The reversing wheel is arranged in the wheel body accommodating part 51 and is coaxially and rotatably connected with the wheel body accommodating part 51. The chain body accommodating portion 52 includes an arc-shaped bent pipe section which is provided along the circumferential wall of the wheel body accommodating portion 51, and both are coaxially provided, intersecting and communicating. The reversing wheel comprises a wheel body, a chain piece groove 33 is formed in the outer circumferential surface of the wheel body along the circumference of the wheel body, the radial section of the chain piece groove 33 is arc-shaped, the arc diameter of the chain piece groove 33 is matched with the diameter of a chain piece 13 of the conveying chain 10 matched with the arc diameter of the chain piece groove, the chain piece can be vertically arranged in the chain piece groove along the direction of the wheel body diameter, the diameter of the cross section of the chain body accommodating part 52 is matched with the diameter of the chain piece, preferably, the diameter of the chain piece groove is equal to the diameter of the cross section of the chain body accommodating part 52, and when the reversing wheel is arranged in the wheel body accommodating part, a complete tubular channel chain piece and a tubular channel are formed between the inner wall of an arc-shaped bent pipe section of the chain body accommodating part 52 and the wall of the chain piece groove 33 in a friction sliding connection. When the conveyer chain 10 is used, the conveyer chain 10 winds on the reversing wheel and passes through the tubular passage, when the conveyer chain 10 moves, the chain piece 13 positioned outside the reversing device approaches the wheel body along the tangential direction of the wheel body until the chain piece 13 contacts with the wall of the chain piece groove 33, and the friction force between the chain piece 13 and the wall of the chain piece groove 33 drives the reversing wheel to rotate, so that when the conveyer chain 10 turns, the sliding friction force between the chain piece 13 and the reversing wheel of the conveyer pipe 40 can be converted into the driving force for driving the reversing wheel to rotate in the reverser shell 50, the resistance of the conveyer chain in the turning process is reduced, the unnecessary energy consumption is reduced, the abrasion of the chain piece 13 is reduced, the abrasion to the edge of the chain piece 13 is reduced, and the service life of the conveyer chain 10 is prolonged.

In addition, because the loop chain can be supported by the chain piece 13 and far away from the chain piece groove of the reversing wheel, the loop chain can not contact with the reversing wheel all the time, the loop chain and the reversing wheel can not mutually wear, and because the chain piece 13 contacts with the wheel body along the tangential direction, the collision between the chain piece 13 and the wheel body is softer, and therefore, the noise and the wear generated by the contact of the conveying chain 10 and the reversing wheel are relatively smaller.

The shaft hole is arranged at the geometric center of the second supporting plate. By adopting the structure, the supporting plate divides the outer wheel ring into two symmetrical sides, thereby ensuring the contact area of the chain wheel and the chain piece and reducing the whole quality.
Because there is a gap between the inner wall of the wheel body accommodating portion 51 of the commutator housing 50 and the end face of the outer wheel ring 31, so that material may enter the gap between the second support plate 32 and the inner wall of the wheel body accommodating portion 51 from the gap, in order to guide out the material in the gap, as shown in the drawing, it is preferable that a discharge chute 34, a guide edge 35 and a pillow block 37 are provided on the commutator wheel, the pillow block 37 is provided in the center of the support plate, the shaft hole is provided on the pillow block 37, both end faces of the pillow block 37 are respectively located on both end faces of the support plate, and the pillow block end faces are lower than the end face of the outer wheel ring or are flush with the end face of the outer wheel ring.

When the reversing wheel rotates, the guide edge 35 meets the material positioned between the second supporting plate 32 and the inner wall of the chain wheel accommodating part, the guide edge 35 pushes the material falling on the inner wall of the chain wheel accommodating part to move, under the guiding action of the arc-shaped structure of the guide edge 35, the material moves along the convex surface of the guide edge 35 towards the direction of the outer wheel ring 31 until the material moves to the discharge chute 34 and enters the chain plate groove 33 from the discharge chute 34, and the material entering the chain plate groove 33 can be taken away by the chain plate 13. By adopting the chain wheel with the structure, falling materials can be collected into the chain piece groove again and taken away by the chain piece, so that the loss of the materials during turning of the conveying chain can be prevented, and the chain wheel is prevented from being blocked by the materials.
