The screen assembly 2 is inclined and its top and bottom sides are movably connected to the support 1. The first drive assembly 3 is used to drive the top of the screen assembly 2 to move, thereby changing the inclination angle of the screen assembly 2. The second drive assembly 4 is used to drive the bottom of the screen assembly 2 to move, thereby changing the inclination angle of the screen assembly 2. Specifically, the second drive assembly 4 and the first drive assembly 3 do not work simultaneously. When the second drive assembly 4 and the first drive assembly 3 do not work simultaneously, the inclination angle of the screen assembly 2 can be changed, such as increasing the inclination angle to make the tobacco fall more smoothly.
