Multifunctional rice polishing machine

The utility model relates to the technical field of rice polishing machines, in particular to a multifunctional rice polishing machine which comprises a barrel body, a rotating shaft is inserted in the barrel body, a motor drives the rotating shaft to rotate, the rotating shaft is sequentially sleeved with a head friction ring, a plurality of slope rings and a tail friction ring, and the slope rings enable friction gaps to be gradually reduced. The top of the barrel body is communicated with a feeding hopper located above the first friction ring, a discharging hole is formed in the bottom of the barrel body, a sliding rail is fixedly installed on the barrel body, and a baffle wrapping the discharging hole is inserted into the sliding rail in a sliding mode. The friction gap of agricultural products in the barrel body is adjusted through the head friction ring, the tail friction ring and the slope ring, and the gap is gradually reduced from the head friction ring to the tail friction ring, so that the agricult
