Description

Technical Field

[0001] This utility model relates to the technical field of bean sprout cultivation equipment, specifically a circulating ventilation cultivation box for clear water bean sprouts. Background Technology

[0002] As a common healthy vegetable, bean sprouts have strict requirements for environmental ventilation, water control and utilization of cultivation space during their cultivation process. In particular, water-grown bean sprouts, due to the water cultivation method, need to avoid the growth of mold caused by poor ventilation, while ensuring that the water supply is uniform and does not waste water resources. The spacing between cultivation layers should also be flexibly adjusted according to the growth stage of the bean sprouts to meet their growth needs.

[0003] In existing water-based bean sprout cultivation technology, the ventilation system is poorly designed, with most using fixed-position fans for ventilation. This makes it impossible to adjust the airflow position according to the different growth heights of the bean sprouts, resulting in uneven airflow distribution within the container and insufficient ventilation in some areas. This can easily lead to bean sprout rotting and quality degradation. Furthermore, the lack of an efficient water circulation and filtration mechanism means that the water used for spraying during the cultivation process is mostly used only once, which not only wastes water resources but also may cause unfiltered wastewater to be discharged directly, potentially carrying bean sprout residue, which does not meet environmental protection requirements. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a circulating ventilation cultivation box for water-grown bean sprouts, thereby solving the problems mentioned in the background art, such as uneven ventilation leading to easy rotting of bean sprouts and low water resource utilization in existing water-grown bean sprout cultivation technologies.

[0006] Preferably, the interior of the lifting plate is slidably connected to the outer wall of a pair of slide rails, the drain pipe extends through the interior of the filter box to the interior of the first mounting base, and the transport pipe extends through the interior of the filter box and the water pump and is connected to the water tank.

[0007] Preferably, a spacing adjustment unit is also provided on one side of the first mounting base and the second mounting base. The spacing adjustment unit includes a second fixing plate fixedly connected to one side of the first mounting base and the second mounting base. A second air pump is fixedly connected to the upper surface of the second fixing plate. A second air rod is fixedly connected to the output end of the upper surface of the second air pump. A pair of connecting blocks are fixedly connected to one side of the first mounting base. A pair of grooves are opened inside the pair of connecting blocks.

[0008] Preferably, the output end of the upper surface of the second air rod is connected to the lower surface of a second fixed plate, and the outer walls of a pair of connecting rods are slidably connected to the inside of the groove.

[0009] Preferably, a spray adjustment unit is also provided on one side of the second mounting base.

[0010] This invention provides a circulating ventilation incubator for bean sprouts grown in clear water. Compared with the prior art, it has the following advantages: With the setting of the blower unit, the first air pump drives the first air rod to move the lifting plate up and down along the slide rail. The vertical position of the blower can be adjusted according to the different growth heights of the bean sprouts. The servo motor drives the blower to rotate through the rotating shaft to adjust the blowing angle. Combined with the directional exhaust of the unidirectional exhaust fan and the air introduction of the air intake net, the airflow in the box is evenly distributed, avoiding the rotting of bean sprouts due to insufficient local ventilation. With the setting of the filter unit, the wastewater generated during the cultivation process flows into the filter box through the drain pipe. After passing through several filter screens to remove bean sprout residue and other impurities, the filtered clean water is then transported to the water tank for recycling by the water pump through the transport pipe. The diversion telescopic hose can be adapted to different spraying needs.

[0011] By adjusting the spacing unit, the second air pump drives the second air rod to extend and retract, causing the connecting rod on one side of the second mounting base to slide along the groove of the connecting block, thereby changing the spacing between the first and second mounting bases. This prevents the bean sprouts from being squeezed in the later stages of growth, ensuring the integrity of the bean sprout growth shape and increasing the cultivation yield per unit space. By adjusting the spray unit, the output end of the drive motor drives the threaded rod to rotate, causing the spray plate to move horizontally along the threaded rod. Furthermore, the water supply from the spray plate and the diverting telescopic hose can be adjusted according to the bean sprout growth density and regional needs, ensuring that the bean sprouts in each area of ​​the box receive a uniform water supply.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1:

[0015] Please see Figure 1 - Figure 3As shown, this embodiment proposes a circulating ventilation cultivation box for clear water bean sprouts, including: a box body 1, a unidirectional exhaust fan 2 fixedly connected to the upper surface of the box body 1, a pair of air inlet nets 3 opened on the left and right sides of the box body 1, a first mounting base 13 fixedly connected inside the box body 1, a second mounting base 19 provided on the upper surface of the first mounting base 13, a blowing unit and a filtering unit provided inside the box body 1, the blowing unit including a mounting bracket 4, a slide rail 5, a first fixing plate 6, a first air pump 7, a first air rod 8, a lifting plate 9, a servo motor 10, a rotating shaft 11 and a blower 12, a pair of mounting brackets 4 fixedly connected inside the box body 1, the pair of mounting brackets 4 A pair of slide rails 5 are fixedly connected to one side of the housing 1. A pair of first fixed plates 6 are fixedly connected to the left and right sides of the upper surface of the housing 1. A pair of first air pumps 7 are fixedly connected to the upper surface of the pair of first fixed plates 6. A pair of first air rods 8 are fixedly connected to the output end of the upper surface of the pair of first air pumps 7. A pair of lifting plates 9 are fixedly connected to the output end of the upper surface of the pair of first air rods 8. A pair of servo motors 10 are fixedly connected to one side of the pair of lifting plates 9. A pair of rotating shafts 11 are fixedly connected to the output end of one side of the pair of servo motors 10. A pair of blowers 12 are fixedly connected to the output end of one side of the pair of rotating shafts 11. The inside of the lifting plate 9 is slidably connected to the outer wall of the pair of slide rails 5. When the vertical height of the blower 12 needs to be adjusted to cover bean sprouts at different growth stages, the first air pump 7 is activated. The first air pump 7 drives the first air rod 8 at the output end to extend and retract. If the height of the bean sprouts increases, the first air rod 8 extends, causing the lifting plate 9 fixed thereto to slide upward along the outer wall of the slide rail 5. The servo motor 10 on one side of the lifting plate 9 is activated. The servo motor 10 drives a pair of rotating shafts 11 at the output end to rotate around their own axis. When the rotating shafts 11 rotate, they synchronously drive the blower 12 to rotate. The operation of the blower 12 generates airflow, which delivers fresh air to the cultivation area inside the box, providing sufficient oxygen for the growth of bean sprouts.

[0016] Preferred, such as Figure 2 As shown, the filtration unit includes a filter box 21, a drain pipe 22, a filter screen 23, a water pump 24, a transport pipe 25, a water tank 26, a water inlet pipe 27, and a diversion telescopic hose 28. The filter box 21 is fixedly connected to one side of the housing 1, and the drain pipe 22 is fixedly connected to one side of the filter box 21. Several filter screens 23 are fixedly connected inside the filter box 21. The water pump 24 is fixedly connected to the upper surface of the filter box 21. The transport pipe 25 is fixedly connected to the output end of one side of the water pump 24. The water tank 26 is fixedly connected to one side of the housing 1. The water inlet pipe 27 is fixedly connected to the upper surface of the water tank 26. Several diversion telescopic hoses 28 are fixedly connected to one side of the water tank 26. The drain pipe 22 extends through the interior of the filter box 21 to the interior of the first mounting base 13. The transport pipe 25 extends through the interior of the filter box 21 and the water pump 24 and is connected to the water tank 26. During the cultivation of bean sprouts in clear water, after the bean sprouts on the first mounting base 13 and the second mounting base 19 are sprayed, some of the clear water will seep into the interior of the first mounting base 13, forming wastewater containing bean sprout residue and impurities. Under the action of gravity, the wastewater flows naturally into the filter box 21 through the drain pipe 22 extending into the interior of the first mounting base 13. After entering the filter box 21, the wastewater passes through several filter screens 23 in sequence for multi-stage filtration, gradually removing impurities from the wastewater. When the filtered clear water in the filter box 21 reaches the preset water level, the water pump 24 is started: the water pump 24 generates suction to draw in the clear water that has undergone multi-stage purification in the filter box 21, and then transports it to the water tank 26 through the transport pipe 25. The clear water in the water tank 26 is transported to the spraying mechanism through several diversion telescopic hoses 28 on one side.

[0017] Preferred, such as Figure 2 As shown, a spacing adjustment unit is also provided on one side of the first mounting base 13 and the second mounting base 19. The spacing adjustment unit includes a second fixing plate 14, a second air pump 15, a second air rod 16, a connecting block 17, a groove 18, and a connecting rod 20. The second fixing plate 14 is fixedly connected to one side of the first mounting base 13 and the second mounting base 19. The second air pump 15 is fixedly connected to the upper surface of the second fixing plate 14. The output end of the upper surface of the second air pump 15 is fixedly connected to the second air rod 16. A pair of connecting blocks 17 are fixedly connected to one side of the first mounting base 13. A pair of grooves 18 are opened inside the pair of connecting blocks 17. A pair of connecting rods 20 are fixedly connected to one side of the second mounting base 19. The output end of the upper surface of the second air rod 16 is connected to the lower surface of a second fixing plate 14. The outer wall of the pair of connecting rods 20 is slidably connected to the inside of the groove 18. In the early stage of bean sprout growth, since the bean sprouts are relatively short, there is no need to adjust the spacing, and the spacing adjustment unit remains in its initial state. When the bean sprouts enter the middle stage of growth, the second air pump 15 operates to drive the second air rod 16 to extend slowly. The output end of the second air rod 16 is connected to the upper second fixed plate 14. When the second air rod 16 extends, it will push the upper second fixed plate 14 upward. The upper second fixed plate 14 is fixedly connected to the second mounting base 19, so it synchronously drives the second mounting base 19 to move upward. During the upward movement of the second mounting base 19, a pair of connecting rods 20 on one side slide upward along the groove 18 of the connecting block 17 on one side of the first mounting base 13.

[0018] Preferred, such as Figure 3As shown, a spray adjustment unit is also provided on one side of the second mounting base 19. The spray adjustment unit includes a connecting plate 29, a drive motor 30, a threaded rod 31, and a spray plate 32. Several connecting plates 29 are fixedly connected to the lower surface of the second mounting base 19. Several drive motors 30 are fixedly connected to one side of the several connecting plates 29. Several threaded rods 31 are fixedly connected to the output end of one side of the several drive motors 30. Spray plates 32 are threadedly connected to the outer wall of the several threaded rods 31. In the early stage of bean sprout growth, since the bean sprouts have not yet expanded significantly, there is no need to frequently adjust the spray position. When the bean sprouts enter the middle stage of growth, the drive motor 30 drives the threaded rod 31 to rotate clockwise. When the threaded rod 31 rotates, the spray plate 32 moves along the axis of the threaded rod 31 in the direction of bean sprout expansion. Then the spray system is started to test the water spray range and ensure that all bean sprouts can be sprayed evenly.

[0019] In use, before starting the clear water bean sprout cultivation, bean sprout seeds are evenly spread on the first mounting base 13. According to the initial distribution range of the seeds, the spray plate 32 is adjusted to the middle area directly above the first mounting base 13 by the drive motor 30 of the spray adjustment unit. The spray plate 32 is connected to the diversion telescopic hose 28 of the water tank 26. The second air pump 15 of the spacing adjustment unit controls the second air rod 16 to retract, so that the first mounting base 13 and the second mounting base 19 maintain the initial spacing. The connecting rod 20 fits against the bottom of the groove 18 of the connecting block 17. The first air pump 7 of the blowing unit controls the first air rod 8 to retract, so that the blower 12 is lowered to a height close to the initial spacing. The servo motor 10 adjusts the blower 12 to the initial angle of horizontal orientation towards the cultivation area. The blower 12 of the air blowing unit and the one-way exhaust fan 2 of the box 1 are activated. The blower 12 delivers fresh air to the cultivation area, and the one-way exhaust fan 2 directionally discharges carbon dioxide and moisture from the box. Fresh air from the outside enters the box 1 through the air intake net 3. The spray system is activated, and the clean water in the water tank 26 is delivered to the spray plate 32 through the diversion telescopic hose 28. The water is then evenly sprayed onto the seeds and seedlings through the spray holes. The wastewater that seeps into the first mounting base 13 after spraying flows into the filter box 21 through the drain pipe 22 under the action of gravity. After the multi-stage filter screen 23 removes small impurities, the water pump 24 is activated to transport the filtered clean water back to the water tank 26 through the transport pipe 25, realizing the recycling of water resources. The second air pump 15 of the spacing adjustment unit is started, which drives the second air rod 16 to slowly extend and push the second fixing plate 14 and the second mounting base 19 above to move upward. The connecting rod 20 on one side of the second mounting base 19 slides upward along the groove 18 of the connecting block 17 to ensure that the second mounting base 19 only rises vertically and does not tilt. After the spacing is adjusted, the second air pump 15 is turned off and the length of the second air rod 16 is locked to reserve space for the subsequent growth of bean sprouts.
