[0015] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0016] The first implementation method: Figure 1-4 and Figure 8 An irrigation device for soil and water conservation is shown, comprising a water supply pipe 1, the top end of which is connected to a rotating rod 2, and the water supply pipe 1 is rotatably connected to the rotating rod 2, the outer wall of the lower side of the rotating rod 2 is fixedly connected to a mounting box 6, the inner wall of the mounting box 6 located on one side of the rotating rod 2 is installed with an adjustment plate 13 that moves up and down, the inner wall of the mounting box 6 located on one side of the adjustment plate 13 is fixedly connected to a sliding sleeve 14, the inner wall of the sliding sleeve 14 is slidably connected to a horizontal rod 15, one end of the horizontal rod 15 is rotatably connected to a driven wheel 1501, the driven wheel 1501 is transmission-connected to the adjustment plate 13, the inner wall of the mounting box 6 located on one side of the sliding sleeve 14 is slidably connected to a toothed plate 16, and a tension spring 1 is fixedly connected between the bottom end of the toothed plate 16 and the inner wall of the mounting box 6 7. The inner wall of the installation box 6 located between the sliding sleeve 14 and the tooth plate 16 is rotatably connected with a pulley 18. A connecting rope 19 is fixedly connected between one end of the horizontal rod 15 away from the driven wheel 1501 and the top of the tooth plate 16. The connecting rope 19 and the pulley 18 are in transmission connection. The inner wall of the installation box 6 located on one side of the tooth plate 16 is rotatably connected with a linkage shaft 20. The outer wall of the linkage shaft 20 is fixedly connected with a gear 21 and a water outlet nozzle 22. The gear 21 is meshed with the tooth plate 16. A movable groove 601 is opened on the side wall of the installation box 6 near the water outlet nozzle 22. One end of the water outlet nozzle 22 passes through the movable groove 601 and extends to the outside of the installation box 6. An intermediate pipe 23 is fixedly connected between the top of the rotating rod 2 and one end of the water outlet nozzle 22. The adjustment plate 13 is set to be a curve with a slope gradually decreasing from left to right. When the adjustment plate 13 moves upward at a uniform speed, the horizontal rod 15 moves to the left and the moving speed of the horizontal rod 15 gradually increases. When the adjustment plate 13 moves downward at a uniform speed, the horizontal rod 15 moves to the right and the moving speed of the horizontal rod 15 gradually decreases.

[0017] When in use, the rotating rod 2 rotates, and water flows through the water supply pipe 1, the rotating rod 2, and the middle pipe 23 to the water outlet nozzle 22 and sprays outward. At the same time, the water outlet nozzle 22 swings up and down, so that the spraying trajectory of the water outlet nozzle 22 is spiral-shaped. Since the outer circle area of ​​the spiral is larger than the inner circle area, when the up and down swinging speed of the water outlet nozzle 22 is fixed and the water output of the water outlet nozzle 22 is fixed, it is bound to cause the irrigation amount of the inner circle of the spiral to be greater than the irrigation amount of the outer circle of the spiral.

[0018] Specifically, when the adjustment plate 13 moves upward uniformly, the horizontal rod 15 moves leftward and the moving speed of the horizontal rod 15 gradually increases. At the same time, the horizontal rod 15 drives the tooth plate 16 to move upward through the connecting rope 19 and the moving speed of the tooth plate 16 gradually increases. At the same time, the tooth plate 16 drives the water outlet nozzle 22 to swing downward clockwise through the gear 21 and the swinging speed gradually increases. In this process, the spraying time of the water outlet nozzle 22 in the inner circle of the spiral is reduced. Similarly, when the adjustment plate 13 moves downward uniformly, the water outlet nozzle 22 swings upward counterclockwise and the swing speed gradually slows down. In this process, the spraying time of the water outlet nozzle 22 on the spiral outer circle is increased; The above arrangement causes the spraying trajectory of the water outlet nozzle 22 to gradually slow down when it moves from the inner circle to the outer circle of the spiral, and to gradually speed up when it moves from the outer circle to the inner circle of the spiral. When the spraying amount and the rotation speed of the water outlet nozzle 22 are fixed, the spraying time at different positions of the inner and outer circles of the spiral can be adjusted, thereby compensating for the difference in irrigation amount between the inner and outer circles of the spiral, and making the vegetation at different positions more evenly irrigated.

[0019] The second implementation method: Figure 1 and Figure 4-7An irrigation device for soil and water conservation is shown. Different from the first embodiment, a transmission shaft 7 is rotatably connected to the middle part of the rotating rod 2, one end of the transmission shaft 7 is located on the inner side of the rotating rod 2 and is fixedly connected to a driving fan blade 8, the other end of the transmission shaft 7 is located on the outer side of the rotating rod 2 and is fixedly connected to a turntable 9, and a top wheel 12 is rotatably connected to the edge of one side of the turntable 9, two guide rods 10 are fixedly connected between the inner walls of the top and bottom ends of the installation box 6, a lifting plate 11 is slidably connected between the two guide rods 10, the outer wall of the guide rod 10 is sleeved with a top spring 24, the top and bottom ends of the top spring 24 are fixedly connected to the inner wall of the installation box 6 and the lifting plate 11 respectively, one end of the lifting plate 11 is fixedly connected to the side wall of the adjustment plate 13, the end of the rotating rod 2 close to the transmission shaft 7 is arranged in a convex shape, and the transmission shaft 7 is located on one side of the center line of the rotating rod 2.

[0020] Through the above arrangement, when water flows through the rotating rod 2, it can drive the driving blades 8 to rotate. When the driving blades 8 rotate, the turntable 9 is driven to rotate through the transmission shaft 7. When the turntable 9 rotates, it drives the top wheel 12 to rotate. When the top wheel 12 rotates, it contacts the lifting plate 11 and cooperates with the guide rod 10 to drive the lifting plate 11 to move up and down at a uniform speed. When the lifting plate 11 moves up and down, it can drive the adjusting plate 13 to move up and down at a uniform speed.

[0021] A sleeve 3 is provided between the rotating rod 2 and the water supply pipe 1, the bottom end of the rotating rod 2 is sealed and rotatably connected to the sleeve 3, the water supply pipe 1 and the sleeve 3 are fixedly connected, a propeller 4 is fixedly connected to the middle of the bottom end of the rotating rod 2, and a plurality of evenly distributed through holes 5 are provided at the bottom end of the rotating rod 2 on one side of the propeller 4. Through the above arrangement, when water flows through the water supply pipe 1 and the through holes 5 into the interior of the rotating rod 2, the rotating rod 2 can be driven to rotate under the action of the propeller 4.

[0022] The vertical height between the top and bottom ends of the adjusting plate 13 is greater than the diameter of the rotating disk 9 .

[0023] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
