Description

Technical Field

[0001] This utility model relates to the field of drip irrigation and fertilization technology, and in particular to a device for the coordinated application of drip irrigation and fertilization. Background Technology

[0002] With the increasing demand for water-saving and fertilizer-saving, and precision irrigation in modern agriculture, drip irrigation technology has been widely used due to its advantages such as high efficiency, water saving, and strong controllability.

[0003] For example, patent number CN223437415U discloses a water and fertilizer integrated construction device that combines deficit irrigation and drip irrigation. It sets up a regulating valve between the water and fertilizer tank and the irrigation mechanism to adjust the irrigation water volume. This allows for proactive reduction of irrigation during specific plant growth stages (such as the vegetative growth period or fruit enlargement period), inducing water stress signals in the plant, promoting root development and nutrient absorption efficiency, and achieving deficit irrigation. The irrigation mechanism of this invention includes two rotating swing arms and an irrigation head, which is a drip irrigation nozzle. During irrigation, the two swing arms combine around the plant's root system to form a circular irrigation ring, and the irrigation head applies fertilizer directly to the plant's root zone, reducing nutrient loss and thus achieving coordinated deficit irrigation and drip irrigation.

[0004] However, during long-term operation, existing drip irrigation fertigation devices suffer from a large number of residual particles in the water and fertilizer. The deposition or scaling of fertilizer particles and impurities leads to nozzle blockage and unstable flow, affecting irrigation uniformity and crop growth. Furthermore, after use, water and fertilizer residue remains on the inner wall of the device, making it difficult to clean. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a drip irrigation fertigation device that solves the problems of existing drip irrigation fertigation devices during long-term operation, such as the large amount of residual particles in the water and fertilizer, fertilizer particles and impurities depositing or scaling, causing nozzle blockage, unstable flow, affecting irrigation uniformity and crop growth, and the difficulty in cleaning water and fertilizer residues remaining on the inner wall of the device after use.

[0006] The technical solution of this utility model is as follows: a drip irrigation fertigation device includes a device shell, a servo motor fixedly connected to the top of the device shell, a rotating shaft fixedly connected to the output end of the servo motor, a guide tube located inside the device shell below the rotating shaft, a filter cylinder fixedly connected to the bottom end of the guide tube, the bottom end of the rotating shaft passing through the device shell and the guide tube and rotatably connected to the filter cylinder, cleaning fan blades A and B respectively provided on both sides of the rotating shaft, one end of cleaning fan blades A and B passing through the guide tube and fitting against the inner wall of the device shell, a filter frame movably connected above cleaning fan blade B located outside the guide tube, contact blocks B and A respectively provided on the opposite surfaces of cleaning fan blades B and A, the top end of contact block B extending to the bottom end of contact block A, a connecting pipe penetrating the bottom end of the filter cylinder located below the device shell, a monitoring device fixedly connected to one side of the outer surface of the connecting pipe, and a nozzle seat fixedly connected to the bottom end of the connecting pipe.

[0007] Preferably, the device housing has inlets on both sides of the top surface, which are connected to the housing. Six spray heads are evenly distributed on both sides of the bottom of the nozzle holder. The device can input and spray water and fertilizer through the inlets and spray heads. A control panel is fixedly connected to the front of the housing. The control panel is electrically connected to the servo motor and the monitoring device. The servo motor and the monitoring device can be controlled through the control panel.

[0008] Preferably, the monitoring device includes a water pump, with a solenoid valve fixedly connected to the top of the water pump. One end of the solenoid valve is equipped with a flow sensor on the inner wall of the monitoring device. When the solenoid valve is opened, the water pump, in conjunction with the spray head, sprays water and fertilizer from inside the device housing. During the spraying process, the flow sensor monitors the output of water and fertilizer. If the water and fertilizer flow rate is low, the flow sensor transmits a signal to the control panel.

[0009] Preferably, the device housing and the guide tube are an integral structure. The top end of the guide tube has a through hole. One end of the rotating shaft passes through the through hole and is rotatably connected to the top end of the filter cylinder. The rotating shaft, the cleaning fan blade A, and the connecting spring are all integral structures. One end of the cleaning fan blade A and the cleaning fan blade B has a rotating hole on the inner wall of the guide tube. One end of the cleaning fan blade A and the cleaning fan blade B passes through the rotating hole and fits against the inner wall of the device housing.

[0010] Preferably, cleaning blades are provided on the top surface of cleaning blade A and the bottom surface of cleaning blade B. The top surface of cleaning blade A is attached to the top of the inner wall of the device housing, and the bottom of cleaning blade B is attached to the bottom of the inner wall of the device housing. When the rotating shaft drives cleaning blade A and cleaning blade B to rotate, cleaning blade A and cleaning blade B work together with the cleaning blades to clean the device.

[0011] Preferably, the cleaning fan blade B and the contact block B are an integral structure, and the filter frame and the contact block A are an integral structure. The top end of the contact block B and the bottom end of the contact block A are both inclined surfaces. The contact block B fits into the contact block A through the inclined surfaces. When the cleaning fan blade B rotates, the cleaning fan blade B, in conjunction with the contact block B, contacts the contact block A at the bottom end of the filter frame, causing the filter frame to move on the outer surface of the guide tube.

[0012] Preferably, a guide groove is formed on the outer surface of the guide tube, one end of the filter frame extends to the inner side of the guide groove, and a connecting spring is fixedly connected to the bottom of the filter frame located on the inner wall of the guide groove. The filter frame is movably connected to the guide tube through the connecting spring. The guide groove has a wave-shaped structure, which causes the filter frame to vibrate during the up and down displacement process, thereby improving the impurity removal efficiency.

[0013] The beneficial effects of this utility model are: This drip irrigation and fertigation device uses a dual filtration process where water and fertilizer pass through a filter frame and a filter cylinder in sequence. This effectively removes impurities, significantly improves water and fertilizer cleanliness, and reduces the risk of nozzle clogging. The device monitors the output flow rate, and if an abnormal flow rate is detected, a servo motor drives cleaning blades A and B to rotate, simultaneously scraping away deposits on the inner wall of the device. Cleaning blade B, through an inclined contact block, pushes the filter frame to vibrate up and down along a wave-shaped guide groove, efficiently shaking off impurities from the filter screen surface, preventing filter screen clogging, and extending the equipment's service life.

One end of the cleaning fan blade B16 passes through the guide tube 8 and fits against the inner wall of the device housing 1. Above the cleaning fan blade B16, on the outside of the guide tube 8, a filter frame 11 is movably connected. On the opposite sides of the cleaning fan blade B16 and the cleaning fan blade A10, contact blocks B14 and A13 are respectively provided. The top of the contact block B14 extends to the bottom of the contact block A13. Below the filter cylinder 12, at the bottom of the device housing 1, a connecting pipe 7 is connected through. A monitoring device 15 is fixedly connected to one side of the outer surface of the connecting pipe 7. The bottom of the connecting pipe 7 is fixedly connected to the nozzle seat 3.

[0018] Please see Figures 1-2 In this embodiment, the device housing 1 has inlets 6 on both sides of the top surface, and the inlets 6 are connected to the device housing 1. Six spray heads 4 are evenly distributed on both sides of the bottom of the nozzle seat 3. The device can input and spray water and fertilizer through the inlets 6 and the spray heads 4. The front end of the device housing 1 is fixedly connected to the control panel 2. The control panel 2 is electrically connected to the servo motor 5 and the monitoring device 15. The control panel 2 can control the servo motor 5 and the monitoring device 15 respectively. The monitoring device 15 includes a water pump. The top of the water pump is fixedly connected to a solenoid valve. One end of the solenoid valve is located on the inner wall of the monitoring device 15 and a flow sensor is set thereon. When the solenoid valve is opened, the water pump works with the spray heads 4 to spray the water and fertilizer inside the device housing 1. During the water and fertilizer spraying process, the flow sensor monitors the output of water and fertilizer. If the water and fertilizer flow is low, the flow sensor transmits a signal to the control panel 2. The six spray heads 4 adopt a self-cleaning rotating nozzle structure and have a micro turbine inside. When water flows through, the nozzles automatically rotate to flush the nozzle holes. The nozzle material is anti-clogging and wear-resistant ceramic material.

[0019] Please see Figures 3-4In this embodiment, the device housing 1 and the guide tube 8 are an integral structure. A through hole is provided at the top end of the guide tube 8. One end of the rotating shaft 17 passes through the through hole and is rotatably connected to the top end of the filter cylinder 12. The rotating shaft 17, the cleaning fan blade A10, and the connecting spring 18 are all integral structures. One end of the cleaning fan blade A10 and the cleaning fan blade B16 is provided with a rotating hole on the inner wall of the guide tube 8. One end of the cleaning fan blade A10 and the cleaning fan blade B16 passes through the rotating hole and fits against the inner wall of the device housing 1. Cleaning scrapers are provided on the top surface of the cleaning fan blade A10 and the bottom surface of the cleaning fan blade B16. The top surface of the cleaning fan blade A10 fits against the top end of the inner wall of the device housing 1, and the bottom end of the cleaning fan blade B16 fits against the bottom end of the inner wall of the device housing 1. When the rotating shaft 17 drives the cleaning fan blade A10 and the cleaning fan blade B16 to rotate, the cleaning fan blade A10 and the cleaning fan blade B16 work together with the cleaning scrapers to clean the device. The cleaning blade is made of polytetrafluoroethylene or silicone. The cleaning fan blade B16 and the contact block B14 are integrated. The filter frame 11 and the contact block A13 are integrated. The top of the contact block B14 and the bottom of the contact block A13 are both inclined. The contact block B14 fits into the contact block A13 through the inclined surface. When the cleaning fan blade B16 rotates, the cleaning fan blade B16, in conjunction with the contact block B14, contacts the contact block A13 at the bottom of the filter frame 11, causing the filter frame 11 to move on the outer surface of the guide tube 8. A guide groove 9 is provided on the outer surface of the guide tube 8. One end of the filter frame 11 extends to the inner side of the guide groove 9. A connecting spring 18 is fixedly connected to the bottom of the filter frame 11 located on the inner wall of the guide groove 9. The filter frame 11 is movably connected to the guide tube 8 through the connecting spring 18. The guide groove 9 has a wave-shaped structure, which causes the filter frame 11 to vibrate during the up and down movement, improving the impurity removal efficiency.

[0020] When working, place the device in a suitable position, connect the power supply, start the device, and pour water and fertilizer into the inside of the device through the feed port 6 at the top of the device housing 1. The water and fertilizer are filtered through the filter frame 11 and the filter cylinder 12 in sequence to improve the quality of the water and fertilizer. The filtered water and fertilizer are sprayed through the connecting pipe 7 with the nozzle seat 3 and the spray head 4. During the water and fertilizer spraying process, the flow sensor inside the monitoring device 15 monitors the output of water and fertilizer. If the water and fertilizer flow is low, the flow sensor transmits the signal to the control panel 2. The control panel 2 starts the servo motor 5. The servo motor 5, together with the cleaning fan blades A10 and B16, cleans the inner wall of the device. During the rotation of the cleaning fan blade B16, the cleaning fan blade B16, together with the contact block B14, contacts the contact block A13 at the bottom of the filter frame 11, so that the filter frame 11 moves on the outer surface of the guide tube 8. The guide groove 9 has a wave-shaped structure, so that the filter frame 11 vibrates during the up and down movement, improving the efficiency of impurity removal. Compared to the prior art document CN223437415U, a water and fertilizer integrated construction device that combines deficit irrigation and drip irrigation is provided, a regulating valve is set between the water and fertilizer tank and the irrigation mechanism. The regulating valve is used to adjust the irrigation water volume so as to actively reduce the irrigation volume at specific growth stages of the plant (such as the vegetative growth period or the fruit enlargement period), induce the plant to generate water stress signals, promote root development and nutrient absorption efficiency, and achieve deficit irrigation. The irrigation mechanism of this utility model includes two rotating swing arms and an irrigation head, which is a drip irrigation nozzle. During irrigation, the two swing arms combine around the plant's root system to form a circular irrigation ring, and the irrigation head is used to fertilize the plant's roots, allowing fertilizer to be directly delivered to the root zone, reducing nutrient loss. This achieves the coordinated operation of deficit irrigation and drip irrigation. This application uses a double filtration system where water and fertilizer pass through a filter frame and a filter cylinder in sequence, effectively removing impurities, significantly improving water and fertilizer cleanliness, and reducing the risk of nozzle clogging. The output flow is monitored by a monitoring device. Once an abnormal flow is detected, the cleaning fan blades A and B are driven to rotate by a servo motor, simultaneously scraping off the deposits on the inner wall of the device. The cleaning fan blade B pushes the filter frame to vibrate up and down along the wave-shaped guide groove through the inclined contact block, efficiently shaking off impurities on the filter screen surface, preventing filter screen clogging, and extending the service life of the equipment.
