[0018] 3. In addition, after the detection experiment is completed, push the annular fixed plate downward so that the locking pin exits the locking socket, so that the movable box sleeve can be in an active state, and slowly move the movable box sleeve downward to reset it, driving the pushing and concentrating plates to move toward each other, so that under the action of the pushing and concentrating plates, the sediment on the bottom surface of the base box can be pushed and concentrated to the falling through hole, and at the same time, with the reverse rotation of the rotating disk body, the closed movable plate will also be driven to move in the opposite direction and separate, so that the sediment can fall onto the receiving plate for discharge, and at the same time, under the action of the pushing ramp, the sediment accumulated on the closed movable plate can be pushed down.
