At this time, since the inter-shaft surface spacing 8 is arranged between adjacent two circular arc panels 7, not only the friction between the shaft surface assembly and the conveying belt 2 is increased, so that the conveying belt 2 can better drive the driven shaft to rotate (if the conveying belt 2 cannot drive the driven shaft to rotate, it will cause the sliding friction between the conveying belt 2 and the driven shaft, and increase the friction loss of the conveying belt 2), but also by using the inter-shaft surface spacing 8, when the material accidentally falls on the driven shaft, part of the material can fall on the shaft body 4 through the inter-shaft surface spacing 8 between the circular arc panels 7, and by using the gradually decreasing feature of the end of the shaft body 4, that is, the slope feature of the conical structure, part of the material slides on the slope of the shaft body 4 to the central shaft 5, and due to the blocking action of the convex ring 6, a barrier protection effect is achieved, which avoids the material from sliding to the conveying support 100, specifically, avoids the material from sliding to the connection between the central shaft 5 and the conveying support 100.
