[0004] However, in the process of irrigating crops, due to the influence of the crop planting range and planting terrain, during irrigation, crops that are far away from the irrigation device require greater pressure to push water and fertilizer for spraying irrigation, which can easily cause crops that are closer to the irrigation device to be washed by high-pressure water flow, which may cause the roots, stems and leaves of the crops to be damaged by the high-pressure water flow. In addition, the high-speed sprayed water flow has a greater force on the soil closer to the irrigation device, which may cause soil erosion and further cause the crops to wither and die.

[0005] In order to solve the above problems, the present application proposes a lifting type water-fertilizer integrated irrigation head device. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1 , Figure 2A lifting type water-fertilizer integrated irrigation head device comprises a base 1, the inner side wall of the base 1 is slidably connected with a water tank 2, the outer side wall of the water tank 2 is fixedly connected with a threaded sleeve 3, the outer side wall of the base 1 is fixedly connected with a shell 4, the shell 4 is located on a side of the water tank 2 close to the threaded sleeve 3, the shell 4 is located below the threaded sleeve 3, the inner bottom of the shell 4 is rotatably connected with a first threaded rod 5, the outer side wall of the first threaded rod 5 is fixedly connected with a first gear 6, the first gear 6 is located inside the shell 4, the outer side wall of the first threaded rod 5 is threadedly connected with the inner side wall of the threaded sleeve 3, the inner bottom of the shell 4 is rotatably connected with a second threaded rod 7, and the outer side wall of the second threaded rod 7 is fixedly connected with a second gear 8, The first gear 6 and the second gear 8 are on the same horizontal plane, the outer wall of the first gear 6 is meshed with the outer wall of the second gear 8, the outer wall of the second threaded rod 7 is threadedly connected with a nozzle seat 9, and the nozzle seat 9 is located at the top of the outer shell 4, the inner bottom of the base 1 is fixedly connected with a support frame 10, the inner bottom of the base 1 is fixedly connected with a spring 11, and the end of the spring 11 away from the inner wall of the base 1 is fixedly connected to the bottom of the water tank 2, the support frame 10, the spring 11 and the center point of the water tank 2 are on the same vertical line, the inner bottom of the base 1 is fixedly connected with a water pump, the water inlet of the water pump is fixedly connected to the bottom of the water tank 2 through a hose, and the water outlet of the water pump is fixedly connected to the bottom of the nozzle seat 9 through a hose.

[0024] Add the mixed water and fertilizer that need to be irrigated into the water tank 2. When the water tank 2 is added with raw materials, it moves downward under the influence of gravity. At this time, the water tank 2 compresses the spring 11. Since the threaded sleeve 3 is fixedly connected to the water tank 2, and the threaded sleeve 3 is threadedly connected to the first threaded rod 5, the water tank 2 drives the threaded sleeve 3 to move synchronously toward the bottom direction of the base 1, which will drive the first threaded rod 5 to rotate. Since the first threaded rod 5 is fixedly connected to the first gear 6, and the first gear 6 is meshed with the second gear 8, and since the second gear 8 is fixedly connected to the second threaded rod 7, when the first gear 6 rotates, it further drives the second gear 8 to rotate in the opposite direction. Since the second threaded rod 7 is threadedly connected to the nozzle seat 9, when the second threaded rod 7 rotates, the nozzle seat 9 will move toward the top of the second threaded rod 7. When the nozzle on the top of the nozzle seat 9 is used to spray irrigation to the outside, the water and fertilizer solution inside the water tank 2 is reduced, which reduces the weight of the water tank 2. Under the action of the elastic force of the spring 11 itself, the water tank 2 moves toward the top of the base 1, thereby driving the first threaded rod 5 to rotate in the opposite direction, and then through the transmission of the first gear 6, the shell 4, and the second gear 8, the nozzle seat 9 moves toward the bottom of the second threaded rod 7, thereby realizing the lifting and lowering of the nozzle on the top of the nozzle seat 9.

[0025] Reference Figure 3A protective sleeve 12 is fixedly connected to the top of the shell 4, a rotating rod 15 is fixedly connected to the inner wall of the protective sleeve 12, a protective cover 13 is rotatably connected to the outer wall of the rotating rod 15, a pull rod 14 is rotatably connected to the bottom of the protective cover 13, and one end of the pull rod 14 away from the bottom of the protective cover 13 is rotatably connected to the bottom of the nozzle seat 9.

[0026] When in use, the nozzle seat 9 moves upward. Since the bottom of the nozzle seat 9 is rotated and connected to the pull rod 14, the nozzle seat 9 will drive the pull rod 14 to move synchronously at one end close to the nozzle seat 9 during the movement. The pull rod 14 is rotated away from the bottom of the nozzle seat 9 at one end to connect the bottom of the protective cover 13. Since the protective cover 13 is rotationally connected to the rotating rod 15, the pull rod 14 will drive the part of the protective cover 13 located below the rotating rod 15 to gradually move toward the inside of the protective cover 12 when following the synchronous movement of the nozzle seat 9, so that the part of the protective cover 13 located above the rotating rod 15 gradually moves away from the protective cover 12. The rotating rod 15 is fixedly connected to the protective cover 12, and the protective cover 12 is fixedly connected to the outer shell 4. Therefore, when the nozzle seat 9 moves upward, the pull rod 14 connected at the bottom drives the protective cover 13 to rotate, so that the protective cover 13 is automatically opened and closed.

[0027] Reference Figure 3 The top of the shell 4 is fixedly connected to a fixing rod 19. Two fixing rods 19 are provided, which are respectively located on the inner walls on both sides of the protective cover 12. The outer walls of the fixing rods 19 are respectively slidably connected to the nozzle seat 9. When the nozzle seat 9 moves, the fixing rods 19 can prevent the nozzle seat 9 from shifting in position and limit the horizontal position of the nozzle seat 9.

[0028] Reference Figure 4 The outer wall of the water tank 2 is fixedly connected with a block 18, and the inner wall of the base 1 is provided with a sliding groove 20. There are two blocks 18 and two sliding grooves 20. The two blocks 18 are respectively located on the outer walls of the water tank 2 on both sides, and the two sliding grooves 20 are respectively located on the inner walls of the base 1 on both sides. The outer walls of the two blocks 18 are respectively slidably connected with the inner walls of the two sliding grooves 20. When the water tank 2 moves up and down, the combination of the block 18 and the sliding groove 20 can prevent the angle of the water tank 2 from tilting.

[0029] Reference Figure 4 A baffle 16 is hinged on the top of the water tank 2, and a rubber ring 21 is fixedly connected to the inner wall of the baffle 16. A handle is installed on the top of the baffle 16 to facilitate workers to open and close the water tank 2. The rubber ring 21 is convenient for reducing the force generated by the collision between the baffle 16 and the water tank 2, thereby avoiding damage to the baffle 16 during frequent use and increasing the service life of the baffle 16.

[0030] Reference Figure 2 , Figure 4A protrusion 22 is fixedly connected to the inside of the water tank 2, and a screen 17 is arranged on the top of the protrusion 22. A filtering hole is opened through the top of the screen 17 to prevent fallen leaves and other debris from falling into the water tank 2 and clogging the drain pipe when the worker opens the baffle 16 to collect rainwater.

[0031] Working principle:

[0032] During use, the irrigation staff opens the water tank 2 by the handle and adds the water and fertilizer that need to be irrigated and mixed into the water tank 2. When the water tank 2 is added with raw materials, it moves downward under the influence of gravity. At this time, the water tank 2 compresses the spring 11, and the water tank 2 drives the threaded sleeve 3 to move synchronously toward the bottom direction of the base 1, which will drive the first threaded rod 5 to rotate, and the first threaded rod 5 will drive the first gear 6 to rotate. Therefore, when the first gear 6 rotates, it further drives the second gear 8 to rotate in the opposite direction, and the second gear 8 will drive the second threaded rod 7 to rotate synchronously. Therefore, when the second threaded rod 7 rotates, it will make the nozzle seat 9 move toward the top direction of the second threaded rod 7. During the movement, the nozzle seat 9 will drive the pull rod 14 to move synchronously at one end close to the nozzle seat 9. When the pull rod 14 moves synchronously with the nozzle seat 9, it will drive the anti-fouling device 12 to rotate synchronously. The part of the protective cover 13 located below the rotating rod 15 gradually moves toward the inside of the protective sleeve 12, so that the part of the protective cover 13 located above the rotating rod 15 gradually moves away from the protective sleeve 12. When the nozzle seat 9 moves upward, the pull rod 14 connected at the bottom drives the protective cover 13 to rotate, so that the protective cover 13 is automatically opened. At this time, the water pump is started. When the nozzle on the top of the nozzle seat 9 is used to spray irrigation to the outside, the internal water and fertilizer solution of the water tank 2 is reduced, so that the weight of the water tank 2 is reduced. Under the action of the elastic force of the spring 11 itself, the water tank 2 moves toward the top of the base 1, thereby driving the first threaded rod 5 to rotate in the opposite direction, and then through the transmission of the first gear 6, the outer shell 4, and the second gear 8, the nozzle seat 9 moves toward the bottom direction of the second threaded rod 7, so that the nozzle on the top of the nozzle seat 9 is lifted and lowered.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
