Description

Technical Field

[0001] The present invention relates to the technical field of low-temperature cold storage of seeds, and particularly to a low-temperature cold storage device for pea seeds. Background Art

[0002] In order to ensure the quality and yield of sowing in the coming year, it is necessary to store pea seeds effectively for a long time. Low-temperature cold storage is a very effective preservation method, which can effectively extend the preservation period of seeds and maintain their germination ability.

[0003] However, the moisture in the cold storage environment may cause the seeds to absorb moisture, which may then lead to mildew or premature germination. Although using packaging materials with good moisture-proof performance (such as aluminum foil bags and composite film bags) can effectively prevent external moisture from invading, a completely sealed package 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 can both prevent moisture and allow moderate ventilation are usually selected, which allow a small amount of gas exchange and prevent too much water 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 still cause the pea seeds to absorb moisture, mildew or germinate during cold storage. This 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, mildewing or germinating during cold storage, the present invention provides a low-temperature cold storage device for pea seeds.

[0006] As a preferred technical solution of the present invention, the air outlet pipes are located below the adjacent carrier racks, and the flow guide cavity is inclined towards the flow guide channel side.

[0007] As a preferred technical solution of the present invention, the carrier rack is rotatably connected to the cooling rack, and a swing assembly for pushing the carrier rack to rotate is provided on the outer wall of the refrigerated box.

[0008] As a preferred technical solution of the present invention, it further includes at least two telescopic racks. The telescopic racks are rotatably connected to the adjacent carrier racks. A rotating rack is rotatably connected between the telescopic racks and the cooling rack. A spring is fixedly connected between the rotating rack and the cooling rack. A plurality of rotating plates are rotatably connected between the air outlet pipes on the same side. The rotating rack is fixedly connected to the adjacent rotating plates. Connecting rods symmetrically distributed along the rotating plates are rotatably connected between the plurality of rotating plates on the adjacent side.

[0009] As a preferred technical solution of the present invention, the swing assembly includes a rotating frame corresponding to the carrier rack. The rotating frame is fixedly connected to the corresponding carrier rack. A cylinder corresponding to the rotating frame is fixedly connected to the outer wall of the refrigerated box. The telescopic rod of the cylinder is rotatably connected to the corresponding rotating frame.

[0010] As a preferred technical solution of the present invention, it further includes an opening and closing frame. The opening and closing frame is rotatably connected between the air guide pipes. A torsion spring is fixedly connected between the opening and closing frame and one side of the air guide pipe. A push-pull rod is rotatably connected to the opening and closing frame. A sliding frame is slidably connected to one side of the cooling rack close to the liquid storage tank. One side of the sliding frame is rotatably connected to the push-pull rod. An opening and closing plate is rotatably connected to one side of the liquid storage tank close to the sliding frame. When the opening and closing plate is rotated and opened, the liquid storage tank is communicated with the diversion channel. 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, an activity groove is opened on one side of the sliding frame close to the opening and closing plate. The sliding frame is movably connected to the opening and closing plate through the activity groove.

[0012] As a preferred technical solution of the present invention, it further includes an air guide block corresponding to the air outlet pipe. The air guide block is fixedly connected to the side of the corresponding air outlet pipe close to the exhaust port.

[0013] As a preferred technical solution of the present invention, it further includes a fixing frame corresponding to the exhaust port. The fixing frame is fixedly connected to the side of the refrigerated box close to the corresponding exhaust port. A baffle is rotatably connected to the side of the refrigerated box close to the corresponding exhaust port. The baffle is in contact and cooperation with the adjacent fixing frame to block the corresponding exhaust port.

[0014] The beneficial effects are as follows: The present invention refrigerates pea seeds by introducing cold air, uses the cold air to blow off the water droplets condensed on the surface of the pea seeds and their packaging bags, and condenses part of the moisture into water droplets through the cooling rack. A liquid discharge channel is formed by the diversion plate, the cooling rack, the liquid ports, the diversion cavities and the diversion channels therein, so that the condensed water is collected downward along the liquid discharge channel into the liquid storage tank. In this way, when refrigerating, the condensed water formed by the moisture in the box is prevented from adhering to the surface of the pea seeds and their packaging bags, effectively avoiding the seeds from absorbing moisture and mildewing or germinating.

[0015] By providing an exhaust port, the present invention enables the remaining moisture to be discharged together with the cold air. Additionally, through the inclined arrangement of the cooling rack, the condensed water flowing downward and the moisture flowing upward can be diverted and discharged according to their respective characteristics, effectively discharging the moisture and condensed water inside the refrigerator. Meanwhile, 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 their packaging bags.

[0016] While the carrier rack of the present invention intermittently swings back and forth to shake off water droplets, it also pulls a rotating plate on one side to change the wind direction, causing all the cold air to be concentrated and directed towards the downward-inclined side of the carrier rack, strengthening the wind force, thereby accelerating the dropping of water droplets on the surface of the pea seeds and their packaging bags and enhancing the dehumidification effect.

[0017] When the cold air blower stops working, the torsion spring is used for resetting to close the opening and closing plate, preventing the water in the liquid storage tank from evaporating into moisture and flowing back into the refrigerator when the cold air blower is not working and the external temperature rises.

[0018] The present invention uses a fixing rack and a baffle to block the exhaust port, preventing the cold air inside from being discharged and affecting the refrigeration effect when the cold air blower is not working, while also preventing external moisture from entering. When the cold air and moisture are discharged, the baffle is blown open to open the exhaust port, and a part of the cold air is directed towards the exhaust port through a wind guiding block to accelerate the discharge of moisture.

It should be noted that: The words indicating directions such as up, down, left, and right in this article are only for the positions of the shown structures in the corresponding drawings. The serial numbers assigned to the components in this article itself, such as the first, second, etc., are only used to distinguish the described objects and do not have any sequential or technical meanings. And as used in this application, terms such as connection and coupling, unless otherwise specified, all include direct and indirect connection (coupling).

[0036] Embodiment 1: A low-temperature storage device for pea seeds, as Figures 1-6As shown in the figure, it includes a refrigerator box 101. A box door 102 is rotatably connected to the front side of the refrigerator box 101. A cooling rack 103 is fixedly connected inside the refrigerator box 101. The cooling rack 103 is provided with a plurality of inclined planes that are inclined towards the lower left. A cold air blower 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 cold air blower 104 is communicated with the top end of the air duct 105. The cooling rack 103 is provided with two carrier racks 106. Put the pea seeds into a packaging bag that can prevent moisture and allow moderate ventilation, and then place the packaging bag on the carrier rack 106. Three flow guiding plates 107 arranged in a stepped manner are fixedly connected to the bottom left side of each inclined plane of the cooling rack 103. The coolant flows along the inclined plane of the cooling rack 103 towards the lower left and reaches the flow guiding plate 107. Three air outlet pipes 108 are fixedly connected to one side of the cooling rack 103 close to each carrier rack 106. The air outlet pipes 108 are located below the adjacent carrier racks 106. Three longitudinally distributed flow guiding cavities 109 are opened on the left side of the cooling rack 103. The flow guiding cavities 109 are inclined towards the front lower part. The flow guiding plate 107 is used to guide the coolant to the adjacent flow guiding cavity 109 to the left. A liquid storage tank 110 is arranged at the inner bottom of the refrigerator box 101. A flow guiding channel 111 is opened at the front part of the left side of the cooling rack 103. Both the flow guiding cavity 109 and the liquid storage tank 110 are communicated with the flow guiding channel 111. An air vent 112 corresponding to the air outlet pipe 108 is opened on the left side of the cooling rack 103. The air outlet pipe 108 is communicated with the adjacent air duct 105 through the air vent 112. A liquid port 113 is opened on one side of the cooling rack 103 close to the adjacent air outlet pipes 108. The liquid port 113 is communicated with the adjacent flow guiding cavity 109. The coolant on the flow guiding plate 107 is discharged into the flow guiding cavity 109 through the liquid port 113. Three longitudinally distributed exhaust ports 114 are opened on the right side of the refrigerator box 101. The cold air and moisture are discharged through the exhaust ports 114.

[0037] First, put the pea seeds into a packaging bag that can both prevent moisture and allow moderate ventilation. Then, open the box door 102, place the packaging bag on the carrier 106, and then close the box door 102. Start the cold air blower 104. The dry and cold air flow flows downward along the air duct 105, and then enters the air outlet duct 108 through each ventilation port 112. The cold air in the air outlet duct 108 blows upward, blowing off the water droplets on the surface of the pea seeds and their packaging bags. The blown-off water droplets fall on the inclined surface of the cooling rack 103 near the air outlet duct 108, and then flow left and downward to the liquid port 113 and enter the diversion cavity 109. At the same time, the cold air carries the moisture diffused in the box and floats 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 duct 108, and flows left and downward along the cooling rack 103 to the diversion plate 107, and then flows left and downward along the diversion plate 107 into the diversion cavity 109. The cooling liquid flowing into the diversion cavity 109 flows forward and downward into the diversion channel 111, and finally flows downward along the diversion channel 111 into the liquid storage tank 110. The remaining moisture is discharged out of the box through the exhaust port 114 together with the cold air.

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

[0039] The present invention is provided with an exhaust port 114, so that the remaining moisture is discharged together with the cold air, and through the inclined setting of the cooling rack 103, the condensed water flowing to the lower part and the moisture flowing to the higher part can be diverted and discharged according to their own characteristics, achieving the effect of effectively discharging the moisture and condensed water in the refrigerating box 101. At the same time, the structural design of the cooling rack 103 can prevent the condensed water from flowing back and falling on the surface of the pea seeds and their packaging bags.

[0040] Such as Figures 7-9As shown in the figure, it further includes four telescopic frames 201. The bearing frame 106 is rotatably connected to the cooling frame 103. Every two telescopic frames 201 are respectively distributed on the left and right sides at the rear of a bearing frame 106. The telescopic frame 201 is rotatably connected to the adjacent bearing frame 106. There is a rotating frame 202 rotatably connected between the lower part of the telescopic frame 201 and the cooling frame 103. There is a spring 203 fixedly connected between the rotating frame 202 and the cooling frame 103. There are twelve rotating plates 204 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 plate 204. There are connecting rods 205 symmetrically distributed along the front and rear of the rotating plate 204 rotatably connected between the six rotating plates 204 on the adjacent left side and the six rotating plates 204 on the adjacent right side.

[0041] As Figure 10 shown in the figure, it further includes a rotating frame 301 corresponding to the bearing frame 106. The rotating frame 301 is fixedly connected to the middle part at the rear of the corresponding bearing frame 106. There is a cylinder 302 corresponding to the rotating frame 301 fixedly connected to the rear outer wall of the refrigerating box 101. The telescopic rod of the cylinder 302 is rotatably connected to the corresponding rotating frame 301.

[0042] In order to accelerate the dropping of the water droplets on the surface of the pea seeds and their packaging bags, control the intermittent telescopic movement of the telescopic rod of the cylinder 302. The telescopic rod of the cylinder 302 drives the bearing frame 106 to swing back and forth intermittently clockwise and counterclockwise through the rotating frame 301, so as to shake off the water droplets on the surface of the pea seeds and their packaging bags.

[0043] When the bearing frame 106 is horizontally placed, the rotating plates 204 on the left and right sides are both vertically upward, and the telescopic frames 201 are all stretched to the maximum extent. When the bearing frame 106 swings clockwise, only the right side of the bearing frame 106 compresses the right telescopic frame 201 and drives the right telescopic frame 201 to rotate alone. The left side of the bearing frame 106 drives the left rotating frame 202 to rotate by pulling the left telescopic frame 201. The spring 203 deforms. The left rotating frame 202 cooperates with the left connecting rod 205 to drive the left rotating plate 204 to swing clockwise, so as to direct the cold air on the left upward to the bearing frame 106 inclined downward to the right. In this way, all the cold air is concentrated and directed to the right, strengthening the wind force so that the water droplets on the right are more likely to drop. Similarly, when the bearing frame 106 swings counterclockwise, it will direct the cold air on the right upward to the bearing frame 106 inclined downward to the left. In this way, all the cold air is concentrated and directed to the left, strengthening the wind force so that the water droplets on the left are more likely to drop.

[0044] In summary, while the bearing frame 106 of the present invention swings back and forth intermittently to shake off the 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 where the bearing frame 106 is inclined downward, strengthening the wind force, thereby accelerating the dropping of the water droplets on the surface of the pea seeds and their packaging bags and enhancing the dehumidification effect.

[0045] As Figure 11 and Figure 13 shown, it further includes an opening and closing frame 401. The opening and closing frame 401 is rotatably connected to the upper part between the air guide pipes 105. A torsion spring 402 is fixedly connected between the opening and closing frame 401 and the rear air guide pipe 105. A push-pull rod 403 is rotatably connected to the front side of the opening and closing frame 401. A sliding frame 404 is slidably connected in the vertical direction on the side of the cooling frame 103 close to the liquid storage tank 110. The upper side of the sliding frame 404 is rotatably connected to the push-pull rod 403. An opening and closing plate 405 is rotatably connected to the front side of the liquid storage tank 110. When the opening and closing plate 405 is rotated and opened, the liquid storage tank 110 is communicated with the diversion channel 111. An activity groove is formed 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 activity groove.

[0046] When the cold air blower 104 is working, when the cold air enters the air guide pipe 105, it will blow the opening and closing frame 401 downward, the torsion spring 402 deforms, 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 activity groove, so that the condensate can flow into the liquid storage tank 110. When the cold air blower 104 stops working, the torsion spring 402 resets, 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 activity groove, preventing the water in the liquid storage tank 110 from evaporating into moisture and flowing back into the refrigerating box 101 when the cold air blower 104 is not working and the external temperature rises.

[0047] As Figures 14-15 shown, it further 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 direct the gas to the exhaust port 114 to accelerate the discharge of moisture. A fixing frame 502 corresponding to the exhaust port 114 is fixedly connected to the right side of the refrigerating box 101. A baffle 503 is rotatably connected to the side of the refrigerating box 101 close to the corresponding exhaust port 114. The baffle 503 is located above the adjacent fixing frame 502, and the baffle 503 is in contact and cooperation with the adjacent fixing frame 502 to block the corresponding exhaust port 114.

[0048] In the present invention, part of the cold air is directed to the exhaust port 114 through the air guide block 501 to accelerate the discharge of moisture, and when the cold air and moisture are discharged, the baffle 503 is blown upward, so that the baffle 503 is separated from the fixing frame 502, thus not blocking the exhaust port 114. When the cold air blower 104 stops working, the rotating plate 204 swings downward under the action of gravity to contact the fixing frame 502, thus blocking the exhaust port 114. In this way, when the cold air blower 104 is not working, the cold air inside is prevented from being discharged, which affects the refrigeration effect, and at the same time, the external moisture is prevented from entering.

Accordingly, the scope of the present disclosure should not be limited to the above-described embodiments, but should be determined not only by the appended claims but also by the equivalents of the appended claims.
