[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-3 The utility model provides a technical solution: a folding mechanism of a folding spray rod of a plant protection machine, comprising a fuselage 1, a connecting plate 2 is provided on the side wall of the fuselage 1, a mounting plate 3 is hinged on the side wall of the connecting plate 2, and a cushion block 4 is provided on the lower end surface of the mounting plate 3; a butterfly hinge 5 is installed at the lower end of the cushion block 4; a cushion plate 6 is provided on the butterfly wing of the butterfly hinge 5, a spray rod 7 is provided on the cushion plate 6, and a spray head 8 is provided at the end of the spray rod 7. When in use, the butterfly hinge 5 pulls out the spray rod 7 to facilitate the operation of the spray rod 7. The connecting plate 2 and the mounting plate 3 are hinged to facilitate the adjustment of the angle between the mounting plate 3 and the connecting plate 2. The setting of the cushion block 4 and the cushion plate 6 facilitates the installation of the butterfly hinge 5, and the length and thickness of the cushion block 4 and the cushion plate 6 are adjusted according to the requirements of the use environment.

[0018] Specifically, the connecting plate 2 and the mounting plate 3 are hinged by a thick butterfly hinge 9. At the same time, the thick butterfly hinge 3 and the butterfly hinge 5 are provided with angle limit blocks 10. The angle limit blocks 10 prevent excessive rotation between the connecting plate 2 and the mounting plate 3 and between the mounting plate 3 and the spray rod 7. The thick butterfly hinge 9 has double butterfly wings that are hinged to each other, one side of the butterfly wing is fixedly connected to the connecting plate 2, and the other side of the butterfly wing is fixedly connected to the mounting plate 3.
