As shown in fig. 4, the sorting wheels 2 are arranged in even number rows, and two rows are in a group and are frictionally driven by a driving device 5, in detail, the driving device 5 includes driving rollers 51 located between two rows of sorting wheels 2 and attached to the two rows of sorting wheels 2, and the driving rollers 51 are in contact with the upper semicircle of the sorting wheels 2, the driving rollers 51 are rotatably mounted on a support 52 on a frame and are driven to rotate by a first power source, the driving rollers 51 may be made of various known materials, such as metal shafts coated with wear-resistant plastics, the first power source (not shown) may be various known devices or structures capable of driving the rotating shafts to rotate, such as a mechanism formed by a single motor or a motor and gear transmission structure, a mechanism formed by a motor and belt transmission structure, or a mechanism formed by a motor and sprocket transmission structure, etc., are known in the art and will not be described in detail.

Furthermore, each driving device 5 may have an independent first power source, and preferably, a plurality of driving devices 5 share one first power source, which is implemented as follows:

as shown in fig. 4, one end of one driving roller 51 of the plurality of driving devices 5 is connected to a power source, and taking as an example that the outermost driving roller 511 is connected to a first power source, the other end of the driving roller 511 is connected to the same end of a driving roller 512 adjacent to the driving roller 511 through a pulley 52 and a belt 53 or a sprocket and a chain; the other end of the driving roller 512 is connected to the same phase end of another driving roller adjacent thereto through a pulley and a belt or a sprocket and a chain, and so on, thereby driving the plurality of driving rollers 51 by one power source.

Moreover, since the position of the driving roller 51 is fixed, but as the driving roller 51 and the sorting wheel 2 wear for a long time, the contact between the two is gradually reduced, and even a gap is formed, so that the driving roller 51 cannot drive the sorting wheel 2 to rotate by friction force, and thus the conveying of the articles cannot be performed, and therefore, each sorting wheel 2 is always kept attached to the driving roller 51 by the upward elastic force.

Specifically, as shown in fig. 6, the support 3 includes a support 31, the support 31 includes a connecting shaft 312 and an eccentric support plate 313 located above the connecting shaft 312, a positioning slot 311 is formed on the eccentric support plate 313, a support 32 is clamped in the positioning slot 311 in a manner of moving up and down relative to the positioning slot 311, the support 32 includes two first vertical plates 321 symmetrically clamped on the eccentric support plate 31 and located outside the positioning slot 311, the two first vertical plates 321 are respectively connected to a position-limiting body 322 embedded in the positioning slot 311, a support shaft 323 is erected on the two first vertical plates 321, two ends of the support shaft 323 are fixed to an approximately H-shaped installation body 324, an upper surface of a middle plate 3241 of the installation body 324 is an arc surface having the same curvature as that of the sorting wheel 2, a fixing shaft 325 is erected on two side plates 42 of the installation body 324, the sorting wheel 2 is rotatably arranged on the fixed shaft 325; a torsion spring 33 is disposed between the supporting body 32 and the support 31, the torsion spring 33 is sleeved on the outer periphery of the supporting shaft 323, one free end of the torsion spring 33 abuts against the eccentric supporting plate 313, the other free end of the torsion spring abuts against the intermediate plate 3241, and in a normal state, the torsion spring is compressed and deformed by the pressure of the driving roller 511 on the sorting wheel 2.

Therefore, when the sorting wheel 2 is not closely attached to the driving roller 51, the deformation restoring force of the torsion spring 33 causes the supporting body 32 to move upwards in a micro-scale relative to the support 31, so that the sorting wheel 2 moves upwards to closely attach to the driving roller 51 to realize effective friction driving.

Of course, in other embodiments, the driving roller 51 may contact with the lower half of the sorting wheel, and the driving roller 51 is elastically urged upward to always abut against the sorting wheel 2.
