[0018] In specific implementation, when lifting horizontally, the motor 605 drives the transmission shaft 604 to rotate, so that the six sprockets 603 rotate synchronously, so that the four chains 601 are retracted and released at the same speed, so that the connecting plate 502 can always remain horizontal when lifting and lowering, making the whole more stable during filling;

[0019] During filling, the raw materials in the silo 9 flow into the Y-shaped tube 8 through the manual rotary valve 801, and then pass through the pneumatic flow valve 7, and then pass through the soft connection component 3, the inner telescopic mechanism 4, the outer telescopic mechanism 5, and the connecting tube 521 to be filled into the packaging bag. The packaging bag is hung on the bottom of the connecting tube 521 through the pneumatic hook component 503, and is clamped and fixed to the bottom end of the connecting tube 821 through the clamping component 504.
