[0002] High-standard farmland refers to arable land that is flat, concentrated and contiguous, has complete facilities, supporting farmland, fertile soil, good ecology, strong disaster resistance, and is compatible with modern agricultural production and management methods. It is high-yield and stable, and is designated as permanent basic farmland. High-standard farmland covers a wide range and a large area. When farmland mapping is needed, drones are generally used for aerial photography and mapping.

[0003] The existing high-standard farmland drone aerial photography and mapping devices have certain defects when used. The bottom of the drone has a support rod structure, which is used to support the drone after landing. However, these support rods will increase resistance after the drone takes off, affecting the flight speed of the drone. Moreover, the support rod structure causes the size of the drone to increase. These support rods are prone to accidental collision when the drone is flying, resulting in poor use of the drone aerial photography and mapping devices. Therefore, improvements are now made to high-standard farmland drone aerial photography and mapping devices. Utility Model Content

[0029] Reference Figure 5 The support part 6 includes a support rod 61 and a second connecting frame 62. One end of the support rod 61 is fixedly connected to a connecting shaft 63. A third connecting frame 64 is fixedly installed on the upper side of the support rod 61. A rubber pad 65 is fixedly installed on the other end of the support rod 61. The support rod 61 plays a supporting role and is used to contact the ground for support after the drone lands. The rubber pad 65 is anti-slip and buffered to ensure the stability of the drone after landing and prevent the fuselage 1 from directly contacting the ground and causing damage to the drone.

[0030] Among them, the connecting frame 62 is fixedly installed on the lower side of the rotor bracket 3, and the support rod 61 is hinged to the second connecting frame 62 through the connecting shaft 63.
