Problems solved by technology

Due to field terrain factors, as well as the complex structure and heavy weight of the original landing gear, it is not suitable for agricultural production operations. Therefore, a landing device with light weight and simple structure is sought to realize the fixed-wing UAV in the field. The landing of the canopy is a useful supplement to the current agricultural aviation application technology

Embodiment 1

[0032] Such as figure 1 , 2 As shown, the present embodiment is a field crop canopy landing device suitable for fixed-wing unmanned aerial vehicles, including a fixed support frame, a load buffer device, and a take-up and release device. The above-mentioned components are connected by corresponding connectors. The overall landing device is fixed under the fixed-wing UAV, and the retraction and retraction of the glass fiber gauze, which acts as a load buffer, is controlled by the ground device, without affecting the normal flight of the fixed-wing aircraft. Below in conjunction with accompanying drawing its structure is described in detail as follows.

[0033] In this embodiment, the fixed support frame includes a bottom frame and two hangers, and the two hangers are respectively arranged on both sides of the bottom frame. Middle bar 12 and support rear bar 13, support front bar 11 two ends are respectively connected with two front-end supports 2 one ends of both sides, and f...

Abstract

The invention discloses a field crop canopy landing device suitable for a fixed-wing unmanned aerial vehicle and a method thereof. The device includes a fixed support frame, a load buffer device, and a take-up and release device. The fixed support frame includes a base frame and several hangers. The landing device is installed under the UAV through a hanger. The chassis includes a front support, a support side arm, a support front pole, a support middle pole and a support rear pole. Vertically connected, the support middle rod is connected to the front ends of the support side arms at both ends, and the two ends of the support rear rod are connected to the ends of the support side arms on both sides respectively; the load buffer device includes a glass fiber gauze and a sliding rod, and one end of the glass fiber gauze It is fixed on the support middle rod, and the other end is fixed on the slide bar, which is parallel to the support front bar, and the slide bar moves back and forth along the support side arm under the drive of the take-up and pay-off device. The invention can ensure that the drone can safely land on the canopy of field crops without affecting the normal flight of the drone.

Description

technical field [0001] The invention relates to the technical field of agricultural equipment, in particular to a field crop canopy landing device and method suitable for fixed-wing unmanned aerial vehicles. Background technique [0002] At present, drones are playing an incomparable role in agricultural production, such as widely used pesticide spraying operations. In addition, due to its advantages of lightness, flexibility, and ease of use, the UAV can carry sensors to detect and analyze field crop growth information, soil moisture and nutrition status, etc., so as to realize precise control of agricultural production. Once problems are found, they can be taken in time. Countermeasures to save resources and reduce losses. [0003] The main types of UAVs used in agricultural production are multi-rotor, single-rotor, and fixed-wing aircraft. When multi-rotor and single-rotor drones are operating in the field, they cannot guarantee long-term battery life due to their own w...
