The thickness that the aforesaid structure made the material on the sorting bed 30 is more even through setting a plurality of bed sections of sorting bed 30 to different inclination to has promoted sorting facilities's separation effect.

In addition, above-mentioned mode of setting up can also promote sorting facilities's separation efficiency, specifically: the wide-angle design of the feeding bed section ensures that the bed layer can not be pressed at the feeding end to be dead. The multi-angle sorting bed reduces the retention time of the easily-sorted materials on the upper layer in the equipment, prolongs the retention time of the difficultly-sorted materials on the bottom layer in the equipment, and enables the difference of the layering time of the materials with different layer heights in the equipment to correspond to the retention time of the materials with different layer heights in the equipment. In addition, the sorting bed is arranged in a variable angle mode, the thickness of the bed layer in the sorting bed is basically the same, and the utilization space of the sorting bed is improved.

It should be noted that the predetermined direction refers to a moving direction of the material (as indicated by an arrow in fig. 2).

It should be noted that the driving device 60 can be connected to only the first vertical plate 10, only the second vertical plate 20, or both the first vertical plate 10 and the second vertical plate 20. The above-described connections may be direct connections or indirect connections through other structures.

Specifically, the included angle between the bearing surface of the feeding bed section 40 and the horizontal plane may be 10 °, 15 °, 20 °, 25 °, or 30 °. Preferably, the angle between the bearing surface of the feeding bed section 40 and the horizontal plane is 20 °.

For ease of description, spatially relative terms such as "above … …", "above … …", "above … … upper surface", "above", etc. may be used herein to describe the spatial positional relationship of one device or feature to other devices or features as shown in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" may include both orientations of "above … …" and "below … …". The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

It should be noted that the terms "first", "second", and the like are used to define the components, and are only used for convenience of distinguishing the corresponding components, and the terms have no special meanings unless otherwise stated, and therefore, the scope of the present invention should not be construed as being limited.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art.
