[0029] As Figure 2As shown, further, the rotating hammer mechanism 6 comprises a rotating main shaft 61, support discs 62, a connecting shaft 63, a swing arm 64 and a hammer head 65. The rotating main shaft 61 is arranged horizontally in the grinding bin 4 and is connected with the rotating driving mechanism 5. A plurality of the support discs 62 are equidistantly arranged along the extension direction of the rotating main shaft 61 and are fixedly connected with each other through the connecting shaft 63. One end of the swing arm 64 is sleeved with the connecting shaft 63, and the other end of the swing arm 64 is connected with the hammer head 65. The hammer head 65 is in a spherical structure and is used for impacting and grinding the rice along with the rotation of the rotating main shaft 61. The plurality of support discs 62 are equidistantly arranged along the extension direction of the rotating main shaft 61 and are fixedly connected with each other through the connecting shaft 63.
