In particular, the cyclone separator is rotatably arranged on the cyclone bracket, and the cyclone separator can be driven to rotate between two positions, a material receiving state and a non-material receiving state, by a rotating power mechanism. When it is in the material receiving state, the inlet of the feed pipe of the cyclone separator is aligned with the discharge port at the lower end of the grinding mechanism. When it is in the non-material receiving state, it is rotated away from the position below the discharge port at the lower end of the grinding mechanism.

Furthermore, the transport bottle mechanism described in the utility model realizes the transport of sample bottles by providing a translation module and a bottle clamping mechanism. In particular, the tail ends of the left bottle clamping rod and the right bottle clamping rod of the bottle clamping mechanism for clamping the sample bottle have a left disc part and a right disc part with gear teeth meshing with each other, and the left bottle clamping rod is driven to rotate around the center of the left disc part by a reciprocating driving mechanism, and the opening and closing of the left bottle clamping rod and the right bottle clamping rod are realized by the meshing of the gear teeth on the left disc part and the right disc part.
