A drive pulley is fixedly installed on the drive shaft end of the first drive motor 3. A transmission belt 6 is installed on the upper part of the drive pulley and the transmission pulley 5.

[0026] The feeding mechanism is used for feeding the crushing mechanism. The feeding mechanism includes a feeding bin 8, a second drive motor 9, a vibrating feeding plate 10, and a vibrator 11. The feeding bin 8 is driven by the second drive motor 9 to rotate and is installed at the rear of the crusher base 1. Specifically, see attached... Figure 2 As shown, in order to support the feeding hopper seat 8, a support shaft is rotatably mounted on the upper part of the rear support of the crusher base 1. The support shaft is fixedly connected to the bearing seat provided on the lower front side of the feeding hopper seat 8. The feeding hopper seat 8 is supported by the support shaft and rotated on the rear of the crusher base 1. The second drive motor 9 is used to drive the rotation of the feeding hopper seat 8, as shown in the attached diagram. Figure 3 As shown, to improve transmission stability, a reducer is provided on the drive side of the second drive motor 9. The reducer is fixedly installed on the rear side of the crusher base 1 by a bracket. The drive shaft end of the second drive motor 9 is fixedly installed with the input shaft end of the reducer. A toothed drive wheel is fixedly installed on the output shaft end of the reducer. A toothed transmission wheel 13 is fixedly installed on the end of the support shaft. A transmission toothed belt 12 is installed on the upper part of the toothed drive wheel and the toothed transmission wheel 13. A tipping feeding working structure is adopted. A feeding bin seat 8 is provided at the rear of the crusher base 1. The feeding bin seat 8 is driven by the second drive motor 9 to tilt. During operation, the upward tilting can replace manual lifting and feeding of crushed stone materials. The structure is simple and the operation is reliable. While saving manpower, it can effectively improve the processing efficiency of the device. The transmission toothed belt 12 is a high-strength toothed belt and is set in multiple sets. The toothed belt drive can ensure the stability of the tilting drive of the feeding bin seat 8.

[0027] The vibrating feed plate 10 is driven by a vibrator 11 and is floatingly mounted in the middle of the feeding bin base 8, as shown in the attached diagram. Figure 3As shown, to facilitate the connection and installation of the vibrating feed plate 10, a material plate mounting groove is provided in the middle of the feeding bin base 8. The vibrating feed plate 10 is movably fitted into the inner side of the material plate mounting groove. To achieve floating installation, a limiting guide post 14 and a spring 15 for floating support installation of the vibrating feed plate 10 are provided in the middle of the feeding bin base 8, as shown in the attached figure. Figure 5 As shown, the limiting guide posts 14 are uniformly and fixedly installed on the lower part of the vibrating feed plate 10. The limiting guide posts 14 are movably inserted into the guide holes in the material plate mounting groove. The end of the limiting guide post 14 is provided with a limiting end seat. The spring 15 is installed between the feeding bin seat 8 and the vibrating feed plate 10. The vibrator 11 is a fixed eccentric vibration generator in the prior art. The vibrator 11 consists of a dual-axis motor and two sets of eccentric counterweights. The dual-axis motor drives the two sets of eccentric counterweights to rotate, and vibration is generated by the eccentric effect. 1. The vibrators are installed in pairs, with two sets of vibrators 11 bolted to the sides of the middle of the vibrating feed plate 10. Limiting guide posts 14 and springs 15 provide floating support for the vibrating feed plate 10. During feeding, the vibration of the vibrators 11 drives the vibrating feed plate 10 to move up and down at high speed in the middle of the feeding bin 8. Vibration assistance ensures smooth and stable material feeding within the feeding bin 8, greatly improving the stability of the device. To protect the vibrators 11, as shown in the attached... Figure 3 As shown, a protective cover 16 is fixedly installed on the outside of the vibrator 11. The protective cover 16 is a metal cover, and the sides of the protective cover 16 are set with slopes to ensure smooth material feeding.

[0028] Working principle or structural principle: During operation, when feeding materials, the feeding hopper 8 is positioned as shown in the attached figure. Figure 1 In the working state shown, material is filled into the lower hopper of the feeding bin 8. Then, the second drive motor 9 operates, driving the feeding bin 8 upwards via the transmission belt 12 and the toothed drive wheel 13, so that the feeding bin 8 is in the position shown. Figure 2In the working state shown, the material in the hopper of the inclined feeding bin 8 moves downward under the guidance of the inclined plane. At the same time, the vibrators 11 on both sides of the upper part of the vibrating feeding plate 10 work to drive the eccentric counterweights on both sides to rotate synchronously through the motor. The eccentric vibration drives the vibrating feeding plate 10 to vibrate rapidly. The vibration assistance can ensure the smooth and stable downward movement of the material in the feeding bin 8, so that the material enters the hopper of the upper part of the crusher base 1 stably. The eccentric shaft in the crusher base 1 is driven by the first drive motor 3 to rotate, and then drives the moving jaw plate 2 to perform periodic reciprocating motion through the thrust plate. When the moving jaw plate 2 approaches the stationary jaw plate 4, the "V"-shaped crushing chamber formed by the two gradually shrinks. The material is squeezed and crushed into small pieces by the pressure of the moving jaw plate 2 and the stationary jaw plate 4. When the moving jaw plate 2 leaves the stationary jaw plate 4, a certain space is formed at the bottom of the crushing chamber. The material that has been crushed to the qualified particle size is discharged through the discharge port under the action of gravity, completing the crushing work.

[0029] In summary, this crusher adopts a tipping-type feeding structure. A feeding bin seat 8 is set at the rear of the crusher base 1. The feeding bin seat 8 is driven by the second drive motor 9 to tilt. During operation, the upward tilting motion can replace manual lifting and feeding of crushed stone materials. The structure is simple and reliable. While saving manpower, it can effectively improve the processing efficiency of the device. In addition, a floating feeding auxiliary structure is adopted. The limiting guide column 14 and the spring 15 are used to float and support the vibrating feeding plate 10. During the feeding operation, the vibration drive of the vibrator 11 can make the vibrating feeding plate 10 float up and down at high speed in the middle of the feeding bin seat 8. The vibration assistance can ensure the smoothness and stability of the material feeding in the feeding bin seat 8, which greatly improves the working stability of the device.
