Most of these crops are grown in greenhouses. However, in winter, whether crops are grown in greenhouses or in farmland, frost disasters may occur. Therefore, anti-frost equipment is gradually popularized in the Chinese market, and the demand for anti-frost machines is gradually increasing.

[0003] Small anti-frost machines are generally driven by motors due to their small blade diameter and short anti-frost distance. However, the blade diameter of large anti-frost machines can reach 6 meters, which requires the blade shaft to transmit a larger torque. General motors cannot meet this requirement, and the function also requires a motor to realize the revolution function. Therefore, large anti-frost machines use a reduction gear transmission structure. This structure uses bevel gear transmission to realize the blade rotation, and at the same time adds two sets of worm gear mechanisms to realize the reduction gear revolution, so that the blades of large anti-frost machines can both rotate and revolve slowly.
