[0045] Due to the design of the No. 1 limit rod 16 and the No. 2 limit rod 18, the vibration of the screen plate 15 will be limited, making it more stable during vibration. Thanks to the design of the No. 1 spring 17 and the No. 2 spring 19, due to their good elastic effect, they will provide a good resetting effect for the screen plate 15.

[0046] A drawer 30 is movably sleeved inside the collection box 3 , and a through slot 26 is provided on the right side of the top of the collection box 3 .

[0047] Due to the design of the drawer 30, large particles of impurities in the grain can be collected.

[0048] A through opening 32 is provided on the right side of the box body 1 , and the interior of the box body 1 is connected with the interior of the collection box 3 through the through opening 32 .

[0049] Due to the design of the through opening 32, large particles of impurities on the top of the sieve plate 15 can enter the interior of the collection box 3 through the through opening 32 and finally fall into the drawer 30 to be collected.

[0050] Among them, a baffle 31 is movably connected to the inner surface of the right side of the box body 1, and the baffle 31 is located on the outside of the right side of the through opening 32. A handle 27 is fixedly installed on the top of the baffle 31, and the top of the handle 27 extends to the top of the top of the collection box 3 through the through groove 26.

[0051] When the handle 27 moves upward, the baffle 31 will be driven upward together, so that large particles of impurities located on the left side of the baffle 31 will fall into the drawer 30 through the opening 32 and be collected. The design of the No. 3 spring 29 will provide a good reset effect for the handle 27 and the baffle 31.

[0052] The working principle and use process of this utility model:

[0053] First, the operator pours the grain into the feeding port 2, and then the grain will enter the interior of the box 1 through the feeding port 2 and finally fall on the top of the sieve plate 15. At this time, the vibration motor 12 is started. When the vibration motor 12 is running, the rotating shaft 13 will drive the vibration block 14 to rotate. Due to the shape design of the vibration block 14, when the vibration block 14 rotates, the sieve plate 15 will vibrate. At this time, the smaller grain will pass through the mesh of the sieve plate 15 and fall to the top of the transmission belt 23, and the large particles of impurities will stay on the top of the sieve plate 15 and finally slide to the left side of the baffle 31.

[0054] Then the operator starts the motion motor 20. When the motion motor 20 is running, the circular shaft 21 will drive the driving gear 22 to rotate. At this time, the driving gear 22 will drive the two driving wheels 24 to rotate through the transmission belt 23. When the driving wheel 24 rotates, it will drive the rubber wheel 25 to rotate. At this time, the rubber wheel 25 will drive the device to move forward at a uniform speed. At the same time, the transmission belt 23 will drive the grain at its top to move to the left. At this time, the operator starts the driving motor 5. When the driving motor 5 is running, the rotating shaft 6 will drive the threaded rod 7 to rotate. When the threaded rod 7 rotates, the motion block 8 will move upward. Then the motion block 8 will drive the motion shaft 10 to move upward through the pull rod 9. When the motion shaft 10 moves upward, it will pull the opening and closing plate 11 to move. At this time, the opening and closing plate 11 will rotate with the hinge with the box body 1 as the axis, so as to achieve the effect of adjusting the opening and closing size. At this time, the grain moving to the left at the top of the transmission belt 23 will be discharged from the inside of the box body 1 through the obstruction of the opening and closing plate 11 for spreading, thereby realizing the function of automatically adjusting the thickness of the spread grain.

[0055] Finally, the operator pulls up the handle 27, and when the handle 27 moves upward, it will drive the baffle 31 to move upward together. At this time, the large particles of impurities on the left side of the baffle 31 will enter the collection box 3 through the opening 32 and finally fall into the drawer 30 to be collected. At this time, the No. 3 spring 29 will be in a compressed state. When the operator releases the handle 27, the elastic force of the No. 3 spring 29 will cause the handle 27 and the baffle 31 to reset.
