Description

Technical Field

[0001] This invention relates to the field of Chinese medicinal herb cultivation technology, and in particular to a Chinese medicinal herb cultivation and seedling raising device and system. Background Technology

[0002] Traditional Chinese medicine (TCM) is a unique medical theory in China, and major hospitals have TCM departments. With increasing emphasis on health, the demand for Chinese medicinal herbs is gradually increasing, necessitating large-scale cultivation. To ensure the survival rate and quality of Chinese medicinal herbs, seedlings must first be cultivated and then transplanted into the ground. Currently, the traditional method involves cultivating all seedlings in a single seedling pot. This leads to different transplanting times for different types of herbs. Transplanting from the same pot requires turning the soil, which inevitably affects the normal growth of other seedlings, causing them to loosen or damage their roots, resulting in lower seedling quality. Furthermore, transplanting from a single pot requires digging up the soil, reducing efficiency.

[0003] In the existing technology, a first and a second clip are set on the turntable. The first and the second clips are interlocked and inserted into the slots. Chinese medicinal herbs can be cultivated in the first and the second clips. When it is time to transplant the Chinese medicinal herbs, the first and the second clips can be directly removed from the slots and then separated. This will not damage the root system of the Chinese medicinal herbs and greatly facilitates the transplantation of Chinese medicinal herbs.

[0004] However, in the aforementioned existing technologies, when cultivating Chinese medicinal herbs, it is usually necessary to cultivate multiple varieties. Different varieties have different growth cycles and growth rates, and the cultivation space required also varies depending on the variety of Chinese medicinal herbs. In the traditional cassette seedling cultivation method, multiple cassettes are all the same size, which not only cannot accommodate different varieties of seedlings, but also the spacing between the cassettes cannot be adjusted. Once the seedlings have grown, the spacing becomes too close, which will affect the growth of adjacent seedlings. Therefore, it is not possible to flexibly install seedling cassettes of different sizes, which means that the seedling cultivation device can only cultivate seedlings of the same variety of Chinese medicinal herbs, which is very inconvenient. Summary of the Invention

[0005] The purpose of this invention is to provide a Chinese herbal medicine planting and seedling cultivation device and system, which solves the problem in the prior art that the seedling sleeves of different sizes cannot be flexibly installed, which makes the seedling cultivation device only able to cultivate the same type of Chinese herbal medicine seedlings, which is very inconvenient.

The two electromagnets are respectively disposed on the inner wall of the groove and the locking block connecting plate.

[0012] The supporting unit includes two fixed cylinders, two telescopic rods, two third springs, a lever, and a supporting connecting plate. The two fixed cylinders are positioned above the seedling pot. The two telescopic rods are slidably connected to the corresponding fixed cylinders. The two ends of the two third springs are movably connected to the inner wall of the fixed cylinder and one end of the telescopic rod, respectively. The other ends of the two telescopic rods are fixedly connected to the supporting connecting plate. The lever is positioned above the supporting connecting plate, and the rubber supporting plate is positioned on one side of the supporting connecting plate.

Detailed Implementation

[0026] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0027] Please see Figures 1 to 6 This invention provides a Chinese medicinal herb cultivation and seedling raising device, including a seedling box 1, a water storage unit, multiple irrigation nozzles 2, a temperature sensor 3, two ventilation openings 4, a support plate 5, multiple seedling pots 6, and multiple installation components. The installation components include telescopic columns 7 and limiting units. The support plate 5 has a groove 8. Two abutment units and two rubber abutment plates 9 are arranged above the seedling pots 6. The water storage unit includes a water tank 10, a first water pump 11, a water inlet pipe 12, a water delivery pipe 13, and a water trough 14. The limiting unit includes a sealing ring 15 and a first spring. The device includes a spring 16, a limiting block 17, multiple locking blocks 18, a locking block connecting plate 19, and a retraction mechanism. The retraction mechanism includes multiple second springs 20 and two electromagnets 21. The supporting unit includes two fixed cylinders 22, two telescopic rods 23, two third springs 24, a lever 25, and a supporting connecting plate 26. The Chinese herbal medicine planting and seedling raising device also includes a recycling unit, a glass disassembly plate 27, and a glass rotating plate 28. The recycling unit includes a second water pump 29, a filter plate 30, an inclined plate 31, and a recycling water pipe 32. The support plate 5 has multiple return holes 33.

[0028] The water storage unit is located on one side of the seedling box 1, multiple irrigation nozzles 2 are located on the inner top wall of the seedling box 1, the temperature sensor 3 is located on the inner wall of the seedling box 1, two ventilation openings 4 are located on the seedling box 1 and on both sides of the temperature sensor 3, the support plate 5 is located inside the seedling box 1, multiple seedling pots 6 are sequentially placed above the support plate 5, the support plate 5 has a groove 8, the telescopic column 7 is slidably connected to the support plate 5, the limiting unit is located inside the groove 8, one end of the telescopic column 7 is located inside the groove 8 and is adapted to the limiting unit; two abutment units are symmetrically arranged above the seedling pots 6, two rubber abutment plates 9 are respectively arranged on the corresponding abutment units, and the rubber abutment plates 9 are adapted to the outer wall of the telescopic column 7. When cultivating Chinese medicinal herbs, select suitable seedling trays 6 for different herbs, and place the seedling trays 6 of different sizes on top of the support plate 5 inside the seedling box 1, positioned on multiple telescopic columns 7. Then, press down on the seedling trays 6, causing the telescopic columns 7 to move downwards. The limiting unit then limits the telescopic columns 7, causing the telescopic columns 7 below the seedling trays 6 to move downwards, while the telescopic columns 7 around the seedling trays 6 remain in their original positions. At this point, the supporting unit rebounds, causing the rubber supporting plate to... 9 and the telescopic column 7 abut against each other, thereby completing the limiting and fixing of the seedling tray 6; a fan is provided inside the ventilation port 4. When the fan inside the ventilation port 4 is turned on, one of the two ventilation ports 4 will take in air and the other will take out air to ventilate the inside of the seedling box 1. The temperature sensor 3 can detect the temperature inside the seedling box 1 and set a preset value. When the temperature is higher than the preset value, the fan speed will be increased to accelerate the ventilation and heat dissipation effect. If the temperature is lower than the preset value, the fan speed will be reduced to avoid excessive temperature drop affecting the growth of Chinese medicine.

[0029] Secondly, the water tank 10 is located on one side of the seedling box 1, the first water pump 11 is located inside the water tank 10, the water inlet pipe 12 is connected to the water tank 10, one end of the water delivery pipe 13 is connected to the outlet of the first water pump 11, and the other end of the water delivery pipe 13 passes through the water tank 10 and the seedling box 1, and is connected to the top of the water trough 14. The water trough 14 is located on the inner top wall of the seedling box 1, and multiple irrigation nozzles 2 are sequentially arranged below the water trough 14. The water tank 10 stores irrigation water, which can be added through the water inlet pipe 12. When irrigation is needed, the first water pump 11 is started to pump water into the water delivery pipe 13, which then enters the water trough 14, and then sprays it evenly from the multiple irrigation nozzles 2, irrigating the multiple seedling pots 6 from top to bottom.

[0030] Meanwhile, the sealing ring 15 is fixedly connected to the support plate 5 and is located above the support plate 5. The sealing ring 15 is sleeved on the outer wall of the telescopic column 7. The two ends of the first spring 16 are movably connected to one end of the telescopic column 7 and the inner bottom wall of the groove 8, respectively. The limiting block 17 is disposed at one end of the telescopic column 7. A plurality of the locking blocks 18 are sequentially disposed on the locking block connecting plate 19. The limiting block 17 is located between two adjacent locking blocks 18. The retraction mechanism is disposed on the inner side wall of the groove 8. The locking block connecting plate 19 is disposed on the retraction mechanism. The sealing ring 15 seals the telescopic joints of the telescopic column 7 and the support plate 5, preventing water from penetrating the groove 8. When the seedling pot 6 is pressed down, the first spring 16 is compressed, and the limiting block 17 moves down, contacting the inclined surfaces of the multiple locking blocks 18, thereby causing the locking blocks 18 to retract. When it stops at the appropriate position, the first spring 16 provides an upward thrust, but this is blocked by the limiting action of the locking blocks 18 and the limiting block 17, thus fixing the telescopic column 7. The seedling tray 6 is positioned between the multiple limiting posts so that the rubber abutment plates 9 on both sides can abut and limit it. When the cultivation is completed or the position of the seedling tray 6 needs to be adjusted, the shrinking mechanism drives the locking block connecting plate 19 to move, thereby causing the multiple locking blocks 18 to shrink. The limiting block 17 disengages from the multiple locking blocks 18, and then the first spring 16 rebounds, driving the telescopic post 7 to reset. At the same time, the abutment on both sides of the seedling tray 6 is removed, and it is no longer installed and fixed, thereby removing the seedling tray 6.

[0031] In addition, the two ends of the plurality of second springs 20 are respectively movably connected to one side of the locking block connecting plate 19 and the inner sidewall of the groove 8. The two electromagnets 21 are respectively disposed on the inner wall of the groove 8 and the locking block connecting plate 19. When the two electromagnets 21 are energized, they generate magnetic force and attract each other, causing the locking block connecting plate 19 to move away from the limiting block 17, and causing the locking block 18 to also move away from the limiting block 17. At the same time, the second springs 20 are compressed. After the telescopic column 7 has rebounded, the electromagnets 21 are de-energized, and then the second springs 20 rebound, driving the locking block connecting plate 19 and the locking block 18 to rebound, so that the telescopic column 7 can continue to press down for limiting use.

[0032] Then, the two fixed cylinders 22 are positioned above the seedling pot 6, the two telescopic rods 23 are slidably connected to the corresponding fixed cylinders 22, the two ends of the two third springs 24 are movably connected to the inner wall of the fixed cylinder 22 and one end of the telescopic rod 23 respectively, the other ends of the two telescopic rods 23 are fixedly connected to the abutting connecting plate 26, the pry block 25 is positioned above the abutting connecting plate 26, and the rubber abutting plate 9 is positioned on one side of the abutting connecting plate 26. The fixed cylinder 22 supports the telescopic rod 23. When the seedling box 1 needs to be installed, first hold the levers 25 on both sides and move them towards the middle so that the telescopic rod 23 enters the fixed cylinder 22, retracting the rubber support plate 9. Then press down on the seedling pot 6 to complete the height adjustment of the seedling pot 6, so that the seedling pot 6 enters between the multiple telescopic columns 7. At this time, the rubber support plate 9 is also located on the outside of the telescopic column 7. Then release the levers 25, and the third spring 24 rebounds, causing the telescopic column 7 to rebound, so that the support connecting plate 26 causes the rubber support plate 9 to rebound. The rubber support plate 9 and the outer wall of the telescopic column 7 are adapted to each other, thereby completing the support and limiting.

[0033] Furthermore, the recycling unit is located inside the seedling box 1. The glass disassembly plate 27 is detachably connected to one side of the seedling box 1, and the glass rotating plate 28 is rotatably connected to one side of the seedling box 1 and located above the glass disassembly plate 27. The support plate 5 has multiple return holes 33, the top of the seedling box 1 has two glass plates 34, each seedling pot 6 has a water-absorbing layer 35 installed on its inner bottom wall, the bottom of the seedling pot 6 has multiple drainage holes 36, the second water pump 29 is located on the inner bottom wall of the seedling box 1, the filter plate 30 is located on one side of the second water pump 29, the inclined plate 31 is located on the inner bottom wall of the seedling box 1, one end of the recycling water pipe 32 is connected to the outlet end of the second water pump 29, and the other end of the recycling water pipe 32 passes through the seedling box 1 and is connected to one side of the water tank 14. When spraying the seedlings of traditional Chinese medicine, excess water flows through the return hole 33 into the area below the support plate 5, then through the inclined plate 31 to the second water pump 29. The filter plate 30 filters out the soil, and then the second water pump 29 pumps the water into the recovery water pipe 32, returning it to the water tank 14 for re-spraying. By disassembling the glass disassembly plate 27, the second water pump 29 and the filter plate 30 inside can be maintained and cleaned. The glass rotating plate 28 can be rotated and opened to allow the seedling box 1 inside to be moved and removed. Simultaneously, relying on the glass disassembly plate 27... The glass rotating plate 28 and the top glass plate 34 allow sunlight to enter, ensuring the growth of the Chinese medicinal herbs. In addition, the water-absorbing layer 35 is made of sponge, which can absorb excess water in the seedling pot 6, preventing the soil from becoming too wet due to excessive watering, which would affect the growth of the Chinese medicinal herbs. At the same time, once the water-absorbing layer 35 reaches saturation, it will no longer absorb water, and the excess water can be discharged from the drainage hole 36. At this time, the water-absorbing layer 35 can also prevent soil from leaking out from the drainage hole 36. Finally, the excess water also reaches the bottom of the support plate 5 through the return hole 33.

[0034] When using the Chinese herbal medicine planting and seedling raising device of this embodiment, when cultivating Chinese herbal medicine seedlings, select seedling pots 6 suitable for different Chinese herbal medicine seedlings, place seedling pots 6 of different sizes above the support plate 5 inside the seedling box 1, and position them on multiple telescopic columns 7. At this time, press down on the seedling pot 6, causing the telescopic columns 7 to move down. Through the cooperation of the limiting block 17 and the locking block 18, the telescopic columns 7 are limited, so that the telescopic columns 7 below the seedling pot 6 move down and are positioned between multiple telescopic columns 7. At this time, the rubber abutment plate 9 rebounds and abuts against the telescopic columns 7, completing the limiting and fixing of the seedling pot 6. Through the above structural setting, the free extension and retraction of multiple telescopic columns 7 can adapt to and fix seedling pots 6 of different sizes, thereby adapting to different kinds of Chinese herbal medicines. It also allows the seedling pot 6 to be installed in a suitable position without needing to be installed in a specific installation area. It can be installed and fixed by choosing a suitable position and abutting, and the spacing between them can be adjusted flexibly and freely, thereby avoiding affecting the growth of the seedlings.

[0035] Please see Figure 7 The present invention also provides a Chinese herbal medicine planting and seedling raising system, which adopts the Chinese herbal medicine planting and seedling raising device described above, and further includes a Chinese herbal medicine seedling loading and unloading device 37, an irrigation water adding device 38, and a filter plate cleaning device 39. The Chinese herbal medicine seedling loading and unloading device 37 is disposed on one side of the seedling box 1, the irrigation water adding device 38 is disposed at one end of the seedling box 1, and the filter plate 39 cleaning unit is disposed on one side of the seedling box 1.

[0036] The seedling feeding and unloading device 37 can load and unload the seedling pots 6 without manual handling. The irrigation water adding device 38 can add water to the water tank 10. The filtration and cleaning device can wash the soil filtered by the filter plate 30 after the glass disassembly plate 27 is removed, so that it can be used continuously.
