[0019] The second rotating shaft 6 is located on the right side of the first rotating shaft 5. The first cam 15 and the second cam 16 are coaxially fixed to the second rotating shaft 6. The first cam 15 contacts the first filter screen 10, and the second cam 16 contacts the second filter screen 11.
