[0002] Ground film is a plastic film, usually made of polyethylene and other materials, which is widely used in agricultural production. It can keep warm, keep moisture, suppress weeds, and increase production. With the widespread application of mechanization in agricultural production, ground film machines have emerged. Their main function is to lay ground film on the surface of farmland, covering the soil where crops grow, reducing the labor intensity of laying ground film manually and improving work efficiency.

[0003] During use, the existing mulching machine can smoothly unfold the mulch and cover the farmland. However, since the soil in the farmland is newly plowed and loose, and is in an uneven state, large gaps are likely to exist on both sides of the covered mulch, resulting in poor heat preservation and moisture retention effects. Therefore, we propose an agricultural mulching machine for agricultural mechanization. Utility Model Content

[0025] The effect achieved by the entire embodiment 1 is that the farm tractor pulls the machine to move in the farmland, the ground film is covered on the soil surface, and the two sets of film pressing wheels 51 are respectively located on both sides of the ground film roll, pressing the two sides of the ground film, wherein the film pressing wheel 51 is subjected to the upward force of the soil during the movement, and this force causes the built-in rod 53 to slide and shrink in the outer sleeve 55, and the spring 54 located between the ring buckle 56 and the wheel frame 52 is compressed and deformed to generate elastic force, and this elastic force reacts on the wheel frame 52, so that the film pressing wheel 51 When subjected to force, the ground film is pressed to fit the soil surface.

[0027] The effect achieved by the entire embodiment 2 is that the film reel 35 with the ground film roll is clamped on the upper side of the frame 1, and the end of the film roll passes through the gap between the bottom roller assembly 31 and the auxiliary roller assembly 32, surrounds the bottom roller assembly 31 and extends backward, and is fixed in the initial position.

[0028] Working principle: When using the agricultural mulching machine for agricultural mechanization, the machine is connected to the farm tractor through the frame 1, and the film reel 35 with the mulch film roll is clamped on the upper side of the frame 1. The end of the film roll passes through the gap between the bottom roller assembly 31 and the auxiliary roller assembly 32, surrounds the bottom roller assembly 31 and extends backward, and is fixed in the initial position. Under the traction of the farm tractor, the two iron wheels 2 move in a straight line in the farmland.

The spring 54 located between the ring buckle 56 and the wheel frame 52 is compressed and deformed to generate an elastic force, which reacts on the wheel frame 52, so that the film pressing wheel 51, under the condition of being subjected to a force, presses the ground film to fit the surface of the soil. According to the unevenness of the soil surface, the elastic force changes accordingly, so that the film pressing wheel 51 always presses the ground film to fit the surface of the soil, and the blades of the plowshares 4 on both sides face inward. After the ground film is pressed by the film pressing wheel 51, the two groups of plowshares 4 turn up the soil on the outside and directly cover both sides of the ground film to avoid gaps at the edge of the ground film, thereby completing the film covering.
