It is a conventional technical means for those skilled in the art to drive the rollers 12 through the roller motor 14, the sprocket and the chain, so this part of the specific structure will not be described in detail here. In the utility model, the lower side of the roller frame 11 is fixedly connected with a support beam 13 at a position close to the front and rear sides thereof, and a lifting mechanism is provided between the support beam 13 and the rotating plate 20, and the roller frame 11 can be driven by the lifting mechanism. Lifting up and down, in addition, a rotating drive mechanism for driving the rotating plate 20 to rotate is provided on the base frame 30, and the rotating plate 20 is driven by the rotating drive mechanism to rotate the angle so that the roller frame 11 can follow the rotation. In order to position the transmitted items, the utility model also has positioning components on the left and right sides of the roller 12, and the roller frame 11 is provided with a positioning adjustment mechanism for driving the two positioning components to adjust the distance.

The rotation angle range is generally within 90 degrees clockwise and counterclockwise. This rotation angle is sufficient to meet most transportation needs, and if the utility model rotates 90 degrees clockwise, it will rotate 90 degrees counterclockwise to return to the initial position, and repeat this rotation work.

[0028] Specifically, the base frame 30 includes a fixed plate 31 located on the upper side, and a connecting sleeve 41 is rotatably arranged in the middle of the fixed plate 31, and the upper end of the connecting sleeve 41 is fixedly connected to the rotating plate 20, wherein the rotation driving mechanism includes a passive gear 42, a driving gear 43, a toothed belt 44 and a reduction motor 45, wherein the passive gear 42 is fixed to the lower end of the connecting sleeve 41, the driving gear 43 is fixed to the output shaft of the reduction motor 45, the toothed belt 44 is meshingly arranged on the driving gear 43 and the passive gear 42, and the reduction motor 45 is fixed to the fixed plate 31, and the driving gear 43 is driven to rotate by the reduction motor 45, and then the passive gear 42 is driven by the toothed belt 44, so the connecting sleeve 41 drives the rotating plate 20 to rotate, and since the roller frame 11 is connected to the rotating plate 20 through the lifting mechanism, the roller frame 11 also rotates accordingly.
