Technical Field

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

[0002] Farmland irrigation is a crucial aspect of agricultural production, significantly impacting crop growth and yield. To improve irrigation efficiency and flexibility, mobile sprinkler irrigation systems have become widely used. These systems typically consist of a movable frame, a water tank mounted on the frame, and irrigation booms distributed along both sides of the frame. The booms are equipped with multiple nozzles, enabling uniform spraying over a large area, suitable for irrigating farmland of varying sizes.

[0003] However, existing mobile sprinkler irrigation equipment still has certain limitations in practical use. In particular, in order to meet the needs of irrigation coverage, the spray boom is often designed to be long. While this is beneficial to improve efficiency during irrigation operations, in non-operational states such as transportation or storage, the long spray boom leads to a large overall size of the equipment and occupies a lot of space, further limiting the portability and practicality of the equipment, and making it difficult to meet users' needs for flexibility and convenience.

[0023] like Figures 1 to 6 As shown, a portable farmland irrigation device includes a cart frame 1, an irrigation water tank 2 fixedly connected to the upper end of the cart frame 1, an inlet pipe provided at the upper end of the irrigation water tank 2, a stirring rod rotatably connected inside the irrigation water tank 2, stirring blades 19 fixedly connected to the outer wall of the stirring rod, and a motor 18 for driving the stirring rod to rotate fixedly connected to the upper end of the irrigation water tank 2.

[0024] Both sides of the irrigation tank 2 are fixedly connected to fixed side plates 3, and folding brackets are hinged to both sides of the fixed side plates 3. Both sides of the irrigation tank 2 are provided with storage frames 17 that cooperate with the folding brackets. The folding bracket includes at least one connecting section plate 4 that is hinged and connected in series end to end. A fixing mechanism is provided between adjacent connecting section plates 4. An irrigation spray rod 5 is fixedly connected to one side of each connecting section plate 4. At least one irrigation nozzle 6 is provided on the outer wall of the irrigation spray rod 5 along the length direction. A detachable connection is provided between adjacent irrigation spray rods 5. The connecting pipe 7 has external threads at both ends of the irrigation spray bar 5, and the inner wall of the connecting pipe 7 has internal threads that mate with the external threads. A water pump 14 is fixedly connected to both sides of the irrigation water tank 2. A water pump 16 extending to the bottom of the irrigation water tank 2 is fixedly connected to the output end of the water pump 14. A filter screen box 20 that mates with the water pump 16 is fixedly connected to the irrigation water tank 2. A water outlet hose 15 is fixedly connected between the output end of the water pump 14 and the adjacent irrigation spray bar 5. A sealing plug is fixedly connected to the end of the irrigation spray bar 5.

[0025] One end of the connecting plate 4 is fixedly connected to a flexible connecting strip 10, and the other end of the flexible connecting strip 10 is fixedly connected to a connecting insert plate 11. The other end of the connecting plate 4 is provided with a connecting slot 21 that mates with the connecting insert plate 11. The bottom surface of the connecting slot 21 is provided with a positioning slot. A positioning post 12 is slidably inserted into the positioning slot. A positioning spring 13 is fixedly connected between the positioning post 12 and the inner wall of the positioning slot. The bottom surface of the connecting plate 4 is provided with a positioning insertion hole 24 that mates with the positioning post 12. The bottom surface of the connecting insert plate 11 is provided with an adjusting block 23. The bottom surface of the connecting plate 4 is provided with an adjusting hole 22 that mates with the adjusting block 23. A pressing ball 25 is rotatably connected to the end of the positioning post 12. One end of the connecting plate 4 is fixedly connected to a limiting insert plate 8, and the other end is provided with a limiting slot 9 that mates with the limiting insert plate 8.

[0026] In practical use, the operator first moves the device described in this utility model to the farmland area to be irrigated via the trolley frame 1. If the device is in the storage state, the folding brackets on both sides and the irrigation spray rods 5 on them are all folded up and placed in the storage frame 17.

[0027] Before starting the operation, the operator lifts the folding bracket from the storage box 17 and unfolds each connecting section plate 4 in sequence. During unfolding, adjacent connecting section plates 4 are rotated around the hinge point until they are fully unfolded and in a straight line. At this time, the adjacent sections are locked by the fixing mechanism: the adjusting block 23 drives the connecting insert plate 11 on the connecting section plate 4 to slide into the connecting slot 21. Under the traction of the flexible connecting cloth belt 10, the two adjacent connecting section plates 4 are pulled closer to each other. When the connecting insert plate 11 is fully inserted, the positioning insertion hole 24 at the bottom of the positioning post 12 moves exactly below the positioning post 12. The positioning post 12 is pushed out by the positioning spring 13 and quickly pops out and inserts into the positioning insertion hole 24, accompanied by a clear "click" sound, indicating that the connection has been reliably locked. At the same time, the limiting insert plate 8 is also inserted into the corresponding limiting slot 9, further ensuring the rigidity and stability of the structure after unfolding.

[0028] After all connecting plates 4 are unfolded and locked, the operator needs to connect adjacent irrigation spray booms 5 in series through connecting pipes 7. Tighten the connecting pipes 7, using their internal threads to engage with the external threads at both ends of the irrigation spray booms 5, to connect the spray boom sections into a complete long spray boom pipeline, ensuring a tight and leak-proof connection. The end of the last irrigation spray boom 5 is sealed with a sealing plug.

[0029] After mechanical assembly is completed, irrigation water and the required fertilizer can be injected into the irrigation tank 2 through the inlet pipe at the top. If stirring is required, the motor 18 can be started. The motor 18 drives the stirring rod and stirring blades 19 to rotate, so that the water and fertilizer are fully mixed evenly. After preparation, the water pump 14 is started. The water pump 14 draws liquid from the water tank through the bottom water pipe 16. The filter screen box 20 outside the water pipe 16 can effectively filter out any impurities that may be present, preventing blockage of the pipeline system. After the liquid is pressurized by the water pump 14, it is delivered to the irrigation spray bar 5 through the outlet hose 15, and finally sprayed evenly from multiple irrigation nozzles 6 arranged along the spray bar for large-scale irrigation.

[0030] After the work is completed, first turn off the water pump 14 and motor 18. Then, unscrew the connecting pipe 7 in sequence to separate each section of the irrigation spray bar 5. Next, for the fixing mechanism, press the exposed pressing ball 25 with your finger to push the positioning pin 12 back into the positioning slot to release the lock. Then, move the adjusting block 23 to slide the connecting plate 11 out of the connecting slot 21. After releasing all the fixing mechanisms, fold the connecting plates 4 of the folding bracket around the hinge points in sequence. Finally, place the entire bracket structure back into the storage frame 17 on the side of the irrigation tank 2 and fix it in place. It can then be easily transferred or stored.
