Description

Technical Field

[0001] This utility model specifically relates to a seedling cultivation device for Chinese medicinal materials, belonging to the field of Chinese medicinal material seedling cultivation technology. Background Technology

[0002] In the cultivation of Chinese medicinal herbs, seedling cultivation is a crucial foundational step. Traditionally, seedling cultivation for medicinal herbs mostly utilizes open-air seedbeds or simple greenhouses, a method with numerous drawbacks. Firstly, open-air seedbeds are highly susceptible to natural environmental factors; uneven rainfall can lead to waterlogging in some areas, affecting root respiration and even causing root rot and death. During droughts, timely and even irrigation is difficult, hindering seedling growth and development. Secondly, seedling cultivation in simple greenhouses typically involves manually moving seedling trays, which is labor-intensive, inefficient, and makes precise management difficult.

[0003] Therefore, in order to improve the timeliness of seedling cultivation, specialized cultivation devices are often used to cultivate seedlings. In existing cultivation devices, seedling pots are mostly vertically fixed on seedling racks. Due to the shading of the upper seedling pots, the lower seedlings cannot obtain sufficient and uniform light. Especially in the multi-layer three-dimensional cultivation mode, the lower seedlings are in a light-deficient environment for a long time, and photosynthesis is severely inhibited, resulting in slow seedling growth, weak stems, yellowing leaves, and even poor development due to the inability to accumulate enough photosynthetic products, which reduces the overall quality and survival rate of seedlings. At the same time, during irrigation, excess irrigation water cannot be effectively recycled, which not only wastes water resources but also easily leads to water accumulation in the seedbed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a seedling cultivation device for Chinese medicinal herbs. By changing the tilt angle of the seedling rack, the seedlings in the lower layer can receive sufficient sunlight, improving the overall quality and survival rate of the seedlings. At the same time, it can recycle irrigation water, saving water resources and preventing water accumulation in the seedbed.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a seedling cultivation device for Chinese medicinal materials, including a movable base, on which upright plates are symmetrically fixedly connected to the surface of the movable base, and a seedling cultivation component is arranged between the two upright plates. The seedling cultivation component includes a seedling rack, a placement groove and a seedling pot. The seedling rack is installed between the two upright plates, and the surface of the seedling rack is provided with placement grooves at equal intervals, with a seedling pot placed in each placement groove.

[0006] Two uprights are equipped with irrigation components located above the seedling rack. The irrigation components include water supply pipes, nozzles, and fixing plates. Fixing plates are fixedly connected to the surfaces of the two uprights at the same height. A water supply pipe is fixedly connected between the two fixing plates. Multiple nozzles are fixedly connected to the surface of each water supply pipe at equal intervals.

[0007] Preferably, in order to prevent water accumulation in the seedling trays from causing root rot in the seedlings and to create a good growth environment for the seedling roots, a water collection trough is provided at the lower part of the inside of the seedling rack, a through groove is provided between the placement trough and the water collection trough, and water permeable holes are evenly provided on the bottom surface of the seedling trays.

[0008] Preferably, in order to prevent the soil in the seedling pot from flowing into the water collection tank with the water flow during the cultivation process, and to prevent the soil in the seedling pot from being lost, a filter screen is placed inside the seedling pot.

[0009] Preferably, in order to adjust the angle of the seedling rack so that the seedlings can receive better light at different growth stages and improve photosynthetic efficiency, each of the seedling racks is fixedly connected to two rotating shafts at both ends. The two rotating shafts are rotatably connected to two upright plates respectively. One of the rotating shafts passes through the upright plate and extends to the outside of the upright plate, and is fixedly connected to a sprocket set on the outside of the upright plate. A chain is meshed between the two sprockets.

[0010] Preferably, in order to accurately adjust the tilt angle of the seedling rack and make the operation more convenient and faster, a gear is fixedly sleeved on the surface of one of the rotating shafts, a toothed plate is meshed on the surface of the gear, an electric push rod is fixedly connected to the bottom surface of the toothed plate, the electric push rod is fixedly installed on the surface of the movable base, and a T-shaped positioning post is fixedly connected to the surface of the upright plate, the T-shaped positioning post being slidably inserted into the T-shaped groove opened on the surface of the toothed plate.

[0011] Preferably, in order to facilitate irrigation of seedlings, a water tank and a water pump are fixedly connected to the surface of the movable base. The water inlet end of the water pump is fixedly connected to an inlet pipe that extends into the interior of the water tank. The water outlet end of the water pump is fixedly connected to an outlet pipe that is connected to two water delivery pipes.

[0012] Preferably, in order to collect excess irrigation water into a water tank and then reuse the recycled water for irrigation, thereby realizing the recycling of water resources, a corrugated hose is fixedly connected between the two seedling racks, and the corrugated hose is connected to the water collection trough. A return pipe is fixedly connected between the lower seedling rack and the water tank, and the return pipe is connected to both the water tank and the water collection trough.

[0013] Preferably, in order to effectively avoid the nozzles obstructing the seedling growth space and ensure that the seedlings are not disturbed by external structures from the early stage of cultivation to maturity, so as to ensure that they can grow freely in an unobstructed environment and avoid growth deformities or uneven lighting caused by physical obstruction, the nozzles are set at a 30° angle on the outside of the seedling rack.

[0014] The beneficial effects of this utility model are as follows: This medicinal herb seedling cultivation device, through the cooperation of a rotating shaft, sprocket, chain, gear, and toothed plate with an electric push rod, can flexibly adjust the angle of the seedling rack, allowing the seedlings to obtain the optimal light angle and area, effectively preventing the upper seedling rack from blocking the lower seedlings, ensuring uniform light exposure for seedlings on all layers, promoting efficient photosynthesis, and significantly improving seedling growth quality and developmental uniformity; by setting the nozzles at a 30° angle on the outside of the seedling rack, combined with the adjustable angle of the seedling rack, the water flow can accurately cover the seedlings, reducing... Minimal water waste and splashing; the irrigation system, consisting of a water pump, water tank, and water delivery pipes, enables automated and uniform irrigation, ensuring that each seedling receives adequate water, thus improving irrigation efficiency and cultivation results. Simultaneously, the drainage holes at the bottom of the seedling pots, the water collection troughs and through-channels within the seedling racks, along with corrugated hoses and return pipes, promptly collect excess irrigation water and return it to the water tank for recycling. This not only avoids water waste and reduces cultivation costs but also prevents root rot, pests, and diseases caused by waterlogging in the cultivation area, achieving green and environmentally friendly sustainable cultivation.

[0023] 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.

[0024] Please see Figures 1-7 As shown, a seedling cultivation device for Chinese medicinal materials includes a movable base 1. The movable base 1 is characterized by having upright plates 2 symmetrically fixedly connected to its surface. A seedling cultivation component 3 is arranged between the two upright plates 2. The seedling cultivation component 3 includes a seedling rack 31, a placement groove 33, and a seedling pot 36. The seedling rack 31 is installed between the two upright plates 2. The surface of the seedling rack 31 is provided with placement grooves 33 at equal intervals. Each placement groove 33 contains a seedling pot 36.

[0025] Two uprights 2 are positioned above the seedling rack 31 and are equipped with irrigation components 4. Irrigation components 4 include water delivery pipes 45, nozzles 46 and fixing plates 47. Fixing plates 47 are fixedly connected to the surfaces of the two uprights 2 at the same height. Water delivery pipes 45 are fixedly connected between the two fixing plates 47. Multiple nozzles 46 are fixedly connected at equal intervals to the surface of each water delivery pipe 45.

[0026] Specifically, a water collection trough 35 is provided at the lower part of the inside of the seedling rack 31, a through groove 34 is provided between the placement groove 33 and the water collection trough 35, and water permeable holes 37 are evenly provided on the bottom surface of the seedling pot 36.

[0027] During irrigation or natural rainfall, excess water in the seedling tray 36 flows out through the evenly distributed permeable holes 37 on the bottom surface, and collects in the water collection trough 35 located at the lower part of the seedling rack 31 through the through groove 34 between the placement trough 33 and the water collection trough 35. The permeable holes 37, the through groove 34, and the water collection trough 35 form a continuous drainage system, which can quickly drain excess water from the seedling tray 36, prevent the seedling roots from rotting due to prolonged soaking, and ensure the healthy growth of the seedlings. The water collected in the water collection trough 35 can be recycled, realizing water conservation and reducing cultivation costs. At the same time, it effectively prevents the growth of bacteria and insects in the cultivation area due to water accumulation, reduces the risk of pests and diseases, and creates a good growth environment for the seedlings.

[0028] Specifically, a filter screen 38 is placed inside the seedling tray 36.

[0029] A filter screen 38 is placed inside the seedling tray 36. Its specific function and effect are as follows:

[0030] During irrigation or water infiltration, the water flow carries soil particles, root debris, and other impurities from the seedling pot 36 downwards through the permeable holes 37. At this time, the filter screen 38 placed in the seedling pot 36 intercepts these impurities, allowing only water to pass through. The intercepted impurities remain above the filter screen 38, while the filtered water flows into the collection tank 35 through the through groove 34. The filter screen 38 can maintain the stability of the soil structure in the seedling pot 36, prevent soil from being lost with the water flow, and ensure that the growth environment of the seedling roots is not damaged.

[0031] Specifically, each seedling rack 31 has a rotating shaft 32 fixedly connected to both ends. The two rotating shafts 32 are rotatably connected to the two upright plates 2 respectively. One of the rotating shafts 32 passes through the upright plate 2 and extends to the outside of the upright plate 2, and is fixedly connected to the sprocket 39 set on the outside of the upright plate 2. A chain 310 is meshed between the two sprockets 39.

[0032] A gear 311 is fixedly sleeved on the surface of one of the rotating shafts 32. A toothed plate 312 is meshed on the surface of the gear 311. An electric push rod 314 is fixedly connected to the bottom surface of the toothed plate 312. The electric push rod 314 is fixedly installed on the surface of the movable base 1. A T-shaped positioning post 313 is fixedly connected to the surface of the upright plate 2. The T-shaped positioning post 313 is slidably inserted into the T-shaped groove opened on the surface of the toothed plate 312.

[0033] The electric push rod 314 serves as the power source. After activation, it extends and retracts, driving the toothed plate 312, which is fixedly connected to it, to move linearly along the direction of the T-shaped positioning post 313. When the toothed plate 312 moves, the gear 311 meshing with it rotates accordingly. Since the gear 311 is fixedly sleeved on the rotating shaft 32, it drives the rotating shaft 32 to rotate. Because the rotating shafts 32 at both ends of each seedling rack 31 are interconnected through sprockets 39 and chains 310, when one rotating shaft 32 rotates, it will synchronously drive other rotating shafts 32 through the chain 310, causing multiple seedling racks 31 to rotate simultaneously. The staff can precisely adjust the tilt angle of the seedling rack 31 by controlling the extension and retraction of the electric push rod 314. Through the above transmission structure, the angle of the seedling rack 31 can be quickly adjusted according to the light direction at different times and the light requirements of the seedling growth stage, ensuring that the seedlings on each layer can obtain sufficient and uniform light, effectively avoiding the upper seedling rack from blocking the lower layer, significantly improving the photosynthetic efficiency of the seedlings, and promoting their healthy growth.

[0034] Specifically, a water tank 41 and a water pump 43 are fixedly connected to the surface of the movable base 1. The water inlet end of the water pump 43 is fixedly connected to a water inlet pipe 42, which extends into the interior of the water tank 41. The water outlet end of the water pump 43 is fixedly connected to a water outlet pipe 44, which is connected to two water supply pipes 45 respectively.

[0035] A corrugated hose 48 is fixedly connected between the two seedling racks 31. The corrugated hose 48 is connected to the water collection tank 35. A return pipe 49 is fixedly connected between the seedling rack 31 below and the water tank 41. The return pipe 49 is connected to the water tank 41 and the water collection tank 35 respectively.

[0036] Water tank 41 serves as a water storage unit, pre-filled with irrigation water. After water pump 43 starts, water is drawn from water tank 41 through inlet pipe 42, then transported to water delivery pipe 45 through outlet pipe 44, and finally evenly sprayed into seedling pots 36 by nozzle 46, completing irrigation. When there is too much water in seedling pots 36, excess water flows through permeable holes 37, through through-channel trough 34 into water collection trough 35, and then through corrugated hose 48, collecting layer by layer to the water collection trough 35 of the bottom seedling rack, and finally returning to water tank 41 through return pipe 49, forming a complete closed loop of "water supply-irrigation-drainage-recycling-reuse", ensuring that each seedling receives an equal amount of water, promoting uniform growth; at the same time, excess water is quickly drained to prevent water accumulation in seedling pots 36, which can lead to root rot, and reduce the incidence of fungal diseases (such as damping-off) caused by a humid environment.

[0037] Specifically, the nozzle 46 is set at a 30° angle on the outside of the seedling rack 31.

[0038] The nozzle 46 is externally positioned and tilted, maintaining a distance of 3-5cm from the seedling rack 31, to avoid its own structure blocking the seedlings' light or growth space, and is especially suitable for the seedlings to receive continuous and uniform light after they grow taller (such as when the plant height exceeds 10cm).

[0039] Working principle: When using this seedling device, the staff will insert the seedling trays 36 containing Chinese medicinal herb seeds or early seedlings into the placement slots 33 on the surface of the seedling rack 31. The stable support structure formed by the movable base 1 and the upright plate 2 provides a stable cultivation foundation for the seedlings. At the same time, the movable base 1 facilitates the flexible transfer of the device between different cultivation sites to adapt to diverse environmental needs. At this stage, the seedling rack 31 is in an initial horizontal or slightly tilted state, which is convenient for placement and operation.

[0040] After placement, daily light management begins. Based on the daily light direction and the light requirements of the seedlings at different growth stages, the electric push rod 314 is activated. The electric push rod 314 extends and retracts, causing the toothed plate 312 to move linearly along the T-shaped positioning column 313. The toothed plate 312 meshes with the gear 311, causing the rotating shaft 32 to rotate. Since the rotating shaft 32 is connected to the chain 310 via the sprocket 39, multiple seedling racks 31 rotate synchronously, tilting away from the nozzle 46 to avoid the nozzle 46 blocking the light. By precisely adjusting the angle of the seedling racks 31, it is ensured that the seedlings in each layer receive sufficient and uniform light, significantly improving photosynthetic efficiency, promoting healthy seedling growth, and solving the problem of uneven light distribution in traditional devices.

[0041] When the seedlings need irrigation, first restart the electric push rod 314 to adjust the angle of the seedling rack 31 in the opposite direction so that it tilts towards the nozzle 46, ensuring that the 30° tilt spray range of the nozzle 46 can fully cover the seedling pot 36. Then start the water pump 43 to draw water from the water tank 41 through the water inlet pipe 42, and deliver it to the water delivery pipe 45 through the water outlet pipe 44. Finally, the nozzle 46 sprays the water evenly onto the roots of the seedlings in the seedling pot 36. The tilt angle design of the nozzle 46, combined with the tilt of the seedling rack 31, allows the water flow to accurately cover the seedlings, reducing water waste and splashing.

[0042] After irrigation, excess water in the seedling pot 36 flows out through the permeable holes 37 on the bottom surface, flows into the water collection trough 35 inside the seedling rack 31 through the through groove 34, and then collects layer by layer through the corrugated hose 48 to the water collection trough 35 of the bottom seedling rack. Finally, it returns to the water tank 41 through the return pipe 49, realizing the recycling of water resources, reducing cultivation costs, and eliminating the problem of water waste in traditional devices. At the same time, timely drainage of excess water avoids the root rot problem caused by water accumulation in the seedling pot 36 and reduces fungal diseases caused by humid environment.

[0043] Once the seedlings have matured, the seedling trays 36 can be removed from the placement troughs 33, completing the seedling cultivation process. The movable base 1 facilitates moving the entire device to other locations or quickly replacing the seedling trays 36 with a new batch to begin the next round of cultivation, thereby improving cultivation efficiency and shortening the cultivation cycle.
