Description

Technical Field

[0001] This utility model belongs to the field of farmland irrigation technology, specifically relating to a high-standard farmland water conservancy irrigation system. Background Technology

[0002] A farmland irrigation system is a comprehensive system that uses artificial engineering measures to introduce water into farmland, distribute it to crops as needed, and coordinate with drainage facilities to regulate farmland water. Its core objective is to overcome the problem of uneven spatial and temporal distribution of natural rainfall, ensure crop water needs, and achieve high and stable agricultural yields. For example, Chinese patent CN 221011267 U discloses a high-standard farmland irrigation device, which relates to the field of farmland irrigation equipment technology. It includes a base plate with multiple dampers installed at the bottom. Each damper has a connecting plate, one end of a first spring is installed on the connecting plate, and the other end of the first spring is installed on the base plate. Each damper has a connecting block installed at its bottom end. A first bevel gear is installed at the end of a drive shaft, and a second bevel gear is installed on a moving shaft. The first and second bevel gears mesh with each other. A water pump and an irrigation pipe are installed on a water tank. A sealing ring is installed inside the irrigation pipe, and an adjustable irrigation pipe is rotatably installed inside the sealing ring.

[0003] In existing technologies, traditional farmland irrigation involves water flowing into the farmland from the irrigation inlet, advancing along the slope of the ground, and after the field is completely covered by water, continuous irrigation is used to maintain the surface water layer, allowing the water to seep vertically downwards. After the water inlet is closed, the surface water continues to seep down, evaporate, and eventually disappear. Due to uneven land, the water flow first covers low-lying areas, while higher areas receive insufficient water. To cover the entire field, irrigation time is forced to be extended, wasting a large amount of water resources. Moreover, the existing farmland irrigation systems have relatively fixed sprinkler heads, and if the sprinkler head angle needs to be changed, it needs to be manually adjusted, making the irrigation process time-consuming and labor-intensive. Therefore, this utility model proposes a high-standard farmland irrigation system. Utility Model Content

[0004] The purpose of this invention is to provide a high-standard farmland irrigation system that can integrate drip irrigation and sprinkler irrigation, and the sprinkler head angle can be automatically adjusted.

[0005] The specific technical solution adopted by this utility model is as follows: A high-standard farmland irrigation system includes a water pump, a drip irrigation system, and a sprinkler irrigation device. The water pump outlet is connected to the inlet of one end of the drip irrigation system via a flange. The outlet of the drip irrigation system is connected to a flexible hose via a flange. The flexible hose is connected to the inlet of the sprinkler irrigation device. The sprinkler irrigation device includes a base plate, on the upper surface of which an inlet pipe is fixedly installed. The flexible hose is connected to the inlet pipe. A connector is threaded to the upper end of the inlet pipe, and a nozzle is movably connected to the top of the connector. A plug-in assembly is provided at the connection between the connector and the nozzle. A rotating device is installed on the nozzle, which drives the nozzle to change its angle when spraying water.

[0006] Preferably, the outer diameter of the lower end of the nozzle is smaller than the outer diameter of the middle part of the nozzle, the plug-in assembly includes a limiting ring fixedly disposed on the outer wall of the lower end of the nozzle, and a bearing and a skeleton oil seal are connected between the lower end of the nozzle and the inner wall of the top of the connector.

[0007] Preferably, the plug-in assembly further includes a hollow ring fixed to the nozzle, the lower surface of the hollow ring being in contact with the top surface of the connector, and the plug-in assembly further includes a hollow column sleeved on the lower end of the nozzle; the lower surface of the hollow column is in contact with the upper surface of the limiting ring, the hollow column is in contact with the lower surface of the nozzle outer diameter transition, a circular hole is provided on one side of the hollow column, a first threaded hole is provided on the top of the connector, a first bolt is bolted to the first threaded hole, one end of the first bolt passes through the first threaded hole and is inserted into the circular hole, and the top end of the first bolt is not in contact with the nozzle surface.

[0008] Preferably, the rotating device includes a fixed block fixedly sleeved on the upper end of the nozzle, a shaft fixedly connected to the upper surface of the fixed block, a square block detachably installed on the top of the shaft, a cylindrical column movably sleeved on the shaft, a spring sleeved on the upper end of the cylindrical column, the upper end of the spring connected to the square block, a rotating rod installed on the side wall of the cylindrical column, the lower end of the spring fixedly connected to the rotating rod, a protrusion provided on the upper end of the rotating rod, the protrusion being located directly in front of the nozzle end, a baffle fixedly connected to the bend of the nozzle, and the lower end of the rotating rod being adapted to the baffle.

[0009] Preferably, multiple pairs of fixing plates are fixedly installed on the lower surface of the base plate, and a wheel is installed between a pair of fixing plates. Multiple square holes are opened in the middle of the wheel, and a second threaded hole is opened on the side wall of the fixing plate. A second bolt is bolted to the second threaded hole, and one end of the second bolt passes through the second threaded hole and is inserted into the square hole.

[0010] Preferably, a filter screen is installed on the inner wall of the water pump inlet; a handle is provided on the side wall of the base plate.

[0011] Preferably, the drip irrigation system includes a main pipe and branch pipes symmetrically arranged at equal intervals on the main pipe, wherein the branch pipes are provided with drip heads arranged in an array at equal intervals.

[0012] The technical effects achieved by this utility model are as follows: 1. Water sprays from the nozzle, impacting the protrusion on the rotating rod, generating driving force. The impact of the water pushes the rotating rod to rotate around its axis, while the spring deforms. The lower end of the rotating rod strikes the baffle as it rotates, causing the nozzle to change angle through mechanical linkage. After the impact, the spring returns, springing the rotating rod back to its initial vertical position. After resetting, the water flow from the nozzle impacts the protrusion again, repeating the above steps to form a continuous rotating motion, achieving 360° omnidirectional irrigation coverage from the nozzle. Ultimately, this enables integrated drip irrigation and sprinkler irrigation, and the sprinkler nozzle angle can be automatically adjusted.

[0013] 2. After a specific field is irrigated, the operator pulls the handle, and the traction force is transmitted through the handle to the wheels on the base plate, driving the entire device to move along the ground and drag the device to the next target field to be irrigated. After the wheels stop rolling, the second bolt is inserted into the square hole opened in the wheel through the second threaded hole to lock the wheel and prevent it from shaking during operation.

[0017] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0018] like Figures 1-8 As shown, a high-standard farmland irrigation system includes a water pump 8, a drip irrigation system 11, and a sprinkler irrigation device. The outlet of the water pump 8 is connected to the inlet of one end of the drip irrigation system 11 via a flange. The outlet of the drip irrigation system 11 is connected to a hose 12 via a flange. The hose 12 is connected to the inlet of the sprinkler irrigation device. The sprinkler irrigation device includes a base plate 1. An inlet pipe 2 is fixedly installed on the upper surface of the base plate 1. The hose 12 is connected to the inlet pipe 2. A connector 3 is threaded to the upper end of the inlet pipe 2. A nozzle 4 is movably connected to the top of the connector 3. A plug-in assembly 5 is provided at the connection between the connector 3 and the nozzle 4. A rotating device 6 is installed on the nozzle 4. When the nozzle 4 sprays water, the rotating device 6 drives the nozzle 4 to change its angle.

[0019] like Figures 1-8 As shown, in this utility model, the drip irrigation system 11 is pre-laid on the high-standard farmland. When the high-standard farmland needs irrigation, the input end of the water pump 8 is connected to the water source pipeline or placed inside the water source canal. The other end of the drip irrigation system 11 is connected to the hose 12 through a flange to achieve connection with the sprinkler irrigation device, supplying water to the sprinkler irrigation device. Part of the water provided by the water pump 8 is dripped from the drip irrigation system 11 for large-area drip irrigation, and part is sprayed from the sprinkler irrigation device, realizing integrated drip irrigation and sprinkler irrigation.

[0020] Preferably, the outer diameter of the lower end of the nozzle 4 is smaller than the outer diameter of the middle part of the nozzle 4. The plug-in assembly 5 includes a limiting ring 505 fixedly disposed on the outer wall of the lower end of the nozzle 4. A bearing 504 and a skeleton oil seal 506 are connected between the lower end of the nozzle 4 and the inner wall of the top of the connector 3.

[0021] Preferably, the plug-in assembly 5 further includes a hollow ring 501 fixed on the nozzle 4, the lower surface of the hollow ring 501 being in contact with the top surface of the connector 3, and the plug-in assembly 5 further includes a hollow column 502 sleeved on the lower end of the nozzle 4; the lower surface of the hollow column 502 being in contact with the upper surface of the limiting ring 505, and the hollow column 502 being in contact with the lower surface of the outer diameter transition of the nozzle 4, a round hole being opened on one side of the hollow column 502, a first threaded hole being opened on the top of the connector 3, a first bolt 503 being bolted to the first threaded hole, one end of the first bolt 503 passing through the first threaded hole and inserted into the round hole, and the top end of the first bolt 503 not being in contact with the surface of the nozzle 4.

[0022] like Figures 1-8 As shown, rocker arm irrigation uses mechanical rotation to spray water evenly and efficiently into farmland or green space. In practical applications, the hollow column 502 is adjusted so that the round hole on the side wall of the hollow column 502 is horizontally aligned with the first threaded hole on the side wall of the connector 3. The nozzle is then slowly inserted into the connector 3 until the lower surface of the hollow ring 501 is in contact with the upper surface of the connector 3, ensuring that the nozzle 4 will not fall off during operation. The hollow column 502 is seated on the upper surface of the limiting ring 505 by the fixed limiting ring 505 at the lower end of the nozzle 4, ensuring that the hollow column 502 will not slide down and fall off. Then, the first bolt 503 is rotated so that one end of the first bolt 503 passes through the first threaded hole and is inserted into the round hole, so that the nozzle 4 will not move upward during operation. However, the top surface of the first bolt 503 is not in contact with the side wall of the nozzle 4, so as not to hinder the rotation of the nozzle 4. The skeleton oil seal 506 is used to seal the lower end of the nozzle 4 with the inner wall of the connector 3, ensuring that there is no water leakage at the interface between the nozzle 4 and the connector 3 during operation.

[0023] Preferably, the rotating device 6 includes a fixing block 601 fixedly sleeved on the upper end of the nozzle 4, a shaft 602 fixedly connected to the upper surface of the fixing block 601, a square block 603 detachably installed on the top of the shaft 602, a cylindrical column 604 movably sleeved on the shaft 602, a spring 605 sleeved on the upper end of the cylindrical column 604, the upper end of the spring 605 connected to the square block 603, a rotating rod 606 installed on the side wall of the cylindrical column 604, the lower end of the spring 605 fixedly connected to the rotating rod 606, a protrusion 608 provided on the upper end of the rotating rod 606, the protrusion 608 being located directly in front of the end of the nozzle 4, a baffle 607 fixedly connected to the curved part of the nozzle 4, and the lower end of the rotating rod 606 being adapted to the baffle 607.

[0024] like Figures 1-8As shown, water sprays from the nozzle 4, impacting the protrusion 608 on the rotating rod 606, generating a driving force. The impact force of the water pushes the rotating rod 606 to rotate around the axis. At the same time, the spring 605 deforms, and the lower end of the rotating rod 606 impacts the baffle 607 as it rotates. Through mechanical linkage, the nozzle 4 changes its angle. After the impact, the spring 605 rotates back, returning the rotating rod 606 to its initial vertical position. After resetting, the water flow from the nozzle 4 impacts the protrusion 608 again. The above steps are repeated to form a continuous rotating motion, enabling the nozzle 4 to provide 360° omnidirectional irrigation coverage.

[0025] Preferably, multiple pairs of fixing plates 101 are fixedly installed on the lower surface of the base plate 1. A wheel 7 is installed between a pair of fixing plates 101. Multiple square holes are opened in the middle of the wheel 7. A second threaded hole is opened on the side wall 101 of the fixing plate. A second bolt 102 is bolted to the second threaded hole. One end of the second bolt 102 passes through the second threaded hole and is inserted into the square hole.

[0026] Preferably, the bottom plate 1 has a handle 10 on its side wall.

[0027] like Figures 1-8 As shown, after a specific field is irrigated, the operator pulls the handle 10, and the traction force is transmitted through the handle 10 to the wheel 7 on the base plate 1, driving the entire device to move along the ground and dragging the device to the next target irrigated field. After the wheel 7 stops rolling, the second bolt 102 is inserted into the square hole opened in the wheel 7 through the second threaded hole to lock the wheel 7, so that it will not shake during operation.

[0028] Preferably, a filter screen 9 is installed on the inner wall of the inlet end of the water pump 8.

[0029] like Figures 1-8 As shown, before the water source enters the water pump 8, it passes through the filter screen 9. The filter screen 9 intercepts suspended impurities, preventing impurities from wearing down the pump body impeller, extending the pump's lifespan, and preventing the nozzle 4 from clogging.

[0030] The drip irrigation system 11 includes a main pipe 111 and branch pipes 112 symmetrically arranged at equal intervals on the main pipe 111. The branch pipes 112 are provided with drip heads 113 distributed in an array at equal intervals.

[0031] like Figure 1 as well as Figure 2 As shown, in the drip irrigation system 11, part of the water source in the main pipe 111 enters the branch pipe 112 and is sprayed out from the drip head 113, while another part of the water source enters the sprinkler irrigation device through the hose 12 for sprinkler irrigation.

[0032] like Figures 1-8As shown, the working principle of this utility model is as follows: The rocker arm irrigation system distributes irrigation water evenly and efficiently to farmland or green space through mechanical rotation and spraying. In practical applications, the drip irrigation system 11 is pre-laid inside high-standard farmland. When irrigation is needed, the input end of the water pump 8 is connected to a water source pipe or placed inside a water source canal. A hose 12 is connected to the other end of the drip irrigation system 11 via a flange, connecting it to a sprinkler irrigation device to supply water. Part of the water provided by the water pump 8 is used for large-area drip irrigation from the drip irrigation system 11, and part is sprayed from the sprinkler irrigation device, achieving integrated drip and sprinkler irrigation. During sprinkler irrigation, water enters the connector 3 from the inlet pipe 2, and then... Connector 3 enters the nozzle 4, and water sprays out from the nozzle 4, impacting the protrusion 608 on the rotating rod 606, generating driving force. The impact force of the water pushes the rotating rod 606 to rotate around its axis, while the spring 605 deforms. The lower end of the rotating rod 606 strikes the baffle 607 as it rotates, causing the nozzle 4 to change angle through mechanical linkage. After the impact, the spring 605 rotates back, returning the rotating rod 606 to its initial vertical position. After resetting, the water flow from the nozzle 4 impacts the protrusion 608 again, repeating the above steps to form continuous rotational motion, achieving 360° omnidirectional irrigation coverage from the nozzle 4. Ultimately, drip irrigation and sprinkler irrigation can be carried out simultaneously.

[0033] After irrigation is completed, the water pump 8, drip irrigation system 11, and sprinkler irrigation device are disassembled, stored, and preserved. Figure 1 as well as Figure 2 In the diagram, the notch in the main pipe 111 indicates that the drip irrigation system 11 has multiple arrays of branch pipes 112, and the notch in the hose 12 indicates that the length of the hose 12 can be adapted to a certain area of ​​land and can be adapted to the moving position of the sprinkler device.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
