The first motor 13 is operated to adjust the positions of the arc scraper 16 and the crushing roller 24, so as to reduce the thickness of the frost ice. When the thickness of the frost ice is thick, the first motor 13 works in a complex manner to reduce the occurrence of jamming. The thicker frost ice can be removed by multiple rotations. When in use, the staff can adjust the tightness of the first spring 32 by rotating the screw 42, so as to facilitate the staff to adjust the force of the arc scraper 16 when it needs to avoid according to the equipment conditions. If the first spring 32 is too loose, it will affect the removal of frost ice by the arc scraper 16. When in use, the rotation of the square rod 23 will drive the push seat 51 to move, and the rotation of the fixed seat 52 will drive the ball 55 The ball 55 rotates, and during the movement, the spherical block 54 pushes the fixed seat 52 and the crushing roller 24 downward. The downward movement of the crushing roller 24 can pull the frozen frost to be broken and peeled off, thereby improving the crushing effect.
