Description

Technical Field

[0001] This invention relates to the field of agricultural automated irrigation technology, and more specifically, to an improved nozzle for an agricultural irrigation robot. Background Technology

[0002] The development of modern agriculture has placed higher demands on the precision, intelligence, and efficiency of irrigation operations. Traditional irrigation methods, such as manual flood irrigation or automatic sprinkler systems based on fixed time sequences, have inherent drawbacks such as low water resource utilization, poor irrigation uniformity, and high labor costs.

[0003] Specifically, mainstream irrigation equipment in current technology typically uses nozzles of fixed size. This design results in a constant water coverage area and flow rate, making it unsuitable for complex and varied field conditions. For example, when irrigating fields with irregular shapes or varying sizes, fixed-nozzle equipment struggles to achieve proper water distribution, often leading to excessive water in the near-end crop area, causing waterlogging or fertilizer loss, while the far-end crop area suffers from insufficient water, hindering normal growth and ultimately limiting crop yield and quality.

[0004] Furthermore, in irrigation processes requiring the application of liquid fertilizers or pesticides (collectively referred to as "pesticides"), existing equipment largely relies on a fixed concentration model where the pesticides are pre-mixed and diluted in storage tanks. This method lacks flexibility and cannot allow for real-time, precise online adjustment of pesticide concentrations according to the specific needs of crops at different growth stages. This not only risks causing pesticide or fertilizer damage due to improper concentrations but also limits the full realization of the advantages of integrated water and fertilizer technology.

[0005] Meanwhile, existing irrigation sprinklers generally have poor compatibility with water pipes of different specifications, mobile robot platforms, or other irrigation tools. Their interfaces and connection methods are often limited, resulting in cumbersome procedures for users during installation, replacement, and maintenance. This increases the deployment cost and application limitations of the equipment, making it difficult to meet the requirements of modern precision agriculture for equipment versatility and convenience. Summary of the Invention

[0006] In view of the deficiencies in the existing technology, the present invention proposes an improved nozzle for an agricultural irrigation robot to overcome the aforementioned technical problems in the existing related technologies.

[0007] Therefore, the specific technical solution adopted by the present invention is as follows: An improved nozzle for an agricultural irrigation robot includes a smart operating platform such as a mobile phone. A clamping device is connected to the back of the platform to hold it. The clamping device is connected to the platform via a connecting shaft. A spring bracket connects the clamping device and a handle. A water spray guide is connected to the handle. A switch and a power button are located on the handle for controlling water output. Clamping plates are fixedly connected to both sides of the top of the water outlet, and a connecting interface is fixedly connected to the bottom of the outlet. A thread is provided on the outer circumference of the bottom of the connecting interface, allowing the outlet to be movably connected to the end of the water spray guide via the thread. A detachable mounting base is located at the bottom of the spring bracket for detachably installing the water spray guide.

[0008] Preferably, the clamping device includes clamping claws with a trapezoidal silicone pad mounted on them to protect the electronic device from impacts. The overall model of the clamping device is made of nylon material to ensure structural strength and provides waterproof and fireproof functions. The design of the clamping claws in conjunction with the trapezoidal silicone pad increases the contact area and friction with the device, which can not only firmly clamp mobile devices of different sizes, but also effectively prevent the device surface from being scratched or damaged by excessive clamping force. Using nylon material to make the overall model not only ensures that the clamping device has sufficient mechanical strength to withstand external forces during use, but its inherent waterproof and fireproof properties also significantly improve the adaptability and safety of the device in humid and dusty agricultural environments, extending its service life.

[0009] Preferably, the spring bracket is made of nylon and aluminum alloy, with the bracket's rotating bearing using aluminum alloy. The nylon portion of the spring bracket is a long strip with grooves on both sides. These grooves are used to fix the rotating shaft and are designed with slots for secure fixing. Hollow semi-circular protrusions on both sides are designed to install the spring, achieving a rebound function. By using a combination of nylon and aluminum alloy, an optimal balance between lightweight and high strength is achieved in the spring bracket. The groove and slot design of the nylon portion ensures the accuracy and stability of the rotating shaft installation, preventing loosening after long-term use. The hollow semi-circular protrusions on both sides provide a stable and protected installation space for the spring, enabling the spring bracket to provide reliable rebound force, ensuring the equipment can maintain its position stably after angle adjustment. It also facilitates multi-angle, stepless adjustment by the user, improving operational convenience and user experience.

[0010] Preferably, the handle is made using 3D printing, is hollow inside, lightweight, and easy to grip. The rear of the handle is arc-shaped to increase grip comfort and prevent bumps to the equipment. The handle has two circular buttons, serving as a power switch and a control button for adjusting water flow and shutting off the device. By employing 3D printing technology combined with a hollow design, the handle achieves maximum weight reduction while maintaining structural strength, effectively reducing operator fatigue. The arc-shaped rear is more ergonomic, fitting comfortably in the palm and reducing discomfort during prolonged use. The smooth shape also prevents sharp edges from causing accidental bumps to the user or equipment. The separate circular power switch and control buttons are clearly laid out and have distinct tactile feedback, allowing operators to accurately turn the device on / off and adjust water flow without direct visual inspection, improving work efficiency and safety.

[0011] Preferably, the water spray guide is made of PVC hose, which is corrosion-resistant and suitable for transporting chemicals. The connection between the water spray guide and the handle is a steel connector. By using PVC hose as the water spray guide, its inherent flexibility makes the equipment more flexible and convenient to move and operate in the field. Its excellent corrosion resistance allows it to withstand the erosion of chemicals such as pesticides and fertilizers, broadening its application range and reducing the frequency of maintenance and replacement. Using a steel connector at key connections provides mechanical strength and durability far exceeding that of plastic materials, ensuring a firm and reliable connection between the water spray guide and the handle, effectively preventing loosening, cracking, or leakage caused by frequent operation or accidental pulling.

[0012] Preferably, the disassembly / assembly base has a sliding groove inside, and a trajectory groove is formed at the upper end of the sliding groove. Two spring beads are installed at the ends of the trajectory groove, and they are arranged opposite each other to form a clamping mechanism. The trajectory groove is arranged along the length of the disassembly / assembly base, and its diameter gradually decreases along the length direction. This design creates a clever quick-assembly / disassembly mechanism. The cooperation between the sliding groove and the trajectory groove provides clear guidance for installation. The gradual diameter design of the trajectory groove allows the installed parts to be gradually locked during sliding, ultimately achieving precise positioning and stable clamping by the spring beads at their opposite ends. This structure eliminates the traditional screw fixing method, making the replacement of water spray pipes or other accessories exceptionally quick, greatly improving work efficiency, and also avoiding installation difficulties caused by stripped threads or lost tools.

[0013] Preferably, the bottom of the disassembly / assembly base is movably connected to an installation base, the top of the installation base is fixedly connected to a connecting base, and both sides of the connecting base are fixedly connected to sliders, which are slidably connected inside the slide groove. Balls are also installed on both sides of the connecting base, embedded in the track groove. When the connecting base drives the installation base to slide along the slide groove to a certain position, the ball abuts against a spring ball, causing the spring ball to clamp the ball, thus achieving installation and disassembly. The cooperation between the installation base and the disassembly / assembly base achieves modular connection. The movement of the slider within the slide groove ensures the straightness and stability of the connection, preventing radial wobbling. The interaction between the ball and the spring ball is the core of the locking mechanism. When sliding to the predetermined position, the spring ball generates a clamping force on the ball, producing a clear "click" sound or tactile feedback, clearly indicating to the user that the installation is in place. This ensures the reliability of the connection and makes the disassembly process simple and direct (simply apply sufficient pulling force to separate). This design greatly facilitates the rapid replacement of different functional modules (such as different lengths of water spray pipes or different types of nozzles) under different operational needs.

[0014] Preferably, the water spray guide pipe, through the cooperation of the disassembly and mounting bases, facilitates the replacement of water spray guide pipes of different diameters, making it suitable for irrigation of different areas in agriculture. This design endows the entire irrigation system with a high degree of flexibility and versatility. Users can quickly replace water spray guide pipes with different flow rates and ranges according to specific irrigation needs, such as large-area spraying or small-scale precision drip irrigation. This modular design concept allows a single main unit to adapt to various operating scenarios, reducing investment in multiple sets of dedicated equipment, simplifying equipment management and maintenance, and significantly improving the overall economic benefits and application range of the equipment.

[0015] Preferably, the intelligent operating platform, such as the mobile phone, is connected to the control circuit signal of the nozzle. The intelligent operating platform sends instructions to adjust the water output by linking the switch button and control the start and stop of the nozzle by linking the power button. The corrosion-resistant properties of the water spray pipe are suitable for the delivery of water, fertilizer, and pesticides. The monitoring function of the intelligent operating platform works in conjunction with the water output control of the nozzle to provide hardware support for the online adjustment of water and fertilizer concentration.

[0016] Preferably, the clip at the top of the outlet is used to fix the auxiliary spraying accessory, and the thread of the interface realizes the sealed connection between the outlet and the spray pipe; the sliding groove of the disassembly base and the slider of the mounting base are guided and matched, and the trajectory groove, spring ball and ball clamp and fix, so that the spray pipe can be quickly disassembled and assembled to adapt to irrigation needs with different flow rates and ranges.

[0017] The beneficial effects of this invention are as follows: 1. The spray nozzles integrate a device for holding smartphones and other smart operating platforms, facilitating real-time monitoring and precise control of the irrigation process via smart terminals. Combined with a corrosion-resistant conduit design, this provides the hardware foundation for on-demand, online, precise adjustment of water, fertilizer, or pesticide concentrations, overcoming the lack of flexibility inherent in traditional fixed-concentration mixing methods.

[0018] 2. The quick-release design allows for adaptation to different sizes of water pipes, and the adjustable clamping and connection structure enables the nozzles to adapt to the irrigation needs of fields of different shapes and sizes, achieving a reasonable distribution of water volume. This effectively solves the problem of excessive water volume at the near end and insufficient water volume at the far end caused by fixed nozzles, thus improving irrigation uniformity and water resource utilization.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] According to an embodiment of the present invention, an improved nozzle for an agricultural irrigation robot is provided.

[0024] Example 1; like Figure 1-5 As shown, the improved nozzle of the agricultural irrigation robot according to an embodiment of the present invention includes a smart operating platform 1 such as a mobile phone. A clamping device 2 is connected to the back of the smart operating platform 1. The clamping device 2 is used to clamp the smart operating platform 1. The clamping device 2 is connected to the smart operating platform 1 via a connecting shaft 3. A spring bracket 4 connects the clamping device 2 and a handle 5. A water spraying pipe 6 is connected to the handle 5. A switch button 7 and a power button 8 are provided on the handle 5 for controlling water output. Clips 10 are fixedly connected to both sides of the top of the water outlet 9. A mating interface 11 is fixedly connected to the bottom of the water outlet 9. A thread 12 is provided on the outer circumference of the bottom of the mating interface 11. The water outlet 9 is movably connected to the end of the water spraying pipe 6 via the thread 12. A disassembly and assembly seat 13 is provided at the bottom of the spring bracket 4 for detachably installing the water spraying pipe 6.

[0025] In this embodiment, the clamping device 2 includes clamping claws with trapezoidal silicone pads installed on them to protect the electronic equipment from impacts. The overall model of the clamping device 2 is made of nylon material to ensure structural strength and provides waterproof and fireproof functions. The design of the clamping claws in conjunction with the trapezoidal silicone pads increases the contact area and friction with the equipment, which can not only firmly clamp mobile devices of different sizes, but also effectively prevent the surface of the equipment from being scratched or damaged by excessive clamping force. The use of nylon material to make the overall model not only ensures that the clamping device 2 has sufficient mechanical strength to withstand external forces during use, but its inherent waterproof and fireproof properties also significantly improve the adaptability and safety of the equipment in humid and dusty agricultural environments, extending its service life.

[0026] In this embodiment, the spring bracket 4 is made of nylon and aluminum alloy, with the bracket's rotating bearing using aluminum alloy. The nylon portion of the spring bracket 4 is a long strip with grooves on both sides. The grooves are used to fix the rotating shaft and are designed with slots for fixation. Hollow semi-circular protrusions on both sides are designed to install the spring, achieving a rebound function. By using a combination of nylon and aluminum alloy materials, the optimal balance between lightweight and high strength is achieved in the spring bracket 4. The groove and slot design of the nylon portion ensures the accuracy and stability of the rotating shaft installation, preventing loosening after long-term use. The hollow semi-circular protrusion structure on both sides provides a stable and protected installation space for the spring, enabling the spring bracket 4 to provide reliable rebound force, ensuring that the equipment can maintain its position stably after angle adjustment. It also facilitates multi-angle, stepless adjustment by the user, improving the convenience and experience of operation.

[0027] In this embodiment, the handle 5 is 3D printed, hollow inside, lightweight, and easy to hold. The rear of the handle 5 is rounded to increase grip comfort and prevent bumps to the equipment. The handle 5 has two circular buttons, serving as the power switch 7 and power on button 8, used to control water flow and turn the device off. By employing 3D printing technology combined with a hollow design, the handle 5 achieves maximum weight reduction while maintaining structural strength, effectively reducing operator fatigue. The rounded rear shape is more ergonomic, fitting well in the palm and reducing discomfort during prolonged use. The smooth shape also prevents sharp edges from causing accidental bumps to the user or equipment. The separate circular power switch and power on buttons are clearly laid out and have distinct tactile feedback, allowing the operator to accurately turn the device on / off and adjust the water flow without direct visual inspection, improving work efficiency and safety.

[0028] In this embodiment, the water spraying conduit 6 is made of PVC hose, which is corrosion-resistant and suitable for transporting chemicals. The connection between the water spraying conduit 6 and the handle 5 is a steel connector 11. By using PVC hose as the water spraying conduit 6, its inherent flexibility makes the equipment more flexible and convenient to move and operate in the field. Its excellent corrosion resistance allows it to withstand the erosion of chemicals such as pesticides and fertilizers, broadening its application range and reducing the frequency of maintenance and replacement. The use of a steel connector 11 at the critical connection provides mechanical strength and durability far exceeding that of plastic materials, ensuring a firm and reliable connection between the water spraying conduit 6 and the handle 5, and effectively preventing problems such as loosening, cracking, or leakage of the interface due to frequent operation or accidental pulling.

[0029] In this embodiment, a sliding groove 1301 is formed inside the mounting base 13, and a trajectory groove 1302 is formed at the upper end of the sliding groove 1301. Two spring beads 1303 are installed at the ends of the trajectory groove 1302, and they are arranged opposite each other to form a clamping mechanism. The trajectory groove 1302 is arranged along the length direction of the mounting base 13, and its diameter gradually decreases along the length direction. This design creates a clever quick-installation and quick-disassembly mechanism. The cooperation between the sliding groove 1301 and the trajectory groove 1302 provides clear guidance for installation. The gradual diameter design of the trajectory groove allows the installed components to be gradually locked during sliding, and finally, precise positioning and stable clamping are achieved by the spring beads 1303 arranged opposite each other at their ends. This structure eliminates the traditional screw fixing method, making the replacement of the water spray pipe 6 or other accessories exceptionally quick, greatly improving work efficiency, and also avoiding installation difficulties caused by stripped threads or lost tools.

[0030] In this embodiment, a mounting base 14 is movably connected to the bottom of the mounting base 13, and a connecting base 1401 is fixedly connected to the top of the mounting base 14. Slider blocks 1402 are fixedly connected to both sides of the connecting base 1401, and the sliders 1402 are slidably connected inside the groove 1301. Balls 1403 are also installed on both sides of the connecting base 1401, embedded in the track groove 1302. When the connecting base 1401 drives the mounting base 14 to slide along the groove 1301 to a certain position, the balls 1403 abut against the spring beads 1303, causing the spring beads 1303 to clamp the balls 1403, thereby achieving installation and disassembly. The modular connection is achieved through the cooperation between the mounting base 14 and the mounting base 13. The movement of the sliders 1402 within the groove 1301 ensures the straightness and stability of the connection and prevents radial wobbling. The interaction between ball 1403 and spring ball 1303 is the core of the locking mechanism. When slid to the predetermined position, spring ball 1303 generates a clamping force on ball 1403, producing a clear "click" sound or tactile feedback, clearly indicating to the user that the installation is in place. This ensures the reliability of the connection and makes disassembly simple and direct (simply apply sufficient pulling force to separate). This design greatly facilitates the quick replacement of different functional modules (such as different lengths of water spray pipes or different types of nozzles) under different operational needs.

[0031] In this embodiment, the water spray pipe 6, through the cooperation of the disassembly base 13 and the mounting base 14, facilitates the replacement of water spray pipes 6 with different diameters, making it suitable for irrigation of different areas in agriculture. This design endows the entire irrigation system with a high degree of flexibility and versatility. Users can quickly replace water spray pipes with different flow rates and ranges according to specific irrigation needs, such as large-area spraying or small-scale precision drip irrigation. This modular design concept enables a single main unit to adapt to various operating scenarios, reducing investment in multiple sets of dedicated equipment, simplifying equipment management and maintenance, and significantly improving the overall economic benefits and application scope of the equipment.

[0032] In this invention, a smart operating platform 1, such as a mobile phone, is connected to the control circuit signal of the nozzle. The smart operating platform 1 sends instructions to the switch button 7 to adjust the water output and to the power button 8 to control the start and stop of the nozzle. The corrosion-resistant properties of the water spray pipe 6 are suitable for the delivery of water, fertilizer, and pesticides. The monitoring function of the smart operating platform 1 works in conjunction with the water output control of the nozzle to provide hardware support for the online adjustment of water and fertilizer concentration.

[0033] In this invention, the clip 10 at the top of the outlet 9 is used to fix the auxiliary spraying accessory, and the thread 12 of the interface 11 achieves a sealed connection between the outlet 9 and the spray pipe 6; the sliding groove 1301 of the disassembly and assembly base 13 and the slider 1402 of the mounting base 14 are guided and engaged, and the trajectory groove 1302, spring ball 1303 and ball 1403 are clamped and fixed, so that the spray pipe 6 can be quickly disassembled and assembled to adapt to irrigation needs with different flow rates and ranges.

[0034] To facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process will be described in detail below.

[0035] In practical applications, the smartphone or other smart operating platform 1 is first secured using the clamping device 2 on the back. The clamping claws, under the action of springs or a mechanical structure, grip both sides of the device. The trapezoidal silicone pads on the claws increase friction and prevent scratches on the device surface. The clamping device 2 is connected to the spring bracket 4 via a connecting shaft 3, allowing the clamping part to rotate at a certain angle relative to the handle 5. Users can manually adjust the angle of the clamping device 2 holding the smartphone or other smart operating platform 1 according to their observation needs. The spring mechanism designed inside the spring bracket 4 provides rebound force and friction. When the user applies external force to change the angle, the spring is compressed or stretched. When the external force is removed after adjusting to the appropriate angle, the spring's rebound force balances the friction generated by the internal mechanical structure, such as grooves, slots, and the rotating shaft, thereby locking the spring bracket 4 at the current angle. This achieves multi-angle, stepless stable support, facilitating the user's observation of the screen or use of the camera. Pressing the "Power Button" 8 on the grip 5 may be used to start the device's electronic system or enter standby mode. Pressing the "Switch Button" 7 triggers an electronic control signal, driving the internal solenoid valve or micro water pump, usually located in the robot body or upstream pipeline, to open via a pipeline connected to the nozzle, allowing water or a liquid mixed with fertilizer / pesticide to pass through. The liquid flows through the internal channel of the grip 5 into the connected water spray conduit 6. The water spray conduit 6 is made of corrosion-resistant PVC hose, suitable for conveying various agricultural agents, and the liquid finally reaches the outlet 9. The outlet 9 is movably connected to the end of the water spray conduit 6 via a thread 12, facilitating individual replacement or cleaning. The clip 10 at the top of the outlet may be used to assist in fixing or installing other accessories such as different types of nozzles. Liquid is sprayed out from the outlet 9 to complete irrigation or pesticide application. Users can remotely send commands through a specific application running on a smart operating platform 1, such as a mobile phone, to indirectly control the circuit behind the switch button 7 and the power button 8, achieving a higher level of precise control over the water outlet switch, water flow rate, and even the pesticide mixing ratio. Finally, when it is necessary to adapt to different irrigation areas or replace different specifications of the spray pipe 6, a quick-installation and quick-disassembly mechanism composed of the disassembly base 13 and the mounting base 14 is used to apply a certain axial tension to the installed spray pipe 6 and its connected mounting base 14. The pulling force overcomes the clamping force of the two opposing spring beads 1303 at the end of the track groove 1302 on the ball 1403 on the connector 1401, causing the ball 1403 to exit along the track groove 1302. The slider 1402 slides out of the slide groove 1301, thereby removing the entire water spray pipe module. The sliders 1402 on both sides of the connector 1401 at the top of the water spray pipe module to be installed are aligned with the inlet of the slide groove 1301 inside the mounting base 13, and then the mounting base 14 is pushed along the slide groove 1301. During this process, the balls 1403 on both sides of the connector 1401 enter and slide along the track groove 1302.As the diameter of the track groove 1302 gradually decreases along the sliding direction, the spatial constraint on the ball 1403 gradually increases, eventually being tightly clamped and fixed by the spring ball 1303 at the end, usually accompanied by a "click" sound or tactile feedback indicating placement. At this point, the water spray guide 6 is securely and sealed to the main body. This invention, through innovative mechanical structure design, achieves intelligent integration of the handheld irrigation terminal, flexible viewing angle adjustment, comfortable and convenient operation, and rapid replacement of the core actuator, the water spray guide 6. Its core working principle combines user grip operation, manual / intelligent control, and modular fluid pathways, ultimately achieving precise, efficient, and highly adaptable agricultural irrigation operations through a series of precise mechanical connections and locking mechanisms.

[0036] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
