The larger stones in the wastewater are blocked by the coarse filter screen 7.

There is no need to pull out the coarse filter screen 7 and move it to the collection container for dumping.

The larger stones in the wastewater are blocked by the coarse filter screen 7. When there are too many stones on the coarse filter screen 7, the cylinder 11 moves upward, driving the linkage column 12 connected to its top to move upward together. Since the linkage column 12 penetrates the linkage grooves 15 in the two linkage rods 14 at one time, the right linkage rod 14 rotates clockwise and the left linkage rod 14 rotates counterclockwise, so that the two baffles 3 and the two L-shaped plates 5 rotate in opposite directions.
