Description

Technical Field

[0001] This utility model relates to the field of drones, specifically an agricultural drone with automatic spraying and killing function. Background Technology

[0002] Agricultural drones are unmanned aircraft used to help optimize agricultural operations, increase crop yields, and monitor crop growth. Sensors and digital imaging capabilities can give farmers a richer understanding of their fields. Using agricultural drones and collecting information from them can be very useful for improving crop yields and farm efficiency. Agricultural drones allow farmers to see their fields from the air, and this bird's-eye view can reveal many problems, such as irrigation issues, soil changes, and pests and fungal infestations.

[0003] For example, an agricultural drone (authorization announcement number CN221127992U) includes a drone body and a first visual aid device disposed within the drone body.

[0033] In this embodiment:

[0034] First, when the device needs to land stably at a location with a large height difference, the buffer pad 47 can contact the ground to cushion the impact of the landing when the drone body 11 and its upper components land. When the buffer pad 47 contacts the ground with a large height difference, it can cause the drone body 11 and its upper components to tilt. At the same time, the control host 34 controls the capacitive tilt sensor 48 to start. After the capacitive tilt sensor 48 is started, it can detect the tilt angle of the device and send the detected data to the control host 34 through the data cable for processing and control of the electric push rod 44. When the drone body 11 tilts to the left, the left electric push rod 44 can be controlled to start extending to support the left end of the device. At the same time, the right electric push rod 44 starts retracting to put the device in a parallel state. When the drone body 11 tilts forward, the two sets of electric push rods 44 at the left and right ends of the front end of the drone body 11 can be controlled to start retracting and the two sets of electric push rods 44 at the rear end can start extending and retracting to drive the buffer plate 46 to rotate and support the device. Similarly, when the drone body 11 tilts to the right or backward, the operation can be reversed.

[0035] This utility model provides an improved agricultural drone with automatic spraying function. By setting an adjustment component 4, which can automatically detect and adjust the attitude when the drone lands at a position with a large height difference, the device can automatically detect and adjust the attitude when the drone lands at a position with a large height difference to avoid tilting the drone and facilitate filling and battery replacement.
