[0008] Furthermore, a sealed bearing cooperating with the rotating shaft is provided in the middle of the bracket to facilitate the rotation operation of the auxiliary rotating shaft.

[0009] Furthermore, a drive box is connected to the top of the first sealing flange, a limit groove is provided inside the drive box and the discharge pipe, a telescopic plate matching the limit groove is connected inside the drive box, and a second electric push rod for driving the telescopic plate to be telescopic is connected to the outside of the drive box, so as to facilitate the material blocking operation in cooperation with the feed auger blades.

[0010] Furthermore, a sealed observation glass is connected to one side of the vacuum feeding tank to facilitate observation of the internal conditions of the vacuum feeding tank.
