Description

Technical Field

[0001] This utility model relates to the field of drip irrigation technology for crops, specifically to a drip irrigation structure for greenhouse planting of crops. Background Technology

[0002] Drip irrigation delivers water precisely to the roots of crops. In greenhouses, different crops have different water requirements, and drip irrigation systems can accurately provide the appropriate amount of water according to the needs of each crop. For crops with shallow root systems, drip irrigation can directly supply water to the shallow root zone, avoiding the negative effects of too much or too little water on crop growth. At the same time, compared to traditional flood irrigation, drip irrigation reduces water evaporation and loss. In greenhouse environments, the temperature is relatively high and the air humidity is high; if flood irrigation is used, water evaporation will be even more severe. Drip irrigation, however, slowly drips water into the soil, allowing the water to be directly absorbed by the soil and retained around the roots, increasing water use efficiency to about 90%-95%, greatly saving water resources. Furthermore, the high humidity environment in greenhouses easily leads to pests and diseases. Flood irrigation increases air and soil humidity, providing favorable conditions for the growth of pathogens and pests. Because drip irrigation supplies water locally to the roots, it does not cause a significant increase in overall greenhouse humidity, effectively reducing air humidity and decreasing the incidence of diseases such as downy mildew and powdery mildew. Moreover, because the soil moisture is relatively stable, it is not conducive to the reproduction of some pests that prefer a humid environment; therefore, drip irrigation equipment is required in the process of drip irrigation of crops.

[0003] For example, the prior art application number CN202021803534.5 discloses a drip irrigation structure for greenhouse planting of crops, including a crossbeam and multiple drip irrigation mechanisms. The multiple drip irrigation mechanisms are respectively installed on the crossbeam. Each drip irrigation mechanism includes a drip irrigation pipe, multiple drip irrigation heads, a first installation component and a second installation component. The two ends of the drip irrigation pipe are respectively installed on the crossbeam through the first installation component and the second installation component. Several through holes are evenly distributed on the lower end face of the drip irrigation pipe. A threaded connector is installed at each through hole. The drip irrigation head is threadedly connected to the threaded connector.

[0004] The aforementioned existing technology, as learned through practical use, mainly uses multiple fixed drip irrigation heads distributed in a ring to irrigate crops. However, the fixed drip irrigation heads limit the irrigation range and cannot flexibly adjust the irrigation range. If the range is too large, it will result in water waste and inaccurate irrigation; if the range is too small, it will result in insufficient irrigation, thus reducing the effective range of drip irrigation. Therefore, based on actual usage, we have improved the aforementioned existing technology. Utility Model Content

[0005] To address the issues that drip irrigation can cause limitations in its coverage area, making it difficult to flexibly adjust the irrigation range, resulting in water waste and inaccurate drip irrigation if the coverage area is too large, and insufficient drip irrigation if the coverage area is too small, thus reducing the effective range of drip irrigation, this utility model aims to provide a drip irrigation structure for greenhouse planting of crops.

[0006] To achieve this technical objective, the present invention provides a drip irrigation structure for greenhouse crop cultivation, comprising a base, a square tube fixed to the upper end of the base, and at least three sets of adjustment devices on the front side of the square tube; the adjustment devices include a first arc-shaped tube and a second arc-shaped tube, the lower ends of the first arc-shaped tube and the second arc-shaped tube being fixedly connected to drip irrigation heads, and a bidirectional screw being provided between the first arc-shaped tube and the second arc-shaped tube for driving the first arc-shaped tube, the second arc-shaped tube, and the drip irrigation heads to move.

[0007] Preferably, the base has an integrally formed ear block on both the left and right ends, and a circular rod is integrally formed between the two ear blocks, with one end of the circular rod passing through the first arc tube and the second arc tube.

[0008] Preferably, a water inlet pipe is fixed to the rear side of the square pipe for supplying water to the square pipe, and a three-way flexible hose is fixed and connected between the upper end of the square pipe and the first and second arc-shaped pipes.

[0009] Preferably, the rear ends of the first and second arc-shaped tubes are threaded to a bidirectional lead screw, and a circular hole is provided inside the rear ends of the first and second arc-shaped tubes, with the circular hole slidably disposed with the circular rod.

[0010] Preferably, both the first and second arc-shaped tubes have through holes at their upper ends, and the through holes are threaded with threaded plugs.

[0011] Preferably, baffles are fixed to the outer sides of both the No. 1 arc tube and the No. 2 arc tube by bolts; Beneficial effects

[0012] This invention allows for a flexible adjustment of the distance between the first and second arc-shaped tubes. Rotating the bidirectional screw clockwise decreases the distance between them, while rotating it counter-clockwise increases the distance. This means the distance between the first and second arc-shaped tubes can be flexibly changed by rotating the bidirectional screw, enabling the drip head to adapt to different drip irrigation needs and significantly increasing the effective range of drip irrigation.

[0013] The No. 1 and No. 2 arc tubes can be used in fertilizer storage tanks. During use, fertilizer solution can be injected into the No. 1 and No. 2 arc tubes through the through hole. After mixing with irrigation water, it will drip out from the drip head, which can realize irrigation and fertilization at the same time, which is beneficial to crop growth.

[0014] Furthermore, an opening is provided between the front ends of the No. 1 and No. 2 arc-shaped tubes, allowing for flexible movement and adjustment. This facilitates the placement of the No. 1 and No. 2 arc-shaped tubes around crops of different diameters, increasing adaptability. Attached Figure Description

A square tube 2 is fixed to the upper end of the base 1. At least three sets of adjustment devices 3 are provided on the front side of the square tube 2. The adjustment device 3 includes a first arc-shaped tube 31 and a second arc-shaped tube 32. The lower ends of the first arc-shaped tube 31 and the second arc-shaped tube 32 are fixedly connected to drip irrigation heads 33. A bidirectional screw 34 is provided between the first arc-shaped tube 31 and the second arc-shaped tube 32 to drive the first arc-shaped tube 31, the second arc-shaped tube 32 and the drip irrigation heads 33 to move.

[0023] refer to Figure 1 and Figure 2 The base 1 has integrated lugs on both its left and right ends, with a circular rod 4 integrally installed between the two lugs. One end of the circular rod 4 passes through the first arc-shaped tube 31 and the second arc-shaped tube 32. This allows each set of adjustment devices 3 to be manually pulled to flexibly change its position. A water inlet pipe 5 is fixed to the rear side of the square tube 2 for supplying water to it. A three-way flexible hose 35 is fixed and connected between the upper end of the square tube 2 and the first and second arc-shaped tubes 31 and 32, ensuring that it does not affect the movement of the adjustment devices 3. The rear ends of the first and second arc-shaped tubes 31 and 32 are threaded onto a two-way screw 34. Circular holes 39 are opened inside the rear ends of the first and second arc-shaped tubes 31 and 32, and these holes slidably engage with the circular rod 4.

[0024] refer to Figure 2 Both the first arc tube 31 and the second arc tube 32 have through holes 37 at their upper ends. The through holes 37 are threaded with threaded plugs 38 for sealing.

[0025] refer to Figure 2 Both the outer sides of the No. 1 arc pipe 31 and the No. 2 arc pipe 32 are fixed with baffles 36 by bolts to provide shade for the drip irrigation area of ​​crops and reduce water evaporation.

[0026] Working principle: After the water inlet pipe 5 is connected to the external water pump, water can be injected into the drip irrigation head 33 to achieve the purpose of drip irrigation; during use, the distance between the first arc pipe 31 and the second arc pipe 32 can be adjusted by rotating the bidirectional screw 34, so that the drip irrigation head 33 can be moved as the first arc pipe 31 and the second arc pipe 32 move, thereby changing the drip irrigation range.

[0027] When the bidirectional screw 34 is rotated clockwise, the distance between the first arc-shaped tube 31 and the second arc-shaped tube 32 decreases; when the bidirectional screw 34 is rotated counterclockwise, the distance between the first arc-shaped tube 31 and the second arc-shaped tube 32 increases. This allows the distance between the first arc-shaped tube 31 and the second arc-shaped tube 32 to be flexibly adjusted by rotating the bidirectional screw 34, enabling the drip irrigation head 33 to adapt flexibly to different drip irrigation ranges and greatly increasing the effective range of drip irrigation.

[0028] Meanwhile, the No. 1 arc tube 31 and the No. 2 arc tube 32 can be used as fertilizer storage boxes. During use, fertilizer solution can be injected into the No. 1 arc tube 31 and the No. 2 arc tube 32 through the through hole 37. After mixing with irrigation water, it drips out from the drip head 33, which can realize irrigation and fertilization at the same time, which is beneficial to crop growth.

[0029] Furthermore, an opening is provided between the front ends of the first arc tube 31 and the second arc tube 32, allowing for flexible movement and adjustment. This facilitates the fitting of the first arc tube 31 and the second arc tube 32 around crops of different diameters, increasing adaptability.
