[0002] In recent years, the development of the agricultural planting industry has received policy support from various aspects. In agricultural planting, mulching is a common agricultural technology. Mulching can reduce soil moisture evaporation and maintain soil moisture. The film has good heat preservation properties, which can increase the temperature of the soil surface. Mulching can block sunlight, inhibit the growth of weeds, reduce the labor intensity and cost of manual weeding, reduce soil surface erosion, protect soil structure, prevent fertilizer from being washed away by rainwater, and make fertilizer more concentrated on the crop roots, thus improving fertilizer utilization.

However, the existing mulching machines have a complex installation structure and are not easy to operate, which reduces the efficiency of film roller installation and replacement. At the same time, the film rollers lack a speed reduction device during mulching, which makes them prone to loosening during rotation and affects the mulching effect. Utility Model Content
