controls multiple first hydraulic cylinders to extend and retract, thereby driving the movable plate, the elastic member, and the slider to extend and retract, so that the slider slides in the slide groove and drives the movable jaw plate to rotate, thereby adjusting the angle of the movable jaw plate; the movable jaw plate drives the slider to vibrate, and the multiple elastic members are extended and retracted at the same time, thereby completing the vibration crushing process of the movable jaw plate; multiple second hydraulic cylinders drive the fixed jaw plate to approach or move away from the movable jaw plate, thereby preliminarily adjusting the size of the discharge port formed between the movable jaw plate and the fixed jaw plate; the fixed jaw plate can be driven away from the movable jaw plate by multiple second hydraulic cylinders, so as to take out the stuck crushed stone; the crusher is not only convenient for adjusting the crushing angle of the movable jaw plate of the jaw crusher, but also convenient for adjusting the size of the discharge port, and convenient for taking out the stuck crushed stone, which is simple and practical and suitable for market promotion. However, when the device is stuck with a stone, the size of the discharge port is adjusted, which easily causes unbroken stone to be mixed with normally crushed stone through the discharge port, making it difficult to distinguish and take out, thereby reducing work efficiency.

[0004] To this end, we proposed a jaw crusher to solve the problem that when the above-mentioned device gets stuck in stones and takes materials, it is easy to cause the crushed and uncrushed gravel to mix, making it inconvenient to distinguish and take, thereby reducing work efficiency.
