A V-shaped guide tube 6 is fixedly connected to the bottom of the feeding pipe 4. A connecting port is provided on the side wall of the feeding pipe 4. A chute 8 is provided in the connecting port. Through the setting of the feeding mechanism, the ferrosilicon fragments can be centrally ground to prevent the material from being scattered.

[0023] A screening trough 2 is provided on the top of the housing 1, a chute 8 is provided in the feeding mechanism, and a screening mechanism is provided in the chute 8. The screening mechanism includes a slider 9 slidably connected to the chute 8, and a screen plate 10 is fixedly connected to the side wall of the slider 9. The end of the screen plate 10 extends to the outside of the feeding pipe 4. A first spring 11 is fixedly connected between the top of the slider 9 and the inner top of the chute 8. Through the setting of the screening mechanism, the thin rope 12 can be driven by the drive of the servo motor 13 to move, and the tension of the first spring 11 can drive the screen plate 10 to vibrate up and down, which is conducive to screening and re-crushing large pieces of ferrosilicon blocks that have been crushed incorrectly;

[0024] The side wall of the shell 1 is provided with a transmission mechanism, the end of the transmission mechanism extends into the chute 8 and is fixedly connected to the bottom of the screening mechanism. The transmission mechanism includes a special-shaped rotating rod 14 rotatably connected to the inner wall of the shell 1, the end of the special-shaped rotating rod 14 is fixedly connected to the second rolling roller 16, the side wall of the special-shaped rotating rod 14 is fixedly connected to the transmission gear 18, and the side wall of the special-shaped rotating rod 14 is rotatably connected to the thin rope 12. The end of the thin rope 12 passes through the feed pipe 4 and extends into the chute 8 and is fixedly connected to the bottom of the slider 9. Through the setting of the transmission mechanism, the thin rope 12 can be driven to move, thereby driving the operation of the screening mechanism;

[0025] A mounting plate and a collecting frame 7 are fixedly mounted on the side wall of the shell 1. A grinding mechanism is provided on the top of the mounting plate. The end of the grinding mechanism is engaged with the end of the transmission mechanism. The grinding mechanism includes a servo motor 13 fixedly mounted on the top of the mounting plate. The end of the output shaft of the servo motor 13 is fixedly connected to the first rolling roller 15. The side wall of the output shaft of the servo motor 13 is fixedly connected to a rotating gear 17. The rotating gear 17 is engaged with the transmission gear 18. Through the setting of the grinding mechanism, the second rolling roller 16 can be driven to rotate in the opposite direction through the engagement of the rotating gear 17 and the transmission gear 18, so that the first rolling roller 15 and the second rolling roller 16 extrude and grind the ferrosilicon fragments.

[0026] The functional principle of this utility model can be explained through the following operation modes:

[0027] In the present invention, when the staff uses the present invention, the staff drives the servo motor 13 to operate and pours the crushed ferrosilicon fragments into the feed funnel 5 through the servo motor 13. The feed funnel 5 will collect the ferrosilicon fragments and drop them between the first rolling roller 15 and the second rolling roller 16 through the feed pipe 4 and the V-shaped conduit 6. The start of the servo motor 13 will drive the rotating gear 17 and the first rolling roller 15 to rotate. The rotation of the rotating gear 17 will drive the transmission gear 18 meshing with it to rotate in the opposite direction, thereby driving the special-shaped rotating rod 14 and the transmission gear 18 to rotate in the opposite direction to the first rolling roller 15. The first rolling roller 15 and the second rolling roller 16 rotate in the opposite direction, which can The ferrosilicon fragments therein are crushed and ground, and the grinding effect is significant. In the process of rotation of the special-shaped rotating rod 14, when the special-shaped rotating rod 14 rotates downward, the special-shaped rotating rod 14 will drive the thin rope 12 to move, and the thin rope 12 will pull the slider 9 and the screen plate 10 to move downward. When the special-shaped rotating rod 14 rotates upward to reset, the slider 9 and the screen plate 10 leave the traction of the thin rope 12 and will be reset by the tension of the first spring 11. The amplitude is small and the frequency is high, thereby repeatedly forming the up and down vibration of the screen plate 10, which can be beneficial to the feeding speed of the ferrosilicon fragments, and guide the large ferrosilicon blocks that have been broken incorrectly to enter the screening trough 2, which is convenient for collection and reprocessing, thereby ensuring the grinding effect of the ferrosilicon blocks of the device.
