Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0027] Example 1

[0028] Reference Figure 1-2 , which is the first embodiment of the present utility model, provides a refrigeration device for agricultural product processing, including an external mechanism 100, the external mechanism 100 includes a refrigeration tank 105, and the refrigeration tank 105 is equipped with a gas transmission mechanism 200 and a circulation mechanism 300;

[0029] In addition, the gas transmission mechanism 200 includes a through pipe 202 connected to the bottom of the refrigeration tank 105, the surface of the through pipe 202 is snap-connected to the support frame 203, the bottom of the support frame 203 is fixedly connected to the shell 101, the outer side of the shell 101 is fixedly connected to the side plate 301, the two side plates 301 are fixedly connected to the opposite side of the threaded rod 302, the surface of the threaded rod 302 is threadedly connected to the slider 303, and the end face of the threaded rod 302 is fixedly sleeved with a crank handle 304, the side of the slider 303 is fixedly connected to the tensioning rod 305, the outer side sliding sleeve of the tensioning rod 305 is provided with an elastic belt 306, the elastic belt 306 is cooperated with an impeller 312, and the end face of the impeller 312 is fixedly penetrated by the shell 101.

[0030] Specifically, the external mechanism 100 is arranged in cooperation with the gas transmission mechanism 200 and the circulation mechanism 300, so that the cold air in the inner cavity of the refrigerated tank 105 is filled more evenly and fully. The clamping connection between the through pipe 202 and the support frame 203 allows the through pipe 202 to continuously ventilate at a fixed position, providing a continuous air source for the refrigerated tank 105, and improving the refrigerated storage effect of agricultural products. The fixed connection between the outer shell 101 and the support frame 203 ensures that people will not be affected by the refrigerated tank 105 located inside when they touch the outer shell 101, thereby reducing the risk of frostbite. The side plate 301 and the threaded rod 30 2 is fixedly connected, so that the slider 303 can stabilize the threaded displacement, and the fixed sleeve of the crank handle 304 and the screw rod 302 can adjust the tension of the elastic belt 306 through the tensioning rod 305, and further change the contact degree between the elastic belt 306 and the impeller 312 plug shaft, thereby causing the impeller 312 speed to change, and the cold air disturbance speed to change synchronously, overcoming the disadvantage of the adaptation of the cold air output surface and the disturbance action surface, so that the cold air filling speed can meet the refrigerated storage needs of different types of agricultural products according to different process requirements, reflecting the refrigeration effect of the refrigeration tank 105.

[0031] Furthermore, a guide shaft 307 is sleeved on the inner side of the elastic belt 306, and the side of the guide shaft 307 is fixedly connected to the outer shell 101, and a sleeve shaft 308 is sleeved on the top of the elastic belt 306, and one end of the sleeve shaft 308 is fixedly connected to the drive motor 309, and a positioning frame 310 is fixedly sleeved on the surface of the drive motor 309, and the side of the positioning frame 310 is fixedly connected to the outer shell 101.

[0032] Preferably, the sleeve arrangement of the guide shaft 307 and the elastic belt 306 limits the middle section of the elastic belt 306, and the elastic belt 306 will not get knotted or twisted during adjustment, while also ensuring the stable and continuous speed adjustment function of the impeller 312. The fixed connection between the sleeve shaft 308 and the drive motor 309 allows the rotating sleeve shaft 308 to provide stable rotational support for the top of the elastic belt 306. The fixed connection between the positioning frame 310 and the outer shell 101 allows the drive motor 309 to remain stable during operation, and the rotational support effect of the sleeve shaft 308 is more significant, while also ensuring a relatively stable turbulent flow function in the inner cavity of the refrigerated tank 105.

[0033] It should be noted that a diverter plate 311 is inserted into the side of the impeller 312 . The diverter plate 311 is provided with a plurality of through holes, which are arranged at equal intervals on the surface of the diverter plate 311 .

[0034] The plurality of through holes formed in the diverter plate 311 can evenly disperse the cold air gathered on the side of the refrigeration tank 105, thereby improving the refrigeration effect and saving cold air resources.

[0035] Example 2

[0036] Reference Figure 2-3 , which is the second embodiment of the present utility model. Different from the previous embodiment, this embodiment provides relevant parts for achieving the effect of uniformly dispersing the disturbance of cold air.

[0037] Specifically, a push rod 313 is fixedly connected to the inner side of the housing 101 . There are two push rods 313 , and a gap is left between the two push rods 313 .

[0038] Furthermore, the arrangement of two top rods 313 with a gap therebetween allows the cold air at the top of the refrigerated tank 105 to be evenly dispersed by the top rods 313. The fine shrinkage holes opened in the top rods 313 divide the cold air into small parts, thereby avoiding excessive cooling accumulation that affects the refrigeration efficiency.

[0039] Preferably, the gas delivery mechanism 200 further includes a gas delivery port 201 , and an end surface of the gas delivery port 201 is connected to the through pipe 202 .

[0040] The communication between the gas transmission port 201 and the through pipe 202 enables the through pipe 202 to continuously transport cold air, and the refrigerated storage effect of the agricultural products is long-lasting and continuous.

[0041] Example 3

[0042] Reference Figure 2-5 , which is the third embodiment of the present utility model. Different from the previous embodiment, this embodiment provides relevant parts for achieving the stable placement effect of the refrigeration tank 105.

[0043] Specifically, a column 106 is fixedly connected to the bottom of the refrigeration tank 105 , a lower surface of the column 106 is plugged into the outer shell 101 , and the center of the column 106 remains coincident with the outer shell 101 .

[0044] Furthermore, the fixed connection between the column 106 and the refrigerated tank 105 allows the refrigerated tank 105 to be stably placed in the inner cavity of the shell 101, while also allowing the internal cold air to remain relatively still during transportation, reducing the irregular movement of the cold air.

[0045] Preferably, the bottom of the shell 101 is adapted to be installed with support legs 102, which are symmetrically distributed at the corners of the shell 101, and the top of the shell 101 is connected to a feeding port 103, the outer side of the refrigerated tank 105 is fixedly connected to the inner column 104, and one side of the inner column 104 is snap-connected to the shell 101.

[0046] Among them, the adaptive installation of the support legs 102 and the outer shell 101 provides stable support for the outer shell 101 and ensures the stable transportation of cold air. The connection between the feeding port 103 and the outer shell 101 allows agricultural products to be directly put into the inner cavity of the refrigerated tank 105, which is convenient for refrigerated storage. The clamping connection between the inner column 104 and the outer shell 101 allows the refrigerated tank 105 to be stably placed.

[0047] Working principle: First, put the agricultural products into the refrigerated tank 105 through the feeding port 103, then connect the air outlet 201 with the external cold air source, and the through pipe 202 helps the cold air source to be transmitted into the refrigerated tank 105. At the same time, turn the crank 304 to make the threaded rod 302 rotate synchronously, and the slider 303 and the tension rod 305 move accordingly. Then, the elastic belt 306 is connected between the sleeve shaft 308 and the tension rod 305, and then the drive motor 309 is started. The guide shaft 308 moves at the appropriate position. The position of the elastic belt 306 is limited and supported, and then the elastic belt 306 will change the degree of fit with the outer surface of the sleeve shaft 308 under the lateral adjustment of the tensioning rod 305. This change will cause the speed of the impeller 312 to change, and the cold air in the inner cavity of the refrigerated tank 105 will be disturbed and spread, helping the cold air to fill quickly. The diverter plate 311 close to the inner wall of the outer shell 101 and the top rod 313 inserted in the inner cavity of the outer shell 101 are used for the rapid division of the cold air mass, thereby improving the refrigerated storage efficiency of agricultural products.
