[0020] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0021] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0022] Embodiment 1, as Figures 1-4 shown, the present invention provides a fully automatic pneumatically driven loading arm, including: a top plate 12, the bottom of the top plate 12 is fixedly connected with a first pneumatic motor 5, the output end of the first pneumatic motor 5 movably penetrates through the top of the top plate 12, the output end of the first pneumatic motor 5 is fixedly connected with a lead screw 3, the outer surface of the lead screw 3 is threadedly connected with a support column 1, the outer surface of the support column 1 is fixedly connected with a mounting plate 2, the outer surface of the mounting plate 2 is fixedly connected with a connector 11, the top of the connector 11 is fixedly connected with an outer tube 9 through a first rotary joint, the top of the outer tube 9 is fixedly connected with a rotating tube 8 through a second rotary joint, the rear end surface of the rotating tube 8 is fixedly connected with an outer tube 9 through a third rotary joint, the bottom of the mounting plate 2 is fixedly connected with a second pneumatic motor 6, the output end of the second pneumatic motor 6 is fixedly connected with a first driving gear 14, the outer surface of the outer tube 9 near the bottom is fixedly connected with a first driven gear 15, the outer surfaces of the first driving gear 14 and the first driven gear 15 are meshed, the outer surface of the inner tube 7 is fixedly connected with a third pneumatic motor 19, the output end of the third pneumatic motor 19 is fixedly connected with a second driving gear 18, the outer surface of the rotating tube 8 near the bottom is fixedly connected with a second driven gear 17, the outer surfaces of the second driven gear 17 and the second driving gear 18 are meshed, the outer surface of the outer tube 9 is fixedly connected with a connecting block 22, the top of the connecting block 22 is sequentially rotatably connected with a pneumatic cylinder 20 and a spring cylinder 21, the outer surface of the rotating tube 8 is fixedly connected with a support base 23, the driving ends of the pneumatic cylinder 20 and the spring cylinder 21 are both in a matching setting with the support base 23, and the front end surface of the outer tube 9 is fixedly connected with a vertical tube 10 through a third rotary joint.

[0023] The effect achieved by the entire Embodiment 1 is that the driving end of the pneumatic cylinder 20 is in a rotational relationship with the support base 23. The spring cylinder 21 can be adjusted on the support base 23 through a nut. During use, the second pneumatic motor 6 drives the first driving gear 14 to rotate, driving the first driven gear 15 to rotate, so as to realize the horizontal rotation of the inner pipe 7 and the outer pipe 9. By starting the third pneumatic motor 19 to drive the second driving gear 18, driving the second driven gear 17 to rotate, the rotating pipe 8 rotates, thereby driving the outer pipe 9 to rotate along the inner pipe 7. At the same time, under the action of the pneumatic cylinder 20, a main power source can be provided to provide continuous driving force, while the spring cylinder 21 is mainly used to provide a return force. Thus, under the start of the pneumatic cylinder 20 and in cooperation with the use of the support base 23 and the connecting block 22, the outer pipe 9 can be driven to perform angle adjustment along the rotating pipe 8, so as to adjust the position of the vertical pipe 10. At the same time, during the use process, by starting the first pneumatic motor 5, the lead screw 3 rotates on the top plate 12 and the bottom plate 13, so that the support column 1 moves up and down along the axial direction of the lead screw 3, realizing the overall height adjustment of the loading and unloading arm to adapt to the feeding requirements at different heights. Through the coordinated operation of multiple pneumatic components, the overall height adjustment of the loading and unloading arm and the position adjustment of the vertical pipe 10 are realized automatically, improving the automation degree and flexibility of the loading and unloading operation.

[0024] Embodiment 2 is as follows Figures 1-4 As shown, the bottom of the lead screw 3 is rotatably connected to the bottom plate 13, and guide rods 4 are symmetrically and fixedly connected between the outer surfaces of the bottom plate 13 and the top plate 12. Both of the two guide rods 4 pass through the support column 1 movably.

[0025] The effect achieved by the entire Embodiment 2 is that when the support column 1 is moving, the guide rod 4 can ensure that the support column 1 remains stable during the lifting process, preventing deflection or shaking.

[0026] Working principle: During use, the second pneumatic motor 6 drives the first driving gear 14 to rotate, driving the first driven gear 15 to rotate, so as to realize the horizontal rotation of the inner pipe 7 and the outer pipe 9. By starting the third pneumatic motor 19 to drive the second driving gear 18, the second driven gear 17 is driven to rotate, causing the rotating pipe 8 to rotate, thereby driving the outer pipe 9 to rotate along the inner pipe 7. At the same time, under the action of the pneumatic cylinder 20, a main power source can be provided to offer continuous driving force, while the spring cylinder 21 is mainly used to provide a return force. Thus, when the pneumatic cylinder 20 is started and in cooperation with the use of the support base 23 and the connecting block 22, the outer pipe 9 can be driven to adjust the angle along the rotating pipe 8, so as to adjust the position of the vertical pipe 10. Meanwhile, during the use process, by starting the first pneumatic motor 5, the lead screw 3 will rotate on the top plate 12 and the bottom plate 13, and thus the support column 1 will move up and down along the axial direction of the lead screw 3. The guide rod 4 can ensure the stability of the support column 1 during the lifting process, realizing the overall height adjustment of the loading and unloading arm to adapt to the feeding requirements at different heights. Through the collaborative work of multiple pneumatic components, the overall height adjustment of the loading and unloading arm and the position adjustment of the vertical pipe 10 are realized automatically, improving the automation degree and flexibility of the loading and unloading operation.

[0027] The wiring diagrams of the first pneumatic motor 5, the second pneumatic motor 6, the third pneumatic motor 19 and the pneumatic cylinder 20 in the present utility model belong to the common knowledge in the field. Their working principles are already known technologies, and their models are selected according to actual use. Therefore, the control methods and wiring arrangements of the first pneumatic motor 5, the second pneumatic motor 6, the third pneumatic motor 19 and the pneumatic cylinder 20 will not be explained in detail.

[0028] The above are only the preferred embodiments of the present utility model, and do not limit the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
