[0027] Furthermore, the vibration mechanism includes a rotating groove 25 provided at the bottom end of the support plate 24. The rotating groove 25 is internally connected to a rotating paddle plate 26 that is hit by the falling material. The rotating paddle plate 26 is provided with many rotating plates, and each rotating plate hits the rotating knocking rod 41 once, so that the rotating knocking rod 41 drives the knocking head 42 to knock the vibration plate 23 to cause it to vibrate. A plurality of support sleeve rods 241 are fixedly connected to the side of the support plate 24 close to the vibration plate 23. A pull spring 244 is provided inside the support sleeve rod 241. The pull spring 244 causes the vibration plate 23 that has not been hit to move toward the support plate 24. One end of the sliding rod 242 inserted into the support sleeve rod 241 is fixedly connected to a clamping plate 243 that is stuck in the support sleeve rod 241. The clamping plate 243 prevents the sliding rod 242 from slipping out of the support sleeve rod 241. One end of the support sleeve rod 241 away from the support plate 24 is slidably connected to the sliding rod 242 , and one end of the sliding rod 242 away from the support sleeve rod 241 is fixedly connected to the vibration plate 23 .

[0029] In this embodiment, when it is necessary to use a feeding device for crystallizing aluminum salt material, such as Figure 1 As shown, the material is poured into the feed bin 2 from the top. At this time, the material poured into the feed bin 2 will first slide through the guide plate 21, and finally flow downward through the gap between the guide plate 21 and the inner wall of the feed bin 2. When the material slides downward due to the action of gravity and hits the rotating paddle plate 26, the rotating paddle plate 26 at this time rotates in the rotating groove 25 supported by the support plate 24. The rotating rotating paddle plate 26 after rotation will get stuck in the rotating knocking rod 41. After the rotating paddle plate 26 rotates one circle, the rotating plate on each rotating paddle plate 26 will press against the bottom end of the rotating knocking rod 41 once. The bottom end of the rotating knocking rod 41 that is pressed against will rotate with the support of the U-shaped support 4, and the top end of the rotating knocking rod 41 after rotation will drive the knocking head 42 to rotate. At the same time, the rotating knocking rod 41 will drive the knocking head 42 to return to its original position through the elastic thrust of the reset spring 43, and then the top end of the rotating knocking rod 41 will drive the knocking head 42 to repeatedly knock on the vibration plate 23.

[0030] The vibration plate 23 struck by the knocking plate 41 repeatedly slides horizontally through the support of the plurality of sliding insertion rods 242 and the clamping of the pair of vertical support plates 22. Meanwhile, the clamping plate 243 at the end of the sliding insertion rod 242 is elastically pulled by the pulling spring 244 in the support sleeve rod 241, so that the sliding insertion rod 242 repeatedly slides in the support sleeve rod 241 through the cooperation of the rotating knocking plate 41, and the repeatedly horizontally sliding vibration plate 23 will hit the material between the guide plate 21 and the inner wall of the feeding bin 2, the vibration plate 23 repeatedly hitting the material will continuously disperse the material, so that the material in the bin keeps a loose state, avoids the material from being blocked due to excessive accumulation or excessive viscosity, and thus ensures the smooth flow of the material.
