Garbage conveying device and garbage treatment system

The utility model relates to a garbage conveying device and a garbage treatment system, and the garbage conveying device comprises a conveying pipe; the air inlet piece is communicated with one end of the conveying pipe in an openable and closable manner; the collecting assembly communicates with the other end of the conveying pipe, and the collecting assembly is used for exhausting air from the conveying pipe and collecting garbage; and the acceleration assembly is communicated with the conveying pipe in an openable and closable manner and is arranged between the air inlet piece and the collecting assembly. According to the garbage conveying device, when the conveying distance of the conveying pipe is long and the garbage density is large, the conveying speed of the garbage can be increased through the acceleration assembly, the conveying efficiency of the garbage can be improved, and the situation that the garbage with the large density sinks to the bottom and remains in the conveying pipe in the conveying
