[0026] Reference Figure 1-5 , wherein the two rotating plates 5 are symmetrically installed inside the feed hopper 2, and the two rotating plates 5 are installed at an angle of one facing upward and the other facing downward;

[0027] With the above-mentioned structural arrangement, when the rotating plate 5 rotates, a gap is always maintained between the two, so that the grain inside the feed hopper 2 always remains in a flowing state to avoid blockage.

[0028] Reference Figure 2-4 , wherein the driving assembly 8 includes a driving motor 81, a driving motor 81 is fixedly installed on one side of the mounting disc 6 away from the feed hopper 2, an output end of the driving motor 81 penetrates and extends to the other side of the mounting disc 6, a transmission rod 82 is fixedly installed on the output end of the driving motor 81, and a limiting block 83 is rotatably installed on the side of the transmission rod 82 facing the feed hopper 2;

[0029] Through the above-mentioned structural arrangement, the driving motor 81 is started, the driving motor 81 drives the transmission rod 82 to rotate on the mounting disc 6, and the transmission rod 82 drives the limit block 83 to rotate.

[0031] Through the above-mentioned structural arrangement, the limiting block 83 drives the transmission frame 7 to move back and forth inside the limiting roller 61 inside the limiting groove 71 as the transmission rod 82 rotates.

[0032] Reference Figure 2-3 , wherein the transmission assembly 9 includes a gear bar 91, the gear bars 91 are fixedly mounted on both ends of the transmission frame 7, a gear 92 meshing with the gear bar 91 is rotatably mounted on the outer side of the feed hopper 2, and the gear 92 is connected to the rotating plate 5 through a connecting shaft;

[0037] The first step to implement the innovation point:

[0038] The first step: after starting the processing, pour the grain into the feed hopper 2, and start the driving motor 81 at the same time. The driving motor 81 drives the transmission rod 82 to rotate on the mounting disc 6, and the transmission rod 82 drives the limit block 83 to rotate.

When the transmission frame 7 moves back and forth, the gear bars 91 on both sides respectively drive the gear 92 to rotate repeatedly as the transmission frame 7 moves. When the gear 92 rotates, it drives the rotating plate 5 to rotate through the connecting shaft, so as to stir the grain inside the feed hopper 2 to avoid clogging of the grain and affecting the operation of the equipment. Finally, the grain falls into the body 1 for processing, and the grain is preliminarily separated into rice husks and brown rice.
