Description

Technical Field

[0001] This utility model belongs to the technical field of soilless cultivation devices, and in particular relates to a soilless cultivation device for organic agricultural products. Background Technology

[0002] Soilless cultivation technology, especially hydroponics, is widely used in the cultivation of organic agricultural products due to its clean environment and high resource utilization rate. During crop growth, different growth stages require different water depths for the roots. For example, seedlings need shallow water levels to promote root respiration, while vigorous growth requires deeper water levels to ensure sufficient water and nutrient supply. Existing multi-layer hydroponic systems typically use fixed overflow pipes to control the water level, which cannot be changed once set. Adjustments require manual replacement of overflow pipes at different heights, which is cumbersome, inefficient, and makes precise control difficult. Summary of the Invention

[0003] The purpose of this invention is to provide a soilless cultivation device for organic agricultural products to solve the problems existing in the prior art.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A hydroponic cultivation device for organic agricultural products includes a mounting frame on which several hydroponic tubes are fixed. One end of each hydroponic tube is threadedly connected to an end cap, and the other end is connected to a water inlet pipe. The several water inlet pipes are connected to a common main water inlet pipe. The closed end of the end cap is connected to an outlet pipe offset from its axis. Several turbine teeth are provided on the outer wall of the end cap. A worm gear is rotatably connected to the mounting frame. The end cap meshes with the worm gear through the turbine teeth. The worm gear is connected to a drive device. A drain pipe is fixed on the mounting frame, and the outlet pipe is connected to the drain pipe through a flexible hose.

[0006] Furthermore, the mounting frame has several vertical uprights with several through holes. Several sleeves are fitted onto the uprights, and horizontal supports are provided on both sides of the sleeves. The horizontal supports on both sides of the sleeves are located on opposite sides of the mounting frame. The sleeves are fixed to the mounting frame by bolt pairs that pass through the sleeves and through holes.

[0007] Furthermore, pipe clamps are bolted to the cross braces, and the hydroponic pipe is fixed to several cross braces on the same horizontal axis by the pipe clamps.

[0008] Furthermore, there are two worm gears, which are connected by a sprocket structure, and the two worm gears respectively mesh with end caps located on both sides of the mounting bracket.

[0009] Furthermore, the drive device is a servo motor or a stepper motor, which is fixed on the mounting bracket, and the output end of the drive device is connected to either of the two worm gears.

[0010] Furthermore, a groove is provided at one end of the hydroponic tube connection cap, and a sealing ring is installed in the groove.

[0011] Furthermore, the hydroponic tube has several hydroponic holes, and hydroponic cups can be detachably inserted into the hydroponic holes.

[0012] This utility model has the following beneficial effects:

[0013] 1. This invention controls the rotation of a worm gear via a drive device, which in turn drives multiple end caps to rotate and move axially, thereby adjusting the height of the water outlet and achieving precise control of the liquid level inside the hydroponic tube. This meets the different needs of crops at different growth stages for root immersion depth, optimizes the root environment, and significantly improves crop yield and quality.

[0014] 2. Using a motor (especially a servo motor or stepper motor) as the drive device allows for easy connection to an external timer or intelligent controller, enabling automated programming control of the liquid level adjustment process and significantly reducing the labor intensity and management costs of manual operation.

[0015] 3. Utilizing the inherent self-locking characteristics of the worm gear drive, the end cap position is automatically locked when the drive device stops working, effectively preventing the liquid level from changing on its own due to water pressure fluctuations or equipment vibration, thus ensuring the stability of the cultivation environment.

[0016] 4. It adopts a multi-layer three-dimensional cultivation design, and through the height adjustment mechanism that combines the sleeve and adjustment hole, the spacing of each layer of hydroponic tubes can be flexibly configured to adapt to the light and space requirements of different crops at different growth stages, thereby maximizing the planting efficiency per unit area.

[0017] 5. By linking the two worm gears through a sprocket structure, all end caps on both sides of the mounting bracket can be driven synchronously with only one drive device, ensuring the consistency of liquid level adjustment on both sides, while simplifying the structure and reducing manufacturing costs.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with specific embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the scope of the utility model.

[0024] like Figure 1-4 As shown, a soilless cultivation device for organic agricultural products includes a mounting frame 1. Several hydroponic tubes 3 are fixed on the mounting frame 1. One end of each hydroponic tube 3 is threadedly connected to an end cap 4, and the other end is connected to a water inlet pipe 6. Several water inlet pipes 6 are connected to the same main water inlet pipe 7. The closed end of the end cap 4 is connected to an outlet pipe 8 that is offset from its axis. Several turbine teeth 5 are provided on the outer wall of the end cap 4. A worm gear 9 is rotatably connected to the mounting frame 1. The end cap 4 meshes with the worm gear 9 through the turbine teeth 5. The worm gear 9 is connected to a drive device 10. A drain pipe 11 is fixed on the mounting frame 1. The outlet pipe 8 is connected to the drain pipe 11 through a flexible hose 12.

[0025] Mounting bracket 1 has several vertical uprights 16, with several through holes 15 on the uprights 16. Several sleeves 13 are sleeved on the uprights 16. Horizontal supports 2 are provided on both sides of the sleeves 13. The horizontal supports 2 on both sides of the sleeves 13 are located on opposite sides of the mounting bracket 1. The sleeves 13 are fixed to the mounting bracket 1 by bolt pairs 14 that pass through the sleeves 13 and the through holes 15.

[0026] Pipe clamps 21 are bolted to the cross brace 2, and the hydroponic pipe 3 is fixed to several cross braces 2 on the same horizontal axis by the pipe clamps 21.

[0027] There are two worm gears 9, which are connected by a sprocket structure 22. The two worm gears 9 are respectively engaged with end caps 4 located on both sides of the mounting bracket 1.

[0028] The drive device 10 is a servo motor or a stepper motor. The drive device 10 is fixed on the mounting bracket 1, and the output end of the drive device 10 is connected to either of the two worm gears 9.

[0029] The hydroponic tube 3 has a groove 17 at one end of the connecting end cap 4, and a sealing ring 18 is provided in the groove 17. The sealing ring 18 is preferably made of a material with a low coefficient of friction, such as TPU or PTFE.

[0030] The hydroponic tube 3 has several hydroponic holes 20, and a hydroponic cup 19 can be detachably inserted into each hydroponic hole 20.

[0031] The working principle of this utility model is as follows:

[0032] When the liquid level needs to be adjusted, the drive unit 10 is activated. The output shaft of the drive unit 10 drives the worm gear 9 connected to it to rotate. The worm gear 9 drives the end cover 4 to rotate by meshing with the worm gear 5 on the end cover 4. Since the end cover 4 and the hydroponic tube 3 are connected by threads, the rotational motion of the end cover 4 is converted into axial linear motion (screwing in or out) relative to the hydroponic tube 3. Since the outlet pipe 8 is eccentrically fixed at the closed end of the end cover 4, the height of the outlet changes accordingly when the end cover 4 moves axially. After the nutrient solution is injected into the hydroponic tube 3 through the main inlet pipe 7 and the inlet pipe 6, the liquid level will continue to rise until it reaches the new height of the outlet pipe 8 and begins to overflow. The overflowing nutrient solution flows into the main drain pipe through the hose 12, thereby achieving precise liquid level setting.

[0033] The above embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention.

[0034] The technologies, shapes, and structures not described in detail in this utility model are all known technologies.
