Technical Field
[0001] This utility model relates to the technical field of vegetable seedling raising devices, specifically a multi-layer three-dimensional hydroponic rack for vegetable seedling raising. Background Technology
[0002] Multi-layered hydroponic racks for vegetable seedling cultivation are modern agricultural equipment that combines vertical planting and hydroponics technologies. They are primarily used for the efficient and intensive cultivation of vegetable seedlings. Through a vertically layered design and a nutrient solution circulation system, they optimize resources and increase yields during the seedling cultivation process.
[0003] However, traditional hydroponic seedling racks for vegetables are mostly designed with fixed layer heights, resulting in low space utilization and difficulty in adapting to the growth needs of different vegetable varieties. In existing technologies, the adjustment of the layer spacing of multi-layer hydroponic racks mostly relies on manual disassembly and reassembly, which is cumbersome. Furthermore, fixed hydroponic troughs have the problem of shading in light distribution, resulting in insufficient light for seedlings in the lower layers and affecting the quality of seedling cultivation. Utility Model Content
[0004] The purpose of this invention is to provide a multi-layer three-dimensional hydroponic rack for vegetable seedling cultivation, so as to solve the problems mentioned in the background art.
[0005] The objective of this utility model can be achieved through the following technical solutions:
[0006] A multi-layer three-dimensional hydroponic rack for vegetable seedling cultivation includes a support frame and a circulating water tank. A water pump is installed in the circulating water tank. The support frame includes a base. Vertical support columns are fixedly installed at both ends of the top surface of the base. A connecting plate is fixedly connected between the top ends of the two support columns. A screw is fixedly installed between the middle of the bottom surface of the connecting plate and the middle of the top surface of the base.
[0007] Multiple sets of hydroponic components are provided between the connecting plate and the base. The two ends of the hydroponic components are slidably connected to the first conduit, and the hydroponic components are threadedly connected to the first screw.
[0008] A second conduit connects the two adjacent hydroponic components;
[0009] The outlet end of the circulating water tank is fixedly connected to an inlet pipe, and the inlet end of the circulating water tank is fixedly connected to an outlet pipe. The end of the inlet pipe away from the circulating water tank is connected to the uppermost hydroponic component, and the end of the outlet pipe away from the circulating water tank is connected to the lowermost hydroponic component.
[0010] Furthermore, the hydroponic assembly includes a lifting plate, which is slidably connected to the screw rod. A nut threaded onto the outer periphery of the screw rod is rotatably installed at the center of the top surface of the lifting plate, and a handle is fixedly installed around the outer periphery of the nut.
[0011] Limiting rings are fixedly installed at both ends of the lifting plate, and the two limiting rings are respectively connected to the two support columns through threads.
[0012] Both sides of the lifting plate are fixedly connected to adjustment components. The end of the adjustment component away from the lifting plate is fixedly installed with a hydroponic trough for placing hydroponic pots. A conduit connects the two hydroponic troughs.
[0013] Furthermore, the adjustment assembly includes a telescopic rod and an internal threaded sleeve. One end of the internal threaded sleeve is rotatably mounted at the middle position of the side of the lifting plate. The end of the internal threaded sleeve away from the lifting plate is threaded with a screw rod II. The end of the screw rod II away from the internal threaded sleeve is fixedly connected to the hydroponic tank at the corresponding position.
[0014] Two telescopic rods are provided. The two telescopic rods are fixedly installed on the side of the lifting plate near both ends. The end of the telescopic rod away from the lifting plate is fixedly connected to the hydroponic tank at the corresponding position.
[0015] A handle is fixedly installed on the outer periphery of the internal threaded sleeve.
[0016] Furthermore, the inlet pipe, outlet pipe, conduit one, and conduit two are all telescopic flexible conduits.
[0017] Furthermore, the bottom of the hydroponic tank is provided with anti-slip texture, and the edge of the tank is inclined outward to form a guide channel to prevent the nutrient solution from overflowing.
[0018] The beneficial effects of this utility model are:
[0019] 1. The lifting plate of each hydroponic unit moves vertically via a nut and screw threaded together. Turning the handle causes the nut to slide the lifting plate up and down along the limiting ring of the support column. Users can quickly adjust the layer spacing according to the plant height requirements of different vegetable varieties. The lifting plate supports continuous adjustment from the ground to the top layer without disassembling any parts.
[0020] 2. By rotating the inner threaded sleeve of the handle, the screw rod extends and retracts, adjusting the horizontal distance between the hydroponic trough and the lifting plate. This creates a stepped layout between the upper and lower hydroponic troughs. The stepped arrangement ensures that the leaves of each layer of seedlings are fully exposed to light, preventing the upper layer from blocking the lower layer. Attached Figure Description

Detailed Implementation
[0028] 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.
[0029] Example 1:
[0030] Please see Figures 1-4 In this embodiment of the utility model, a multi-layer three-dimensional hydroponic rack for vegetable seedling cultivation includes a support frame and a circulating water tank 19. A water pump is installed in the circulating water tank 19. The support frame includes a base 1. Vertical support columns 2 are fixedly installed at both ends of the top surface of the base 1. A connecting plate 3 is fixedly connected between the top ends of the two support columns 2. A screw 4 is fixedly installed between the middle of the bottom surface of the connecting plate 3 and the middle of the top surface of the base 1.
[0031] Multiple sets of hydroponic components 9 are provided between the connecting plate 3 and the base 1. The two ends of the hydroponic components 9 are slidably connected to the conduit 7, and the hydroponic components 9 are threadedly connected to the screw 4.
[0032] A second guide tube 8 connects two adjacent hydroponic components 9;
[0033] The outlet end of the circulating water tank 19 is fixedly connected to the inlet pipe 5, and the inlet end of the circulating water tank 19 is fixedly connected to the outlet pipe 6. The end of the inlet pipe 5 away from the circulating water tank 19 is connected to the uppermost hydroponic component 9, and the end of the outlet pipe 6 away from the circulating water tank 19 is connected to the lowermost hydroponic component 9.
[0034] The circulating water tank 19 uses a water pump to deliver the nutrient solution through the inlet pipe 5 to the top hydroponic component 9, which then flows into the hydroponic tanks 10 below through the second conduit 8, and finally returns to the circulating water tank through the outlet pipe 6, forming a closed-loop circulation system.
[0035] The hydroponic component 9 includes a lifting plate 11, which is slidably connected to the screw 4. A nut 16 threaded around the screw 4 is rotatably installed at the center of the top surface of the lifting plate 11. A handle 17 is fixedly installed around the nut 16.
[0036] Limiting rings 12 are fixedly installed at both ends of the lifting plate 11, and the two limiting rings 12 are respectively connected to the two support columns 2 through threads.
[0037] Adjustment components are fixedly connected to both sides of the lifting plate 11. A hydroponic trough 10 for placing hydroponic pots is fixedly installed at the end of the adjustment component away from the lifting plate 11. A conduit 7 is connected between the two hydroponic troughs 10.
[0038] Among them, the inlet pipe 5, outlet pipe 6, conduit 7, and conduit 8 are all telescopic flexible conduits. The inlet pipe 5, outlet pipe 6, and conduit 7 and conduit 8 connecting each layer are all made of corrosion-resistant TPU flexible tubing, which can automatically extend and retract with the rise and fall of the hydroponic component 9, avoiding the twisting or leakage caused by changes in the height of traditional rigid pipes.
[0039] The hydroponic trough 10 has anti-slip grooves on the bottom, and the edges of the trough slope outward to form a guide channel to prevent the nutrient solution from overflowing. The anti-slip grooves on the bottom of the hydroponic trough 10 can both fix the hydroponic pot and prevent scratching the roots.
[0040] When using this utility model:
[0041] The circulating water tank 19 has a built-in high-efficiency water pump that delivers the nutrient solution at a controllable flow rate to the hydroponic tank 10 of the uppermost hydroponic component 9 through the inlet pipe 5. Under gravity, the nutrient solution flows layer by layer to the lower hydroponic tanks 10 through the second conduit 8, and finally returns to the circulating water tank 19 through the outlet pipe 6, forming a closed loop. During this process, the system can be equipped with a filter module to purify the nutrient solution and prevent impurities from clogging the pipes; at the same time, the circulating water tank 19 has a built-in temperature control device that can stabilize the nutrient solution temperature at 18-25℃, meeting the growth needs of most vegetable seedlings. By adjusting the water pump power or adding a flow valve, the liquid level in each layer of the hydroponic tank 10 can be precisely controlled, ensuring that the roots are in full contact with the nutrient solution while avoiding oxygen deficiency.
[0042] The lifting plate 11 of each hydroponic component 9 moves vertically via a nut 16 threadedly engaging with a screw 4. When the handle 17 is turned, the nut 16 causes the lifting plate 11 to slide up and down along the limiting ring 12 of the support column 2. Users can quickly adjust the layer spacing according to the plant height requirements of different vegetable varieties. The lifting plate 11 supports continuous adjustment from the ground to the top layer without disassembling any parts.
[0043] Example 2:
[0044] Please see Figure 3 and Figure 4 Based on embodiment 1, the adjustment component includes a telescopic rod 13 and an internal threaded sleeve 15. One end of the internal threaded sleeve 15 is rotatably installed at the middle position of the side of the lifting plate 11. The end of the internal threaded sleeve 15 away from the lifting plate 11 is threaded with a screw rod 14. The end of the screw rod 14 away from the internal threaded sleeve 15 is fixedly connected to the hydroponic tank 10 at the corresponding position.
[0045] Two telescopic rods 13 are provided. The two telescopic rods 13 are fixedly installed on the side of the lifting plate 11 near both ends. The end of the telescopic rod 13 away from the lifting plate 11 is fixedly connected to the hydroponic tank 10 at the corresponding position.
[0046] A handle 18 is fixedly installed on the outer periphery of the internal threaded sleeve 15.
[0047] Rotating the inner threaded sleeve 15 by the handle 18 drives the screw 14 to extend and retract, adjusting the horizontal distance between the hydroponic tank 10 and the lifting plate 11. This creates a stepped layout of the upper and lower hydroponic tanks 10. The stepped arrangement ensures that the leaves of each layer of seedlings are fully exposed to light, preventing the upper layer from blocking the lower layer.
[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
