A spraying head is installed on the top of the spraying water pump. An installation groove is opened on one side of the water and fertilizer tank, and a first sealing ring is fixedly connected inside the installation groove. In use, the processing motor is started to rotate the connecting rod, which in turn causes the processing rod and the mixing block to rotate in different cavities inside the water and fertilizer tank, thereby agitating the water and the medicine and mixing the medicine with the water. Then, the spraying water pump is started to spray the mixed liquid from the spraying head to spray and irrigate the plants. During the spraying and irrigation process, the rotating processing rod and the mixing block can prevent the medicine from settling, thereby avoiding the impact on plant growth caused by the medicine settling.

[0004] However, in irrigation needs, different plants have different requirements for the mixing ratio of water and pesticides. This system does not have a corresponding adjustment structure, so it cannot effectively adjust the ratio of water and pesticides dynamically and lacks adaptability.

[0005] To address the aforementioned problems, a water and fertilizer integrated mixing and irrigation device is proposed to solve these issues. Utility Model Content

[0006] To address the problem of the inability to dynamically adjust the mixing ratio of water and pesticides, the purpose of this invention is to provide an integrated water and fertilizer mixing and irrigation device.

[0009] A venturi tube is threaded between the two connecting pipes. The venturi tube is narrow in the middle and thicker at both ends.

[0010] A shut-off valve is connected to the outer wall of the Venturi tube, and one end of the shut-off valve is connected to a liquid storage box. The shut-off valve controls the flow between the liquid storage box and the Venturi tube.

[0021] 1. This utility model, through the setting of the adjustment component, moves the cone by rotating the screw, thereby adjusting the gap between the outer wall of the cone and the inner wall of the Venturi tube, thus controlling the resistance of water flow. Fine-tuning the resistance results in increased resistance, decreased flow rate, reduced flow velocity at the throat of the Venturi tube, weakened negative pressure, and reduced fertilizer solution intake.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example

[0032] like Figures 1-5 As shown, this utility model provides a water and fertilizer integrated mixing and irrigation device, including a valve 1 and a mixing assembly 6. The two ends of the valve 1 are respectively connected to an inlet pipe 2 and an outlet pipe 3. The valve 1, the inlet pipe 2 and the outlet pipe 3 are on the same axis.

[0033] Connecting pipes 8 are inserted into the bottom of the inlet pipe 2 and the outlet pipe 3 respectively. A support frame 9 is fixedly connected to the outer wall of the connecting pipe 8 to provide support.

[0034] A venturi tube 11 is threaded between the two connecting pipes 8. The venturi tube 11 is narrow in the middle and thicker at both ends.

[0035] A shut-off valve 7 is connected to the outer wall of the venturi tube 11. One end of the shut-off valve 7 is connected to the liquid storage box 10. The shut-off valve 7 controls the flow between the liquid storage box 10 and the venturi tube 11.

[0036] An adjustment component 4 is installed at one end of the venturi tube 11. The adjustment component 4 is used to adjust the inlet water flow rate of the venturi tube 11.

[0037] The adjustment component 4 extends to the outside of the connecting pipe 8 through the connecting pipe 8;

[0038] A stirring assembly 6 is installed on the storage box 10, which is used to stir the fertilizer solution;

[0039] Another connecting pipe 8 is equipped with a conveying assembly 5, which is used to convey the mixture;

[0040] The purpose of this setup is to agitate the fertilizer solution within the storage box 10 using the stirring component 6, preventing sedimentation of the solution inside the storage box 10. After agitation, valve 1 is closed, and water flows through the first connecting pipe 8 to the venturi tube 11. When the water flows through the narrowing section of the venturi tube 11, the narrowing pipe diameter causes the flow velocity to increase. This increased fluid velocity leads to a decrease in pressure. At the throat of the venturi tube 11, the water velocity reaches its maximum, and the pressure drops to its minimum, creating a negative pressure zone. The on / off valve 7 is then opened, allowing the storage box 10 and the venturi tube 11 to connect. When the connection is established, the fertilizer solution is drawn into the pipe under the action of external atmospheric pressure, mixes with the high-speed water flow, and then slows down and restores pressure when passing through the diffuser section of the Venturi tube 11, eventually forming a uniform water-fertilizer mixture. By adjusting the regulating component 4, the resistance of the water flow is finely adjusted. When the resistance increases, the flow rate decreases, the flow velocity at the throat of the Venturi tube 11 decreases, the negative pressure intensity weakens, the amount of fertilizer solution drawn in decreases, the resistance decreases, the flow rate increases, the flow velocity at the throat of the Venturi tube 11 increases, the negative pressure intensity strengthens, and the amount of fertilizer solution drawn in increases.

[0041] Valve 1 includes valve body 101 and valve plate 102. The two ends of valve body 101 are connected to inlet pipe 2 and outlet pipe 3 respectively. Valve plate 102 is rotatably connected to the inner wall of valve body 101. The rotating shaft of valve plate 102 passes through the top and bottom of valve body 101. A handle is connected to the top of the rotating shaft of valve plate 102, and a driven gear 103 is connected to the bottom of the rotating shaft of valve plate 102.

[0042] The purpose of this design is to turn the handle to drive the valve plate 102 to switch the water inlet pipe 2 and the water outlet pipe 3 on and off.

[0043] The adjusting assembly 4 includes a screw 401 and a cone 402. The screw 401 passes through the connecting pipe 8 and is threaded. The cone 402 is fixedly connected to one end of the screw 401 and is located inside the venturi tube 11.

[0044] The purpose of this setting is, as follows: Figure 3 As shown, by rotating the screw 401, the cone 402 is moved, thereby adjusting the gap between the outer wall of the cone 402 and the inner wall of the venturi tube 11, thereby controlling the resistance of water flow.

[0045] The on / off valve 7 includes a valve tube 701 and a valve core 702. The valve tube 701 is connected between the liquid storage box 10 and the venturi tube 11. The valve core 702 is slidably connected to the inner wall of the valve tube 701. A connecting rod is fixedly connected to the outer wall of the valve core 702. The connecting rod passes through the valve tube 701 and is slidably connected.

[0046] The purpose of this design is to allow the valve core 702 to slide when the connecting rod is pulled, such as... Figure 5 As shown, the solution passing through valve tube 701 is switched on and off.

[0047] The stirring assembly 6 includes a drive motor 601, a U-shaped bracket is fixedly connected to the top of the liquid storage box 10, the drive motor 601 is mounted on the upper surface of the U-shaped bracket, and a drive gear 602 and a stirring rod 603 are fixedly connected to the output shaft of the drive motor 601. The drive gear 602 and the driven gear 103 mesh with each other.

[0048] The purpose of this setting is, as follows: Figure 4 As shown, the output shaft of the drive motor 601 drives the drive gear 602 and the stirring rod 603 to rotate. The rotation of the stirring rod 603 prevents the fertilizer solution inside the storage box 10 from settling, and at the same time facilitates mixing with the fertilizer solution added earlier, reducing the concentration difference between solutions added one after the other.

[0049] The conveying assembly 5 includes a micro motor 501 and a screw rod 502. The micro motor 501 is mounted on the outer wall of the connecting pipe 8, and the output shaft of the micro motor 501 extends into the interior of the connecting pipe 8. The screw rod 502 is mounted on the outer wall of the output shaft of the micro motor 501.

[0050] The purpose of this setting is, as follows: Figure 2 As shown, the output shaft of the micro motor 501 drives the screw rod 502 to rotate, which speeds up the delivery of the mixture and prevents sedimentation inside the connecting pipe 8. The screw rod 502 fits against the inner wall of the connecting pipe 8, and the rotation process facilitates the cleaning of the connecting pipe 8.

[0051] Working principle: The output shaft of the drive motor 601 drives the drive gear 602 and the stirring rod 603 to rotate. The rotation of the stirring rod 603 prevents the fertilizer solution inside the storage box 10 from settling and also facilitates mixing with the fertilizer solution added earlier, reducing the concentration difference between the solutions added one after the other. The gear ratio between the drive gear 602 and the driven gear 103 is 1:4. For example, when the drive gear 602 and the stirring rod 603 rotate one full circle (360 degrees), the driven gear 103 rotates half a circle (90 degrees), thereby driving the valve plate 102 to seal the inlet pipe 2 and the outlet pipe 3.

[0052] When water flows through the constriction section of the Venturi tube 11, the narrowing of the tube diameter causes the flow velocity to increase. The increased fluid velocity leads to a decrease in pressure. At the throat of the Venturi tube 11, the water velocity reaches its maximum value, and the pressure drops to its minimum, forming a negative pressure zone. At the same time, the connecting rod is pulled to drive the valve core 702 to slide, connecting the solution passing through the valve tube 701 and connecting the liquid storage box 10 with the Venturi tube 11. At this time, the fertilizer solution is drawn into the tube under the action of external atmospheric pressure and mixed with the high-speed water flow. When it passes through the diffusion section of the Venturi tube 11, the flow velocity slows down and the pressure recovers, finally forming a uniform water-fertilizer mixture. By rotating the screw 401, the cone 402 is moved, thereby adjusting the gap between the outer wall of the cone 402 and the inner wall of the Venturi tube 11, thereby controlling the resistance of water flow.

[0053] By fine-tuning the resistance of water flow, the flow rate decreases as the resistance increases, the flow velocity at the throat of the Venturi tube 11 decreases, the negative pressure intensity weakens, and the amount of fertilizer solution absorbed decreases. Conversely, by increasing the flow rate at the throat of the Venturi tube 11, the flow velocity increases, the negative pressure intensity strengthens, and the amount of fertilizer solution absorbed increases. This allows for adjustments to the mixing amount of different fertilizer solutions to meet different needs.

[0054] The output shaft of the micro motor 501 drives the screw rod 502 to rotate, which speeds up the delivery of the mixture and prevents sedimentation inside the connecting pipe 8. The screw rod 502 fits against the inner wall of the connecting pipe 8, and the rotation process facilitates the cleaning of the connecting pipe 8.

The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0056] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
