Technical Field

[0001] The present invention relates to the field of cold chain transportation, and in particular to a cold chain transportation truck unloading device. Background Art

[0002] Agricultural products refer to primary products derived from planting, forestry, animal husbandry and fishery, that is, plants, animals, microorganisms and their products obtained in agricultural activities, such as rice, sorghum, peanuts, corn, wheat, fish and local specialties of various regions. Some agricultural products, such as fresh produce, fish, dairy products, etc., need to be transported through cold chain. The current cold chain transportation is carried out by intelligent cold chain trucks. Cold chain transportation refers to the transportation process in which the transported goods are always kept at a certain temperature, regardless of loading and unloading, changing the mode of transportation, replacing packaging equipment, etc. At present, the most common cold chain transportation is road transportation, and the vehicles are cold chain trucks.

[0026] Working principle: When the present invention is used, the transport vehicle body 1 is pushed to the rear door position of the cold chain truck through the moving wheel 2 and the push frame 3 at the bottom, and then the first motor 6 is controlled to operate to drive the transmission pulley 5 at the output end to rotate. The transmission pulley 5 drives the upper transmission pulley 5 and multiple support rollers 7 to rotate through the belt 8, so that the belt 8 moves up through the unloading structure 9 during transmission and moves up to the height of the bottom of the truck compartment. Then the second motor 904 is controlled to operate, and then drives the screw rod 903 at the output end to rotate in the movable box 902. When the screw rod 903 rotates, the threaded sleeve 905 is pushed to the front end through the thread, and then the threaded sleeve 905 drives the storage plate 906 to move forward. One side of the storage plate 906 is horizontally supported by the sliding seat and the slide rod 907, so The storage plate 906 is moved horizontally to the interior of the carriage, and the cold chain goods can be placed on the storage plate 906 for unloading. Then the second motor 904 is operated, and the storage plate 906 is driven to be retracted and moved to the rear end through the screw rod 903 and the threaded sleeve 905. Then the first motor 6 is controlled to operate, and the movable box 902 and the storage plate 906 are driven to move downward through the transmission pulley 5 and the belt 8, so that the storage plate 906 is stored in the unloading chute 11 after moving downward, and is located at the end of the unloading chute 11. At this time, the worker can push a stack of goods to the rear end and push it onto the roller 908, so that the goods are stored in the transport vehicle body 1. Then the storage plate 906 can be unloaded for the second time and the goods can be stored, so that the entire transport vehicle body 1 can unload and transport two stacks of goods, thereby improving transportation. In order to improve the transportation efficiency, when large-volume goods need to be unloaded, the two sets of bottom plates 1005 are respectively inserted into the first slot 1001 and the second slot 1003 through the positioning slot 1002, thereby increasing the two sides and the front end area of ​​the storage plate 906, and the two back plates 1006 are inserted into the locking slot 1004 and locked and fixed. Then, the large-volume goods in the cold chain truck can be placed on the storage plate 906. Under the restriction of the bottom plate 1005 and the back plate 1006, the goods are temporarily placed. Then, the elastic band 1007 at the top of the back plate 1006 is passed through the top of the goods and pulled down to close to the front end of the transport body 1, so that the buckle 1008 at the end of the elastic band 1007 is locked and fixed with the base 1009 at the front end of the transport body 1. Under the support and strapping restrictions, it is fixed for easy transportation. After the two piles of goods are unloaded, the second movable cover 1203 is driven to move to the front end by the push-pull block 1208, and the second movable cover 1203 drives the first movable cover 1202 to be pulled out from the outside of the refrigeration cover 1201 through the slider and the slide groove, and unfolded. When unfolding, the first movable cover 1202 and the second movable cover 1203 move in the movable groove 1206 through the pulley at the bottom, gradually wrapping the transport vehicle body 1, and then open the adhesive patch 1205, and unfold the thermal insulation curtain 1204. After the thermal insulation curtain 1204 is lowered, a sealing surface is formed vertically through the counterweight block at the bottom, and the transport vehicle body 1 and the goods are wrapped together with the first movable cover 1202, the second movable cover 1203 and the refrigeration cover 1201.At this time, the refrigeration structure 1207 is running and transmits cold air to the first movable cover 1202, the second movable cover 1203 and the interior of the refrigeration cover 1201, thereby providing a low-temperature environment for the goods and facilitating long-term cargo transportation.
