The stirring motor 21 is fixedly connected with the machine shell 1 and is arranged outside the machine shell 1. The stirring head 22 is arranged in the first cavity 11 and can be driven by the stirring motor 21 to rotate, so that the ore powder in the first cavity 11 is uniformly stirred.

The platen 3 includes a platen upper plate 31, a platen lower plate 32, and a first rotating motor 33. The upper platen plate 31 is provided with a through hole 311, the through hole 311 faces the lower end of the conveying part 12, and the lower platen plate 32 is smaller than the upper platen plate 31 but larger than the through hole 311. The upper surface of the lower platen plate 32 abuts against the lower surface of the upper platen plate 31 and is rotatably connected to the upper platen plate 31, and the rotating shaft is located at an eccentric position of the lower platen plate 32. The first rotating motor 33 is in transmission connection with the lower platen plate 32 and can drive the lower platen plate 32 to rotate, and the passing opening 311 is intermittently covered in the rotating process.

In this embodiment, since the first rotating motor 33 is preferably disposed outside the second chamber 13, it is then in transmission connection with the lower platen plate 32 inside the second chamber 13 through the machine case 1 via a transmission structure such as a belt, a gear, etc. Since the platen lower plate 32 is controlled to cover the through-opening 311 by controlling the first rotating motor 33, it is necessary to obtain a high control accuracy. In the present embodiment, therefore, the first rotating motor 33 employs a stepping motor.

In use, the mineral powder is added into the first chamber 11 through the feed inlet and then mixed for the first time under the stirring action of the stirring device 2. Passes through the conveying portion under the action of gravity and falls onto the platen upper plate 31. At this time, the platen lower plate 32 is located directly below the passage opening 311, and the ore powder is accumulated on the platen upper plate 31. The first rotating motor 33 is then controlled to rotate, which rotates the lower platen plate 32, so that the ore powder can fall through the through-hole 311 onto the upper sorting plate 41. The platen lower plate 32 is rotated back to just below the through-port 311 after a rated time, and the through-port 311 is closed, thereby controlling the amount of mineral powder falling onto the sorting upper plate 41. The lifting device 5 drives the press plate 3 to move downwards, so that the mineral powder on the sorting upper plate 41 is compacted and then returns to the original position. Then the second rotating motor 43 rotates the sorting lower plate 42 to a certain angle, so that the first sorting hole 411 and the second sorting hole 421 coincide, the mineral powder can fall through the first sorting hole 411 and the second sorting hole 421 and slide down from the discharge port 14 to the weight detector 6, so that the obtained sample is already of the required size, and the quality of the sample can be detected by the weight detector 6.
