Description

Technical Field

[0001] This utility model belongs to the field of hydroponic equipment technology, specifically relating to a precise control salt-tolerant rice hydroponic box. Background Technology

[0002] A rice hydroponic box is a laboratory hydroponic device specifically designed for cultivating genetically modified or specially bred salt-tolerant rice varieties. It allows researchers to observe the entire growth process of rice in water containing a certain level of salinity.

[0003] Current hydroponic boxes only include containers for holding hydroponic nutrient solution and seedling boxes for placing rice seeds. The seedling boxes are placed on top of the containers, and the rice roots grow downwards into the hydroponic nutrient solution. Researchers can observe the entire growth and development process of rice in the seedling boxes.

[0004] The existing structure described above has the following problems:

[0005] 1. It is not convenient to accurately control the amount of hydroponic nutrient solution and to automatically circulate and replace the hydroponic nutrient solution;

[0006] 2. It is inconvenient to remove a portion of the rice from the seedling box for experiments. Utility Model Content

[0007] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a precise control box for salt-tolerant rice hydroponics.

[0008] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0009] A precise control hydroponic box for salt-tolerant rice includes a hydroponic solution container and a seedling box, characterized in that it also includes an inlet pipe, an outlet pipe, a water level sensor, and a seedling tube;

[0010] Both the inlet pipe and the outlet pipe are inserted into the hydroponic solution container. The inlet pipe is connected to the inlet water pump, and the outlet pipe is connected to the outlet water pump. The water level sensor, the inlet water pump, and the outlet water pump are all electrically connected to the controller. The water level sensor is installed in the seedling box, and the probe of the water level sensor passes through the seedling box and enters the hydroponic solution container.

[0011] The seedling box is provided with several insertion holes, and the seedling tube is inserted into the insertion holes. The bottom of the seedling tube is provided with root holes and several thread holes, and a water supply line for drawing water passes through the thread holes.

[0012] This invention uses a water level sensor to detect the level of the hydroponic nutrient solution in the hydroponic container, thereby achieving precise control of the hydroponic nutrient solution. This allows the water level to adapt to the needs of different growth stages of rice (in the cultivation of salt-tolerant rice, salt, such as sodium chloride, needs to be added to the hydroponic nutrient solution). When the controller determines that the water level has reached the standard range based on the signal from the water level sensor, it sends an electrical signal to stop the inlet pump, preventing further water intake. When it is necessary to replace the hydroponic nutrient solution, the controller sends an electrical signal to start the drain pump, pumping out the hydroponic nutrient solution from the container and then driving the inlet pump to pump in the hydroponic nutrient solution. This achieves automatic replacement and circulation of the hydroponic nutrient solution, eliminating the need for manual replacement by laboratory personnel and improving the level of intelligence.

[0013] The insertion holes in the seedling box are used to insert seedling tubes. After the rice seeds are placed in the seedling tubes, they grow in a separate space and will not get tangled with the roots of rice seeds in other seedling tubes. Therefore, when the experimenter wants to take out some rice seedlings, he can directly pull out the seedling tube from the insertion hole to obtain an independent portion of rice seedlings.

[0014] The root holes are used to allow the roots of the rice seedlings to come into contact with the hydroponic nutrient solution in the hydroponic container. The threading holes are used to pass the water inlet wire, the end of which is immersed in the hydroponic nutrient solution to draw some of the solution to moisten itself, thereby providing sufficient moisture to the rice seeds in the seedling tube, which is conducive to the germination of the rice seeds and roots.

[0015] The beneficial effects of this utility model are:

[0016] 1. It can achieve precise control over the amount of hydroponic nutrient solution, so that the level of the hydroponic solution can be adapted to the needs of rice at different growth stages;

[0017] 2. It can automatically replace and circulate the hydroponic solution, eliminating the need for manual replacement by laboratory personnel and improving the level of intelligence;

[0018] 3. The seedling tube forms a separate growing space for rice. When the experimenter pulls out the seedling tube, they can obtain an independent portion of rice seedlings, which is convenient for separation. Attached Figure Description

The embodiments described herein are specific implementations of this utility model, used to illustrate the concept of this utility model; these descriptions are explanatory and exemplary, and should not be construed as limiting the implementation methods or the scope of protection of this utility model. In addition to the embodiments described herein, those skilled in the art can employ other obvious technical solutions based on the content disclosed in the claims and specification of this application. These technical solutions include those that make any obvious substitutions and modifications to the embodiments described herein.

[0038] Example 1

[0039] like Figure 1 , 2 As shown in Figures 4 and 5, this embodiment provides a precise control hydroponic box for salt-tolerant rice, including a hydroponic liquid container 1 and a seedling box 2, as well as an inlet pipe 6, an outlet pipe 7, a water level sensor 4, and a seedling tube 3.

[0040] Both the inlet pipe 6 and the outlet pipe 7 are inserted into the hydroponic solution container 1. The inlet pipe 6 is connected to the inlet water pump 8, and the outlet pipe 7 is connected to the outlet water pump 9. The water level sensor 4, the inlet water pump 8, and the outlet water pump 9 are all electrically connected to the controller. The water level sensor 4 is installed in the seedling box 2, and the probe of the water level sensor 4 passes through the seedling box 2 and enters the interior of the hydroponic solution container 1.

[0041] The seedling box 2 is provided with several insertion holes 23. The seedling tube 3 is inserted into the insertion holes 23. The bottom of the seedling tube 3 is provided with root holes 341 and several thread holes 342. A water supply line 5 for drawing water passes through the thread holes 342.

[0042] In this embodiment, the water level sensor 4 is used to detect the level of the hydroponic nutrient solution in the hydroponic solution container 1, thereby achieving precise control of the hydroponic nutrient solution and adapting the level of the hydroponic solution to the needs of different growth stages of rice. When the controller determines that the level has reached the standard range based on the signal from the water level sensor 4, it sends an electrical signal to stop the inlet pump 8 and stop adding liquid. When it is necessary to replace the hydroponic nutrient solution, the controller sends an electrical signal to start the drain pump 9, which pumps out the hydroponic nutrient solution in the hydroponic solution container 1 and then drives the inlet pump 8 to pump in the hydroponic nutrient solution. This achieves automatic replacement and circulation of the hydroponic nutrient solution without the need for manual replacement by the experimenter, thus improving the level of intelligence.

[0043] The insertion hole 23 in the seedling box 2 is used to insert the seedling tube 3. After the rice seed is put into the seedling tube 3, it grows in a separate space and will not get tangled with the roots of rice seeds in other seedling tubes 3. Therefore, when the experimenter wants to take out some rice seedlings, he can directly pull out the seedling tube 3 from the insertion hole 23 to obtain an independent part of the rice seedlings.

[0044] The root hole 341 is used to allow the roots of the rice seedlings to come into contact with the hydroponic nutrient solution in the hydroponic solution container 1. The thread hole 342 is used to pass through the water inlet 5. The end of the water inlet 5 is immersed in the hydroponic nutrient solution and draws some of the hydroponic nutrient solution to moisten itself, thereby providing sufficient moisture for the rice seeds in the seedling tube 3, which is conducive to the germination of the rice seed roots.

[0045] In some optional instances, the seedling tray 2 is provided with mounting holes 25 for installing the water level sensor 4.

[0046] Example 2

[0047] like Figure 3 , 4 As shown in Figures 6 and 7, this embodiment provides a hydroponic box for precisely controlling salt-tolerant rice. The difference from Embodiment 1 is that the outer wall of the seedling box 2 is provided with an outwardly folded edge 21, and the inner wall of the hydroponic liquid container 1 is provided with a platform 11 for supporting the folded edge 21.

[0048] The folded edge 21 is provided with a plurality of first pipe holes 22 for passing through the liquid inlet pipe 6 and second pipe holes 26 for passing through the liquid outlet pipe 7;

[0049] Platform 11 has a first threaded hole 12 at the position corresponding to the first pipe hole 22, and a second threaded hole 13 at the position corresponding to the second pipe hole 26;

[0050] The outer wall of the inlet pipe 6 is provided with a first external thread that is adapted to the first threaded hole 12, and the outer wall of the outlet pipe 7 is provided with a second external thread that is adapted to the second threaded hole 13. The outer wall of the inlet pipe 6 is provided with a first limiting ring 61 with a size larger than the first pipe hole 22, and the outer wall of the outlet pipe 7 is provided with a second limiting ring 71 with a size larger than the second pipe hole 26.

[0051] The wall of the inlet pipe 6 is provided with a strip-shaped notch 62 parallel to the axis.

[0052] In this embodiment, the platform 11 supports the folded edge 21, so that the seedling box 2 can be placed on the hydroponic liquid container 1, and the placement height of the seedling box 2 is determined by the platform 11;

[0053] The first tube hole 22 is used to pass through the liquid inlet pipe 6, so that the first external thread of the liquid inlet pipe 6 is screwed into the first threaded hole 12, thereby fixing the liquid inlet pipe 6 on the platform 11. As the first external thread and the first threaded hole 12 are continuously screwed into each other, the liquid inlet pipe 6 continues to descend until the first limiting ring 61 abuts against the upper surface of the folded edge 21. At this time, the liquid inlet pipe 6 is fixed and presses down on the seedling box 2, indirectly fixing the seedling box 2 and preventing the seedling box 2 from moving at will. The liquid outlet pipe 7 is fixed by the cooperation of the second external thread and the second threaded hole 13. Similarly, the second limiting ring 71 can also press down on the seedling box 2.

[0054] The strip-shaped notch 62 is designed to distribute the hydroponic nutrient solution. When the hydroponic nutrient solution flows down along the inlet pipe 6, it can flow out in advance at the designed strip-shaped notch 62, instead of flowing out at the bottom outlet. This can improve the mixing effect of adding hydroponic nutrient solution to the hydroponic solution container 1.

[0055] Example 3

[0056] like Figure 4 , 5 As shown, this embodiment provides a hydroponic box for precisely controlling salt-tolerant rice. The difference from embodiment 1 is that the seedling tube 3 includes a light-inlet tube 32 and a seed tube 31 connected together. The diameter of the light-inlet tube 32 is larger than that of the seed tube 31, and the diameter of the seed tube 31 is adapted to the insertion hole 23. A first magnetic ring 33 is provided at the bottom of the outer surface of the light-inlet tube 32, and a second magnetic ring 24 is provided in the seedling box 2, which is coaxially distributed with the insertion hole 23. After the seedling tube 3 is inserted into the insertion hole 23, the first magnetic ring 33 and the second magnetic ring 24 attract each other.

[0057] In this embodiment, the diameter of the light-inlet tube 32 is larger than that of the seed tube 31, which is used to expand the light-inlet space so that the rice seeds in the seed tube 31 can receive good light. When the seedling tube 3 is inserted into the insertion hole 23, in order to maintain the stability of the seedling tube 3, the first magnetic ring 33 and the second magnetic ring 24 attract each other, thereby maintaining the stability of the seedling tube 3 and preventing the seedling tube 3 from shaking.

[0058] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
