[0023] The docking block 13 is inserted into the docking groove 11, the inner wall of the movable frame 12 is fitted with the outer wall of the fixed frame 10, and the outer edge of the movable frame 12 is connected with a connecting block 15; a threaded rod 16 passes through the middle of the connecting block 15, and the threaded rod 16 is connected to the inner wall of the screening machine body 1 through a bearing seat; a motor 17 is installed on the surface of the screening machine body 1, and the output end of the motor 17 passes through the screening machine body 1 and is connected to the threaded rod 16, and the threaded rod 16 and the connecting block 15 are threadedly connected, the docking blocks 13 are symmetrically distributed about the center line of the movable frame 12, and the dividing frame 14 is symmetrically distributed about the center line of the movable frame 12.
[0024] During the specific implementation, the starting motor 17 drives the threaded rod 16 connected to the output end to rotate synchronously. Since the threaded rod 16 and the connecting block 15 are threadedly connected, as the threaded rod 16 rotates, the connecting block 15 can be driven to move downward, and the downwardly moving connecting block 15 drives the connected movable frame 12 and the dividing frame 14 to move downward synchronously, and the movable frame 12 moves steadily downward along the docking grooves 11 on the fixed frame 10 during the downward movement, until the movable frame 12 is moved down to the limit position. At this time, the movable frame 12 and the dividing frame 14 pass through the through groove 8 at the top of the sieve bin 4. After the flour to be screened is added from the feeding hopper 9, it falls from the dividing frames 14 on both sides through the fixed frame 10 and the movable frame 12 to the sieve plate 5 for screening. The two inclined dividing frames 14 set at the bottom of the movable frame 12 can distribute the flour to be screened to both sides, making the screening more uniform, thereby making the high square sieve convenient for uniform material distribution.

[0026] During the specific implementation, the limit pin 21 is first pushed upward, and the limit block 22 connected to the inner wall of the limit pin 21 moves synchronously with the movement of the limit pin 21. The pushed limit pin 21 moves along the guide rod 23 and squeezes the spring 24 sleeved on the outer side of the guide rod 23 until the limit pin 21 is pushed to the limit position. At this time, the limit block 22 and the limit groove 20 are separated. At this time, the connecting plate 19 can be pulled outward to drive the sieve plate 5 to be pulled, and the sieve plate 5 can be disassembled and cleaned.
