Description

Technical Field

[0001] This utility model relates to the field of Angelica sinensis cultivation technology, specifically to a soilless seedling cultivation device for Angelica sinensis. Background Technology

[0002] Soilless cultivation of Angelica sinensis refers to an agricultural cultivation technique that does not use traditional natural soil, but instead utilizes nutrient solutions, water, or specially formulated artificial substrates to provide Angelica sinensis plants with water, nutrients, and oxygen, enabling them to complete their entire or part of their life cycle. Soilless seedling cultivation equipment for Angelica sinensis refers to equipment specifically designed for germinating Angelica sinensis seeds and cultivating them into robust seedlings in a non-soil environment.

[0003] Application No. 202223346736.3 discloses a soilless seedling cultivation device for Angelica sinensis. This patent includes an upper seedling trough and a lower seedling trough that work together. Ventilation holes are evenly distributed on the periphery of the lower seedling trough, ensuring good ventilation and minimizing the growth of harmful bacteria. An inner baffle is fixedly connected to the bottom wall of the lower seedling trough, forming a nutrient solution storage tank together with the bottom wall. The height of the inner baffle is lower than the height of the outer wall of the lower seedling trough. Nutrient solution is added to the storage tank, maintaining the solution level below the height of the inner baffle to prevent overflow. Angelica sinensis seeds are placed in the seedling tube, and a seedling sponge column provides nutrients for germination. Soilless seedling cultivation is achieved through the nutrient solution, further protecting the seeds from bacterial damage and effectively improving the germination rate.

[0004] While the aforementioned comparative documents can ensure that the nutrient solution level does not exceed the height of the inner enclosure to prevent nutrient solution overflow, during the hydroponic cultivation of Angelica sinensis seedlings, the nutrient solution level in the storage tank will drop due to plant absorption and transpiration. The aforementioned patent maintains the nutrient solution level by having operators add nutrient solution to the storage tank. This method of adding nutrient solution relies on manual judgment and operation, which can easily lead to problems such as improper timing of replenishment and incorrect calculation of the replenishment amount, thereby affecting the hydroponic cultivation of Angelica sinensis. Utility Model Content

[0005] The purpose of this invention is to provide a soilless cultivation and seedling raising device for Angelica sinensis to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a soilless cultivation seedling device for Angelica sinensis, comprising a storage tank and a frame, wherein the frame is connected to the top of the outer wall of the storage tank, and a seedling tray is provided in the middle of the top of the storage tank; fixing plates are welded to both sides of the inner wall of the storage tank, and a limiting seat is connected inside the fixing plate; one side of the outer wall of the limiting seat is fixedly connected to the seedling tray, and the limiting seat is inserted into the fixing plate to fix the seedling tray; Support frames are connected to both sides of the top end of the storage tank, a storage box is connected to the middle of the top end of the support frames, liquid discharge pipes are fixedly connected to both sides of the bottom end of the storage box, and the liquid discharge pipes are configured to导出 the nutrient solution stored inside the storage box; A floating frame is slidably connected to the inner wall of the storage tank, fixed columns are connected to both sides of the top end of the floating frame, movable columns are slidably connected to the outer wall of the fixed columns, a base is fixedly connected to the top end of the movable columns, a limiting cylinder is fixedly connected to the middle of the top end of the base, the inner wall of the limiting cylinder is in sliding connection with the liquid discharge pipe, the liquid level height in the storage tank is the height where the floating frame is located, the movement of the floating frame drives the base to move synchronously, so that the nutrient solution in the storage box flows into the storage tank, and the liquid level height of the nutrient solution in the storage tank is maintained.

[0007] The liquid level is directly sensed through the buoyancy of the floating frame, and once the liquid level starts to drop, the fluid replacement process is started almost synchronously, thereby controlling the liquid level fluctuation within a very small range.

[0008] Preferably, a fixing groove is opened inside the fixing plate, into which the bottom of the limiting seat can extend, the limiting seat has a "T"-shaped structure, and a drainage pipe is installed in the middle of the bottom end of the storage tank.

[0009] By moving the limiting seat downward to insert it into the fixing plate, the limiting of the seedling raising tray can be completed.

[0010] Preferably, limiting pins are fixedly connected to both sides of the bottom end of the support frame, limiting holes are opened on both sides of the top end of the support frame, and the limiting pins can extend into the limiting holes to fix the support frame.

[0011] By moving the support frame downward to insert the limiting pins into the top end of the storage tank, the limiting of the support frame can be completed.

[0012] Preferably, fixing cavities are opened on both sides inside the support frame, limiting strips are connected inside the fixing cavities, and the top ends of the limiting strips are fixedly connected with the bottom end of the storage box.

[0013] By moving the storage box downward to insert the limiting strips at the bottom of the storage box into the top of the support frame, the limiting of the storage box can be completed.

[0014] Preferably, a liquid delivery port is opened on one side of the bottom end of the base, the base has a "square"-shaped structure, and drainage grooves with equal included angles are opened at the bottom end of the limiting cylinder.

[0015] When the base moves downward and is disconnected from the bottom of the liquid discharge pipe, the base cancels the blocking of the liquid discharge pipe, and at this time the liquid discharge pipe导出 the nutrient solution stored inside the storage box.

[0016] Preferably, both the fixed column and the movable column have a "square"-shaped structure, a fixing pin is threadedly connected to one side of the bottom end of the movable column, a movable hole corresponding to the fixing pin is opened on one side of the outer wall of the movable column, and the movable holes are distributed at equal intervals.

[0017] Once the movable column has moved to the designated height, the fixing pin is rotated and inserted into the corresponding fixing hole on the outer wall of the fixed column. This limits the movable column and prevents it from moving further, thus facilitating the adjustment of the total length of the fixed column and the movable column by the staff.

[0018] Preferably, the limiting cylinder, drainage groove, base, movable column and fixed column constitute a liquid delivery channel.

[0019] Nutrient solution is fed from the storage tank into the storage tank through the delivery channel, causing the liquid level in the storage tank to rise.

[0020] As can be seen from the above, the soilless cultivation and seedling raising device for Angelica sinensis provided by this utility model has the following beneficial effects.

[0021] 1. The liquid level is directly sensed by the buoyancy of the float frame. Once the liquid level begins to drop, the replenishment process starts almost simultaneously. This eliminates the need for operators to constantly monitor the liquid level or frequently add nutrient solution, thus controlling liquid level fluctuations within a very small range, reducing labor intensity and labor costs. Furthermore, by adjusting the total length of the fixed column and the movable column, different target liquid levels can be preset, improving the flexibility of use.

[0022] 2. By modularizing components such as storage tanks, seedling trays, and storage boxes, operators can quickly assemble them. When a component is damaged, it can be quickly disassembled and replaced, thereby improving maintenance efficiency and reducing equipment downtime. Attached Figure Description

[0025] 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.

[0026] Please see Figures 1-13 This utility model provides a technical solution: a soilless cultivation seedling device for Angelica sinensis, including a storage tank 1 and a frame 2. The frame 2 is connected to the top of the outer wall of the storage tank 1, and a seedling tray 5 is provided in the middle of the top of the storage tank 1. Fixing plates 3 are welded to both sides of the inner wall of the storage tank 1, and a limiting seat 4 is connected inside the fixing plate 3. One side of the outer wall of the limiting seat 4 is fixedly connected to the seedling tray 5. The limiting seat 4 is inserted into the fixing plate 3 to fix the seedling tray 5. The top two sides of the storage tank 1 are connected to support frames 6, and the top middle of the support frame 6 is connected to a storage box 8. The bottom two sides of the storage box 8 are fixedly connected to drain pipes 10, which are used to drain the nutrient solution stored inside the storage box 8. A float frame 11 is slidably connected to the inner wall of the storage tank 1, and fixed columns 12 are connected to the top two sides of the float frame 11. A movable column 13 is slidably connected to the outer wall of the fixed column 12, and a base 14 is fixedly connected to the top of the movable column 13. A limiting cylinder 15 is fixedly connected to the middle of the top of the base 14, and the inner wall of the limiting cylinder 15 is slidably connected to the drain pipe 10. The liquid level in the storage tank 1 is the height of the float frame 11. The movement of the float frame 11 will drive the base 14 to move synchronously, so that the nutrient solution inside the storage tank 8 flows to the storage tank 1, maintaining the liquid level of the nutrient solution in the storage tank 1. A liquid feeding opening is provided on one side of the bottom end of the base 14, the base 14 has a square-frame-shaped structure, and drainage grooves 16 at equal included angles are provided on the bottom end of the limiting cylinder 15; both the fixed column 12 and the movable column 13 have a square-frame-shaped structure, a fixing pin 17 is threadedly connected to one side of the bottom end of the movable column 13, movable holes corresponding to the fixing pin 17 are provided on one side of the outer wall of the movable column 13, and the movable holes are distributed at equal intervals; the limiting cylinder 15, the drainage grooves 16, the base 14, the movable column 13 and the fixed column 12 form a liquid feeding channel.

[0027] In specific implementation, the storage tank 1 is placed at a designated position in advance through the frame 2, then a certain amount of nutrient solution is poured into the storage tank 1, and then the seedling tray 5 is placed inside the storage tank 1. At this time, the root system of Angelica sinensis is in contact with the nutrient solution inside the storage tank 1, and with the cooperation of the light control equipment in the greenhouse, it is ensured that the seedlings obtain the optimal light cycle and intensity; the temperature control equipment maintains a suitable temperature for germination and growth; the humidity control equipment controls air humidity to prevent diseases; thus, in a non-soil environment, Angelica sinensis seeds are germinated and cultivated into robust seedlings.

[0028] Refer to Figure 3 , Figure 5 and Figure 7 , the floating frame 11 is located inside the storage tank 1, at this time the liquid level in the storage tank 1 is the height of the floating frame 11. When the floating frame 11 moves downward due to plant absorption and transpiration, the floating frame 11 drives the fixed column 12 to move downward together, then the downward movement of the fixed column 12 drives the movable column 13 to move downward, and the downward movement of the movable column 13 drives the base 14 to move together; Refer to Figure 8 , Figure 9 and Figure 10 , when the base 14 moves downward and is disconnected from the bottom of the drainage pipe 10, it cancels the blocking of the drainage pipe 10, at this time the drainage pipe 10导出 the nutrient solution stored inside the storage tank 8, the nutrient solution first passes through the drainage grooves 16 at the bottom of the limiting cylinder 15, then sequentially passes through the base 14 - the movable column 13 - the fixed column 12, and finally flows into the storage tank 1 from the edge of the floating frame 11, so that the liquid level in the storage tank 1 rises; At this time, as the liquid level rises, the floating frame 11 moves upward together, which in turn causes the base 14 to move upward until the liquid level rises to the specified height, at this time the base 14 contacts the bottom of the drainage pipe 10 and blocks it, preventing the nutrient solution from continuing to be discharged; By rotating the fixing pin 17 to disconnect from the fixed column 12, the limiting of the movable column 13 can be canceled. At this time, the movable column 13 is moved vertically, so that the total length of the movable column 13 and the fixed column 12 changes, until the movable column 13 is moved to the specified height, then the fixing pin 17 is rotated to insert into the corresponding fixing hole on the outer wall of the fixed column 12, thereby limiting the movable column 13 to prevent it from continuing to move, which is convenient for staff to adjust the total length of the fixed column 12 and the movable column 13; When the liquid level in the storage tank 1 needs to be low, the total length of the fixed column 12 and the movable column 13 increases; when the liquid level in the storage tank 1 needs to be high, the total length of the fixed column 12 and the movable column 13 decreases.

[0029] Furthermore, it eliminates the need for operators to constantly monitor the liquid level and frequently add nutrient solution manually. The liquid level is directly sensed by the buoyancy of the float frame 11. Once the liquid level begins to drop, the replenishment process starts almost simultaneously, thereby controlling the liquid level fluctuation within a very small range, reducing labor intensity and labor costs. Moreover, by adjusting the total length of the fixed column 12 and the movable column 13, different target liquid levels can be preset, improving the flexibility of use.

[0030] See Figure 4 , Figure 5 , Figure 9 , Figure 11 and Figure 12 The fixed plate 3 has a fixed groove inside, into which the bottom of the limiting seat 4 can extend. The limiting seat 4 has a "T" shaped structure. A drain pipe is installed in the middle of the bottom end of the storage tank 1. Limiting pins 7 are fixedly connected to both sides of the bottom end of the support frame 6. Limiting holes are opened on both sides of the top end of the support frame 6, into which the limiting pins 7 can extend to fix the support frame 6. Fixed cavities are opened on both sides inside the support frame 6. Limiting strips 9 are connected inside the fixed cavities. The top end of the limiting strips 9 is fixedly connected to the bottom end of the storage box 8.

[0031] In practice, the staff only needs to move the storage tank 1 to the top of the frame 2 to complete the positioning of the storage tank 1; by moving the limiting seat 4 down to insert it into the fixed plate 3, the seedling tray 5 can be positioned; by moving the support frame 6 down to insert the limiting pin 7 into the top of the storage tank 1, the support frame 6 can be positioned; by moving the storage box 8 down to insert the limiting strip 9 at the bottom into the top of the support frame 6, the storage box 8 can be positioned. Furthermore, by modularizing components such as storage tank 1, seedling tray 5, and storage box 8, operators can quickly assemble them, and when a component is damaged, it can be quickly disassembled and replaced, thereby improving maintenance efficiency and reducing equipment downtime.

[0032] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
