Embodiment 1

[0035] like Figure 1 to Figure 10As shown, the present invention provides a spraying device for a plant protection drone, including a mounting frame 1 installed on the body, and the mounting frame 1 is provided with a swing beam 2, a spray bar 3, a linkage gear 4, a shift fork assembly 5, The switch assembly 7, the drive assembly 8 and the lock lever 10, one end of the swing beam 2 is connected to the linkage gear 4 through the turntable 13, so that the turntable 13 is driven to rotate by the rotation of the linkage gear 4, thereby driving the swing beam 2 around the center of the linkage gear 4 The spray bars 3 are hinged through the hinge assembly 6, so that the spray bars 3 on both sides of the hinge assembly 6 can rotate relatively; the end of the spray bar 3 is movably connected with one end of the swing beam 2 to pass 2 to adjust the vertical rotation angle of the spray bar 3, so as to realize the multi-angle spraying of the spray bar 3; The rotation angle of the verti...

Embodiment 2

[0040] like Figure 9 and Figure 10 As shown, in combination with the technical solution of Embodiment 1, in this embodiment, the shift fork assembly 5 includes a shift fork 51 and a pull rod 52, a chute 111 is provided on the first rotating shaft 11, and the first linkage gear 41 is located in the chute 111; One end of the first linkage gear 41 is provided with an annular groove 411, one end of the shift fork 51 is located in the annular groove 411, the other end of the shift fork 51 is connected with the pull rod 52, and the pull rod 52 is connected with the switching assembly 7 to switch through the switching assembly 7 Pull the pull bar 52 and the lock bar 10 to perform telescopic movement.

[0041] Specifically, the switching assembly 7 includes a rotating cylinder 71 and a limiting member 72, the limiting member 72 is fixedly connected to the mounting frame 1, the pull rod 52 and the locking rod 10 are slidingly connected to the limiting member 72; the rotating cylinde...

Embodiment 3

[0043] like image 3 As shown, in combination with the technical solution of Embodiment 2, in this embodiment, the sliding locking assembly 9 includes a support plate 91, a push rod 92, a U-shaped piece 93 and a U-shaped ring 94, and the support plate 91 is connected to the mounting frame 1. Push rod 92 is slidably connected on support plate 91; U-shaped part 93 is connected to one end of push rod 92, and the other end of push rod 92 is provided with hook plate 95; The shape part 93 is connected to the end of the limit rod 96, and the first spring 97 is sleeved on the limit rod 96; the guide rod 43 is rotated by the linkage gear 4 to enter the U-shaped ring 94, and drives the U-shaped ring 94 to perform a straight line. During the linear movement, the U-shaped ring 94 pushes the push rod 92 to perform a linear movement, thereby driving the hook portion 98 to perform a linear movement, so as to limit and support the swing beam 2 .

[0044] Specifically, such as Figure 12 and...

Abstract

The invention discloses a spraying device of a plant protection unmanned aerial vehicle. By arranging the linkage gear and the hinged spraying rod, the linkage gear rotates to drive the swing beam to pull the spraying rod to rotate in the vertical direction so as to adjust the angle of the spraying rod in the vertical direction, and therefore the spraying rod can spray pesticide in the horizontal direction and the vertical direction. Meanwhile, a V-shaped structure defined by the spraying rods can be used for obliquely spraying pesticide to the roots and trunks of the plants, the pesticide spraying modes of the spraying rods are effectively increased, and therefore the flexibility of the spraying rods is improved, waste of pesticide powder is reduced, and the pesticide spraying coverage rate of the plants is increased; besides, a shifting fork assembly is pulled through a switching assembly to drive a first linkage gear to linearly slide on a first rotating shaft, so that meshing of the first linkage gear and a second linkage gear is disconnected, and a driving assembly can independently drive the first linkage gear to adjust the vertical angle of a first spraying rod; therefore, the first spraying rod and the horizontal second spraying rod can spray pesticide to plants at multiple angles, and the pesticide spraying flexibility of the spraying rods is further improved.

Description

technical field [0001] The invention relates to the technical field of rubber cutting, in particular to a spraying device for a plant protection drone. Background technique [0002] With the development of drone technology, drones are constantly being used in different fields; in the fields of agriculture, forestry and agricultural planting, drone spraying has gradually become a new spraying method; drone spraying has a spraying speed Fast, high degree of automation, suitable for large-scale coverage spraying, greatly changed and promoted the development of traditional agricultural technology, and improved agricultural productivity; the spraying device of the plant protection drone or plant protection sprayer of the prior art The spraying methods are all in the form of horizontal spraying. The spraying coverage is mainly from the top of the plants, and the coverage of the roots and trunks of the plants is less. For the plants growing in rows, the horizontal spraying of the p...
