In order to improve the efficiency of straw fiber preparation, solve the problems of the artificial labor intensity and the discontinuous feeding process in the feed process. A vertical downward spiral forced feeding device was designed. Based on the analysis of the structure and working principle of the feeding device, the straw length, rotating speed of screw and water content were supposed to be the main influence factors. Transport efficiency were chosen as the evaluating indicator. Experimental investigations were carried out with the method of quadratic orthogonal rotation combination design to obtain the optimal parameter combination. The results showed that:(1) The order of the influence extent on transport efficiency of soybean straw is the length of the straw, the rotating speed of the screw shaft, water content of the straw.(2) The optimal combination of parameters occurred with that the straw length was 60-120 mm, the rotating speed of screw is 160 r·min-1, the water content was 78%-90%, meet the requirements of feeding efficiency of 1000 kg · h-1for fiber preparation machine. This research provides a reference for the design of forced feeding device.
