Description

Technical Field

[0001] The present invention relates to the field of sweet potato storage, and particularly to a sweet potato storage device with ventilation and dehumidification functions and a usage method thereof. Background Art

[0002] After the harvest of sweet potatoes, a large number of sweet potatoes cannot be sold in time. At this time, these sweet potatoes need to be properly stored to keep them fresh for a long time and prevent them from spoiling too quickly. Since sweet potatoes have a lot of moisture and are difficult to store, if not carefully handled, they will prematurely deteriorate and rot. Therefore, the storage conditions and environment for sweet potatoes are relatively strict, with certain requirements for both temperature and humidity.

[0003] In the initial stage of sweet potato storage, since the internal activities of sweet potato tubers are still relatively active, they will release carbon dioxide and emit a certain amount of heat. Therefore, during the storage of sweet potatoes, a certain amount of ventilation should be maintained to allow the heat to dissipate. Otherwise, too high a temperature will cause the sweet potatoes to germinate and become hollow. In addition, a certain humidity also needs to be maintained during sweet potato storage. Too low humidity is likely to cause the sweet potatoes to dehydrate and wilt, reducing the quality of the sweet potatoes. However, once the humidity exceeds the standard, it is easy to cause the sweet potatoes to rot.

[0004] Publication No. CN105165293A discloses a sweet potato storage box, which includes a box body and a box cover connected to the box body. A suspended rack is provided inside the box body, which divides the box body into an upper box body and a lower box body. Ventilation openings are provided around the lower box body; a metal screen is provided on the suspended rack. By placing the sweet potatoes on the suspended rack with the metal screen and providing ventilation openings around the lower box body, the temperature and humidity inside the storage box can be well maintained, enabling the sweet potatoes to be stored for a long time. The above sweet potato storage box ventilates through the ventilation openings. However, the sweet potatoes at the bottom of the storage box are pressed by the sweet potatoes above for a long time and cannot be well ventilated and dehumidified, resulting in the sweet potatoes at the bottom being easily rotted. In addition, only ventilating through the ventilation openings, the ventilation during the storage of sweet potatoes is not well done, easily causing the sweet potatoes to germinate and become hollow. Summary of the Invention

[0005] The purpose of the present invention is to provide a sweet potato storage device with ventilation and dehumidification functions and a usage method thereof, which overcomes the above technical deficiencies. The present invention has the function of being able to ventilate and dehumidify more fully and comprehensively during the process of storing sweet potatoes, making the storage effect of sweet potatoes better.

[0012] As a preferred technical solution of the present invention, it further includes convex rollers. Four convex rollers are rotatably connected to each concave plate.

[0013] As a preferred technical solution of the present invention, it further includes a ventilation mechanism. A ventilation mechanism is provided between the support plate and the sweet potato basket. The ventilation mechanism includes a top plate, a ventilation pipe and an air bag. Two top plates are fixedly connected to the bottom of each sweet potato basket. Two ventilation pipes are communicated with the bottom of each sweet potato basket. Each top plate and ventilation pipe pass through the adjacent supporting basket. Two air bags are fixedly connected to each support plate. The other end of each top plate is fixedly connected to the adjacent air bag. The other end of each ventilation pipe is communicated with the adjacent air bag.

[0014] As a preferred technical solution of the present invention, a usage method of a sweet potato storage device with ventilation and dehumidification functions further includes the following working steps:

[0015] S1. First, open the warehouse door, put the sweet potatoes into the sweet potato baskets for storage, and then close the warehouse door. The discharge pipe performs natural ventilation on the storage bin.

[0016] S2. When it is necessary to dehumidify the sweet potatoes, start the electric push rod and the dehumidifier, so that the movable plug moves downward to open the hole of the storage bin, and let the dehumidifier dehumidify the inside of the storage bin. At the same time, the supporting basket swings towards the direction close to the discharge pipe, so that the sweet potato basket is closer to the discharge pipe.

[0017] S3. When the sweet potato basket swings, the support plate squeezes the pulley and the support column, and then pushes the sweet potato basket to move upward to ventilate the bottom of the sweet potatoes. At the same time, the top column squeezes the rubber plate to rotate, so that the spiral stirring blade rotates to slightly stir the sweet potatoes.

[0018] S4. When the dehumidification of the sweet potatoes is completed, turn off the electric push rod and the dehumidifier, and the movable plug moves upward to block the hole of the storage bin again.

[0019] The beneficial effects are as follows: 1. During the storage of sweet potatoes, the sweet potatoes can be ventilated and cooled through the ventilation holes on the sweet potato baskets and the supporting baskets. In addition, the dehumidifier can further ventilate and dehumidify the interior of the storage bin, avoiding excessive temperature and humidity inside the storage bin, and thus preventing the sweet potatoes from rotting or germinating.

[0020] 2. The telescopic rod of the electric push rod contracts or extends, driving the discharge pipe to move up and down, and then driving the concave plate to move up and down. The up and down movement of the concave plate drives the movable block to swing up and down, and then drives the supporting basket and the sweet potato basket to swing left and right, allowing air to better enter the gaps between the sweet potatoes, thereby making the ventilation and dehumidification more efficient and achieving a better ventilation and dehumidification effect.

[0021] 3. The present invention is provided with a pushing component and a ventilation component, enabling the sweet potato basket to be slightly pushed out during the swinging process, increasing the ventilation space for the sweet potatoes at the bottom of the sweet potato basket. At the same time, the swinging of the sweet potato basket causes the top plate to squeeze the airbag, and the gas in the airbag enters the sweet potato basket through the ventilation pipe, blowing out the air at the bottom of the sweet potato basket, which can achieve a better ventilation and dehumidification effect on the sweet potatoes at the bottom, thus preventing the sweet potatoes at the bottom from rotting or germinating due to accumulated heat and excessive humidity inside the sweet potatoes.

[0022] 4. When the sweet potato basket swings towards the direction close to the discharge pipe, the top column contacts the rubber plate. The top column squeezing the rubber plate drives the rubber plate, the rotating shaft, and the spiral stirring blade to rotate together. The torsion spring is twisted. When the top column no longer squeezes the rubber plate, the reset of the torsion spring drives the rotating shaft, the rubber plate, and the spiral stirring blade to rotate in the reverse direction and reset. The rotation of the spiral stirring blade gently stirs the sweet potatoes in the sweet potato basket, thereby making the ventilation and dehumidification effect inside the sweet potatoes better and further preventing the sweet potatoes from rotting or germinating due to accumulated heat.

Detailed implementation manners

[0034] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "connected" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0035] Embodiment 1: A sweet potato storage device with ventilation and dehumidification functions and its usage method, as Figures 1-9 shown, comprising a chassis 1, a storage bin 2, a warehouse door 3, a support plate 4, a movable plug 5, a dehumidification component and a swinging component. The storage bin 2 is connected to the chassis 1 by bolts. A plurality of holes are opened at the bottom of the storage bin 2. The warehouse door 3 is rotatably connected to the storage bin 2. Two support plates 4 are connected to the inner wall of the storage bin 2 by bolts. A movable plug 5 is plugged between the plurality of holes of the storage bin 2. The movable plug 5 is located below the storage bin 2. A dehumidification component is provided on the chassis 1, and a swinging component is provided on the dehumidification component.

[0036] The dehumidifying component includes an electric push rod 61, a discharge pipe 62, and a dehumidifier 63. The electric push rod 61 is bolted to the chassis 1. The discharge pipe 62 is bolted to the telescopic rod of the electric push rod 61. A number of air holes are formed in the discharge pipe 62. The discharge pipe 62 is slidably connected to the storage bin 2. The discharge pipe 62 is fixedly connected to the movable plug 5. The dehumidifier 63 is bolted to the chassis 1 and is used for dehumidifying sweet potatoes. The electric push rod 61 passes through the dehumidifier 63.

[0037] The swinging component includes a concave plate 71, a movable block 73, a supporting basket 74, and a sweet potato basket 75. Two concave plates 71 are bolted to the discharge pipe 62. Both of the two concave plates 71 are located inside the storage bin 2. Grooves are formed on both sides of each concave plate 71. Two through grooves 72 are formed in each supporting plate 4. Two movable blocks 73 are rotatably connected to each supporting plate 4. The movable blocks 73 pass through the adjacent through grooves 72. The lower end of each movable block 73 is located in the groove of the adjacent concave plate 71. The upper end of each movable block 73 is bolted to a supporting basket 74. A sweet potato basket 75 is placed in each supporting basket 74. The sweet potato basket 75 is used for placing sweet potatoes. A number of ventilation holes are formed in both the sweet potato basket 75 and the supporting basket 74.

[0038] Application method: At the beginning, the staff opens the warehouse door 3, puts the sweet potatoes into the sweet potato basket 75, and then closes the warehouse door 3 so that the sweet potatoes can be stored in the storage bin 2. The sweet potatoes can be ventilated and cooled through the ventilation holes in the sweet potato basket 75 and the supporting basket 74. When further ventilation and dehumidification of the sweet potatoes in the storage bin 2 are required, the staff starts the electric push rod 61 and the dehumidifier 63. The contraction of the telescopic rod of the electric push rod 61 will drive the discharge pipe 62 to move downward. The downward movement of the discharge pipe 62 will drive the movable plug 5 to move downward. The downward movement of the movable plug 5 will disengage from the hole at the bottom of the storage bin 2, enabling the dehumidifier 63 to further ventilate and dehumidify the interior of the storage bin 2, preventing the temperature and humidity inside the storage bin 2 from being too high, and thus preventing the sweet potatoes from rotting or germinating. The extension of the telescopic rod of the electric push rod 61 will drive the discharge pipe 62 to reset upward. The upward reset of the discharge pipe 62 will drive the movable plug 5 to reset upward and re-block the hole at the bottom of the storage bin 2.

[0039] When the discharge pipe 62 moves downward, it will drive the concave plate 71 to move downward. When the concave plate 71 moves downward, the movable block 73 will contact the upper side of the adjacent groove and be pushed to swing downward. When the movable block 73 swings downward, it will drive the basket 74 to swing towards the discharge pipe 62, and thus will also drive the sweet potato basket 75 to swing towards the discharge pipe 62. When the discharge pipe 62 resets upward, it will drive the concave plate 71 to reset upward. When the concave plate 71 no longer presses the movable block 73, the movable block 73, the basket 74 and the sweet potato basket 75 will reset away from the discharge pipe 62. When the concave plate 71 continues to move upward, the movable block 73 will contact the lower side of the adjacent groove and be pushed to swing upward. When the movable block 73 swings upward, it will drive the basket 74 to swing away from the discharge pipe 62, and thus will drive the sweet potato basket 75 to swing away from the discharge pipe 62, enabling the basket 74 and the sweet potato basket 75 to swing left and right, so that air can better enter the gaps between the sweet potatoes, thereby making the ventilation and dehumidification more efficient and achieving a better ventilation and dehumidification effect.

[0040] Embodiment 2: On the basis of Embodiment 1, as Figures 1-9 shown, it further includes a pushing component. A pushing component is provided between each basket 74 and the adjacent sweet potato basket 75. The pushing component includes a support column 81, a pulley 82, a guide rail 83 and a slider 84. Two support columns 81 are bolted to the bottom of each sweet potato basket 75. Each support column 81 passes through the adjacent basket 74. A pulley 82 is rotatably connected to the bottom of each support column 81. Each pulley 82 contacts the adjacent support plate 4. Two guide rails 83 are bolted to the inner wall of each basket 74. Two sliders 84 are bolted to the outer wall of each sweet potato basket 75. Each slider 84 is slidably connected to the adjacent guide rail 83.

[0041] The swing of the sweet potato basket 75 will drive the swing of the two support columns 81 connected thereto. Since pulleys 82 are provided at the bottoms of the support columns 81, one of the pulleys 82 will disengage from the support plate 4, and the other pulley 82 will slide on the support plate 4. At the same time, the support plate 4 will squeeze the pulley 82 and the support column 81 that are still in contact with it, thereby pushing the sweet potato basket 75 to move upward. The reset of the sweet potato basket 75 in the direction away from the discharge pipe 62 will drive the support column 81 and the pulley 82 to reset together, thereby driving the sweet potato basket 75 to reset downward. The swing of the sweet potato basket 75 in the direction away from the discharge pipe 62 will drive the support column 81 and the pulley 82 to swing together, thereby causing the support plate 4 to squeeze the pulley 82 and the support column 81 that are still in contact with it, thereby pushing the sweet potato basket 75 to move upward again, so as to achieve the purpose of slightly pushing out the sweet potato basket 75, increasing the ventilation space for the sweet potatoes at the bottom of the sweet potato basket 75, achieving a better ventilation and dehumidification effect on the sweet potatoes at the bottom, thereby avoiding the internal heat accumulation and excessive humidity of the sweet potatoes causing the sweet potatoes at the bottom to rot or germinate.

[0042] Embodiment 3: On the basis of Embodiment 2, as Figures 1-8 shown, it further includes a stirring member. Each sweet potato basket 75 is provided with a stirring member. The stirring member includes a fixing frame 91, a rotating shaft 92, a rubber plate 93, a torsion spring 94, a top column 95, and a spiral stirring blade 96. The top of each sweet potato basket 75 is bolted with a fixing frame 91. A rotating shaft 92 is rotatably connected to each fixing frame 91. The rotating shaft 92 is vertically arranged. A rubber plate 93 is bolted to each rotating shaft 92. A torsion spring 94 is connected between each rotating shaft 92 and the adjacent fixing frame 91 by a hook. The torsion spring 94 is used to drive the rotating shaft 92 to reset. A spiral stirring blade 96 is bolted to the lower end of each rotating shaft 92. The spiral stirring blade 96 is used to stir the sweet potatoes in the sweet potato basket 75. Each spiral stirring blade 96 is located in the adjacent sweet potato basket 75. Two top columns 95 are bolted to the discharge pipe 62. Each rubber plate 93 is in contact with the adjacent top column 95.

[0043] When the sweet potato basket 75 swings towards the discharge pipe 62, it will drive the fixed frame 91, the rotating shaft 92 and the rubber plate 93 to swing towards the discharge pipe 62 together. This will cause the rubber plate 93 to contact and be squeezed by the top column 95. The top column 95 will push the rubber plate 93 to rotate, and the torsion spring 94 will be twisted. The rotation of the rubber plate 93 will drive the rotation of the rotating shaft 92. The rotation of the rotating shaft 92 will drive the rotation of the spiral stirring blade 96. The rotation of the spiral stirring blade 96 will gently stir the sweet potatoes in the sweet potato basket 75. When the sweet potato basket 75 returns to its original position, the rubber plate 93 will no longer be squeezed by the top column 95. The reset of the torsion spring 94 will drive the reset of the rotating shaft 92. The reset of the rotating shaft 92 will drive the rubber plate 93 and the spiral stirring blade 96 to reset together, causing the spiral stirring blade 96 to gently stir the sweet potatoes in the sweet potato basket 75 again, thereby making the ventilation and dehumidification effect inside the sweet potatoes better and further preventing the sweet potatoes from accumulating heat and rotting or germinating.

[0044] Embodiment 4: On the basis of Embodiment 3, as Figures 2-9 shown, it further includes convex rollers 10. Four convex rollers 10 are rotatably connected to each concave plate 71. The convex rollers 10 are used to reduce the friction between the movable block 73 and the concave plate 71.

[0045] It further includes a ventilation mechanism. A ventilation mechanism is provided between the support plate 4 and the sweet potato basket 75. The ventilation mechanism includes a top plate 111, a ventilation pipe 112 and an airbag 113. Two top plates 111 are bolted to the bottom of each sweet potato basket 75. Two ventilation pipes 112 are communicated with the bottom of each sweet potato basket 75. Each top plate 111 and ventilation pipe 112 pass through the adjacent supporting basket 74. Two airbags 113 are bolted to each support plate 4. Each airbag 113 is located below the adjacent sweet potato basket 75. The other end of each top plate 111 is fixedly connected to the adjacent airbag 113. The other end of each ventilation pipe 112 is communicated with the adjacent airbag 113.

[0046] When the sweet potato basket 75 swings, it will cause the top plate 111 connected to it to squeeze the airbag 113. As a result, the gas in the airbag 113 will enter the sweet potato basket 75 through the ventilation pipe 112, blowing out the air at the bottom of the sweet potato basket 75, accelerating the air flow rate at the bottom of the sweet potato basket 75, and further achieving a better ventilation and dehumidification effect on the sweet potatoes at the bottom of the sweet potato basket 75, thereby preventing the sweet potatoes at the bottom from rotting or germinating due to poor ventilation and dehumidification effects.

[0047] After further ventilating and dehumidifying the sweet potatoes in the storage bin 2, the staff can turn off the dehumidifier 63 and the electric push rod 61. During the storage process of the sweet potatoes, the staff can repeat this process regularly to ensure that the sweet potatoes can obtain sufficient ventilation and dehumidification during storage, so as to prevent the sweet potatoes from rotting, germinating and becoming hollow.

[0048] The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to best explain the principles of the invention and its practical application, and to enable those of ordinary skill in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

When the sweet potato basket (75) swings, the support plate (4) squeezes the pulley (82) and the support column (81), thereby pushing the sweet potato basket (75) to move upward to ventilate the bottom of the sweet potatoes. At the same time, the top column (95) squeezes the rubber plate (93) to rotate, making the spiral stirring blade (96) made of rubber material rotate to slightly stir the sweet potatoes. S4. When the dehumidification of the sweet potatoes is completed, turn off the electric push rod (61) and the dehumidifier (63), and the movable plug (5) moves upward to block the hole of the storage bin (2) again.
