Description

Technical Field

[0001] The invention relates to the technical field of low-temperature refrigeration of seeds, and in particular to a low-temperature refrigeration device for pea seeds. Background Art

[0002] In order to ensure the quality and yield of next year's sowing, pea seeds need to be stored effectively for a long time. Low temperature refrigeration is a very effective storage method, which can effectively extend the shelf life of seeds and maintain their germination ability.

[0003] However, the humidity in the cold storage environment may cause the seeds to absorb moisture, which may lead to mildew or premature germination. Although the use of packaging materials with good moisture-proof properties (such as aluminum foil bags and composite film bags) can effectively prevent the intrusion of external moisture, completely sealed packaging will cause the seeds to be in an oxygen-deficient state, inhibiting their respiration and affecting the long-term preservation effect. Therefore, packaging materials that are both moisture-proof and moderately breathable are usually selected to allow a small amount of gas exchange and prevent excessive moisture from entering. However, this still causes some moisture to condense into water and adhere to the surface of the packaging bag and pea seeds, which will cause the pea seeds to still absorb moisture, mildew or germinate during cold storage, which will not only cause economic losses, but also affect the stability and sustainability of agricultural production. Summary of the invention

[0004] In order to overcome the disadvantages of pea seeds absorbing moisture, becoming moldy or germinating during cold storage, the present invention provides a low-temperature cold storage device for pea seeds.

When the opening and closing plate is rotated to open, the liquid storage tank is connected to the guide channel, and the other side of the sliding frame is movably connected to the opening and closing plate.

[0011] As a preferred technical solution of the present invention, a movable groove is provided on one side of the sliding frame close to the opening and closing plate, and the sliding frame is movably connected to the opening and closing plate through the movable groove.

At the same time, the structural design of the cooling rack can prevent the condensed water from flowing back and falling onto the surface of the pea seeds and the packaging bag thereof.

[0016] The carrier of the present invention not only swings back and forth intermittently to shake off water droplets, but also pulls a rotating plate on one side to change the wind direction, so that all cold wind is concentrated and directed to the side of the carrier that is tilted downward, thereby increasing the wind force, thereby accelerating the falling of water droplets on the surface of the pea seeds and the packaging bags thereof, and enhancing the dehumidification effect.

The serial numbers of the parts in this article, such as first, second, etc., are only used to distinguish the objects described and do not have any order or technical meaning. The words such as connection and coupling in this application include direct and indirect connection (coupling) unless otherwise specified.

[0036] Embodiment 1: A pea seed low temperature refrigeration device, such as Figure 1-Figure 6As shown, a refrigerator 101 is included, the front side of the refrigerator 101 is rotatably connected to a door 102, a cooling rack 103 is fixedly connected inside the refrigerator 101, the cooling rack 103 is provided with a plurality of inclined surfaces inclined toward the lower left, a cooling fan 104 is fixedly connected to the top side of the cooling rack 103, three connected air ducts 105 are fixedly connected to the left side of the cooling rack 103 from front to back, the air outlet of the cooling fan 104 is connected to the top of the air duct 105, and the cooling rack 103 is provided with two bearings. The pea seeds are placed in a moisture-proof and moderately breathable packaging bag, and then the packaging bag is placed on the carrier 106. Three guide plates 107 arranged in a stepped manner are fixedly connected to the left side of the bottom of each inclined surface of the cooling rack 103. The coolant flows along the inclined surface of the cooling rack 103 to the lower left to the guide plate 107. The cooling rack 103 is fixedly connected to three air outlet pipes 108 on one side close to each carrier 106. The air outlet pipes 108 are located on the adjacent carrier 106. The cooling rack 103 has three longitudinally distributed flow guide cavities 109 on the left side, the flow guide cavities 109 are inclined forward and downward, and the flow guide plate 107 is used to guide the coolant to the left into the adjacent flow guide cavities 109. The inner bottom of the refrigerator 101 is provided with a liquid storage tank 110. The left front part of the cooling rack 103 has a flow guide channel 111, and the flow guide cavity 109 and the liquid storage tank 110 are both connected to the flow guide channel 111. The cooling rack 103 has a left side that is opposite to the air outlet duct 108. The corresponding vent 112 is provided, the air outlet duct 108 is connected to the adjacent air guide duct 105 through the vent 112, a liquid port 113 is provided on one side of the cooling rack 103 close to the adjacent air outlet ducts 108, the liquid port 113 is connected to the adjacent guide cavity 109, the coolant on the guide plate 107 is discharged into the guide cavity 109 through the liquid port 113, and three longitudinally distributed exhaust ports 114 are provided on the right side of the refrigerator 101, and cold air and moisture are discharged through the exhaust ports 114.

[0037] First, put the pea seeds into a packaging bag that is both moisture-proof and moderately breathable, then open the box door 102, place the pea seeds with the packaging bag on the support rack 106, then close the box door 102, start the air cooler 104, and the dry and cold airflow flows downward along the air guide pipe 105, and then enters the air outlet pipe 108 through each vent 112. The cold air in the air outlet pipe 108 blows upward to blow off the water droplets on the surface of the pea seeds and the packaging bag. The blown water droplets fall on the inclined surface of the cooling rack 103 close to the air outlet pipe 108, and then flow to the lower left to the liquid port 113 and enter the guide cavity 109 At the same time, the cold wind carries the moisture in the box upward. When part of the moisture contacts the cooling rack 103, it condenses into water droplets and adheres to the inclined surface of the cooling rack 103 facing away from the air outlet 108. It flows to the lower left along the cooling rack 103 to the guide plate 107, and then flows to the lower left along the guide plate 107 into the guide cavity 109. The coolant flowing into the guide cavity 109 flows forward and downward into the guide channel 111, and finally flows downward along the guide channel 111 into the liquid storage tank 110. The remaining moisture is discharged out of the box from the exhaust port 114 along with the cold wind.

[0038] In summary, the present invention refrigerates the pea seeds by passing cold air, and uses the cold air to blow off the water droplets condensed on the surface of the pea seeds and the packaging bags, and condenses part of the moisture into water droplets through the cooling rack 103, and forms a drainage channel through the guide plate 107, the cooling rack 103 and the liquid port 113, the guide cavity 109, and the guide channel 111 therein, so that the condensed water is collected downward along the drainage channel into the liquid storage tank 110. In this way, the condensed water formed by the moisture in the box is prevented from adhering to the surface of the pea seeds and the packaging bags during refrigeration, and the seeds are effectively prevented from absorbing moisture, mildewing or germination.

[0039] The present invention provides an exhaust port 114 so that the remaining moisture is discharged together with the cold air, and the cooling rack 103 is tilted so that the condensed water flowing downward and the moisture flowing upward can be discharged according to their own characteristics, thereby achieving the effect of effectively discharging the moisture and condensed water in the refrigerator 101. At the same time, the structural design of the cooling rack 103 can prevent the condensed water from flowing back and falling onto the surface of the pea seeds and their packaging bags.

[0040] like Figure 7-Figure 9As shown, four telescopic frames 201 are also included, the supporting frame 106 is rotatably connected to the cooling frame 103, every two telescopic frames 201 are respectively distributed on the left and right parts of the rear side of a supporting frame 106, the telescopic frame 201 is rotatably connected to the adjacent supporting frame 106, a rotating frame 202 is rotatably connected between the lower part of the telescopic frame 201 and the cooling frame 103, a spring 203 is fixedly connected between the rotating frame 202 and the cooling frame 103, twelve rotating plates 204 are rotatably connected between the front and rear air outlet pipes 108 on the same side, the rotating frame 202 is fixedly connected to the adjacent rotating plates 204, and the six rotating plates 204 on the adjacent left side and the six rotating plates 204 on the adjacent right side are rotatably connected with connecting rods 205 symmetrically distributed along the front and rear of the rotating plates 204.

[0041] like Fig.10 As shown, it also includes a rotating frame 301 corresponding to the supporting frame 106, the rotating frame 301 is fixedly connected to the middle of the rear side of the corresponding supporting frame 106, and the rear outer wall of the cold storage box 101 is fixedly connected to the cylinder 302 corresponding to the rotating frame 301, and the telescopic rod of the cylinder 302 is rotatably connected to the corresponding rotating frame 301.

[0042] In order to accelerate the falling of water drops on the surface of pea seeds and their packaging bags, the telescopic rod of the cylinder 302 is controlled to be intermittently extended and retracted, and the telescopic rod of the cylinder 302 drives the supporting frame 106 to swing back and forth clockwise and counterclockwise intermittently through the rotating frame 301, thereby shaking off the water drops on the surface of the pea seeds and their packaging bags.

[0043] When the support frame 106 is placed horizontally, the rotating plates 204 on the left and right sides are both facing vertically upward, and the telescopic frames 201 are both stretched to the maximum limit. When the support frame 106 swings clockwise, the right side of the support frame 106 will only compress the telescopic frame 201 on the right and drive the telescopic frame 201 on the right to rotate alone. The left side of the support frame 106 pulls the rotating frame 202 on the left to rotate through the telescopic frame 201 on the left, and the spring 203 is deformed. The rotating frame 202 on the left cooperates with the connecting rod 205 on the left to drive the rotating plate 204 on the left to swing clockwise, thereby guiding the cold air on the left side toward the upper right to the support frame 106 tilted toward the lower right. In this way, all the cold air is concentrated and directed to the right side, and the wind force is strengthened to make the water droplets on the right side easier to fall. Similarly, when the support frame 106 swings counterclockwise, the cold air on the right side will be guided toward the upper left to the support frame 106 tilted toward the lower left. In this way, all the cold air is concentrated and directed to the left side, and the wind force is strengthened to make the water droplets on the left side easier to fall.

[0044] In summary, while the support frame 106 of the present invention intermittently swings back and forth to shake off water droplets, it also pulls the rotating plate 204 on one side to change the wind direction, so that all the cold air is concentrated and directed to the side of the support frame 106 that is tilted downward, thereby increasing the wind force, thereby accelerating the falling of water droplets on the surface of the pea seeds and their packaging bags, and enhancing the dehumidification effect.

[0045] like Fig.11 and Fig.13 As shown, it also includes an opening and closing frame 401, which is rotatably connected to the upper part between each air duct 105, and a torsion spring 402 is fixed between the opening and closing frame 401 and the air duct 105 on the rear side. The front side of the opening and closing frame 401 is rotatably connected to a push-pull rod 403, and the side of the cooling frame 103 close to the liquid storage tank 110 is slidably connected to a sliding frame 404 along the up and down directions. The upper side of the sliding frame 404 is rotatably connected to the push-pull rod 403, and the front side of the liquid storage tank 110 is rotatably connected to an opening and closing plate 405. When the opening and closing plate 405 is rotated to open, the liquid storage tank 110 is connected to the guide channel 111, and a movable groove is opened on the lower side of the sliding frame 404, and the sliding frame 404 is movably connected to the opening and closing plate 405 through the movable groove.

[0046] When the air cooler 104 is working, the cold air enters the air duct 105 and blows the opening and closing frame 401 downward, the torsion spring 402 is deformed, the opening and closing frame 401 pushes the sliding frame 404 to slide downward through the push-pull rod 403, and the sliding frame 404 pushes the opening and closing plate 405 to open through the movable groove, so that the condensate can flow into the liquid storage tank 110. When the air cooler 104 stops working, the torsion spring 402 is reset, the opening and closing frame 401 pulls the sliding frame 404 to slide upward through the push-pull rod 403, and the sliding frame 404 pulls the opening and closing plate 405 to close through the movable groove, preventing the water in the liquid storage tank 110 from evaporating into moisture and flowing back into the cold storage tank 101 when the air cooler 104 does not work and the outside temperature rises.

[0047] like Figure 14-15 As shown, it also includes an air guide block 501 corresponding to the air outlet pipe 108, the air guide block 501 is fixedly connected to the right side of the top of the corresponding air outlet pipe 108, the air guide block 501 is used to guide the gas to the exhaust port 114, and accelerate the discharge of moisture. A fixing frame 502 corresponding to the exhaust port 114 is fixedly connected to the right side of the refrigerator 101, and a baffle 503 is rotatably connected to one side of the refrigerator 101 close to the corresponding exhaust port 114, and the baffle 503 is located above the adjacent fixing frame 502, and the baffle 503 contacts and cooperates with the adjacent fixing frame 502 to block the corresponding exhaust port 114.

[0048] The present invention guides part of the cold air to the exhaust port 114 through the air guide block 501, accelerates the discharge of moisture, and blows the baffle 503 upward when the cold air and moisture are discharged, so that the baffle 503 is separated from the fixing frame 502, thereby not blocking the exhaust port 114. When the air cooler 104 stops working, the rotating plate 204 swings downward under the action of gravity until it contacts the fixing frame 502, thereby blocking the exhaust port 114. In this way, when the air cooler 104 is not working, the cold air inside is prevented from being discharged and affecting the refrigeration effect, while preventing external moisture from entering.

[0049] Although the present disclosure has been shown and described with reference to specific exemplary embodiments of the present disclosure, it should be understood by those skilled in the art that various changes in form and details may be made to the present disclosure without departing from the spirit and scope of the present disclosure as defined by the appended claims and their equivalents. Therefore, the scope of the present disclosure should not be limited to the above-mentioned embodiments, but should be determined not only by the appended claims, but also by the equivalents of the appended claims.
