As a further scheme of the invention: the movable block is arc-shaped, and the surface of the movable block close to the annular groove is the same as the inner wall of the annular groove in shape.

As a further scheme of the invention: the connecting rod and the fixing rod are perpendicular to each other.

As a further scheme of the invention: the upper surface of the nut is provided with a manual rotating handle.

As a still further scheme of the invention: the upper surface of connecting rod is provided with dials the tooth, dials the quantity of tooth and is two sets of, and two sets of tooth use the vertical axis of vertical pole as the axisymmetric setting of dialling.

Compared with the prior art, the invention has the beneficial effects that: through setting up the ring channel, lower hopper, the movable block, mutually support between connecting rod and the spiral leaf, directly empty raw and other materials go into down the inside of hopper can, need not manual pouring a bit, the inside of movable block ring channel slides, the dead lever drives the spiral leaf through rotating when the filter screen is rotatory and rotates, make down the inside raw and other materials of hopper evenly fall on the filter screen, the effect of the inside automatic even whereabouts of raw and other materials of hopper has reached down, need the continuous raw and other materials of pouring of staff when having solved the screening, staff's intensity of labour has been increased, lead to the lower problem of work efficiency.
