A first filter wheel 3 is rotatably installed on the front side of the support platform 2. A second filter wheel 4 is fixedly installed inside the first filter wheel 3. A feeding trough 5 is opened above the second filter wheel 4. A first filter hole 6 is evenly opened on the bottom side of the second filter wheel 4. Slots 8 are opened at the bottoms of both the first filter wheel 3 and the second filter wheel 4. A screening trough 28 is opened on the surface of the first filter wheel 3. A through hole 10 is opened on the front side of the first filter wheel 3. The through hole 10 corresponds to the slot 8. A through hole baffle 11 is movably installed inside the slot 8. A pull ring 12 is fixedly installed on the front side of the through hole baffle 11.

[0027] In this embodiment, when it is necessary to screen wheat grains, first pour the wheat grains into the interior of the second filtering wheel 4 through the feeding trough 5, and then start the servo motor 16 to drive the connecting shaft 24 to drive the first filtering wheel 3 and the second filtering wheel 4 to rotate left and right around the connecting shaft 24, so that normal grains and smaller wheat grains fall into the interior of the screening trough 28 through the first filtering holes 6, and the larger grains remain in the interior of the second filtering wheel 4. Then, screen the fine grains through the second filtering holes 7. After the screening is completed, pull the pull rings 12 at the bottoms of the second filtering wheel 4 and the feeding trough 5 respectively, so that the slots 8 are exposed to collect the wheat grains in the first filtering wheel 3 and the second filtering wheel 4, and thus stack the filtered wheat grains in the interior of the aggregate bin 14.

[0028] Drive the first filtering wheel 3 and the second filtering wheel 4 to rotate left and right through the connecting shaft 24, so that the larger grains remain in the interior of the second filtering wheel 4, and the normal and smaller grains fall into the interior of the first filtering wheel 3. Then, screen the smaller grains through the second filtering holes 7. Pull the pull ring 12 to stack the wheat grains in the interior of the aggregate bin 14. Compared with the traditional screening device for wheat processing, this screening device for wheat processing drives the first filtering wheel 3 and the second filtering wheel 4 to rotate synchronously to screen the wheat grains multiple times, thereby improving the screening efficiency of the wheat grains.

[0029] As Figures 2 to 4 As shown, based on the same concept as the above-mentioned Embodiment 1, this embodiment also proposes that a square groove 15 is opened in the interior of the support platform 2, a disc 18 is rotatably installed in the interior of the square groove 15, a round block 19 is fixedly installed on the outer side of the disc 18, a rectangular plate 20 is movably installed on the outer side of the disc 18, a rectangular groove 21 is opened on the surface of the rectangular plate 20, and the round block 19 is movably connected in the interior of the rectangular groove 21.

The disc 18 drives the round block 19 to rotate. The round block 19 drives the rectangular plate 20 to move left and right. The rectangular plate 20 moving left and right drives the rack 22 to move left and right. The rack 22 moving left and right drives the gear 23 to rotate left and right, so that the connecting shaft 24 rotates left and right to drive the first filtering wheel 3 and the second filtering wheel 4 to rotate synchronously to screen the wheat grains.

[0031] By starting the servo motor 16, the disc 18 rotates. The disc 18 drives the rectangular plate 20 to move left and right through the round block 19, thereby driving the gear 23 to rotate, and the connecting shaft 24 drives the first filtering wheel 3 and the second filtering wheel 4 to move. Compared with the traditional screening device for wheat processing, this screening device for wheat processing drives the gear 23 to rotate left and right by the rotation of the disc 18 to offset the first filtering wheel 3 and the second filtering wheel 4 left and right to screen the wheat grains, improving the screening efficiency of the wheat grains.

[0038] As Figure 2 shown, based on the same concept as in Embodiment 2 above, this embodiment also proposes that a servo motor 16 is fixedly installed on the rear side of the support platform 2. A rotating shaft 17 extending into the square groove 15 is fixedly installed inside the servo motor 16, and the rotating shaft 17 is fixedly connected to the rear side of the disc 18.

[0041] In this embodiment, by installing the fixing block 29 on the outer side of the round block 19, the rectangular plate 20 is limited by the fixing block 29, preventing the rectangular plate 20 from detaching from the round block 19.

[0042] AsFigure 5 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a second filter hole 7 is opened at the bottom of the filter wheel 3, and the radius of the second filter hole 7 is smaller than the radius of the first filter hole 6.

[0043] In this embodiment, the larger and smaller wheat particles are filtered through the filter hole 1 6 and the filter hole 2 7 respectively, which is convenient for use.

[0044] like Figure 1 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a material collecting box 14 is movably installed on the front side of the base 1, and the material collecting box 14 is located below the second filter hole 7.

After the screening is completed, pull the pull rings 12 at the bottom of the filter wheel 2 4 and the feeding trough 5 respectively, so that the slot 8 is exposed to collect the wheat particles in the filter wheel 1 3 and the filter wheel 2 4, and then the filtered wheat particles are stacked in the collecting box 14.
