[0025] The above scheme is adopted: the threaded rod 51 is driven to rotate by the motor 3, thereby driving the support block 52 screwed on the side to move downward along the slide 13, and the screen mechanism 6 rotates downward along the support block 52 due to the weight of the stones above, and then the stones will slide down, thereby distinguishing the delivery of fine aggregates and stones.
