One end of 22 is rotatably connected to one side of the screen plate 5. A rectangular groove 21 is provided inside the screen plate 5. A sliding plate 23 is slidably connected to the inner wall of the rectangular groove 21. A plurality of through holes 24 are provided on the outer surface of the sliding plate 23. The diameter of the through holes 24 is the same as the diameter of the sieve hole 6. A slot block 25 is fixedly connected to one side of the top of the sliding plate 23. The inner wall of the slot block 25 is threadedly connected to the outer surface of the screw 22. By setting the sliding plate 23, when the screening device is used, corn kernels are poured into the surface of the screen plate 5, and the vibrating electric motor on one side of the operating frame 1 is operated. The machine 4 drives the screen plate 5 to vibrate so that the corn kernels move on the surface of the screen plate 5 toward the output trough 8. The vibration of the screen plate 5 causes the corn kernels to pass through the sieve holes 6 and enter the output trough 8 below the screen plate 5. The debris will be discharged through the miscellaneous discharge trough 7. When the debris and corn kernels enter the output trough 8, the debris will pass through the fine screen and enter the crushing trough 9 for output. When screening corn kernels of different particle sizes, the screw 22 can be rotated to control the slot block 25 to move on the outer surface of the screw 22 to drive the sliding plate 23 to slide on the inner wall of the rectangular slot 21. The sliding plate 23 can be adjusted. The position of the screen holes 6 on the surface of the screen plate 5 and the through holes 24 on the surface of the sliding plate 23 are changed in the rectangular groove 21, and the interval size of the screen holes 6 is adjusted to screen corn kernels of different particle sizes. By providing the adjustment device 2, the relative position between the sliding plate 23 and the screen plate 5 can be adjusted by rotating the screw 22 to control the movement of the sliding plate 23 in the rectangular groove 21, thereby changing the screening interval size of the screen holes 6 to screen corn kernels of different particle sizes, thereby improving the flexibility and practicality of the screening device.
[0029] Reference Figure 2-3As shown, in this embodiment: positioning grooves 27 are respectively provided on both sides of the inner wall of the rectangular groove 21, and positioning rods 26 are fixedly connected to both sides of the sliding plate 23. The outer surfaces of the positioning rods 26 slide on the inner walls of the positioning grooves 27. When the screw 22 is rotated to control the sliding plate 23 to slide on the inner wall of the rectangular groove 21, the positioning rods 26 on both sides of the sliding plate 23 will slide on the inner walls of the positioning grooves 27, further limiting the angle between the sliding plate 23 and the rectangular groove 21 to avoid the angle of the sliding plate 23 from deflecting as much as possible. A sealing piece 29 is fixedly connected to one side of the screen plate 5. The sealing piece 29 is made of rubber material. The sealing piece 29 is located above the rectangular groove 21. By setting the rubber sealing piece 29, the contact point between the top of the sliding plate 23 and the top of the inner wall of the rectangular groove 21 can be further sealed, so as to avoid corn kernels or corn debris from entering the interior of the rectangular groove 21 through the gap between the sliding plate 23 and the rectangular groove 21, affecting the normal movement of the sliding plate 23.

By holding the protrusions on the outer surface of the operating block 28, the operating block 28 can be rotated more conveniently to control the rotation of the screw 22 without slipping.
[0031] Reference Figure 1 、 Figure 2 and Figure 4 As shown, in this embodiment: a guide device 3 is provided at one end of the crushing trough 9, and the guide device 3 includes two rectangular blocks 31. The top of the rectangular block 31 is fixedly connected to one side of the bottom end of the crushing trough 9. The two rectangular blocks 31 are rotatably connected to a rotating shaft 32 on one side close to each other. The outer surface of the rotating shaft 32 is fixedly connected to a guide plate 33. One end of the rotating shaft 32 is threadedly connected to a threaded ring 36. One side of the threaded ring 36 is rotatably connected to a circular ring 35. One side of the circular ring 35 is fixedly connected to an insertion rod 37. A plurality of insertion holes 34 are opened on the outer surface of a rectangular block 31. When using the screening device, the guide plate 33 can be pushed to rotate the shaft 32 to adjust the angle between the guide plate 33 and the crushing trough 9, and then the threaded ring 36 can be rotated to make the threaded ring 36 move on the outer surface of the shaft 32 to push the circular ring 35 to insert the insertion rod 37 on one side of the circular ring 35 into the socket 34 on the outer surface of the rectangular block 31 to fix the angle between the guide plate 33 and the crushing trough 9. By adjusting the angle of the guide plate 33, it is convenient to adjust the angle and position of the debris output through the crushing trough 9 and the guide plate 33, so as to facilitate the placement of debris receiving containers of different specifications.
[0032] Reference Figure 2 and Figure 4The end of the rod 37 that is provided with the rubber round sleeve 38 is fixedly connected to the inner wall of the rod 37 when the rod 37 is inserted into the inside of the insertion hole 34, so that the angle between the guide plate 33 and the crushing trough 9 is not easy to shake after the angle between the guide plate 33 and the crushing trough 9 is fixed. The end of the rotating shaft 32 away from the rectangular block 31 is fixedly connected to the stopper 39. The length of the stopper 39 is greater than the diameter of the rotating shaft 32. By setting the stopper 39, the movement range of the threaded ring 36 on the outer surface of the rotating shaft 32 can be limited. As far as possible, the threaded ring 36 can be prevented from falling off the surface of the rotating shaft 32 and being lost when the threaded ring 36 is moved outward. The outer surface of the stopper 39 is provided with two grooves 310, and the two grooves 310 are respectively located on both sides of the stopper 39. The two grooves 310 on the outer surface of the stopper 39 can be pinched at the two grooves 310 on the outer surface of the stopper 39 to more conveniently control the rotation of the rotating shaft 32 to adjust the angle of the guide plate 33.
[0033] Working principle: When using the screening device, you can first push the guide plate 33 on one side of the crushing trough 9 to adjust the angle between the guide plate 33 and the crushing trough 9 by rotating the rotating shaft 32, then rotate the threaded ring 36 to make the threaded ring 36 move on the outer surface of the rotating shaft 32, push the circular ring 35, and insert the insertion rod 37 on one side of the circular ring 35 into the socket 34 on the outer surface of the rectangular block 31 to fix the angle between the guide plate 33 and the crushing trough 9, adjust the angle of the guide plate 33, and then place the debris receiving container under the guide plate 33, pour the corn kernels onto the surface of the screen plate 5, and operate the vibration motor 4 on one side of the frame 1 to drive the screen plate 5 to vibrate so that the corn kernels move on the surface of the screen plate 5 toward the output trough 8. The vibration of the screen plate 5 will cause the corn kernels to pass through the screen holes 6 and enter the output slot 8 below the screen plate 5, and the debris will be discharged through the miscellaneous outlet slot 7. When the debris and corn kernels enter the output slot 8, the debris will pass through the fine screen into the crushing slot 9 and be output into the collection container through the guide plate 33. When it is necessary to screen corn kernels of different particle sizes, the screw 22 is rotated to control the slot block 25 to move on the outer surface of the screw 22, driving the sliding plate 23 to slide on the inner wall of the rectangular slot 21, adjusting the position of the sliding plate 23 inside the rectangular slot 21, changing the relative position of the screen holes 6 on the surface of the screen plate 5 and the through holes 24 on the surface of the sliding plate 23, and adjusting the interval size of the screen holes 6 to screen corn kernels of different particle sizes.
