The second drive component and the third drive component have the same driving principle, thereby achieving multi-dimensional adjustment of the fixed plate (25), which is convenient for adjusting the level as needed. Step 3: The electric push rod (35) of the support lifting assembly of the material distribution support assembly (3) drives the side plate (37) to move. Under the action of the guide rail (311) and the slider (313), the side plate (37) moves horizontally. The side plate (37) drives the push column (38) to move. The push column (38) and the first inclined groove (310) work together to drive the straight plate (39) to move. The straight plate (39) drives the horizontal plate (36) to move.

Step 5: The electric push rod (35) supporting the lifting assembly drives the side plate (37) to move. Under the action of the guide rail (311) and the slider (313), the side plate (37) moves horizontally. The side plate (37) drives the push column (38) to move from the first inclined groove (310) to the second inclined groove (312). When the push column (38) moves to the bottom of the first inclined groove (310), the straight plate (39) drives the horizontal plate (36) to move.
