[0002] With the rapid development of my country's infrastructure, road grades are becoming increasingly higher. The roadbed is the foundation of the road surface, bearing vehicle loads together with the road surface. The particle size of the filler in the roadbed directly affects the quality of the roadbed compaction and is directly related to the subsequent settlement and cracking of the road surface. During the construction of the roadbed, the excavated earth and stone are directly transported to the filling area for filling. Generally, large-sized stones are screened out through on-site observation, and the large-sized stones are simply crushed before being directly filled.

[0003] In the prior art, a Chinese utility model patent document with authorization announcement number CN215142176U discloses a roadbed filler screening device, which is placed on a carriage when in use. During the loading process, small-particle ash filler leaks into the interior of the carriage, while large-particle roadbed filler slides to the outside through the oblique side of the tripod. After screening is completed, the roadbed filler screening device is disassembled and directly transported by a loading truck; the roadbed filler screening device is placed on the top of the carriage through a base frame, and has poor stability. During the loading process, the roadbed filler screening device is easily offset, affecting the screening process and thus affecting the loading efficiency.

[0004] Therefore, it is necessary to design a screening device for ash soil roadbed construction that can improve the connection stability between the carriage, is not prone to deviation during loading, and ensures loading efficiency to solve the current technical problems.
