Description

Technical Field

[0001] This utility model provides a distribution pipe assembly, and particularly relates to a drip irrigation solution distribution pipe assembly for chemical regulation and ripening of cotton. Background Technology

[0002] The cotton chemical ripening regulator drip irrigation solution distribution device is a core component of modern agricultural precision irrigation systems. Its function is to mix chemical regulators with water and precisely distribute them into the field drip irrigation pipes according to a set ratio to promote uniform cotton ripening and improve harvesting efficiency. Traditional devices typically use an injection pipe directly connected to multiple storage tanks, with valves controlling the liquid output from each tank. However, this approach suffers from problems such as inflexible liquid level control, easy pipe blockage due to solution sedimentation, and low flow distribution accuracy, making it difficult to meet the precision management needs of modern cotton cultivation.

[0003] The basic structure of existing similar devices includes a main injection pipe connecting multiple parallel storage tanks, with outlet valves at the bottom of the tanks. Some devices also have fixed connecting pipes between the tanks to balance the liquid level. However, these devices have the following significant shortcomings: First, the fixed connection positions between the storage tanks make it impossible to adjust the liquid level according to actual needs, resulting in uneven cotton ripening in different areas due to uneven drug application. Second, the lack of an effective sedimentation and separation mechanism allows solid particles in the solution to easily accumulate in the pipes, causing dripper blockage and increasing maintenance costs. Third, flow regulation relies on a single valve control, making precise proportioning difficult, and frequent valve opening and closing can damage the valve, reducing the device's lifespan. Fourth, the overall structural stability is poor, and long-term operation can easily lead to loosening and leakage at the connections due to vibration. Utility Model Content

[0004] In order to solve the above problems, this application provides a drip irrigation solution distribution pipe assembly for cotton chemical regulation and ripening, which solves the problems of difficulty in uniformly controlling the liquid level, easy clogging due to solution sedimentation, and inaccurate flow distribution in traditional devices.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a drip irrigation solution distribution pipe assembly for cotton chemical regulation and ripening, including an injection pipe, and a plurality of storage tanks are connected to the bottom of the injection pipe;

[0006] The inner walls of the storage tanks on the side that are close to each other are connected by a connecting pipe through a sliding plate. An arc-shaped settling pipe is provided between the connecting pipes. A return tank connected to itself is provided on the bottom side of the middle section of the settling pipe.

[0007] The connecting pipe is fitted with a movable plate, and one end of the movable plate is provided with a threaded rod that passes through it.

[0008] Preferably, the liquid storage tank is fitted with an integrated external frame, and the external frame has a movable groove that corresponds to the width of the movable plate and extends through it.

[0009] Preferably, a base is integrally fixedly connected to the lower part of the outer frame, the threaded rod is inserted into the base, and a smooth limiting rod is fixedly connected to the side of the base away from the threaded rod;

[0010] The threaded rod and the limiting rod pass through the movable groove.

[0011] Preferably, the liquid storage tank has a sliding groove inside with a height greater than that of the sliding plate, and the sliding groove has adjustment ports on both sides that pass through it and correspond to the connecting pipe. The height of the adjustment ports is less than that of the sliding plate.

[0012] Preferably, the sliding plate and the liquid storage tank are sealed together, and the liquid storage tank has an integrated liquid outlet at the bottom, with a built-in regulating valve at the liquid outlet.

[0013] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0014] This device, based on the principles of communicating vessels and liquid level control, achieves precise distribution and regulation of the chemical ripening agent through a mechanical structure. The injection pipe delivers the cotton chemical ripening agent to multiple storage tanks below. These tanks are connected to a return tank via connecting pipes and settling pipes, forming a connected system. Rotating the threaded rod causes a movable plate to slide along a groove in the outer frame, raising and lowering the connecting pipes and sliding plate within the sliding grooves of the storage tanks. This changes the connection position between the tanks, thereby adjusting the highest liquid level in each tank and achieving precise liquid level control. Simultaneously, the arc-shaped settling pipe allows excess liquid to settle and be collected in the return tank, ensuring no waste. A regulating valve is built into the outlet at the bottom of the storage tank. Combined with the sliding plate, the opening and closing of the regulating port further precisely regulates the flow rate of the chemical ripening agent, ensuring that the cotton chemical ripening agent is distributed to the drip irrigation system as needed and evenly, guaranteeing the cotton ripening effect.

[0024] 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.

[0025] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] like Figure 1-4As shown, a drip irrigation solution distribution pipe assembly for chemical regulation and ripening of cotton includes an injection pipe 1, which is connected to multiple storage tanks 2. Each storage tank is connected to a connecting pipe 22 via a sliding plate 21 on its inner wall near each other. An arc-shaped settling pipe 23 is provided between the connecting pipes, with a return tank 24 connected to the bottom of the middle section of the settling pipe. A movable plate 11 is fitted outside the connecting pipe 22, with a threaded rod 12 passing through one end of the movable plate. An integrated external frame 13 is fitted outside the storage tanks 2, with a movable groove 14 corresponding to the movable plate 11 on the frame. A base 15 is fixedly connected below the frame, and the threaded rod 12 is inserted into the base and passes through the movable groove 14 together with a limiting rod 16 on the other side. Inside the storage tank 2, a sliding groove 17 with a height greater than the sliding plate 21 is provided, with adjustment ports 25 on both sides of the groove with a height less than the sliding plate. An outlet 18 with an adjustment valve is integratedly connected below the storage tank.

[0028] In this implementation scheme, the connection structure between the injection pipe 1 and the storage tank 2 forms the main distribution channel. The movable design of the sliding plate 21 and the connecting pipe 22 within the sliding groove 17, combined with the threaded rod 12 driving the movable plate 11 to slide along the movable groove 14, achieves dynamic adjustment of the connection position between the storage tanks. When the threaded rod 12 rotates, the movable plate 11 drives the connecting pipe 22 to rise and fall synchronously, changing the overlapping area of ​​the sliding plate 21 and the adjustment port 25, thereby changing the position of the connecting pipe and thus precisely controlling the upper limit of the liquid level in each storage tank, solving the problem of difficult uniform control of the liquid level in traditional devices. The arc-shaped settling pipe 23 utilizes the principles of fluid mechanics, allowing the liquid in the storage tank that is higher than the height of the connecting pipe to flow into the bottom of the settling pipe and then into the return tank 24. The stable support structure formed by the external frame 13 and the base 15, combined with the guiding effect of the limit rod 16 on the movable plate 11, ensures the stability and reliability of the device operation. The liquid outlet 18 at the bottom of the storage tank 2 has a built-in regulating valve, which, together with the flow regulation of the regulating port 25 by the sliding plate 21, forms a dual control mechanism. This significantly improves the accuracy of liquid distribution and ensures the consistency of the chemical regulation and ripening effect on cotton. The sealed connection design between the sliding plate 21 and the storage tank 2 effectively prevents liquid leakage and extends the service life of the device.

[0029] In practical use, this device needs to be connected to the existing cotton drip irrigation network system. The outlet 18 with a regulating valve at the bottom of the storage tank 2 is connected to the drip irrigation tape and drippers laid in the field via a flexible or rigid pipe, forming a complete pesticide delivery path. To ensure accurate pesticide delivery, it can be used in conjunction with an existing intelligent control system, such as a PLC controller or agricultural IoT terminal. Sensors monitor the liquid level in the storage tank, soil moisture in the field, and the growth status of the cotton in real time. Based on a preset program, the rotation angle of the threaded rod 12 is automatically adjusted to control the lifting and lowering of the connecting pipe 22 and the flow rate of the outlet 18. Regarding material selection, the injection pipe 1, storage tank 2, and connecting pipe 22 can be made of high-strength, corrosion-resistant PVC or PE plastic to ensure that long-term contact with chemical solutions does not easily lead to aging or damage. The seal between the sliding plate 21 and the storage tank 2 is made of fluororubber to enhance sealing performance and chemical resistance. The threaded rod 12 and the limit rod 16 are made of stainless steel to improve mechanical strength and corrosion resistance. The external frame 13 and the base 15 are made of hot-dip galvanized steel to ensure stable support and good outdoor wind and vibration resistance. In addition, to facilitate remote operation and maintenance, position sensors and drive motors can be installed at the movable plate 11 and threaded rod 12 to achieve electric remote control and further improve the automation level and practicality of the device.

[0030] Specifically, during installation, the external frame 13 is first fixed to a flat concrete base using expansion bolts or embedded parts, ensuring the base 15 is level and stable, providing reliable support for the entire device. The top of the injection pipe 1 is connected to the existing liquid supply system, such as storage tanks or mixing devices, via flanges or quick connectors, ensuring stable delivery of the liquid to each storage tank 2. During installation, each storage tank 2 must be vertical, with the sliding groove 17 aligned with the moving direction of the connecting pipe 22. After installation, the sliding plate 21 should be able to slide flexibly within the sliding groove 17 and maintain a good seal. The movable plate 11 is fitted over the connecting pipe 22, allowing it to slide freely along the movable groove 14. The threaded rod 12 passes through the movable plate 11 and engages with the pre-set threaded hole on the base 15. The limiting rod 16 is inserted into the corresponding through hole of the movable plate 11, serving as a guide and preventing deviation.

[0031] When connecting with an existing drip irrigation system, the outlet 18 is connected to the main drip irrigation line in the field via an acid- and alkali-resistant PVC or rubber hose. The connection is sealed with clamps or heat fusion to prevent leakage. The main drip irrigation line further branches into capillary tubes and drippers, forming a complete pesticide delivery network. During operation, operators can manually rotate the threaded rod 12, or have the PLC control system drive the motor to rotate the threaded rod 12, to adjust the position of the movable plate 11, thereby controlling the lifting height of the connecting pipe 22 and the sliding plate 21, and precisely adjusting the liquid level and discharge volume of each storage tank. Simultaneously, existing soil moisture sensors, cotton growth monitoring cameras, and other equipment can be used to collect field data in real time and feed it back to the control system to dynamically optimize the pesticide distribution strategy. The sedimentation pipe 23 and the return tank 24 are periodically cleaned manually by opening the cleaning port. Maintenance only requires disassembling the relevant quick-connect parts, making operation convenient. Throughout the operation of the entire device, in conjunction with the pressure regulating equipment of the existing drip irrigation system, the pesticide is evenly delivered to the cotton plants under appropriate pressure, achieving efficient and precise chemical regulation and ripening operations.

[0032] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
