Freight transporting device

Abstract

The invention provides a freight transporting device. The freight transporting device comprises a box body, a box door, a humidifying device, a control device and a plurality of humidity sensors. The box door is hinged to the box body. A separation plate is arranged in the box body. The inside of the box body is divided into a water chamber and a freight holding chamber through the separation plate. A plurality of sets of frame bodies used for holding vegetables and fruits are arranged on the inner wall of the freight holding chamber from top to bottom. The humidity sensors are arranged in all the frame bodies respectively. The box body is provided with an air inlet and an air outlet. The humidifying device comprises a driving device and a main rod which is arranged in the freight holding chamber. One end of the main rod penetrates through the separation plate to extend into the water chamber. The driving device is used for driving the main rod to rotate. A water passing channel is formed in the main rod. An inlet of the water passing channel is communicated with the water chamber. Branch pipes are arranged on the main rod. Branch pipe inlets are communicated with the water passing channel of the main rod. The ends, far away from the main rod, of branch rods are provided with mist sprinklers respectively. The control device is connected with the humidity sensors, first valves and the driving device. The freight transporting device is good in heat preservation and moisturizing effect, and is capable of preventing the vegetables and fruits from wilting and withering, exchanging gas inside and outside the box body, and being used repeatedly.

Description

technical field [0001] The invention relates to the technical field of cargo transportation equipment, in particular to a cargo transportation device. Background technique [0002] At present, the fresh-keeping boxes used for keeping vegetables and fruits mainly include plastic fresh-keeping boxes and foam boxes. Plastic fresh-keeping boxes include fully-sealed incubators and ordinary plastic transfer boxes; foam boxes include fully-sealed and breathable types. Fully-sealed plastic storage boxes cannot exchange gas inside and outside the storage box, which is not conducive to the preservation of fresh agricultural products; ordinary plastic transfer boxes are not conducive to heat preservation and moisture retention in the box, and are also not conducive to the preservation of fresh agricultural products. The fully-closed foam box is the same as the plastic fresh-keeping box of the fully-closed box, which is not conducive to the gas exchange inside and outside the box. At t...

AI Technical Summary

Problems solved by technology

Fully-sealed plastic storage boxes cannot exchange gas inside and outside the storage box, which is not conducive to the preservation of fresh agricultural products; ordinary plastic transfer boxes are not conducive to heat preservation and moisture retention in the box, and are also not conducive to the preservation of fresh agricultural products

The fully-closed foam box is the same as the fully-closed plastic fresh-keeping box, which is not conducive to the gas exchange inside and outside the box. However, the heat preservation effect is not good, and the leaves of vegetables and fruits will easily wilt due to insufficient water, and it is also a one-time use product
