Technical Field

[0001] This utility model relates to the field of agricultural irrigation equipment technology, and in particular to a portable drip irrigation regulating device for greenhouse vegetables. Background Technology

[0002] Drip irrigation technology, as a highly efficient and water-saving modern agricultural irrigation method, has been widely used in greenhouse vegetable cultivation. By delivering water and nutrients directly and slowly to the crop roots, it significantly improves water and fertilizer utilization and promotes crop growth. However, currently available drip irrigation systems, especially in greenhouse environments with diverse crop types and short growing cycles, have revealed some structural shortcomings after long-term use.

[0003] Traditional greenhouse drip irrigation systems typically connect drip heads to drip pipes using either threaded tightening or adhesive bonding. While this method provides a secure connection, it is extremely inconvenient when replacing drip heads. For example, adjusting the drip flow rate based on different growth stages of vegetables (seedling stage, growth stage, fruiting stage), or switching to vegetables with different water requirements, becomes a time-consuming and laborious task. It often requires the use of tools such as wrenches, and in cases where the head is bonded, it cannot be replaced without damage. This severely restricts the flexibility and maintenance efficiency of the drip irrigation system.

[0004] Therefore, this utility model proposes a portable drip irrigation adjustment device for greenhouse vegetables to overcome the shortcomings of the prior art. Utility Model Content

[0020] 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.

[0021] Reference Figures 1-4 This utility model provides a portable drip irrigation adjustment device for greenhouse vegetables, which aims to solve the problems of cumbersome drip head replacement and inconvenient irrigation range adjustment in the prior art.

[0022] The portable greenhouse vegetable drip irrigation regulating device includes a water tank 1 as the overall basic frame and a water pump 2 installed on top of the water tank 1. The water tank 1 is used to store drip irrigation water, and the water pump 2 provides a power source for the drip irrigation system. The device also includes a drip irrigation pipe 301 for conveying water flow. The outlet of the water pump 2 is connected to the inlet of the drip irrigation pipe 301 through a hose, forming a basic water supply circuit. The device also includes an regulating component 4 and a drip irrigation component 3. The regulating component 4 is fixedly connected to the side wall of the water tank 1, and the drip irrigation pipe 301 is connected to the water tank 1 through the regulating component 4, so that the regulating component 4 can support and drive the movement of the drip irrigation pipe 301. The drip irrigation component 3 is located at the end of the drip irrigation pipe 301 and is used to install the drip irrigation head 302 and achieve quick replacement.

[0023] The drip irrigation assembly 3 includes a drip head 302, a fixing plate 303, a rotating shaft 304, a torsion spring 305, a connecting pipe 306, a side bracket 307, and a positioning plate 308. The fixing plate 303 serves as a mounting base and is fixedly connected to the outer periphery of the drip irrigation pipe 301. The rotating shaft 304 passes through and is rotatably connected to the inside of the fixing plate 303. The connecting pipe 306 serves as a linkage component, with one end fixedly connected to the rotating shaft 304, allowing the connecting pipe 306 to rotate together with the rotating shaft 304. The torsion spring 305 serves as an elastic element providing reset and locking force, and is sleeved on the outside of the rotating shaft 304, with both ends of the torsion spring 305 abutting against... A torsional preload is always applied to the inner wall of the fixing plate 303 and the outer wall of the connecting pipe 306. The side frame 307, as an extended snap-fit ​​structure, is fixedly connected to the end of the connecting pipe 306 away from the rotating shaft 304. The positioning plate 308 is integrally extended from the end of the side frame 307. The shape and size of the positioning plate 308 are precisely designed to achieve a precise insertion snap-fit ​​with the slot opened on the side wall of the drip head 302. Through the continuous elastic force applied by the torsion spring 305, the positioning plate 308 can be firmly pressed into the slot of the drip head 302, thereby achieving reliable locking of the drip head 302.

[0024] The adjustment assembly 4 includes a back plate 401, a side platform 402, an electric motor 403, a rotating bracket 404, a universal joint 405, and a sliding column 406. The back plate 401 serves as a mounting interface for securely fixing the entire adjustment assembly 4 to the side wall of the water tank 1. The side platform 402 extends from the back plate 401, providing a mounting platform for the electric motor 403, which is mounted on the side platform 402. The output end of the electric motor 403 is connected to the rotating bracket 404 to drive the rotating bracket 404. The rotating frame 404 is connected to the sliding column 406 via a universal joint 405. The presence of the universal joint 405 allows the rotational motion of the rotating frame 404 to be flexibly transmitted to the sliding column 406, even if there is a certain angular deviation between the two. The other end of the sliding column 406 is fixedly connected to the drip irrigation pipe 301. When the electric motor 403 drives the rotating frame 404 to rotate, the entire transmission mechanism will convert the rotational motion into the reciprocating oscillating motion of the drip irrigation pipe 301, thereby realizing the automatic adjustment of the drip irrigation range.

[0025] As a preferred embodiment, to further clarify the internal spatial layout and structural stability of the adjustment component 4, the rotating frame 404 is specifically designed as a ring structure. This ring structure not only has good rigidity itself, but also provides movement space for the internal components. Part of the sliding column 406 is accommodated inside the rotating frame 404, and the universal joint 405 is connected between the inner side of the rotating frame 404 and the sliding column 406. This compact layout effectively shortens the overall size of the adjustment component 4, making the structure more concentrated and stable, while ensuring the flexibility and reliability of motion transmission.

[0026] As another preferred embodiment, in order to enhance the structural strength of the key components of the quick-disassembly part in the drip irrigation component 3 and simplify the manufacturing process, the side frame 307 and the connecting pipe 306 are manufactured in one piece, forming a single integral component. This avoids stress concentration and assembly errors caused by traditional welding or screwing, making the connection between the side frame 307 and the connecting pipe 306 more robust and reliable, and significantly improving the durability and lifespan of the entire snap-fit ​​structure during frequent insertion and removal.

[0027] Working principle: Before use, the operator first selects a drip head 302 with appropriate drip flow rate and drip orifice size based on the type of vegetable, growth stage, and soil conditions. When installing the drip head 302, the operator aligns it with the drip assembly 3 at the end of the drip pipe 301, ensuring the slot on the drip head 302 aligns with the positioning plate 308 extending from the end of the side frame 307, and then pushes it inward. During this pushing process, the drip head 302 pushes the positioning plate 308, thereby causing the side frame 307 and connecting pipe 306 to rotate slightly around the rotating shaft 304. This rotation compresses the torsion spring 305 sleeved on the rotating shaft 304. Once the drip head 302 is pushed into place, the positioning plate 308 falls completely into the slot. At this time, the elastic energy stored in the torsion spring 305 is released, generating a restoring torque that drives the connecting pipe 306 to rotate in the opposite direction, thereby firmly pressing the positioning plate 308 against the side wall of the slot, achieving a fast and reliable locking of the drip head 302.

[0028] When drip irrigation is needed, the water tank 1 filled with water is moved to the target irrigation area inside the greenhouse. The water pump 2 installed on top of the water tank 1 is started, and the water pump 2 begins to work, pumping the water in the water tank 1 into the inlet of the drip irrigation pipe 301 through the connected hose. The water flows inside the drip irrigation pipe 301, eventually reaching and dripping evenly and slowly from the drip nozzles 302, providing precise irrigation to the soil around the vegetable roots.

[0029] If a larger area of ​​irrigation is needed for a row of vegetables, rather than just single-point drip irrigation, the adjustment component 4 can be activated. The operator starts the electric motor 403 mounted on the side platform 402, and the output of the electric motor 403 drives the rotating frame 404 to rotate. Since the rotating frame 404 is connected to the sliding column 406 via the universal joint 405, the rotation of the rotating frame 404 is flexibly converted into the reciprocating swing of the sliding column 406 by the universal joint 405. The sliding column 406 is fixedly connected to the drip irrigation pipe 301; therefore, the swing of the sliding column 406 directly drives the entire drip irrigation pipe 301 and its end drip head 302 to swing smoothly laterally around the adjustment component 4. In this way, the water outlet of the drip head 302 moves back and forth within a fan-shaped area, achieving automatic expansion and uniform coverage of the irrigation range, avoiding the heavy labor of frequently moving the entire device manually.

[0030] When it is necessary to replace the drip irrigation head 302 with a different specification, the operator only needs to hold the drip irrigation head 302 by hand and apply a pulling force opposite to the installation direction to overcome the locking force applied by the torsion spring 305, so that the drip irrigation head 302 can be pulled out from the positioning plate 308, completing the quick disassembly. Then the new drip irrigation head can be installed. The whole replacement process is convenient and efficient, and can flexibly adapt to the complex and ever-changing planting needs in the greenhouse.
