After the baffle rises, it no longer blocks the through slot, and the polypropylene in the unloading slot enters the interior of the unloading hopper through the through slot. During the rising process of the lifting rod, the storage barrel rises with the lifting rod. After the storage barrel rises, the plug-in rod is plugged into the interior of the arc rod. As the storage barrel moves, the end of the storage barrel swings, so that the two groups of storage barrels are merged together and rise to enter the interior of the unloading hopper.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The cylinder proposed in the present invention drives the lifting rod to rise, and the baffle plate no longer blocks the through slot after rising, and the polypropylene in the lower chute enters the lower hopper through the through slot. After the storage barrel rises, the plug-in rod is plugged into the inside of the arc rod, and the storage barrel moves with the plug-in rod. The two groups of storage barrels are merged together and rise to enter the lower hopper. The two groups of storage barrels are located at the bottom of the lower hopper, and the polypropylene entering the lower hopper falls into the storage barrel, and the storage barrel descends from the inside of the lower hopper. The two groups of storage barrels are separated from each other after descending, and the polypropylene inside the storage barrel falls into the inside of the grinder. The arc rod rises and falls at the same interval, resulting in a stable amount of polypropylene entering the lower hopper, and the separation of the two groups of storage barrels causes the polypropylene to fall, which greatly reduces the blockage of polypropylene.
