The invention discloses a novel safety surface aeration machine, which comprises a rotation shaft (1), wherein an inverted-umbrella-shaped blade wheel (2) is arranged under the rotation shaft (1), a controller (3) is arranged on the rotation shaft (1), and is provided with a lifting device (4), a speed reducer (5) is arranged beside the lifting device (4), a three-phase asynchronous motor (7) is connected through a coupling (6), a thermometer (8) is arranged beside the rotation shaft (1), and an alarm device (9) is arranged beside the thermometer (8). According to the present invention, the novel safety surface aeration machine has characteristics of reasonable design and simple structure simple, and can achieve the expected effect during the working; most of the rotation shafts have the requirements on high-temperature resistance, such that the material of the novel safety surface aeration machine can meet the requirement; and the rotation shaft is made of the reinforced composite material so as to reinforce and improve the use safety.
