[0041] like Figure 3 As shown, the transport container further includes an upper connecting beam 60, the two ends of which are respectively hinged to the two side walls 30 and are located above the front door 40. The upper cover 50 has an upper fixing groove, such as Figure 2 As shown, the transport container is unfolded to the use state, and the upper connecting beam 60 extends into the upper fixing groove, so that there will be no relative displacement between the upper cover 50, the two side walls 30 and the front door 40, thereby improving the stability of the transport container when in use.

[0042] like Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the transport container further includes a bottom plate 70, a first end of which is pivotally connected to an end of the supporting rear wall 20 close to the chassis 10, such as Figure 2 As shown, when the transport container is in use, the second end of the bottom plate 70 is located below the front door 40, as shown in FIG. Figure 6 and Figure 7 As shown, after the side wall 30 is folded, the bottom plate 70 is folded upward and located outside the sub-side wall 31 .

[0043] Optionally, the transport container further includes a hook disposed on the bottom plate 70, which is connected to the front door 40, thereby preventing the bottom plate 70 from tipping over under the action of gravity and ensuring that the bottom plate 70 can be stably maintained in the folded position.

[0044] like Figure 3 and Figure 6 As shown, the transport container further includes a lower connecting beam 80, the two ends of which are respectively hinged to the two side walls 30 and are located below the front door 40. The bottom plate 70 has a lower fixing groove, such as Figure 2As shown, the transport container is unfolded to the use state, and the lower connecting beam 80 extends into the lower fixing groove, so that there will be no relative displacement between the bottom plate 70, the two side walls 30 and the front door 40, thereby improving the stability of the transport container when in use.

In this way, the sub-side wall 31 is located in the receiving space after being folded, and will not interfere with the sub-side wall 31 during the folding process of the upper cover 50 and the bottom plate 70, thereby ensuring the stability of the collection and transport device in the folded state and improving the convenience of folding the collection and transport device.

[0047] like Figure 3 As shown, the supporting rear wall 20 further includes a limiting structure 24, which is connected to the first connecting portion 22, the second connecting portion 23 and / or the supporting portion 21, and the two side walls 30 are located between the two limiting structures 24. In this way, the rotation direction of the sub-side wall 31 is limited, and when the transport collection device is folded, the front door 40 is pushed toward the supporting rear wall 20, and the sub-side walls 31 on both sides are pushed inward, and the front door 40 approaches the supporting rear wall 20. On the contrary, the front door 40 is pulled, and the front door 40 drives the sub-side wall 31 to rotate relative to the front door 40, and the transport collection device is restored from the folded state to the use state.

[0048] Optionally, the limiting structure 24 for limiting the rotation direction of the side wall 30 includes a limiting rod 241 , a first end of the limiting rod 241 is connected to the first connecting portion 22 , and a second end of the limiting rod 241 is connected to the second connecting portion 23 .

[0049] Optionally, the limiting structure 24 further includes a reinforcing rod 242 , and the reinforcing rod 242 is connected between the limiting rod 241 and the supporting portion 21 .

[0050] like Figures 11 to 13As shown, the transport container further includes a side wall locking member 90, which is movably disposed on the side wall 30. A locking hole 71 is provided on the bottom plate 70. The side wall locking member 90 has a locking position and an unlocking position in a direction away from the bottom plate 70. Fig.12 As shown, the side wall locking member 90 is located in the locking position, and the side wall locking member 90 is inserted into the locking hole 71, so that the side wall 30 is fixedly connected to the bottom plate 70; Fig.13 As shown, the side wall locking member 90 is in the unlocked position, and the side wall locking member 90 is withdrawn from the locking hole 71, so that the side wall 30 can move relative to the bottom plate 70. In this way, when the side wall locking member 90 is in the locked position, the rear wall 20, the side wall 30 and the front door 40 are supported to form a stable rectangular parallelepiped structure, ensuring the rigidity and strength of the collection and transportation device when in use. When the side wall locking member 90 is in the unlocked position, the collection and transportation device can be easily and quickly folded to a folded state.

[0051] like Figures 11 to 13 As shown, the transport container also includes a mounting tube 150, which is fixedly connected to the side wall 30.

[0060] Optionally, the fixing member 130 is arranged in a V shape.

[0061] Optionally, the supporting rear wall 20, the side walls 30 and the front door 40 are firstly formed by overlapping a frame with steel pipes, and then a steel mesh is welded to the frame. The side wall 30 and the supporting rear wall 20 are pivotally connected by a hinge; the front door 40 and the side wall 30 are pivotally connected by a hinge; the upper cover 50 and the supporting rear wall 20 are pivotally connected by a hinge; the bottom plate 70 and the supporting rear wall 20 are pivotally connected by a hinge; and the two sub-side walls 31 are pivotally connected by a hinge.
