Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0016] Such as Figure 2As shown, an improved feeding structure of a vertical air suction duct comprises a square vertical air suction duct 1, which comprises four side walls, one of which is provided with a notch from the lower end upwards, and an extension plate 4 is provided at the notch in the direction away from the opposite side wall, that is, the extension plate comprises three groups on the front and back. Closing plates 6 are provided at the bottom of the front and back extension plates and the bottom of the four side walls, and a feeding chamber 2 is provided between the extension plates. A vibration motor 5 is provided on the side of the feeding chamber away from the notch, and a feeding port is provided on the upper extension plate of the feeding chamber, and a discharge port is provided on the side of the feeding chamber away from the vibration motor. The lower end of the feeding chamber, close to the vibration motor, is connected to the closing plate through a buffer seat. The feeding chamber can block the notch space formed by the three groups of extension plates and the closing plate. A horizontal positioning rod 7 is arranged on the side wall of the vertical air suction duct with the notch, and a connecting rod 8 is passed through the positioning rod. The connecting rod passes through the upper extension plate 4, and the lower end of the connecting rod is connected to the side wall of the feeding chamber, and the connection method is hinged. A spring 9 is sleeved on the positioning rod, and the spring is arranged between the connecting rod and the side wall of the vertical suction duct with a gap.

[0017] Furthermore, there are two groups of positioning rods and connecting rods, and a baffle 13 is hinged between the two groups of connecting rods. The baffle blocks the discharge port of the feed chamber to ensure uniform material discharge, and the baffle is arranged in the space formed by the extension plate.

[0018] Furthermore, a second connecting rod 10 is inserted through the positioning rod 7, which passes through the upper extension plate and is connected to the side wall of the feed chamber. A second spring 11 is sleeved on the positioning rod and arranged between the connecting rod and the second connecting rod. The upper extension plate has a fixing hole for the connecting rod and the second connecting rod to pass through, and the fixing hole is larger than the diameter of the connecting rod and the second connecting rod.

[0019] The end of the positioning rod is provided with a thread, and a nut 12 is provided at the thread, and the nut abuts against the second connecting rod. Relative positioning is achieved by the nut to ensure buffering when the feed chamber vibrates.

During the vibration process of the feed chamber, due to the limitation of the connecting rod and the second connecting rod, the problem of the feed chamber tilting affecting the material feeding will not occur. At the same time, there can also be a certain buffer to ensure the stability of the overall structure. When the material is discharged to the sealing plate, i.e., the bottom plate, of the vertical suction duct, the upper end of the suction duct is connected to the air separation structure to absorb and collect smaller particle impurities for treatment.
