[0031] A positioning frame 4 is arranged at the upper end of the screening plate 2, a matching adjusting plate 5 is penetrated through the positioning frame 4, and a limiting plate 6 is arranged at one side of the upper end of the adjusting plate 5;

[0032] The driving disc 7 is arranged on one side of the feed box 1. A driving rod 8 is provided on one side of the upper end of the driving disc 7. A guide groove adapted to the driving rod 8 is penetrated through the upper end of the screening plate 2. The upper end of the driving rod 8 penetrates the guide groove and is slidably connected to the side wall of the guide groove.

[0033] Specifically, Figure 1 and Figure 3 As shown, both sides of the inner wall of the feed box 1 are penetrated by snap-in grooves, and both sides of the screening plate 2 are provided with snap-in plates 9 adapted to the snap-in grooves. The two snap-in plates 9 are respectively located in the two snap-in grooves and are slidably connected with the side walls of the snap-in grooves. The snap-in grooves on both sides of the inner wall of the feed box 1 cooperate with the snap-in plates 9 on both sides of the screening plate 2 to limit the moving position of the screening plate 2 and prevent its position from shifting when it moves.

[0034] Specifically, Figure 2 As shown, the bottom ends of the two mounting openings are provided with mounting grooves, and the two mounting grooves are rotatably connected with corresponding guide wheels 10. The upper ends of the two guide wheels 10 extend into the two mounting openings respectively, and respectively rest on both sides of the bottom end of the screening plate 2. The two rotatable guide wheels 10 can make the screening plate 2 move more smoothly.

[0035] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, the sieve plate 2 in the feed box 1 is penetrated by a plurality of sieve holes 11 , and the adjustment plate 5 is penetrated by a plurality of adjustment holes 12 matched with the sieve holes 11 , and the plurality of adjustment holes 12 are respectively located at the upper ends of the plurality of sieve holes 11 .

[0036] Through its design, the multiple adjusting holes 12 are driven to move by moving the adjusting plate 5, so that the multiple adjusting holes 12 and the multiple screening holes 11 can be staggered, so that grains of different sizes can be screened and filtered.

[0037] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a fixing plate 13 is provided on one side of the upper end of the screening plate 2, and a threaded rod 14 is rotatably connected to one side of the limiting plate 6. A threaded hole matching the threaded rod 14 is penetrated through the fixing plate 13, and the threaded rod 14 penetrates the threaded hole and is threadedly connected to the side wall of the threaded hole. By rotating the threaded rod 14, the adjusting plate 5 and the limiting plate 6 can be driven to move, thereby driving the multiple adjusting holes 12 to move.

[0038] Specifically, Figure 1 and Figure 2 As shown, a material guide plate 15 is provided on the side wall of the feed box 1 at one end of the screening plate 2. The material guide plate 15 is located at the bottom end of the discharge port 3 and is arranged in an inclined manner. The inclined material guide plate 15 can better discharge the filtered material.

[0039] Specifically, Figure 1 and Figure 2 As shown, a driving motor 16 is provided on one side of the feed box 1 . The driving motor 16 is a prior art and will not be described in detail herein. The output end of the driving motor 16 is provided at the bottom end of the driving disk 7 .

[0040] See also Figure 1-4 When using the feed filtering mechanism to filter the grains, it is first necessary to rotate the threaded rod 14 according to the size of the grains. The threaded rod 14 will drive the limit plate 6 and the adjusting plate 5 to move, and the adjusting plate 5 will drive the multiple adjusting holes 12 to move. By adjusting the spacing between the multiple screening holes 11 and the multiple adjusting holes 12, grains of different sizes can be filtered. When filtering the grains, it is necessary to add the grains to the screening plate 2 in the feed box 1, and then start the driving motor 16. The output end of the driving motor 16 will drive the driving disk 7 to rotate, and the driving disk 7 will drive the driving rod 8 to rotate. In conjunction with the guide groove on one side of the screening plate 2, the screening plate 2 can be reciprocated. Smaller grains will pass through the adjusting holes 12 and the screening holes 11, and larger impurities will be intercepted on the adjusting plate 5 and will be discharged through the discharge port 3 on one side of the feed box 1, thereby effectively filtering the grains.

A limiting spring 18 is sleeved on the outer side of the bottom end of the driving rod 8, and the two ends of the limiting spring 18 are respectively arranged on one side of the screening plate 2 and the limiting ring 17.

[0048] Through its design, the limit ring 17 and the limit spring 18 can limit the position of the drive rod 8 so that it can always be located in the guide groove on one side of the screen plate 2. By moving the drive rod 8 downward, the drive rod 8 is disengaged from the guide groove, so that the screen plate 2 can be disassembled.
