DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] An embodiment of the present utility model provides a controlled atmosphere refrigerated fresh-keeping vehicle.

[0025] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, including a vehicle body 1, which is the main body of a fresh-keeping vehicle. A carriage 2 is arranged on the vehicle body 1, and the carriage 2 is used for enclosing and loading goods. Two carriage doors 3 are rotatably connected to the tail of the carriage 2, and the carriage doors 3 are used to close and seal the carriage 2. A refrigerator 4 is arranged at the head of the carriage 2. The refrigerator 4 is a machine that transfers the heat of a cooled object with a lower temperature to the environmental medium to obtain cold energy. The heat transferred from the lower temperature object is customarily called cold energy. The working medium participating in the thermodynamic process change (energy conversion and heat transfer) in the refrigerator 4 is called a refrigerant. The refrigeration temperature range is usually above 120K, and below 120K belongs to the range of cryogenic technology. The refrigerator 4 is widely used in industrial and agricultural production and daily life. An air-conditioning equipment 5 is arranged at the upper end of the carriage 2. The air-conditioning equipment 5 artificially controls the proportion of components such as nitrogen, oxygen, carbon dioxide, and ethylene, humidity, temperature (above the freezing critical point), and air pressure in the gas in the air-conditioned fresh-keeping warehouse. By inhibiting the respiration amount of the cells of the stored object, its metabolism process is delayed, and it is in a nearly dormant state rather than a state of cell death. Thus, the texture, color, taste, nutrition, etc. of the stored object can be maintained basically unchanged for a long time, and then the effect of long-term freshness preservation can be achieved. Even after the fresh-keeping stored object leaves the air-conditioned fresh-keeping environment, its cell life activities will still maintain the normal metabolism rate in the natural environment and will not mature and deteriorate quickly, which has been fully disclosed and will not be elaborated too much here. The output end of the air-conditioning equipment 5 is connected to the inside of the carriage 2 through a connecting pipe 6; a chute 7 is opened at the bottom of the carriage 2, and a connecting structure is arranged on the inner wall of the chute 7. The connecting structure includes a driving motor 8, a bidirectional threaded rod 9 is fixed to the driving end of the driving motor 8, both outer surfaces of the bidirectional threaded rod 9 are threadedly connected with threaded sleeves 10, two hinge frames 11 are rotatably connected to the upper ends of the two threaded sleeves 10, two sliders 12 are rotatably connected to the upper ends of the two hinge frames 11, an adjusting plate 13 is slidably connected to the outer surfaces of the two sliders 12, a stabilizing rod 14 is fixed to the middle of the adjusting plate 13, a stabilizing block 15 is fixed to one end of the adjusting plate 13, and a limiting rod 16 is slidably connected to the middle of the stabilizing block 15.

[0026] Please refer to again Figure 1 , Figure 2 , Figure 3 and Figure 4 , it is worth specifically explaining that both ends of the limiting rod 16 are fixed to the inner wall of one side of the carriage 2, the outer surface of the stabilizing block 15 is slidably connected to the inner wall of one side of the carriage 2, the middle of the stabilizing block 15 is slidably connected to the outer surface of the limiting rod 16, one end of the stabilizing block 15 is fixed to the middle of one end of the adjusting plate 13, the outer surface of the adjusting plate 13 is slidably connected to the inner wall of the carriage 2, the outer surfaces of the two sliders 12 are slidably connected to the inner walls of both sides of the bottom of the adjusting plate 13, the middle of the two sliders 12 is slidably connected to the inner walls of both sides of the stabilizing rod 14, the middle of the two threaded sleeves 10 is threadedly connected to both outer surfaces of the bidirectional threaded rod 9, the outer surfaces of the two threaded sleeves 10 are slidably connected to the inner walls of both sides of the chute 7, the driving motor 8 is arranged on the inner wall of one end of the chute 7, and the outer surface of the bidirectional threaded rod 9 is rotatably connected to the inner wall of the chute 7.

[0027] Please refer to again Figure 1 、 Figure 2 、 Figure 3 and Figure 4 For specific description, a limiting groove 17 is formed at the upper end of the adjusting plate 13. A driving frame 18 is slidably connected to the inner wall of the limiting groove 17. Both ends of the driving frame 18 are rotatably connected to a connecting frame 19. The other ends of the two connecting frames 19 are rotatably connected to a rotating rod 20. The two rotating rods 20 are detachably installed at the upper end of the side of the carriage 2 close to the carriage door 3 through bolts. One end of the connecting frame 19 is rotatably connected to the outer surface of the two rotating rods 20, and the other ends of the two connecting frames 19 are rotatably connected to both ends of the driving frame 18. The outer surface of the driving frame 18 is slidably connected to the inner wall of the limiting groove 17. The vertical section of the driving frame 18 is T-shaped, and the cross section of the limiting groove 17 is T-shaped. The rotating rod 20 is detachably arranged, and connecting frames 19 with different lengths can be replaced according to needs to ensure that the driving frame 18 is normally applicable to the material pushing operation.

[0028] When the utility model is in use: First, the driving motor 8 drives the bidirectional threaded rod 9 to rotate, so that the two threaded sleeves 10 threadedly connected to the outer surfaces on both sides of the bidirectional threaded rod 9 slide in the reverse direction under the limitation of the sliding groove 7. The two reversely sliding threaded sleeves 10 drive the hinge frame 11 to fold. The folded hinge frame 11 drives the adjusting plate 13 to move vertically under the limitation of the stabilizing rod 14, the stabilizing block 15 and the limiting rod 16 through the two sliders 12. The vertically moving adjusting plate 13 can adjust the space inside the carriage 2, achieving the effect of space adjustment. The size of the space can be adjusted according to the actual amount of goods loaded to reduce the use of refrigeration capacity and controlled atmosphere amount, which is beneficial to saving resources, and then achieving the effect of improving the practicability of the controlled atmosphere refrigerated and fresh-keeping vehicle. Subsequently, the driving motor 8 drives the bidirectional threaded rod 9 to rotate, so that the rotating bidirectional threaded rod 9 drives the adjusting plate 13 to descend through the hinge frame 11. The descending adjusting plate 13 drives the driving frame 18 slidably connected thereto to slide under the limitation of the connecting frame 19 and the rotating rod 20. The sliding driving frame 18 pushes the goods stacked between the driving frame 18 and the carriage door 3, achieving the effect of auxiliary unloading. Most of the goods can be pushed to the carriage door 3, providing convenience for the unloading operation of the staff, and then achieving the effect of improving the use convenience of the controlled atmosphere refrigerated and fresh-keeping vehicle.

[0029] Working principle: The driving motor 8 drives the bidirectional threaded rod 9 to rotate, so that the threaded sleeve 10 connected to the bidirectional threaded rod 9 drives the adjusting plate 13 to move through the hinge frame 11, achieving the effect of spatial adjustment. The spatial size can be adjusted according to the actual amount of goods loaded, so as to reduce the use of refrigeration capacity and controlled atmosphere amount, which is beneficial to saving resources, and then improve the practicality of the controlled atmosphere refrigerated fresh-keeping vehicle. Subsequently, the driving motor 8 drives the bidirectional threaded rod 9 to rotate, so that the threaded sleeve 10 connected to the bidirectional threaded rod 9 is pulled by the adjusting plate 13, and the driving frame 18 is pulled to push the goods, achieving the effect of auxiliary unloading. Most of the goods can be pushed to the door 3 of the compartment, facilitating the unloading operation of the staff, and then improving the convenience of use of the controlled atmosphere refrigerated fresh-keeping vehicle.
