This device improves water utilization and saves agricultural water. In actual use, the above-mentioned application requires high-quality water pipes and high water pressure due to the irrigation being located at the top of the greenhouse. It is also troublesome to install and increases the load-bearing capacity of the greenhouse. Utility Model Content
[0003] In order to overcome the shortcomings of the existing technology, this utility model provides an irrigation device for seedling greenhouses, which has the advantages of easy installation and low water pressure requirements.
[0004] To achieve the above objectives, this utility model provides the following technical solution: an irrigation device for a seedling greenhouse, comprising a fixed sleeve, a connecting pipe slidably connected inside the fixed sleeve, a limiting plate fixedly installed at the bottom of the connecting pipe, a fixed pipe fixedly installed at the top of the connecting pipe, a rotating groove and a sliding groove opened inside the fixed pipe, a limiting rod slidably connected inside the sliding groove, a connecting rod fixedly installed on the side of the limiting rod away from the center point of the fixed pipe, a nozzle fixedly installed on the side of the connecting rod away from the limiting rod, and a spray nozzle opened on the surface of the nozzle.
[0005] As a preferred embodiment of this utility model, a water inlet pipe interface is fixedly installed on the surface of the fixing sleeve, a base is fixedly installed on the bottom of the fixing sleeve, and a reinforcement hole is provided on the surface of the base.
[0006] As a preferred embodiment of this utility model, the inside of the fixing sleeve is hollow, the bottom of the connecting tube is sealed where it contacts the fixing sleeve, and the inside of the connecting tube is also hollow.
[0007] As a preferred embodiment of this utility model, the top of the fixed tube is located inside the nozzle, and there are multiple limiting rods, all of which are engaged inside the sliding groove.
[0008] As a preferred embodiment of this utility model, there are multiple connecting rods, all of which are fixedly connected to the nozzles, and there are multiple spray nozzles, all of which are located above the fixed pipe.
[0009] As a preferred embodiment of this utility model, the base is circular and relatively heavy, and there are multiple reinforcing holes, all of which are located inside the base.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model features a connecting pipe that slides inside a fixed sleeve, a fixed pipe that is fixedly installed above the connecting pipe, and a nozzle that is rotatably connected above the fixed pipe. The nozzle has a spray nozzle on its surface. When the device is in normal use, water pressure will lift the connecting pipe upwards after water is supplied, and the water will then enter the nozzle through the connecting pipe and the fixed pipe, and then be discharged outwards through the spray nozzle to achieve the watering effect. At the same time, because the height of the spray nozzle is raised by the connecting pipe, the higher the spray nozzle, the farther the watering range, and the less equipment is required, thus achieving the effect of simple installation.
[0011] 2. This utility model has a reinforcement hole on the surface of the base. When the water pipe is connected to the water inlet pipe interface, the water pressure coming in will be relatively large. At this time, the device can be connected to the ground through the reinforcement hole by bolts or a sharp object. This ensures that when there is water pressure inside the fixed sleeve, the whole device will not collapse due to the large water pressure, thus improving the overall stability of the device.

[0014] 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.
[0015] Example 1, as Figure 1 Figure 2 and Figure 3 As shown, this utility model provides an irrigation device for seedling greenhouses, including a fixed sleeve 1, a connecting pipe 2 slidably connected inside the fixed sleeve 1, a limiting plate 3 fixedly installed at the bottom of the connecting pipe 2, a fixed pipe 4 fixedly installed at the top of the connecting pipe 2, a rotating groove 5 and a sliding groove 6 opened inside the fixed pipe 4, a limiting rod 7 slidably connected inside the sliding groove 6, a connecting rod 8 fixedly installed on the side of the limiting rod 7 away from the center point of the fixed pipe 4, a nozzle 9 fixedly installed on the side of the connecting rod 8 away from the limiting rod 7, and a spray nozzle 10 opened on the surface of the nozzle 9. The fixed sleeve 1 is hollow inside, the bottom of the connecting pipe 2 is sealed where it contacts the fixed sleeve 1, the connecting pipe 2 is also hollow inside, the top of the fixed pipe 4 is located inside the nozzle 9, there are multiple limiting rods 7, all of which are snapped into the sliding groove 6, there are multiple connecting rods 8, all of which are fixedly connected to the nozzle 9, and there are multiple spray nozzles 10, all of which are located above the fixed pipe 4. The nozzle 9 is hollow inside. When the water pressure is within the nozzle 9, the nozzle 9 will rotate due to the water pressure, thereby changing the direction of the spray nozzle 10. When the spray nozzle 10 sprays water outward, the water is higher and rotated by the nozzle 9, which makes the irrigation more uniform. At the same time, vegetables near the irrigation device can be watered. The water pressure and range are calculated, and another one is installed at the intersection, thereby saving the cost of the device to the greatest extent.
[0016] Example 2, as Figure 4 and Figure 5 As shown, a water inlet pipe interface 11 is fixedly installed on the surface of the fixed sleeve 1, and a base 12 is fixedly installed on the bottom of the fixed sleeve 1. A reinforcement hole 13 is opened on the surface of the base 12. The base 12 is circular and heavy. There are multiple reinforcement holes 13, and all of the multiple reinforcement holes 13 are located inside the base 12. The base 12 is in contact with the ground, which not only ensures the stability of the device, but also ensures that the device is vertical by adjusting the angle of the base 12 with respect to the ground after installation. At the same time, multiple reinforcing holes 13 are located above the ground, and the device is secured to the ground by bolts or long fixing cones, which effectively ensures the overall stability of the device.
[0017] Working principle and usage process of this utility model: First, the pipes are laid along the ground to achieve the effect of rapid installation and improved installation efficiency by using the shortest distance and simplest layout. Next, place the entire device in a suitable position, and at the same time, place the base 12 in a suitable position. Then, engage the device with the reinforcing hole 13 using bolts to make the device more securely installed. At this point, connect the water inlet 11 to the water pipe so that the device can flow water normally. When water enters the interior of the fixed sleeve 1, it will generate a large water pressure. At this point, push the connecting pipe 2 upward so that the device can effectively increase its height, thereby ensuring that the water can be discharged further and the irrigation area can be larger. Finally, due to the influence of water pressure, the nozzle 9 will rotate at the top of the fixed pipe 4. At this time, the water output from the spray nozzle 10 will be more even, and the vegetables around will be evenly watered, thus saving installation efficiency while ensuring the rationality of watering.
