Embodiment 1

[0028] Such as figure 1 , 5 As shown in and 6, a quick-release structure of the arm of a plant protection drone includes a machine arm 1 and a machine arm base 2, and the machine arm base 2 is provided with a connection hole 3 that is plugged with the machine arm 1, and the connection hole 3 is connected to the machine arm 1. The machine arm 1 is coaxially arranged, the machine arm seat 2 on the side of the connection hole 3 is provided with a rotation groove 4, and a limit block 5 is rotated in the rotation groove 4, and a side of the limit block 5 close to the connection hole 3 is provided with a The assembly groove 6 attached to the side wall of the machine arm 1, the block 7 is fixed in the assembly groove 6, the side wall of the machine arm 1 is provided with a groove 8 matching with the block 7, the limit block 5 and the arm seat 2 An openable locking piece is arranged between them.

[0029] The usage method of this embodiment: Insert one end of the machine arm 1 into ...

Embodiment 2

[0031] This embodiment is basically the same as Embodiment 1, except that the lower end of the limit block 5 is connected to the machine arm base 2 in rotation through plug screws 9, the plug screws 9 are arranged along the axial direction of the machine arm 1, and the limit block The upper end of 5 is provided with the first arc ring 10, is provided with threaded hole 11 in the second arc ring 12, and the upper end of machine arm base 2 is provided with the second arc ring 12 that cooperates with the first arc ring 10, lock The fastener includes a spring 13, a locking screw 14 and a handle 15. The lower end of the locking screw 14 slides through the spring 13 and the handle 15 in turn, and is fixedly connected with the threaded hole 11. The lower end of the handle 15 is provided with a limiting groove 16, and the handle 15 is set on the outside of the first arc-shaped ring 10 and the second arc-shaped ring 12 through the limit groove 16, and the locking of the handle 15 is rea...

Embodiment 3

[0033] This embodiment is basically the same as embodiment one and / or two, the difference is: as Figure 2-7 As shown, the end of the machine arm 1 close to the machine arm base 2 is provided with the machine arm end terminal board 17, and the machine arm terminal terminal board 17 is provided with the machine arm terminal positive pole incoming line 18 and the machine arm terminal negative pole for powering the machine arm 1 motor. The incoming line 19, the end of the machine arm base 2 away from the machine arm 1 is provided with a fuselage terminal terminal board 20 that cooperates with the machine arm terminal terminal board 17, and the fuselage terminal terminal board 20 is fixed on the fuselage of the drone. The terminal terminal board 20 is connected with the negative outlet of the fuselage terminal and the positive outlet of the fuselage. After the machine arm 1 is inserted into the connection hole 3, the terminal board 17 at the machine arm end is offset against the t...

Abstract

The invention provides an arm quick-release structure of a plant protection unmanned aerial vehicle and a usage method. The quick-release structure comprises a machine arm and a machine arm base. A connecting hole connected with the vehicle arm in an inserting manner is formed in the vehicle arm seat; a rotating groove is formed in the arm base on one side of the connecting hole, a limiting blockis rotationally arranged in the rotating groove, an assembling groove attached to the side wall of the arm is formed in the side, close to the connecting hole, of the limiting block, a clamping blockis arranged in the assembling groove, a groove matched with the clamping block is formed in the side wall of the arm, and an openable locking part is arranged between the limiting block and the arm base. The structure is simple, the connecting strength and stability of the vehicle arm and the vehicle arm base are guaranteed, and operation is quick and convenient.

Description

technical field [0001] The invention relates to the technical field of drones, in particular to a quick-dismantling structure of an arm of a plant protection drone and a method for using it. Background technique [0002] At present, the arms of most plant protection drones on the market are foldable or easy to disassemble, in order to facilitate the transportation and transfer of drones. Existing foldable arms are usually folded vertically, resulting in a larger vertical storage or transportation space, while the foldable arms have complex connection structures to ensure the strength and stability of the arm connection, making it difficult to disassemble And reinstallation, affecting the convenience of drone use. [0003] CN109229350A discloses a quick-release structure for the arm of a multi-rotor UAV. The fulcrum B is threadedly connected with the sleeve to realize the connection between the limit position of the arm and the fulcrum B. A card slot is formed, and one end ...
