In the description of the present invention, "several" and "several" mean two or two more than one, unless otherwise explicitly and specifically limited.

A drive chain and a sorting trolley connection structure of a narrow-band sorter. The chain 3 includes a chain plate 31, a pin shaft 33 and a guide running wheel 32. A slot is formed between the wheels 32 , the bottom end of the guide running wheel 32 is lower than the chain plate 31 , the chain plate 31 includes an inner plate 312 and an outer plate 311 , and the inner plate 312 is higher than the top of the guide running wheel 32 , the sorting trolley 2 is fixed with the inner panel 312 .

As shown in Figure 1, when in use, the drive chain 3 is mounted on the frame 11 of the sorter, and has a main drive chain 12 on the frame 11, and the teeth of the main drive chain 12 can extend into the slot , when the main drive chain 12 rotates, it drives the chain 3 to move, thereby making the sorting trolley 2 above it move.

There are two chains 3, and the two are arranged in parallel and symmetrically. There are several chain links on the chain 3. Every two guide running wheels 32 and chain plates 31 constitute a chain link, and the connection of two adjacent chain links shares a guide running wheel. 32. The guide running wheel 32 and the chain plate 31 are connected by the pin shaft 33. The two chains 3 are distributed along the Y direction in Figure 1.
