The cutting knife 406 moves stably in the groove through the groove, and the dust suction pipe at the bottom absorbs, collects and stores the cut debris to avoid affecting the environment.

[0035] Working principle: When used, Figure 1 and Figure 5 As shown, the agricultural film is passed through the bottom of the second limiting rod 803, and under the elastic action of the third spring 804, the second movable block 802 is pushed to move the second limiting rod 803 downward, so that the agricultural film is attached to the surface of the support frame 1, as shown in FIG. Figure 2 and Figure 4 As shown, the end of the agricultural film is placed on the surface of the placement rod 303, and the first limiting rod 503 is attached to the placement rod 303 under the elastic action of the first spring 504 to fix the agricultural film, and the cleaning wheel 507 is rotated to the upper surface of the agricultural film through the first limiting rod 503.

The display screen on the surface of the support frame 1 is observed. After the length is determined, as shown in FIG. Figure 3 and Figure 7 As shown, the hydraulic rod 401 is started, and the hydraulic rod 401 drives the lifting plate 402 to move downward to the surface of the agricultural film. The pressing plates 703 on both sides make the agricultural film fit the surface of the support frame 1. At the same time, the connecting column 702 moves upward to squeeze the second spring 704, so that the second spring 704 is deformed to fix the agricultural film on both sides of the cutting knife 406. Then the motor 403 is started to drive the screw 404 to rotate, so that the moving block 405 drives the cutting knife 406 to move horizontally along the screw 404 to cut the agricultural film. The cutting knife 406 moves stably in the groove, and the dust suction pipe at the bottom absorbs, collects and stores the cut debris. Figure 4 and Figure 6 As shown, after cutting, the crank handle 604 is turned to drive the placement rod 303 to rotate and roll up the agricultural film on the surface. At the same time, the surface of the rolled agricultural film is wiped by the cleaning wheel 507. After the rolling is completed, the agricultural film is fixed with an adhesive sticker, and then the insertion rod 602 is pulled outward to make the limiting ring 603 fit the other side of the second movable groove 601, so that the end of the insertion rod 602 is separated from the placement rod 303, and the placement rod 303 is taken out. The above is the entire working principle of the utility model.
