Description

Technical Field

[0001] This utility model relates to the field of irrigation technology, specifically to an integrated water and fertilizer drip irrigation device. Background Technology

[0002] Drip irrigation is an advanced agricultural irrigation method that supplies water through drip tape (or drip pipe) placed at the base of crops. The drip tape has many small outlets, from which water slowly moistens the soil around the crop roots. Because the area of ​​moisture wetting is controllable, drip irrigation is currently the most effective water-saving irrigation method. In addition to saving water, it also reduces fertilizer loss and promotes crop growth.

[0003] Patent document CN221152015U discloses an integrated water and fertilizer drip irrigation device for organic tea cultivation. It includes a water-fertilizer mixing cylinder for mixing water and fertilizer for organic tea cultivation, and a water-fertilizer delivery pipe installed on the outer wall of the mixing cylinder. Several sets of evenly spaced adjustable drip irrigation mechanisms are installed on the water-fertilizer delivery pipe. Each adjustable drip irrigation mechanism includes a retractable corrugated pipe and an externally threaded connector threaded to the outer wall of the water-fertilizer delivery pipe. An internally threaded groove is provided at the end of the corrugated pipe away from the externally threaded connector, and a detachable drip irrigation head is installed on the internally threaded groove. An installation head threaded to the internally threaded groove is installed on the drip irrigation head, and a fixing pin inserted into the soil is installed on the outer wall of the corrugated pipe near the drip irrigation head. This technical solution offers high flexibility in the drip irrigation head, allowing it to be easily positioned close to the plants requiring irrigation. However, this also allows water to flow directly from the drip head to the ground. Due to water evaporation during irrigation, some water is wasted. When drip irrigation is used for mixed planting, it is not convenient to adjust the irrigation speed according to different irrigation subjects. Utility Model Content

[0004] The main purpose of this utility model is to provide a water and fertilizer integrated drip irrigation device that can reduce water evaporation during irrigation and adjust the irrigation speed according to soil type and irrigation subject.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A water and fertilizer integrated drip irrigation device includes a water and fertilizer mixing device. One end of the outlet pipe of the water and fertilizer mixing device is connected to a flexible hose, and the other end of the flexible hose is connected to a main pipe. The other end of the main pipe is sealed. Multiple branch pipes are evenly distributed and fixedly connected to both sides of the main pipe along its length. Each branch pipe is fixedly connected to one end of a corrugated pipe, and the other end of the corrugated pipe is connected to a side pipe. The side pipe is fixedly connected to a drip irrigation head. The drip irrigation head includes an insert tube, the lower end of which is sealed and pointed. Multiple external holes are evenly distributed around the side wall of the insert tube, and a rotating sealing connection is formed inside the insert tube. It has an inner tube, a side tube and an insertion tube section above the inner tube that are fixedly connected. The upper end of the inner tube is open and the lower end is sealed. The outer edge of the inner tube is rotatably and sealingly connected to the inner edge of the insertion tube. An inner hole corresponding to the outer hole is opened on the side wall of the inner tube. An end cap is threaded and sealed to the upper end of the insertion tube. An inner rod is concentrically arranged inside the inner tube. The lower end of the inner rod is fixedly connected to the lower end of the inner tube. The upper end of the inner rod passes through a perforation on the end cap. The inner rod and the perforation are rotatably and sealingly connected. A retaining ring is fixed on the inner rod below the end cap. The upper end face of the retaining ring contacts the lower end face of the end cap.

[0007] Specifically, sealing rings are fixedly fitted on the upper and lower ends of the outer side of the inner tube, and the inner tube is rotatably and sealingly connected to the insertion tube through the sealing rings.

[0008] Specifically, a sealing ring is fixedly and sealed inside the perforation of the end cap, and an inner rod passes through the sealing ring, with the inner rod being rotatably and sealingly connected to the end cap through the sealing ring.

[0009] Specifically, the side tube is perpendicular to the insertion tube.

[0010] Specifically, the water-fertilizer mixing equipment includes a cylinder with an opening at the top and a cover plate installed at the top. A support ring is concentrically fixed at the bottom of the cylinder, and a motor is concentrically fixed at the bottom of the cylinder inside the support ring. A stirring rod is concentrically rotatably connected inside the cylinder. The output shaft of the motor is concentrically fixedly connected to the bottom of the stirring rod. A submersible pump is fixed inside the cylinder on one side of the stirring rod. The outlet end of the submersible pump is connected to an outlet pipe, and the outlet pipe is fixedly connected to the cylinder.

[0011] Specifically, the lower end of the stirring rod penetrates the bottom plate of the cylinder, and the stirring rod and the bottom plate of the cylinder are connected by a water seal for rotational sealing.

[0012] Specifically, the motor is a waterproof motor.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. Inserting the tube ensures that water and fertilizer penetrate from the inside into the root zone soil, rather than flowing to the surface. By delivering drip irrigation water and fertilizer directly to the deep root zone of the soil, water is prevented from being exposed to the air on the surface, thereby effectively reducing evaporation waste and improving water resource utilization.

[0015] 2. Rotating the inner tube can change the overlapping area of ​​the inner and outer holes, enabling continuous flow adjustment. It can adjust the drip irrigation rate in real time and accurately according to different irrigation subjects and soil types, optimizing the water and fertilizer supply effect.

[0016] 3. The end cap and the insert tube are connected by a threaded seal, allowing for quick disassembly of the inner tube for flushing without having to pull the insert tube out of the soil. The removable end cap and inner tube assembly simplifies the cleaning process, prevents clogging that leads to decreased efficiency, and reduces equipment downtime and maintenance costs.

[0017] 4. The corrugated pipe supports free movement and positioning of the drip irrigation head; the retaining ring keeps the inner and outer holes aligned through a limiting action to prevent adjustment failure; the corrugated pipe connection ensures that the position of the drip irrigation head is adjustable; the overall design takes into account both flexibility and stability.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1: Refer to Figures 1-4 As shown, an integrated water and fertilizer drip irrigation device includes a water and fertilizer mixing device.

[0025] The water and fertilizer mixing equipment includes a cylinder 1 with an opening at the top and a cover plate 2 installed at the top of the cylinder 1.

[0026] A support ring 3 is concentrically fixed to the lower end of the cylinder 1. A motor 10, a waterproof motor, is concentrically fixed to the lower end of the cylinder 1 inside the support ring 3. A stirring rod 11 is concentrically rotatably connected inside the cylinder 1. The output shaft of the motor 10 is concentrically fixed to the lower end of the stirring rod 11. Specifically, the lower end of the stirring rod 11 penetrates the bottom plate of the cylinder 1, and the stirring rod 11 and the bottom plate of the cylinder 1 are connected by a water seal for rotational sealing.

[0027] Since motor 10 is a waterproof motor, it can avoid water damage to motor 10 due to water seal failure.

[0028] A submersible pump is fixed inside the cylinder 1 on one side of the stirring rod 11. The outlet end of the submersible pump is connected to the outlet pipe 4, and the outlet pipe 4 is fixedly connected to the cylinder 1.

[0029] One end of the outlet pipe 4 is connected to one end of the hose 5, and the other end of the hose 5 is connected to the main pipe 6. The other end of the main pipe 6 is blocked. Multiple branch pipes 7 are evenly distributed and fixedly connected on both sides of the main pipe 6 along its length. One end of the branch pipe 7 is fixedly connected to one end of the corrugated pipe 8, and the other end of the corrugated pipe 8 is connected to the side pipe 12. The side pipe 12 is fixedly connected to the drip irrigation head 9.

[0030] The drip head 9 includes a tube 901, the lower end of which is sealed and pointed, and multiple external holes 905 are evenly distributed around the side wall of the tube 901.

[0031] The inner tube 903 is rotatably sealed inside the cannula 901. The side tube 12 is fixedly connected to the upper part of the cannula 901 above the inner tube 903, and the side tube 12 is perpendicular to the cannula 901.

[0032] The inner tube 903 is open at the top and sealed at the bottom. The outer edge of the inner tube 903 is rotatably and sealingly connected to the inner edge of the insertion tube 901. Specifically, sealing rings are fixedly fitted at both the upper and lower ends of the outer side of the inner tube 903, and the inner tube 903 is rotatably and sealingly connected to the insertion tube 901 through the sealing rings.

[0033] The inner tube 903 has an inner hole 904 on its side wall, corresponding to the outer hole 905. An end cap 902 is threadedly and sealed to the upper end of the insertion tube 901. An inner rod 906 is concentrically arranged inside the inner tube 903. The lower end of the inner rod 906 is fixedly connected to the lower end of the inner tube 903, and the upper end of the inner rod 906 passes through a through hole in the end cap 902, forming a rotatable and sealed connection with the through hole. Specifically, a sealing ring is fixedly and sealed inside the through hole of the end cap 902, and the inner rod 906 passes through the sealing ring, forming a rotatable and sealed connection with the end cap 902 through the sealing ring.

[0034] In this embodiment, the motor 10 is started, and the motor 10 drives the stirring rod 11 to rotate, adding water and fertilizer into the cylinder 1. The rotating stirring rod 11 can make the fertilizer and water mix thoroughly.

[0035] Insert the cannula 901 into the soil on one side of the plant being irrigated. Since the side tube 12 is connected to the main tube 6 through the corrugated tube 8, the drip head 9 has a high degree of freedom, making it easy to adjust the distance between the drip head 9 and the plant being irrigated.

[0036] Then the submersible pump is started. The submersible pump delivers the water and fertilizer in the cylinder 1 through the outlet pipe 4, hose 5, main pipe 6, branch pipe 7, corrugated pipe 8 and side pipe 12 to the insertion tube 901. The water and fertilizer that enter the insertion tube 901 through the side pipe 12 enter the inner pipe 903 and are discharged through the inner hole 904 and the outer hole 905 and permeate into the soil.

[0037] The inner tube 903 can be rotated via the inner rod 906. During the rotation of the inner tube 903, the connecting part between the inner hole 904 and the outer hole 905 gradually decreases, thus allowing the drip irrigation speed to be adjusted.

[0038] Because the drip irrigation speed is adjustable, this equipment can select the appropriate irrigation speed according to soil conditions and the irrigating entity. When drip irrigating mixed-plant crops, the drip irrigation speed of drip head 9 can be adjusted individually, allowing for the selection of a suitable drip irrigation speed for different irrigating entities.

[0039] When it is necessary to clean the cannula 901 and the inner tube 903, rotate the end cap 902 to separate the end cap 902 from the cannula 901. Then the end cap 902, the inner rod 906 and the inner tube 903 can be pulled out from the cannula 901, which makes it convenient to clean the inside of the inner tube 903 and the inside of the cannula 901 without having to pull the cannula 901 out of the soil.

[0040] Example 2: Based on Example 1, referring to... Figure 3 As shown, a retaining ring 907 is fixed on the inner rod 906 below the end cap 902, and the upper end face of the retaining ring 907 is in contact with the lower end face of the end cap 902.

[0041] By setting a retaining ring 907, after the end cap 902 is threadedly sealed to the upper end of the insertion tube 901, the lower end of the end cap 902 presses against the upper end of the retaining ring 907, thereby limiting the inner tube 903 and ensuring that the inner hole 904 and the outer hole 905 correspond in the circumferential direction of the insertion tube 901, which can ensure accurate adjustment of the drip irrigation speed.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
