Description

Technical Field

[0001] The invention belongs to the technical field of refrigeration equipment, and in particular relates to an environmentally friendly and energy-saving field refrigeration equipment. Background Art

[0002] With the acceleration of globalization, trade in agricultural products between countries has become more frequent. Consumers' dietary needs are no longer limited to local or national traditional foods, but they have begun to enjoy agricultural products from all over the world. Most agricultural products (such as fruits, vegetables, etc.) tend to spoil quickly at room temperature. Cold chain management of agricultural products through refrigeration equipment can extend their shelf life, reduce the risk of rot and spoilage, and ensure that food maintains its nutritional value and taste during long-term transportation. The popularization of cold chain technology has made the production, processing, transportation and other links of agricultural products more efficient, enabling agricultural products to circulate across regions and seasons, and promoting the industrialization of agriculture. The application of refrigeration equipment in agriculture is not limited to fresh agricultural products, but also includes grain, seeds, flowers and other fields, which helps to promote the extension of the agricultural industry chain and the increase of added value of agricultural products.

[0003] When refrigerating and transporting agricultural products in the field, cold storage is needed to cool them. Since the entire cold storage space is large, fans are often needed to blow cold air throughout the space. Although fans can help the cold air flow, when the cold storage space is large or the layout is complex, fans cannot effectively distribute the cold air evenly to each area, especially in the corners far away from the fans, the temperature will be too high, affecting the quality of the stored items. In addition, some areas will be overcooled or even frosted due to excessive wind speed or direct blowing of cold air, causing product freezing or quality loss, while other places will have high temperatures due to insufficient air circulation, reducing the cooling effect. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide an environmentally friendly and energy-saving field refrigeration equipment.

[0005] The technical solution adopted to solve the above technical problems is: an environmentally friendly and energy-saving field refrigeration equipment, including a device seat, a card slot is provided on the top of the device seat, the device seat is slidably connected to the refrigeration shell through the card slot, a support platform is provided between the device seat and the device seat, the support platform is fixedly connected to the device seat, a uniform cooling structure is provided on the top of the support platform, an air inlet is provided on one side of the refrigeration shell, a number of partitions are provided in the air inlet, and an adaptive spoiler mechanism is provided between the several partitions, a refrigeration host is provided on one side of the air inlet, and the refrigeration host is fixedly installed on the device seat.

[0006] Through the above technical solution, during the refrigeration process of the cold storage, the temperature distribution often becomes uneven. Through the alternating up and down cycles, the agricultural products can get uniform cold air circulation in the device. In this way, the agricultural products will not encounter the problem of too high or too low temperature due to staying in a fixed position, ensuring more stable temperature control.

[0007] Furthermore, a plurality of hollow grooves are provided through the top of the support platform, an L-shaped support plate is provided at the diagonal position of the hollow groove, the L-shaped support plate is fixedly connected to the support platform, the uniform cooling structure is rotatably connected to the L-shaped support plate, and a door panel is hinged on the side of the refrigeration shell away from the air inlet, and a control panel is provided on one side of the door panel.

[0008] Through the above technical solution, as the placement basket is alternately raised and lowered, the agricultural products can receive cold air more evenly, thereby reducing the temperature more efficiently. This dynamic adjustment helps to reduce the existence of areas with excessively high temperatures in the cold storage, avoid frequent activation of the refrigeration system due to uneven cooling in certain areas, and reduce energy consumption.

[0009] Furthermore, the adaptive spoiler mechanism includes a fixed frame, which is fixed to the refrigeration shell, and the top of the fixed frame is rotatably connected to a rotating shaft, a spoiler is welded to one side of the rotating shaft, the interior of the rotating shaft is a hollow structure, and the rotating shaft is in an open state on the side away from the spoiler, the interior of the rotating shaft is rotatably connected to a rotating rod, the other end of the rotating rod is slidably connected to a wedge plate, the other end of the wedge plate is rotatably connected to the fixed frame, the side of the fixed frame away from the rotating shaft is rotatably connected to an impeller, the impeller connecting shaft is rotatably connected to the fixed frame, and the through end of the impeller connecting shaft is fixedly connected to the wedge plate.

[0010] Through the above technical solution, by setting an adaptive spoiler mechanism at the cold air inlet, the cold air can cover all areas in the cold storage, avoiding the cold air being concentrated in a certain area and causing uneven temperature. The disturbed cold air can help avoid the accumulation of excessive humidity and reduce the growth of mold in the cold storage and the risk of rotting of agricultural products.

[0011] Furthermore, the uniform cooling structure includes several first connecting plates and third connecting plates, which are respectively rotatably connected to the L-shaped support plates at the diagonals of the hollow groove. The other end of the first connecting plate is rotatably connected to the second connecting plate, a slide plate is welded on one side of the third connecting plate, and the end of the third connecting plate away from the L-shaped support plate is rotatably connected to the fourth connecting plate.

[0012] Furthermore, a connecting frame is rotatably connected between the fourth connecting plate and the end of the second connecting plate away from the first connecting plate, and a placement basket is installed on the connecting frame through a pin. Ventilation grooves are opened on both sides of the top of the placement basket. The placement basket is located inside the hollow groove, and the placement basket is set at a ninety-degree angle with the support platform and does not intersect.

[0013] Through the above technical solution, cold air can contact all agricultural products more evenly, improving the heat exchange efficiency between air and agricultural products, accelerating the cooling process, and improving the overall refrigeration efficiency of the cold storage. In addition, the uniform air circulation reduces the burden on the cold storage equipment, so that the refrigeration equipment does not need to be started and stopped frequently, thereby achieving energy-saving effects.

[0014] Furthermore, a plurality of fixing seats are fixedly connected to the top surface of the support platform, and the fixing seats are linearly symmetrically distributed between each other. A chain assembly is rotatably connected between each other, and the chain assembly includes a chain and a plurality of sprockets. The sprocket connecting shaft in the chain assembly is rotatably connected to the fixing seat.

[0015] Furthermore, an L-shaped turn plate is fixedly connected to the through end of the sprocket connecting shaft in the chain assembly, and the L-shaped turn plates on both sides are arranged in opposite directions, and the long end of the L-shaped turn plate has the same height as the fixed seat, and the other end of the L-shaped turn plate is located inside the slide plate, and one end of the L-shaped turn plate is located inside the slide plate and is slidably connected to the slide plate.

[0016] Through the above technical solution, the phenomenon of frost or ice formation on cold storage equipment and storage surfaces can be reduced, the impact of frost accumulation on cold storage equipment can be avoided, and the risk of ice formation on the surface of agricultural products can be reduced, thereby maintaining product quality.

[0017] Furthermore, a through groove is opened through the center of one side of the top surface of the support platform, and a synchronous belt assembly is arranged in the through groove. The synchronous belt assembly includes a synchronous belt and a synchronous wheel. A synchronous wheel in the synchronous belt assembly is rotatably connected to the support platform, and another synchronous wheel in the synchronous belt assembly is fixedly connected to a sprocket connecting shaft in the chain assembly. A motor is installed on one side of the bottom of the support platform, and the output end of the motor is rotatably connected to the support platform, and the through end of the motor is fixedly connected to a synchronous wheel in the synchronous belt assembly.

[0018] Through the above technical solution, different agricultural products have different requirements for temperature and humidity. The dynamically lifting placement basket can adjust the storage level according to the characteristics of the agricultural products, making the environment in different areas of the cold storage more suitable, thereby helping to extend the shelf life of agricultural products.

[0019] The beneficial effects of the present invention are as follows: (1) The present invention adopts an adaptive spoiler mechanism. Cold air enters the device seat and the refrigeration shell through the air inlet. When the cold air passes through the dividing channel formed by several partitions, the cold air drives the impeller to rotate after passing through the inclined blades of the impeller, so that the wedge plate rotates synchronously, causing the rotating rod and the wedge plate to slide relative to each other. At the same time, the rotating rod rotates synchronously with it, so that the rotating shaft rotates up and down repeatedly relative to the fixed frame, and then the spoiler swings up and down in a cycle. Under the action of the up and down swinging of the spoiler, the cold air can flow to different heights and areas, avoiding the occurrence of air stagnation and dead corners. The air flow helps to remove moisture and harmful gases in the cold storage, keep the air fresh, and maintain a stable low-temperature environment, thereby extending the shelf life of agricultural products. (2) The present invention adopts a uniform cooling structure. The operation of the motor drives the synchronous belt assembly to transmit, so that the chain assembly transmits, and the sprocket in the chain assembly rotates, driving the L-shaped rotating plates on both sides of the fixed seat to rotate at the same time, prompting the end of the L-shaped rotating plate away from the fixed seat to rotate and slide back and forth inside the slide plate, so that the slide plate swings up and down, and then prompting the third connecting plate to swing up and down synchronously with the slide plate. At this time, the fourth connecting plate and the third connecting plate rotate relative to each other, and the connecting frame is lifted up and down, so that the placement basket moves up and down inside the hollow groove, and the L-shaped rotating plates on both sides of the fixed seat are set in opposite directions, so as to realize the placement basket in the two hollow grooves to perform alternating up and down cyclic lifting and lowering movements. The storage rack can help the agricultural products form a closed environment between the device seat and the refrigeration shell, obtain uniform cold air circulation, thereby breaking the stillness of the air layer, promoting air flow, preventing the formation of moisture or frost in the cold storage, and reducing the impact of frost on the agricultural products.

During the refrigeration process of the cold storage, the temperature distribution often becomes uneven. By alternating up and down cycles, the agricultural products can obtain uniform cold air circulation in the device. In this way, the agricultural products will not suffer from the problem of too high or too low temperature due to staying in a fixed position. To ensure more stable temperature control, a connecting frame 24 is rotatably connected between the fourth connecting plate 26, which is away from one end of the third connecting plate 25, and the second connecting plate 23, which is away from one end of the first connecting plate 22, is installed on the connecting frame 24 through a pin 20. A plurality of fixing seats 29 are fixedly connected to the top surface of the support platform 16. A through groove 31 is opened at the center of one side of the top surface of the support platform 16. A synchronous belt assembly 32 is arranged in the through groove 31. The synchronous belt assembly 32 includes a synchronous belt and a synchronous wheel. A synchronous wheel in the synchronous belt assembly 32 is rotatably connected to the support platform 16, and another synchronous wheel in the synchronous belt assembly 32 is fixedly connected to a sprocket connecting shaft in the chain assembly 30. It can reduce the phenomenon of frost or ice on the cold storage equipment and the storage surface, avoid the impact of frost accumulation on the cold storage equipment, and reduce the risk of ice on the surface of agricultural products, thereby maintaining product quality.

[0024] like Figure 2-Figure 10As shown, several fixed seats 29 are linearly symmetrically distributed between each other, and chain assemblies 30 are rotatably connected between each two of the fixed seats 29. The sprocket connecting shaft in the chain assembly 30 is fixedly connected to an L-shaped rotating plate 28 at the end. The L-shaped rotating plates 28 on both sides are arranged in opposite directions, and the long ends of the L-shaped rotating plates 28 are at the same height as the fixed seats 29. The other end of the L-shaped rotating plate 28 is located inside the slide plate 27, and the L-shaped rotating plate 28 is located inside the slide plate 27 and is slidably connected to the slide plate 27 at one end. The chain assembly 30 includes a chain and several sprockets. The sprocket connecting shaft in the chain assembly 30 is rotatably connected to the fixed seat 29. Ventilation slots 21 are opened on both sides of the top of the placement basket 19. The placement basket 19 is located inside the hollow groove 17. As the placement basket 19 is alternately raised and lowered, the agricultural products can receive cold air more evenly, thereby reducing the temperature more efficiently. This dynamic Dynamic adjustment helps to reduce the existence of areas with excessively high temperatures in the cold storage, avoids frequent activation of the refrigeration system due to uneven cooling in certain areas, and reduces energy consumption. The placement basket 19 and the support platform 16 are arranged at a ninety-degree angle and do not intersect. Different agricultural products have different requirements for temperature and humidity. The dynamically lifting placement basket 19 can adjust the storage level according to the characteristics of the agricultural products, making the environment in different areas of the cold storage more suitable, thereby helping to extend the shelf life of the agricultural products. Several hollow grooves 17 are opened through the top of the support platform 16, and L-shaped support plates 18 are set at the diagonals of the hollow grooves 17. The L-shaped support plates 18 are fixedly connected to the support platform 16, and the uniform cooling structure 34 is rotatably connected to the L-shaped support plates 18. The refrigeration shell 2 is hinged with a door panel 3 on the side away from the air inlet 5, and a control panel 6 is set on one side of the door panel 3. The air inlet 5 is opened on one side of the refrigeration shell 2.

[0025] like Figures 1-15As shown, a number of partitions 7 are set in the air inlet 5, and an adaptive spoiler mechanism 8 is set between the partitions 7. By setting the adaptive spoiler mechanism 8 at the air inlet 5, the cold air can cover various areas in the cold storage, avoiding the cold air from being concentrated in a certain area to cause uneven temperature, and the disturbed cold air can help avoid the accumulation of excessive humidity, reduce the growth of mold in the cold storage and the risk of rotting of agricultural products, the adaptive spoiler mechanism 8 includes a fixing frame 9, the fixing frame 9 is fixed to the refrigeration shell 2, the top of the fixing frame 9 is rotatably connected to the rotating shaft 10, and a spoiler 11 is welded to one side of the rotating shaft 10. The interior of the rotating shaft 10 is a hollow structure, and the side of the rotating shaft 10 away from the spoiler 11 is in an open state, and the internal rotation of the rotating shaft 10 is connected to The rotating rod 14, the other end of the rotating rod 14 is slidably connected with a wedge plate 13, the other end of the wedge plate 13 is rotatably connected to the fixed frame 9, and the fixed frame 9 is rotatably connected to the impeller 12 on the side away from the rotating shaft 10. The impeller 12 connecting shaft is rotatably connected to the fixed frame 9, and the cold air can contact all agricultural products more evenly, thereby improving the heat exchange efficiency between air and agricultural products, accelerating the cooling process, and improving the overall refrigeration efficiency of the cold storage. In addition, the uniform air circulation reduces the burden on the cold storage equipment, so that the refrigeration equipment does not need to be frequently started and stopped, thereby achieving energy-saving effects. The impeller 12 connecting shaft is fixedly connected to the wedge plate 13 at the through end, and a refrigeration host 4 is provided on one side of the air inlet 5, and the refrigeration host 4 is fixed to the device base 1.

[0026] The working principle of this embodiment is as follows: first, the entire device is installed, the refrigeration shell 2 is slidably engaged with the device base 1 through the slot 15, and then the refrigeration host 4, the refrigeration shell 2 and the door panel 3 are respectively installed and fixed to the device base 1 and the refrigeration shell 2, and then connected and fixed to the components inside the device base 1 and the refrigeration shell 2 by using wires.

[0027] The staff collects the agricultural products and places them in the placement basket 19 for collection and sorting, opens the door panel 3, and then places the agricultural products and the placement basket 19 on the connecting frame 24, uses the pin 20 to limit and fix them, and then closes the door panel 3, operates the control panel 6, so that the refrigeration host 4 and the motor 33 inside the refrigeration shell 2 run at the same time. The refrigeration host 4 runs through the four main steps of compression, condensation, expansion and evaporation, and repeats them continuously in the closed cycle of the device base 1 and the refrigeration shell 2, so that the refrigerant is converted from a low temperature and low pressure state to a high temperature and high pressure state and releases heat, and then absorbs heat through expansion and evaporation, finally achieving cooling and forming a closed environment between the device base 1 and the refrigeration shell 2.

[0028] During the cooling process, cold air enters the device base 1 and the refrigeration shell 2 through the air inlet 5. When the cold air passes through the dividing channel formed by several partitions 7, the cold air passes through the inclined blades of the impeller 12, driving the impeller 12 to rotate, causing the wedge plate 13 to rotate synchronously, prompting the rotating rod 14 and the wedge plate 13 to slide relative to each other, and at the same time, the rotating rod 14 rotates synchronously with it, so that the rotating shaft 10 rotates up and down repeatedly relative to the fixing frame 9, and then the spoiler 11 swings up and down in a cycle, which can evenly distribute the cold air in the space, avoid the cold air from concentrating in a certain position, and reduce the temperature difference.

[0029] The operation of the motor 33 drives the synchronous belt assembly 32 to transmit, so that the chain assembly 30 is transmitted, and the sprocket in the chain assembly 30 rotates, driving the L-shaped rotating plates 28 on both sides of the fixed seat 29 to rotate simultaneously, causing the end of the L-shaped rotating plate 28 away from the fixed seat 29 to rotate and slide back and forth inside the slide plate 27, thereby causing the slide plate 27 to swing up and down, and then causing the third connecting plate 25 to swing up and down synchronously with the slide plate 27. At this time, the fourth connecting plate 26 and the third connecting plate 25 rotate relative to each other, pushing up the connecting frame 24 up and down, so that the placement basket 19 moves up and down inside the hollow groove 17, and the L-shaped rotating plates 28 on both sides of the fixed seat 29 are set in opposite directions, thereby realizing the placement basket 19 in the two hollow grooves 17 to perform alternating up and down cyclic lifting and lowering motion. The agricultural products in the placement basket 19 can receive the cold air more evenly, thereby reducing the temperature more efficiently. This dynamic adjustment helps to reduce the existence of areas with excessively high temperatures in the cold storage, avoid frequent activation of the refrigeration system due to uneven cold air in certain areas, and reduce energy consumption.

[0030] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
