Description

Technical Field

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

[0002] In modern greenhouse agriculture, automatic irrigation systems are key equipment for ensuring healthy crop growth and achieving high-efficiency production. Their precise and efficient irrigation function provides suitable water conditions for various crops in greenhouses, thereby promoting robust growth and improving the yield and quality of agricultural products.

[0003] A search revealed Chinese patent CN217694592U, which discloses an automatic irrigation and spraying device for greenhouses, relating to the field of greenhouse technology. The device includes a greenhouse body with two fixed plates fixedly installed on its inner wall. An irrigation mechanism is provided on the lower surface of each fixed plate, and one of the fixed plates has a first groove on its lower surface. This patented device primarily relies on nozzles installed at the top of the greenhouse to spray water downwards, thereby irrigating indoor crops. This design achieves a certain degree of automated irrigation and has advantages in saving labor costs compared to traditional manual irrigation methods.

[0004] Based on the above research and combined with extensive existing technology studies, it has been found that most automatic greenhouse irrigation systems currently employ the traditional method of top-mounted sprinklers spraying water downwards. However, this seemingly conventional irrigation mode has revealed numerous drawbacks in practical applications. The problems are particularly pronounced when dealing with shrubs or other crops with dense growth and complex foliage. The intertwining branches and overlapping leaves severely obstruct the downward-spraying water flow. This results in uneven water distribution to all parts of the crops, leaving some areas without sufficient moisture. Prolonged exposure to this uneven irrigation environment significantly impacts crop growth, leading to uneven individual growth and inhibiting overall growth, thus directly reducing irrigation efficiency and failing to meet the crops' need for uniform and sufficient water, ultimately affecting the yield and quality of agricultural products. Utility Model Content

[0005] To address the aforementioned technical problems, this invention proposes an automatic greenhouse irrigation device. The irrigation nozzle mechanism comprises a main irrigation pipe, a conveying pipe arranged in a ring and rotating upwards, and atomizing nozzles detachably connected to the conveying pipe. This invention achieves the effect of omnidirectional spraying irrigation of greenhouse crops from bottom to top, solving the problems of uneven irrigation and low efficiency caused by plant branches and leaves blocking the water flow in traditional irrigation methods.

[0006] The technical solution to achieve the purpose of this utility model is: an automatic greenhouse irrigation device, including a horizontal pipe, a hook is provided at the top of the horizontal pipe to suspend the horizontal pipe from the indoor ceiling, one end of the horizontal pipe is connected to a water inlet pipe, and irrigation water is transported to the horizontal pipe by an external water pump, and also includes;

[0007] The drain pipes are evenly distributed along the length of the horizontal pipe and have their lower outlets pointing vertically downwards.

[0008] An irrigation nozzle mechanism is provided, which is located directly below the drain pipe of the corresponding inlet pipe, and the top of the irrigation nozzle mechanism is connected to the bottom of the corresponding drain pipe via a flexible hose.

[0009] A support assembly is movably connected to the bottom of the irrigation nozzle mechanism, and the irrigation nozzle mechanism is inserted into the soil surface via the support assembly.

[0010] The irrigation nozzle mechanism includes a vertical irrigation main pipe and a delivery pipe that is distributed in a ring-shaped upward rotation on the outer cylinder of the irrigation main pipe. Each delivery pipe can be detachably connected to an atomizing nozzle.

[0011] In some embodiments, the atomizing nozzle includes a nozzle body and a connecting pipe connected to the bottom of the nozzle body. The outer cylinder of the connecting pipe has an external thread, and the inner opening of the delivery pipe has an internal thread. The atomizing nozzle is threadedly connected to the delivery pipe through the connecting pipe.

[0012] In some embodiments, the support assembly includes a connecting sleeve and a support leg at the bottom of the connecting sleeve. The top of the connecting sleeve has a tapered mounting groove, and the bottom of the irrigation main pipe is tapered to fit the groove inside the mounting groove.

[0013] In some embodiments, the support legs are located at the bottom of the connecting sleeve and are arranged in a triangular pattern.

[0014] In some embodiments, the connecting sleeve is a resilient rubber block.

[0015] In some embodiments, the support leg is a hollow plastic tube.

[0016] Compared with existing technologies, the significant advantages of this invention are:

[0017] Firstly, this invention utilizes drainage pipes evenly spaced along the length of a horizontal pipe with their lower outlets pointing vertically downwards. A flexible hose connects the drainage pipes to the irrigation nozzle mechanism. The irrigation nozzle mechanism comprises a vertical irrigation main pipe, a circular, upward-rotating delivery pipe, and atomizing nozzles detachably connected to the delivery pipe. Combined with a bottom support assembly, this achieves comprehensive, bottom-up irrigation of greenhouse crops. This unique structural design effectively prevents branches or crop leaves from obstructing the irrigation, significantly increasing the relative irrigation area, making irrigation more uniform, and substantially improving irrigation efficiency. It solves the problems of uneven irrigation and low efficiency caused by plant foliage obstruction in traditional irrigation methods.

[0018] Secondly, this utility model adopts a threaded connection method, connecting the connecting pipe of the atomizing nozzle to the internal thread at the opening of the delivery pipe through the external thread. This allows each atomizing nozzle to be easily and quickly replaced and installed when damaged, greatly improving the ease of use of the device and solving the problem of difficulty in replacing and repairing damaged nozzles in traditional irrigation devices.

[0019] Thirdly, in the support component of this utility model, the top of the connecting sleeve has a conical mounting groove that matches the bottom of the irrigation main pipe, ensuring a stable connection between the irrigation main pipe and the support component; the support legs are distributed in a triangular pattern at the bottom of the connecting sleeve, and the stability of the triangle is utilized to further enhance the support effect on the irrigation nozzle mechanism, ensuring the stability of the device during irrigation, avoiding the impact of the device shaking or tipping on irrigation, and solving the problem of insufficient stability of the irrigation device during use.

[0028] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0029] This utility model provides an improved automatic greenhouse irrigation device. The technical solution of this utility model is as follows:

[0030] Figure 1 - Figure 5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 - Figure 5 The present invention will be further described below.

[0031] like Figure 1 - Figure 2 As shown, an automatic irrigation device for a greenhouse includes a horizontal pipe 1. A hook is provided at the top of the horizontal pipe 1 to suspend it from the indoor ceiling. One end of the horizontal pipe 1 is connected to a water inlet pipe 101, and irrigation water is delivered to the horizontal pipe 1 by an external water pump. It also includes drain pipes 2, which are evenly spaced along the length of the horizontal pipe 1 with their lower outlets pointing vertically downwards; an irrigation nozzle mechanism, which is located directly below the drain pipes 2 corresponding to the water inlet pipe 101, and the top of the irrigation nozzle mechanism is connected to the bottom of the corresponding drain pipe 2 via a flexible hose 201; and a support assembly, which is movably connected to the bottom of the irrigation nozzle mechanism, allowing the irrigation nozzle mechanism to be inserted into the soil surface. The irrigation nozzle mechanism includes a vertical irrigation main pipe 3 and conveying pipes 301 arranged in a ring-shaped, upward-rotating pattern on the outer cylinder of the irrigation main pipe 3. Each conveying pipe 301 is detachably connected to an atomizing nozzle.

[0032] like Figure 2 - Figure 3As shown, in one embodiment, the atomizing nozzle includes a nozzle body 4 and a connecting pipe 401 connected to the bottom of the nozzle body 4. The outer cylinder of the connecting pipe 401 has an external thread, and the inner opening of the delivery pipe 301 has an internal thread. The atomizing nozzle is threadedly connected to the delivery pipe 301 through the connecting pipe 401. This threaded connection method allows for easy replacement of any damaged atomizing nozzle used for irrigation, greatly improving ease of use.

[0033] like Figure 2 and Figure 5 As shown, in one embodiment, the support assembly includes a connecting sleeve 5 and a support leg 501 at the bottom of the connecting sleeve 5. The top of the connecting sleeve 5 has a tapered mounting groove 502, and the bottom of the irrigation main pipe 3 is tapered to fit the groove inside the mounting groove 502. This arrangement achieves a stable connection between the irrigation main pipe 3 and the support assembly, ensuring the stability of the irrigation nozzle mechanism during operation.

[0034] like Figure 2 and Figure 5 As shown, in one embodiment, the support legs 501 are located at the bottom of the connecting sleeve 5, and the three sets of support legs 501 are arranged in a triangle. Triangles provide stability, and this arrangement further enhances the support stability of the support assembly for the irrigation nozzle mechanism, ensuring that the device will not easily tip over during irrigation.

[0035] like Figure 5 As shown, in one embodiment, the connecting sleeve 5 is an elastic rubber block. The elasticity of the rubber block makes the connection between the connecting sleeve 5 and the irrigation main pipe 3 more secure, and at the same time, it can buffer the vibration that may occur during irrigation to a certain extent, thus achieving better fixation and protection of the irrigation nozzle mechanism.

[0036] like Figure 5 As shown, in one embodiment, the support leg 501 is a hollow plastic tube. This design allows the support leg 501 to maintain a certain strength while reducing its own weight, making it easier to install and move. At the same time, the hollow structure also saves material costs.

[0037] The working principle and usage process of this utility model are as follows: An external water pump delivers irrigation water to the horizontal pipe 1 through the inlet pipe 101. The drain pipe 2 on the horizontal pipe 1 delivers the water vertically downwards to the irrigation nozzle mechanism. The irrigation nozzle mechanism is connected to the drain pipe 2 via a flexible hose 201. After the water enters the main irrigation pipe 3, it flows to each atomizing nozzle through the upwardly rotating conveying pipe 301. At this time, the vertically and spirally rotating atomizing nozzles can spray the irrigated crops from bottom to top in an all-round manner, avoiding the obstruction of branches or crop leaves and thus improving the relative irrigation area. The upwardly sprayed water solution will eventually flow downwards and collect on the soil surface, seeping into the roots and stems to complete normal irrigation. The support assembly is connected to the main irrigation pipe 3 via a connecting sleeve 5, and the support leg 501 supports the soil surface, ensuring that the entire irrigation nozzle mechanism is stably set among the crops. When the atomizing nozzle is damaged, it can be directly removed from the conveying pipe 301 by rotating the connecting pipe 401 and replaced with a new atomizing nozzle.

[0038] Improving water resource utilization: Because atomizing nozzles can spray water more evenly around crops, water waste is reduced and water resource utilization is improved. At the same time, the bottom-up spraying method allows water to penetrate into the soil better, reducing surface runoff and further improving water resource utilization efficiency.

[0039] Promoting air circulation and humidity regulation: The upward spraying of water mist can increase the humidity of the air inside the greenhouse to a certain extent. In addition, the rising and falling of the water mist promotes the air circulation inside the greenhouse, improves the microclimate environment of the greenhouse, and is conducive to the growth of crops.

[0040] Facilitates layout and adjustment: The horizontal pipe 1 is suspended from the indoor ceiling by hooks, and the drainage pipes 2 are evenly distributed on the horizontal pipe 1. This layout makes the entire irrigation system more flexible in the greenhouse. The position and number of irrigation nozzles can be easily adjusted according to the planting layout and needs of crops, improving the applicability of the system.

[0041] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
