[0064] Embodiment two:

[0065] On the basis of embodiment 1, in order to make the cold air uniformly blow to the goods in the compartment, therefore, an adjusting structure for adjusting the conveying direction of the cold air is arranged on the conveying structure.

[0066] Wherein, the adjusting structure includes a plurality of guide plates 4 rotationally mounted in the interior of the exhaust cover 202 for guiding the outflow direction of the cold air, a linkage rod 401 rotationally mounted on one side of the guide plate 4, a linkage assembly arranged on the linkage rod 401 for driving the linkage rod 401 to move up and down, the linkage rod 401 moves at the same time to drive the guide plate 4 to overturn and swing up and down, so as to change the conveying direction of the cold air.

[0067] Specifically, the linkage assembly includes a linkage shaft 402 arranged on one side of the linkage rod 401 and a guide strip 403 arranged below the U-shaped frame 3 for guiding the moving direction of the linkage shaft 402, the inside of the guide strip 403 is provided with a wave-shaped guide groove 404, and the linkage shaft 402 is movably installed in the wave-shaped guide groove 404. The exhaust hood 202 moves while being able to drive the linkage rod 401 to move through the guide plate 4, and the linkage rod 401 can drive the linkage shaft 402 to move in the wave-shaped guide groove 404. When the linkage shaft 402 moves, it will be affected by the wave-shaped guide groove 404 and perform lifting movement.

[0068] Working principle:

[0069] In use, the support guard 205 is fixed on the top of the carriage by bolts or welding, and the refrigeration machine 103 is started to make the cold air conducted to the exhaust top frame 1 through the through pipe 102, the cooling exhaust pipe 101, the exhaust top frame 1, the adapter straight pipe 203, the corrugated pipe 201 and the connecting straight pipe 2, and then into the guide groove 208 in the U-shaped guide frame 207, and then discharged into the carriage through the guide groove 208 and the exhaust hood 202. In the process, the motor 304 can be started, which can be installed outside the carriage, and the output end penetrates the carriage and the support guard 205. When the motor 304 is started, the output end can drive the linkage bevel gear 303 to rotate, so that the linkage bevel gear 303 drives the threaded rod 301 to rotate in the inside of the U-shaped frame 3 through the thread cooperation with the driven bevel gear 302. The continuously rotating threaded rod 301 can drive the U-shaped guide frame 207 to slide horizontally, so that the U-shaped guide frame 207 drives the exhaust hood 202 and the connected adapter straight pipe 203 to move. When the adapter straight pipe 203 moves, it can drive the corresponding sliding seat 204 to slide on the guide rod 206. At the same time, the moving adapter straight pipe 203 can drive the connecting straight pipe 2 to move and change the angle through the adapter straight pipe 203. In the process, the corrugated pipe 201 will bend to adapt to the movement of the U-shaped guide frame 207, so that the movement of the U-shaped guide frame 207 will not affect the normal delivery of the cold air. Therefore, by controlling the output end of the motor 304 to rotate forward and backward, the exhaust hood 202 can move reciprocatingly in the carriage, so that the cold air is uniformly distributed in the carriage. At the same time, the exhaust hood 202 can drive the linkage rod 401 to move through the guide plate 4, and the linkage rod 401 can drive the linkage shaft 402 to move in the wave-shaped guide groove 404. When the linkage shaft 402 moves, it will be affected by the wave-shaped guide groove 404 and perform lifting movement, so that the linkage shaft 402 drives the linkage rod 401 to lift, and the linkage rod 401 lifts while driving the guide plate 4 to overturn and swing up and down, changing the delivery direction of the cold air, so that the cold air blows uniformly to the refrigerated goods. The wave-shaped guide groove 404 is set to be deeper than the length of the linkage shaft 402, so that the linkage shaft 402 can avoid being blocked by the inner wall of the wave-shaped guide groove 404 when lifting.

[0070] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application also intends to include these modifications and variations.
