The first movable rod 11 is hinged to the connecting seat on the inner wall of one end of the first support frame 5, and the second movable rod 12 is hinged to the connecting seat on the inner wall of one end of the second support frame 6. The other end of the electric telescopic rod 9 is hinged to the fixed seat on the first support frame 5. More specifically, driving the electric telescopic rod 9 to extend and retract moves the first movable rod 11 and the second movable rod 12 in conjunction with the connecting block 10, thereby pushing the second support frame 6 and causing the rotating plate 8 connected to one end of it to rotate around the pin shaft, thereby realizing the angle adjustment between the first support frame 5 and the second support frame 6, and thus changing the irrigation coverage area.

[0030] refer to Figure 7 The protective components include a first protective cover 16 and a second protective cover 17 installed at the bottom of the first support frame 5 and the second support frame 6. Symmetrical movable seats 18 are installed at the middle position of the top of the first protective cover 16 and the second protective cover 17. Symmetrical sliders 19 are also installed at the two end edges of the top of the first protective cover 16 and the second protective cover 17.

The other end of the bidirectional lead screw 22 is connected to a bearing seat installed on another fixing block 20. A sliding rod 23 is fixedly connected between the two sets of fixed blocks 20. The sliding rod 23 passes through the slider 19 and slides with it. More specifically, the first servo motor 21 is started to drive the bidirectional lead screw 22 to rotate. Through the threaded engagement, the movable seat 18 moves along the bidirectional lead screw 22 in opposite directions or in opposite directions, thereby pushing the first protective cover 16 and the second protective cover 17 to slide synchronously on the sliding rod 23 to achieve opening and closing adjustment. When the sprinkler is in operation, the first protective cover 16 and the second protective cover 17 are opened to expose the sprinkler head 15 for normal irrigation. When the operation is stopped or in bad weather, the first protective cover 16 and the second protective cover 17 are closed to effectively block external dust, rainwater and debris, protect the internal mechanical structure and sprinkler device, extend the service life of the equipment, and reduce the maintenance frequency.

[0031] refer to Figure 3The adjustment mechanism includes first mounting bases 24 installed on the top of the fixed frame 4 near both ends. A second servo motor 25 is fixedly mounted on one side of one of the first mounting bases 24. The output end of the second servo motor 25 is connected to a double-headed worm gear 26. One end of the double-headed worm gear 26 passes through a through hole in a support block on the top of the fixed frame 4 and is connected to a bearing seat installed on the other first mounting base 24. A rotating shaft 27 is rotatably mounted in the shaft holes at both ends of the fixed frame 4. One end of the rotating shaft 27 extends out of the fixed frame 4 and is fixedly mounted with a worm gear 28. The worm gear 28 and...

The other end of the rotating seat 29 passes through the openings at both ends of the fixed frame 4 and is connected to one end of the first support frame 5. More specifically, the second servo motor 25 is started to drive the double-headed worm gears 26 to rotate. Through the meshing transmission between the worm wheel 28 and the double-headed worm gears 26, the rotating shaft 27 and the rotating seat 29 fixed thereon are driven to rotate synchronously, thereby realizing the overall horizontal rotation adjustment of the first support frame 5 and the second support frame 6, expanding the sprinkler coverage angle, and improving irrigation flexibility and operation efficiency.

[0032] refer to Figure 2 The lifting mechanism includes a second mounting base 30 installed on the fixed column 2. A third servo motor 31 is fixedly installed on one side of the second mounting base 30. The output end of the third servo motor 31 is connected to a transmission shaft 32. The transmission shaft 32 passes through the second mounting base 30, and one end is connected to a bearing seat installed on one of the second mounting bases 30. Symmetrical gears 33 are also installed on the transmission shaft 32. The gears 33 mesh with the rack plate 34 inside the opening on the side wall of the fixed column 2. The rack plate 34 is fixedly installed on one side of the support column 3. More specifically, when the third servo motor 31 is started, it drives the transmission shaft 32 to rotate, which drives the gears 33 installed at both ends to rotate synchronously. Through the meshing transmission of the gears 33 and the rack plate 34, the support column 3 is driven to rise and fall vertically along the sliding groove opened on the inner wall of the fixed column 2, so that the height of the fixed frame 4 can be adjusted. This allows for the adjustment of the overall height of the first support frame 5 and the second support frame 6, adapting to the irrigation needs of different crop growth stages, improving irrigation accuracy and coverage, and ensuring efficient use of water resources.

[0033] refer to Figure 1 , Figure 7 and Figure 8The sprinkler system includes a water tank 35 mounted on the top of a mobile cart 1. A water outlet pipe is installed on one side of the water tank 35. One end of the outlet pipe is connected to a water pump mounted on the side wall of the water tank 35, and the other end is connected to two identical water delivery hoses 14. The water delivery hoses 14 are U-shaped and distributed at the bottom of the first support frame 5 and the second support frame 6, and are fixedly mounted on mounting rings 13 at the bottom of the first support frame 5 and the second support frame 6. The bottom end of the water delivery hoses 14 is also connected to a diversion pipe for diversion. Multiple nozzles 15 are evenly connected to the bottom of the pipe. An inlet is installed at the top of the water storage tank 35. A filter tank is also provided inside the water storage tank 35, and a filter frame 36 is installed inside the filter tank. The filter frame 36 is filled with an activated carbon filter element. Symmetrical fixing holes 37 are provided at both ends of the filter frame 36. Symmetrical L-shaped support plates 38 are also installed on the side walls of both ends of the water storage tank 35. A pull rod 39 is installed in the through hole on the L-shaped support plate 38. One end of the pull rod 39 is connected to a fixing socket 40. A spring 41 is connected to one side of the pull rod 39, and the spring 41 is sleeved on the outside of the pull rod 39, with one end abutting against the L-shaped support plate 38. The other end of the fixing socket 40 is engaged with the fixing hole 37 on the filter frame 36. More specifically, by pulling the pull rod 39, the fixing socket 40 is retracted and disengaged from the fixing hole 37, allowing the filter frame 36 to be removed from the filter tank for cleaning or replacement, ensuring water quality and preventing the nozzle 15 from clogging. When sprinkler irrigation is in progress, the water pump operates to pump water from the water storage tank 35 through the outlet pipe. Water is delivered to each sprinkler head 15 via the hose 14 and the distribution pipe. Spraying is carried out through the sprinkler head 15, forming uniform atomized water droplets that cover the crop canopy, effectively increasing field humidity and reducing water evaporation loss. When water is added to the water storage tank 35, the water flows through the inlet into the filter tank, where impurities and particulate matter are effectively adsorbed and filtered by the activated carbon filter element, ensuring clean water storage, extending the service life of the sprinkler irrigation system, and preventing the sprinkler head 15 from clogging or leaking due to water quality issues, thus ensuring continuous and stable operation of irrigation.

[0034] The implementation principle of a water-saving sprinkler irrigation device for agriculture according to an embodiment of the present invention is as follows: During use, a mobile cart 1 is driven to travel along the field to the target irrigation area. The second servo motor 25 is activated, driving the double-headed worm gear 26 to rotate. Through the meshing transmission between the worm wheel 28 and the double-headed worm gear 26, the rotating shaft 27 and the rotating seat 29 fixed thereon rotate synchronously, thereby achieving horizontal rotation adjustment of the first support frame 5 and the second support frame 6. Then, the electric telescopic rod 9 is driven to extend and retract, driving the first movable rod 11 and the second movable rod 12 in conjunction through the connecting block 10, thereby pushing the second support frame 6 so that the rotating plate 8 connected to one end rotates around the pin shaft, achieving angle adjustment between the first support frame 5 and the second support frame 6, and thus adjusting the spray angle of the sprinkler head 15, achieving flexible control of the irrigation range to meet the needs of different crop growth stages for irrigation angle and coverage radius. Simultaneously, the third servo motor 31 is activated, driving the transmission shaft 32 to rotate, driving the gears 33 installed at both ends to rotate synchronously, through the gears... The meshing transmission between wheel 33 and rack plate 34 drives support column 3 to vertically rise and fall along the sliding groove opened on the inner wall of fixed column 2, thereby adjusting the height of fixed frame 4 and thus realizing the overall height adjustment of first support frame 5 and second support frame 6. This adapts to the sprinkler irrigation needs of different crop growth stages, improves irrigation accuracy and coverage, and ensures efficient use of water resources. When sprinkler irrigation is carried out, the water pump works to transport water in water storage tank 35 through water outlet pipe, water delivery hose 14 and diversion pipe to each nozzle 15. Spraying is carried out through nozzle 15 to form uniform atomized water droplets covering the crop canopy, effectively increasing field humidity and reducing water evaporation loss. When water is added to water storage tank 35, the water flows through the inlet into the filter tank. The activated carbon filter element effectively adsorbs and filters impurities and particulate matter to ensure clean water. By pulling the lever 39, the fixed socket 40 retracts and disengages from the fixed hole 37, and the filter frame 36 can be removed from the filter tank for cleaning or replacement to ensure water quality and prevent nozzle 15 from clogging.

[0035] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
