[0020] Continue to combine Figure 1 and Figure 2As shown, in this embodiment, a base 4 is included, the movable silo 10 is arranged on the base 4, and the discharge port of the feed cavity is located at the bottom. When the feed cavity is located in the base 4, the discharge port is blocked by the top surface of the base 4. A feeding component is arranged above the movable silo 10, and the feeding component includes a hopper 8 and a connecting portion 9. The connecting portion 9 is suitable for connecting the hopper 8 with the feed cavity. Here, the feed cavity is connected to the top of the movable silo 10. When the movable silo 10 is in the initial position, the feed cavity is connected to the material passage in the connecting portion 9 for feeding, so that the material in the hopper 8 falls into the feed cavity. When the material fills the feeding cavity, feeding cannot continue. When the movable silo 10 moves to the other end relative to the feeding component, the feeding cavity is staggered with the material passage in the connecting portion 9, and the bottom of the material passage is blocked by the top surface of the movable silo 10, so feeding cannot continue. At this time, the discharge port is opened, so that all the material in the feeding cavity falls into the containing vessel 11. Through this solution, it can be ensured that the amount of material falling into the containing vessel 11 is equal each time.

[0021] In this embodiment, the adjusting component includes a push block 1 and an adjusting member, and the adjusting member is suitable for controlling the push block 1 to invade the feed cavity to adjust the volume of the feed cavity, thereby controlling the amount of material in the feed cavity. Specifically, the push block 1 is used to extend into the feed cavity, thereby adjusting the remaining volume in the feed cavity to control the amount of material fed each time; the adjusting member includes a knob 3 and a screw 2, the screw 2 is connected to the push block 1, and the knob 3 is arranged on the screw 2 to drive the push block 1 to move in the feed cavity by rotating the knob 3. In other embodiments, the knob 3 of the adjusting member is connected to a stepper motor to drive the knob 3 to rotate for adjustment, and the control by the stepper motor is more convenient and accurate.

[0022] The driving device 5 is an electromagnetic push rod, and the electromagnetic push rod is connected to the control device 7. The control device 7 is connected to the electromagnetic push rod through a wire 6.
