The invention discloses an automatic bagging device for a photo net cover. The device comprises a bar-shaped sleeve with a V groove sliding way lever, an upper hook claw ring with a lever, a bottle-shaped conical body, a platform with a conical hole, a movable cutter assembly and two power eccentric wheels. Firstly, under the drive of one eccentric wheel, a cover barrel descends to make contact with the conical body; then potatoes slide from a sliding groove of the lever and fall into the sleeve and fall on the upper surface of the conical body, meanwhile, a hook claw hooks the net cover to move upwards under the drive of the other eccentric wheel, the net cover is arranged on the outer surface of the bar-shaped sleeve in a sleeving manner and then moves downwards to reset; then the sleeve moves upwards, and at the moment, the net cover is arranged on the outer surface of the potatoes in a sleeving manner under the action of the self contracting force; and finally, a cutter rotates to cut off the net cover. Circulating is conducted, and automatic net cover sleeving of the potatoes is achieved. The automatic bagging process of round fruits and vegetables such as potatoes is achieved, and a large amount of labor force is saved.
