Firstly, a collecting container is placed below a screening frame 2, an operator pushes a cover plate 4 to move backwards and open through a switch mechanism 9, then crops are poured into the screening frame 2 from a through hole 3, then the cover plate 4 is closed through the switch mechanism 9, then a rotating rod 12 is pulled to rotate anticlockwise to drive a gear 13 to rotate anticlockwise, the gear 13 rotates anticlockwise to drive the screening frame 2 to swing upwards through an arc-shaped rack 14, a first spring 6 is compressed, when the screening frame 2 moves upwards to a proper position, the rotating rod 12 is loosened, the first spring 6 resets, then the screening frame 2 is driven to move downwards, the screening frame 2 moves downwards to drive the gear 13 to rotate clockwise through the arc-shaped rack 14 and reset, the operation is repeated, the screening frame 2 can move upwards and downwards to screen the crops, the screened crops fall into the collecting container, and sundries are left in the screening frame 2, after the crops are screened, the rotating rod 12 is stopped to be pulled, the twisting bolt 21 moves outwards to be separated from the second threaded hole 17 on the right side, then the arc-shaped rod 16 is pulled to move rightwards, the arc-shaped rod 16 moves rightwards to drive the screen plate 10 to move upwards, when the second threaded hole 17 on the left side moves rightwards to the guide block 19, the bolt 21 is twisted into the second threaded hole 17 on the left side, the bolt 21 is matched with the second threaded hole 17 on the left side to fix the arc-shaped rod 16, the screen plate 10 is further fixed, an operator can take out sundries, after the sundries are taken out, the twisting bolt 21 moves outwards to be separated from the second threaded hole 17 on the left side, the arc-shaped rod 16 is pulled to reset, the arc-shaped rod 16 resets to drive the screen plate 10 to reset, and after the arc-shaped rod 16 resets.

Firstly, operating personnel pushes the cover plate 4 to move forwards, the cover plate 4 moves forwards to drive the first rotating rod 92 to rotate reversely, when the cover plate 4 is completely opened, the cover plate 4 stops being pushed, the cover plate 4 is fixed by the first threaded hole 93 and the screw rod 94, at this time, crops are poured into the screening frame 2 from the through hole 3, and after the crops are poured into the screening frame, the cover plate 4 is pulled to move backwards to reset.

At first operating personnel will collect the bag and put in collecting frame 25, and hang the both ends of collecting the bag on couple 28, and then when crops were filtered and dropped, crops drop to in the collecting bag, because of the effect of second spring 24, operating personnel can pull collecting frame 25 horizontal hunting, collecting frame 25 horizontal hunting drives and collects the bag horizontal hunting, it rocks crops to collect the bag horizontal hunting, make crops more level and more smooth, after crops have been screened, will collect bag both ends and take off from couple 28, will collect the bag again and take out and carry out subsequent processing to crops. When the direction of the hook 28 needs to be changed, the hook 28 is pulled to move upwards to drive the fixture block 27 to be separated from the clamping groove 26, the hook 28 can be twisted to rotate to a proper position, and the hook 28 is pushed to move downwards to enable the fixture block 27 to be clamped into the clamping groove 26. So, make things convenient for operating personnel to collect the crops of selecting more.

When screening frame 2 reciprocated and filter crops, pivot 51 positive and negative rotation in turn drove belt pulley 31 positive and negative rotation in turn, and belt pulley 31 drives big belt pulley 29 positive and negative rotation in turn through flat belt 30, and big belt pulley 29 positive and negative rotation in turn drives second bull stick 23 positive and negative rotation in turn, and second bull stick 23 positive and negative rotation in turn drives collection frame 25 horizontal hunting, and then rocks crops level and smooth. After the crops are screened, the screening frame 2 stops moving up and down, the collecting frame 25 stops swinging left and right, and the operator can collect the screened crops. Therefore, the collecting frame 25 does not need to be pulled manually by an operator to swing left and right, and time and labor are saved.

When there is an appropriate amount of crops in screening frame 2, pulling annular bull stick 33 anticlockwise rotation, annular bull stick 33 anticlockwise rotation drives rotary rod 12 anticlockwise rotation through commentaries on classics board 34, and then drive gear 13 anticlockwise rotation, gear 13 anticlockwise rotation drives convex pole 32 anticlockwise rotation, when convex pole 32 anticlockwise rotation contacts with connecting rod 8, can loosen annular bull stick 33, because of first spring 6's effect, screening frame 2 downstream filters crops, and simultaneously, gear 13 clockwise rotation drives convex pole 32 clockwise rotation and resets. In this way, the operator is prevented from rotating the gear 13 counterclockwise to disengage from the arc-shaped rack 14.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
