The two ends of the clamping hydraulic cylinder I 0102 are respectively hinged to the clamping arm I 0101 and the clamping arm II 0104. The opening and closing angle between the clamping arm I 0101 and the clamping arm II 0104 is adjusted by the telescopic movement of the clamping hydraulic cylinder I 0102. The clamping arm connecting plate 0103 is fixed to the left side of the clamping arm III 0112. The clamping arm III 0112 is fixed in front of the lifting mechanism 0111.

When the stretching film is pulled out, the film guiding roller I 0705 and the film guiding roller II 0706 have an obstructive effect on the stretching film. As the film guiding device 07 rotates, the stretching film is stretched.

[0020] Working principle: This baling wrapper is towed behind the tractor on the side and powered by the tractor. When using this machine, the clamping arms I 0101 and clamping arms II 0104 in the pickup device 01 are horizontally placed and at a certain distance from the ground. When the machine moves forward to the rear of the round bale, the clamping hydraulic cylinders I 0102 and clamping hydraulic cylinders II 0105 contract, and the clamping arms I 0101 and clamping arms II 0104 open, making the clamping arm II 0104 parallel to the bale axis. The bale is located between the two clamping arms. The clamping hydraulic cylinder I 0102 extends to pick up the bale. At the same time, the clamping hydraulic cylinder II 0104 extends to adjust the bale posture to make the bale parallel to the machine. At this time, the lifting hydraulic cylinder 0106 contracts, and the lifting mechanism 0111 rises, driving the bale to the specified position and rolling it between the winding film roller I 0108 and the bale unloading device 05. The pickup device 01 returns to its original position. The hydraulic motor II 0109 drives the winding film roller I 0108 to rotate through the reducer 0110, and then drives the bale to rotate. After that, the hydraulic motor I 02 drives the winding drive device 10 to rotate, and then drives the gear track 06 to rotate, making the film guiding device 07 fixed on the gear track 06 revolve around the bale. The above mechanisms complete the winding film action according to the movement. One end of the stretch film is pressed by the film pressing hook 0801 and film pressing rubber block 0804 in the film cutting device 08, pulled out through the film guiding roller I 0705 and film guiding roller II 0706, and wound on the surface of the bale. After the winding film is completed, the return electric cylinder 0807 in the film cutting device 08 extends and then contracts. After the film pressing hook 0801 hooks and pulls back the stretch film, it cooperates with the film pressing rubber block 0804 to press the stretch film. The return electric cylinder 0807 continues to contract, and the film cutting blade 0802 cuts off the stretch film. The bale unloading hydraulic cylinder 0504 in the bale unloading device 05 contracts, and the bale drops to the ground. The bale unloading hydraulic cylinder 0504 resets, and the bale unloading device 05 returns to the initial position to prepare for the next winding film operation.

[0021] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
