[0002] With the continuous development of social technology, various agricultural machinery and equipment for agricultural planting have appeared on the market. The emergence of agricultural machinery and equipment has greatly reduced the workload of farmers in agricultural planting and greatly improved the efficiency of agricultural planting. Among them, agricultural mulch film machines belong to the category of agricultural machinery and equipment. Agricultural mulch film machines refer to agricultural machines used to cover agricultural farmland with mulch film. The application of agricultural mulch film machines has greatly improved the efficiency of laying mulch film on farmland.

[0003] In the prior art, application number 202420535829.0 discloses a mechanized mulching assembly for agricultural farmland, including a mounting plate, supports symmetrically arranged on the left and right sides below the mounting plate, a film roller arranged in the middle below the mounting plate, and a film pressing assembly arranged in the lower inner side of the supports. The film pressing assembly includes an internally threaded sleeve that abuts against the lower inner side of the supports. The outer end of an externally threaded convex shaft connected to the internal thread of the internally threaded sleeve is fixedly connected to a second wheel frame, and a film pressing wheel is rotatably connected inside the second wheel frame. A film end limiting assembly is arranged in the middle below the mounting plate, and the film end limiting assembly includes a cylinder connected in the middle below the mounting plate.

Example

[0027] like Figure 1-4As shown, a mechanized mulching assembly for agricultural farmland according to an embodiment of this utility model includes an L-shaped mounting plate 1 and a mounting box 2. The left side of the L-shaped mounting plate 1 is fixedly connected to the mounting box 2. An adjusting arm 3 is connected to the left side of the inner wall of the L-shaped mounting plate 1.

The movable end of the first telescopic cylinder 23 drives the first groove plate 25 to descend, so that the pressure rollers 26 press the edges of the film on both sides. The pressure rollers 26 can be retracted and reset when not covering the film. When the film wound on the outer wall of the winding drum 8 is covering the ridge, the second telescopic cylinder 27 is activated. The movable end of the second telescopic cylinder 27 drives the second groove plate 28 to extend obliquely downward, so that the pressure roller 29 and the leveling bending plate 30 contact the upper surface of the film.
