[0002] With the large-scale development of facility agriculture, greenhouse planting has become the core way to ensure the stable supply of winter vegetables, fruits and other crops. At present, the snow removal of greenhouse heat preservation film is mostly carried out by spraying water and air gun for cleaning, which is easy to cause snow accumulation at the lower end of the greenhouse. These two methods cannot completely remove the accumulated snow to the designated area, but instead, the accumulated snow will be washed or blown to the lower end of the greenhouse (the ground around the greenhouse). After the snow accumulates at the lower end of the greenhouse, additional manpower and material resources are needed for secondary cleaning, which not only increases the operation cost and labor intensity, but also may cause the deterioration of the environment around the greenhouse due to long-term accumulation of snow, such as ground icing, excessive soil humidity affecting vegetable growth, etc. SUMMARY
