[0029] A fixed millstone 1 and a rotating millstone 2 are provided on the inner side of the upper part of the casing 3, and an annular gap is provided between the circumference of the fixed millstone 1 and the inner wall of the casing 3; a plurality of support rods 102 are evenly connected on the circumference between the lower part of the fixed millstone 1 and the inner wall of the casing 3; the support rods 102 surrounding the fixed millstone 1 enable the fixed millstone 1 to be firmly fixed and able to withstand greater pressure.

[0030] The upper part of the fixed millstone 1 is a tapered portion 101 that gradually descends from the center to the surroundings; the rotating millstone 2 is located on the upper side of the fixed millstone 1; the upper and lower parts of the rotating millstone 2 are respectively provided with corresponding vertical holes 201 and tapered holes 202, the vertical holes 201 are connected to the upper ends of the tapered holes 202, and a through hole is formed on the rotating millstone 2.

[0031] Two rotating supports 5 for supporting the rotation of the rotating grinding disc 2 are provided between the inner wall of the casing 3 and the rotating grinding disc 2; the two rotating supports 5 are respectively located on the outer side of the upper and lower parts of the rotating grinding disc 2; the rotating supports 5 include an annular groove and an annular protrusion, the annular groove is fixed to the inner wall of the casing 3, and the annular protrusion is located on the outer side of the rotating grinding disc 2 and rotates along the annular groove.

[0032] In this embodiment, the rotating milling disc 2 is driven to rotate by the driving assembly 6. The driving assembly 6 includes a ring gear 601, a gear set 602, a reduction motor 603 and a gear box 604; the gear box 604 is connected to one side of the housing 3 and communicated with the inner side of the housing 3; the ring gear 601 is arranged around the outer side of the middle of the rotating milling disc 2, the gear set 602 is rotatably installed in the gear box 604 and meshes with the ring gear 601, and the reduction motor 603 is installed on the upper side of the gear box 604, and its output shaft extends into the gear box 604 and is connected to the gear set 602 to drive the gear set 602 to operate. In this embodiment, the gear set 602 includes two meshing gears, one gear meshes with the ring gear 601, and the other gear is connected to the reduction motor 603.

[0033] The reduction motor 603 drives the gear set 602 in the gear box 604 to operate, and the operation of the gear set 602 causes the ring gear 601 and the rotating grinding disc 2 to rotate under the support of the rotating support 5.

[0035] The gap between the inner wall of the conical hole 202 and the conical portion 101 gradually decreases from top to bottom; the rotating grinding disc 2 rotates to crush the peanut kernels entering between the inner wall of the conical hole 202 and the conical portion 101. The rotation of the rotating grinding disc 2 crushes the peanut kernels and promotes the peanut kernels to scatter downward, and are discharged from the annular gap between the rotating grinding disc 2 and the lower edge of the fixed grinding disc 1, pass through the gap between the support rods 102, and fall on the lower part of the casing 3.

[0036] A scraper 4 is provided at the lower side of the outer edge of the rotating grinding disc 2 to scrape off the crushed material on the upper side of the support rod 102. In this embodiment, the scraper 4 is a rubber plate, which moves on the upper side of the support rod 102. The crushed peanuts falling on the upper side of the support rod 102 are scraped off by the scraper 4 and fall on the lower part of the housing 3, thereby avoiding the accumulation of crushed materials. One to four scrapers 4 can be provided, which are evenly distributed on the lower side of the edge of the rotating grinding disc 2. In some other embodiments, a brush can be used instead of the scraper 4.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the utility model and is not intended to limit the utility model.
