Description

Technical Field

[0001] The utility model relates to the technical field of cold chain transportation, and in particular to a loading auxiliary device used for cold chain transportation of agricultural and sideline products. Background Art

[0002] Agricultural and sideline products are by-products brought about by agricultural production, including products from the five industries of agriculture, forestry, animal husbandry, sideline products, and fishery. They are divided into several major categories, including grain, cash crops, bamboo and wood, industrial oil and lacquer glue, poultry and livestock products, silkworm cocoons and silk, dried and fresh fruits, dried and fresh vegetables and condiments, medicinal materials, local by-products, aquatic products, etc. Each major category is divided into several minor categories. In the process of cold chain transportation of agricultural and sideline products, they need to be loaded onto cold chain transport vehicles.

[0003] The existing patent publication number is CN216710657U, which is a loading auxiliary equipment for cold chain transportation of agricultural and sideline products. It belongs to the field of cold chain transportation technology and includes a mobile base. A belt conveyor is arranged above the mobile base. Baffles are equidistantly installed on the conveyor belt of the belt conveyor. The belt conveyor is arranged at an angle. Side panels are fixedly installed on the front and rear sides of the belt conveyor. The surface of the side panels is connected to the mobile base through a supporting assembly. The utility model can transport products to the height of the carriage through the inclined belt conveyor and drop them on the receiving plate. The user can take the products out of the receiving plate and stack them inside the carriage. The setting of this structure can effectively solve the problem of time-consuming and labor-intensive manual handling. The belt conveyor in this device is also provided with a height adjustment assembly, and the use angle of the belt conveyor can be adjusted according to the height of the cold chain carriage to meet the loading needs of cold chain transport vehicles of different models.

[0004] When loading goods, the refrigeration device in the car is generally turned off to prevent cold air from blowing out quickly from the upper part of the car. The lower part will quickly suck in the hot air from the outside, causing the temperature in the car to rise rapidly. However, in the above technical solution, when transporting the goods, workers are required to transfer and stack them at both ends of the device, which increases the workload of the workers and makes the loading efficiency low. Too long loading time will cause the ambient temperature in the car to be too high, which will affect the temperature of the transported goods and thus affect the quality of the goods.

[0005] Therefore, a loading auxiliary equipment for cold chain transportation of agricultural and sideline products is proposed. Utility Model Content
