Description

Technical Field

[0001] This utility model relates to the field of agricultural plant protection equipment technology, and in particular to a micro pesticide spraying device for pest control. Background Technology

[0002] Integrated pest management is a key link in ensuring crop yield and quality. Traditional manual pesticide spraying has the following technical defects: First, it is inefficient and the daily coverage area is small; second, it is labor-intensive, and operators need to carry 15-20 kg pesticide tanks for continuous operation; most importantly, manual spraying is difficult to achieve precise application of pesticides, resulting in insufficient pesticide utilization and poor uniformity of droplet deposition.

[0003] While existing automated spraying equipment has improved application scope and operational efficiency to some extent, significant technical bottlenecks remain: limited range (some equipment has limited spray boom adjustment range, insufficient steering flexibility, and poor spraying effect); insufficient accuracy (some equipment relies on GPS, which may misjudge pest locations in complex environments, and image-based pest identification is easily interfered with, resulting in low detection rates); pesticide waste and environmental pollution (spraying along fixed routes cannot dynamically adjust the dosage according to pest density, leading to insufficient or excessive application in some areas, and pesticide drift into non-target areas also causes environmental pollution). These problems affect the pest control effectiveness, economy, and sustainability of automated spraying equipment. Utility Model Content

[0004] Objective: In order to overcome the shortcomings of the existing technology, this utility model provides a micro pesticide spraying device for pest control, which can be used in conjunction with automated machinery to achieve precise pesticide application. It has a simple structure and high pest control efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] This utility model provides a miniature pesticide spraying device for pest control, including a pesticide box, a mounting plate, and a spraying assembly;

[0007] The medicine box is mounted on a mounting plate, with a medicine outlet at the bottom and one or more medicine inlets at the top covered with a medicine inlet cap for storing liquid medicine;

[0008] The mounting plate is a rigid structure used to install the medicine box onto automated machines;

[0009] The spraying assembly is detachably connected to the medicine outlet at the bottom of the medicine tank for spraying liquid medicine; and the spraying assembly includes an angle adjustment mechanism for adjusting the horizontal direction of the liquid medicine sprayed by the spraying assembly.

[0010] It should be noted that the automated machines include agricultural plant protection equipment such as intelligent pest control robots. In some embodiments, the medicine tank is made of corrosion-resistant high-strength plastic with a large volume, reducing the frequency of adding medicine. The medicine inlet and medicine inlet cover support rapid medicine replenishment, and when multiple medicine inlets are set, it can support a variety of medicine mixing systems. It can be connected to the intelligent medicine dispensing module of the automated machine to automatically adjust different medicine ratios, with high scalability and strong intelligent potential.

[0011] The medicine box is mounted on the automated machine via a mounting plate. In some embodiments, the rear of the medicine box is wrapped around the mounting plate, which serves as a structural load-bearing component between the medicine box and the automated machine, providing rigid support. The wrap-around design distributes the weight of the medicine box, reducing the transmission of vibrations when the automated machine is in motion.

[0012] In some embodiments, the spraying assembly further includes a spraying pump, a regulating valve, a connector, a delivery pipe, and a nozzle;

[0013] The spray pump is connected to the outlet flange at the bottom of the medicine tank, and both ends of the spray pump are connected to delivery pipes via connectors; the delivery pipes extend outward in a curved shape, and their ends are connected to nozzles; a regulating valve is provided between the spray pump and the connectors to dynamically adjust the output pressure and flow rate of the liquid medicine to match different spraying scenarios.

[0014] The connector serves as a transition interface between the regulating valve and the delivery pipe, ensuring the sealing of the device's piping and allowing for quick assembly and disassembly. The delivery pipe is curved to reduce resistance to the flow of the pesticide solution and prevent pesticide residue from remaining in the pipe. In some embodiments, the nozzle is an adjustable nozzle, connected to the delivery pipe via a threaded connection or a quick-connect fitting, used to adjust the spray angle and spray pattern according to actual needs.

[0015] In some embodiments, the bottom of the spray pump is provided with a fixed rod, and the two ends of the fixed rod are rotatably connected to a rotating rod. The movable end of the rotating rod is provided with a slot, and the delivery pipe passes through the slot and is connected to the nozzle.

[0016] The fixed rod serves as a support structure, with rotating rods connected to both ends. The rotating rods drive the nozzles to adjust their horizontal angle, thus expanding the coverage area.

[0017] In some embodiments, a limiting frame is provided on the outside of the fixed rod, and a limiting groove is opened on the upper part of the limiting frame. The conveying pipe is located above the limiting frame and is inserted into the limiting groove.

[0018] In some embodiments, the angle adjustment mechanism includes a drive element, a notched gear, a spur gear, and an elastic element;

[0019] The drive component is installed on the outward-facing side of the bottom of the fixed rod, and a missing gear is connected to its output shaft;

[0020] A spur gear is connected to the lower end of the shaft at the rotatable connection between the fixed rod and the rotating rod. The spur gear meshes with the missing gear.

[0021] The upper end of the rotating rod's shaft extends through the end of the fixed rod and is connected to an elastic element, which is used to absorb the impact torque on the rotating rod and protect the spur gear and the missing gear.

[0022] The intermittent meshing of the missing gear enables the angle adjustment mechanism to adjust the angle in sections.

[0023] In some embodiments, the elastic element is selected from a combination of torsion springs and disc springs.

[0024] In some embodiments, the micro-pesticide spraying device for pest control further includes a pesticide detection component, which includes a level detector and a detection rod; the level detector is located on the top of the pesticide tank and is used to monitor the pesticide level in the tank in real time; the detection rod is located at the top of the pesticide tank, with its upper end extending out of the tank and connected to the level detector.

[0025] In some embodiments, the drug detection component further includes a control module and an alarm device;

[0026] The control module is installed on the top of the medicine tank and is used to control the spraying pump and regulating valve to switch between single delivery pipe operation mode and dual delivery pipe operation mode, as well as to control the operation of the drive component in the angle adjustment mechanism.

[0027] The alarm device is installed on the top of the medicine tank and connected to the liquid level detector. It is used to transmit alarm signals to the control module and issue an alarm when the liquid level is lower than a preset threshold.

[0028] In some embodiments, the control module integrates a PID algorithm to coordinate the linkage of the spray pump, regulating valve and drive components. If a nozzle on one side is blocked, the control module will automatically close the corresponding regulating valve and switch to single-pipe operation mode. The alarm is connected to the liquid level detector. When the liquid level in the tank is lower than the preset threshold, the alarm will sound an audible and visual alarm to prompt the operator to replenish the agent.

[0029] In some embodiments, the micro-pesticide spraying device for pest control further includes a shock-absorbing pad embedded in the rear of the mounting plate to absorb the vibration energy of the device.

[0030] In some embodiments, the micro-pesticide spraying device for pest control further includes a transparent observation plate embedded in the front of the pesticide tank to support visual inspection of the cleanliness inside the pesticide tank.

[0031] Beneficial effects:

[0032] 1. The micro pesticide spraying device for pest control provided by this utility model adopts a modular design, which allows for precise application of pesticides while quickly changing the type of pesticide solution, cleaning internal residual pesticide solution, and convenient maintenance. The rigid mounting plate design enables the device to be compatible with various automated machines, reducing integration costs. The separate design of the pesticide tank and spraying components is also suitable for the load limitations of micro automated machines.

[0033] 2. The micro pesticide spraying device for pest control provided by this utility model drives the rotating rod to swing through the angle adjustment mechanism, so as to realize the dynamic adjustment of the horizontal spray angle of the nozzle. With the pesticide detection component, the coverage range of the pesticide mist can be flexibly adjusted according to the distribution of pests, so as to make the uniformity of droplet deposition balanced, which is significantly better than the traditional spray bar structure and improves the pesticide utilization rate. The regulating valve and the spraying pump are combined with frequency conversion control, which can match the spraying parameters corresponding to the pest species in real time, and the efficiency is greatly improved compared with manual spraying.

[0034] 3. The micro pesticide spraying device for pest control provided by this utility model monitors the liquid level in the pesticide tank in real time through the linkage of the liquid level detector and the detection rod. With the help of the control module, it realizes automatic alarm for low liquid level, avoids operation interruption, and reduces the frequency of manual inspection. When one side of the nozzle is blocked, the control module closes the corresponding regulating valve and switches to single pipe mode, improving the continuity of operation.

[0035] 4. The micro-pesticide spraying device for pest control provided by this utility model can realize the indexed angle adjustment of the rotating rod through the intermittent meshing of the missing gear and the spur gear, thereby expanding the horizontal spray angle adjustment range and effectively increasing the coverage area compared with the traditional fixed spray bar; the torsion spring at the upper end of the rotating shaft can absorb the instantaneous impact torque, and prevent the missing gear and spur gear from being damaged by external impact when the micro-spray head collides with plants or obstacles, thus extending the service life of the components.

[0045] Example 1:

[0046] like Figures 1 to 3 As shown, this embodiment provides a micro-pesticide spraying device for pest control, including a pesticide tank 1, a mounting plate 2, and a spraying assembly. The mounting plate 2 is wrapped around the rear of the pesticide tank 1. A pesticide outlet is provided at the bottom of the pesticide tank 1, and two threaded pesticide inlets are provided on both sides of the top, each covered with a screw-on pesticide inlet cap. An observation plate 20 is embedded in the front of the pesticide tank 1; in this embodiment, the observation plate 20 is made of transparent acrylic material.

[0047] Mounting plate 2 is a rigid structure used to mount medicine box 1 to the intelligent pest control robot. A shock-absorbing pad 19 is embedded in the rear of the mounting plate; in this embodiment, the shock-absorbing pad 19 is made of silicone.

[0048] The bottom of the medicine tank 1 is connected to the spraying assembly via a flange and bolts, such as... Figure 2 As shown, the spraying assembly includes a spraying pump 3, a regulating valve 4, a connector 5, a delivery hose 6, and a micro nozzle 7. The spraying pump 3 is equipped with regulating valves 4 at both ends via quick-release pipe fittings.

[0049] The output port of the regulating valve 4 is externally connected to a connector 5 via an external thread, and the connector 5 is internally connected to and locked with a delivery hose 6 via an internal thread.

[0050] In this embodiment, the delivery hose 6 is a corrosion-resistant rubber hose, which is curved and extends outward from the medicine tank 1. The end is connected to a micro nozzle 7 via a threaded connection or a quick-connect connector. The micro nozzle 7 is an adjustable nozzle.

[0051] like Figure 4 As shown, the bottom of the spray pump 3 is equipped with a fixed rod 8, which serves as a support structure. The fixed rod 8 is rotatably connected to two ends of a rotating rod 9. The movable end of the rotating rod 9 has a slot, through which the delivery hose 6 passes and connects to the micro-spray head 7.

[0052] A limiting frame 10 is provided on the outside of the fixing rod 8 by a set screw. A limiting groove is opened on the upper part of the limiting frame 10, and the front part of the conveying hose 6 located above the limiting frame 10 is inserted into the limiting groove.

[0053] like Figure 5 As shown, an angle adjustment mechanism is provided at the rotational connection between the fixed rod 8 and the rotating rod 9, including a low-speed motor 15, a missing gear 16, a spur gear 17, and a torsion spring 18. The low-speed motor 15 is bolted to the outward-facing side of the bottom of the fixed rod 8, and the missing gear 16 is connected to its output shaft via a key. The lower end of the rotating shaft at the rotational connection between the fixed rod 8 and the rotating rod 9 is connected to the spur gear 17 via a keyway, and the spur gear 17 and the missing gear 16 are rotatably meshed.

[0054] The upper end of the rotating shaft of the rotating rod 9 passes through the end of the fixed rod 8 and is connected to a torsion spring 18.

[0055] like Figure 2 and Figure 3 As shown, the micro pesticide spraying device for pest control also includes a pesticide detection component, which includes a level detector 11 and a detection rod 12. The level detector 11 is located on the top of the pesticide tank 1 and is used to monitor the pesticide level in the pesticide tank 1 in real time. The detection rod 12 is located at the top of the pesticide tank 1, with its upper end extending out of the pesticide tank 1 and connected to the level detector 11. The level detector 11 is connected to the signal line of the detection rod 12 through a plug-in terminal.

[0056] The pesticide detection component also includes a control module 13 and an alarm 14. The control module 13 is installed on top of the pesticide tank 1 and is used to control the spraying pump 3 and regulating valve 4 to switch between single delivery hose 6 and dual delivery hose 6 operating modes. The alarm 14 is installed on top of the pesticide tank 1 and is wired to the liquid level detector 11. It integrates a PID algorithm to transmit alarm signals to the control module 13 and issue an audible and visual alarm when the liquid level is lower than a preset threshold. The control module 13 communicates with the main control system of the intelligent pest control robot via a bus interface, and the alarm 14 is connected to the current output terminal of the control module 13 via a wire.

[0057] Example 2:

[0058] This embodiment, based on Embodiment 1, provides a method for using a micro-pesticide spraying device for pest control, including:

[0059] Before use, install this device onto the intelligent pest control robot: fix the medicine tank 1 to the back support platform of the intelligent pest control robot with bolts, ensure that the mounting plate 2 is completely in contact with the contact surface of the intelligent pest control robot body, and use a level to calibrate the verticality of the medicine tank 1 to prevent uneven distribution of the medicine liquid;

[0060] The fixing rod 8 is connected to the front end of the robot chassis via a flange, and additional anti-loosening gaskets are used to prevent loosening caused by operational vibration; the control module 13 communicates with the main control system of the intelligent pest control robot via a bus, and the signal line of the liquid level detector 11 is connected to the signal channel of the control module 13;

[0061] Perform zero-point calibration and full-scale calibration of the liquid in the medicine tank;

[0062] Connect the drive line of the low-speed motor 15 to the DC output terminal of the power distribution box of the intelligent prevention and control robot, and configure the pulse width modulation duty cycle in the control module 13.

[0063] Insert the rotating rod 9 into the bearing seat of the fixed rod 8; install the angle adjustment mechanism; connect the micro nozzle 7 to the delivery hose 6 via a quick-connect fitting; match the limiting groove of the limiting bracket 10 with the outer diameter of the delivery hose 6; use nylon cable ties to help fix the bent section of the delivery hose 6 to prevent flow loss due to bending; the installation is now complete.

[0064] When in use, the control module 13 first performs a self-test, checking the connection status of the spray pump 3, liquid level detector 11, alarm 14, and low-speed motor 15. The liquid level detector 11 monitors the liquid level in the medicine tank 1 in real time through the detection rod 12 and feeds the data back to the control module 13. If the liquid level is lower than the preset threshold, the alarm 14 will issue an audible and visual alarm to prompt the operator to replenish the medicine.

[0065] The intelligent pest control robot scans the field environment using its onboard visual sensors to identify pest types and distribution density. The control module 13 automatically matches the amount of pesticide to be sprayed based on a preset database and dynamically adjusts the output pressure through the regulating valve 4.

[0066] The angle adjustment mechanism is activated, and the low-speed motor 15 drives the misaligned gear 16 to mesh with the spur gear 17, which in turn drives the rotating rod 9 to swing within a suitable range. The micro nozzle 7 adjusts the horizontal spray angle synchronously with the rotating rod 9 to ensure that the spray mist covers the target area. The spray pump 3 operates in frequency conversion mode, and the liquid medicine is diverted to two delivery hoses 6 through the regulating valve 4, and finally forms uniform droplets through the micro nozzle 7.

[0067] The front end of the delivery hose 6 is inserted into the limiting groove of the limiting frame 10. When the robot turns or encounters plant obstacles, the rotating rod 9 buffers the mechanical impact through the torsion spring 18 to avoid collision damage to the micro nozzle 7.

[0068] The liquid detection component continuously monitors the flow rate. If a micro nozzle 7 on one side becomes clogged, the control module 13 will automatically close the corresponding regulating valve 4 and switch to single-pipe operation mode.

[0069] After the preset working area is completed, the control module 13 shuts off the spray pump 3, and the low-speed motor 15 resets the rotating rod 9 to its initial position.
