Description

Technical Field

[0001] This invention relates to the field of grain storage technology, specifically to an intelligent humidity-controlled and insect-proof grain storage device. Background Technology

[0002] With social development and population growth, the demand for food is increasing year by year, and food security has become a global focus. Food is not only the foundation of human survival, but also the cornerstone of national economic development and social stability. Therefore, the storage and management of food is particularly critical, as it is directly related to the quality and safety of food, storage capacity, and emergency supply.

[0003] However, during grain storage, grains are often affected by humidity, which can cause them to mold or produce insect eggs, leading to spoilage. The current solution is usually to store them in airtight containers, but this prevents the grains from ventilating, and they will spoil over time. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an intelligent humidity-controlled and insect-proof grain storage device, which solves the problem that grains are often affected by humidity during traditional storage, leading to mold growth or the formation of insect eggs and thus grain spoilage.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: an intelligent humidity-controlled and insect-proof grain storage device, comprising a storage box, wherein several ventilation slots are equally spaced on both sides of the storage box, the storage box is divided into two areas: a drying equipment area and a storage area, wherein a storage mesh bin for storing grain is provided in the storage area, and the upper part of the storage mesh bin extends to the top of the storage box.

[0006] The ventilation duct has grooves on both the upper and lower sides. A movable plate is hinged to one side of the groove. Drying cotton is placed on the opposite side of the two movable plates, and small holes are densely distributed on the movable plates. The bottom of the movable plate away from its hinge point is connected to the bottom of the groove by a water-swellable rubber block. When the water-swellable rubber block is dry, the two movable plates are open, allowing the ventilation duct to ventilate the grain normally. When the water-swellable rubber block becomes damp, deforms, and expands, it causes the two movable plates to close together on one side, sealing the ventilation duct and stopping the ventilation of the grain.

[0007] Preferably, a hot air blower is installed in the drying equipment area. The air outlet of the hot air blower is connected to an air supply hood. The upper side of the air supply hood is connected to the top of the drying equipment area. The top of the drying equipment area is located inside the air supply hood and has several air supply channels arranged in a ring. The air supply channels are located around the storage bin and are used to send hot air from the hot air blower into the storage area. The intelligent humidity-controlled and insect-proof grain storage device also includes a power control mechanism. By displacing the two movable plates in the ventilation slot at the bottom of the storage box, the power control mechanism is activated and the power to the hot air blower is automatically turned on. The hot air blower dries the grain in the storage bin.

[0008] Preferably, the power control mechanism includes a limiting rod connected to the inner side of the drying equipment area. A moving strip is laterally slidably sleeved on the outside of the limiting rod. A damping rod is connected to one side of the lower end of the moving strip. One end of the damping rod is connected to a first conductive plate. The power control mechanism also includes a second conductive plate disposed on the inner side of the drying equipment area, corresponding to the first conductive plate. A first spring is also sleeved on the outside of the limiting rod. The two ends of the first spring are respectively connected to the inner side of the drying equipment area and one side of the moving strip. A traction rope is also connected to one side of the moving strip. The other end of the traction rope slides through the bottom of the lowest ventilation slot on the inner side of the drying equipment area and the storage box side, and is connected to the bottom of the lowest movable plate inside it. By rotating the movable plate, the traction rope pulls the moving strip to slide on the limiting rod, so that the first conductive plate contacts the second conductive plate, and the power supply of the hot air blower is turned on.

[0009] Preferably, when the first spring is in the reset state, the first conductive sheet and the second conductive sheet are close to each other but not in contact.

[0010] Preferably, the power control mechanism further includes a guide wheel disposed on one side of the outside of the storage box, the guide wheel guiding the traction rope.

[0011] Preferably, the intelligent humidity-controlled and insect-proof grain storage device also includes a cleaning mechanism. A worm gear fan is installed on the top side inside the drying equipment area. The worm gear fan is rotated by the high-speed airflow generated by the hot air blower. The worm gear fan drives the cleaning mechanism to clean the insect eggs attached to the outside of the storage mesh.

[0012] Preferably, the cleaning mechanism includes a drive unit and an execution unit. The bottom of the storage mesh bin is provided with an opening groove that does not penetrate its interior. The drive unit includes a main gear and a driven gear rotatably disposed in the opening groove at the bottom of the storage mesh bin, and the main gear and the driven gear mesh with each other. The upper end of the worm gear fan is connected to the main gear. The execution unit includes an annular sleeve rotatably disposed at the lowest point outside the storage mesh bin. A protrusion is provided on one side of the annular sleeve, and a limiting tube is connected to the upper part of the protrusion. A cleaning brush for cleaning insect eggs attached to the outside of the storage mesh bin is provided on one side of the limiting tube. A slot corresponding to the driven gear is provided on one side of the opening groove at the bottom of the storage mesh bin. An annular groove is provided on the inner side of the annular sleeve, and an internal rack is provided in the annular groove. The driven gear meshes with the internal rack inside the annular sleeve through the slot.

[0013] Preferably, the limiting tube contains an insecticide, and the side of the limiting tube away from the cleaning brush is densely covered with odor dissipation holes.

[0014] Preferably, the intelligent humidity-controlled and insect-proof grain storage device further includes a pressure relief mechanism disposed on the top of the storage box. The pressure relief mechanism includes a pressure relief cylinder communicating with the inside of the storage box. A second spring is connected to the top side of the inside of the pressure relief cylinder. A movable plug is connected to the lower end of the second spring. A pressure relief groove is disposed on the outside of the pressure relief cylinder. When the second spring is in the reset state, the movable plug seals the pressure relief groove.

[0015] This invention provides an intelligent humidity-controlled and insect-proof grain storage device, which has the following advantages compared with the prior art:

[0016] 1. This intelligent humidity-controlled and insect-proof grain storage device utilizes the property of water-swellable rubber blocks. When the grain storage environment is humid, the water-swellable rubber blocks will expand, causing the two movable plates inside the ventilation slot to close together, preventing humid air from entering the storage box. When the water-swellable rubber blocks dry, they will return to their original shape, allowing the two movable plates to open and the ventilation slot to ventilate the grain, preventing it from spoiling.

[0017] 2. This intelligent humidity-controlled and insect-proof grain storage device, when the two movable plates in the bottom ventilation slot of the storage box are combined, will pull the traction rope, causing the two conductive plates to contact and connect the power supply of the hot air blower. The hot air blows out hot air to dry the grain and prevent the grain from becoming too damp. When the two movable plates are separated, the two conductive plates no longer contact each other, and the blowing and drying operation of the grain stops.

[0018] 3. When the hot air blower is working, the turbine fan can rotate, thereby driving the cleaning mechanism to work. The cleaning brush removes the insect eggs attached to the outside of the storage mesh, which protects the grain. The insecticide in the limiting tube further eliminates insects, making the grain less prone to mold. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-10 This invention provides four technical solutions:

[0032] Example 1

[0033] Please see Figures 1-2 In this embodiment of the invention, an intelligent humidity-controlled and insect-proof grain storage device includes a storage box 1. Several ventilation slots 2 are equidistantly arranged on both sides of the storage box 1. The storage box 1 is divided into two areas: a drying equipment area 3 and a storage area 4. The storage area 4 is provided with a storage mesh 5 for storing grain. The upper part of the storage mesh 5 extends to the top of the storage box 1.

[0034] Please see Figures 2-5 In this embodiment of the invention, the ventilation duct 2 has grooves 21 on both the upper and lower sides. A movable plate 22 is hinged to one side of the groove 21. Drying cotton 23 is provided on the opposite side of the two movable plates 22. Small holes 24 are densely distributed on the movable plates 22. The bottom side of the movable plate 22 away from its hinge point is connected to the bottom of the groove 21 by a water-swellable rubber block 25. When the water-swellable rubber block 25 is in a dry state, the two movable plates 22 are in an open state, allowing the ventilation duct 2 to ventilate the grain normally. When the water-swellable rubber block 25 becomes damp, deforms, and expands, it causes the two movable plates 22 to close together on one side, sealing the ventilation duct 2 and stopping the ventilation operation for the grain.

[0035] In the above scheme: when the grain storage environment is dry, the water-swellable rubber block 25 will be in a dry state and will not deform or expand. At this time, the ventilation slot 2 will normally ventilate the grain. When the storage environment is too humid, moisture enters the ventilation slot 2. The drying cotton 23 on the movable plate 22 first absorbs the moisture, and the excess moisture enters through the small holes 24 on the movable plate 22 and wets the water-swellable rubber block 25. The water-swellable rubber block 25 will expand after getting wet, thereby pushing the movable plate 22 to rotate, so that one side of the two movable plates 22 contacts each other and seals the ventilation slot 2. At this time, external moisture cannot enter the storage box 1.

[0036] Example 2 differs from Example 1 in that:

[0037] Please see Figure 2 and Figure 6In this embodiment of the invention, a hot air blower 7 is installed in the drying equipment area 3. The air outlet of the hot air blower 7 is connected to an air supply hood 8. The upper side of the air supply hood 8 is connected to the top of the drying equipment area 3. The top of the drying equipment area 3 is located inside the air supply hood 8 and has several air supply channels 10 arranged in a ring. The air supply channels 10 are located around the storage mesh 5 and are used to send the hot air from the hot air blower 7 into the storage area 4. The intelligent humidity-controlled and insect-proof grain storage device also includes a power control mechanism 6. By the displacement of the two movable plates 22 in the ventilation slot 2 at the bottom of the storage box 1, the power control mechanism 6 is activated and the power supply of the hot air blower 7 is automatically turned on. The hot air blower 7 blows air to dry the grain in the storage mesh 5.

[0038] Please see Figure 6 and Figure 7 In this embodiment of the invention, the power control mechanism 6 includes a limiting rod 62 connected to the inner side of the drying equipment area 3. A moving strip 63 is laterally slidably sleeved on the outside of the limiting rod 62. A damping rod 65 is connected to one side of the lower end of the moving strip 63. One end of the damping rod 65 is connected to a first conductive sheet 66. The power control mechanism 6 also includes a second conductive sheet 67 disposed on the inner side of the drying equipment area 3, corresponding to the first conductive sheet 66. A first spring 68 is also sleeved on the outside of the limiting rod 62. The two ends of the first spring 68 are respectively connected to the inner side of the drying equipment area 3 and one side of the moving strip 63. A traction rope 64 is also connected to one side of the moving strip 63. The other end of the traction rope 64 slides through the bottom of the lowest ventilation slot 2 on the inner side of the drying equipment area 3 and the side of the storage box 1 and is connected to the bottom of the lowest movable plate 22 inside it. By rotating the movable plate 22, the traction rope 64 pulls the moving strip 63 to slide on the limiting rod 62, so that the first conductive sheet 66 contacts the second conductive sheet 67, and the power supply of the hot air blower 7 is turned on.

[0039] In the above scheme: when the two movable plates 22 in the lowest ventilation slot 2 on the storage box 1 come into contact, as the movable plates 22 rotate, they will pull the traction rope 64 to move. Under the elasticity of the first spring 68, the traction rope 64 pulls the moving bar 63 to slide on the limit rod 62. The moving bar 63 drives the damping rod 65 to move, so that the first conductive piece 66 at one end of the damping rod 65 abuts against the second conductive piece 67, thereby connecting the power supply of the hot air blower 7. The hot air blows out hot air, which enters through the air delivery slot 10. The grain is placed in storage area 4 and dried by blowing air into the storage mesh 5. As the hot air blower 7 works continuously, the hot air gradually dries the water-swellable rubber block 25. After drying, the water-swellable rubber block 25 will return to its original shape, thereby opening the space between the two movable plates 22 and allowing the ventilation slot 2 to ventilate the grain normally. At this time, the first spring 68 will return to its original position, thereby causing the first conductive plate 66 to separate from the second conductive plate 67 and the two to no longer contact each other. This means that the power supply of the hot air blower 7 is turned off, and the blowing and drying operation of the grain is stopped.

[0040] For further details, please refer to Figure 6 and Figure 7 In this embodiment of the invention, when the first spring 68 is in the reset state, the first conductive sheet 66 and the second conductive sheet 67 are close but not in contact. When the movable plate 22 pulls the traction rope 64, the two conductive sheets will immediately come into contact, turning on the power of the hot air blower 7. Through the damping rod 65, after the two conductive sheets come into contact, the first conductive sheet 66 will continue to move towards the second conductive sheet 67. Under the elastic action of the damping rod 65, it will play a buffering role, so that the first conductive sheet 66 will not be damaged.

[0041] For further details, please refer to [link / reference]. Figure 6 and Figure 7 In this embodiment of the invention, the power control mechanism 6 further includes a guide wheel 61 disposed on one side of the outside of the storage box 1. The guide wheel 61 guides the traction rope 64 to prevent the traction rope 64 from getting stuck during movement.

[0042] Example 3 differs from Example 1 in that:

[0043] Please see Figure 6 In this embodiment of the invention, the intelligent humidity-controlled and insect-proof grain storage device also includes a cleaning mechanism 11. A worm gear fan 9 is installed on the top side inside the drying equipment area 3. The worm gear fan 9 is rotated by the high-speed airflow generated by the hot air blower 7. The worm gear fan 9 drives the cleaning mechanism 11 to clean the insect eggs attached to the outside of the storage mesh 5.

[0044] Please see Figure 6 and Figures 8-9 In this embodiment of the invention, the cleaning mechanism 11 includes a driving unit and an execution unit. The bottom of the storage mesh compartment 5 is provided with an opening groove that does not penetrate its interior. The driving unit includes a main gear 117 and a driven gear 118 rotatably disposed in the opening groove at the bottom of the storage mesh compartment 5. The main gear 117 and the driven gear 118 mesh with each other. The upper end of the worm gear fan 9 is connected to the main gear 117. The execution unit includes an annular sleeve 111 rotatably disposed at the lowest point outside the storage mesh compartment 5. One side of the annular sleeve 111... A protrusion 112 is provided, and a limiting tube 113 is connected to the upper part of the protrusion 112. A cleaning brush 114 for cleaning insect eggs attached to the outside of the storage net bin 5 is provided on one side of the limiting tube 113. A slot 119 corresponding to the driven gear 118 is provided on one side of the bottom opening slot of the storage net bin 5. An annular groove is provided on the inner side of the annular sleeve 111. An internal rack 116 is provided in the annular groove. The driven gear 118 meshes with the internal rack 116 inside the annular sleeve 111 through the slot 119.

[0045] In the above scheme: when the hot air blower 7 blows air, the high-speed airflow causes the worm gear fan 9 to rotate. The worm gear fan 9 drives the main gear 117 to rotate, and the main gear 117 drives the driven gear 118 that meshes with it to rotate. Since the driven gear 118 meshes with the internal rack 116 in the annular sleeve 111, the rotation of the driven gear 118 will drive the annular sleeve 111 to rotate on the storage mesh bin 5, causing the limiting tube 113 to rotate around the storage mesh bin 5. The cleaning brush 114 on the limiting tube 113 cleans off the insect eggs attached to the outer wall of the storage mesh bin 5.

[0046] For further details, please refer to Figure 6 and Figures 8-9 In this embodiment of the invention, the limiting tube 113 is provided with insecticide, and the side of the limiting tube 113 away from the cleaning brush 114 is densely provided with odor dispersing holes 115. The odor of the insecticide in the limiting tube 113 is emitted from the odor dispersing holes 115 to prevent the grain from becoming infested with insects.

[0047] Example 4 differs from Example 1 in that:

[0048] Please see Figure 10 In this embodiment of the invention, the intelligent humidity-controlled and insect-proof grain storage device further includes a pressure relief mechanism 12 disposed on the top of the storage box 1. The pressure relief mechanism 12 includes a pressure relief cylinder 121 communicating with the inside of the storage box 1. A second spring 123 is connected to the top side of the inside of the pressure relief cylinder 121. A movable plug 124 is connected to the lower end of the second spring 123. A pressure relief groove 122 is disposed on the outside of the pressure relief cylinder 121. When the second spring 123 is in the reset state, the movable plug 124 seals the pressure relief groove 122.

[0049] In the above scheme: as the hot air blower 7 works continuously, the pressure in the storage area 4 gradually increases. The pressure will exert pressure on the movable plug 124 in the pressure discharge cylinder 121. Under the elasticity of the second spring 123, the movable plug 124 moves up and exposes the pressure discharge groove 122 on the pressure discharge cylinder 121, thereby realizing the pressure discharge operation.

[0050] Working principle: When the grain storage environment is dry, the water-swellable rubber block 25 will be in a dry state and will not deform or expand. At this time, the ventilation slot 2 will ventilate the grain normally. When the storage environment is too humid, moisture enters the ventilation slot 2. The drying cotton 23 on the movable plate 22 first absorbs the moisture, and the excess moisture enters through the small holes 24 on the movable plate 22 and wets the water-swellable rubber block 25. The water-swellable rubber block 25 will expand after getting wet, thereby pushing the movable plate 22 to rotate, so that one side of the two movable plates 22 contacts each other and seals the ventilation slot 2. At this time, external moisture cannot enter the storage box 1.

[0051] When the two movable plates 22 in the bottom ventilation slot 2 of the storage box 1 come into contact, as the movable plates 22 rotate, they will pull the traction rope 64 to move. Under the elasticity of the first spring 68, the traction rope 64 pulls the moving bar 63 to slide on the limit rod 62. The moving bar 63 drives the damping rod 65 to move, so that the first conductive piece 66 at one end of the damping rod 65 abuts against the second conductive piece 67, thereby connecting the power supply of the hot air blower 7. The hot air blows out hot air, which enters the storage area 4 through the air delivery slot 10 to blow and dry the grain in the storage net hopper 5. As the hot air blower 7 works continuously, the hot air gradually dries the water-swellable rubber block 25. After the water-swellable rubber block 25 dries, it will return to its original shape, thereby opening the gap between the two movable plates 22 and allowing the ventilation slot 2 to ventilate the grain normally. At this time, the first spring 68 will reset, so that the first conductive piece 66 leaves the second conductive piece 67 and the two no longer come into contact, that is, the power supply of the hot air blower 7 is turned off, and the blowing and drying operation of the grain is stopped.

[0052] As the hot air blower 7 continues to work, the pressure in the storage area 4 gradually increases. The pressure will exert pressure on the movable plug 124 in the pressure discharge cylinder 121. Under the elasticity of the second spring 123, the movable plug 124 will move upward, and the pressure discharge groove 122 on the pressure discharge cylinder 121 will be exposed, thus realizing the pressure discharge operation.

[0053] When the hot air blower 7 blows air, the high-speed airflow causes the worm gear fan 9 to rotate. The worm gear fan 9 drives the main gear 117 to rotate, and the main gear 117 drives the driven gear 118 that meshes with it to rotate. Since the driven gear 118 meshes with the internal rack 116 in the annular sleeve 111, the rotation of the driven gear 118 will drive the annular sleeve 111 to rotate on the storage mesh bin 5, causing the limiting tube 113 to rotate around the storage mesh bin 5. The cleaning brush 114 on the limiting tube 113 cleans off the insect eggs attached to the outer wall of the storage mesh bin 5, and the odor of the insecticide in the limiting tube 113 is emitted from the odor vent 115 to prevent the grain from becoming infested with insects.
