[0030] Specific usage method and function of this embodiment:
[0031] In the present utility model, when adjusting the size of the mesh holes formed by the square holes of the fixed screening plate 3 and the movable screening plate 5, the screening plate adjusting rod 4 is rotated forward with tools and thread-engaged with the screening bearing box 2, so that the screening plate adjusting rod 4 moves leftward through thread engagement, and the screening plate adjusting rod 4 drives the movable screening plate 5 to move leftward synchronously through bearings. Thus, the overlapping degree of the square holes of the fixed screening plate 3 and the movable screening plate 5 increases, and the mesh holes formed by the square holes of the fixed screening plate 3 and the movable screening plate 5 become larger until the square holes of the fixed screening plate 3 and the movable screening plate 5 completely overlap, and the state is as shown in Figure 5As shown in the figure, by reversely rotating the sieve plate adjusting rod 4 with a tool, the sieve plate adjusting rod 4 is threadedly engaged with the screening carrier box 2. The sieve plate adjusting rod 4 moves to the right through threaded engagement, and the sieve plate adjusting rod 4 drives the movable screening plate 5 to move synchronously to the right through a bearing. Thus, the degree of coincidence of the square holes of the fixed screening plate 3 and the movable screening plate 5 is reduced, and the mesh holes formed by the square holes of the fixed screening plate 3 and the movable screening plate 5 become smaller. Thus, the adjustment of the size of the screening mesh holes is realized; when the inclination angle of the screening carrier box 2 is adjusted, by forwardly rotating the angle adjusting rod 7 with a tool, the angle adjusting rod 7 is threadedly engaged with the adjusting movable block 8, and the adjusting movable block 8 moves to the left through threaded engagement. The right end of the inclined support plate 9 is driven by the adjusting movable block 8 to move synchronously to the left, and the left end of the inclined support plate 9 is turned upward. The left end of the inclined support plate 9 pushes the left side of the screening carrier box 2 upward, causing the left side of the screening carrier box 2 to turn upward. Thus, the inclination angle of the screening carrier box 2 becomes smaller. By reversely rotating the angle adjusting rod 7 with a tool, the angle adjusting rod 7 is threadedly engaged with the adjusting movable block 8, and the adjusting movable block 8 moves to the right through threaded engagement. The right end of the inclined support plate 9 is driven by the adjusting movable block 8 to move synchronously to the right, and the left end of the inclined support plate 9 is turned downward. The left end of the inclined support plate 9 drives the left side of the screening carrier box 2 to turn downward. Thus, the inclination angle of the screening carrier box 2 becomes larger. Thus, the adjustment of the inclination angle size of the screening carrier box 2 is realized.
[0032] Embodiment 2:
[0033] The difference from Embodiment 1 is that the regular hexagonal prism of the sieve plate adjusting rod 4 can also be set as a regular heptagonal prism. Thus, the sieve plate adjusting rod 4 needs to be rotated by a special tool that cooperates with the regular heptagonal prism, preventing non-staff from rotating and adjusting the sieve plate adjusting rod 4.
[0034] Embodiment 3:
[0035] The difference from Embodiment 1 is that the regular hexagonal prism of the angle adjusting rod 7 can also be set as a regular heptagonal prism. Thus, the angle adjusting rod 7 needs to be rotated by a special tool that cooperates with the regular heptagonal prism, preventing non-staff from rotating and adjusting the angle adjusting rod 7.
