[0028] The driving structure is arranged in the material box 2 and is used for driving the carrying plate 3 to flip.
[0029] Specifically, the drive structure includes:
[0030] A rotating rod 4 is rotatably mounted in the material box 2 and is located below a pair of carrying plates 3;
[0031] There are two cams 5, both of which are fixedly mounted on the outer surface of the rotating rod 4, and the outer surface of one cam 5 is in sliding contact with the lower wall surface of one bearing plate 3;
[0032] A driving member 6 is provided on the outer wall surface of the material box 2 and is used to drive the rotating rod 4 to rotate;
[0033] The driving member 6 is a low-speed motor. The output end of the driving member 6 is fixedly connected to one end of the rotating rod 4, which can drive the rotating rod 4 to rotate. The rotation of the rotating rod 4 can drive a pair of cams 5 to rotate. When the protruding parts of the pair of cams 5 rotate upward, they can respectively make a pair of supporting plates 3 flip upward and merge, so as to prevent the rice from falling. When the protruding parts rotate downward, under the action of gravity, the supporting plates 3 flip downward to make the rice fall. At this time, the rotation of the cams 5 can make the supporting plates 3 repeatedly flip, so that the rice falls intermittently.
[0034] Specifically, a stirring shaft 7 is rotatably mounted in the material box 2 and above a pair of supporting plates 3, and a plurality of stirring rods 8 are mounted on the outer surface of the stirring shaft 7;
[0035] The plurality of stirring rods 8 are welded on the outer surface of the stirring shaft 7 and can be relatively fixed. The rotation of the stirring shaft 7 can drive the plurality of stirring rods 8 to rotate, so as to stir the rice in the material box 2 and facilitate the rice to fall.
[0036] The ends of the rotating rod 4 and the stirring shaft 7 that are close to each other penetrate the side wall of the material box 2, and are respectively fixed with sprocket wheels 9, and the pair of sprocket wheels 9 are connected to each other by a chain 10;
[0037] The chains 10 are respectively meshed and connected with a pair of sprocket wheels 9 so that they can rotate at the same speed. Under the action of the pair of sprocket wheels 9 and the chains 10, the stirring shaft 7 can rotate at the same speed when the rotating rod 4 rotates.
[0038] Specifically, a pair of vibration motors 11 are symmetrically mounted on the outer surface of the material box 2;
[0039] The vibration motor 11 is fixedly mounted on the outer surface of the material box 2 , and can vibrate the outer wall of the material box 2 to prevent rice from piling up in the material box 2 .

The output end of the driving member 6 can drive the rotating rod 4 to rotate. The rotation of the rotating rod 4 can drive the pair of cams 5 to rotate. When the protruding parts of the pair of cams 5 rotate to the upper side, the pair of supporting plates 3 can be turned upward and merged to prevent the rice from falling. When the protruding parts rotate to the lower side, the supporting plates 3 are turned downward under the action of gravity to make the rice fall. At this time, the rotation of the cam 5 can make the supporting plates 3 repeatedly turn over to make the rice The rice falls intermittently and falls from the feed port into the screening machine body 1, which is convenient for the screening machine body 1 to process the rice. The vibration motor 11 can vibrate the outer wall of the material box 2 to prevent the rice from piling up in the material box 2. At the same time, the rotation of the rotating rod 4 can drive a sprocket 9 to rotate. Under the action of the chain 10, another sprocket 9 can drive the stirring shaft 7 to rotate at the same time. The rotation of the stirring shaft 7 can drive the stirring rod 8 to rotate, so as to stir the rice in the material box 2, prevent the rice from piling up, and make the rice fall more smoothly, bringing convenience to people.
