Description

Technical Field

[0001] The utility model belongs to the technical field of mulching machines, and in particular relates to an agricultural mulching machine device used for agricultural mechanization. Background Art

[0002] Mulching refers to a measure of covering the ground surface with agricultural plastic film, which has the effect of reducing the impact of raindrops, preventing erosion and crust formation; it can effectively reduce the evaporation of soil moisture, conserve moisture during droughts and increase moisture after rain, promote crop absorption and growth of water, and improve the efficiency of soil moisture utilization; it can keep the soil at a suitable temperature and humidity, slow down the drop in ground temperature and last for a long time, which is conducive to the composting and decomposition of fertilizers and improve soil fertility. Mulching has low cost, is easy to use, and increases production significantly. It is a common measure that can prevent soil erosion and increase crop yields.

[0003] Most of the existing agricultural mechanized agricultural mulching machine devices only have a simple ground mulching function. The mulching rollers in the device are mostly set in fixed positions. When encountering grounds of different heights or widths, it is impossible to adjust quickly and effectively. In addition, the existing mulching machine devices cannot ensure that the ground film is fully fitted to the ground after mulching. This makes it easy for the mulched ground film to be affected by wind or other external factors, resulting in rolling and other phenomena. In view of this, we propose an agricultural mulching machine device for agricultural mechanization. Utility Model Content
