Figure 4 As shown, when the valve core 19-2 is in the current state, the silo 17 is connected with the cylinder 4 and the inlet end of the discharge pipe 18 is sealed. After the rotary valve coupling 19-3 drives the valve core 19-2 to rotate 90° clockwise, the valve core 19-2 connects the cylinder 4 with the discharge pipe 18. At this time, the discharge port at the bottom of the silo 17 is sealed by the valve core 19-2. Figure 5 After the rotary valve coupling 19-3 drives the valve core 19-2 to rotate 90° counterclockwise, the valve core 19-2 can connect the silo 17 with the cylinder 4 and seal the inlet end of the discharge pipe 18, as shown in FIG.
