Feeding device of drying machine

The utility model relates to a feeding device of a drying machine. The feeding device is characterized by comprising a funnel and a conveying tube, wherein the funnel comprises a funnel body and a joining tube which is connected with the funnel body; transition cambered surfaces are arranged at the connecting part of the joining tube and the funnel body; the transition cambered surface comprises a first cambered surface, a second cambered surface and a third cambered surface; the second cambered surface convexes upwards; the first cambered surface and the third concave inwards; the head end of the first cambered surface is connected with the side wall of the funnel in a tangent manner; the tail end of the third cambered surface is connected with the side wall of the joining tube; the conveying tube comprises a head part, a connecting part and a tail part; the head part is connected with the joining tube. The feeding device has the benefits that a conventional manual drying mode is changed, and as glass beads are conveyed into the conveying tube through the funnel, pass through the inner hole of the conveying tube and are conveyed to later drying equipment, automatic feeding is achieved, the working efficiency of feeding is improved, and industrial production can be achieved.
