This invention discloses a crusher crushing plate stroke adjustment transmission device, including a frame, a rotor assembly, a crushing plate, and a stroke transmission assembly. The crushing plate includes an upper crushing section and a lower crushing section distributed along the material flow direction, which are connected by a hinge structure. The stroke transmission assembly includes a drive motor, a worm gear reducer, and an adjusting screw. The adjusting screw passes through the frame and is connected to the crushing plate through a ball-end self-aligning connection structure. A guide floating sleeve is provided between the adjusting screw and the frame. When the crushing plate undergoes an angle change during operation, the ball end can generate relative rotation within the self-aligning seat, thereby adapting to and compensating for the angle change. Through the synergistic effect of the above structures, the off-center load on the adjusting screw can be reduced during crushing plate adjustment, improving the operational stability of the adjustment mechanism under impact conditions.
