Detailed Description

The present invention will be further described with reference to the following detailed description. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.

Please refer to fig. 1-4, which are schematic structural views of a preferred embodiment of a feeding mechanism according to the present invention. As shown in the figure: the device comprises a storage bin 1 and an impeller 2; the bottom of the storage bin 1 is connected with a discharge channel 11, and the impeller 2 is driven by a rotary driving mechanism to rotate and is arranged in the discharge channel 11; the impeller 2 comprises a rotating shaft 21 and a plurality of blades 22 connected to the rotating shaft 21, the rotating shaft 21 is arranged at the center of the discharging channel 11, one blade extends outwards from the joint of the rotating shaft 21 and can seal one half of the discharging channel 11, and the other side of the rotating shaft 21 corresponding to the joint of the blade is also provided with the blade which extends outwards and can seal the other half of the discharging channel 11. That is, if the inner cross-section of the discharge channel 11 is a rectangle, the profile of one vane is slightly smaller than half of the rectangular cross-section.
