[0026] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings. The illustrative implementation methods and descriptions of the embodiments of this disclosure are only used to explain the embodiments of this disclosure and are not intended to limit the embodiments of this disclosure.

[0027] like Figures 1-5 As shown, a wheat planting pesticide preparation device of this application includes a pesticide storage tank 1, an adjusting bracket 2, a pesticide dosing pipe 3, an adjustable dosing head 4, and a drip collection box 5. The components work together to ensure that the pesticide delivery and preparation process is efficient and accurate.

[0028] The medicine storage tank 1 is the core container component of this device, used to store the prepared medicine solution. The medicine storage tank 1 features a sealed design, and its top cover is removable for cleaning and refilling. It typically has internal shock-absorbing baffles or stabilizing mechanisms to ensure the medicine solution does not shake violently during transportation and pouring. To meet different capacity requirements, the medicine storage tank 1 can adopt a modular structure with a drain port at the bottom for easy removal of excess liquid. For example, transparent graduations can be installed on the outside of the medicine storage tank 1 to accurately monitor the inventory level.

[0029] The adjusting bracket 2 is fixed below the medicine storage tank 1, mainly used to support the medicine storage tank 1 and adjust its height within a certain range to adapt to the operating requirements of different environments. Its main structure consists of multiple cross support rods, which can be quickly adjusted and kept fixed by adjusting the hinge assembly. In actual operation, the extension and retraction of the support rods can be changed by manually rotating the screw-on handle, so that the medicine storage tank 1 is at a suitable height, facilitating smooth connection and dosing operations.

[0030] The dosing pipeline 3 is a key conveying device running through the entire system, and it is connected to the liquid storage tank 1 via a sliding connection. This dosing pipeline 3 forms a sliding guide system with the liquid storage tank 1 using limiting blocks 22. The limiting blocks 22 restrict the range of motion while ensuring the accurate and unbiased trajectory of the dosing pipeline 3. To prevent external impurities from entering or internal liquid leakage during adjustment, telescopic sealing covers 23 that move with the dosing pipeline 3 are installed at both ends of the limiting blocks 22, keeping the entire liquid storage tank 1 airtight. Technically, the telescopic sealing covers 23, made of flexible material, can be used in conjunction with a multi-ring clamping device to firmly enclose the limiting blocks 22, ensuring effective isolation from air contact even with frequent movement.

[0031] The adjustable dosing head 4 is located at the end of the dosing pipeline 3 and is responsible for precisely releasing the required volume or flow rate of pesticide into the pesticide storage tank 1. This component has horizontal sliding, vertical lifting, and angle adjustment functions, with independent yet coordinated control in all three dimensions. Specifically, the horizontal sliding component (such as the combination of rack 15 and gear 16) allows for flexible adjustment to a suitable position on a flat surface; the vertical lifting component (such as a ball screw drive) enables fine-tuning of the height to ensure consistent contact points; furthermore, the built-in drive mechanism changes and locks the angle of the output end, directing the spray path towards the optimal area. This complex combination mechanism greatly enhances the precision of control, thereby reducing the possibility of pesticide loss due to misalignment or splashing.

[0032] The drip collection box 5 is installed directly below the adjustable dosing head 4 to collect small amounts of liquid that may accidentally drip during the drug preparation stage. It is securely attached to the vicinity of the dosing pipe 3 via a connecting structure. Its shape is designed to facilitate drainage with a sloping ramp, and the bottom outlet can be further connected to a waste liquid treatment system. In practical applications, if excessive residual drug liquid is detected, the sensor inside the collection box sends data to the controller to trigger an alarm or automatically remove excess contents, thus maintaining environmental hygiene and preventing the waste of valuable resources.

[0033] Regarding how to reduce spillage and waste during drug preparation: The aforementioned optimization measures comprehensively address potential technical challenges. Firstly, an adjustable dosing head 4 with omnidirectional adjustment capabilities is employed, dynamically tracking and precisely positioning the target inlet. This significantly reduces the inaccuracy issues associated with traditional fixed nozzles, lowering the risk of overflow. Secondly, a drip collection box 5, specifically designed for collecting fine droplets, acts as a protective mesh, preventing any leakage of even a tiny dose. Furthermore, the entire process operates in a fully enclosed state, fundamentally achieving the ideal results of improved efficiency and drug conservation.

[0034] like Figure 1 As shown, in one embodiment, the pesticide storage tank 1 of a pesticide dispensing device for wheat cultivation according to this application is provided with a transparent observation window 6. The transparent observation window 6 is installed on the outside of the pesticide storage tank 1 and is securely connected to the pesticide storage tank 1 via a sealing element to ensure the overall sealing performance of the device. The transparent observation window 6 is made of corrosion-resistant material, which can resist the erosion of pesticide components, while also possessing high light transmittance. To accurately monitor the remaining pesticide level, the height of the transparent observation window 6 covers the main capacity range of the pesticide storage tank 1 and is marked with scale lines for quantitatively displaying the pesticide level.

[0035] For example, the transparent observation window 6 is installed on the wall of the medicine storage tank 1 using an embedded method. Specifically, the edge of the transparent observation window 6 that contacts the medicine storage tank 1 is first processed into a flat surface, and then high-strength waterproof adhesive is applied around it for sealing before fixing, ensuring the stability and leak-proof characteristics of the transparent observation window 6 during long-term use. In the actual technical implementation process, acrylic or tempered glass can be selected as the material for the transparent observation window 6, and it can be installed and fixed by combining epoxy resin adhesive and mechanical fastening. At the same time, to ensure the accuracy of the scale, a scale can be pre-printed on the outer surface of the observation window and correlated with the internal capacity ratio of the storage tank, thereby realizing visual real-time monitoring.

[0036] like Figure 3 As shown, in one embodiment, the bottom of the pesticide storage tank 1 of the pesticide dispensing device for wheat cultivation in this application is provided with an inclined structure 7. This special structural design allows the pesticide stored in the storage tank 1 to naturally converge to one side, thus facilitating the discharge of the pesticide from the outlet. The purpose of this design is to ensure that the pesticide dispensing device minimizes pesticide residue in the storage tank 1 during operation, while ensuring a smooth flow path throughout the entire dispensing process. The inclined bottom of the pesticide storage tank 1 does not affect the installation position or use of other components; for example, the positional relationship between the inclined bottom surface and the dosing pipe 3 remains unchanged.

[0037] For example, the inner bottom wall structure of the medicine storage tank 1 with a fixed tilt angle can be manufactured using a molding process, with the lowest point correspondingly located on the side near the liquid outlet. Specifically, the angle formed by the tilted bottom surface and the horizontal direction can be set within a reasonable range to balance the efficiency of medicine collection and space utilization, while avoiding interference with the installation of components such as the drip collection box 5. This structure matches well with the positions of the dosing pipe 3 and the drip collection box 5, and does not affect the overall operational stability of the device.

[0038] like Figure 3 As shown, in one embodiment, the adjusting bracket 2 of the wheat planting pesticide dispensing device of this application adopts an integral structure composed of multiple telescopic rods 8, wherein each telescopic rod 8 can move relative to each other and can be fixed in different positions. These telescopic rods 8 achieve vertical height changes through threaded connections, nesting, etc., and are locked by fixing bolts 9. The fixing bolts 9 are tightened after passing through the corresponding holes on each telescopic rod 8, thereby ensuring that the height after extension and retraction can be stably maintained at the set value. This design makes the distance between the pesticide dispensing head and the crop more flexible and adjustable, meeting diverse operational needs.

[0039] For example, one end of the telescopic rod 8 can be connected to a fixed base under the medicine storage tank 1, while the other end can move freely to adapt to terrain conditions. Specifically, positioning grooves or protrusions can be pre-set between adjacent telescopic rod sections 8 to assist in locking the operation process, while the adjusting bracket 2 itself is tightly fitted to the medicine storage tank 1 by a fixing device, ensuring the structural safety and reliability of the entire equipment during operation.

[0040] like Figure 1 As shown in one embodiment, the technical feature of a wheat-growing pesticide dispensing device of this application is that the pesticide storage tank 1 is equipped with a specific device to ensure the accuracy of the entire pesticide dispensing process. Specifically, in the device, a level detection component is installed on the surface of the pesticide storage tank. The function of this component is to assist the user or control system in determining the degree of inclination of the plane on which the pesticide storage tank is located in real time. Considering that the support may change its state due to uneven ground or other factors, this detection component provides key data support for adjusting the position of the pesticide storage tank. At the same time, its installation method needs to form a stable connection with the storage tank without affecting the normal operation of the storage tank itself and other components.

[0041] For example, the level 10 can be fixed to the top of the medicine storage tank near the edge using an embedded or external method, with its detection surface coplanar with the horizontal reference plane of the medicine storage tank. Specifically, the level 10 can be connected to the medicine storage tank by means of adhesive, screw tightening, or clip fixing, thereby ensuring stable operation during the movement or adjustment of the entire device. In addition, the level 10 also has a reserved interface to feed back information to an external control unit or allow direct reading by the user, providing an accurate reference for the final adjustment operation.

[0042] like Figure 4 As shown, in one embodiment, a flow controller 11 is installed on the dosing pipe 3 of a wheat planting pesticide dispensing device of this application to precisely control the flow rate and volume of the pesticide solution. By installing the flow controller 11 at an appropriate location on the dosing pipe 3, accurate control of the pesticide solution transmission process is ensured. Specifically, the flow controller 11 is installed in a section between the dosing pipe 3 and the pesticide storage tank 1, and is tightly connected to ensure structural integrity and the continuity of pesticide solution transmission. This design allows the amount of pesticide solution released by the dosing head to be dynamically adjusted according to actual needs, further reducing the occurrence of overflow problems and improving the operational accuracy of the pesticide dispensing device.

[0043] The flow controller 11 can consist of an electronic regulating module and a mechanical valve, such as a control valve structure driven by electricity or pneumatics, used in conjunction with a flow sensor. The flow rate is precisely controlled by adjusting the valve opening through a signal feedback system. During assembly, the flow controller 11 is sealed to the dosing pipeline 3, with both ends firmly fixed to prevent leakage of the chemical solution, while not affecting the overall functionality of the structure. This configuration technically ensures the stability of flow rate and flow regulation, thereby improving overall performance.

[0044] like Figure 4 As shown, in one embodiment, the horizontal sliding assembly of a wheat planting pesticide dispensing device of this application is a core component for achieving rapid horizontal positioning of the adjustable dosing head 4. Specifically, the horizontal sliding assembly mainly consists of a guide rail 12 and a slider 13. The guide rail 12 is firmly installed at a designated position on the adjusting bracket 2, serving a guiding function, while the slider 13 forms a movable connection with the guide rail 12, ensuring that the slider 13 can slide freely along a predetermined trajectory on the guide rail 12. To fix the position of the slider 13, a knob screw 14 is provided on one side of the slider 13 and matches it. By manually tightening or loosening the knob screw 14, the slider 13 can be locked or released, completing the precise positioning operation.

[0045] For example, assembly can be completed as follows: The guide rail 12 is horizontally fixed to the surface of the adjusting bracket 2, and the slider 13 is engaged within the guide rail 12 to ensure smooth movement. Next, the knob screw 14 is installed and adjusted to control the fixed position of the slider 13. During operation, the adjustable dosing head 4 moves precisely horizontally using a combination of the slider 13 and the guide rail 12, while being reliably locked using the knob screw 14. In this way, the entire assembly provides stable working conditions for the dosing process.

[0046] like Figure 4 As shown, in one embodiment, the vertical lifting assembly of a wheat planting pesticide dispensing device of this application comprises a gear 16 and a rack 15. The gear 16 and rack 15 are meshed, allowing the rack 15 to move vertically along its axial direction when driven. This vertical lifting assembly is located near the adjustable dosing head 4, and the gear 16 and motor 20 are connected to the adjusting bracket 2 via a suitable fixing structure. Simultaneously, the rack 15 is associated with the dosing pipe 3 or the dosing head. Thus, the vertical height can be adjusted by changing the position of the rack 15 to drive the adjustable dosing head 4.

[0047] Furthermore, the motor 20, serving as the driving force source for the gear 16, is mounted at an appropriate position on the adjusting bracket 2, enabling precise control of the rotation amount and direction of the gear 16. The transmission relationship between the gear 16 and the rack 15 ensures stable changes in the vertical height of the dosing head, adapting to the requirements of the drug addition position under different working conditions.

[0048] For example, when the motor 20 is started, the gear 16 rotates a certain angle according to the set parameters, and the rack 15 moves a predetermined distance axially in sync, thereby causing the component fixed to the rack 15 to change its spatial position. Specifically, in this process, the rack 15 directly acts on the adjustable dosing head 4, realizing precise control of the vertical positioning accuracy of the dosing head, and cooperating with the horizontal sliding component and the drive mechanism to complete the all-round position adjustment task.

[0049] like Figure 2 and Figure 3 As shown, in one embodiment, the drive mechanism of a wheat planting pesticide dispensing device of this application consists of a servo motor 17 and a support shaft 18. These two components work together to calibrate the direction and adjust the angle of the adjustable pesticide dispensing head 4. The servo motor 17 is installed at or near the end of the vertical lifting assembly via a specific structure, ensuring smooth operation and transmitting torque to the support shaft 18. The support shaft 18 is connected to the mounting location of the adjustable pesticide dispensing head 4 via bearings or other rotating supports. The servo motor 17 drives the support shaft 18 to rotate, thereby changing the spatial orientation of the adjustable pesticide dispensing head 4 and maintaining a stable angle setting, preventing pesticide spillage due to position changes.

[0050] This adjustment mechanism allows for precise control of the direction of the liquid output from the adjustable dosing head 4. Specifically, the servo motor 17 is fixed to its corresponding support position using a mounting plate, and its output shaft is combined with the support shaft 18 via a keyway, coupling, or similar connection structure. For example, during assembly, the mounting base of the servo motor 17 is bolted to a designated component of the frame, while the support shaft 18 passes through the connection point and is tightly coupled to the adjustable dosing head 4. This structure allows the support shaft 18 to receive the rotational motion generated by the servo motor 17 and efficiently convert this motion into spatial orientation adjustment of the adjustable dosing head 4.

[0051] like Figure 2 As shown, in one embodiment, the drip collection box 5 of the wheat planting pesticide application of this application is provided with a return nozzle 19 on its side, which allows excess pesticide solution to flow back into the pesticide storage tank 1. To achieve this function, the return structure consists of an opening formed on the side wall of the drip collection box 5 and a corresponding connecting component. By proper installation, the opening is connected to a hose, allowing the collected pesticide solution to be transported back to the pesticide storage tank 1 along a preset path, ensuring the effective utilization of the pesticide solution during device operation. In a specific structure, the opening is located near the bottom of the drip collection box 5 for more comprehensive pesticide solution recovery.

[0052] Specifically, the hose can be securely installed to the opening using a standard interface, ensuring a sealed connection to prevent liquid leakage. For example, the hose can be fixed to the opening of the drip collection box 5 using threads or snap-fit ​​methods, with gaskets added to enhance the reliability of the connection. Furthermore, the other end of the hose extends to a suitable location inside the medicine storage tank 1, ensuring smooth flow of the medicine into the storage area and fulfilling the closed-loop design requirements. With this arrangement, the connections between components are tight and logically clear, effectively meeting the technical requirements.

[0053] like Figure 2 As shown, in one embodiment, the dosing pipe 3 and the drip collection box 5 of the wheat planting pesticide application are fixedly connected by a detachable connection method. Specifically, a quick-release connector 21 is provided at one end of the dosing pipe 3 near the drip collection box 5. This structure includes a threaded interface, which allows for quick installation or disassembly of the two components through threaded engagement. This design ensures easier operation of the entire device when maintenance or cleaning is required, while ensuring that the sealing and stability between the components are not significantly affected by repeated disassembly and assembly. The introduction of the quick-release connector 21 not only facilitates thorough cleaning or maintenance of the inside of the dosing pipe 3 by technicians, but also allows the drip collection box 5 to be easily removed for disposal of overflow or collected liquid.

[0054] For example, a standard connecting pipe section with external threads can be designed at the end of the dosing pipe 3, and a matching internal thread interface can be made at the opening edge of the drip collection box 5 at the top, thereby forming a stable connection by tightening. At the same time, an additional sealing ring can be installed at the connection point to enhance waterproofing. This not only clarifies the relative positional relationship between the two components but also ensures the safety and reliability of the connection.

[0055] In actual operation, when this device is in use, the liquid storage tank 1 is used to store the liquid to be prepared and is supported and height-adjusted by the adjustable bracket 2 to adapt to different dosing needs; then, the liquid storage tank 1 is kept sealed by sliding the dosing pipe 3 and using the limiting block 22 and the telescopic sealing cover 23 on it, thereby ensuring no leakage during the dosing process; then the position of the adjustable dosing head 4 is adjusted, the horizontal sliding component is used to adjust its left and right position, the vertical lifting component is used to change its vertical height, and the drive mechanism is used to fix the angle to achieve precise release of liquid; during this process, the drip collection box 5 is placed directly below the adjustable dosing head 4 and connected to the dosing pipe 3 to collect any possible liquid drips, avoiding waste or environmental pollution.
