Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features.

[0024] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium; it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0025] The present application proposes a spray seeding mechanical arm, as shown in Figures 1-4 , comprising a flexible connecting pipe 1, in this embodiment, the connecting pipe 1 comprises a rubber hose, and a slip knot sleeve connected to both ends of the rubber hose, by adopting the rubber hose, the sharp bend of the pipeline can be avoided, and the rubber hose can better adapt to the swing or rotation angle compared with the rigid connecting pipe;

[0026] One end of the connecting pipe 1 is fixedly connected to the platform 2, and the other end of the connecting pipe 1 is connected with the spray gun seat 3. The spray gun seat has a structure including a connecting pipe and a connecting seat. One end of the connecting pipe is connected with the connecting pipe 1, and the other end of the connecting pipe is connectable with a spray gun. Although the present example introduces the structure of spraying and seeding one connecting pipe, the number of connecting pipes can be increased or reduced according to actual needs to realize the spraying and seeding of different types of media by those skilled in the art.

[0027] The connecting seat of the spray gun seat 3 is fixedly connected with a connecting rod A 4, and the connecting rod A 4 is rotatably connected with a connecting rod B 5. The connecting rod A 4 and the connecting rod B 5 are rotatably connected to form a joint of the spraying and seeding mechanical arm.

[0028] A support 6 is arranged on the platform 2. The support 6 includes a guide sleeve A 61, a guide sleeve B 62, and a support plate 63. The guide sleeve A 61 and the guide sleeve B 62 are connected to the support plate 63, and the support plate 63 is connected to the platform 2 and extends outward from the platform 2. The connecting rod B 5 is rotatably connected with the support 6.

[0029] Further, a driving mechanism 7 is arranged. The driving mechanism 7 drives the connecting rod A 4 to make vertical movement while rotating around the output end of the driving mechanism and the rotation point of the connecting rod A 4, so that the bending shape of the connecting pipe 1 changes uniformly.

[0030] The movement shape of the connecting pipe changes uniformly through the driving mechanism, which can reduce the wear of the connecting pipe and the pressure loss in the pipeline, improve the lift, and avoid blockage.

[0031] Further, the driving mechanism is any one of a screw mechanism, a pneumatic cylinder, a hydraulic cylinder, an electric cylinder, and a gear rack mechanism. In the present example, the driving mechanism is a screw mechanism, which specifically includes a lead screw 71 rotatably connected with the connecting rod A 4, and a lead screw nut 72 screw-connected with the lead screw 71. The lead screw nut 72 is connected with the guide sleeve A 61 and the guide sleeve B 62, respectively. The lead screw nut 72 is rotated to make the lead screw 71 move up and down, thereby driving the connecting rod A 4 to move. In order to facilitate the control of the lift of the spraying and seeding mechanical arm, a hand wheel 73 is arranged at the lead screw nut 72. The hand wheel 73 is rotated to make the lead screw move up and down.

[0032] In order to realize a wide horizontal spraying angle, a rotary flange 9 is connected below the platform 2. The top end of the rotary flange 9 is fixedly connected with the platform 2, and a mechanical arm fixing seat 11 is further connected with the rotary flange 9. The mechanical arm fixing seat 11 serves as a support for the spraying and seeding mechanical arm. The platform can rotate relative to the mechanical arm fixing seat 11 through the rotary flange 9, so as to realize the horizontal rotation of the spraying and seeding mechanical arm, thereby increasing the spraying angle and realizing wide spraying.

[0034] In order to control the rotation angle of the platform, a handrail is arranged at the platform, and the rotation angle of the platform can be adjusted by rotating the handrail.

[0035] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
