A greenhouse crop irrigation device

Abstract

This utility model provides a greenhouse crop irrigation device, belonging to the field of agricultural planting technology. It includes a support frame, an installation frame slidably connected to the inner side of the support frame, a connecting pipe fixedly connected to the inner side of the installation frame, and an irrigation pipe fixedly connected to the outer side of the connecting pipe. An adjustment component is used to adjust the irrigation height and is connected to the support frame. A water-saving component is used to adaptively close the irrigation outlet and is connected to the irrigation pipe. By setting the adjustment component, pulling the handle drives the slide rod to disengage the locking block from the slot, releasing the installation frame's limit, allowing the irrigation pipe to rise and fall freely. A reset spring automatically locks the height. The operation is simple and efficient, adaptable to the water requirements of different crop growth stages. Specifically, during the seedling stage, the irrigation pipe is lowered to avoid water impact damage, while during the mature stage, the irrigation pipe is raised to cover the entire crop. This solves the problem of uneven irrigation caused by the fixed height of traditional devices, thereby improving irrigation flexibility and crop growth protection.

Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, and in particular to an irrigation device for greenhouse crops. Background Technology

[0002] In greenhouse crop cultivation, the practicality and precision of irrigation devices directly affect crop growth efficiency and water resource utilization.

[0003] Traditional greenhouse irrigation devices generally suffer from two major problems: First, the fixed irrigation height makes it difficult to adapt to the needs of crops throughout their entire growth cycle. During the seedling stage, the excessively high position of the irrigation pipe can easily cause water impact damage to the seedlings, while during the mature stage, the insufficient height makes it difficult for the upper part of the plant to receive water evenly. Moreover, the adjustment process often relies on disassembly using tools or complex mechanical structures, making operation cumbersome, inefficient, and unable to quickly respond to the dynamic water demand changes of crop growth. Second, the irrigation water output control lacks adaptive design and relies heavily on manual valve closing. This can easily lead to continuous leakage of residual water in the pipes after the water flow stops due to operational delays, resulting in water waste. At the same time, traditional devices cannot dynamically adjust the water output according to the water flow rate, making it difficult to achieve precise water supply for different crops and different growth stages. This increases irrigation costs and may also affect crop quality and yield due to excessive or insufficient water supply. Therefore, this application provides a greenhouse crop irrigation device to meet these needs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an irrigation device for greenhouse crops, which solves the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A greenhouse crop irrigation device includes a support frame, an installation frame slidably connected to the inner side of the support frame, a connecting pipe fixedly connected to the inner side of the installation frame, an irrigation pipe fixedly connected to the outer side of the connecting pipe, an adjustment component for adjusting the irrigation height, the adjustment component being connected to the support frame, and a water-saving component for adaptively closing the irrigation outlet, the water-saving component being connected to the irrigation pipe.

[0007] Optionally, the adjustment assembly includes a slide rod slidably connected to the side of the support frame, one end of the slide rod being fixedly connected to a connecting plate, multiple sets of slots being equidistantly provided on one side of the mounting frame, a limit hole being provided on the outer side of the support frame, and a locking block being fixedly connected to the side of the connecting plate near the support frame, and the locking block engaging with the inner side of the slot.

[0008] Optionally, a pull handle is fixedly connected to the outside of the connecting plate, and a limiting post is fixedly connected to the side of the connecting plate near the locking block, with the limiting post inserted into the inner side of the limiting hole.

[0009] Optionally, a return spring A is provided on one side of the connecting plate, and the return spring A is sleeved on the outside of the slide rod.

[0010] Optionally, the water-saving component includes a spray pipe fixedly connected to the bottom of the irrigation pipe, with multiple spray holes on the outer side of the spray pipe, a fixing frame fixedly connected to the inner side of the spray pipe, a limit rod slidably connected to the inner side of the fixing frame, and a sealing sleeve fixedly connected to the bottom of the limit rod.

[0011] Optionally, a return spring B is provided inside the sealing sleeve, and the return spring B is sleeved on the outside of the limiting rod.

[0012] Optionally, a water tank is provided on the outside of the support frame, a water supply pipe is fixedly connected to the outside of the water tank, a water pump is fixedly connected to the inside of the water supply pipe, a motor is fixedly connected to the back of the water pump, and a flexible hose is fixedly connected between the top of the water pump and the connecting pipe.

[0013] Beneficial effects:

[0014] In the above solution, by setting an adjustment component, pulling the handle drives the slide rod to move the locking block out of the slot. After the installation frame limit is released, the irrigation pipe can be raised and lowered freely. The reset spring automatically locks the height. The operation is simple and efficient, and it can be adapted to the water requirements of crops at different growth stages. That is, the irrigation pipe is lowered during the seedling stage to avoid water flow impact damage, and the irrigation pipe is raised during the maturity stage to cover the entire crop. This solves the problem of uneven irrigation caused by the fixed height of traditional devices, thereby improving irrigation flexibility and crop growth protection.

[0015] By setting up water-saving components, the outlet can be automatically opened and closed by balancing the water pressure and the spring force: when the water flows, it pushes the sealing sleeve to open the spray hole, and when the water stops, the spring automatically resets and seals, preventing residual water leakage. At the same time, the opening range of the sealing sleeve is automatically adjusted according to the water flow, so as to achieve precise irrigation. Unlike traditional valve control, this can reduce water waste and improve the water-saving efficiency and operational reliability of the irrigation system. Attached Figure Description

[0023] 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.

[0024] like Figure 1 and Figure 2As shown, an embodiment of this utility model provides a greenhouse crop irrigation device, including a support frame 1, an mounting frame 2 slidably connected to the inner side of the support frame 1, a connecting pipe 4 fixedly connected to the inner side of the mounting frame 2, an irrigation pipe 5 fixedly connected to the outer side of the connecting pipe 4, an adjusting component 3 for adjusting the irrigation height, the adjusting component 3 being connected to the support frame 1, a water-saving component 6 for adaptively closing the irrigation outlet, the water-saving component 6 being connected to the irrigation pipe 5, a water tank 7 provided on the outer side of the support frame 1, a water supply pipe 8 fixedly connected to the outer side of the water tank 7, a water pump 10 fixedly connected to the inner side of the water supply pipe 8, a motor 9 fixedly connected to the back of the water pump 10, and a flexible hose 11 fixedly connected between the top of the water pump 10 and the connecting pipe 4. Please provide a greenhouse crop irrigation device that allows for flexible adjustment of the irrigation pipe height via adjustable component 3, adapting to the irrigation needs of crops at different growth stages. It can meet the short-distance irrigation needs of seedlings and low-growing crops, as well as adapt to high-level irrigation scenarios for mature, tall crops, improving the flexibility and precision of greenhouse irrigation and reducing the impact of unsuitable irrigation height on crop growth. Simultaneously, the water-saving component 6 controls the irrigation water output, avoiding the problem of residual water leakage caused by valves not closing in time, thus reducing water waste. Furthermore, the water flow can be directly adjusted by regulating the opening of the sealing sleeve through impact force, indirectly controlling the water output from the spray nozzles, achieving flexible control of irrigation volume and improving the water-saving efficiency and precision of greenhouse irrigation.

[0025] In this embodiment, as Figures 3 to 4As shown, the adjusting assembly 3 includes a slide rod 301 slidably connected to the side of the support frame 1. One end of the slide rod 301 is fixedly connected to a connecting plate 302. A slot 304 is equidistantly provided on one side of the mounting bracket 2. A limiting hole 308 is provided on the outer side of the support frame 1. A locking block 306 is fixedly connected to the side of the connecting plate 302 near the support frame 1, and the locking block 306 engages with the inner side of the slot 304. A handle 303 is fixedly connected to the outer side of the connecting plate 302. A limiting post 307 is fixedly connected to the side of the connecting plate 302 near the locking block 306, and the limiting post 307 is inserted into the inner side of the limiting hole 308. A return spring A305 is provided on one side of the connecting plate 302, and the return spring A305 is sleeved on the outer side of the slide rod 301. In use, the handle 303 is first pulled, causing the handle 303 to move the slide rod 301 on the inner side of the connecting plate 302 towards the support frame 1. The frame 1 moves outward, causing the locking block 306 and the limiting post 307 to disengage from the connection between the locking slot 304 and the limiting hole 308. This allows the mounting frame 2 to be lifted, which in turn adjusts the height of the irrigation pipe 5 on the outside of the connecting pipe 4. Then, the pull handle 303 is released, and the elastic force of the return spring A305 causes the locking block 306 and the limiting post 307 to reset, thus achieving flexible adjustment of the irrigation pipe height to meet the irrigation needs of crops at different growth stages. This not only meets the short-distance irrigation needs of seedlings and low-growing crops but also adapts to the high-level irrigation scenarios of mature, tall crops, improving the flexibility and precision of greenhouse irrigation and reducing the impact of unsuitable irrigation height on crop growth. Afterward, the motor 9 is turned on to drive the water pump 10 to deliver the water inside the water tank 7 through the water supply pipe 8 and the hose 11 to the inside of the connecting pipe 4 and the irrigation pipe 5, thereby irrigating the greenhouse crops.

[0026] In this embodiment, as Figures 5 to 6As shown, the water-saving component 6 includes a spray pipe 601 fixedly connected to the bottom of the irrigation pipe 5. Multiple spray holes 603 are opened on the outer side of the spray pipe 601. A fixing frame 604 is fixedly connected to the inner side of the spray pipe 601. A limit rod 605 is slidably connected to the inner side of the fixing frame 604. A sealing sleeve 602 is fixedly connected to the bottom of the limit rod 605. A return spring B606 is provided inside the sealing sleeve 602, and the return spring B606 is sleeved on the outer side of the limit rod 605. When water flows through the irrigation pipe 5 and towards the spray pipe 601, the water impacts the sealing sleeve 602, causing the limit rod 605 to slide downwards along the inner side of the fixing frame 604, thus causing the sealing sleeve... The seal between the 602 and the bottom of the spray pipe 601 is no longer sealed, allowing water to flow through the spray hole 603 to irrigate the crops. When the water flow stops, the sealing sleeve 602 loses its impact force, and the elastic force of the return spring B606 re-seales the sealing sleeve 602 and the bottom of the spray pipe 601, preventing water from flowing out of the spray hole 603. This avoids the problem of residual water leakage caused by valves not closing in time in traditional irrigation devices, reducing water waste. At the same time, the water flow can be directly adjusted by the impact force to regulate the opening of the sealing sleeve, indirectly controlling the water output of the spray hole, achieving flexible control of irrigation volume, and improving the water-saving efficiency and accuracy of greenhouse irrigation.

[0027] The working principle of the technical solution provided by this utility model is as follows: In use, first pull the handle 303, causing the handle 303 to move the sliding rod 301 on the inner side of the connecting plate 302 towards the outer side of the support frame 1. This causes the locking block 306 and the limiting post 307 to disengage from the slot 304 and the limiting hole 308, thereby lifting the mounting frame 2 and adjusting the height of the irrigation pipe 5 on the outer side of the connecting pipe 4. Then, release the handle 303, and the elastic force of the return spring A305 causes the locking block 306 and the limiting post 307 to reset, thus achieving flexible adjustment of the irrigation pipe height to adapt to the irrigation needs of crops at different growth stages. It can meet the short-distance irrigation needs of low-growing crops in the seedling stage and also adapt to the high-level irrigation scenarios of tall crops in the mature stage, improving the flexibility and accuracy of greenhouse irrigation and reducing the impact of unsuitable irrigation height on crop growth. Afterwards, turn on the motor 9 to drive the water pump 10 to pump water from the inside of the water tank 7 through the water supply pipe 8 and the flexible hose. 11. Water is delivered to the inner side of the connecting pipe 4 and the irrigation pipe 5 to irrigate the greenhouse crops. When the water flows through the irrigation pipe 5 to the spray pipe 601, the water impacts the sealing sleeve 602, causing the limiting rod 605 to slide downward along the inner side of the fixing frame 604. This loosens the seal between the sealing sleeve 602 and the bottom of the spray pipe 601, allowing water to flow through the spray hole 603 to irrigate the crops. When the water flow stops, the sealing sleeve 602 loses its impact force, and the elastic force of the return spring B606 re-seales the sealing sleeve 602 and the bottom of the spray pipe 601, preventing water from flowing out of the spray hole 603. This avoids the problem of residual water leakage caused by the valve not closing in time in traditional irrigation devices, reducing water waste. At the same time, the water flow can be directly adjusted by the impact force to regulate the opening of the sealing sleeve, indirectly controlling the water output of the spray hole, achieving flexible control of the irrigation amount, and improving the water-saving efficiency and accuracy of greenhouse irrigation.
