Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a spraying unmanned aerial vehicle for forestry. Background Art

[0002] A vertical take-off fixed-wing spraying drone is a drone that combines vertical take-off and landing (VTOL) and fixed-wing aircraft technology. This technology allows the aircraft to take off and land vertically without a runway. Common VTOL technologies include tilt-rotor, rotorcraft and vector thrust jet engines. Fixed-wing aircraft usually have higher cruising efficiency and flight speed, so they are more suitable for long-distance missions. Its design takes into account factors such as flight stability, aerodynamic performance and payload capacity.

[0003] However, after the existing vertical take-off fixed-wing spraying drones complete the spraying task, a large amount of spray chemicals usually remain in the medicine barrel inside the drone, which is not only inconvenient to clean, but also brings inconvenience or even danger to the next use. Due to the viscosity or chemical properties of the agent, the residue is often difficult to clean thoroughly. The internal structure of the spraying drone is complex, with many nooks and crannies, which makes it even more difficult to thoroughly clean the residue. Utility Model Content

When the drone body 1 flies to a suitable position, the pump 201 can be started through the power supply system of the pump 201, so that when the pump 201 is running, the medicine in the medicine barrel 102 is drawn into the pump 201 through the first medicine outlet pipe 2, and then the pump 201 transports the medicine so that the medicine flows into the water pipe joint 203 through the second medicine outlet pipe 202, and then the water pipe joint 203 disperses the medicine so that the medicine enters the second nozzle 205 through the medicine outlet rod 204 on the support column 206, and then the second nozzle 205 sprays the medicine to spray the forestry with medicine. By setting the pump 201 and the second nozzle 205, it can be ensured that the medicine is evenly sprayed on the target area, thereby improving the coverage and effect of the spraying.

[0029] Working principle: During use, when the medicine barrel 102 is used up and there is a large amount of medicine remaining inside, the external pipe can be connected to the rotary joint 115, and then clean water can be introduced through the external pipe, so that the clean water enters the interior of the drainage groove 104 through the rotary joint 115, and then the drainage groove 104 transports the clean water into the interior of the first nozzle 108, so that the first nozzle 108 sprays clean water to clean the inner wall of the medicine barrel 102, and then the motor 106 is started through the power supply system of the motor 106 (it should be noted that the model of the motor 106 is Y80M1-4, and the power is 0.55KW), so that the motor 106 is transmitted to the first bevel gear 105 through the second bevel gear 107 when running, and the first bevel gear 105 is rotated by the rotating rod 103 to drive the first nozzle 108 into The rotating rod 103 rotates synchronously to flush the inner wall of the medicine barrel 102 in all directions, and when the rotating rod 103 rotates, it drives the second connecting column 109 to rotate synchronously, so that the second connecting column 109 drives the scraper 110 to rotate in a circle through the slide groove 111, and the residual medicine on the inner wall of the medicine barrel 102 is scraped off. When the cleaning is completed, the one-way valve 114 can be opened to allow the sewage to flow out of the interior of the medicine barrel 102 through the sewage pipe 113, and the linkage structure such as the motor 106 and the first nozzle 108 can be used to realize the comprehensive flushing and scraping of the interior of the medicine barrel 102 when the device is in use, effectively remove the residual medicine and dirt, ensure thorough cleaning, and realize the automation of the cleaning process, reduce manual intervention and labor costs, and improve cleaning efficiency and consistency. When in use, the medicine can be first injected into the medicine barrel 102 through the medicine inlet pipe 112, and then the drone body 1 can be started through the driving system of the drone body 1, so that the drone body 1 can drive the medicine barrel 102 to fly synchronously through the first connecting column 101 during operation. After the drone body 1 flies to a suitable position, the pump 201 can be started through the power supply system of the pump 201 (it should be noted that the model of the pump 201 is HG-090-C, and the power is 90W), so that when the pump 201 is running, the medicine in the medicine barrel 102 is drawn into the pump 2 through the first medicine outlet pipe 2 01, and then transported by pump 201, so that the medicine flows into water pipe joint 203 through second medicine outlet pipe 202, and then dispersedly transported by water pipe joint 203, so that the medicine enters the interior of second nozzle 205 through medicine outlet rod 204 on support column 206, and then the second nozzle 205 sprays the medicine to spray the forestry. Through the setting of pump 201 and second nozzle 205, it can be ensured that the medicine is evenly sprayed on the target area. The flow meter in nozzle 205 can control the spraying flow of the medicine, so as to quantitatively control the spraying amount of the medicine, thereby improving the coverage and effect of the spraying.
