Description

Technical Field

[0001] This utility model relates to the field of irrigation technology, specifically to an irrigation device. Background Technology

[0002] Irrigation is the most crucial aspect of agricultural production; its adequacy directly impacts subsequent crop yields. Irrigation systems are devices or systems used to deliver water to farmland, gardens, greenhouses, and other areas to provide plants with the water they need for growth. Different irrigation methods and technologies are employed.

[0003] In agricultural irrigation, irrigation devices are used to spray water onto farmland. Existing irrigation devices have nozzles mounted on fixed supports with no height adjustment, making them suitable for low-growing crops. However, as crops grow, their height changes significantly. Because the existing irrigation devices have a fixed height, if the nozzles are too high during the seedling stage, the impact of water droplets may damage the seedlings. If the nozzles are too low during the ripening stage, water may not reach the top of the crop, affecting yield. Utility Model Content

[0004] The purpose of this utility model is to provide an irrigation device to solve the problem mentioned in the background art: during the growth process of crops, the height of the plants will change significantly. Existing irrigation devices, due to their fixed height, may cause damage to the seedlings if the nozzle is too high during the seedling stage, or if the nozzle is too low during the maturity stage, the water will not be able to reach the top of the crop, thus affecting the yield.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an irrigation device, comprising a base and an irrigation section:

[0006] The irrigation section is located on the top of the base. The irrigation section has a fixed tube located on the top of the base. A nested tube is vertically and slidably nested outside the fixed tube. A limiting sleeve is horizontally and slidably located outside the nested tube. The limiting sleeve passes through the nested tube and engages with the fixed tube to fix the position of the nested tube. A rotating nozzle is rotatably located on the top of the nested tube.

[0007] By adopting the above technical solution, the height of the rotating nozzle can be adjusted by sliding the nested tube to adapt to the irrigation needs of different crops. At the same time, the locking connection between the limiting sleeve and the fixed tube ensures that the nested tube is firmly fixed and avoids displacement due to water pressure during irrigation.

[0008] Preferably, the base has a stake fixedly disposed at the bottom of the base, the stake being a triangular prism.

[0009] By adopting the above technical solution, the gripping force between the base and the ground can be enhanced by using triangular prism-shaped stakes, preventing the device from tilting or tipping over in soft soil.

[0010] Preferably, the bottom of the rotary nozzle has a rotary groove, the top of the nested tube is embedded in the rotary groove and rotatably connected to the rotary nozzle, and the side of the rotary nozzle has three nozzles with inclined angles.

[0011] By adopting the above technical solution, the rotation of the rotating nozzle and the tilting of the nozzle can achieve multi-angle scattering of water flow, expand the irrigation coverage area, and improve water resource utilization.

[0012] Preferably, the bottom side of the fixed pipe has a water inlet, and a rubber ring is nested at the position where the side of the fixed pipe abuts against the inner wall of the nested pipe.

[0013] By adopting the above technical solution, an external water source can be connected through the water inlet, and the rubber ring seals the gap between the fixed pipe and the nested pipe to prevent water leakage.

[0014] Preferably, the irrigation section also has a spring disposed inside the limiting sleeve, the limiting sleeve having a groove inside for limiting the lateral displacement of the spring, the spring being located between the limiting sleeve and the nested tube.

[0015] By adopting the above technical solution, the elastic force of the spring can be used to push the limiting sleeve to move and engage with the fixed tube, assisting the limiting sleeve to reset, making it convenient for users to adjust the height of the nested tube with one hand.

[0016] Preferably, the outer side of the limiting sleeve is decorated with anti-slip textures.

[0017] By adopting the above technical solution, the anti-slip texture can increase the friction when the user operates the limiting sleeve, thus preventing the hand from slipping.

[0018] Preferably, the irrigation section also has two inserts disposed on the inner wall of the limiting sleeve. The side of the nested tube has a perforation, through which the insert passes and slides laterally with the nested tube.

[0019] By adopting the above technical solution, the limiting sleeve can be guided to move laterally through the cooperation of the insert and the perforation, ensuring the stability of its movement trajectory.

[0020] Preferably, the irrigation section also has a limiting groove formed on the side of the fixed pipe, and several limiting grooves are formed vertically, with the insert block engaging with the limiting groove.

[0021] By adopting the above technical solution, the nested pipe can be locked at multiple heights by engaging with the limiting grooves of different heights, thus meeting the needs of precision irrigation.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting up an irrigation part, the height of the rotating nozzle can be adjusted by sliding the nested tube to adapt to the irrigation needs of different crops. At the same time, the locking connection between the limiting sleeve and the fixed tube ensures that the nested tube is firmly fixed, avoiding displacement caused by water pressure during irrigation. This allows the irrigation device to adapt to different irrigation needs by adjusting its own height, thereby improving irrigation efficiency. The device has a simple structure, is easy to operate, is suitable for irrigating crops at different heights, and has strong stability, making it adaptable to various terrain conditions.

[0030] 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.

[0031] Example 1

[0032] Please see Figure 1 , Figure 2 and Figure 3 This embodiment provides a technical solution: an irrigation device, including a base 1 and an irrigation section 2.

[0033] Irrigation unit 2 is located on top of base 1. Irrigation unit 2 has a fixed tube 201 located on top of base 1. A nested tube 202 is vertically and slidably nested outside the fixed tube 201. A limiting sleeve 204 is laterally slidably located on the outside of the nested tube 202. The limiting sleeve 204 passes through the nested tube 202 and engages with the fixed tube 201 to fix the position of the nested tube 202. A rotating nozzle 203 is rotatably mounted on the top of the nested tube 202. By adopting the above structural design, the height of the rotating nozzle 203 can be easily adjusted by sliding the nested tube 202, thereby adapting to the irrigation needs of crops at different growth stages. At the same time, the engaging connection between the limiting sleeve 204 and the fixed tube 201 ensures that the nested tube 202 remains stable and fixed during use, effectively preventing displacement caused by water pressure during irrigation and ensuring the accuracy and stability of irrigation.

[0034] Example 2

[0035] Please see Figure 4 , Figure 5 and Figure 6 This embodiment provides a technical solution: an irrigation device, including an irrigation section 2, a fixed pipe 201, and a nested pipe 202.

[0036] A stake 101 is fixedly installed at the bottom of the base 1. This fixing method is a conventional detachable fixing method, such as bolt connection or snap-fit ​​connection. The stake 101 is a triangular prism. This triangular prism shape significantly enhances the grip of the base 1 on the ground, especially in soft soil conditions. It effectively prevents the device from tilting or tipping over during use, ensuring the stability of irrigation operations. In practical applications, the triangular prism structure has better torsional resistance than the traditional cylindrical design, and can adapt to more complex terrain conditions.

[0037] The bottom of the rotating nozzle 203 is provided with a rotating groove, and the top of the nested tube 202 is embedded in the rotating groove and rotatably connected to the rotating nozzle 203. The side of the rotating nozzle 203 is provided with three nozzles with inclined angles. The rotation of the rotating nozzle 203 and the inclined nozzles can realize multi-angle scattering of water flow, expand the irrigation coverage area, and improve water resource utilization.

[0038] The bottom side of the fixed pipe 201 has a water inlet, which is connected to the water supply pipe. A rubber ring is nested at the position where the side of the fixed pipe 201 abuts against the inner wall of the nested pipe 202. The rubber ring is made of aging-resistant material and has a service life of more than 5 years. It can be connected to an external water source through the water inlet. The rubber ring seals the gap between the fixed pipe 201 and the nested pipe 202 to prevent water leakage.

[0039] A spring 205 is installed inside the limiting sleeve 204. The limiting sleeve 204 has a groove inside to limit the lateral displacement of the spring 205. The spring 205 is located between the limiting sleeve 204 and the nesting tube 202. The spring 205 is in the open state when it is not subjected to external force. The spring 205 is made of stainless steel and has undergone a special heat treatment process to ensure that it remains unchanged for a long time. The elastic force of the spring 205 can push the limiting sleeve 204 to move and engage with the fixed tube 201, assisting the limiting sleeve 204 to reset, and making it convenient for the user to operate the height adjustment of the nesting tube 202 with one hand.

[0040] The outer side of the limiting sleeve 204 is decorated with anti-slip textures, which can increase the friction when the user operates the limiting sleeve 204 and prevent the hand from slipping.

[0041] An insert 207 is integrally provided on the inner wall of the limiting sleeve 204. There are two inserts 207. A through hole 208 is provided on the side of the nested tube 202. The insert 207 passes through the through hole 208 and slides laterally with the nested tube 202. The limiting sleeve 204 can be guided to move laterally by the cooperation of the insert 207 and the through hole 208 to ensure its movement trajectory is stable.

[0042] A limiting groove 206 is formed on the side of the fixed pipe 201. Several limiting grooves 206 are arranged vertically. The insert block 207 engages with the limiting groove 206. By engaging the insert block 207 with the limiting grooves 206 at different heights, multiple height locks of the nested pipe 202 can be achieved, meeting the needs of precision irrigation.

[0043] Working principle: First, the base 1 is fixed in the soil by the stake 101 to ensure the stability of the device. The external water supply pipe is connected to the inlet of the fixed pipe 201. The water flows through the fixed pipe 201 into the nested pipe 202 and finally sprays out from the rotating nozzle 203. When the nozzle height needs to be adjusted, the user can hold the limiting sleeve 204 and pull it outward to make the insert 207 disengage from the current limiting groove 206. At this time, the spring 205 is compressed. Then, the user can slide the nested pipe 202 up and down to the desired height, release the limiting sleeve 204, and the spring 205 rebounds to push the insert 207 into the limiting groove 206 of the corresponding height to complete the height locking. During irrigation, the water flow impacts the inclined nozzle of the rotating nozzle 203, causing it to rotate automatically and achieve 360° uniform spraying, improving irrigation efficiency. The rubber ring ensures the sealing between the nested pipe 202 and the fixed pipe 201 to prevent leakage. The device has a simple structure, is easy to operate, is suitable for irrigating crops at different heights, and has strong stability, adapting to various terrain conditions.
