detailed description

The specific embodiment of the utility model will be described in further detail below with reference to the accompanying drawings.

The engine radiator dust removal device shown in Figure 1, 2, 3 and 4 comprises the wind cover device 5 that is installed on the outside of wind guide cover 11, and wind guide cover 11 is installed on radiator assembly 10 air inlet sides, and wind cover The outer side of the device 5 is fixed with a guard plate 2, and a through hole is provided in the middle of the wind shield device 5 and the guard plate 2, and a mounting plate 6 is arranged at the through hole of the wind shield device 5, and the outer side of the mounting plate 6 is connected with a shaft through a rotating shaft 3. The flow fan 4 is fixed with a cyclone cover 1 at the other end of the rotating shaft 3, and the cyclone cover 1 passes through the through hole on the guard plate 2, and the end surface and the side of the cyclone cover 1 are provided with ventilation filter holes.

There is a rotating plate 8 on the outer periphery of the inner end of the cyclone hood 1, and the rotating plate 8 is distributed with spiral teeth along the circumferential direction. When the cyclone hood 1 rotates, the spiral teeth generate tangential wind along the circumferential direction, thereby avoiding impurities such as dust and broken stems. Enter the radiator from the gap between the cyclone cover 1 and the wind cover device 5 to block the core.
