Description

Technical Field

[0001] This invention relates to the field of agricultural sprinkler irrigation, and in particular to a mobile sprinkler irrigation machine for slopes, a continuous water supply sprinkler irrigation system, and a sprinkler irrigation method. Background Technology

[0002] Sprinkler irrigation is an irrigation method that uses water pumps and pipeline systems or the drop in elevation of natural water sources to spray pressurized water into the air, breaking it down into small droplets or mist that falls onto plants and the ground. Sprinkler irrigation includes stationary sprinkler irrigation, semi-stationary sprinkler irrigation, and mobile sprinkler irrigation, and is characterized by water conservation, no damage to soil structure, and strong adaptability.

[0003] Mobile sprinkler irrigation is the current trend in agricultural sprinkler irrigation, and its application in field irrigation is becoming increasingly widespread. There are two main methods for supplying water to mobile sprinkler irrigation systems in field irrigation: pipeline supply and furrow supply. Mobile sprinkler irrigation systems in field irrigation mainly include two types: reel-type mobile sprinkler irrigation systems and horizontally moving mobile sprinkler irrigation systems. The reel-type sprinkler irrigation system consists of a reel truck and a sprinkler truck. The reel truck carries the reel and provides water pressure. The front end of the reel connects to the sprinkler truck, and the rear end connects to the water source. The sprinkler truck is towed by a tractor to pull the hose and spray water. However, the travel distance of the sprinkler truck is limited by the length of the reel, and completing the entire irrigation process requires constant relocation and changing of water connection points. Both hose deployment and relocation require tractor towing. For example, CN109042252A, by adding a power source to the sprinkler truck and designing a water tank volume adjustment device, allows the sprinkler truck to add water and increase weight while moving forward, giving it sufficient traction to pull the hose and enabling self-propelled spraying operations. When retracting, water is released to reduce weight and decrease hose retraction resistance, thus solving the problem of relying on external power for hose deployment. However, it still cannot solve the inconvenience caused by carrying a large hose reel and the limitation on hose length during operation. Large-scale horizontal mobile sprinkler irrigation machines are even more massive, with trusses hundreds or even thousands of meters long. They commonly use trench water supply and are suitable for large areas of flat land, especially for regular long plots where they are highly efficient. However, they are not suitable for small plots. For example, patent application CN108207581A discloses a lightweight, simplified, intelligent, self-propelled, horizontal cantilever mobile sprinkler irrigation machine. It has a water suction pipe assembly and a power pump assembly on its walking frame. The water suction pipe assembly and the power pump assembly work together to pump water from the ditch and complete the sprinkler irrigation operation through the sprinkler assembly. This overcomes the problem that large sprinkler irrigation machines are not suitable for small plots of land. However, there is still no better solution for the problem of continuous water supply through channels when irrigating sloping land. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention employs a slope-mobile sprinkler irrigation machine, a stepped trench, and a pipeline-based continuous water supply sprinkler irrigation system. Inclined racks and climbing gears are installed on the trenches and the slope-mobile sprinkler irrigation machine to improve terrain adaptability. On gentle slopes and flat ground, a scheme combining mobile water troughs and pipelines achieves continuous water supply sprinkler irrigation. Combined with appropriate sprinkler irrigation methods, this overcomes the problems of reel-type mobile sprinkler irrigation requiring pipe dragging and frequent relocation, as well as the high requirements of horizontal-moving sprinkler irrigation on specific plots and terrain. This achieves continuous water supply sprinkler irrigation on slopes without the need for pipe dragging by the mobile sprinkler irrigation machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mobile sprinkler irrigation machine for slopes includes a frame and an extension arm, an irrigation pump, and a power assembly mounted on the frame. The extension arm is mounted on top of the frame and has a sprinkler pipe. The power assembly provides power. The irrigation pump has a suction pipe with its lower end extending into a ditch. A ramp rack is mounted on the edge of the ditch, and a climbing gear that meshes with the ramp rack is located at the bottom of the frame.

[0007] Preferably, the climbing gear is controlled to extend and retract via a hydraulic rod, which is connected to the powertrain via a hydraulic pipe.

[0008] Preferably, the end of the suction pipe that extends into the trench is equipped with a third opening and closing plug controlled by a third float ball; the suction pipe is arranged on the front and / or rear side of the frame of the mobile sprinkler.

[0009] Preferably, the device also includes a guide rod and a wire connection lifter. The upper end of the guide rod is rotatably mounted on the bottom of the frame, and the lower end of the guide rod is provided with a guide wheel, which is an H-shaped roller that can be engaged with the edge of the trench and roll. The wire connection lifter is controlled by the power assembly, which drives the wire connection lifter to extend and retract the guide rod.

[0010] Preferably, the edge of the stepped ditch is a smooth, unobstructed edge.

[0011] Preferably, the bottom of the mobile sprinkler frame is also equipped with two actuation rods, which are located on the left and right sides of the guide rod respectively. The actuation rods are used to provide feedback on the contact of the guide rod, thereby adjusting the moving direction of the mobile sprinkler.

[0012] Preferably, the system also includes a frame and a central shaft tube, fertilizer pump, fertilizer preparation box, and intelligent control cabinet mounted on the frame. At least two pairs of wheels are installed below the frame. The intelligent control cabinet connects to and controls the irrigation pump and power assembly, which controls the wheel movement. The fertilizer pump draws fertilizer from the fertilizer preparation box, and the intelligent control cabinet also connects to and controls the fertilizer pump. Several small nozzles are installed on the water spray pipe, with a central nozzle installed at each end. A pipe cap is also installed at each end of the water spray pipe. The middle section of the water spray pipe is fixedly connected to the frame via the central shaft tube, which communicates with the water spray pipe. A cap is installed at the top of the central shaft tube. Equipped with a large nozzle, the central shaft tube has a turntable in the middle, and the lower end of the central shaft tube is connected to the irrigation pump through a water pump outlet pipe. The extended arm also has a fertilizer and pesticide spraying pipe, on which several fertilizer and pesticide nozzles are installed. Each of the spraying pipe, fertilizer and pesticide spraying pipe, fertilizer and pesticide nozzles, small nozzles, large nozzles, and medium nozzles is equipped with a water control valve. An intelligent control cabinet is connected to and controls the water control valves, which have built-in water outlet sensors. The extended arm is equipped with support rods and spray pipe cables. The left and right sides of the extended arm are constructed from multiple truss sections joined together by folding devices. A rotatable camera is installed on the top of the support rod, and the camera is connected to the intelligent control cabinet.

[0013] A continuous water supply sprinkler irrigation system includes a trench and a slope mobile sprinkler irrigation machine as described above. The trench is continuously set on the slope and has multiple partition walls inside. The trench is supplied with water by a water supply pipe, which is a fixed water pipe pre-buried underground. A first water outlet pile is set at intervals on the water supply pipe, and the outlet of the first water outlet pile is equipped with a first opening and closing plug controlled by a first float ball.

[0014] Preferably, the bottom of the partition wall is provided with a water outlet, and the water outlet of the partition wall is provided with a second opening and closing plug controlled by a second float ball;

[0015] Preferably, the water suction pipe is made of a flexible material, and the partition wall has a smooth surface.

[0016] Preferably, the system also includes a water tank, which is installed below the frame. A suction pipe can extend into the water tank to draw water. The water tank is a retractable water tank, which includes a retractable tank frame, a tank liner, a tank wheel, a tightening line, and a reel. The left and right sides of the tank frame are formed by multiple X-shaped metal components that are movably connected. The X-shaped metal components on the left and right sides are connected by multiple crossbars. The tank liner is placed inside the tank frame to form a water storage space. A connecting frame is fixedly installed below the frame. The front of the water tank is hung on the connecting frame. The reel is controlled by the power assembly. One end of the tightening line is fixed to the tail of the water tank, and the other end is fixed to the reel. Rotating the reel winds the tightening line, thereby causing the water tank to contract or expand.

[0017] Preferably, the water supply pipe, located on a gentle slope or flat ground, is laid on the surface. Multiple second water outlets are evenly spaced along the water supply pipe, each equipped with a solenoid valve. The solenoid valve has leads A and B. Wires A and B are installed on the outer side of the water tank wall, connected to the positive and negative terminals of the power supply equipment within the power assembly. Two electrical contacts are installed on each of the two wires at the front and rear ends of the water tank, respectively. The two leads of the solenoid valve also have two electrical contacts. When the water tank approaches a second water outlet, the electrical contacts of leads A and B on the solenoid valve contact the corresponding contacts of leads A and B at the front end of the water tank, causing the solenoid valve to open with a positive pulse current, and water flows from the second water outlet. When the water tank moves away from a second water outlet, the electrical contacts of leads A and B on the solenoid valve contact the corresponding contacts of leads B and A at the rear end of the water tank, causing the solenoid valve to close with a reverse pulse current.

[0018] As a preferred option, two or more mobile sprinkler irrigation machines can be connected by a water pipe and a navigation system to achieve joint and synchronous operation.

[0019] A continuous water supply sprinkler irrigation method, using a continuous water supply sprinkler irrigation system as described above.

[0020] The present invention, by adopting the above technical solution, has the following technical effects:

[0021] 1. The present invention discloses a mobile sprinkler irrigation machine and a continuous water supply system for hilly terrain. By setting up stepped trenches and installing climbing mechanisms on the mobile sprinkler irrigation machine and the trench edges, the mobile sprinkler irrigation machine can achieve continuous water supply irrigation without pipe pulling on hilly and mountainous terrain, reducing the limitations of plot layout and terrain; the combination of multiple sprinkler heads further increases the adaptability to complex terrain on slopes, greatly improving the applicability of mobile sprinkler irrigation and the adaptability of equipment.

[0022] 2. The continuous water supply sprinkler irrigation system provided by this invention uses a mobile water tank for water supply when applied to gentle slopes or flat land, eliminating the need for ditches and saving construction costs. Moreover, two or more sprinkler machines can work together in parallel, reducing the density of water supply pipes and ditches and increasing the spray width.

[0023] 3. The mobile sprinkler irrigation machine provided by this invention can operate efficiently on flat land, slopes and mountains. It does not require dragging pipes and does not need to be moved within the block. When the sprinkler irrigation machine is fully fueled, has a continuous water supply and does not malfunction, it can automatically cruise for a long time on gentle slopes and flat land along the water supply pipe and on slopes along the ditch.

[0024] 4. The application of the mobile sprinkler irrigation machine, continuous water supply sprinkler irrigation system and sprinkler irrigation method provided by this invention will promote the development of digital agriculture and smart agriculture and help build high-standard farmland.

[0041] Example 1:

[0042] like Figures 1 to 5 As shown, this invention discloses a mobile sprinkler irrigation machine for slopes, including a frame 1 and an extension arm, an irrigation pump 7, and a power assembly 17 mounted on the frame 1. The extension arm is mounted above the frame 1 and is equipped with a water spray pipe 21. The power assembly 17 provides the power source. The intelligent control cabinet 21 can be controlled via a mobile phone or computer terminal through wireless signal transmission, Bluetooth signal transmission, etc. The irrigation pump 7 is equipped with a suction pipe 8, the lower end of which extends into a ditch 2. The ditch 2 is equipped with multiple partition walls 5, and the edge of the ditch 2 is a smooth, unobstructed edge. A ramp rack 6 is installed on the edge of the ditch. A climbing gear 10 that meshes with the ramp rack 6 is provided at the bottom of the frame 1. The ramp rack 6 is preferably a metal rack, and the climbing gear 10 is preferably a metal gear for higher strength.

[0043] In this way, the partition 4 divides the trench 2 into multiple stepped water storage trenches. When the mobile sprinkler machine moves on the slope, it can draw water stored in the trench 2 through the irrigation pump 7 and the suction pipe 8. When going up a steep slope, the climbing gear 10 meshes with the inclined rack 6 on the trench 2 and rolls to push up the slope.

[0044] In this design, the climbing gear 10 is controlled to retract and extend via a hydraulic rod 11, which is connected to the power assembly 17 via a hydraulic pipe 12. Specifically, on flat ground, the climbing gear 10 retracts. When traveling on a slope, the climbing gear 10 engages with the inclined rack 6 on the ditch 2 under the push of the hydraulic rod 11, rolling and pushing uphill. After completing the ascent, the hydraulic rod 11 retracts, the climbing gear 10 of the mobile sprinkler disengages from the inclined rack 6 of the ditch 2, and the mobile sprinkler resumes normal operation.

[0045] To ensure the mobile sprinkler moves steadily along the trench 2, it includes a guide rod 13 and a wire rope lifting device 16. The upper end of the guide rod 13 is rotatably mounted on the bottom of the frame 1, and the lower end of the guide rod 13 is equipped with a guide wheel 14. The guide wheel 14 is an H-shaped roller that can roll along the edge of the trench 2, thus limiting its movement to the edge and providing navigation. The wire rope lifting device 16 is powered by the power assembly 17, which drives the device to extend and retract the guide rod 13. Specifically, the first pulley of the wire rope lifting device 16 is powered by the power assembly 17. One end of the pull rod cable of the wire rope lifting device 16 is fixed to the first pulley, and the other end is fixed to the guide rod 13. Rotating the first pulley winds the pull rod cable, thereby extending and retracting the guide rod 13.

[0046] Generally, the mobile sprinkler irrigation machine is also equipped with a satellite navigation receiving antenna 34 and an automatic driving controller 35 for satellite navigation and automatic driving. Both the satellite navigation receiving antenna 34 and the automatic driving controller 35 are connected to and controlled by the intelligent control cabinet 21. Two actuating rods 15 are also provided at the bottom of the upper frame 1 of the mobile sprinkler irrigation machine. The two actuating rods 15 are located on the left and right sides of the guide rod 13, respectively. The actuating rods 15 provide feedback on the contact with the guide rod 13 to adjust the movement direction of the mobile sprinkler irrigation machine. The actuating rods 15 are connected to the intelligent control cabinet 21. Specifically, under normal driving conditions, there is a gap between the actuating rods 15 and the guide rod 13. When the mobile sprinkler irrigation machine veers to one side, the guide rod 13 will contact one of the actuating rods 15. This actuating rod 15 provides feedback to the intelligent control cabinet 21, which then controls the mobile sprinkler irrigation machine to automatically correct its driving direction through the automatic driving controller.

[0047] A third opening and closing plug 8b, controlled by a third float ball 8a, is installed at one end of the water suction pipe 8 that extends into the trench 2. The third float ball 8a controls the third opening and closing plug 8b to open, and the mobile sprinkler pump draws water from the trench 2 through the irrigation pump 7 and the water suction pipe 8. When the water suction pipe 8 leaves the water surface and passes over the partition wall 5, the third float ball 8a controls the third opening and closing plug 8b to close, thereby ensuring that the water in the water suction pipe 8 is not lost during the process of passing over the partition wall 5.

[0048] In this design, the water suction pipe 8 is made of a flexible material, and the partition wall 5 is made with a smooth surface, which makes it easy for the water suction pipe 8 to pass smoothly over the partition wall 5 in the trench 2.

[0049] In one embodiment, the suction pipe 8 may be located only on the front or rear side of the frame 1; in another embodiment, there are two suction pipes 8, located on the front and rear sides of the frame 1 respectively. The third opening and closing plug 8b of one suction pipe 8 closes when it passes over the partition wall 5, while the third opening and closing plug 8b of the other suction pipe 8 is usually open in the water, thus ensuring that the irrigation of the mobile sprinkler is not interrupted.

[0050] This mobile sprinkler irrigation machine for slopes also includes a frame 1 and a central shaft tube 22, a fertilizer pump 18, a fertilizer preparation box 20, and an intelligent control cabinet 21 mounted on the frame 1. At least two pairs of wheels 101 are installed under the frame 1, with two wheels 101 in each pair installed on the left and right sides under the frame 1 respectively. The power unit 17 can control the movement of the wheels 101. The intelligent control cabinet 21 connects to and controls the irrigation pump 7 and the power unit 17. The fertilizer pump 18 is used to draw fertilizer from the fertilizer preparation box 20. The intelligent control cabinet 21 also connects to and controls the fertilizer pump 18.

[0051] The arm of the mobile sprinkler is composed of multiple truss sections. Generally, the left and right sides of the arm are each composed of three truss sections spliced ​​together by folding devices 29. In this way, the three truss sections on the left and right sides of the arm can be folded and retracted.

[0052] The extended arm is equipped with a water spray pipe 23 and a fertilizer and pesticide spray pipe 24. Several small nozzles 25 are installed on the water spray pipe 23, and a medium nozzle 26 is installed at each end of the water spray pipe 23. A pipe cap 33 is also installed at each end of the water spray pipe 23. The middle part of the water spray pipe 23 is fixedly connected to the frame 1 through a central shaft tube 22. The central shaft tube 22 is connected to the water spray pipe 23. A large nozzle 27 is installed at the top of the central shaft tube 22. A turntable 221 is provided in the middle of the central shaft tube 22. The lower end of the central shaft tube 22 is connected to the irrigation pump 7 through a water pump outlet pipe 9. Several fertilizer and pesticide spray nozzles 19 are installed on the fertilizer and pesticide spray pipe 24.

[0053] The large sprinkler head 27 and the two medium sprinkler heads 26 can provide supplementary irrigation at different distances and ranges; on irregular plots or plots with large elevation differences, full-circle sprinkler irrigation can be carried out with the large sprinkler head 27 as the center. Water control valves 28 are installed on the water pipe 23, fertilizer and pesticide spraying pipe 24, small sprinkler head 25, large sprinkler head 27, and medium sprinkler head 26 respectively. The intelligent control cabinet 21 is connected to and controls the water control valves 28. The water control valves 28 have built-in water outlet sensors. When the water control valves 28 are opened, if the water outlet sensor cannot detect water, a water shortage signal is issued.

[0054] The boom is equipped with a support rod 30 and a nozzle cable 31 to maintain the balance and stability of the boom. A rotatable camera 32 is installed on the top of the support rod 30. The camera 32 is connected to the intelligent control cabinet 21 and can rotate 360°.

[0055] This embodiment also provides a continuous water supply sprinkler irrigation system for slopes, including a trench 2 and a mobile sprinkler irrigation machine for slopes as described above. The trench 2 is continuously set on the slope, and the trench 2 is supplied with water by a water supply pipe 3, which is a fixed water pipe pre-buried underground.

[0056] In one embodiment, a first water outlet pile 4 is installed at regular intervals along the water supply pipe 3, and a first water outlet pile 4 is installed at each section of the stepped water storage ditch. The outlet of the first water outlet pile 4 is controlled by a first float ball 4a and a first opening and closing plug 4b. That is, when the water level in the ditch 2 drops to the low water level line, the first float ball 4a controls the first opening and closing plug 4b to open, and water flows out of the first water outlet pile 4. The position of the first float ball 4a rises as the water level in the ditch 2 rises, until the first float ball 4a rises to the high water level line, at which point the first float ball 4a controls the first opening and closing plug 4b to close, and the outlet of the first water outlet pile 4 is closed.

[0057] In the second scheme, the water supply pipe 3 may have a first water outlet 4 at one or more high-point trenches 2, and a water outlet at the bottom of the partition wall 5. The water outlet of the partition wall 5 is equipped with a second opening and closing plug 5b controlled by a second float 5a. When the stepped water storage trench at the lowest point is short of water, the second float 5a on the partition wall 5 above it moves downward under the influence of gravity, controlling the second opening and closing plug 5b to open, the water outlet of the partition wall 5 opens, and water flows from the upper-level stepped water storage trench into the stepped water storage trench, thereby ensuring that the water level in each stepped water storage trench remains unchanged.

[0058] Example 2:

[0059] When used on gentle slopes or flat land, the mobile sprinkler irrigation machine combines pipelines with a mobile water trough, enabling continuous irrigation without the need for canal construction, thus saving construction costs. In this embodiment, as shown... Figures 6 to 8 As shown, the mobile sprinkler irrigation machine for slopes also includes a water trough 36, which is hung below the frame 1. The suction pipe 8 extends into the water trough 36 to draw water. The water trough 36 is a retractable water trough, including a retractable trough frame 38, a trough liner 39, a trough wheel 40, a tightening line 41, and a second line wheel 42. The left and right sides of the trough frame 38 are formed by multiple X-shaped metal components that are movably connected. The X-shaped metal components on the left and right sides are connected by multiple crossbars. The trough liner 39 is placed inside the trough frame 38 to form a water storage space. Generally, the trough liner 39 is made of waterproof fabric. The connecting frame 43 is fixedly installed below the frame 1. The front of the water trough 36 is attached to the connecting frame 43. The second reel 42 is controlled by the power assembly 17. One end of the tension line 41 is fixed to the tail of the water trough 36, and the other end is fixed to the second reel 42. Rotating the second reel 42 winds the tension line 41, thereby causing the water trough 36 to contract or expand. In this way, when traveling on flat ground, this mobile sprinkler irrigation machine for sloping terrain can draw water from the water trough 36 through the branch pipes of the irrigation pump 7 and the suction pipe 8 for irrigation.

[0060] A water supply pipe 3, located on a gentle slope or flat ground, is laid on the ground surface. A solenoid valve 45, controlling the water flow, is installed on the second water outlet pile 37. The solenoid valve 45 has leads A45a and B45b. Wires A44a and B44b are installed on the outer wall of the water tank 36. These two wires are connected from the positive and negative terminals of the power supply equipment within the power assembly 17. Two electrical contacts are installed at the front and rear ends of the water tank 36, respectively. Two electrical contacts are also installed on the two leads of the solenoid valve 45. When the water tank 36 approaches the second water outlet pile… At time 37, the electrical contacts of wires A45a and B45b on the solenoid valve 45 contact the electrical contacts of wires A44a and B44b at the front end of the water tank 36, and the solenoid valve 45 receives a positive pulse current to open, and water flows out of the second water outlet 37; when the water tank 36 moves away from the second water outlet 37, the electrical contacts of wires A45a and B45b on the solenoid valve 45 contact the electrical contacts of wires B44b and A44a at the rear end of the water tank 36, and the solenoid valve 45 receives a reverse pulse current to close.

[0061] Since the second water outlet piles 37 are equidistantly set on the water supply pipe 3, and the distance between them is equal to the length of the telescopic water tank when it is opened, after the solenoid valve 45 on the first second water outlet pile 37 is closed, the solenoid valve 45 on the next second water outlet pile 37 will open, so the water flow will not be interrupted and a continuous water supply will be formed.

[0062] In this way, the water tank 36 on the mobile sprinkler irrigation machine is combined with the water supply pipe 3, so that the mobile sprinkler irrigation machine can spray irrigation while obtaining a continuous water source from the water tank 36 through the water supply pipe 3. This allows the mobile sprinkler irrigation machine to operate continuously for a long time, and the cost of channel construction can also be saved.

[0063] Meanwhile, the mobile sprinkler uses the water supply pipe 3 as a navigation route. That is, the guide wheel 14 can be locked in the water supply pipe 3 and roll along the water supply pipe 3. Combined with the use of the automatic driving controller, the mobile sprinkler can achieve continuous self-propelled operation.

[0064] In this embodiment, the outer wheel track of the grooved wheels on both sides of the water trough 36 is smaller than the inner wheel track of the wheels 101 on both sides of the sprinkler 1. The water supply pipe 3 and the second water outlet pile 37 are located between the grooved wheel 10 and the wheel 101 on the same side. The distance between the outer side of the grooved wheel arranged on the side of the water supply pipe 3 and the wheel 101 of the slope mobile sprinkler 1 is sufficient to provide space for the arrangement of the water supply pipe 3 and the second water outlet pile 37. The height of the water trough 36 is also less than the height of the frame 1 of the slope mobile sprinkler 1. The outlet of the second water outlet pile 37 extends above the water trough 36, and the top of the second water outlet pile 37 is located below the frame 1. In this way, the slope mobile sprinkler 1 can travel and operate on flat ground without obstruction.

[0065] Generally, the second water outlet piles 37 are equidistantly arranged, and the length of the water tank 36 is equal to or slightly greater than the distance between the two second water outlet piles 37.

[0066] When used on flat or gentle slopes, the powertrain 17 drives the hydraulic rod 11 via the hydraulic pipe 12 to retract the climbing gear 10.

[0067] In this solution, two or more mobile sprinkler irrigation machines can also work side by side, such as... Figure 9 As shown, the specific method involves opening the pipe caps 33 of the water pipes 23 of two adjacent mobile sprinkler irrigation machines and connecting the water pipes 23 of the two adjacent mobile sprinkler irrigation machines together through a connecting pipe. In this way, only one water supply pipe 3 is needed to achieve irrigation for two or more mobile sprinkler irrigation machines, thereby reducing the layout density of the water supply pipes 3 and the trenches 2 and increasing the sprinkler irrigation width. On flat land, only one water supply pipe 3 is needed to provide water to the main unit, and on sloping land, only one water supply pipe 3 and the trench 2 are needed to provide water to the main unit. Other sprinkler irrigation machines do not need to be piped or trenched, thereby reducing the layout density of the water supply pipes 3 and the trenches 2, increasing the sprinkler irrigation width, and further reducing the cost of pipeline facilities and trenching.

[0068] This solution also discloses a sprinkler irrigation method for a continuous water supply sprinkler irrigation system as described above.
