Technical Field

[0001] This utility model relates to a cooling and air supply device for loading and unloading cargo in a vehicle, belonging to the field of cigarette logistics technology. Background Technology

[0002] In cigarette logistics centers, loading and unloading goods is a frequent and labor-intensive task. Currently, the common method involves installing telescopic chain conveyors at the cigarette warehouse gate. These conveyors are gradually extended into the cargo box, and workers then move goods (such as cigarettes) from the cargo box to the conveyor, or vice versa. However, the cargo boxes of vehicles are typically 9 to 15 meters long, with narrow, poorly ventilated interiors. Especially in summer or high-temperature environments, the temperature inside the cargo box rises rapidly, and poor air circulation makes it easy for workers to suffer from heatstroke, fatigue, and other health problems during prolonged work. This not only affects work efficiency but also poses certain occupational safety risks. Utility Model Content

[0003] Based on the above, this utility model provides a cooling and ventilation device for loading and unloading cargo in a vehicle, which provides workers with localized cooling and ventilation during the loading and unloading process, so as to improve the working environment and protect the health of workers.
