PURPOSE:To extract a small quantity of powder material from the dropping powder material mechanically, automatically and continuously providing a rotatable bucket for extracting a sample dropping a passage wherein conveyed powder material such as ammonium chloride sodium bicarbonate, or the like. CONSTITUTION:The sample extracting bucket 5 is joined with the half-rotatable driving axis 3 through the arm 4, it is turned by the rotation a of the axis 3 and is located in the powder material passage 2 which is formed between the upper shoot 1a and the lower shoot 1b to extract the dropping powder material. Next the extracted material in the bucket 5 is dropped or dipped together with the bucket in the dipping liquid 6 in the dipping tank 8 to throw itself into the dipping liquid 6. When the powder material is completely dissolved or mixed in the dipping liquid 6, the solution is taken from the feed pipe to provide itself for the measurement and analysis The powder material can be extracted mechanically, automatically and continuously by combining the rotation of the axis 3 with an electrically controlled device that consists of a relay and a timer.
