The utility model provides a pressure adjusting device for a rice outlet of a rice mill, which comprises a rear plate, a front plate, a support, a rotating shaft, an adjusting seat, an adjusting cavity, a front ejector head, a rear ejector head and a spring, and the variable pitch type spring is arranged in the adjusting cavity to meet the pressure adjustment of different types of rice materials, the pitch size of the spring located at the two ends is smaller than that of the spring located in the middle, and therefore in the process that the rotating shaft drives the adjusting base to move so as to drive the front ejection head to compress the spring, the spring located at the two ends is compressed firstly and acts on the rear plate through the rear ejection head. When the variable-pitch spring is compressed, the generated elastic force is small so as to meet the requirement for grinding long-grain rice, when the spring is further compressed, the middle area with the large pitch is pressed, large elastic fo
