[0027] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0028] like Figure 1 As shown, a forestry pest and disease control sprayer of this application includes multiple components, namely a pesticide storage tank 1, a pesticide delivery pipe 2, an atomizing nozzle 3, a connecting frame 4, and a pressure pump 5. These components, through a rational structural design and assembly relationship, achieve uniform distribution of pesticide solution in the forestry environment, thereby improving the pest and disease control effect.

[0029] The pesticide storage tank 1 is used to store pesticide solutions and is typically made of corrosion-resistant materials to ensure that the solution will not deteriorate due to chemical reactions with the materials. The storage tank 1 has an outlet at its bottom, which connects directly to the delivery pipe 2. This connection method ensures that the pesticide solution flows out of the storage tank 1 without leakage or blockage, and the design capacity of the storage tank 1 can be adjusted to suit different spraying needs. For example, the storage tank 1 can be manufactured by injection molding, with internal reinforcing ribs to improve strength and stability.

[0030] The function of the delivery tube 2 is to transfer the liquid medicine from the storage tank 1 to the atomizing nozzle 3. The delivery tube 2 is typically made of a flexible, pressure-resistant, and corrosion-resistant polymer material. One end is fixedly connected to the outlet of the storage tank 1, and the other end is connected to the atomizing nozzle 3 via a thread or other reliable mechanical interface. The flexible design of the delivery tube 2 allows it to adapt to different spraying scenarios while reducing the risk of connection failure due to external interference. Technically, this function can be achieved by verifying its load-bearing capacity and sealing performance through high-pressure pipeline testing.

[0031] The function of the atomizing nozzle 3 is to spray the liquid medicine into a mist so as to cover the target area more widely. The atomizing nozzle 3 contains multiple layers of staggered guide vanes 31 (see details). Figure 3 This design significantly enhances the turbulence effect during drug flow, resulting in finer and more uniformly dispersed drug particles. An annular groove 32 is also provided externally (see details). Figure 4 This groove can form multiple atomization zones, allowing the liquid medicine to be fully broken into tiny droplets before entering the micro-nozzles 33. The micro-nozzles 33 at the top are evenly arranged, which helps to further improve the uniformity of liquid medicine distribution. For example, the guide plate 31 can be formed by precision cutting process, and the annular groove 32 and micro-nozzles 33 can be manufactured by precision stamping and CNC machine tools to ensure stable and reliable atomization quality.

[0032] The connecting frame 4 is used to fix the atomizing nozzle 3 and has a key feature: it connects to the atomizing nozzle 3 through an adjustable-angle joint structure. This allows the atomizing nozzle 3 to flexibly adjust its spray direction according to actual operational needs. Specifically, the joint structure on the connecting frame 4 includes a ball joint and its matching locking device. The operator can simply loosen the locking device to adjust the nozzle angle arbitrarily and then relock it. Technically, this joint mechanism was designed by rapidly prototyping 3D printed parts and undergoing multiple optimization experiments to ensure simple operation and stable reliability.

[0033] The pressure pump 5, located in the middle of the delivery pipe 2, provides the necessary pressure for the pesticide flow in the entire spraying system. Connecting the storage tank 1 to the atomizing nozzle 3, the pressure pump 5 pressurizes the pesticide, ensuring its smooth delivery from the storage tank 1 to the atomizing nozzle 3, thus achieving the desired spray effect. To meet the needs of large-area spraying, the pressure pump 5 can be a high-pressure pump such as a reciprocating plunger pump or a diaphragm pump. By controlling the flow rate and output pressure level of the pressure pump 5, ideal spraying distance and density can be achieved in practical applications. This pressure pump 5 can be integrated into the overall equipment via an electrical control system, such as an AC motor-driven plunger pump, allowing for adjustments to its operating status based on real-time conditions.

[0034] To address the technical challenge of achieving more uniform pesticide distribution, this application proposes a systematic solution: Firstly, the atomizing nozzle 3 incorporates multiple layers of staggered guide vanes 31 to enhance the turbulence of the pesticide flow. Secondly, the outer annular groove 32, combined with micro-nozzles 33, disperses a single water flow into multi-layered, highly uniform atomized aerosol particles, significantly improving the coverage and particle distribution accuracy during spraying. Simultaneously, the adjustable-angle connecting frame 4 allows the nozzle to flexibly adjust its orientation, ensuring effective spraying even in complex terrain conditions. Combined with the pesticide supply from the storage tank 1 and the stable driving force generated by the pressure pump 5, this application achieves large-area, highly uniform spraying in forest environments, significantly improving the actual effectiveness of pest and disease control.

[0035] like Figure 3 As shown, in one embodiment, the atomizing nozzle 3 of a forestry pest and disease sprayer of this application includes a multi-layered, staggered guide vanes 31 structure. These guide vanes 31 are composed of several serrated guide plates 311 of different heights and are installed in the internal space of the atomizing nozzle 3. Specifically, the guide vanes 31 are staggered in the longitudinal and transverse directions, and the height of the serrated guide plates 311 varies according to their arrangement. This design can effectively increase the turbulence effect during the flow of the pesticide liquid, thereby further refining and atomizing the pesticide liquid. These serrated guide plates 311 are arranged in a regular manner on the inner wall of the pesticide delivery channel, working in conjunction with the outer annular groove 32 and the top micro-spray holes 33.

[0036] To achieve this feature, the technical arrangement can be as follows: For example, during the manufacturing process, the serrated guide plate 311 is embedded into a predetermined position inside the atomizing nozzle 3 through precision machining, and the guide plates are precisely staggered using mold forming. Subsequently, after assembly, the turbulence performance of its internal flow channel can be tested through actual spraying experiments to verify whether it meets the expected standard, thereby verifying the consistency and stability of the design.

[0037] like Figure 4 As shown, in one embodiment, the annular groove 32 of a forestry pest and disease sprayer of this application is provided with multiple baffles 321 for refining the airflow and promoting the formation of multiple atomization zones. Specifically, the baffles 321 are installed inside the annular groove 32 and are evenly distributed along the radial direction. This design can effectively cut the airflow and achieve the generation of finer atomized particles by increasing the degree of turbulence. These baffles 321 have a plate-like or sheet-like structure and are arranged at fixed intervals, generating a significant diversion effect when the airflow passes through them. In addition, these components do not require additional fixing devices and can be directly embedded inside the annular groove 32 to meet the usage requirements.

[0038] For example, suitable materials can be selected to manufacture the baffles 321, such as high-strength and corrosion-resistant stainless steel or plastic composite materials, ensuring their thickness is moderate to avoid excessive occupation of the internal space of the annular groove 32. Simultaneously, the baffles 321 are precisely machined into an evenly spaced structure to ensure that their front ends cover all air outlets of the annular groove 32 after installation. Thus, combining the functional characteristics of the multi-layer guide vanes 31 and the micro-nozzles 33, atomization efficiency can be further improved and the uniformity of the liquid distribution can be ensured.

[0039] like Figure 4 As shown, in one embodiment, the micro-nozzles 33 of the forestry pest and disease sprayer of this application are located at the top of the atomizing nozzle 3. The micro-nozzles 33 are arranged in a spiral pattern, which helps to form a multi-directional spray path for the pesticide. To meet the precise control requirements under different working conditions, each micro-nozzle 33 is equipped with an independent adjustable throttle valve 331. The throttle valve 331 is integrated with the micro-nozzle 33, and its main structure consists of an adjustment knob, a valve core, and a valve seat. The valve core can change its opening by rotating, thereby dynamically adjusting the flow rate of the pesticide through the micro-nozzle 33. At the same time, by adjusting the position of the valve core inside the throttle valve 331, the direction of the sprayed pesticide can be further fine-tuned to ensure that the spraying range adapts to complex terrain or the specific distribution of target plants.

[0040] In practical implementation, for example, the throttle valve 331 can be nested inside the corresponding area of ​​the atomizing nozzle 3 and fixed in position using a locking nut. Specifically, the throttle valve 331 has a handwheel on its exterior for easy manual adjustment by the operator, while its interior is connected to the micro-nozzle 33 via a precision guide rod to ensure precise and controllable operation.

[0041] like Figure 3 and Figure 4 As shown, in one embodiment, a protective cover 6 is added to the outside of the atomizing nozzle 3 of a forestry pest and disease sprayer of this application. The protective cover 6 covers the atomizing nozzle 3 and is tightly fitted around it. The protective cover 6 is made of a rigid impact-resistant material, and its surface is designed with an alternating concave and convex structure. This concave and convex structure forms a multi-angle airflow guiding channel, which can adjust and stabilize the surrounding gas flow direction during spraying, thereby further optimizing the uniformity of atomization. This design tightly integrates the protective cover 6 with the atomizing nozzle 3, ensuring that the spraying process is not directly affected by the external environment.

[0042] For example, the protective cover 6 can be installed by machining an annular positioning groove on the atomizing nozzle 3. A matching snap-fit ​​flange is provided on the inner edge of the protective cover 6 to engage with the positioning groove for fixation. Specifically, the use of an elastic material for the fitting ensures the protective cover 6 is secure while facilitating later disassembly, cleaning, and maintenance. The concave-convex design of the protective cover 6 consists of a periodically arrayed hemispherical protrusions and depressions, which can be directly manufactured using a mold forming process to meet usage requirements. This completes the functional integration and installation method of the protective cover 6.

[0043] like Figure 1 As shown, in one embodiment, a connecting frame 4 of a forestry pest and disease sprayer of this application is disposed at the end of the delivery pipe 2 and fixes the atomizing nozzle 3. To increase the spraying range of the pesticide, the connecting frame 4 is equipped with a rotary drive mechanism 7, which is connected to the atomizing nozzle 3. Specifically, the connecting frame 4 has a fitting mounting hole to accommodate the core transmission components of the rotary drive mechanism 7, such as a drive shaft or eccentric wheel structure, and is securely installed by a coupling or fastening bolts. The rotary drive mechanism 7 includes a power output unit and a transmission component; the former may be a micro motor or gearbox combination structure, and the latter is responsible for converting the power into a reciprocating oscillating motion and transmitting it to the atomizing nozzle 3.

[0044] For example, the power output unit in the aforementioned rotary drive mechanism 7 can directly drive a linkage arm assembly to achieve stable operation within the swing angle range. The transmission assembly is installed using a pin-fit method or an embedded interface structure to connect to the atomizing nozzle 3, ensuring accurate execution of reciprocating swing operations and thus meeting the goal of expanding spray coverage. Furthermore, the atomizing nozzle 3, even in this configuration, maintains a certain degree of flexibility with the connecting frame 4, ensuring reliability under actual operating conditions. This arrangement and structural composition contribute to achieving matching mechanical performance and functional synergy.

[0045] like Figure 3 As shown, in one embodiment, the portion of the pesticide delivery pipe 2 of a forestry pest and disease sprayer of this application near the atomizing nozzle 3 is designed as a multi-stage gradually decreasing inner diameter structure 8. This structure achieves the formation of a pressure gradient through progressively smaller internal pipe diameters. Specifically, the multi-stage gradually decreasing inner diameter structure 8 consists of multiple continuous pipe segments with progressively smaller diameters. These pipe segments are seamlessly connected to form a complete channel for transmitting the pesticide solution to the atomizing nozzle 3 in a progressively accelerating manner. This structure is installed in the transition area between the pesticide delivery pipe 2 and the atomizing nozzle 3 to ensure a stable pressure change during the pesticide flow.

[0046] For example, a drug delivery tube segment 2 with multi-stage gradually changing inner diameters can be manufactured using mold processing, and then connected to a conventional drug delivery tube 2 and atomizing nozzle 3. Specifically, the connection between each two stages of the gradually changing segment adopts a smooth transition design to avoid poor drug flow due to increased local resistance. This structure not only ensures that the drug can be delivered smoothly and quickly to the atomizing nozzle 3, but also effectively maintains the pressure stability within the system. At the same time, the end of the gradually changing segment is directly connected to the inlet of the atomizing nozzle 3, ensuring the consistency of its overall performance.

[0047] like Figure 2 As shown, in one embodiment, a specially designed integrated filter device 9 is added to the bottom outlet position of the pesticide storage tank 1 of a forestry pest and disease control sprayer of this application. This filter device is located at the connection between the outlet at the bottom of the pesticide storage tank 1 and the pesticide delivery pipe 2, and is used to prevent particulate impurities from entering the pesticide delivery pipe 2 from the pesticide storage tank 1. Specifically, this filter device consists of a multi-layer filter structure, where each layer uses a different pore size to intercept solid particles of different sizes layer by layer. These filter structures are stacked to form an integrated assembly, and are installed on the pesticide outlet at the bottom of the pesticide storage tank 1 by pressing or welding, thereby ensuring airtightness.

[0048] For example, the filtration device can be assembled by machining a filter holder with nested grooves or threaded interfaces. Precision metal filter screens are placed sequentially inside the filter holder according to their pore size, from coarse to fine, and secured with a cap to enhance overall strength and stability. Subsequently, the integrated filter device 9 is fastened to the bottom outlet of the medicine storage tank 1 using threads, snap-fit ​​connections, or other reliable mechanical means. This achieves the blocking of particulate impurities while maintaining the smooth flow of the medicine solution inside the medicine storage tank 1 to the delivery pipe 2.

[0049] like Figure 2 As shown, in one embodiment, the storage tank 1 of a forestry pest and disease sprayer of this application is equipped with a stirring mechanism 10 for continuously mixing the pesticide solution, which aims to prevent sedimentation or uneven concentration of the pesticide solution during long-term storage or operation intervals. Specifically, the stirring mechanism 10 is located in the inner cavity of the storage tank 1, and its range of action covers the entire pesticide storage area of ​​the storage tank 1, ensuring that the pesticide solution is always kept mixed. For stable installation, the stirring mechanism 10 is usually fixed to the top or side wall of the storage tank 1 by a special bracket, while its drive part is located outside the storage tank 1 for connection to an external power source or power unit.

[0050] The stirring mechanism 10 may specifically include rotating blades and a drive unit. The rotating blades extend into the storage tank 1 and contact the liquid medicine, while the drive unit drives the blades to rotate via a transmission assembly. For example, a small motor can be installed on the side wall of the storage tank 1, and power can be transmitted to the blade shaft via a belt or gear, causing the blades to rotate regularly to continuously stir the liquid medicine. Specifically, the blade design can be adjusted to paddle type, turbine type, or other forms according to actual needs to adapt to different liquid medicine characteristics and working requirements, thereby ensuring the uniformity of liquid medicine mixing and supporting efficient spraying operations.

[0051] like Figure 1 As shown, in one embodiment, a flow monitor 11 is installed in the middle of the pesticide delivery pipe 2 of a forestry pest and disease sprayer according to this application. This component is fixedly installed on the middle section of the pesticide delivery pipe 2 in a nested manner, and its main body is sealed to the outer wall of the pesticide delivery pipe 2. The flow monitor 11 mainly consists of a shell, a sensing unit, and a display module. The sensing unit directly contacts the flow of pesticide liquid passing through the inside of the pesticide delivery pipe 2 and converts its flow rate information into an electrical signal, which is then transmitted to the data processing chip. The data processing chip then transmits the collected information to the display module for intuitive presentation, making it easy for operators to quickly judge and adjust the equipment operating parameters based on the flow data.

[0052] For example, an electromagnetic flowmeter-type flow monitor 11 can be selected and fixed to a specific position on the drug delivery pipe 2 using threaded fastening or a dedicated snap-fit ​​structure. Specifically, the electrodes in the electromagnetic flowmeter are arranged near the inner wall of the drug delivery pipe 2 to detect the flow characteristics of the liquid drug, while ensuring that the external wiring can be easily connected to a display screen for real-time feedback of the monitoring results. In addition, considering that environmental changes may interfere with the measurement accuracy in actual application scenarios, a protective liner can be added between the sensing unit and the drug delivery pipe 2 to further stabilize the monitoring effect.

[0053] like Figure 3 As shown in one embodiment, the connection between the atomizing nozzle 3 and the delivery pipe 2 of the forestry pest and disease sprayer of this application is further provided with a special structural design to improve reliability. Specifically, a waterproof sealing ring 12 is added to the outside of the threaded connection interface between the atomizing nozzle 3 and the delivery pipe 2. This structure prevents leakage at the connection through a physical barrier, ensuring that the output of pesticide from the atomizing nozzle 3 can be continuous and stable. Due to the characteristics of threaded connections, there may be loosening or insufficient tightness during operation. Therefore, the addition of the waterproof sealing ring 12 can effectively avoid the pesticide leakage problem caused by this.

[0054] In terms of specific structural installation, the waterproof sealing ring 12 is directly fitted onto the outer wall of the drug delivery tube 2 and tightly matches the groove on the inner side of the atomizing nozzle 3. This allows the sealing ring to be compressed and deformed when the two are joined, thus achieving a highly reliable sealing effect. For example, the waterproof sealing ring 12 can be made of a corrosion-resistant and drug-resistant elastic material to meet the requirements of long-term operation under different environmental conditions. This technical solution does not affect the original detachable design of the atomizing nozzle 3 and can significantly improve the overall stability of the spraying system. In addition, the shape and size of the waterproof sealing ring 12 need to be carefully designed according to the specific geometric parameters of the end of the drug delivery tube 2 to ensure that its embedding does not affect the normal installation and use of other components.

[0055] In actual operation, when this device is used, the liquid medicine is stored in the storage tank 1, and then the pressure pump 5 is started. The pressure pump 5 provides power to the delivery pipe 2, which transmits the liquid medicine in the storage tank 1 to the atomizing nozzle 3. At the same time, the multi-layered staggered guide vanes 31 inside the atomizing nozzle 3 can enhance the turbulence effect of the liquid medicine, and the outer annular groove 32 can form multiple atomization zones to improve spraying efficiency. The uniformly distributed micro-spray holes 33 on the top can spray the liquid medicine in the form of mist and achieve good distribution uniformity. With the help of the connecting frame 4, the atomizing nozzle 3 can be adjusted to an appropriate angle to cover a wider spraying range and complete the control of pests and diseases in the target area.
