With the continuous injection of liquid, the rotating tube 31 at the top of the movable tube 29 is pushed upward by the upward thrust of the liquid, so that the spray holes 34 in the middle of the side wall of the rotating tube 31 are exposed, and the liquid is sprayed along the spray holes 34, so that the rotating tube 31 is pushed in the tangential direction, and the rotating tube 31 is pushed to start rotating, so that the irrigation of crops is more uniform.

[0024] A top block 30 is fixedly provided on the top of the rotating tube 31, and the top block 30 is set in a cone shape.

The telescopic guide rod 39 is perpendicular to the inner wall of the outer cylinder 22, and a second return spring 38 is arranged around the outside of the telescopic guide rod 39. When the movable tube 29 moves upward, it drives the rotating tube 31 and the top block 30 to move upward until the top block 30 is stuck in the groove 36 at the bottom of the movable block 35, generating an outward thrust on the movable block 35, pushing the movable block 35 to slide to the outside of the movable groove 37.

[0025] The flow regulating mechanism 24 includes a rotating ring 33, which is rotatably connected to the end face of the output end of the liquid outlet pipe 85. A liquid outlet hole is opened in the center of the liquid outlet pipe 85. The rotating ring 33 is coaxially arranged with the liquid outlet pipe 85. The output end of the liquid outlet pipe 85 is arranged perpendicular to the axis of the fixed pipe 25. A movable rod 28 is fixedly arranged at the bottom of the movable tube 29. The movable rod 28 is arranged parallel to the axis of the fixed pipe 25. The movable rod 28 is arranged tangent to the edge of the rotating ring 33. A plurality of latch teeth 45 are arranged at the connection between the side wall of the movable rod 28 facing the rotating ring 33 and the outer wall of the rotating ring 33. The spacing between adjacent latch teeth 45 is consistent. The movable rod 28 and the rotating ring 33 are meshed through the latch teeth 45. When the flow rate is large, the water pressure on the movable tube 29 is large, and the height of the upward movement is higher. At this time, the movable rod 28 moves upward for a longer distance, and the rotating ring 33 engaged with it through the latching teeth 45 rotates at a larger angle. On the contrary, when the flow rate is small, the rotating ring 33 rotates at a smaller angle.

[0026] A plurality of connecting shafts 41 are evenly arranged around the liquid outlet hole on the output end face of the liquid outlet pipe 85, and the connecting shaft 41 is perpendicularly arranged to the output end face of the liquid outlet pipe 85.

When the flow rate is too large, the larger the angle of rotation of the rotating ring 33, the larger the amplitude of rotation of the baffle 42, so that the flow area of ​​the liquid outlet 18 is smaller, and the flow rate of the liquid outlet pipe 85 is reduced. When the flow rate is too small, the smaller the angle of rotation of the rotating ring 33, the smaller the amplitude of rotation of the baffle 42, so that the flow area of ​​the liquid outlet 18 is larger, and the flow rate of the liquid outlet pipe 85 is increased, so that the water pressure inside the movable pipe 29 remains stable, and the irrigation amount of the crop per unit time remains stable, avoiding excessive irrigation or insufficient irrigation.

[0027] The number of the connecting shafts 41 matches the number of the blocking pieces 42 .

[0028] The stirring mechanism includes a movable plate 14, a liquid storage chamber 13 is provided inside the liquid storage tank 1, and the movable plate 14 is horizontally arranged in the middle of the liquid storage chamber 13. The left rotating rod 19 and the right rotating rod 15 are respectively and symmetrically arranged on both sides of the liquid storage tank 1. The left rotating rod 19 and the right rotating rod 15 both vertically penetrate the movable plate 14. The connection between the left rotating rod 19 and the movable plate 14 is provided with a left threaded portion 20, and the left rotating rod 19 is threadedly connected to the movable plate 14 through the left threaded portion 20. The connection between the right rotating rod 15 and the movable plate 14 is provided with a right threaded portion 16, and the right rotating rod 15 is threadedly connected to the movable plate 14 through the right threaded portion 16. When the water-fertilizer solution is injected, the falling solution generates a downward impact force on the movable plate 14, causing the movable plate 14 to move downward, driving the left rotating rod 19 threadedly connected to it through the left threaded portion 20 to start rotating, and the right rotating rod 15 rotates in the opposite direction.

[0029] A plurality of left stirring rods 21 are vertically arranged on the outer side wall of the bottom of the left rotating rod 19, and a plurality of right stirring rods 17 are vertically arranged on the outer side wall of the bottom of the right rotating rod 15, and the left stirring rods 21 and the right stirring rods 17 are arranged alternately. When the left rotating rod 19 rotates, the left stirring rod 21 at the bottom is driven to rotate, and the water-fertilizer solution is stirred, so that the fertilizer and water are mixed more thoroughly. When the right rotating rod 15 rotates, the right stirring rod 17 is driven to rotate, which has a disturbing effect on the solution and improves the stirring effect.

[0030] The movable plate 14 and the top of the liquid storage chamber 13 are connected with a third return spring, which surrounds the outside of the left rotating rod 19 and the right rotating rod 15. When the movable plate 14 moves downward, the third return spring stretches, generating an upward pulling force, so that the movable plate 14 reciprocates up and down under the action of the pulling force and the impact force, further improving the stirring effect.

[0031] Working principle: When in use, water-fertilizer solution is injected into the liquid storage tank 1 through the liquid injection port 4. During injection, the water-fertilizer solution can be automatically stirred by the stirring mechanism inside the liquid storage tank 1, so that the water-fertilizer mixture is more uniform and the irrigation effect is improved. After the mixing is completed, the liquid pump 3 is started to extract the water-fertilizer solution through the liquid outlet pipe 85, and then pumped out to the liquid distribution pipe 7 through the liquid outlet pipe 85. At this time, the valve 9 of the liquid outlet pipe 85 of the area to be irrigated is opened, so that the water-fertilizer solution flows into the irrigation mechanism 11 of the area to irrigate the crops. The flow regulating mechanism 24 can keep the amount of solution sprayed during irrigation stable to avoid excessive irrigation or insufficient irrigation. When the irrigation machine is not in use The structure 11 can be retracted by itself to protect it; when the water-fertilizer solution is injected, the falling solution generates a downward impact force on the movable plate 14, causing the movable plate 14 to move downward, driving the left rotating rod 19 threadedly connected thereto through the left threaded portion 20 to start rotating, and at the same time, the right rotating rod 15 rotates in the opposite direction. When the left rotating rod 19 rotates, it drives the left stirring rod 21 at the bottom to start rotating, stirring the water-fertilizer solution, so that the fertilizer and water are mixed more thoroughly. When the right rotating rod 15 rotates, it drives the right stirring rod 17 to start rotating, which has a disturbing effect on the solution and improves the stirring effect. When the movable plate 14 moves downward, the third reset spring stretches, generating an upward pulling force, so that the movable plate 1 4 makes up-and-down reciprocating motion under the action of pulling force and impact force, further improving the stirring effect; during irrigation, the liquid flows into the fixed tube 25 along the liquid outlet pipe 85, pushing the movable tube 29 to move upward, at which time the first return spring 27 is compressed, generating elastic force in the opposite direction, and as the liquid is continuously injected, the rotating tube 31 at the top of the movable tube 29 is pushed upward by the upward thrust of the liquid, so that the spray hole 34 in the middle of the side wall of the rotating tube 31 is exposed, and the liquid is sprayed along the spray hole 34, so that the rotating tube 31 is pushed in the tangential direction, pushing the rotating tube 31 to start rotating, so that the irrigation of the crop is more uniform, and when the movable tube 29 moves upward, it drives the rotating tube 31 and the top block 30 to move upward until the top block 30 is moved upward. The block 30 is inserted into the groove 36 at the bottom of the movable block 35, generating an outward thrust on the movable block 35, pushing the movable block 35 to slide to the outside of the movable groove 37. At this time, the telescopic guide rod 39 is shortened, and the second return spring 38 is compressed, generating an elastic force in the opposite direction, until the movable tube 29 protrudes out of the outer tube 22 under the action of water pressure, and the crops are irrigated. When the irrigation is completed, the water pressure in the movable tube 29 is reduced, and the movable tube 29 is reset under the elastic force of the first return spring 27 and retracted into the inner part of the outer tube 22 again. At this time, the movable block 35 is reset under the elastic force of the second return spring 38, and the top of the outer tube 22 is sealed to protect the movable tube 29 and the fixed tube 25;When the flow rate is large, the water pressure on the movable tube 29 is large, and the higher the height of the upward movement, the farther the movable rod 28 moves upward, and the larger the angle of rotation of the rotating ring 33 engaged with it through the latching teeth 45. On the contrary, when the flow rate is small, the smaller the angle of rotation of the rotating ring 33 is. When the rotating ring 33 rotates, the driving teeth 44 on its inner wall are driven to move accordingly, so that the driven teeth 43 engaged with the driving teeth 44 rotate in the same direction, driving the baffle 42 to start rotating, and the liquid outlet 18 is closed. When the flow rate is too large, the larger the angle of rotation of the rotating ring 33, the larger the amplitude of rotation of the baffle 42, so that the flow area of ​​the liquid outlet 18 is smaller, and the flow rate of the liquid outlet pipe 85 is reduced. When the flow rate is too small, the smaller the angle of rotation of the rotating ring 33, the smaller the amplitude of rotation of the baffle 42, so that the flow area of ​​the liquid outlet 18 is larger, and the flow rate of the liquid outlet pipe 85 is increased, so that the water pressure inside the movable tube 29 is kept stable, and the irrigation amount of the crop is kept stable per unit time, avoiding excessive irrigation or insufficient irrigation. ;
