The first motor 4 and the pushing bin 2 are both fixed on the machine platform 1. The first motor 4 drives the auger 3 to rotate. The storage bin 7 is located above the pushing bin 2. The feed pipe 5 is connected to the second motor 10 and the stirring rod 9. The bottom of the storage bin 7 is connected to the feed port of the push bin 2, and the star-shaped discharger 8 is installed on the feed pipe. The star-shaped discharger 8 is an existing commercially available device. The exhaust conveying pipe 6 is an inverted U-shaped pipe. The diameter of the discharge end of the exhaust conveying pipe 6 is smaller than the diameter of its feed end. The feed end of the exhaust conveying pipe 6 is connected to the discharge port of the push bin 2. The installation position of the star-shaped discharger 8 is higher than the highest point of the exhaust conveying pipe 6. A butterfly valve 12 is installed at the discharge end of the exhaust conveying pipe 6. A bag support tube 15 is installed below the butterfly valve 12, and the opening of the bag support tube 15 is downward. The bag-supporting tube 15 is made of iron. A plurality of magnets 16 and a plurality of belts 17 are installed on the bag-supporting tube 15. Each belt 17 corresponds to a magnet 16. The magnets 16 are arranged around the bag-supporting tube 16 at intervals and adsorbed on the surface. One end of the belt 17 is fixedly connected to the surface of the bag-supporting tube 15. The other end of the belt 17 is connected to the magnet 16. The bag-supporting tube 15 is provided with an upper pressing plate 19, a lower pressing plate 20, a connecting rod 18, and a spring 22. The lower pressing plate 20 is located in the bag-supporting tube 15. The lower pressing plate 20 and the bag-supporting tube 15 are connected. The inner surface shapes of the bags are all circular, and a circular discharge hole 21 matching the discharge port of the exhaust conveying pipe 6 is provided on the lower pressure plate 20.

[0016] The working principle of the utility model is as follows: calcium carbonate powder is easy to harden when damp, and the second motor drives the stirring rod to rotate to break up the hardened calcium powder, and then the calcium powder is evenly discharged downward through the star-shaped discharger. The calcium powder moves to the right under the push of the auger, and because the feeding end of the exhaust conveying pipe is higher than the pushing bin, the calcium powder accumulates at the feeding end of the exhaust conveying pipe, and the air in the pushing bin is discharged first. Under the action of gravity and thrust, the air in the accumulated calcium powder is further squeezed out. Since the discharge end of the exhaust conveying pipe has a smaller diameter, the calcium powder is further squeezed out to discharge the air, which reduces the whole conveying speed. The gas content in the material channel ensures the stability of the material feeding amount; the personnel put the packaging bag on the bag supporting tube and use the suction of the magnet to fix the packaging bag on the bag supporting tube. After the material is discharged, the personnel press the upper pressure plate to make the lower pressure plate move downward, flattening the conical pile and pressing the floating calcium powder in the packaging bag, reducing the amount of calcium powder flying and protecting the surrounding environment; after the packaging bag is full, the personnel can quickly move the packaging bag with the assistance of multiple rollers; after packaging, closing the butterfly valve can avoid the problem of calcium powder remaining in the pushing bin coming into contact with air and absorbing water and hardening.
