A cutting-shaped drone rack with a stabilized arm

Abstract

The invention relates to a cutting-shaped unmanned aerial vehicle frame with a stable arm, one end of the upper swing arm and the lower swing arm is rotatably connected to the fuselage, and the other end of the upper swing arm and the lower swing arm is rotatably connected to the motor frame; The middle part of the upper swing arm is provided with a strip-shaped swing groove A, and the middle part of the lower swing arm is provided with a strip-shaped swing groove B. An elastic pull rod is connected between the upper swing arm and the lower swing arm, and one end of the elastic pull rod is fixed to the The front end of the swing slot A and the other end of the elastic pull rod are fixed to the rear end of the swing slot B; a set of transmission swing arms are rotatably connected to the top of the motor frame, and the transmission swing arms include a swing arm shell and a transmission assembly arranged in the swing arm shell , the power input wheel and the power output wheel are connected by a belt drive; a cantilever is also connected to the swing arm shell, a feedback motor is arranged in the middle of the fuselage, a feedback wheel is fixed on the output shaft of the feedback motor, and a ring is formed on the feedback wheel. The array is provided with several feedback swing arms, and a push rod is connected between the feedback swing arms and the cantilever.

Description

technical field [0001] The invention relates to a cutting-shaped unmanned aerial vehicle frame with a stable arm, belonging to the field of agricultural unmanned aerial vehicles. Background technique [0002] Most of the airfoils selected by small multi-rotor drones are standard lift airfoils, which only provide flight aerodynamic force and do not provide other functions. [0003] The cutting tools used in gardening and agriculture and forestry have cutting bodies that only have a cutting function and do not take into account other functions. [0004] At present, the high-altitude branch cutting in the garden and agriculture industry can only rely on manual climbing to the height of the tree crown, and then the cutting operation is low in efficiency and high in risk, especially in mountainous planting areas where transportation is inconvenient and large machinery is difficult to reach. Casualties happen from time to time. [0005] Therefore, the applicant studied the possi...
