More specifically, the reciprocating mechanism 42 in this embodiment employs a hydraulic cylinder having a fixed end hinged to the top of the support frame 41 and an extension rod fixed to the movable section 22. In some embodiments, the hydraulic ram employed by the reciprocating mechanism 42 may be replaced with a pneumatic cylinder or an electric push rod.

In the present embodiment, preferably, the fixed segment 21 and the movable segment 22 are connected by three rotating mechanisms 3, and the rotating mechanisms 3 are distributed in parallel at intervals; more specifically, each of the rotating mechanisms 3 is a hinge, and two pairs of hinges are located at edge positions on both sides.

The frame 1 of the present embodiment includes two first legs 11 and two second legs 12, each of the first legs 11 and the second legs 12 is located below the head end and the tail end of the fixed section 21, and the height of each of the first legs 11 is greater than the height of the second legs 12. The arrangement is such that a certain inclination can be obtained after the fixed section 21 is lapped on the frame 1. When the belt conveyor retracting device is arranged on a movable sorting platform (namely a transport vehicle), the split belt device is obliquely arranged, so that after the movable section 22 is unfolded, the ground clearance of the tail end of the movable section is lower than that of the platform, and cargos can be conveniently placed on the movable section 22 by a forklift or in a manual mode and then are conveyed to the sorting platform. In some embodiments, it is further preferable that the first leg 11 and the second leg 12 are telescopic legs, each telescopic leg comprises an outer leg tube and an inner leg tube embedded in the outer leg tube, and the height of the outer leg tube of each first leg 11 is greater than the height of the outer leg tube of each second leg 12.
