Correspondingly, there is one first moving wheel 300 and it is provided on the side of the top beam 121 of the frame 120, and the axis of the second moving wheel 400 extends horizontally.

[0030] In another embodiment, as shown in the attached Figure 2 , Attachment Figure 3As shown, the base frame 110 includes a first crossbeam 111 and a second crossbeam 112 distributed in a T-shape. The extension direction of the first crossbeam 111 is parallel to the conveying direction of the conveying device 200. A pivot shaft 113 is provided in the middle of the first crossbeam, and a second joint bearing 114 is provided at the outer end of the second crossbeam. The articulation of adjacent sorting carts is achieved through the second joint bearing 114 and the pivot shaft 113.

[0031] As attached Figure 3 As shown, the second moving wheels 400 are installed at both ends of the first crossbeam 111, with the axis of the second moving wheel 400 extending horizontally. A square frame 120 is installed above the base frame 110, and the first moving wheel 300 is installed on the top of the square frame 120. The axial direction of the first moving wheel 300 extends in the vertical direction. At the same time, the first crossbeam is also provided with a limiting guide wheel 115 located between the two second moving wheels, and the axis of the limiting guide wheel extends in the vertical direction. Furthermore, to reduce the height of the sorting cart, the collector 600 of the busbar current collector is installed on the side of the second crossbeam 112.

[0032] Furthermore, the second moving wheel 400 is hinged to the end of the first beam 111 through the wheel seat 410. At the same time, the first moving wheel 300 is connected to the support shaft 310 at the top of the frame 120. The wheel seat 410 where the second moving wheel 400 is located and the connecting pin 420 of the first beam 111 are symmetrically distributed on both sides of the second beam 112. The support shaft 310 and the two connecting pins 420 are at the same distance in the conveying direction of the conveying device 200.

[0033] In order to facilitate the connection of the upper ends of different sorting carts, as shown in the attached Figure 4 As shown, two first moving wheels 300 are provided on the top of the top beam 121 of the frame 120 near both ends, and a first joint bearing 500 is installed on each of the support shafts 310 .

The locking bolt 320 passes through the through hole from the bottom of the top plate 122 and is screwed into the internal threaded hole of the support shaft 310 to achieve a fixed connection between the support shaft 310 and the top plate 122. At the same time, a gasket is also provided between the head of the locking bolt 320 and the top plate 122.
