Batch mixing instrument for solid powdery experimental samples

The utility model discloses a batch mixer for solid powder experimental samples, which comprises a base, the top of the base is provided with a placement groove, the placement groove is of a cylindrical structure, the center of the bottom of the placement groove is rotatably provided with a limiting block, and the center of the top of the limiting block is welded with a positioning shaft. According to the batch mixing instrument for the solid powdery experimental samples, the placing block provided with multiple groups of placing holes is matched with the motor for use, so that the batch mixing instrument can uniformly mix multiple groups of solid powdery experimental samples at one time, and compared with manual one-by-one operation, the batch mixing instrument greatly improves the mixing efficiency of the solid powdery experimental samples; meanwhile, the labor intensity of workers is reduced to a certain extent, meanwhile, the device adopts a baffle to seal a placement hole, the situation that a solid powd
