Abstract
Description
Technical Field
[0001] This utility model relates to a hydroponic vegetable cultivation device, specifically a hydroponic vegetable cultivation device, belonging to the technical field of hydroponic cultivation equipment. Background Technology
[0002] Hydroponics is a cultivation technique that uses nutrient solutions. Compared to soil cultivation, it is favored for its many advantages, such as accelerating crop growth, producing high-quality products, eliminating pollution, creating a clean and hygienic production environment, and reducing pests and diseases. At the same time, as people's health awareness gradually increases, hydroponic vegetable cultivation at home is becoming more and more widespread. Hydroponic devices make it convenient for people to use balconies, indoor spaces, and other spaces for hydroponic vegetable cultivation.
[0003] Chinese Patent No. CN218126116U discloses a water curtain-type vegetable cultivation component and an aquaponics hydroponic device, including a cultivation rack with at least one water storage layer and at least one cultivation layer arranged longitudinally below the water storage layer. Each water storage layer has an overflow drain that can form a water curtain. Each cultivation layer has a cultivation cavity, and the upper surface of the cultivation layer has at least one planting hole communicating with the cultivation cavity. The cultivation rack also has a water curtain channel distributed longitudinally. The cultivation cavity of each cultivation layer has an overflow outlet corresponding to the water curtain channel and is connected to the water curtain channel through the overflow outlet. The water curtain channel is connected to the water storage layer through the overflow drain. It can be used as a standalone hydroponic device for vegetable cultivation or placed in an aquaponics hydroponic device, making it more flexible and practical.
[0004] In existing technologies, the water level in the cultivation layer is uniform, which makes it difficult to adjust according to the water requirements of different vegetable roots. Shallow-rooted vegetables are prone to root rot due to lack of oxygen when the water level is too high, while deep-rooted vegetables are prone to insufficient nutrient absorption when the water level is too low. Multiple cultivation racks need to be prepared, which increases planting costs and cannot meet the needs of multi-variety planting. Utility Model Content

[0029] 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.
[0030] Example 1
[0031] like Figures 1 to 7 As shown, a hydroponic vegetable growing device includes a hollow cultivation rack 1, with multiple cultivation chambers 4 integrally formed on the outer wall of the cultivation rack 1, and a water level regulating mechanism 2 installed inside the cultivation rack 1.
[0032] The water level regulating mechanism 2 includes a planting trough 21 located inside the cultivation chamber 4 and connected to the inside of the cultivation rack 1. A guide plate 25 is fixedly connected to one side of the top of the planting trough 21 inside the cultivation rack 1. A baffle plate 23 is slidably connected to one side of the cultivation rack 1 near the planting trough 21. A fixed inner cylinder 29 is fixedly connected to the bottom of the cultivation rack 1. A connecting sleeve 24 is sleeved on the outside of the fixed inner cylinder 29 and connected to the baffle plate 23. The planting trough 21 is connected to the inside of the cultivation rack 1 to realize the rapid distribution of the mixed liquid. The guide plate 25 guides the mixed liquid to flow into each layer of the planting trough 21 from top to bottom. The connection between the baffle plate 23 and the connecting sleeve 24 controls the water level in the planting trough 21 by adjusting the height of the baffle plate 23 blocking the water, adapting to the water requirements of different vegetables.
[0033] Furthermore,
[0034] A water-passing plate 27 is fixedly connected to the top of the inner cylinder 29. A screw 26 is rotatably connected to the upper side of the water-passing plate 27. A cover 22 is fixedly connected to the top of the connecting sleeve 24, and the cover 22 is threaded onto the outside of the screw 26. A handle 211 is fixedly connected to the top of the screw 26. The water-passing plate 27 provides stable rotation support for the screw 26 and can also transport the water delivered by the submersible pump 32 to the top of the cultivation rack 1 to ensure water circulation.
[0035] A scale plate 28 is fixedly connected to the outer wall of the top of the fixed inner cylinder 29. A movable groove 210 adapted to the scale plate 28 is opened on the side of the connecting sleeve 24 and the cover 22 near the scale plate 28. The scale plate 28 allows the operator to intuitively observe the position and height of the baffle plate 23 and the scale value corresponding to the water level when adjusting the baffle plate 23, avoiding blind adjustment, ensuring accurate water level adjustment of each planting trough 21, meeting the needs of shallow multi-variety vegetable planting, and improving the adaptability of the device.
[0036] A sealing gasket 2301 is provided on the outer side of the water baffle 23 near the planting trough 21. The sealing gasket 2301 fills the gap between the water baffle 23 and the inner wall of the hollow cultivation rack 1, effectively preventing water in the planting trough 21 from leaking into other areas of the cultivation rack 1 and ensuring the accuracy of water level regulation.
[0037] Example 2
[0038] Improvements based on Embodiment 1: A water storage tank 5 is fixedly connected to the bottom of the cultivation rack 1, and the cultivation rack 1 and the water storage tank 5 are connected. A circulation mechanism 3 is set inside the water storage tank 5. The circulation mechanism 3 includes a submersible pump 32 installed at the bottom of the water storage tank 5, and the output end of the submersible pump 32 is connected to the fixed inner cylinder 29. The connection between the cultivation rack 1 and the water storage tank 5 allows excess water overflowing from the planting trough 21 to flow back to the water storage tank 5 naturally, realizing closed-loop water resource recycling. The submersible pump 32 transports the water in the water storage tank 5 to the fixed inner cylinder 29, and then disperses it to the inside of the hollow cultivation rack 1 through the water circulation tray 27, forming a stable water circulation and continuously providing nutrients and oxygen for the vegetables.
[0039] A filter screen 31 is fixedly connected between the water storage tank 5 and the fixed inner cylinder 29. Two sets of arc-shaped cleaning covers 33 are embedded at the top of the water storage tank 5, and the cleaning covers 33 are installed on the surface of the water storage tank 5 by connecting bolts 34. The filter screen 31 filters the water flowing back to the water storage tank 5, intercepting residual roots, impurities, etc., to prevent them from clogging the submersible pump 32 or polluting the circulating water, and ensuring the stable operation of the circulation system. The cleaning covers 33 are conveniently fixed by connecting bolts 34, and after disassembly, impurities on the surface of the filter screen 31 can be cleaned directly.
[0040] Both the filter screen 31 and the guide plate 25 have a conical structure. The conical filter screen 31 increases the contact area with the water, improves the filtration efficiency, and the intercepted impurities are deposited at the bottom under the action of gravity, reducing the impact of impurity adhesion on the filtration effect. The conical guide plate 25 is adapted to the internal space of the hollow cultivation rack 1, guiding the water to flow more smoothly to each layer of planting trough 21, avoiding water residue on the surface of the guide plate 25, and ensuring uniform liquid supply.
[0041] A ring-shaped plant light strip 212 is fixedly installed on the outer wall of the cultivation rack 1 near the cultivation chamber 4. The ring-shaped plant light strip 212 is arranged around the vegetable to provide uniform light and meet the needs of photosynthesis. Especially in indoor or balcony environments where natural light is insufficient, the light duration can be adjusted to promote vegetable growth and expand the applicable scenarios of the device.
[0042] Working principle: When using this device, lettuce seedlings are planted in the cultivation chamber 4. Then, the water level of the baffle plate 23 is adjusted according to the scale plate 28. The screw 26 is rotated by turning the handle 211. The screw drive causes the cover 22 to rise and fall along the screw 26. The connecting sleeve 24 moves synchronously with the cover 22, causing the baffle plate 23 to slide in the cultivation rack 1, thereby adjusting the water level of the planting trough 21. The mixture of water and culture medium is injected into the cultivation rack 1 through the upper side of the cultivation rack 1. The mixture is injected into the planting trough 21 from top to bottom along the guide plate 25. Excess water overflows through the baffle plate 23, is filtered by the conical filter screen 31, and enters the water storage tank 5. Then, the submersible pump 32 is started, and the filtered water is transported to the fixed inner cylinder 29 and flows into the cultivation rack 1 through the water tray 27. Excess water flows back to the water storage tank 5 to form a cycle.
[0043] After hydroponic planting is completed, nutrient solution and residual root impurities may remain in the planting trough 21. By rotating the handle 211, the screw 26 is rotated, which causes the cover 22 to rise and fall along the screw 26. The connecting sleeve 24 moves synchronously with the cover 22, which moves the baffle 23 to the bottom of the planting trough 21. This allows the residual roots, impurities and culture solution inside the planting trough 21 to be discharged into the water storage tank 5, avoiding algae growth and cross-contamination caused by residual nutrient solution or impurities, which would affect subsequent vegetable cultivation.
