[0002] A half-film machine with a soil covering function is a kind of agricultural machinery with specific functions, mainly used for semi-film covering and soil covering operations during sowing or planting. This kind of machinery combines the two technologies of film covering and soil covering to meet the needs of different crop plantings. The half-film machine with a soil covering function can improve planting efficiency, reduce manual operations, and lower costs. At the same time, due to its characteristic of partially covering the film, compared with full-film covering, the requirements for the land of semi-film covering are relatively lower, and the applicable range is wider. For the existing half-film machines, during the use process, due to the use of the semi-film form for operation, there are relatively high requirements for the looseness, moisture content, and impurity content of the soil, and the soil surface needs to be flat, otherwise it may affect the fertilization effect.
