The invention discloses an automatic arrangement device for a hose laying vehicle. The automatic arrangement device comprises a hose box used for containing hoses and a hose guide frame arranged at the edge of the top of the hose box. The automatic arrangement device further comprises a hose winding device, a transverse moving mechanism and a longitudinal moving mechanism which are arranged above the hose box. The transverse moving mechanism drives the hose winding device to move transversely along the top of the hose box, the hose winding device drives the hoses to be laid transversely, the longitudinal moving mechanism drives the hose winding device to move longitudinally, the hose winding device drives the hoses to be laid longitudinally, and then automatic arrangement of the hoses is completed. The automatic arrangement device is simple in structure and reliable in operation, achieves full mechanization and automation of hose retrieval operation, lowers labor intensity of workers and increases hose retrieval speed.
