At this time, with the help of the anti-slip pad 101, the stability of the device can be ensured. When screening the material, first place the collecting bottle 5 just below the discharge port at the lower end of the screening bucket 4. With the sliding action between the sliding block 301 and the vertical rod 2, the height of the screening bucket 4 can be adjusted until the sealing pad 401 contacts the upper end surface of the collecting bottle 5 to achieve sealing. Then, the sliding block 301 and the vertical rod 2 are locked by bolts.
