The detailed connection means are well-known technologies in the field. The following mainly introduces the working principle and process.

[0036] Embodiment: When in use, the user can rotate the screw 9 as needed, so that the adjusting plate 8 drives the rotating rod 7 and the moving grinding disc 3 to move up and down, and the distance between the static grinding disc 2 and the moving grinding disc 3 is adjusted to meet the grinding requirements of different finenesses. The buckwheat grains to be ground are poured into the feed hopper 16 located above the center of the static grinding disc 2. The motor 10 rotates the rotating drum 6 through the meshing action of the main gear 11 and the sub-gear 12, and the rotating rod 7 inside the rotating drum 6 also rotates. The spiral blades 13 at the bottom of the rotating rod 7 pull the buckwheat grains from the feed hopper 16 into the rotating drum 6. The channel 4 is transported downward to between the moving grinding disc 3 and the static grinding disc 2, and the transported buckwheat grains enter the narrow space between the static grinding disc 2 and the moving grinding disc 3. Since both discs are conical structures, a gradually tightening grinding chamber is formed from top to bottom. As the rotating rod 7 continues to rotate, the buckwheat grains are squeezed and sheared between the two discs and are gradually crushed into powder. The ground buckwheat powder is discharged through the discharge port 14 at the bottom of the shell 1 under the action of gravity. A pair of guide plates 15 located on both sides above the discharge port 14 help to guide the material to flow out smoothly and reduce blockage.
