Abstract:
1. A grain milling machine comprising: a main shaft that is perpendicularly and rotatably supported to a body base; a cylindrical integral grain milling roll body that is formed in a cylindrical shape in the vertical direction by disposing a plurality of annular grain milling rolls in multiple stages; a cylindrical bran removing metallic mesh cylinder; a cylindrical bran removing cover; and a bran discharge pipe, wherein the grain milling roll body is attached to the main shaft so as to rotate together with the main shaft, the bran removing metallic mesh is disposed outside the grain milling roll body to be fixed to the body base and forms a grain milling chamber between the bran removing metallic mesh and the grain milling roll body, the bran removing cover is disposed outside the bran removing metallic mesh to be fixed to the body base and forms a bran removing chamber between the bran removing cover and the bran removing metallic mesh, the bran discharge pipe is disposed so as to communicate with the lower portion of the bran removing chamber, a motor rotationally driving the main shaft is disposed below the main shaft while being supported to a motor base, a fan-pulley is attached to the communication portion between the bran removing chamber and the bran discharge pipe in the main shaft, the fan-pulley having a function of rotationally driving the main shaft and a function of generating a bran removing wind for conveying bran produced by the grain milling action of the grain milling roll body from the bran removing chamber toward the bran discharge pipe, a conveying belt is wound between a motor pulley of the motor and the fan-pulley attached to the main shaft, and a moving device which adjusts a distance between the shafts of the motor pulley and the fan-pulley by moving the motor base relative to the body base portion in the horizontal direction is provided.
