[0037] Example 2:

[0038] See also Figure 1-5 , this embodiment provides a technical solution based on the first embodiment: the auxiliary component 9 includes a carrying plate 14, a transmission shaft 15, a support shaft 16, an eccentric transmission plate 17, a knocking plate 18 and a linkage groove 19, both sides of the bottom of the guide plate 7 are fixedly connected to the carrying plate 14, the two carrying plates 14 are rotatably connected to the transmission shaft 15 and the support shaft 16, one end of the transmission shaft 15 is fixedly connected to the eccentric transmission plate 17, one end of the support shaft 16 is fixedly connected to the knocking plate 18, and the knocking plate 18 is provided with a linkage groove near the end of the transmission shaft 15.

By utilizing the setting of the linkage pin, during the continuous rotation of the eccentric transmission plate 17, the linkage pin can be driven to adaptively move inside the linkage slot 19 to push the knocking plate 18 to knock the bottom end of the guide plate 7 under the support of the support shaft 16.

[0041] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0042] Working principle: First, the raw materials required for the production of NdFeB magnets are poured into the storage hopper 4 and carried by the guide plate 7. Then, the hydraulic cylinder 11 is started to pull the linkage plate 13. Since the linkage plate 13 is located between the hydraulic cylinder 11 and the guide plate 12, the guide plate 12 can be pulled by the linkage plate 13 to drive the guide plate 7 to rotate through the polished rod 6, so that a gap is generated between the guide plate 7 and the bottom of the storage hopper 4. Then, the NdFeB magnet raw materials in the storage hopper 4 can flow out through the gap and be sent to the conveyor body 2 through the guide plate 7. Finally, the raw materials are sent to the production equipment through the conveyor body 2 to achieve loading.

[0043] Subsequently, according to the operation of the production equipment, the size of the gap between the guide plate 7 and the storage hopper 4 is controlled to control the feeding amount of the conveyor body 2. When the NdFeB magnet raw material is blocked in the gap between the guide plate 7 and the storage hopper 4, the drive motor 24 is started to drive the drive shaft 20 to rotate, and the power at the drive shaft 20 is simultaneously transmitted to the two transmission shafts 15 through the synchronous belt 23, so that the transmission shaft 15 drives the eccentric transmission plate 17 to rotate. Under the connection between the eccentric transmission plate 17 and the linkage slot 19, the knocking plate 18 can follow the rotation of the eccentric transmission plate 17 and repeatedly knock the guide plate 7, causing the guide plate 7 to vibrate slightly. The blocked raw material is affected by the vibration and can be sent to the conveyor body 2 through the guide plate 7, so that the conveyor body 2 can be fed smoothly.
