In the process of grinding and sample preparation, the final collection of samples is a very important link. On the one hand, it is required to avoid material pollution of the environment during the collection process, and on the other hand, the loss rate is required to be as low as possible. At present, the grinding devices on the market collect materials in a direct way, that is, the sample bottle is placed directly at the outlet of the grinder. During the grinding process, the sample that meets the particle size requirements falls directly into the sample bottle through the sieve hole at the bottom of the grinder. The problem with this direct material collection method is that there is serious residue in the grinding chamber, which is easy to mix with the next batch of samples. At the same time, the loss rate is high and causes environmental pollution.

Through this solution, the cyclone separator can also be raised and lowered, and it can drive the bottle placing component 2 to rise through the lifting power device 3 so that the sample bottle on it docks with the outlet of the cyclone separator 11, and further rise, which can push the cyclone separator 11 to rise. When descending, as the bottle placing component 2 descends, the cyclone separator 11 can automatically fall. When the cyclone separator 11 descends, the feed hopper 12 of the cyclone separator 11 can be separated from the discharge port of the grinding equipment.
[0030] In order to allow the sample bottle to be separated from the outlet of the cyclone separator 11, a stopper 15 for stopping the cyclone separation assembly 1 from descending is fixed on the mounting bracket 4.

When the cyclone separator 11 stops descending due to the stopper, the bottle placing assembly 2 is further descended, so that the sample bottle on the bottle placing assembly 2 is separated from the outlet of the cyclone separator 11, so that the sample bottle can be taken out. When the material receiving is stopped, the rotating power mechanism 16 can drive the cyclone separator 11 to rotate, so that the feed hopper 12 of the cyclone separator 11 is separated from the lower end outlet of the grinding device 100, and the grinding device can be cleaned.
