However, when the half gear is meshed with the column gear, the half gear rotates one circle and the meshing column gear rotates half a circle, so that the partition pauses between moving up and down, and the rice can be evenly divided into small piles with spacing between them, thereby achieving quantitative screening and avoiding excessive screening to affect the screening effect, thereby ensuring the quality of rice.

[0031] In this embodiment, two groups of baffle plates 25 are provided on the surface of the conveyor belt 24, and the upper ends of the two groups of baffle plates 25 are fixedly connected to the first connecting shell 21, and the rear ends of the two groups of baffle plates 25 are fixedly connected to baffle plates 26. Both sides of the conveyor belt 24 are fixedly connected to connecting belts 27, and the outer sides of the connecting belts 27 are fixedly connected to multiple groups of evenly arranged protrusions 28. The upper end of the first connecting shell 21 is fixedly connected to a feed trough 214, and the lower end of the feed trough 214 is fixedly connected to a smoothing plate 215.

[0032] Specifically, after the rice is poured into the first connecting shell 21, a relatively large pile will be formed on the conveyor belt 24.

[0034] Specifically, under the meshing of the half gear 211 and the column gear 212 and the connection of the belt 34, the cam 35 rotates together with the rotating rod 32. As the cam 35 rotates, the connecting frame 36 moves up and down with it, thereby linking the partition plate 37 to move up and down.

[0035] In this embodiment, a cam 35 is fixedly connected to the outer side of the rotating rod 32, and a connecting frame 36 is movably connected to the outer side of the cam 35. The lower end of the connecting frame 36 is fixedly connected to the partition 37, and the front and rear ends of the connecting frame 36 are both slidably connected to the limiting plates 38. The lower ends of the two sets of limiting plates 38 are fixedly connected to the first connecting shell 21.

[0036] Specifically, the half gear 211 is meshed with the column gear 212. After the half gear 211 rotates one circle, it can mesh with the column gear 212 and rotate half a circle, so that the partition 37 pauses between moving up and down, and the rice is evenly divided into small piles with spacing between them, thereby achieving quantitative screening and avoiding excessive screening that affects the screening effect.

[0037] In this embodiment, the first screening mechanism 7 includes a connecting plate 1 71, a sieve plate 1 72 is fixedly connected to the rear end of the connecting plate 1 71, a sieve plate 2 73 is fixedly connected to the upper end of the sieve plate 1 72, baffle plates 3 74 are fixedly connected to both sides of the upper end of the sieve plate 1 72, baffle plates 3 74 are fixedly connected to both sides of the sieve plate 2 73, connecting plates 2 75 are fixedly connected to both sides of the sieve plate 1 72, a spring 76 is fixedly connected to the lower end of the connecting plate 2 75, the lower end of the spring 76 is fixedly connected to the inner wall of the second connecting shell 5, a rotating block 77 is fixedly connected to one side of the connecting plate 2 75, and the rotating block 77 is rotatably connected to the second connecting shell 5.

[0038] Specifically, the rice will be screened by the sieve plate 1 72 and the sieve plate 2 73 and fall uniformly onto the inner side of the connecting plate 3 88 , while larger particles of stone and other impurities will remain on the sieve plate 1 72 . In addition, when the connecting belt 27 is transported along with the conveyor belt 1 24 , it will drive multiple groups of protrusions 28 to operate together, and the protrusions 28 will move the connecting plate 1 71 to generate vibration when moving.

[0039] In this embodiment, the second screening mechanism 8 includes a mounting plate 1 81 and a mounting plate 2 82. The opposite sides of the mounting plates 1 81 and 82 are fixedly connected to the second connecting shell 5. Fans 83 are provided on the inner sides of the mounting plates 1 81 and 82. A rotating plate 84 is connected between the mounting plates 1 81 and 82 for rotation. A motor 2 85 is installed at the rear end of the mounting plate 2 82, and the output end of the motor 2 85 is fixedly connected to the rotating plate 84.

[0040] Specifically, the motor 2 85 drives the rotating plate 84 to rotate, and the fan 83 starts to blow air, and the connecting plate 3 88 carries the rice after the first screening and starts to move clockwise on the inner side of the second connecting shell 5 along with the rotating plate 84. Since the front end of the connecting plate 3 88 is in contact with the inner wall of the second connecting shell 5, when the connecting plate 3 88 moves to the bottom of the sieve plate 1 72, as the original path runs, the sieve plate 1 72 will be moved, and the sieve plate 1 72 and the sieve plate 2 73 will be moved as a whole to the other side, so that the impurities screened out on the sieve plate 1 72 fall into the impurity groove 1 4 for collection, and then the sieve plate 1 72 is pulled back to its original position by the spring 76.

[0041] In this embodiment, a plurality of connecting rods 86 are fixedly connected to the outer side of the rotating plate 84, one end of the connecting rod 86 is fixedly connected to a ventilation plate 87, the front end of the ventilation plate 87 is fixedly connected to a connecting plate three 88, the front end of the connecting plate three 88 is in contact with the inner wall of the second connecting shell 5, baffle four 89 are fixedly connected to both sides of the connecting plate three 88, and a support ear 810 is provided at the upper end of the ventilation plate 87.

[0042] Specifically, when the connecting plate three 88 carrying the rice rotates to the upper side and starts to move downward, the rice and the rice husk fragments contained therein on the connecting plate three 88 begin to fall downward as the support ear 810 tilts. During the falling process, the rice husk fragments contained in the rice are blown into the impurity tank two 10 by the wind for collection, thereby removing the rice husk fragments.

[0043] In this embodiment, an opening 9 is provided on the surface of the second connecting shell 5, and the opening 9 is connected to the impurity groove 10. A discharge port 11 is provided on the surface of the second connecting shell 5. Two groups of mutually symmetrical support plates 12 are fixedly connected to the lower end of the second connecting shell 5. A conveyor belt 13 is movably connected between the two groups of support plates 12, and the conveyor belt 13 is located below the discharge port 11.

[0044] Specifically, the rice with impurities removed slides along the inner wall of the second connecting shell 5 to the discharge port 11, and the discharge port 11 falls uniformly onto the second conveyor belt 13, and then is uniformly transported to the receiving trough 14 through the second conveyor belt 13, completing the screening of rice impurities and facilitating the subsequent processing and production of rice.

[0045] When in use, place the support frame 1 on a horizontal ground, start the motor 210, the motor 210 drives the second roller 23 to rotate clockwise, so that the conveyor belt 24 starts to operate, and the rice containing impurities is poured from the feed trough 214 into the first connecting shell 21. After being poured, the rice will fall on the conveyor belt 24 and be transmitted through the conveyor belt 24. First, after the rice is poured into the first connecting shell 21, a large pile of accumulation will be formed on the conveyor belt 24. Then, in the process of transportation with the conveyor belt 24, the smoothing plate 215 is set to smooth the rice during transportation, so as to avoid blockage during transportation. At this time, under the meshing of the gears and the connection of the belt 34, the cam 35 moves along The connecting frame 36 moves up and down with the rotation of the cam 35, so that the partition plate 37 moves up and down, and meshes with the column gear 212 through the half gear 211. After the half gear 211 rotates one circle, it can mesh with the column gear 212 and rotate half a circle, so that the partition plate 37 pauses between moving up and down, and the rice is evenly divided into small piles with spacing between them. When the rice reaches the rear end of the conveyor belt 24, it will be transferred to the sieve plate 1 72 through the connecting plate 1 71, and then the rice will be screened by the sieve plate 1 72 and the sieve plate 2 73, and fall uniformly on the inner side of the connecting plate 3 88. Larger particles of stone and other impurities will stay on the sieve plate 1 72. When the connecting belt 27 is transported with the conveyor belt 24, it will drive multiple groups of protrusions 28 to operate together. When the protrusions 28 move, they will move the connecting plate 71, and under the connection of the spring 76 and the rotating block 77, the connecting plate 71 will vibrate regularly to promote the smooth screening of rice. After the rice falls on the connecting plate 3 88, the motor 2 85 drives the rotating plate 84 to rotate, and the fan 83 starts to blow air. The connecting plate 3 88 carries the rice after the first screening and starts to move clockwise on the inner side of the second connecting shell 5 along with the rotating plate 84. Since the front end of the connecting plate 3 88 is in contact with the inner wall of the second connecting shell 5, when the connecting plate 3 88 moves to the bottom of the sieve plate 72, along with the operation of the original path, the rice is sifted. When the sieve plate 1 72 rotates, the sieve plate 1 72 and the sieve plate 2 73 are tilted to the other side as a whole, so that the impurities sieved out of the sieve plate 1 72 fall into the impurity groove 1 4 for collection, and then the sieve plate 1 72 is pulled back to its original position by the spring 76, and the connecting plate 3 88 continues to move with the rice. When it rotates to the upper side and starts to move downward, the rice and the rice husk fragments contained therein on the connecting plate 3 88 begin to fall downward as the support ear 810 tilts. In the process of falling, the rice husk fragments contained in the rice are blown into the impurity groove 2 10 by the wind for collection, and the rice with impurities removed falls onto the conveyor belt 2 13 through the discharge port 11 and is uniformly collected on the inner side of the receiving groove 14.
