Further, a plurality of first compressors 111 installed on the bottom transport layer 10 are arranged in the unloading area 11, each first conveyor belt 30 includes at least one feeding end, and each feeding end is correspondingly connected with one first compressor 111.

After the truck for transporting goods (including heavy and light parts) stops at the part unloading area 11, the first telescopic machine 111 can be extended and extended into the cargo box of the truck, and the first telescopic machine 111 can convey the light parts in the cargo box onto the first conveying belt 30, so that the part unloading efficiency is improved.

In this embodiment, each first conveyor belt 30 includes two feeding ends, that is, each feeding end is correspondingly connected to one first telescopic machine 111, and the two first telescopic machines 111 connected to each first conveyor belt 30 correspond to one parking space, so as to further improve the unloading efficiency.

When the first telescopic machine 111 unloads the light parts, the heavy parts can be unloaded and transported simultaneously through a conveying device (such as a forklift), and the conveying device can run between the two first conveying belts 30 when unloading the heavy parts. Of course, in order to ensure that the conveying device can normally run between two first conveying belts 30, a certain distance needs to be kept between two adjacent first conveying belts 30. As an example, the distance between every two adjacent first conveyor belts 30 is 4.2m, and the distance between two first compressors 111 in each first conveyor belt 30 is 3 m.

Further, as shown in fig. 5, a plurality of second compressors 124 installed on the bottom transportation layer 10 are provided in each piece loading area 12, each second conveyor belt 40 is provided with a plurality of piece discharging channels 41 leading to the piece loading area 12 corresponding thereto, and a piece discharging end of each piece discharging channel 41 is provided with one second compressor 124 corresponding thereto.

In the structure, the second telescopic machine 124 is correspondingly arranged at the delivery end of each delivery passage 41, when loading is carried out, the second telescopic machine 124 extends and extends into a container of the truck, light parts on the second conveying belt 40 move to the second telescopic machine 124 through the delivery passage 41, and the second telescopic machine 124 finally conveys the light parts to the container of the truck, so that the loading efficiency is improved.

It should be noted that, the first compressor 111 and the second compressor 124 can refer to the specific structure of the related stream compressors, and are not described herein again.

Further, in this embodiment, the bottom transportation layer 10 further has a manual loading area 125, and the express sorting system 100 further includes a seventh conveyor belt 80, the seventh conveyor belt 80 extends from the manual loading area 125 to above the primary sorting portion 21, a projection of a portion of the seventh conveyor belt 80 above the primary sorting portion 21 and a projection of a portion of each second conveyor belt 40 above the secondary sorting portion are arranged in a crossing manner, and each second conveyor belt 40 is used for receiving the light pieces on the seventh conveyor belt 80.

The light parts which are not unloaded from the truck are conveyed by the seventh conveyor belt 80 in the manual loading area 125, and are conveyed to each of the packing area 12, the floor sorting area 16 or the small part sorting area 241 after being primarily sorted.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
