Greenhouse snow is also receiving increasing attention in northern China during the winter. In winter, the top snow cover of greenhouse seriously affects light intensity and heat insulation, and is harmful to the growth of flowering plants, and affects the overall strength and stiffness of greenhouse. There are potential safety problems. Thus, it causes serious economic losses to farmers. At present, snow removal in Chinas greenhouse is mainly divided into manual snow removal method, snow melting method and mechanical snow removal method, but each has its advantages and disadvantages. By studying the advantages and disadvantages of snow removal equipment in the past, combined with the development trend of snow removal in our country, a greenhouse snow removal device was developed. It is simple, compact, low cost and automatic. The device comprises a frame, a moving vehicle, a snow blower and a cam rotor mechanism. Horizontal mobile snow blower to move the car, make sure the temperature indoor snow can be blown into the air blowing m
