Description

Technical Field

[0001] This utility model relates to the field of Sichuan pepper planting technology, specifically to a microbial agent spraying device for biological control of diseases and pests of Sichuan pepper trees. Background Technology

[0002] In the cultivation of Sichuan pepper trees, pest and disease control is a crucial aspect of ensuring yield and quality. Biological control, due to its environmentally friendly and sustainable characteristics, is widely used for pest and disease control in Sichuan pepper trees, with spraying liquid microbial agents being a common method. A variety of suitable liquid microbial agents are available, including Bacillus thuringiensis agents (such as Bacillus thuringiensis), fungal agents (such as Beauveria bassiana and Metarhizium anisopliae), and actinomycete agents (such as Streptomyces), which can control common pests and diseases of Sichuan pepper trees such as aphids, spider mites, Sichuan pepper swallowtail butterflies, anthracnose, and root rot.

[0003] Currently, the application of fungicides to Sichuan pepper trees is mostly done using agricultural drones, which offer advantages such as high operational efficiency, adaptability to complex terrain, and reduced labor costs. However, these liquid fungicides (especially those containing solid active ingredients) have a tendency to settle during application: traditional agricultural drone tanks are mostly static storage structures, and prolonged static placement of the fungicide causes the active ingredients to settle, resulting in uneven concentrations of the fungicide in the upper and lower layers of the tank. When spraying, the initial concentration of the fungicide is too low to achieve the desired control effect; the later concentration is too high, which may not only cause phytotoxicity to the Sichuan pepper trees but also lead to waste of the fungicide.

[0004] Some existing technologies attempt to add a stirring device inside the spray tank, but most are single rotary stirrs, which can only stir a local area of ​​the tank and cannot cover the upper and lower layers. The sedimentation problem has not been effectively solved, thus affecting the stability and accuracy of pest and disease control. Therefore, there is an urgent need for a spraying device that can fully stir the fungicides in the tank and prevent sedimentation, in order to meet the needs of biological control of pests and diseases of Sichuan pepper trees. Utility Model Content

[0005] The purpose of this invention is to provide a microbial agent spraying device for the biological control of pests and diseases of Sichuan pepper trees, which solves the problem mentioned in the background art that the microbial agent in the medicine tank of existing plant protection drones tends to sink to the bottom, resulting in inconsistent concentrations.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a biological control agent spraying device for pests and diseases of Sichuan pepper trees, comprising a plant protection drone and a stirring mechanism mounted on the drone's medicine tank. The medicine tank consists of a tank body and a lid detachably connected to the tank body. The stirring mechanism includes a motor and a spiral lifting and rotating assembly mounted on the upper and lower sides of the lid, and a stirring assembly mounted on the spiral lifting and rotating assembly and located inside the tank body. The motor is driven by the spiral lifting and rotating assembly to drive the stirring assembly to rotate and move vertically back and forth.

[0007] Furthermore, the spiral lifting and rotating assembly includes a guide sleeve located in the middle of the bottom side of the cover, a splined rod connected to the motor output shaft and located inside the housing, and a movable sleeve sleeved on the splined rod and vertically slidingly engaged with the splined rod; a guide groove is provided on the inner wall of the guide sleeve, the guide groove is a spatial spiral elliptical groove and is coiled on the inner wall of the guide sleeve, and a guide rod is provided on the outer wall of the movable sleeve, the guide rod is located in the guide groove and slidesly engaged with the guide groove.

[0008] Furthermore, the stirring assembly includes a rotating shaft connected to the bottom of the movable sleeve and stirring blades disposed at the bottom of the rotating shaft.

[0009] Furthermore, the box cover is provided with a liquid inlet pipe, and the liquid inlet pipe is provided with a valve.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. The stirring mechanism of this utility model achieves stirring through a compound motion of rotation and vertical reciprocating movement. A motor drives a splined rod to rotate, causing the moving sleeve and stirring blades to rotate synchronously. Simultaneously, a guide rod on the moving sleeve slides along an annular elliptical guide groove on the inner wall of the guide sleeve, forcing the stirring blades to move up and down reciprocally during rotation. This compound motion can cover different heights and areas within the tank, effectively breaking the tendency for bacterial agent sedimentation and ensuring a consistently uniform concentration of bacterial agent within the tank, thus avoiding fluctuations in concentration that could affect the control effect.

[0012] 2. The stirring mechanism of this utility model is integrated on the medicine tank cover. It adopts a sliding fit between the spline rod and the moving sleeve, and a mechanical linkage structure between the guide rod and the guide groove. It does not require additional complex drive components. The overall size is small and the weight is light. It will not significantly increase the load of the agricultural drone, and ensure the flight stability and endurance of the drone.

[0013] 3. The medicine box of this utility model adopts a design in which the box body and the box cover are detachably connected, which facilitates the cleaning and maintenance of the box body and the stirring components in the later stage; the connection between the liquid inlet pipe, the liquid pump and the nozzle is also detachable, which facilitates the addition of fungicide, pipeline replacement and equipment maintenance; the motor, valve and other components are all powered by the plant protection drone's own power supply, which eliminates the need for an additional power source and simplifies the equipment layout.

[0014] 4. Combining the efficient spraying capabilities of plant protection drones, this invention can complete the spraying of microbial agents while mixing, avoiding operation interruptions caused by stopping the mixing process; the uniform concentration of microbial agents can ensure that each pepper tree receives a consistent dose of microbial agents, improving the accuracy of pest and disease control and reducing waste of microbial agents and environmental pollution.

[0015] In summary, this utility model effectively solves the problem of bacterial agent sedimentation in traditional spraying devices through innovative mixing mechanism design, taking into account work efficiency, prevention and control effect and equipment adaptability. It is especially suitable for biological control of crop diseases and pests such as pepper trees that require precise spraying of bacterial agents. Attached Figure Description

[0025] Please see Figures 1 to 7This utility model discloses a biological control device for pests and diseases of Sichuan pepper trees, mainly composed of a plant protection drone 1 and a stirring mechanism mounted on the tank 2 of the plant protection drone 1. The tank 2 includes a body 3 located on the frame of the plant protection drone 1 and a cover 4 detachably connected to the body 3 by bolts or threads. An inlet pipe 13 is provided on the cover 4, and a valve 14, specifically a solenoid valve, is also provided on the inlet pipe 13, powered by the plant protection drone 1's own power supply. The plant protection drone 1 also includes a liquid pump 15 and a nozzle 16, both located on the frame of the plant protection drone 1. The inlet of the liquid pump 15 is detachably connected to an outlet pipe at the bottom of the body 3 via a pipeline, and the outlet is detachably connected to the nozzle 16 via a pipeline (specifically, a quick-release connector, flange, etc., ensuring a tight seal after installation). The stirring mechanism stirs the liquid fungicide in the tank 2 to prevent the fungicide from settling to the bottom, resulting in uneven concentration and affecting the control effect.

[0026] Specifically,

[0027] The stirring mechanism includes a motor 5, a spiral lifting and rotating assembly, and a stirring component. The motor 5 is specifically a stepper motor, also powered by the power supply of the agricultural drone 1, and is fixedly installed in the upper center of the cover 4, with its output shaft passing through the cover 4 and located inside the housing 3. The spiral lifting and rotating assembly consists of a guide sleeve 6 fixed in the lower center of the cover 4, a splined rod 7 connected to the output shaft of the motor 5 and located inside the housing 3, and a movable sleeve 8 sleeved on the outer wall of the splined rod 7 and vertically sliding with it. A guide groove 9 is formed on the inner wall of the guide sleeve 6; this guide groove 9 is a spatial spiral elliptical groove coiled on the inner wall of the guide sleeve 6, such as... Figure 7 As shown; a guide rod 10 is provided on the outer wall of the movable sleeve 8, and the guide rod 10 is located in the guide groove 9 and slides in the guide groove 9; when the motor 5 drives the spline rod 7 to rotate, the movable sleeve 8 rotates synchronously, driving the guide rod 10 to slide in the guide groove 9. Since the guide groove 9 covers both ends of the guide sleeve 6, it drives the movable sleeve 8 to move vertically back and forth while rotating. The stirring assembly consists of a rotating shaft 11 connected to the bottom of the movable sleeve 8 and stirring blades 12 provided at the bottom of the rotating shaft 11; when the movable sleeve 8 rotates and moves vertically back and forth, it drives the stirring blades 12 to move synchronously with it, so as to stir the bacterial agent in the medicine tank 2.

[0028] Working principle and process of this utility model:

[0029] I. Working Principle

[0030] This invention uses a motor 5 to drive a spiral lifting and rotating component, which in turn drives a stirring component to achieve a combined motion of rotation and vertical reciprocating movement. This fully stirs the liquid bacterial agent in the medicine tank 2, preventing sedimentation and uneven concentration, thus ensuring the stability of the spraying effect. The specific principle is as follows:

[0031] The motor 5 is powered by the built-in power supply of the agricultural drone 1, and its output shaft drives the spline rod 7 to rotate. Since the movable sleeve 8 and the spline rod 7 are vertically slidingly fitted (a vertical groove adapted to the spline rod is provided on the movable sleeve 8, and the vertical sliding fit between the movable sleeve and the spline rod is achieved through the groove), when the spline rod 7 rotates, it will synchronously drive the movable sleeve 8 to rotate, thereby causing the rotating shaft 11 and the stirring blade 12 connected to the bottom of the movable sleeve 8 to rotate synchronously.

[0032] The inner wall of the guide sleeve 6 is provided with an annular elliptical guide groove 9, and the guide rod 10 on the outer wall of the movable sleeve 8 is embedded in the guide groove 9 and slides with it. When the movable sleeve 8 rotates with the spline rod 7, the guide rod 10 slides along the annular elliptical guide groove 9. Since the guide groove 9 is distributed at both ends of the guide sleeve 6, it forces the movable sleeve 8 to move vertically back and forth (up or down) along the spline rod 7 while rotating.

[0033] The stirring blades 12 rotate and move vertically back and forth synchronously with the moving sleeve 8, which can cover the bacterial agent at different heights and in different areas within the medicine tank 2, breaking the static sedimentation trend and ensuring uniform bacterial agent concentration.

[0034] II. Work Process

[0035] Open the lid 4 or inject liquid bacterial agent into the body 3 of the medicine tank 2 through the liquid inlet pipe 13 on the lid 4 (controlled by a valve), and close the valve 14. Ensure that all components are installed in place, and connect the motor 5, the liquid pump 15, etc. to the power supply of the plant protection drone 1.

[0036] The plant protection drone 1 takes off and flies to the pepper forest along a preset path. During the operation, the motor 5 starts and drives the spline rod 7 to rotate. Through the above principle, the stirring blade 12 is driven to rotate and move vertically back and forth, continuously stirring the fungicide in the box 3.

[0037] When the liquid pump 15 is started, its inlet is connected to the bottom of the box 3 through a pipeline, and the well-stirred bacterial agent is extracted and transported to the nozzle 16 through the outlet pipeline. The nozzle 16 then sprays the bacterial agent evenly onto the branches and leaves of the pepper tree to achieve biological control of pests and diseases.

[0038] After spraying is completed, the motor 5 and the liquid pump 15 stop working, the plant protection drone 1 returns to its home base, the pipe connected to the liquid outlet can be removed, the remaining fungicide can be drained through the liquid outlet, and the box cover 4 can be removed to clean the box body 3.

[0039] Through the above process, this device can achieve efficient spraying using plant protection drones 1, and avoid bacterial agent precipitation through compound stirring motion, solving the problem of uneven concentration affecting the control effect in traditional spraying. It is especially suitable for crop scenarios such as pepper trees that require precise spraying.
