Description

Technical Field

[0001] This utility model belongs to the field of drip irrigation system for cultivating Polygonatum seedlings, specifically relating to the technology of greenhouse cultivation of Polygonatum seeds. Background Technology

[0002] Polygonatum is a medicinal herb commonly used in daily life. Because wild Polygonatum is expensive and scarce, it is often cultivated indoors in greenhouses from seed. Current methods for cultivating Polygonatum seedlings often involve spraying water and fertilizer-containing water through a sprinkler system to ensure adequate moisture for the seeds and increase survival rates. However, this method suffers from uneven mixing during spraying, especially since large-scale planting is common. When using drip irrigation to spray the soil, nozzles closer to the water source experience higher pressure and flow rates than those further away. Furthermore, for ease of replacement and cost-effectiveness, nozzles are often of the same specifications, which can damage them over time. The high water flow also results in more water being sprayed onto lower sections of the Polygonatum than higher sections, leading to uneven growth and inconsistent survival rates due to over- or under-watering. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a drip irrigation system for cultivating Polygonatum seedlings, which can achieve uniform spraying and uniform mixing of water and fertilizer.

[0004] This utility model includes a drip irrigation system for cultivating Polygonatum sibiricum seedlings, comprising a greenhouse body; multiple sets of support structures are provided inside the greenhouse body; a uniform tank is installed inside the greenhouse body; the uniform tank is equipped with a mixing mechanism, which includes a rotating shaft, stirring blades, a spiral rod, and spiral blades; the rotating shaft is rotatably connected inside the uniform tank, the stirring blades are fixedly connected to the outer wall of the rotating shaft, the spiral rod is fixedly connected to the top of the rotating shaft, and spiral blades are fixedly connected to the outer wall of the spiral rod; a main pipe is detachably connected to the top of the uniform tank, and a spraying mechanism is detachably connected to the outer wall of the main pipe.

[0005] In one embodiment, the spraying mechanism includes a diverter pipe, a uniform distribution box, and a nozzle. The top end of the main pipe is fixedly connected to the diverter pipe via a triangular connector. The end of the diverter pipe away from the triangular connector is fixedly connected to a long pipe via a right-angle connector. The other end of the triangular connector is fixedly connected to the long pipe. The outer wall of the long pipe is connected to a connecting pipe. The bottom end of the connecting pipe is fixedly connected to the uniform distribution box. A valve is rotatably connected inside the uniform distribution box. The bottom end of the uniform distribution box is detachably connected to the nozzle.

[0006] In one embodiment, the interior of the shed is provided with a water tank and a fertilizer tank on both sides of the uniform tank. The water tank and the fertilizer tank are connected to the uniform tank through a pressure boosting pipe, and the two pressure boosting pipes are distributed in a parallelogram.

[0007] In one embodiment, the support mechanism includes multiple sets of opposing concave plates, horizontal plates, and protective frames. Horizontal plates are detachably connected to opposite sides of the concave plates, vertical plates are detachably connected between two concave plates in the same column, and protective frames are detachably connected between the concave plates at both ends.

[0008] In one embodiment, a flow meter is fixedly connected inside the uniform chamber.

[0009] The beneficial effects of this utility model are that an additional uniform tank is designed. When the water in the water tank and the fertilizer-containing water in the fertilizer tank are injected into the uniform tank through the pressurization pipe, the quadrilateral design of the pressurization pipe causes the water flow to exert a unidirectional impact force on the stirring blades, making them rotate naturally. When the rotating shaft rotates, it drives the spiral rod to rotate, making the spiral blades an Archimedes spiral pump. This allows the mixed water to rise with the spiral blades to the main pipe for later irrigation. The water and fertilizer water are mixed in the uniform tank by the stirring blades, which facilitates the uniform effect in the later stage.

[0010] By adding a uniform distribution box, which is equipped with an adjustable valve, the pressure and flow rate of the water entering the nozzles can be controlled, thereby ensuring that the spray volume of multiple nozzles is the same and achieving uniform spraying.

[0017] As attached Figure 1 , 3 As shown, this utility model includes a shed body 1; multiple sets of support mechanisms 2 are provided inside the shed body 1; a uniform tank 3 is installed inside the shed body 1; a water spraying system is connected to the inside of the shed body 1 through the uniform tank 3, the uniform tank 3 provides the water source for later use, and a mixing mechanism 4 is provided inside the uniform tank 3. The mixing mechanism 4 includes a rotating shaft 401, a stirring blade 402, a spiral rod 403, and a spiral blade 404. The rotating shaft 401 is rotatably connected inside the uniform tank 3, and the stirring blade 402 is fixedly connected to the outer wall of the rotating shaft 401. The rotating shaft 401 and the stirring blade 402 are fixedly connected to form a rotating function. When the stirring blade 402 is rotated by the impact of water flow, the rotating shaft 401 is accelerated to rotate, without the need for power supply; the spiral rod 403 is fixedly connected to the top of the rotating shaft 401, and the outer wall of the spiral rod 403 is fixedly connected to... The spiral blade 404, driven by the rotating shaft 401, causes the spiral rod 403 to rotate, resulting in the spiral blade 404 spinning freely and generating suction on the water flow. During use, the liquid in the water tank 7 and fertilizer tank 8 enters the homogenizing tank 3 through the pressurizing pipe 9. Because the pressurizing pipe 9 is designed in parallel and at an angle, the incoming water impacts the stirring blade 402, causing it to rotate. This pushes the stirring blade 402 to rotate, stirring the mixed liquid in the opposite direction. The rotating shaft 401 also drives the spiral rod 403 to rotate, making the spiral blade 404 an Archimedes' screw pump, thus raising the stirred water along with the spiral blade 5 to the main pipe. The pressurizing pipe 9 is a normal water flow pipe; with its built-in pump function inside the water tank 7 and fertilizer tank 8, it quickly discharges water into the homogenizing tank 3, achieving the impact force on the stirring blade 402 and causing it to rotate.

[0018] As attached Figure 2 , 4As shown, this utility model includes a spraying mechanism 6. A diversion pipe 601 is fixedly connected to the top of the main pipe 5 via a triangular connector 604. A long pipe 606 is fixedly connected to the end of the diversion pipe 601 away from the triangular connector 604 via a right-angle connector 605. The other end of the triangular connector 604 is fixedly connected to the long pipe 606. A connecting pipe 607 communicates with the outer wall of the long pipe 606. A uniform distribution box 602 is fixedly connected to the bottom end of the connecting pipe 607. A valve 608 is rotatably connected inside the uniform distribution box 602. A nozzle 603 is detachably connected to the bottom end of the uniform distribution box 602. The design of the triangular connector 604 and the right-angle connector 605 allows for multiple spraying operations. 604 and right-angle connector 605 are commonly used connectors, convenient for use in different applications, thereby improving work efficiency. Valve 608 is an existing water control flow throttle valve, which can achieve fine adjustment of flow by changing the cross-sectional area of ​​the flow channel. The opening and closing of valve 608 affects the incoming water flow and velocity, thereby controlling the uniform spraying effect in the later stage. Since the water pressure in the long pipe 606 near the water source is greater than the pressure far from the water source, the corresponding nozzles 603 are subjected to different pressures. By controlling the water flow through valve 608, the amount of water entering the nozzles 603 can be controlled, allowing the nozzles 603 to spray evenly while protecting them and extending their service life.

[0019] As attached Figure 5 As shown, a horizontal plate 202 is detachably connected to the opposite side of the concave plate 201, a vertical plate 204 is detachably connected between two concave plates 201 in the same column, and a protective frame 203 is detachably connected between the concave plates 201 at both ends. The splicing is completed by multiple sets of support mechanisms 2, and the detachable connection design allows for free adjustment of height and width. The support mechanism 2 can be layered and segmented according to needs, thereby improving the efficiency of cultivation and making better use of the space, thus reducing land loss. A spraying mechanism 6 can be matched with the support mechanism 2, so that the support mechanism 2 and the spray head 603 can be adapted to achieve the utilization target.

[0020] Working principle: During use, the control pumps inside the water tank 7 and fertilizer tank 8 introduce fluid into the booster pipe 9. The liquid injected into the uniform tank 3 is then pushed through the booster pipe 9. The liquid impacts the stirring blades 402, causing them to rotate. This, in turn, rotates the rotating shaft 401. The stirring blades 402 then mix and stir the liquid. The rotating shaft 401 drives the screw rod 403 to rotate. The flow direction of the water is controlled by the screw blades 404 for delivery. By observing the flow rate changes in the flow meter 10, the valve 608 is adjusted to ensure that the flow rate and volume of the water entering the nozzle 603 remain consistent, thus achieving uniform spraying.
