The invention provides a garbage collecting vehicle. The garbage collecting vehicle comprises a vehicle body; the vehicle body comprises a vehicle head; a hopper is arranged in front of the vehicle head; the hopper is connected with the vehicle body through a mechanical arm; the mechanical arm corresponds to the vehicle head and is n-shaped; one end, far away from the hopper, of the mechanical armis hinged on the vehicle body; a sealing box is arranged on the vehicle body; a sealing door is arranged at one end, far away from the vehicle head, of the sealing box; the sealing door is hinged with the position, near the above part, of the sealing box; and a locking mechanism is arranged on the sealing door and is used for controlling locking. According to the technical scheme of the embodiment of the invention, the sealing door is provided, so that the odor of the garbage is prevented from being diffused and secondary pollution is avoided; the locking mechanism is provided, so that untight sealing and garbage leakage caused by the fact that the sealing door is subjected to the internal pressure are avoided; and the garbage in a small garbage vehicle can be collected and put into the sealing box through the forward turning type mechanical arm and the hopper, so that secondary pollution caused by long-distance transportation of the small garbage vehicle is avoided and the workload of sanitation workers is reduced.
