A weight sensor 25 is installed at the bottom inside the crushing chamber 14. One side of the bottom of the crushing chamber 14 is connected with the discharge port 12. When the crushed stones are concentrated at the bottom inside the crushing chamber 14, after the weight sensor 25 senses the gravity of the materials, the signal is transmitted to the control device. The control device is used to control the second rotation driving mechanism 18 to drive the screw rod 23 to rotate. While rotating, the moving cylinder 21 is made to linearly move along the screw rod 23 by the guiding action of the limiting sliders 20 sliding along the limiting sliding grooves 22, and the feeding push plate 24 can be pushed to act to push the stones at the bottom inside the crushing chamber 14 towards the area of the discharge port 12, and the stones can be pushed onto the conveying device established on the side of the discharge port 12.
