The application of fog cannon machines in greenhouse snow removal involves using the fan to generate strong air flow, which, combined with specific nozzles, atomizes a small amount of water and sprays it at high speed. The impact force of the air flow blows off the snow on the greenhouse surface. With flexible range and wide coverage, it can adjust the spray angle according to the height and width of the greenhouse, avoiding trampling damage from manual snow removal and collision risks from mechanical operations. Easy to operate, supporting remote or manual adjustment, it can quickly clear snow from large-area greenhouses, reducing the risk of greenhouses collapsing under snow load. It is especially suitable for winter snow removal in small and medium-sized greenhouses, ensuring the safety of crops and the stability of facilities inside the greenhouses.
