Undercarriage for plant protection unmanned aerial vehicle

Abstract

The invention belongs to the technical field of plant protection unmanned aerial vehicles. The invention relates to an undercarriage for a plant protection unmanned aerial vehicle. The undercarriage comprises a body and a bracket; four supports are symmetrically fixed to the two sides of the outer side wall of the body along the vertical center line. T-shaped pieces are fixed to the outer side walls of the four supports; a transverse rod is fixed between two T-shaped pieces, and a connecting rod is fixed between the two transverse rods; connecting pieces are fixed to the edges of the bottoms of the outer side walls of the four supports, and floor rods penetrate through the interiors of two connecting pieces. Lantern rings sleeve the outer side walls of the two floor rods; the outer side wall of each lantern ring is connected with a buckling strip, a flat plate is connected between the two buckling strips, and a through groove is formed in the front surface of the flat plate. In the working process of the plant protection unmanned aerial vehicle, the flat plate and an undercarriage on the unmanned aerial vehicle are in a static state, the flat plate can separate vegetation from theundercarriage, and the situation that the vegetation is wound around the undercarriage, and the using effect of the device is affected is avoided.

Description

technical field [0001] The invention belongs to the technical field of plant protection drones, and in particular relates to a landing gear for plant protection drones. Background technique [0002] Plant protection drone, also known as unmanned aerial vehicle, is an unmanned aircraft used for agricultural and forestry plant protection operations. This type of unmanned aircraft is composed of three parts: a flying platform, a navigation flight control, and a spraying mechanism. Wings, helicopters, and multi-axis aircraft can realize spraying operations through ground remote control or navigation flight control. They can spray chemicals, seeds, powders, etc. Plant protection drones have the characteristics of good control effect, high safety, and low comprehensive cost. [0003] There are following problems in existing technology: [0004] 1. There are certain deficiencies in the landing gear of the plant protection drones on the market. When the plant protection drones are ...

AI Technical Summary

Problems solved by technology

[0004] 1. There are certain deficiencies in the landing gear of the plant protection drones on the market. When the plant protection drones are working in the air, sometimes because of the surrounding environment and the landing gear of the drones are made of tubular round rods. Composed, it is easy to cause the landing gear on the UAV to sink into the vegetation, and sometimes the winding is too tight to make it impossible to disengage, which affects the use effect;

[0005] 2. There are many types of plant protection drones, some for spraying pesticides, and some for spraying pollen. For plant protection drones such as spraying mixed liquid, some liquid will be spilled when the drone is loaded with liquid. The outside of the device makes the surrounding soil soft. Due to the heavy volume of the drone, there will be a downward force and sink into the soil, which will easily cause the landing pole to sink into the soil, which is not conducive to the flight of the plant protection drone. In addition, the plant protection has no There is a lot of pressure when the man-machine is flying and landing, and the landing gear is easily damaged;

[0006] 3. The plant protection UAV can be used in good weather, but the weather is changeable. Sometimes in a foggy environment, it is difficult for the operator to see the long-distance UAV, and it is impossible to grasp the flight direction of the plant protection UAV. The scope of application of plant protection drones
