[0002] Agricultural equipment refers to various mechanical devices used in agricultural production, primarily for crop cultivation and animal husbandry, as well as the initial processing and handling of agricultural and livestock products. Agricultural equipment plays a crucial role in agricultural production, improving efficiency, reducing labor intensity, and promoting agricultural modernization. Mulching machines, a common type of agricultural equipment, are primarily used for covering crops with plastic film. This protects crops by covering them with a thin film, providing benefits such as warming, water retention, fertilizer retention, improving soil physicochemical properties, enhancing soil fertility, suppressing weed growth, and mitigating diseases. However, most common mulching machines have a fixed, integrated internal structure, which often allows for adjustments based on soil conditions, resulting in poor mulching effectiveness and ultimately reducing the overall efficiency of the equipment, failing to adequately meet the needs of crops.

[0003] During the design process of this utility model, the following problems were found in the existing technology: Most common mulch film covering machines have an integrated fixed structure inside. When the soil spacing or mulch film roller is long, it is often inconvenient to make corresponding adjustments inside the mulch film covering machine, resulting in poor mulch film covering effect, which in turn reduces the use effect of agricultural equipment and cannot well meet the needs of crops.

[0025] In this embodiment, as Figure 1 and Figure 2 As shown, the fixing frame 1 has an I-shaped structure, and both the upper and lower ends of the fixing frame 1 have embedded docking grooves 102. The abutment plate 105 and the inner wall of the docking groove 102 form a sliding connection structure.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the side frame 2 is composed of two L-shaped frames connected vertically. One L-shaped end of the side frame 2 is connected to the mating groove 102 in an insert connection structure, and the other L-shaped end of the side frame 2 is connected to the abutment plate 105 in a fitting connection structure.
