Description

Technical Field

[0001] This invention relates to the field of Codonopsis pilosula seedling technology, and in particular to a nutrient solution delivery device for Codonopsis pilosula seedlings. Background Technology

[0002] Codonopsis pilosula is a traditional Chinese medicine that tonifies qi and strengthens the spleen. It can enhance physical strength, improve fatigue, promote digestion and absorption, and improve immunity. It is often used to relieve symptoms such as physical fatigue, poor appetite, and pale complexion caused by insufficient qi and blood.

[0003] Nutrient solution seedling cultivation is a modern seedling cultivation method. It involves adding a nutrient solution suitable for plant growth to a soilless medium and artificially cultivating the seedlings in an incubator. It is suitable for the rapid cultivation of Codonopsis pilosula.

[0004] During the nutrient solution seedling cultivation process, the high nutrient content of the nutrient solution makes it easy for bacteria to grow, leading to water quality deterioration and causing root rot in the Codonopsis seedlings that have been soaked for a long time. In order to avoid root rot, the nutrient solution needs to be changed regularly. However, conventional nutrient solution delivery devices only drain and replace the nutrient solution and cannot clean the roots of the Codonopsis seedlings, so root rot is still likely to occur after the nutrient solution is changed. Summary of the Invention

[0005] The purpose of this invention is to provide a nutrient solution delivery device for Codonopsis pilosula seedling cultivation, which aims to solve or improve at least one of the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention provides the following solution: The present invention provides a nutrient solution delivery device for Codonopsis pilosula seedling cultivation, comprising:

[0007] Seedling box;

[0008] Multiple support rings are arranged inside the seedling box. Seedling cups are placed on the support rings. The seedling cups have a filter structure. A rotating ring is rotatably arranged on the support ring. Multiple spray pipes are fixedly connected to the rotating ring. The spraying ends of the spray pipes face the axis of the support ring.

[0009] The three-way valve is connected to a cleaning water pipe, a nutrient solution pipe, and a connecting pipe, respectively, and the connecting pipe is connected to multiple spray pipes.

[0010] A drive mechanism is provided on the seedling box, and the drive mechanism is used to drive the multiple rotating rings to rotate.

[0011] Optionally, the drive mechanism includes:

[0012] Multiple worm gears are fixedly connected to multiple rotating rings;

[0013] A rotating rod is rotatably connected inside the seedling box. Multiple worm gears are coaxially fixedly connected to the rotating rod, and the multiple worm gears correspond one-to-one with and mesh with the multiple worm wheels.

[0014] A drive source is used to drive the rotating rod to rotate.

[0015] Optionally, the driving source includes:

[0016] An electric slide rail is installed on the seedling box, and an electric slider is slidably fitted on the electric slide rail. An installation plate is fixedly connected to the electric slider.

[0017] A transmission rod is rotatably connected inside the seedling box. The transmission rod is driven by the rotating rod through a gear set. A spiral groove is provided on the transmission rod, and a sliding sleeve with a guide slider is slidably fitted inside the spiral groove. The sliding sleeve is fixedly connected to the mounting plate.

[0018] Optionally, the gear set includes:

[0019] The first spur gear is fixedly connected to the rotating rod;

[0020] The second spur gear is fixedly connected to the transmission rod, and the second spur gear meshes with the first spur gear.

[0021] Optionally, the connecting pipe includes multiple connecting segments, and a support ring is fixedly connected between two adjacent connecting segments. The two connecting segments at both ends are fixedly connected to the seedling box. A connecting cavity is opened in the support ring, and the connecting cavity is connected to the connecting segment. Multiple connecting ports are opened on the rotating ring and are connected to the connecting cavity. The multiple connecting ports are connected to multiple spray pipes.

[0022] Optionally, the support ring is provided with a support slide for supporting the rotating ring.

[0023] Optionally, there is a gap between the bottom of the seedling cup and the inner bottom surface of the seedling box. A cylinder is fixedly installed on the mounting plate. A telescopic spring rod is fixedly connected to the output end of the cylinder. A scraper is fixedly connected to the telescopic spring rod. The scraper is used to abut against the inner bottom surface of the seedling box.

[0024] Optionally, the seedling box is provided with slopes at both ends along the sliding direction of the electric slider.

[0025] Optionally, a drain pipe with an opening and closing valve is provided at the slope.

[0026] Optionally, the bottom surface of the seedling box is provided with multiple support legs.

[0027] This invention discloses the following technical effects: When the nutrient solution needs to be replaced, the nutrient solution is drained from the seedling box. Then, a cleaning water pipe is connected to clean water, and clean water is pumped into the spray pipe. A drive mechanism drives multiple rotating rings to rotate, which in turn drive multiple spray pipes on them to rotate circumferentially around the seedling cup. The seedling cup has a filter screen structure, so the cleaning water sprayed from the spray pipe cleans the roots of the Codonopsis pilosula seedlings in the seedling cup, avoiding the presence of too much old nutrient solution on the roots, reducing root rot, and effectively improving the survival rate of the Codonopsis pilosula seedlings.

[0035] Excessive concentrations of nutrients such as nitrogen and phosphorus in the nutrient solution can promote algae growth, leading to water quality deterioration. Meanwhile, excessively high electrical conductivity or nutrient deficiency can also impair root nutrient absorption, causing root rot.

[0036] The replacement cycle for nutrient solution seedling cultivation needs to be determined comprehensively based on the crop type, growth stage, and solution condition.

[0037] Leafy greens (such as lettuce and spinach): Replace every 7-10 days;

[0038] Solanaceous vegetables (such as tomatoes and cucumbers): Replace every 3-5 days;

[0039] For long-term crops (such as fruit trees and flowers): Replace every 1-2 weeks, or after each planting.

[0040] Water pollution (such as turbidity, odor, algae growth): must be replaced immediately;

[0041] pH fluctuations (exceeding the range of 6-7.5): require immediate adjustment or replacement;

[0042] In high-temperature environments (such as summer): it is recommended to shorten the replacement period to 5 days or weekly;

[0043] In low-temperature environments (such as winter): the interval can be extended to 10-15 days or replaced monthly.

[0044] Existing Chinese patent CN108064647A discloses a special nutrient solution for soilless seedling cultivation of Codonopsis pilosula. The key technical issue is the cultivation of Codonopsis pilosula seedlings in a nurturing room. However, traditional Codonopsis pilosula seedling cultivation is done outdoors, relying entirely on rainfall and unpredictable drought or flooding. Furthermore, years of pesticide and heavy metal pollution of the soil severely impacts the yield and quality of Codonopsis pilosula seedlings. Therefore, adopting soilless facility seedling cultivation technology is the only way to solve these problems. The key to achieving soilless seedling cultivation is nutrient supply. However, general facility cultivation techniques cannot meet the requirements of Codonopsis pilosula for a mild and cool environment. Meanwhile, some researchers have attempted to use a mixture of plant residues, grapefruit peel, chestnut shells, plant extracts, biogas residue, and animal manure as a soilless cultivation substrate and nutrient source for Codonopsis pilosula. However, this either increases the preparation cost or contains potential sources of pest and disease contamination, making Codonopsis pilosula seedlings susceptible to pests and diseases. The proposed technical solution contains the following components per liter of nutrient solution: potassium dihydrogen phosphate 40 mg; magnesium sulfate 160 mg; calcium nitrate tetrahydrate 220 mg; ferrous sulfate heptahydrate 4 mg. g; EDTA 10mg; boric acid 0.006mg; manganese sulfate 0.05mg; potassium nitrate 160mg; zinc sulfate 0.02mg; copper sulfate 0.000025mg; molybdic acid 0.0004mg; ammonium nitrate 20mg; potassium iodide 0.002mg; cobalt chloride 0.00005mg; balance is water. The combined components contain all the essential macro and micro elements necessary for the growth and development of Codonopsis pilosula seedlings, and the components work synergistically to promote the growth and development of Codonopsis pilosula seedlings. The soilless green seedling nutrient solution provided by this invention, combined with the soilless green seedling cultivation method, produces uniform Codonopsis pilosula seedlings with an average height of 35cm, stem diameter of 0.3cm, low disease incidence (0.01-1.00%), and a yield of 280,000-400,000 seedlings per mu (approximately 0.067 hectares). Compared with traditional Codonopsis pilosula seedling cultivation methods, the yield per mu is increased by 45 times, greatly improving production efficiency and reducing the cost of Codonopsis pilosula seedlings.

[0045] Existing Chinese patent CN115669525A discloses a nutrient solution delivery device for Codonopsis pilosula seedlings. The technical problem addressed is that Codonopsis pilosula seedlings are typically grown in greenhouses, resulting in a long growth cycle and slow development. To address this, we propose a nutrient solution delivery device for Codonopsis pilosula seedlings. The technical solution involves the user first opening the glass cover, placing the seedlings inside the cultivation structure, and then closing the glass cover. A variable frequency motor is then activated, rotating the agitator, scraper, and scraper brush to stir the nutrient solution and prevent sedimentation. The solution is then directed to the delivery structure via a control mechanism. A small pump activates the nutrient solution, which flows into the spraying structure and is then sprayed out through the outlet and orifice into the Codonopsis pilosula culture vessel, allowing the seedlings to grow and develop vigorously.

[0046] Existing Chinese patent CN113994882A discloses an intelligent nutrient solution delivery system for vegetable cultivation. The technical problem addressed is that traditional hydroponics for vegetable cultivation often employs a fixed cultivation method. Because the cultivation pots are fixedly distributed in various cultivation chambers, and the light conditions in each chamber differ, vegetables in some pots grow vigorously due to ample light, while those in others show weak growth due to insufficient light, affecting both yield and quality. It is also difficult to systematically control the quality of vegetables in each cultivation chamber. Therefore, an improvement is needed. The technical solution involves starting a motor to drive the first rotating rod to rotate. The rotation of the first rotating rod drives the first sprocket to rotate. Under the transmission of the chain, the rotation of the first sprocket drives the rotation of the second sprocket. Through the connection of the support rod and the cooperation between the first sliding groove and the first slider, the chain moves and drives the hanging rod to move. The movement of the hanging rod moves the cultivation pot. Through the cooperation between the second sliding groove and the second slider, the movement of the cultivation pot moves the first steel pipe. Thus, each cultivation pot moves along the track, ensuring that each cultivation pot receives light for photosynthesis, guaranteeing the quality of the vegetables in each cultivation pot, and facilitating systematic control of the light conditions of the vegetables in the cultivation pot.

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0049] Reference Figures 1-5 This invention provides a nutrient solution delivery device for Codonopsis pilosula seedlings, comprising:

[0050] Seedling box 1;

[0051] Multiple support rings 2 are set inside the seedling box 1. Seedling cups 3 are placed on the support rings 2. The seedling cups 3 have a filter screen structure. A rotating ring 4 is rotatably set on the support rings 2. Multiple spray pipes 5 are fixedly connected to the rotating rings 4. The spraying ends of the spray pipes 5 face the axis of the support rings 2.

[0052] The three-way valve 6 is connected to the cleaning water pipe 7, the nutrient solution pipe 8 and the connecting pipe 9 respectively. The connecting pipe 9 is connected to multiple spray pipes 5.

[0053] The drive mechanism is installed on the seedling box 1 and is used to drive multiple rotating rings 4 to rotate.

[0054] When the nutrient solution needs to be changed, the nutrient solution is drained from the seedling box 1. Then, the cleaning water is connected to the cleaning water through the cleaning water pipe 7, and the cleaning water is pumped into the spray pipe 5. The drive mechanism drives multiple rotating rings 4 to rotate, and the rotating rings 4 drive multiple spray pipes 5 on them to rotate circumferentially around the seedling cup 3. The seedling cup 3 has a filter structure, so the cleaning water sprayed from the spray pipe 5 cleans the roots of the Codonopsis seedlings in the seedling cup 3, avoiding the presence of too much old nutrient solution on the roots of the Codonopsis seedlings, reducing root rot, and effectively improving the survival rate of the Codonopsis seedlings. After the roots of the Codonopsis seedlings are cleaned, the nutrient solution is connected to the nutrient solution through the nutrient solution pipe 8, and the nutrient solution is pumped into the spray pipe 5. The spray pipe 5 sprays the nutrient solution into the seedling box 1, so that the nutrient solution soaks the roots of the Codonopsis seedlings for seedling cultivation.

[0055] In one embodiment of the present invention, the driving mechanism includes:

[0056] Multiple worm gears 10 are fixedly connected to multiple rotating rings 4;

[0057] Rotating rod 11 is rotatably connected inside seedling box 1. Multiple worm gears 12 are coaxially fixedly connected to rotating rod 11. Multiple worm gears 12 correspond one-to-one with multiple worm wheels 10 and mesh with each other.

[0058] The drive source is used to drive the rotating rod 11 to rotate.

[0059] The rotating rod 11 is driven to rotate, which in turn drives multiple worm gears 12 to rotate. The worm gears 12 then drive the worm wheel 10 to rotate, causing the rotating ring 4 to rotate, thus making the multiple rotating rings 4 rotate synchronously.

[0060] In one embodiment of the present invention, the driving source includes:

[0061] An electric slide rail 13 is set on the seedling box 1. An electric slider 14 is slidably fitted on the electric slide rail 13. An installation plate 15 is fixedly connected to the electric slider 14.

[0062] The transmission rod 16 is rotatably connected inside the seedling box 1. The transmission rod 16 is connected to the rotating rod 11 through a gear set. The transmission rod 16 is provided with a spiral groove 17. A sliding sleeve 18 with a guide slider is slidably fitted inside the spiral groove 17. The sliding sleeve 18 is fixedly connected to the mounting plate 15.

[0063] In one embodiment of the present invention, the gear set includes:

[0064] The first spur gear 19 is fixedly connected to the rotating rod 11;

[0065] The second spur gear 20 is fixedly connected to the transmission rod 16, and the second spur gear 20 meshes with the first spur gear 19.

[0066] The electric slide rail 13 drives the electric slider 14 to slide, which in turn drives the mounting plate 15 to slide synchronously. The mounting plate 15 then drives the sliding sleeve 18 to slide. The guide slider on the sliding sleeve 18 cooperates with the spiral groove 17, which causes the transmission rod 16 to rotate. Through the meshing of the second spur gear 20 and the first spur gear 19, the rotating rod 11 rotates.

[0067] In one embodiment of the present invention, the connecting pipe 9 includes multiple connecting segments, a support ring 2 is fixedly connected between two adjacent connecting segments, two connecting segments at both ends are fixedly connected to the seedling box 1, a connecting cavity 21 is opened in the support ring 2, the connecting cavity 21 is connected to the connecting segments, and multiple connecting ports 22 are opened on the rotating ring 4, which are connected to the connecting cavity 21, and the multiple connecting ports 22 are connected to multiple spray pipes 5.

[0068] Multiple support rings 2 are fixedly connected to the seedling box 1 through multiple connecting segments, and multiple connecting segments are kept in a connected state by setting a connecting cavity 21 in the support ring 2, thereby keeping multiple connecting cavities 21 in a connected state. Then, cleaning water or nutrient solution can enter the spray pipe 5 through the connecting port 22 connected by the connecting cavity 21, and the cleaning water or nutrient solution can be pumped out with the help of external pump force.

[0069] In one embodiment of the present invention, the support ring 2 is provided with a support slide 23 for supporting the rotating ring 4.

[0070] In one embodiment of the present invention, there is a gap between the bottom end of the seedling cup 3 and the inner bottom surface of the seedling box 1. A cylinder 24 is fixedly installed on the mounting plate 15. A telescopic spring rod 25 is fixedly connected to the output end of the cylinder 24. A scraper 26 is fixedly connected to the telescopic spring rod 25. The scraper 26 is used to abut against the inner bottom surface of the seedling box 1.

[0071] Because nutrients in the nutrient solution will precipitate, in order to avoid the precipitated nutrient solution adhering to the bottom surface of the seedling box 1 and affecting the quality of the new nutrient solution, the cylinder 24 drives the telescopic spring rod 25 to drive the scraper 26 to press against the inner bottom surface of the seedling box 1. While the mounting plate 15 slides, the scraper 26 slides and cleans along the gap between the inner bottom surface of the seedling box 1 and the seedling cup 3. In conjunction with the spray pipe 5, cleaning water is sprayed into the seedling box 1, thereby preventing residual old nutrients from adhering to the seedling box 1.

[0072] When there is no need to clean the bottom of the seedling box 1, the cylinder 24 drives the scraper 26 to lift and remove the nutrient solution from the seedling box 1.

[0073] In one embodiment of the present invention, the seedling box 1 is provided with slopes 27 at both ends along the sliding direction of the electric slider 14.

[0074] In one embodiment of the present invention, a drain pipe 29 with an opening and closing valve 28 is provided at the slope 27.

[0075] By setting slopes 27 at both ends of the seedling box 1, the old nutrients cleaned by the scraper 26 can flow into the drain pipe 29 and be discharged from the seedling box 1 by the guidance of the slopes 27.

[0076] In one embodiment of the present invention, the bottom surface of the seedling box 1 is provided with a plurality of support legs 30.

[0077] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0078] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
