[0029] like Figures 1-2 As shown, this utility model provides an automatic loading device for unmanned aerial vehicles (UAVs), comprising:
[0030] Multi-hopper module 1 is used to store and discharge granular materials, such as seeds or feed.
[0031] In this embodiment, three hoppers are configured: a large particle hopper 101, a medium particle hopper 102, and a small particle hopper 103, corresponding to the storage of materials of different particle sizes. Each hopper is equipped with an ultrasonic level sensor, which sends an alert to the control module 6 when the material level falls below a preset design threshold. The upper part of the hopper is cylindrical, and the lower part is funnel-shaped. A vibration device 104 is installed on the inner wall of the hopper's discharge pipe. The weighing and conveying module 2 is located directly below the end of the discharge pipe. The multi-hopper module 1 sequentially discharges materials from the corresponding hoppers to the weighing and conveying module 2 according to the instructions of the control module 6.
[0032] The weighing and conveying module 2 weighs and conveys materials, including a weighing device 202, a conveyor belt device 201, a transfer bin 203, a conveying pipeline 205, and a Roots blower 204. In this embodiment, the weighing device 202 in the weighing and conveying module 2 weighs the materials flowing out of the multi-bin module 1 in real time. When the material weight reaches a preset weight value, a feedback signal is sent to the control module 6, which then sends a command to the multi-bin module 1 to stop discharging. Subsequently, driven by the conveyor belt device 201, the material enters the transfer bin 203. Under the action of the wind force of the Roots blower 204, the material flows stably in the conveying pipeline 205. The conveying pipeline 205 extends diagonally downward from indoors through the wall to an underground location outdoors. The end 206 of the conveying pipeline is connected to the drone hopper opening 408 of the drone module 4 via an air gap. A pressure sensor is installed inside the conveying pipeline 205 to monitor the internal pressure of the pipeline in real time and realize real-time early warning of pipeline blockage faults.
[0033] The medicine storage module 3 includes a medicine storage bin 302 and a spray nozzle device 304, which are connected to the weighing and conveying module 2. It is used to store liquid or powdered medicines, and the medicines can be mixed evenly with the materials in real time during the material flow process. In this embodiment, the medicine storage bin 302 has a built-in stirring device 301 and an ultrasonic level sensor. The medicine storage bin 302 is connected to the weighing and conveying module 2 through a connecting pipe 303. The spray nozzle device 304 is installed at the end of the connecting pipe 303, which can evenly spray the medicines into the materials inside the conveying pipe 205.
[0034] The UAV module 4 includes a flight control module 401, a rotor module 402, an infrared positioning module 403, a battery compartment 404, a UAV hopper 406, and a UAV support device 407. A spraying module 405 is installed at the bottom of the hopper. The hopper 406 has a narrow top and bottom and a wider middle design, with an opening 408 on one side at the top. During UAV landing, the opening 408 precisely aligns with the end 206 of the conveying pipe of the weighing and conveying module 2. The UAV support device 407 consists of four symmetrically distributed support rods, which, in conjunction with the four infrared positioning frames of the UAV takeoff and landing platform 501, achieve precise alignment and landing.
[0035] The UAV lifting platform module 5 includes a base 505, a lifting device 502, and a UAV takeoff and landing platform 501. The lifting device base has a built-in motor 504, connected to a multi-layered folding metal frame via a metal tube 503. The motor 504 rotates forward and backward to adjust the lifting of the UAV takeoff and landing platform 501. The lifting device 502 is equipped with a highest point limit structure and a lowest point limit structure to limit the platform's lifting stroke and ensure operational safety. In this embodiment, four infrared positioning frames 5001 are configured on the surface of the UAV takeoff and landing platform 501 to cooperate with the UAV infrared positioning module 403 for precise positioning. When the distance between the center of the UAV support rod and the center of the infrared positioning frame is no greater than 5cm, the UAV is considered to have landed precisely.
[0036] The overall equipment of this utility model is divided into indoor and outdoor areas. The multi-material silo module 1, weighing and conveying module 2, medicine silo module 3, and control module 6 are arranged indoors, which can effectively protect the equipment and reduce environmental interference. The drone module 4 and drone lifting platform module 5 are arranged outdoors, and the drone lifting platform module 5 is embedded in the outdoor underground position, saving space and adapting to outdoor operation scenarios.
[0037] Control module 6 is the core control unit of this device, electrically connected to each functional module. It can receive interactive data from the cloud information module and simultaneously collect monitoring signals from various sensors to achieve fully automated control of the entire process, including material discharge control, weighing control, reagent mixing, fan speed regulation, platform lifting, and fault early warning. The ultrasonic level sensors in multi-silo module 1 and reagent silo module 3 can monitor the remaining material and reagent levels in real time. When the remaining level falls below a preset threshold, an early warning message is sent to management personnel via control module 6 and the cloud information module.
[0038] The operating frequency of the Roots blower 204 can be manually pre-calibrated to determine the optimal operating frequency, so that after the material is sprayed out from the end of the conveying pipe 206, it falls stably into the open 408 of the drone hopper with a standard parabolic trajectory, ensuring that there is no spillage or deviation during the loading process.
[0039] The cloud-based information module can collect external meteorological data in real time and issue loading operation instructions to the control module 6 only when there is no rain or snow and the ambient wind force is below the safe flight threshold of the drone. If continuous rain, snow, strong winds or other unsuitable weather conditions are detected, feedback information will be sent to the management personnel in a timely manner to avoid flight operation risks.
[0040] In this embodiment, the workflow of a complete unmanned aerial vehicle (UAV) automated loading device includes:
[0041] S1, the control module 6 receives the drone loading instruction data sent by the cloud information module, including the drone number, the corresponding working hopper number, and the target loading weight information; when the drone module 4 has landed on the drone take-off and landing platform 501, it directly proceeds to the next step; if the drone is not in position, it waits for the drone to complete the current task and then return to land.
[0042] S2. After returning from the drone module 4, the drone autonomously lands on the drone lift platform module 5. It completes precise alignment through infrared positioning and proceeds to the next step after landing precisely. If the alignment deviation exceeds the standard during the first landing, the drone will take off autonomously, make minor adjustments to its altitude, and land again until it is precisely in place.
[0043] S3. When the UAV lifting platform module 5 descends to the lowest limit position, the control module 6 issues a material feeding command to the multi-bin module 1 based on the received material loading information.
[0044] S4. The multi-bin module 1 starts discharging material from the corresponding numbered bin according to the instruction. By adjusting the working frequency of the vibration device 104 on the inner wall of the discharge pipe, the material is conveyed to the weighing and conveying module 2 at a discharge speed that is fast at first and then slows down, ensuring efficient and accurate discharge. During the process, the ultrasonic level sensor monitors the remaining material in the bin in real time to realize the remaining material warning.
[0045] S5. Weighing device 202 weighs the outflowing material in real time throughout the process. When the material weight reaches the preset target weight, it immediately sends a signal to control module 6, and control module 6 controls multi-bin module 1 to stop discharging.
[0046] S6. Conveyor belt device 201 starts, transporting a fixed amount of material to transfer bin 203. Roots blower 204 operates at a preset optimal frequency, driving the material to flow stably within conveying pipe 205. Simultaneously, medicine bin module 3 receives control commands and starts operating. The medicine in storage bin 302 is evenly sprayed into the conveying pipe 205 through connecting pipe 303 and nozzle device 304, thoroughly mixing with the flowing material. During the process, ultrasonic level sensor in medicine bin monitors the remaining medicine level in real time, providing an early warning of remaining levels. Pressure sensor in conveying pipe monitors the pipe condition in real time, providing an early warning of blockages.
[0047] S7. The mixed material is sprayed out from the end of the conveying pipe 206 and falls smoothly into the opening 408 of the drone hopper 406 along a preset parabolic trajectory. After the material is completely conveyed, the Roots blower 204 and the medicine hopper module 3 stop working simultaneously.
[0048] S8. After the drone is loaded with materials, the drone lifting platform module 5 rises to the highest limit position, and the drone flight control module 401 completes the self-test of the whole system. After the self-test is qualified, the drone takes off to carry out the material feeding operation. After the drone completes the operation, it automatically returns to the drone take-off and landing platform 501, and the platform falls back to the lowest limit position, completing one operation cycle.
[0049] S9. If the UAV system fails the self-test, the fault signal is fed back to the control module 6. The control module 6 determines whether manual intervention is required for troubleshooting. At the same time, the fault information is pushed to the management personnel through the cloud information module. After the fault is manually checked and repaired, the UAV can take off and operate normally.
[0050] At the same time, the medicine storage module 3 will receive the instruction from the control module 6 and start working synchronously. The medicine is sprayed through the nozzle 304 and mixed evenly with the material transported in the conveying pipe 205, and flows in the conveying pipe 205, and enters step S7.
