[0031] Furthermore, specific details are provided in the following description to facilitate a thorough understanding of the examples. However, those skilled in the art will understand that the described aspects can be practiced without these specific details.

[0032] like Figure 1As shown, a forest cultivation insecticide device of this application includes a liquid storage tank 1, a diversion valve 2, a liquid delivery pipe 3, and a nozzle assembly 4.

[0033] The storage tank 1 is used to store and supply insecticide solution; the diversion valve 2 is installed at the lower outlet of the storage tank 1 and is responsible for regulating the flow rate of the solution to the nozzle assembly 4; one end of the delivery pipe 3 is connected to the diversion valve 2 and the other end is connected to the nozzle assembly 4 to deliver the solution to the destination; and at the very end of the structure is the nozzle assembly 4, which consists of multiple directional nozzles and can achieve the effect of releasing the solution in an atomized state.

[0034] The storage tank 1 is used to store and prepare the liquid to be sprayed. It is designed with a tapered base that gradually narrows to guide any remaining material towards the output channel, and its internal walls feature spiral drainage grooves, i.e., spiral guide channels 6. This construction not only improves the internal structure of the storage container but also ensures smooth discharge even when handling high-viscosity liquids and reduces problems caused by liquid adhesion to the inner surface. For example, a specific case is manufactured with a predominantly cylindrical shape supplemented by an inverted conical base.

[0035] The diversion valve 2 is mounted at the lower edge interface of the storage tank 1. Its function is to control the dosage distributed from the main source to downstream equipment. Specifically, it can flexibly switch between different working states according to set parameters to manage the flow rate of the pesticide or its on / off state, ensuring the accurate and reliable completion of the operation. The valve body is generally made of a sealing material and formed with a tight-fitting surface through precision machining. It is equipped with a manual operating handle or an electric actuator so that the opening and closing state can be adjusted by manual or automatic control systems to ensure that the required flow rate is accurately delivered to subsequent stages. For example, if workers want to reduce the pesticide dosage per unit time during a forest operation, they only need to turn the handle to reduce the opening degree to achieve the effect of reducing the flow rate, thus adapting to the needs of different task scenarios.

[0036] The infusion tubing 3 is responsible for transporting medication from its storage space to the site of application. It comprises a set of flexible tubing components, allowing for bending and extension in complex environments without affecting normal operation. To prevent damage and leakage due to prolonged exposure to corrosive environments, a high-resistance composite material is used to synthesize its overall structure. The internal surface remains smooth to facilitate stable flow of liquid components and prevent the absorption of impurities that could clog crevices. A real-world application scenario is deploying such a lightweight, durable, flexible, and adjustable hose through dense forests. This hose can easily traverse between trees to reach every designated location within the target area, efficiently covering the entire forest area.

[0037] The nozzle assembly 4 is located at the very front of the entire conveyor chain. It integrates a varying number of directional control nozzles arranged in a specific pattern. These nozzles work together to produce a fine, diffused chemical spray that covers the surface of the plant's branches and leaves. Each small nozzle often incorporates an airflow mixing or centrifugal rotation mechanism, promoting the uniform splitting and expansion of liquid particles, significantly enhancing the coverage area and demonstrating excellent pest control results. For example, when controlling specific types of insect pests, the operating mode can be rationally selected based on their activity patterns and habitat characteristics, ensuring that the sprayed micro-droplets reach the hiding places of the insect eggs precisely.

[0038] This forest-cultivation insecticide system reduces pesticide residue and enhances the output stability of substances of various viscosity levels. By introducing a storage tank with a uniquely contoured bottom and utilizing a rotating indentation guide line, the synergistic effect greatly promotes internal drug flow efficiency, limits the frequency of residue occurrence, and maintains good operational performance under continuous operating conditions. For highly viscous products that are difficult to empty completely, the conical bottom structure combined with the screw groove design significantly improves the thoroughness of discharge.

[0039] In one embodiment, the bottom of the storage tank 1 of the forest cultivation insecticide device of this application is configured as a conical bottom 5. The apex angle of the conical bottom 5 is set in the range of 30 to 60 degrees. This design optimizes the concentrated guiding performance of residual pesticide solution. By selecting an appropriate angle, not only can the residual pesticide solution flow more effectively towards the lower outlet direction of the storage tank 1, but also the problem of stagnation is avoided under the condition of large pesticide solution flow.

[0040] Practice has shown that this apex angle range ensures stable flow of the liquid regardless of whether the flow rate is high or low, and significantly reduces the amount of liquid remaining inside the storage tank 1. At the same time, this design guarantees smooth discharge of liquids of varying viscosities without the problems of accumulation or poor flowability caused by an inadequate internal wall structure.

[0041] For example, to achieve this, the conical bottom 5 is manufactured with a precise angle, gradually narrowing from top to bottom until it approaches the minimum outlet diameter. This can be precisely controlled through mold processing, casting, and other methods. Furthermore, the requirements of other internal components are considered during the manufacturing of the conical bottom 5; for instance, the design of the spiral guide channel 6 must smoothly transition with the conical bottom 5, ensuring a seamless surface structure between them. This guarantees that the entire device exhibits excellent performance characteristics during operation, whether in static storage or dynamic spraying phases.

[0042] In one embodiment, the diversion valve 2 of the forest cultivation insecticide device of this application is made of stainless steel to ensure good corrosion resistance and mechanical strength in harsh environments. The diversion valve 2 includes a multi-stage adjustable channel structure 7 (see...). Figure 4 These channels can flexibly adjust their opening degree and orifice size according to the different viscosities of the medicine, thereby achieving precise control of the medicine flow rate. The specific adjustment function relies on the graded design of the channels and their relative movement, which is achieved by manually or electrically turning the knob to change the relative position between the valve core and the valve seat.

[0043] For example, in one specific instance, the diversion valve 2 is fixedly installed at the lower outlet of the storage tank 1. When the liquid medicine flows from the storage tank 1 into the diversion valve 2, after being dynamically adjusted by pre-set or multi-stage channels, it is evenly transmitted to the infusion pipe 3 according to a predetermined flow distribution ratio and finally sprayed out. Precise flow control in this process is achieved through the complex but carefully designed multi-stage channels inside the valve. The channel structure is automatically adjusted or manually adjusted by the operator according to the set parameters to adapt to the different characteristics of various liquid medicines.

[0044] In one embodiment, the infusion tube 3 of the forest cultivation insecticide device of this application has a built-in elastic layer 8 (see...). Figure 3 By incorporating this special elastic layer 8 structure on the inner wall of the infusion tube 3, smoother drug delivery is ensured. Especially for higher concentrations of pesticides, the elastic layer 8 reduces the residence time of the drug within the pipe and effectively prevents blockages caused by high viscosity. The elastic layer 8 fits tightly against the inner surface of the infusion tube 3, providing enhanced corrosion resistance and deformation resistance without affecting the overall pipe dimensions, adapting to different pesticide properties. This elastic layer 8 design not only improves system stability but also reduces maintenance costs caused by pesticide residue or blockages.

[0045] Specifically, suitable elastic materials, such as biocompatible silicone rubber or modified TPU, can be selected as the base material for the elastic layer 8. These materials possess excellent chemical stability. Subsequently, the selected material is pre-treated and heated to a pliable state according to predetermined dimensions, then evenly wrapped inside a specially designed mold. This inner liner assembly is then inserted into the outer layer of the pre-processed but not yet finalized infusion tube 3, allowing it to cool and solidify naturally to form a tightly integrated structure. During installation, this infusion tube 3 with its specially designed inner layer directly replaces standard tubing and is installed between the outlet of the diversion valve 2 and the connection point of the nozzle assembly 4. Its installation position is located in the transition area between the two, ensuring a tight seal at both ends to avoid leakage risks.

[0046] Furthermore, it should be mentioned that in practical applications, to better suit different environmental conditions, the thickness of the elastic layer 8 can be appropriately adjusted according to the specific operational scenario requirements, or more targeted functional polymers can be selected to meet diverse needs. For example, in extreme weather conditions or in work environments requiring continuous pesticide application for specific pest types, the protective function of the elastic layer 8 can be further enhanced by adding appropriate additives to improve its wear resistance, temperature resistance, and corrosion resistance. However, these optimization measures will not change the basic description above regarding the integration method and technical implementation of the elastic layer 8 and the infusion tube 3.

[0047] In one embodiment, the directional nozzle in the nozzle assembly 4 of the forest cultivation insecticide device of this application is sintered from high-density metal powder. The directional nozzle made of this material possesses excellent corrosion resistance and maintains high operational reliability and accuracy during long-term use. The material properties of the high-density metal powder ensure that the directional nozzle can withstand the influence of complex external environmental factors, especially against highly chemically corrosive insecticides or extreme outdoor climatic conditions. Since the nozzle atomizes the pesticide and is in direct contact with the atmosphere, this feature greatly improves the overall durability of the device.

[0048] For example, in terms of specific technical implementation, the directional nozzle is manufactured by forming it using a precision mold and then undergoing high-temperature sintering and curing. It is installed at the end of the infusion tube 3, directly facing the target pest habitat for uniform spraying of the pesticide. Multiple nozzles form an array structure, each operating independently yet collaboratively. Furthermore, the directional nozzle is tightly fixed to the nozzle assembly 4 using special connectors, and its internal channels are designed in a streamlined shape, facilitating smooth pesticide flow and generating appropriate centrifugal force during spraying to form fine droplets. This connector design also ensures a smooth and natural transition between the infusion tube 3 and the nozzle.

[0049] In one embodiment, the nozzle assembly 4 of a forest cultivation insecticide device of this application is provided with an anti-drip structure 9 located behind each directional nozzle. During actual operation, this structure can quickly seal the outlet after spraying, thereby preventing residual liquid from dripping and causing waste or environmental pollution. This design improves the overall performance and efficiency of the system by precisely controlling the liquid flow after spraying. The presence of the anti-drip structure 9 not only improves the accuracy and environmental friendliness of the pesticide application but also simplifies the equipment cleanup process after operation.

[0050] Specifically, the anti-drip structure 9 is installed after each directional nozzle, inside the nozzle assembly 4 near the nozzle, rather than in a location easily damaged by the outside. This design ensures that even if residual liquid remains at the nozzle tip at the end of the spraying operation, it will not continue to fall due to gravity or other factors. From a component perspective, it consists of a quick-response valve body and a sealing gasket working together to create a sealing effect. The quick-response valve body can immediately close the channel when triggered by an external command or when the liquid supply stops; the sealing gasket is tightly fitted around the connection between the valve body and the nozzle, ensuring an absolute seal at the joint to completely prevent dripping.

[0051] For example, when the system receives a command to stop spraying or the sensor detects that the liquid level in the storage tank 1 is below the threshold, the electrical signal is quickly transmitted to the fast-response valve in each anti-drip structure 9, prompting the latter to immediately start the shutdown procedure, and using the internal spring pre-compression mechanism to make the sealing gasket tightly pressed near the outlet, eliminating the possibility of residual liquid leakage in any form.

[0052] In one embodiment, return to reference Figure 1 The storage tank 1 of the forest cultivation insecticide device of this application is equipped with a heating device 10 at its bottom. This design aims to improve the adaptability and reliability for use in cold regions. The storage tank 1 is the core component for storing and supplying insecticide solution. Since the viscosity of different types of insecticide solutions may increase significantly in low-temperature environments, thus affecting their flowability and leading to poor delivery or even failure to spray smoothly, maintaining the temperature stability inside the storage tank 1 under severe cold conditions is crucial. The heating device 10 continuously supplies appropriate heat to the bottom of the storage tank 1, preventing the internal solution from freezing or becoming too viscous due to a sudden drop in external temperature, ensuring that the solution flows out at an ideal viscosity and is smoothly transported to each nozzle assembly 4 along a predetermined path.

[0053] The heating device 10 is installed on the outer bottom surface of the liquid storage tank 1 using a contact heating scheme, with a high-efficiency heat transfer medium filling layer between them to ensure efficient energy transfer. Specifically, the heating device 10 is typically composed of an electric heating coil or a heating element, and its output power is controlled by a temperature control unit to achieve precise constant temperature management. The temperature control system monitors external meteorological parameters and automatically adjusts its working state; when the outside temperature is lower than a set threshold, the heating function is automatically activated.

[0054] For example, in a practical application scenario, the heating effect can be further enhanced by combining the spiral guide channel 6 with the heating device 10. As the liquid flows from the conical bottom 5 towards the outlet, it gradually heats up in the preheating zone to reach a suitable flow state, allowing the equipment to maintain optimal operation even in extremely cold weather. At the same time, this heating design does not interfere with the spatial arrangement and connection of the infusion pipe 3 and other auxiliary structures, ensuring the consistency and compactness of the overall structure.

[0055] In one embodiment, such as Figure 2 As shown, the top of the liquid storage tank 1 of the forest cultivation insecticide device of this application is equipped with a transparent viewing window 11 to ensure that the user can intuitively view the liquid volume without affecting the operational safety of the device. This design ensures both ease of use and the safety and reliability of the device in complex environments.

[0056] The liquid storage tank 1 is one of the key components of the entire system. The viewing window added to its top is made of high-quality transparent material, such as weather-resistant acrylic glass. This material has excellent light transmittance and high strength, maintaining stable performance in harsh environments for extended periods, while also possessing sufficient corrosion resistance to the liquid. By selecting a suitable installation location and employing appropriate techniques, the viewing window is fixed to the top surface of the liquid storage tank 1 and tightly integrated with the existing structure, thus avoiding any gaps or weak points that could potentially affect the safety of the equipment. To ensure sealing and overall aesthetics, appropriate professional sealant or other forms of reinforcement are applied at the joint between the two. The presence of this viewing window allows operators to monitor the internal liquid level in real time, enabling timely replenishment of liquid and maintaining the continuous operational efficiency of the system.

[0057] Specifically, the viewing window can be installed on the top surface of the liquid storage tank 1 via mechanical embedding or chemical bonding, ensuring good compatibility with the main material of the liquid storage tank 1. With mechanical embedding, a matching groove-shaped edge structure can be pre-designed on the top of the liquid storage tank 1 to accommodate and secure the transparent material. Chemical bonding requires precise mixing of the special adhesive and application area to ensure a durable bond without damaging the integrity and sealing performance of the liquid storage tank 1. This design balances practicality and safety, meeting the high standards required for equipment in forest cultivation environments.

[0058] In one embodiment, continue to refer to Figure 1The storage tank 1 of the forest cultivation insecticide device of this application has reinforcing ribs 12 on its side wall. These reinforcing ribs 12 are longitudinal or spiral ribs, evenly distributed on the outer or inner surface of the storage tank 1. By increasing the thickness and strength of the side wall of the storage tank 1, the overall structural stability is improved. This design reduces the shaking problem of the storage tank 1 caused by vehicle movement or other external vibrations. Specifically, because the reinforcing ribs 12 can disperse stress concentration, they prevent plastic deformation or cracks in the side wall during long-term use, further ensuring the service life and safety performance of the device.

[0059] Furthermore, the reinforcing ribs 12 not only provide structural support for the liquid storage tank 1, but also significantly reduce internal turbulence caused by liquid sloshing. For example, when the liquid storage tank 1 is filled with liquid, the sloshing during movement causes the liquid to impact the tank wall and generate significant ripple forces, leading to the formation of internal eddies. After adding the reinforcing ribs 12, this impact force and accompanying turbulence are significantly reduced, making the liquid inside the liquid storage tank 1 more stable and reducing the probability of residue. In practice, the reinforcing ribs 12 can be integrally molded with the tank wall during the manufacturing process of the liquid storage tank 1 through injection molding, or prefabricated reinforcing rib 12 components can be installed on appropriate positions on the outside of the liquid storage tank 1 using mechanical fixing or other methods in the post-processing stage to ensure a tight fit to the tank body and achieve the reinforcement effect.

[0060] In one embodiment, see specific reference. Figure 3 The spiral guide channel 6 of the forest cultivation insecticide device of this application is coated with a superhydrophobic coating 13, which significantly reduces the wetting ability of the pesticide solution on the channel surface. By optimizing this surface property, it is ensured that the pesticide solution can flow rapidly to the outlet, effectively avoiding pesticide solution sticking and stagnating on the inner wall of the channel, and improving the outflow efficiency of the entire system. The design of this device makes full use of the unique properties of superhydrophobic materials, thereby improving the key links of pesticide solution delivery and release.

[0061] Specifically, this coating covers the entire outer surface of the spiral guide channel 6 on the inner wall of the liquid storage tank 1, completely adhering to the base structure on which it is installed, forming a seamless protective layer and flow guiding mechanism. It does not affect the established connections and operational coordination between other components, ensuring that the nozzle assembly 4 receives a stable and efficient supply of medicine from the liquid storage tank 1. Since the conical bottom 5 and the spiral guide channel 6 already provide a rational design for the internal space, the addition of a superhydrophobic coating 13 further facilitates the effective transmission of various types of medicines, further enhancing the device's adaptability to different types of agents.

[0062] For example, to technically achieve this feature, the superhydrophobic coating 13 can be applied using mature processes such as spraying, dipping, or physical vapor deposition (PVD) to ensure its uniform and dense distribution across the entire outer surface of the guide channel. This process must be precisely controlled to achieve the desired contact angle and rolling performance, while ensuring that the additional coating does not alter the infusion path, maintaining the functional stability of components such as the diversion valve 2 and the infusion tube 3, as well as the compactness and integration of the original design. Furthermore, selecting a coating that is highly compatible with the spiral guide channel 6 and resistant to chemical corrosion as the primary material is also a key factor in ensuring stable operation over long periods.

[0063] In one embodiment, the storage tank 1 of the forest cultivation insecticide device of this application is provided with a spiral guide channel 6, and a guide spike structure 14 is added to its end. The guide spike structure 14 is designed at the end of the spiral guide channel 6 of the storage tank 1, which can ensure that even the smallest amount of residual pesticide can be efficiently pushed to the lower outlet, and minimize the possibility that the contents of the storage tank 1 are not completely discharged.

[0064] Through this special design, the storage tank 1 can more thoroughly squeeze out any remaining liquid, especially effective for the last sliver of liquid that tends to linger in corners and on walls where it is difficult to flow. The presence of guide spikes enhances the system's effective management of agents with different types and viscosity characteristics, further improving resource utilization during operation and reducing material waste caused by residual liquid. Furthermore, when the storage tank 1 is about to be emptied, this structure ensures stable and uniform pressure transmission to every point, allowing the spraying operation to be completed smoothly without any adverse effects.

[0065] To achieve the aforementioned features, a technical solution could be implemented by using a small component with a pointed structure made of a hard material such as stainless steel or high-density plastic, and then firmly fixing it to the bottom region of the liquid storage tank 1. Specifically, during assembly, it is necessary to ensure that the end of the spiral guide channel 6 is tightly connected to the newly added guide spikes and that both are on the same straight line. This ensures that there is not too much resistance as the liquid flows from the liquid storage tank 1 to the outside, and also ensures that all residual liquid can pass smoothly through this structure and ultimately be output from the designated location.

[0066] In actual operation, when this device is in use, the storage tank 1 stores the insecticide solution and provides a stable supply. The flow rate of the solution is regulated by a diversion valve 2 installed at the lower outlet of the storage tank 1, precisely controlling the amount of solution flowing to the nozzle assembly 4 as needed. The delivery pipe 3 connects the diversion valve 2 and the nozzle assembly 4, ensuring the safe delivery of the regulated solution to the nozzle assembly 4. The nozzle assembly 4, located at the end of the delivery pipe 3, consists of multiple directional nozzles that release the solution in an atomized state, ensuring uniform distribution and effective coverage of the target area. The bottom of the storage tank 1 is conical, gradually narrowing to guide residual solution to flow towards the outlet. A spiral guide groove 6 is wound around the inner wall to promote smooth flow and reduce stagnation. This design optimizes the internal space of the storage tank 1, ensuring stable discharge performance when handling solutions of different viscosities and reducing residual solution.

[0067] The above description is the preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this invention, and these improvements and modifications should also be considered within the scope of protection of this application.
