The material inside the sampling tube 1 can be lifted by the spiral conveying rod 8, and then enters the interior of the connecting bucket 2. The electric push rod 10 is started, and the blocking frame 5 is driven by the electric push rod 10 to rotate along the rotating shaft 12, so that the bottom of the connecting bucket 2 is exposed, so that the material can be discharged. At the same time, the very small amount of powder adhered to the sampling tube 1 during the last sampling is completely removed and discharged to prevent sample mixing. When the sampling head 6 reaches the designated point, it stops descending and the spiral conveying rod 8 stops rotating.
