The double-groove belt pulley 16 rotates to enable the large belt pulley 21 to rotate through the second flat belt 23, the large belt pulley 21 rotates to drive the projection 22 to rotate, so that the first guide rod 72 can move leftwards through the rotation of the projection 22, the first spring 73 is compressed along with the rotation, when the projection 22 rotates and is not in contact with the first guide rod 72, the first guide rod 72 can move rightwards under the action of the first spring 73, and therefore the first guide rod 72 does not need to be moved leftwards and rightwards by a user, and therefore the workload of the user can be reduced.

The user can place articles on the placing plate 25 without holding the article by hand, and the placing plate 25 can be conveniently held by the user to push the invention to move through the rectangular hole 26, so that the user can conveniently move the invention.

When first slider 78 needs to be moved, the user moves handle 29 upwards, handle 29 moves upwards to enable concave clamping plate 28 to move upwards, fourth spring 27 stretches accordingly, so that fixing of first slider 78 can be relieved, first slider 78 moves to a proper position left and right afterwards, then the user releases handle 29, concave clamping plate 28 can move downwards under the effect of the elastic force of fourth spring 27, so that first slider 78 can be fixed, and therefore when soybeans are screened, inconvenience is brought to soybean screening due to left and right shaking of first slider 78.

The above description is only an example of the present invention and is not intended to limit the present invention. All equivalents which come within the spirit of the invention are therefore intended to be embraced therein. Details not described herein are well within the skill of those in the art.
