The limiting rod 73 is fixed inside the side frame 7 and is located at the four corners of the side frame 7. The limiting rod 73 passes through the lifting block 71 and is slidably connected to the lifting block 71.

[0022] The robotic arm consists of a rotating column 74 and a horizontal plate 75. The bottom of the rotating column 74 is rotatably mounted on a lifting block 71. A servo motor that drives the rotating column 74 to rotate is fixed inside the lifting block 71. The horizontal plate 75 is fixed to the upper end of the rotating column 74 and is perpendicular to the rotating column 74. The gripping component includes an insertion tube 8 and an airbag 84. The upper end of the insertion tube 8 is fixed to the end of the horizontal plate 75. The bottom of the insertion tube 8 is a closed structure and is conical. An outer groove 82 is opened on the outer side wall of the insertion tube 8. An air hole 83 is opened on the side wall of the outer groove 82. The airbag 84 is fixed inside the insertion tube 8 and its position is aligned with the outer groove 82. An air pump 81 is fixed to the upper end of the horizontal plate 75. The outer surface of the airbag 84 has protrusions evenly distributed.

[0023] Working principle: When the vehicle body 1 is placed in the field, the CNC camera 34 captures the field scene, which is then driven by the controller 33. The synchronous rotation of different drive wheels 3 in the same direction ensures the linear movement of the vehicle body 1. Conversely, rotation at different speeds or in different directions enables the vehicle body 1 to turn. Ultimately, the bales can enter from the front shovel 2 and be conveyed by the angled conveyor belt 21 into the storage trough 11. The horizontal conveyor belt 15 then conveys the bales until their ends abut against the baffle 42, arranging multiple bales in the storage trough 11. When fully loaded, the vehicle can travel to the designated stacking position. Driven by the hydraulic cylinder 13, the flip plate 4 is rotated to stand the bales upright. Then, driven by the telescopic cylinder 61, the push plate 6 extends through the through hole 43, pushing the stacked bales to detach. At position 42, automatic stacking is achieved. During the process, if the bale is located in a remote position and cannot be entered from the front of the front shovel 2, the main body 1 of the vehicle can be driven to the side of the bale. The mechanical wall is rotated by the servo motor, and the mechanical arm is raised and lowered by the multi-stage hydraulic cylinder 72, so that the insertion tube 8 is inserted into the bale. After entering the bale, the air bladder 84 is inflated by the air pump 81, which increases the resistance to the extraction of the insertion tube 8. When the mechanical arm rises, the bale can be lifted synchronously. Then, the rotation of the mechanical wall allows it to enter the storage tank 11. When unloading, the air in the air bladder 84 is simply discharged, and the insertion tube 8 can be easily extracted. The operation is simpler and more convenient. When conveying the bale, the surface of the angled conveyor belt 21 and the horizontal conveyor belt 15 are provided with spikes, which can increase the surface friction and ensure the stable conveying of the bale.
