The inclination angle of the soft baffle 12 can also be adjusted by manually turning the adjustment rod 1, thereby controlling the gap between the soft baffle 12 and the screen surface 16, thereby controlling the flow of the coal slime. The device has a simple structure and achieves cost reduction and efficiency improvement.
[0026] Furthermore, the soft baffle 12 is made of rubber. The width of the soft baffle 12 is equivalent to the width of the screen surface 16, so that the soft baffle 12 can block all the coal slime falling onto the curved screen.
[0027] Furthermore, the adjusting rod 1 and the supporting rod 3 are perpendicular to each other.
[0028] In some embodiments, the two ends of the support rod 3 are installed on both sides of the screen side 15 of the curved screen through an adjustment bracket. By setting the adjustment bracket, curved screens of various sizes can be satisfied.
