Description

Technical Field

[0001] This utility model relates to the field of Chinese medicinal herb cultivation technology, specifically to a Chinese medicinal herb seedling greenhouse with a precision drip irrigation system. Background Technology

[0002] In the field of Chinese medicinal herb cultivation, irrigation management during the seedling stage directly affects the survival rate and growth quality of seedlings; traditional drip irrigation systems in Chinese medicinal herb seedling greenhouses generally suffer from low automation and insufficient precision control capabilities.

[0003] A utility model patent with announcement number CN222193132U discloses a fertilization drip irrigation device for greenhouses, comprising: a mixing component, a drip irrigation component, and a monitoring component. The mixing component is fixedly connected to at least two connecting pipes, and a first control valve is fixedly installed on each connecting pipe. Each connecting pipe is used to connect to a water source and a fertilizer supply box, respectively. One side of the mixing component is fixedly connected to the drip irrigation component. The monitoring component is used to monitor the growth status of crops and soil moisture. The monitoring component, drip irrigation component, mixing component, and first control valve are all electrically connected to a controller.

[0004] Although this utility model can achieve the effect of controlling the mixing ratio of different fertilizers and water, as well as the precise dosage of pesticides, the drawbacks of its fixed installation method for drip irrigation pipes have gradually become apparent in actual seedling cultivation scenarios. Due to the uncontrollable variability in the planting position of seedlings during the seedling cultivation process, it is difficult to ensure that each seedling is within the optimal irrigation coverage range of the fixed drip irrigation pipe. This makes it difficult for the existing fixed drip irrigation pipes to flexibly adapt to the changing plant layout requirements in the seedling cultivation process. It has obvious deficiencies in the timeliness and effectiveness of precise irrigation and cannot fully meet the actual application needs of complex seedling cultivation operations. Utility Model Content

[0005] The purpose of this invention is to provide a seedling greenhouse for Chinese medicinal herbs with a precision drip irrigation system, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A seedling greenhouse for Chinese medicinal herbs equipped with a precision drip irrigation system includes a greenhouse body, wherein several base plates are fixed to the ground inside the greenhouse body, and further includes:

[0008] A water storage mechanism for storing medicine, the water storage mechanism including a water tank disposed on the base plate, and a water outlet pipe installed at the bottom of the water tank;

[0009] A drip irrigation mechanism for drip irrigation of pesticides includes two mounting plates fixed to the bottom of a water storage tank. The two mounting plates are located at the left and right ends of a water outlet pipe, respectively. A water passage box is fixed to the front side of both mounting plates, and the water passage box is connected to the water outlet pipe. A bracket is fixed to the end of the front side of the mounting plate away from the water outlet pipe. A support column is fixed between the two brackets. Several movable blocks are slidably connected to the support column. A drip irrigation head is fixed to the bottom of each movable block. The drip irrigation head and the water passage box are connected to each other via a flexible tube. U-shaped blocks are fixed to the left and right ends of the top of each movable block. Movable columns are slidably connected to the two horizontal plates of each U-block. A pressure plate is fixed to the bottom of each movable column. An anti-slip pad is adhered to the bottom of the pressure plate and is tightly fitted to the support column.

[0010] A control mechanism for controlling the drip irrigation speed includes a baffle that is slidably connected inside the water storage tank. The control mechanism adjusts the water inlet area of ​​the water outlet pipe through the baffle to control the drip irrigation speed.

[0011] Preferably, a collar is fixed to the outer wall of the movable column near the lower horizontal plate of the U-shaped block, and a spring sleeved on the outside of the movable column is installed between the collar and the higher horizontal plate of the U-shaped block.

[0012] Preferably, a pull plate is fixed to the top of both movable columns, and a pull ring is fixed at the center of the top surface of the pull plate;

[0013] These two features, through the elastic cooperation of the collar and spring, allow the pressure plate to drive the anti-slip pad to fit tightly against the support column, achieving automatic locking after the movable block is adjusted, preventing the drip head from shifting; at the same time, the pull plate and pull ring provide a force application point, allowing the operator to easily pull the pull ring to move the movable column upward, releasing the pressure of the anti-slip pad and flexibly adjusting the position of the drip head.

[0014] Preferably, a hydraulic cylinder is fixed at the center of the top surface of the substrate, and the top end of the telescopic end of the hydraulic cylinder is fixed to the bottom of the water storage tank.

[0015] This feature uses a hydraulic cylinder to extend and retract, causing the water tank to move the drip irrigation head up and down, adapting to the height changes of the medicinal herb seedlings at different growth stages and ensuring that the drip irrigation head maintains the optimal irrigation distance from the seedlings.

[0016] Preferably, the top of the water storage tank is fixed with a cover, and a number of feed hoppers are regularly installed on the cover;

[0017] Preferably, the system also includes a stirring mechanism, which includes a stirring motor fixed at the center of the top surface of the cover, and the output shaft of the stirring motor extends into the water storage tank and is fixed with a rotating shaft. Several stirring blades are regularly fixed on the outer wall of the rotating shaft.

[0018] These two features include sealing the water tank with a lid to prevent the evaporation of the medicine or the entry of impurities, and regularly distributed feed hoppers that provide multiple feeding ports so that various medicines or fertilizers can be added at the same time and evenly. The stirring motor drives the rotating shaft to rotate the stirring blades, which makes the medicine or fertilizer solution in the water tank fully mixed, ensuring that the seedlings absorb nutrients evenly.

[0019] Preferably, the control mechanism further includes a horizontal plate fixed to the inner wall of the water storage tank near the bottom end, and two limiting posts are symmetrically fixed between the bottom surface of the horizontal plate and the bottom surface of the water storage tank, and both limiting posts are slidably connected to the baffle.

[0020] Preferably, the control mechanism further includes a mounting block fixed to the inner side wall of the water storage tank near the top. A control motor is fixed to the bottom surface of the mounting block. An internally threaded sleeve is fixed to the output shaft of the control motor. A lead screw is internally threaded to the internally threaded sleeve. A control column is fixed to the bottom end of the lead screw. The bottom end of the control column passes through the horizontal plate and is fixedly connected to the baffle.

[0021] These two settings control the screw drive of the internal threaded sleeve and the lead screw by controlling the motor to move the baffle up and down precisely, adjust the water inlet area of ​​the water outlet pipe, and thus control the drip irrigation speed.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] 1. This utility model features a sliding movable block and drip head. The position of the drip head can be manually adjusted via a pull ring and a pull plate. The combination of a spring and an anti-slip pad achieves positioning and fixation, breaking the limitations of traditional fixed drip irrigation pipes. The coverage of the drip head can be dynamically adjusted according to the seedling planting location, ensuring that each seedling is in the optimal irrigation area. This solves the problem of uneven irrigation caused by changes in plant layout during the seedling stage, and improves the timeliness and effectiveness of irrigation.

[0024] 2. This utility model, by setting a control mechanism to adjust the water inlet area of ​​the water outlet pipe through a baffle, can precisely adjust the drip irrigation speed according to the water requirements of different growth stages of Chinese medicinal seedlings, avoiding root rot caused by excessive water or growth affected by insufficient water, and improving the survival rate and growth quality of seedlings.

[0039] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0040] Please see Figures 1-6 The present invention provides the following technical solution:

[0041] A seedling greenhouse for Chinese medicinal herbs equipped with a precision drip irrigation system includes a greenhouse body 100, several base plates 200 fixed to the ground inside the greenhouse body 100, and also includes:

[0042] A water storage mechanism 400 for storing medicine includes a water storage tank 401 disposed on a base plate 200, and a water outlet pipe 404 is installed at the bottom of the water storage tank 401.

[0043] A drip irrigation mechanism 600 for drip irrigation of pesticides includes two mounting plates 601 fixed to the bottom of a water storage tank 401. The two mounting plates 601 are located at the left and right ends of a water outlet pipe 404, respectively. A water passage box 602 is fixed to the front side of both mounting plates 601, and the water passage box 602 is connected to the water outlet pipe 404. A bracket 603 is fixed to the front side of the mounting plate 601 away from the water outlet pipe 404. A support column 604 is fixed between the two brackets 603. Several movable blocks 605 are slidably connected to the support column 604. A drip irrigation head 606 is fixed to the bottom of each movable block 605. The irrigation head 606 and the water box 602 are connected to each other by a flexible hose 607. The top left and right ends of the movable block 605 are fixed with U-shaped blocks 608. The two horizontal plates of the U-shaped block 608 are slidably connected to the movable column 609. The bottom of the movable column 609 is fixed with a pressure plate 612. The bottom of the pressure plate 612 is attached with an anti-slip pad 613. The anti-slip pad 613 is tightly attached to the support column 604, which can adjust the position of each drip irrigation head 606. The coverage of the drip irrigation head can be dynamically adjusted according to the seedling planting position to ensure that each seedling is in the optimal irrigation area and solve the problem of uneven irrigation caused by changes in plant layout during the seedling stage.

[0044] A control mechanism 700 for controlling drip irrigation speed includes a baffle 703 slidably connected inside a water storage tank 401. The control mechanism 700 adjusts the water inlet area of ​​the water outlet pipe 404 through the baffle 703 to control the drip irrigation speed, which can accurately control the drip irrigation speed and improve the timeliness and effectiveness of irrigation.

[0045] In this embodiment, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 A collar 610 is fixed to the outer wall of the movable column 609 near the lower horizontal plate of the U-shaped block 608. A spring 611 is installed between the collar 610 and the higher horizontal plate of the U-shaped block 608, which is sleeved on the movable column 609. The elasticity of the spring 611 can cause the pressure plate 612 to drive the anti-slip pad 613 to fit tightly against the support column 604. When the movable block 605 is adjusted to the target position, the spring 611 applies downward pressure through the collar 610 to ensure that the drip head 606 is fixed and does not shift, thereby improving the structural stability.

[0046] Specifically, a pull plate 614 is fixed to the top of both movable columns 609. A pull ring 615 is fixed at the center of the top surface of the pull plate 614. The pull ring 615 and the pull plate 614 provide a convenient point of force application. The operator can lift the pull ring 615 to move the movable column 609 upward, release the pressure of the anti-slip pad 613 on the support column 604, and thus easily slide the movable block 605 to realize the quick adjustment of the position of the drip head 606, making the operation user-friendly.

[0047] In this embodiment, please refer to Figure 3 A hydraulic cylinder 300 is fixed at the center of the top surface of the substrate 200. The top end of the extension end of the hydraulic cylinder 300 is fixed to the bottom of the water storage tank 401. The hydraulic cylinder 300 can drive the water storage tank 401 to move up and down, thereby adjusting the vertical height of the drip irrigation head 606 to adapt to the height changes of the Chinese medicinal seedlings at different growth stages, ensuring that the drip irrigation head 606 maintains the optimal irrigation distance from the seedlings, and avoiding uneven irrigation or water splashing caused by a fixed height.

[0048] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 3 The top of the water storage tank 401 is fixed with a cover 402, and several feed hoppers 403 are regularly installed on the cover 402. The cover 402 can seal the water storage tank 401 to prevent the evaporation of the medicine or the entry of impurities. The feed hoppers 403 provide multiple feeding ports, which facilitates the simultaneous addition of multiple medicines or fertilizers. The regularly distributed design can ensure that the materials are evenly fed into the water storage tank 401, thereby improving the operating efficiency.

[0049] Specifically, it also includes a stirring mechanism 500, which includes a stirring motor 503 fixed at the center of the top surface of the cover 402. The output shaft of the stirring motor 503 extends into the water storage tank 401 and is fixed with a rotating shaft 501. Several stirring blades 502 are regularly fixed on the outer wall of the rotating shaft 501. The stirring motor 503 drives the rotating shaft 501 to rotate the stirring blades 502, stirring the medicine or fertilizer solution in the water storage tank 401 to prevent solute precipitation, ensure uniform solution concentration, thereby stabilizing the liquid composition of the drip irrigation, ensuring the balanced absorption of nutrients by the seedlings, and improving the seedling quality.

[0050] In this embodiment, please refer to Figure 3 and Figure 6The control mechanism 700 also includes a horizontal plate 701 fixed to the inner wall of the water storage tank 401 near the bottom. Two limiting posts 702 are symmetrically fixed between the bottom surface of the horizontal plate 701 and the bottom surface of the water storage tank 401. Both limiting posts 702 are slidably connected to the baffle 703. The limiting posts 702 cooperate with the horizontal plate 701 to provide guidance and limit for the up and down movement of the baffle 703, so as to prevent the baffle 703 from shifting or tilting during the adjustment process, and ensure that the baffle 703 accurately corresponds to the inlet of the water outlet pipe 404, thereby stabilizing the drip irrigation speed and improving the adjustment accuracy.

[0051] Specifically, the control mechanism 700 also includes a mounting block 704 fixed to the inner wall of the water storage tank 401 near the top. A control motor 705 is fixed to the bottom surface of the mounting block 704. An internal threaded sleeve 706 is fixed to the output shaft of the control motor 705. A lead screw 707 is internally threaded to the internal threaded sleeve 706. A control column 708 is fixed to the bottom end of the lead screw 707. The bottom end of the control column 708 passes through the horizontal plate 701 and is fixedly connected to the baffle 703. The control motor 705 drives the baffle 703 to move up and down through the threaded transmission between the internal threaded sleeve 706 and the lead screw 707, which can precisely adjust the water inlet area of ​​the water outlet pipe 404 and realize the automated and precise control of the drip irrigation speed.

[0052] Finally, it should be noted that the hydraulic cylinder 300, stirring motor 503, and control motor 705 involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0053] When using the medicinal herb seedling greenhouse with a precision drip irrigation system, water and the required medicine and fertilizer are injected into the water storage tank 401 through the feed hopper 403 on the cover 402. Note that different materials are evenly added from different feed hoppers. Start the stirring motor 503, and the rotating shaft 501 and stirring blade 502 rotate. The stirring time is set according to the required solution concentration to prevent solute precipitation.

[0054] Pulling the ring 615 drives the pull plate 614, causing the movable column 609 to move upward and compress the spring 611. At the same time, the pressure plate 612 and the anti-slip pad 613 disengage from the support column 604, and the movable block 605 slides along the support column 604, moving the drip head 606 above the corresponding seedling. Releasing the ring 615 causes the spring 611 to return to its original position, pushing the anti-slip pad 613 to press tightly against the support column 604 and fix its position.

[0055] The control motor 705 is started, and through the threaded transmission between the internal threaded sleeve 706 and the lead screw 707, the baffle 703 is driven to move up and down. When the baffle 703 moves up, the water inlet area of ​​the water outlet pipe 404 increases, and the drip irrigation speed increases. When the baffle moves down, the water inlet area decreases, and the drip irrigation speed decreases, thus achieving precise water control. The medicine flows from the water storage tank 401 through the water outlet pipe 404, the water box 602, and the hose 607 to the drip irrigation head 606 by its own gravity, thus achieving natural drip irrigation.

[0056] When the seedlings grow to different heights, the hydraulic cylinder 300 is activated to drive the water storage tank 401 to move up and down, and the vertical height of the drip irrigation head 606 is adjusted synchronously.

[0057] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
