The top end of the rotating tube is located in the pipe column and connected to the end of the irrigation water pipe, and the rotating tube is fixedly connected to the storage tray. A third motor is installed on the bottom side of the gear box, and rotating teeth are installed at the output end of the third motor and the outside of the rotating tube, and the two rotating teeth are engaged with each other.

[0015] A working method of a solar-powered farmland irrigation device, the specific operating steps of the working method are as follows:

[0016] Step 1: Solar energy is converted into electrical energy through the solar panel and stored in the battery. The battery is used to power the first irrigation mechanism and the second irrigation mechanism. The first irrigation mechanism is placed on one side of the farmland. At this time, the second irrigation mechanism is moved to the other side of the farmland through the electric body. At this time, the pressure seat of the limit assembly rotates from a horizontal state to a vertical state. During the movement, the third motor works and realizes the rotation of the rotating pipe through the meshing transmission of the rotating gear, thereby realizing the rotation of the receiving disk of the second irrigation mechanism, and releasing all the irrigation water pipes wound on the pipe column. When the irrigation water pipe on the second irrigation mechanism is not long enough, the receiving disk of the first irrigation mechanism is rotated by the second motor to release the irrigation water pipe on the receiving disk. When the irrigation water pipe on the second irrigation mechanism is too long, the excess irrigation water pipe is rolled up and stored by rotating the receiving disk on the first irrigation mechanism.

[0017] Step 2: The fifth motor drives the worm to rotate, cooperates with the meshing worm gear, and then drives the installation shaft and the pressure seat to rotate, and then rotates the vertical pressure seat to the horizontal state, and contacts and limits the irrigation water pipe on the receiving tray of the first irrigation mechanism. At this time, the first motor drives the rotating shaft and the rotating seat to rotate, and then the receiving tray and the irrigation water pipe are flipped, and then the upward irrigation nozzle is rotated to face the ground. At the same time, the irrigation water pipe is located below the top protruding part of the 7-type column. The fourth motor drives the threaded rod to rotate, and then drives the threaded pressure rod to move upward until the irrigation water pipe is pressed between the 7-type column and the pressure rod, thereby achieving the sealing of the irrigation water pipe;

[0018] Step 3: When the first irrigation mechanism and the second irrigation mechanism move simultaneously, the water pump works to transport the water in the water pipe through the fixed pipe and the rotating pipe to the irrigation pipe, and then sprays the water to the crops in the field through the irrigation nozzle in the irrigation pipe, thereby irrigating the crops in the field;

[0019] Step 4: After the watering is completed, the pressure rod moves down first, then the storage plate is flipped over so that the watering nozzle is facing upward, the pressure seat rotates to a vertical state, and then when the first irrigation mechanism and the second irrigation mechanism approach each other, the storage plate rotates to wind and store the irrigation water pipe. When the winding is completed, the pressure seat rotates again to a horizontal state to limit and fix the irrigation water pipe.

[0020] The beneficial effects of the present invention are as follows: by rotating the receiving disks of the first irrigation mechanism and the second irrigation mechanism, a coordinated reeling and unreeling mechanism is realized, which can dynamically adjust the irrigation coverage range, and the length of the irrigation pipe automatically matches the width of the farmland, thereby achieving precise irrigation and reducing water resource loss during irrigation.

[0021] The irrigation hose and the irrigation nozzle can be flipped by flipping the storage tray. The position of the irrigation nozzle can be adjusted during winding to avoid reflection of the nozzle on the winding. The direction of the irrigation nozzle can also be flexibly adjusted during irrigation to ensure accurate and controllable irrigation direction.

[0022] The limiting assembly is equipped with several synchronously rotating pressure seats, which can rotate the pressure seats to a vertical state during the winding process to avoid blocking the irrigation nozzle, and can also rotate the pressure seats to a horizontal state after the winding is completed to limit and fix the irrigation pipe;

[0023] Suitable for field crop irrigation scenarios, it can improve water resource utilization by more than 30% compared to traditional fixed sprinkler systems, while reducing mobile irrigation labor costs by 60%. BRIEF DESCRIPTION OF THE DRAWINGS

The solar panel 4 converts solar energy into electrical energy and stores it in the battery 5. The battery 5 supplies power to the first irrigation mechanism 1 and the second irrigation mechanism 2. Columns 6 and 7-type columns 7 are installed on both sides of the top of the electric body 3. A rotating shaft 8 is rotatably installed between the columns 6 and 7-type columns 7, and the rotating shaft 8 is fixedly connected to the end of the rotating seat 10. A first motor 9 is installed on the outer side of the column 6. The output end of the first motor 9 is fixedly connected to the rotating shaft 8. The first motor 9 is operated to realize the flipping of the rotating seat 10 and the storage tray 11.

[0033] A storage tray 11 is rotatably mounted on the swivel seat 10, and a pipe column 12 is installed at the center of the storage tray 11. The pipe columns 12 of the first irrigation mechanism 1 and the second irrigation mechanism 2 are respectively connected to the two ends of the irrigation water pipe 13. The irrigation water pipe 13 is wound on the pipe column 12. Several irrigation nozzles 14 are evenly spaced on the irrigation water pipe 13, and a limiting component 15 is installed on the pipe column 12.

[0034] A second motor 16 is installed at the bottom center of the rotating seat 10 of the first irrigation mechanism 1. The output end of the second motor 16 is connected to the receiving tray 11. The second motor 16 realizes the rotation of the receiving tray 11 of the first irrigation mechanism 1. A gear box 17 is installed at the bottom center of the rotating seat 10 of the second irrigation mechanism 2. A rotating tube 20 is installed in the rotating seat 10 of the second irrigation mechanism 2. The top of the rotating tube 20 is located in the pipe column 12 and is connected to the end of the irrigation water pipe 13. The rotating tube 20 is fixedly connected to the receiving tray 11. A third gear is installed on the bottom side of the gear box 17. The motor 23, the output end of the third motor 23 and the outside of the rotating tube 20 are equipped with rotating teeth 22, the two rotating teeth 22 are engaged with each other, the water pump 18 is installed on the bottom side of the gear box 17, the water inlet end of the water pump 18 is installed with a water pipe 19, and the water outlet end of the water pump 18 is installed with a fixed tube 21. The bottom end of the rotating tube 20 is sleeved on the outside of the top end of the fixed tube 21, and the rotating tube 20 and the fixed tube 21 are rotatably connected. When the third motor 23 works, the meshing transmission of the rotating teeth 22 realizes the rotation of the rotating tube 20, thereby realizing the rotation of the storage tray 11 of the second irrigation mechanism 2.

[0035] A mounting groove 24 is provided on the side wall of the 7-shaped column 7 of the first irrigation mechanism 1. A threaded rod 25 is rotatably installed in the mounting groove 24, and the end of the threaded rod 25 is threadedly connected to the pressure rod 26. A fourth motor 27 is installed on the top of the 7-shaped column 7. The output end of the fourth motor 27 is connected to the threaded rod 25. When the fourth motor 27 works, it drives the threaded rod 25 to rotate, and then drives the threaded pressure rod 26 to move upward until the irrigation pipe 13 is pressed tightly between the 7-shaped column 7 and the pressure rod 26.

[0036] The limiting assembly 15 includes a cylinder 28, and a plurality of inner grooves 29 are opened at equal angles on the outside of the cylinder 28. A mounting shaft 30 is rotatably installed in the inner groove 29, and the mounting shaft 30 is connected to the end of the pressure seat 31. A worm gear 32 is installed on the mounting shaft 30, and a fifth motor 33 is installed on the top side of the cylinder 28. A worm 34 is installed at the output end of the fifth motor 33, and the worm 34 is meshed with the worm gear 32. The worm 34 is driven to rotate by the operation of the fifth motor 33, and cooperates with the meshed worm gear 32, thereby driving the mounting shaft 30 and the pressure seat 31 to rotate.

[0037] Working principle: The solar energy is converted into electrical energy through the solar panel 4 and stored in the battery 5, and the battery 5 is used to power the first irrigation mechanism 1 and the second irrigation mechanism 2. The first irrigation mechanism 1 is placed on one side of the farmland. At this time, the second irrigation mechanism 2 is moved to the other side of the farmland through the electric body 3. At this time, the pressure seat 31 of the limit assembly 15 rotates from a horizontal state to a vertical state. During the movement, the third motor 23 works and realizes the rotation of the rotating tube 20 through the meshing transmission of the rotating teeth 22, thereby realizing the rotation of the receiving plate 11 of the second irrigation mechanism 2, and all the irrigation water pipes 13 wound on the pipe column 12 are released. When the length of the irrigation pipe 13 on the second irrigation mechanism 2 is not enough, the second motor 16 is used to rotate the receiving tray 11 of the first irrigation mechanism 1 to release the irrigation pipe 13 on the receiving tray 11. When the length of the irrigation pipe 13 on the second irrigation mechanism 2 is too long, the receiving tray 11 on the first irrigation mechanism 1 is rotated to reel in the excess irrigation pipe 13. The fifth motor 33 drives the worm 34 to rotate, cooperates with the meshing worm gear 32, and then drives the installation shaft 30 and the pressure seat 31 to rotate, and then rotates the vertical pressure seat 31 to the horizontal state, so as to adjust the first irrigation mechanism 2 to a certain extent. The irrigation water pipe 13 on the receiving tray 11 of the mechanism 1 is contact-limited. At this time, the first motor 9 drives the rotating shaft 8 and the rotating seat 10 to rotate, thereby realizing the flipping of the receiving tray 11 and the irrigation water pipe 13, and then rotating the upward irrigation nozzle 14 to face the ground. At the same time, the irrigation water pipe 13 is located below the top protruding part of the 7-shaped column 7. The fourth motor 27 drives the threaded rod 25 to rotate, and then drives the threaded pressure rod 26 to move upward until the irrigation water pipe 13 is pressed between the 7-shaped column 7 and the pressure rod 26, thereby realizing the closure of the irrigation water pipe 13. When the first irrigation mechanism 1 and the second irrigation mechanism 2 are simultaneously During movement, the water pump 18 works to transport the water in the water pipe 19 through the fixed pipe 21 and the rotating pipe 20 to the irrigation water pipe 13, and then sprays the water to the crops in the farmland through the irrigation nozzle 14 in the irrigation water pipe 13 to achieve irrigation of the crops in the farmland. After the irrigation is completed, the pressure rod 26 first moves down, and then the storage tray 11 is flipped so that the irrigation nozzle 14 is facing upward, and the pressure seat 31 rotates to a vertical state. Then, when the first irrigation mechanism 1 and the second irrigation mechanism 2 approach each other, the storage tray 11 rotates to wind and store the irrigation water pipe 13. When the winding is completed, the pressure seat 31 rotates to a horizontal state again to limit and fix the irrigation water pipe 13.

[0038] By rotating the receiving tray 11 of the first irrigation mechanism 1 and the second irrigation mechanism 2, a coordinated reeling and unreeling mechanism is realized, which can dynamically adjust the irrigation coverage range. The length of the irrigation pipe 13 automatically matches the width of the farmland, thereby achieving precise irrigation and reducing water resource loss.

[0039] By flipping the storage tray 11, the irrigation water pipe 13 and the irrigation nozzle 14 can be flipped. When winding and unwinding, the position of the irrigation nozzle 14 can be adjusted to avoid reflection caused by the irrigation nozzle 14 on the winding and unwinding. The direction angle of the irrigation nozzle 14 can also be flexibly adjusted during irrigation to ensure that the irrigation direction is accurately controlled.

[0040] The limiting assembly 15 is provided with a plurality of synchronously rotating pressure seats 31. During the winding process, the pressure seats 31 can be rotated to a vertical state to avoid blocking the irrigation nozzle 14. After the winding is completed, the pressure seats 31 can be rotated to a horizontal state to limit and fix the irrigation pipe 13.

[0041] Suitable for field crop irrigation scenarios, it can improve water resource utilization by more than 30% compared to traditional fixed sprinkler systems, while reducing mobile irrigation labor costs by 60%.
