Detailed Description

The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

Example (b): as shown in fig. 1 to 7, a stable wheat wheel device comprises a wheat wheel main body 11, a roller 12, a mounting hole 13, a screw groove 14, an inner polygonal pipe unit 1 inserted into the mounting hole 13 and connected to the screw groove 14, and a film coating unit 2 disposed on the inner polygonal pipe unit 1 and elastically clamped between the wheat wheel main body 11 and the inner polygonal pipe unit 1 and between the inner polygonal pipe unit 1 and a polygonal rod body a.

Among the prior art, the most important structure of sorting machine is exactly to turn to the part, and it gives the different ejection of compact direction of delivery of goods to reach the letter sorting effect. However, in the existing multi-directional sorting machine, the steering component comprises a rotating motor, a rotating base, a driving motor and a driving roller, so that the structure of the whole steering component is complex, and the use and maintenance cost is high.

Therefore, in this embodiment, the plurality of wheat wheel devices and the polygonal rod body a form the wheat wheel rod structure, and the two wheat wheel rods symmetrical to the roller 12 can realize a theoretically infinite sorting and discharging directions, and can completely meet the current sorting requirements.

Therefore, the wheat wheel device needs to have annular clamping and axial fixing effects on the polygonal rod body a, the former ensures that a large torque force can be output, and the latter prevents the wheat wheel device from shifting, otherwise, the friction conveying action on the lower surface of the goods is deflected, and the goods can rotate on the wheat wheel rod, which is very unfavorable.

Therefore, in this embodiment, the inner polygonal tube unit 1 enables the existing wheat wheel structure to have a square or regular hexagonal inner hole, so as to ensure circumferential clamping and fixing, and the film coating unit 2 is mainly used for clamping between the inner polygonal tube unit 1 and the polygonal rod body a, so that the whole wheat wheel device is not easy to loose axially on the polygonal rod body a.

The inner polygonal pipe body unit 1 includes a fixing plate 101 provided on a side plane of the head block 11, a polygonal opening 102 provided on the fixing plate 101 and located inside the mounting hole 13, and an inner polygonal pipe 103 provided on the fixing plate 101 and inserted into the mounting hole 13, the inner polygonal pipe 103 having an inner side surface shape aligned with the polygonal opening 102. The inner polygonal pipe body unit 1 further includes a screw hole 104 provided on the fixing plate 101, and a fixing bolt 105 provided on the screw hole 104 and the screw groove 14.

In this embodiment, the polygonal opening 102 and the inner hole of the inner polygonal tube 103 are identical in position, shape and size, so as to ensure that the polygonal rod body a can be smoothly inserted and circumferentially limited.

The polygonal opening 102 is square or regular hexagon in shape. The outer side surface of the inner polygonal pipe 103 is a circular ring surface, and the outer diameter of the inner polygonal pipe 103 is 2-5mm smaller than the aperture of the mounting hole 13.

In this embodiment, the outer diameter of the inner polygonal tube 103 needs to be relatively large, otherwise the wall thickness of the inner polygonal tube 103 may be insufficient, affecting the structural strength thereof.

The film covering unit 2 comprises a circular ring-shaped main body film 201 which is arranged on the side plane of the fixing plate 101 and exposes out of the polygonal opening 102, a circular ring-shaped transition film 202 which is arranged on the outer ring edge of the circular ring-shaped main body film 201, a circular ring-shaped clamping film 203 which is arranged on the outer ring edge of the circular ring-shaped transition film 202 and is positioned between the fixing plate 101 and the wheat wheel main body 11, and an anti-skid clamping strip 204 which is arranged on the inner ring edge of the circular ring-shaped main body film 201 and is positioned between the inner polygonal pipe 103 and the polygonal rod body a.

In this embodiment, the circular clamping film 203 replaces the conventional common gasket, and the anti-slip clamping strip 204 replaces the conventional common elastic sheet, so as to ensure that the whole film covering unit 2 has the advantages of high compactness and convenient and fast overall production.

Wherein, the whole film covering unit 2 is made of the existing high-strength rubber.

The film covering unit 2 further includes a protection hole 205 which is arranged on the circular ring-shaped main body film 201 and has a width smaller than the length of the hexagonal tail side of the fixing bolt 105.

In this embodiment, the protection hole 205 has two functions: first, in normal use, even if the fixing bolt 105 is loosened, the fixing bolt 105 is not easy to fall from the protective hole 205 with a relatively small size, so that the fixing bolt 105 is prevented from being lost; secondly, when the fixing bolt 105 needs to be tightened again, the protection hole 205 is properly opened, and the tightening operation is not affected, which is quite ingenious.

The thickness of the annular transition membrane 202 is smaller than that of the annular main body membrane 201 and smaller than that of the annular clamping membrane 203.

In this embodiment, the annular transition membrane 202 is only used to connect the annular main body membrane 201 and the annular clamping membrane 203, and thus it may also be replaced by several radial connecting strips.

The thickness of the annular clamping membrane 203 is greater than the annular main body membrane 201.

In this embodiment, the annular clamping film 203 is used to elastically clamp between the wheel body 11 and the fixing plate 101, so the thickness thereof needs to be relatively large to avoid being squashed too quickly, and the radial length of the annular clamping film 203 needs to be relatively large to ensure that the insertion of the fixing bolt 105 is not disturbed.

The number of the anti-skid clamping strips 204 is four or six.

In this embodiment, when the polygonal opening 102 is a square, the inner polygonal tube 103 is an "outer circle and inner square" tube, the cross-sectional shape of the polygonal rod a is a square, and the number of the anti-slip clamping strips 204 is four, and when the polygonal opening 102 is a regular hexagon, the inner polygonal tube 103 is an "outer circle and inner regular hexagon" tube, the cross-sectional shape of the polygonal rod a is a regular hexagon, and the number of the anti-slip clamping strips 204 is six, and the anti-slip clamping strips 204 are used for clamping and preventing slipping between opposite side surfaces.

And 6 or 8 wheat wheel devices are respectively and fixedly arranged on the last two polygonal rod bodies a, and then the polygonal rod bodies a are externally connected with a reversible motor, so that the objects can be sorted and conveyed in multiple discharging directions, and a steering structure in the conventional sorting machine is replaced.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various modifications can be made within the knowledge of those skilled in the art without departing from the gist of the present invention. These are non-inventive modifications, which are intended to be protected by patent laws within the scope of the claims appended hereto.
