technical field

The invention relates to the technical field of feed screw conveyors, in particular to a screw conveyor capable of quickly feeding and discharging feed.

Background technique

The force that makes the material not rotate with the screw conveyor blade is the weight of the material itself and the impact of the screw conveyor casing on the material. frictional resistance. At present, the screw feeder has been widely used in the production process of fine powder and ultrafine powder in the feed industry, and the fine powder and ultrafine powder are quantitatively and continuously fed from the storage bin or hopper to the receiving device. go. In poultry farming, it is generally necessary to use a screw conveyor to transport granular feed to different breeding circles for feeding.

When the existing screw conveyors transport poultry feed, most of them use the gravity of the feed itself to fall into the feeding end of the conveyor for feeding operation, and the output end is directly discharged to the outside by the thrust of the screw blade for feeding. Hey, this way of feeding and discharging the material is slow, and the feed is easy to get stuck when it enters the input end, which affects the efficiency of the input. At the same time, the thrust of the screw blade is limited, so that the discharge speed of the feed is slow, and the feed is accumulated at the outlet. , It is not conducive to large-scale scattered feeding in the breeding circle. For this reason, we propose a kind of screw conveyer that can realize the fast feeding and discharging of feed.
