The plastic film roller 4 is sleeved inside the mounting cylinder 6, and is fixed to the plastic film roller 4 by the locking screws 7 passing through the side wall of the mounting cylinder 6, thereby realizing the detachable connection of the plastic film roller 4 for easy and quick replacement.

[0017] refer to Figure 5 The adjustment assembly includes two adjusting screws 14, an adjusting handle 15, and a guide rod 16. The two adjusting screws 14 are threaded through the two side walls of the mulch film laying frame 1, with one end rotatably connected to the mulch film clamping plate 3 via a bearing 5, and the other end welded to the adjusting handle 15. The guide rod 16 is fixedly connected to the two mulch film clamping plates 3 at both ends and slides against the side walls of the mulch film laying frame 1. Rotating the adjusting handle 15 allows the mulch film clamping plates 3 to slide along the guide rod 16 via the threaded transmission of the adjusting screws 14, enabling flexible adjustment of the distance between the two mulch film clamping plates 3 to accommodate mulch film rollers 4 of different widths.

[0018] refer to Figure 2 , Figure 5 The soil covering mechanism includes two connecting frames 8, a plow blade mounting frame 9, and a plow blade body 10. The connecting frames 8 are fixed to the rear ends of the plastic film laying frame 1 on both sides. The plow blade mounting frame 9 is slidably connected to the connecting frames 8 via a slider. The plow blade body 10 is fixedly installed at the bottom of the plow blade mounting frame 9 with bolts. A connecting plate 11 is welded between the plow blade mounting frame 9 and the plastic film clamp 3, so that when the plastic film clamp 3 moves, the plow blade mounting frame 9 can be slid synchronously through the connecting plate 11.
