When the hopper 25 is positioned on the upper side arc surface of the support frame 21, as shown in fig. 4, the stress analysis of the hopper 25 is as follows:
during the discharge process, the material is subjected to its own weight mg and centrifugal force due to circular motion, m omega2r, the reverse extension line of the resultant force N and the central line of the transmission roller in the vertical direction are intersected at a point P, the point P is the pole of the hoister, and the distance h from the pole P to the center of the transmission roller is called as a pole pitch.

Further, as another preferred embodiment, a backflow plate 13 for backflow of the material is disposed below the main housing 1 corresponding to the discharge hole 12.
The working principle of one embodiment of the novel high-speed belt bucket elevator is as follows:
firstly, bulk particles are poured into the bottom of the belt bucket elevator through the feeding hole 11, under the driving action of the driving assembly 26, the bulk particles are loaded into the hopper 25 fixed on the belt 24 due to friction force when the hopper 25 passes through a material pile, and the hopper 25 loaded with the bulk particles ascends along with the belt 24; when passing through the support frame 21, the particles slide along the edge of the hopper 25 under the combined action of centrifugal force and gravity, so that the condition of centrifugal discharging in advance is avoided; when the hopper 25 enters the arc of the upper roller 22, the unloading mode of the material particles is mixed unloading, the material particles in the hopper 25 can be almost completely unloaded, the material backflow phenomenon caused by centrifugal unloading is avoided, and the unloaded bulk material particles leave the belt bucket elevator through the discharge port 12; the hopper 25, which is completely discharged, continues to move downward following the belt 24, ready for the next charge.
Specifically, 1) when the radius of the upper arc surface of the support frame 21 is 3500mm and the diameter of the upper roller 22 is 1800 mm: as shown in the following simulation diagram of fig. 6, at 8.3s the material is discharged from the entire hopper 25, in this case by gravity.
2) When the radius of the upper side arc surface of the support frame 21 is 3500mm, and the diameter of the upper roller 22 is 1400 mm: as shown in fig. 7 to 10, the material is discharged from the entire hopper 25, in this case a combined discharge, and the return flow of material starts to decrease compared to a centrifugal discharge.
Observing the simulation chart, it can be seen that at 3s (as shown in fig. 7), the hopper 25 enters the upper arc surface stage of the support frame 21 from the vertical lifting stage; when t is 7.34s (as shown in fig. 8), the first hopper 25 reaches the first arc-shaped area, and at the moment, the material moves along the sliding surface in the hopper 25, but is not thrown out in advance, so that the problem of premature centrifugal discharge backflow caused by high-speed operation of the belt hopper is effectively solved; after entering the second arc discharge end, when t is 7.72s (as shown in fig. 9), the material starts to be centrifugally discharged through the outer edge of the hopper 25; when t is 7.92s (as shown in fig. 10), the material is fully discharged from the hopper 25, and a large amount of backflow phenomenon is not generated.
