[0021] The utility model will be further described below in connection with the drawings:

[0022] As Figure 1 , Figure 2 shown, the utility model discloses rack (1), the rack (1) is fixed with the mill white room (2), the rack (1) one side is equipped with drive motor (3), the upper portion of rack (1) is equipped with upper suction hood (4) and feeding device (5), the lower portion of mill white room (2) is equipped with bran chaff separation hopper (15), it is characterized by: the mill white room (2) is equipped with integral screen frame (6) in, as Figure 6 , Figure 7 shown, the integral screen frame (6) includes lower support seat (16) and upper fixed seat (17), and lower support seat (16) is fixed with left rotary arm frame (19) and right rotary arm frame (20) through rotary hinge shaft (18), and left rotary arm frame (19) and right rotary arm frame (20) are fixed with first integral screen frame (23) and second integral screen frame (24) through left rotary hinge shaft (21) and right rotary hinge shaft (22) respectively, and first integral screen frame (23) and second integral screen frame (24) are all provided with screen. As Figure 4 , Figure 5 shown, the bran chaff separation hopper (15) is equipped with upper inlet (7) and lower inlet (8), and the upper inlet (7) and lower inlet (8) are equipped with upper inlet air register (9) and lower inlet air register (10) respectively, and the inside of bran chaff separation hopper (15) of upper inlet (7) and lower inlet (8) is equipped with upper chaff baffle (11) and lower chaff baffle (12) respectively.
