Description

Technical Field

[0001] This invention relates to the agricultural field, and more specifically to an intelligent agricultural drone and an intelligent working method for the agricultural drone. Background Technology

[0002] In recent years, the country has increased investment in scientific research in various fields, which has accelerated the research and development of agricultural equipment. In the context of large-scale and automated centralized planting, technological products are gradually replacing some traditional manual farming methods. For example, CN205770168U, this utility model relates to an agricultural drone, belonging to the field of drone technology. It includes a frame, rotors, lateral linkages, rotor drive devices, and support legs. At least four rotors are installed around the frame via lateral linkages. Each rotor is connected to a rotor drive device. The support legs are located below the frame. The frame is equipped with a wind speed measuring device and a control device. A telescopic device is located below the frame. A liquid storage tank is located below the telescopic device. Multiple liquid outlets are located below the liquid storage tank. The control device controls the operation of the telescopic device and also controls the opening and closing of each liquid outlet. This agricultural drone adjusts the spraying height according to the wind speed to spray an appropriate amount of pesticide, resulting in uniform pesticide coverage and high spraying quality. This invention lacks a design for sowing agricultural seeds and is only suitable for pesticide spraying, resulting in a limited scope of application. Furthermore, the absence of a tracked drive design necessitates manual movement on the ground. Given the increasing size of agricultural drones, manual movement is extremely inconvenient and increases the likelihood of damage to the drone's internal precision instruments. The lack of an infrared alarm design means that if someone is below the drone, it cannot avoid being sprayed with pesticides, posing a significant threat to personal safety. For example, CN216070527U discloses a thermal imaging wind-controlled agricultural drone, comprising an agricultural drone equipped with a spray tank for irrigation and an anemometer for detecting wind speed and direction. The spray tank is also equipped with a thermal imager, whose outer wall has two interlocking protective shells. This thermal imaging-based wind-controlled agricultural drone uses an anemometer to adjust its forward angle and speed in real time according to changes in wind speed and direction, ensuring uneven pesticide spraying. The thermal imager also enables nighttime operation and real-time monitoring and recording of crop conditions, facilitating assessment of pest infestations and irrigation needs. Furthermore, the device's drive mechanism allows for flexible opening and closing of two protective shells, effectively protecting the thermal imager from damage in harsh environments. However, this invention lacks storage design for agricultural use, hindering convenient operation for farmers. The absence of an infrared alarm means it cannot avoid spraying pesticides onto people underneath, posing a significant threat to their safety. Summary of the Invention

[0003] The purpose of this invention is to provide an intelligent agricultural drone and an intelligent operating method for the agricultural drone. The movement of the entire device is achieved by a tracked drive and a propeller drive, enabling both land and air operations.

The pesticide spraying device sprays pesticides and waters crops to increase soil moisture and improve work efficiency. The tracked drive and seed sowing device enable automatic seed sowing and humidification on the ground, maintaining a certain seed sowing density and improving seed sowing efficiency and survival rate. An agricultural storage device stores small and medium-sized agricultural tools or pesticides, enhancing the drone's practicality for agricultural operations. Given the current trend towards larger agricultural drones, manual movement is extremely inconvenient and prone to damage.

[0035] Specific implementation

[0036] The present invention will now be described in further detail with reference to the accompanying drawings. Specific Implementation Example 1:

[0038] The following is combined Figure 1-14 This embodiment describes an intelligent agricultural drone and its intelligent operating method, comprising an agricultural storage device 1, a pesticide spraying device 2, an agricultural seed sowing device 3, a track drive device 4, an infrared alarm device 5, a propeller drive device 6, and a frame 7. The agricultural storage device 1, pesticide spraying device 2, agricultural seed sowing device 3, track drive device 4, infrared alarm device 5, and propeller drive device 6 are all connected to the frame 7. The agricultural storage device 1 is connected to the pesticide spraying device 2 and the agricultural seed sowing device 3, and the agricultural seed sowing device 3 is connected to the track drive device 4. Specific Implementation Example 2:

[0040] The following is combined Figure 1-14 This embodiment further explains Example 1. The agricultural storage device 1 operates as follows: Motor A101 reverses direction, driving spur gear A102 via its output shaft. Spur gear A102 drives spur gear B103, which in turn drives spur gear C104. Spur gear C104 drives belt A105, which in turn drives thick spur gear A106. Thick spur gear A106 then moves rack A107 in the x-direction, which in turn moves the storage box cover 108 in the x-direction, opening the agricultural storage device 1. At this point, the storage box can be placed inside. For small agricultural tools or pesticides, the motor A101 is started and rotates forward. The motor A101 drives the spur gear A102 to rotate through its output shaft. The spur gear A102 drives the spur gear B103 to rotate. The spur gear B103 drives the spur gear C104 to rotate. The spur gear C104 drives the belt A105 to rotate. The belt A105 drives the thick spur gear A106 to rotate. The thick spur gear A106 drives the rack A107 to move in the x-direction. The rack A107 drives the storage box cover 108 to move in the x-direction, and the agricultural storage device 1 closes. The opening and closing distance and speed of the agricultural storage device 1 can be adjusted by changing the motor output time and the ratio of the number of teeth of the gear and rack. Specific Implementation Example 3:

[0042] The following is combined Figure 1-14 This embodiment further explains Example 1. The pesticide spraying device 2 operates as follows: Motor B201 is started, and its output shaft drives helical gear A202 to rotate. Helical gear A202 drives helical gear B203 to rotate, and helical gear B203 drives helical gear column A205 to rotate. Helical gear column A205 drives the sealing plate 206 to move up and down within the pesticide tank 208. The hole in the pesticide tank cover 207 and the inner wall of the pesticide tank 208 provide guidance for the sealing plate 206. The pesticide inlet pipe 209 contains... One-way valves allow only inflow and no outflow. Pesticide or water enters the pesticide tank 208 through the pesticide inlet pipe 209. The sealing plate 206 presses the pesticide or water downwards, causing it to spray out from the spray nozzles A210 and B211. Both spray nozzles A210 and B211 have one-way valves, allowing only outflow and no inflow. When water is added through the pesticide inlet pipe 209, the sealing plate 206 moves upwards, creating air pressure to draw in water and pesticide, assisting in the addition of water and pesticides. The spray volume and speed are adjusted by changing the ratio of the helical gear teeth and the motor output time. Specific Implementation Example 4:

[0044] The following is combined Figure 1-14This embodiment further explains Example 1. The operation of the agricultural product seed sowing device 3 is as follows: Motor C301 is started, and motor C301 drives spur gear D302 to rotate via its output shaft. Spur gear D302 drives spur gear E303 to rotate, spur gear E303 drives spur gear F304 to rotate via connecting rod D314, spur gear F304 drives spur gear G305 to rotate, and spur gear G305 drives seed separation disc 306 to rotate. The seeds are separated one by one in the seed output guide rail 307 through grooves on the seed separation disc 306, achieving one-by-one sowing. The sowing spacing of the separated seeds is adjusted by changing the number of grooves on the seed separation disc 306 and the speed of the conveyor belt. The size of the grooves is changed according to the seed size to adjust the sowing of different types and sizes of seeds. Motor D310 is started rotating forward, and motor D310 drives connecting rod A311 via its output shaft. When the device rotates, connecting rod A311 drives connecting rod B312 to rotate, and connecting rod B312 drives connecting column C313 to rotate. At this time, connecting column C313 moves in the slide groove of the bottom gear motor support 702, causing spur gear G305 to disengage from spur gear F304, enabling the device to move on the ground without sowing. When the device starts in reverse, motor D310 drives connecting rod A311 to rotate through its output shaft. Connecting rod A311 drives connecting rod B312 to rotate, and connecting rod B312 drives connecting column C313 to rotate. At this time, connecting column C313 moves in the slide groove of the bottom gear motor support 702, causing spur gear G305 to re-engage with spur gear F304. Seed sowing can then be performed. The sowing spacing can be adjusted by changing the gear ratio and the operating speed of motor C301. The operating mode of the device can be adjusted by running motor D310 in both forward and reverse directions, i.e., seed sowing mode and device moving without sowing mode. Specific Implementation Example 5:

[0046] The following is combined Figure 1-14This embodiment further explains Example 1. The track drive device 4 operates as follows: spur gear F304 drives spur gear H401 to rotate; spur gear H401 drives spur gears I402 and K413 to rotate via connecting column E410; spur gear I402 drives belt B403 to rotate; belt B403 drives spur gear J404 to rotate; spur gear J404 drives sprocket A406 to rotate via connecting column F405; sprocket A406 drives track A407 to rotate. A407 drives sprockets B408 and C409 to rotate, spur gear K413 drives belt C414 to rotate, belt C414 drives spur gear L415 to rotate, spur gear L415 drives sprocket D417 to rotate via connecting column I416, sprocket D417 drives track B418 to rotate, track B418 drives sprockets E419 and F420 to rotate, thereby realizing the linear movement of the equipment on the ground and driving the equipment to perform linear seed sowing. The track running speed can be adjusted by changing the gear ratio. Specific Implementation Example Six:

[0048] The following is combined Figure 1-14 This embodiment further explains Example 1. The infrared alarm device 5 operates as follows: During the drone's aerial operation, the infrared sensor 501 scans a certain range around the drone. When someone appears, the infrared sensor 501 sends an electrical signal to the loudspeaker 502, causing the loudspeaker 502 to sound an alarm to drive away the person. At the same time, the electrical signal is also sent to motors B201 and E601. Motor B201 stops the spraying operation, and motor E601 keeps the equipment hovering in the air. Specific Implementation Example 7:

[0050] The following is combined Figure 1-14 This embodiment further explains Example 1. The propeller transmission device 6 operates by starting the motor E601, which drives the propeller A602 to rotate through its output shaft. The propeller A602 generates sufficient lift, which drives the housing support 701 into the air through the motor support sleeve A603 and the propeller support rod A604, thereby lifting the equipment into the air. The overall direction and speed of the equipment can be adjusted by changing the speed of the four propeller motors. Specific Implementation Example 8:

[0052] The following is combined Figure 1-14 This embodiment further explains Example 1. The frame 7 mainly consists of a bottom gear motor support 702 and a track support 703, both of which are fixedly connected to the housing support 701. These components provide support for various parts of the equipment. Under conditions of uneven terrain and unstable airflow, the frame provides overall support for the equipment, preventing damage and extending its service life.
