Part of the rice passes through the material holes 111 on the aggregate cone hopper 11 and enters the conveying cavity a; at the bottom end of the aggregate cone hopper 11, there are a blocking pipe 71 and a discharge pipe 72. The blocking pipe 71 is installed at the position between the bottom end of the aggregate cone hopper 11 and the discharge pipe 72. The blocking pipe 71 is combined with the bottom end of the aggregate cone hopper 11 and the discharge pipe 72 by conventional methods.

The driving motor 5 drives the first pulley 61 to rotate. The first pulley 61 drives the transmission belt 62 to rotate. The transmission belt 62 drives the second pulley 63, the driving shaft 64, and the rotating cylinder 9 to rotate. The rice materials in the conveying chamber b leak from the meshes on the rotating cylinder 9, achieving the effect of dispersing the rice. Secondly, the rotating cylinder 9 rotates slowly, causing changes in the transported rice, avoiding congestion of the rice, and facilitating the leakage of the rice materials;

[0033] The leaked rice enters the conveying chamber c. The material is shunted and dispersed during transportation in the conveying chamber a, the conveying chamber b inside the rotating cylinder 9, and the conveying chamber c, enabling the material to achieve the effect of shunting and dispersing, and avoiding congestion of the rice materials during transportation;

[0034] In summary: There is a design on the feeding channel opening to shunt the rice and make it in a loose state. The material guiding plate 12 guides the rice. Part of the rice passes through the material holes 111 on the aggregate hopper 11 to achieve partial dispersion. The remaining rice materials enter the interior of the rotating rotating cylinder 9.
