Description

Technical Field

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

[0002] Agricultural irrigation is a key link in ensuring the healthy growth of crops and achieving stable and high agricultural yields. It plays an irreplaceable role in maintaining agricultural ecological balance and improving the quality and yield of agricultural products. As the problem of water scarcity becomes increasingly severe, water-saving irrigation technology has emerged and become an important direction for the development of modern agriculture. Agricultural water-saving irrigation devices are also constantly being updated and iterated to meet the needs of efficient use of water resources.

[0003] However, existing agricultural water-saving irrigation devices still have many shortcomings in practical applications. In the process of connecting the diversion pipe, traditional devices often adopt a relatively complex connection structure, which leads to cumbersome and time-consuming disassembly and assembly operations. For example, some devices use bolt and nut connections, which not only require tools for installation and disassembly, but also easily cause problems such as thread wear and stripping after repeated use, affecting the stability of the connection. Some devices also have poor sealing in their connection methods, which easily lead to water leakage after long-term use, wasting water resources and increasing maintenance costs. These problems greatly limit the efficiency and convenience of agricultural water-saving irrigation devices and cannot meet the needs of modern agriculture for rapid and efficient irrigation. In addition, existing diversion columns are often directly inserted into the ground, and when subjected to the forces generated by wind and the rotation of the water outlet, the vertical support at a single point is often not reliable enough.

[0004] Therefore, it is necessary to provide a new agricultural water-saving irrigation device to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an agricultural water-saving irrigation device.

[0006] The agricultural water-saving irrigation device provided by this utility model includes: a guide column, an inlet pipe fixedly connected to the bottom of the guide column, an outlet pipe rotatably connected to the top of the guide column, the outlet pipe and the inlet pipe being connected through a pipe inside the guide column, a diversion pipe provided on one side of the guide column, one end of the inlet pipe being connected to the diversion pipe through a connector, and the guide column being fixed to the ground by a support installed on its outer wall.

[0007] Preferably, the connector includes: a first connector, a second connector, a blocking ring, a limiting sleeve, a compression spring, a through hole, and a ball. One end of the water inlet pipe is fixedly connected to the first connector, and one end of the drain pipe is fixedly connected to the second connector. The outer wall of the second connector is fixedly connected to the blocking ring, and the outer wall of the second connector is fitted with a limiting sleeve. A compression spring is installed between the limiting sleeve and the blocking ring. One end of the compression spring is fixedly connected to the blocking ring, and the other end of the compression spring is fixedly connected to the limiting sleeve. Multiple sets of through holes are equidistantly opened on the side wall of the second connector, and a ball is slidably connected inside each through hole.

[0008] Preferably, the first connector has a groove in the middle, and the water inlet pipe and the drain pipe are connected by inserting a ball into the groove.

[0009] Preferably, the support component includes: a support sleeve, support legs, a torsion spring, and a threaded rod. The outer wall of the guide rod is fitted with a support sleeve, and multiple sets of support legs are equidistantly rotatably connected to the side of the guide rod. A torsion spring is symmetrically fixedly connected to the top of the support leg, one end of the torsion spring is fixedly connected to the support sleeve, and a threaded rod is threadedly connected to the side of the support sleeve.

[0010] Preferably, the inner diameter of the limiting sleeve gradually decreases from the first connector to the second connector, the distance between the inner wall of the limiting sleeve and the outer wall of the second connector is less than the diameter of the sphere, and the inner wall of the limiting sleeve is in pressure contact with the sphere.

[0011] Preferably, a rubber ring is fitted onto the end of the second connector near the first connector, and a rubber ring is installed inside the second connector.

[0012] Preferably, a knob is fixedly connected to one end of the threaded rod, and the outer wall of the knob is provided with anti-slip texture.

[0013] Preferably, the torque of each pair of torsion springs is equal to the torque of the supporting leg rotating around the supporting sleeve under gravity.

[0014] Compared with related technologies, the agricultural water-saving irrigation device provided by this utility model has the following beneficial effects:

[0015] Easy and secure fixing:

[0016] The support structure consists of support legs, torsion springs, and threaded rods. During installation, the support legs utilize ground resistance and the device's weight to overcome the torsion spring's torque, allowing for quick insertion into the ground for initial fixation without complex operations. When adjusting the height, the threaded rod can be rotated via a knob to precisely adjust the guide column height, adapting to different terrains and crop heights. Compared to traditional fixing methods, this method is simpler to operate and more efficient to adjust, greatly enhancing the device's applicability in various farmland environments.

[0017] Highly efficient and reliable connection:

[0018] The connector innovatively uses a combination of a ball, a limiting sleeve, and a compression spring. When installing the drainage tube, pulling the limiting sleeve releases the pressure on the ball, allowing the second connector to easily insert into the first connector. After releasing the limiting sleeve, the ball automatically engages with the groove under the action of the compression spring and the inner wall of the limiting sleeve, achieving a tight connection. No tools are required throughout the process, significantly shortening the installation time. The rubber ring not only enhances the sealing performance and prevents water leakage, but also prevents the ball from slipping out, ensuring the long-term stability and reliability of the connection structure and reducing maintenance costs.

[0019] Uniform and efficient irrigation:

[0020] The water outlet pipe, which is rotatably connected to the top of the guide column, automatically rotates using the reaction force generated when the water flows out, evenly spraying water to every corner of the farmland. Compared with traditional fixed water outlet devices, it effectively expands the irrigation range, eliminates irrigation dead zones, improves irrigation efficiency, reduces water waste, better meets the water needs of crops, and achieves the dual goals of water conservation and efficient irrigation.

[0021] Safe and convenient to carry:

[0022] During transport, the torsion spring automatically overcomes the weight of the support legs, causing them to retract and preventing accidental opening of the support legs. This prevents injury to personnel or damage to the device during handling, while also reducing the device's size, facilitating storage and transportation, reducing space occupation and transportation risks, and improving the device's portability and safety.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] Please see Figures 1 to 5 An agricultural water-saving irrigation device includes: a guide column 1, with an inlet pipe 2 fixedly connected to the bottom of the guide column 1 and an outlet pipe 3 rotatably connected to the top of the guide column 1. The outlet pipe 3 and the inlet pipe 2 are connected through a pipe inside the guide column 1. A diversion pipe 4 is provided on one side of the guide column 1, and one end of the inlet pipe 2 is connected to the diversion pipe 4 through a connector. The guide column 1 is fixed to the ground by a support installed on its outer wall. The connector includes: a first connector 5, a second connector 6, a blocking ring 7, a limiting sleeve 8, a compression spring 9, a through hole 10, and a ball 11. The first connector 5 is fixedly connected to one end of the inlet pipe 2, and the second connector 6 is fixedly connected to one end of the diversion pipe 4. The blocking ring 7 is fixedly connected to the outer wall of the second connector 6, and the limiting sleeve 8 is sleeved on the outer wall of the second connector 6. A compression spring 9 is installed between the limiting sleeve 8 and the blocking ring 7. One end of the compression spring 9 is fixedly connected to the blocking ring 7, and the other end of the compression spring 9 is fixedly connected to the limiting sleeve 8. Multiple sets of through holes 10 are equidistantly opened on the side wall of the second connector 6. A ball 11 is slidably connected inside each through hole 10. A groove 12 is opened in the middle of the first connector 5. The connection between the water inlet pipe 2 and the drain pipe 4 is achieved by the ball 11 being inserted into the groove 12. The inner diameter of the limiting sleeve 8 gradually decreases from the first connector to the second connector 6. The distance between the inner wall of the limiting sleeve 8 and the outer wall of the second connector 6 is less than the diameter of the ball 11. The inner wall of the limiting sleeve 8 is in contact with the ball 11. A rubber ring 17 is fitted on the end of the second connector 6 near the first connector 5. A rubber ring 17 is installed inside the second connector 6.

[0032] It should be noted that the design of the inner wall of the limiting sleeve 8 can prevent the ball 11 from sliding out of the opening of the limiting sleeve 8. The rubber ring 17 can not only keep the first connector 5 and the second connector 6 sealed, but also prevent the ball 11 from sliding out of the opening of the limiting sleeve 8.

[0033] Please see Figure 1 and Figure 2The support components include: a support sleeve 13, support legs 14, torsion springs 15, and threaded rods 16. The outer wall of the guide rod is fitted with a support sleeve 13. Multiple sets of support legs 14 are equidistantly rotatably connected to the side of the guide rod. Torsion springs 15 are symmetrically fixedly connected to the top of the support legs 14. One end of the torsion spring 15 is fixedly connected to the support sleeve 13. Threaded rods 16 are threadedly connected to the side of the support sleeve 13. A knob 18 is fixedly connected to one end of the threaded rod 16. Anti-slip textures are provided on the outer wall of the knob 18. The torque of every two torsion springs 15 is equal to the torque of the support legs 14 rotating around the support sleeve 13 under gravity.

[0034] It should be noted that the outer wall of the knob 18 has anti-slip texture for easy operation. When carrying this device in farmland, the torsion spring 15 will overcome the weight of the support leg 14, causing the support leg 14 to rotate around the support sleeve 13 and retract. This can prevent the support leg 14 from opening during carrying, making it convenient to transport and carry the device. At the same time, it can also avoid unnecessary collisions and damage to people or other objects caused by the support leg 14 during carrying.

[0035] The working principle of the agricultural water-saving irrigation device provided by this utility model is as follows:

[0036] Fixed guide column 1:

[0037] First, the agricultural water-saving irrigation device is transported to the designated location, such as the farmland where the guide column 1 needs to be installed. Since the support components include a support sleeve 13, support legs 14, torsion springs 15 and threaded rods 16, and the outer wall of the guide column 1 is fitted with a support sleeve 13, and multiple sets of support legs 14 are equidistantly rotatably connected to the side of the guide column 1, and torsion springs 15 are symmetrically fixedly connected to the top of the support legs 14, one end of the torsion spring 15 is fixedly connected to the support sleeve 13, and the torque of every two torsion springs 15 is equal to the torque of the support leg 14 rotating around the support sleeve 13 by gravity.

[0038] When fixing the device, first insert one of the support legs 14 into the ground. At this time, the resistance from the ground to the support leg 14 overcomes the torque of the torsion spring 15, so that the support leg 14 can be stably fixed on the ground. Then, pull the other two support legs 14 apart and insert them into the ground. The overall weight of the device further overcomes the torque of the torsion spring 15, so that all three support legs 14 are firmly fixed on the ground, forming a stable support structure, ensuring that the device will not easily shake or tip over during subsequent use.

[0039] Next, observe whether the height of the guide column 1 is appropriate. If it is not appropriate, rotate the knob 18 counterclockwise. Since the side of the support sleeve 13 is threaded with a threaded rod 16, rotating the knob 18 counterclockwise will cause the threaded rod 16 to move outward, thereby relieving the pressure on the guide column 1. After adjusting the guide column 1 to the appropriate height, rotate the knob 18 clockwise. At this time, the threaded rod 16 moves inward, pressing the guide column 1, so that the guide column 1 is tightly fixed on the support sleeve 13, thus completing the height adjustment and fixation of the guide column 1.

[0040] Install drainage tube 4:

[0041] When installing the drainage pipe 4, first pull the limiting sleeve 8. This is because the connector includes a first connector 5, a second connector 6, a blocking ring 7, a limiting sleeve 8, a compression spring 9, a through hole 10, and a ball 11. One end of the water inlet pipe 2 is fixedly connected to the first connector 5, and one end of the drainage pipe 4 is fixedly connected to the second connector 6. The outer wall of the second connector 6 is fixedly connected to the blocking ring 7, and the outer wall of the second connector 6 is fitted with a limiting sleeve 8. The limiting sleeve 8 is installed between the blocking ring 7. One end of the compression spring 9 is fixedly connected to the blocking ring 7, and the other end of the compression spring 9 is fixedly connected to the limiting sleeve 8. When the limiting sleeve 8 is pulled, the limiting sleeve 8 will squeeze the compression spring 9 and at the same time release the compression of the ball 11 by the limiting sleeve 8.

[0042] Then, the second connector 6 is inserted into the first connector 5. During the insertion process, the end of the first connector 5 will press against the ball 11. As the ball 11 slides within the through hole 10, the inner side of the ball 11 will be flush with the inner wall of the second connector 6, thus ensuring smooth insertion. After the first connector 5 and the second connector 6 are inserted, the position of the through hole 10 corresponds to the position of the groove 12 opened in the middle of the first connector 5. The limiting sleeve 8 is then released, and the limiting sleeve 8 moves towards the second connector 6 under the elastic force of the compression spring 9. Through the special design of its inner wall (the inner wall diameter gradually decreases from the first connector 5 to the second connector 6), the ball 11 is gradually squeezed into the groove 12. When the inner side of the ball 11 is stuck in the groove 12, the water inlet pipe 2 and the drainage pipe 4 are firmly connected. At the same time, a rubber ring 17 is sleeved on the end of the second connector 6 near the first connector 5. The rubber ring 17 can not only maintain a good seal between the first connector 5 and the second connector 6 to prevent water leakage, but also prevent the ball 11 from sliding out from the opening of the limiting sleeve 8.

[0043] Irrigation process:

[0044] After the diversion pipe 4 is connected to the inlet pipe 2, the external water source guides the water flow into the inlet pipe 2 through the diversion pipe 4. The water then flows through the pipe inside the guide column 1 to the outlet pipe 3. The water flows out from the side of the outlet pipe 3. During the outflow process, according to the principle of action and reaction, the reaction force of the water flow will push the outlet pipe 3 to rotate. In this way, the outlet pipe 3 can spray water evenly to the surrounding farmland during the rotation process, achieving the purpose of water-saving irrigation. At the same time, the staff can remotely control the pump power (the pump is a fixed structure, shown in the figure) to change the water flow size, thereby controlling the irrigation range of each irrigation device.

[0045] Carrying process:

[0046] When carrying this agricultural water-saving irrigation device, since the torque of each pair of torsion springs 15 is equal to the torque of the support leg 14 rotating around the support sleeve 13 under gravity, the torsion springs 15 will overcome the gravity of the support leg 14, causing the support leg 14 to rotate around the support sleeve 13 and retract. This can prevent the support leg 14 from opening during carrying, making it convenient to handle and carry the device, and at the same time, it can also avoid unnecessary collisions and damage to personnel or other objects caused by the support leg 14 during carrying.
