Description

Technical Field

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

[0002] A jaw crusher consists of a frame, a driving motor, a moving jaw, a stationary jaw, etc. During the working process of the jaw crusher, the motor drives the pulley, and the pulley drives the eccentric shaft. During the rotation of the eccentric shaft, the moving jaw can move. In this way, the distance between the moving jaw and the stationary jaw will sometimes become larger and sometimes smaller. When the distance becomes larger, the crushing cavity becomes larger, and the material will sink due to the action of gravity. At this time, the distance between the moving jaw and the stationary jaw becomes smaller again, and the material is squeezed and broken. After extrusion, the moving jaw moves away, and the distance between the moving jaw and the stationary jaw increases. The crushed material just falls downward from the discharge port due to the action of gravity to complete the crushing process. Among them, the double-toggle jaw crusher is a relatively important one.

[0003] In order to improve the utilization rate of the jaw plates, the existing double-toggle jaw crushers often adopt segmented jaw plates. The stationary jaw plate and the moving jaw plate are respectively composed of two jaw plates and two limiting plates, and then the jaw plates are fixed to the machine body by a plurality of screws. However, this fixing method requires turning a large number of screws and a large number of turns when installing or adjusting the jaw plates, which is time-consuming and laborious.

Then, the jaw plate drives the T-shaped strip to slide down, and then the spring releases to push the L-shaped block to slide back in the opposite direction. The outer wall of the L-shaped block and the inner wall of the L-shaped groove restrict the upward sliding of the T-shaped strip, thereby locking the jaw plate. When it is necessary to unlock the jaw plate, only the sliding plate needs to be slid, so that the vertical rod drives the horizontal rod, and the horizontal rod drives the L-shaped block to slide away from the top of the T-shaped strip, enabling the T-shaped strip to slide upward, so that it can be taken out for rotation or replacement. Through the cooperation of the above parts, the method of fixing with multiple screws is replaced, simplifying the operations of installation and removal, thereby saving time and effort.
