Abstract: Aiming at the problem of clogging that often occurs in the traditional small straw round baler baling operation, this paper combines the requirements of the baling and designs a new type consisting of a front feeding pair roller, a rear squeezing pair roller, and a guard plate. Using rice stalks as the experimental material, the feeding mechanism adopts a 3factor 5horizontal orthogonal rotation design method for experimental research and analyzes the distance between the front feeding pair rollers and the rear squeezing pair rollers, and the squeeze inclination angle pair. The experiment shows that the current feeding pair roller spacing is 50 mm, the rear extrusion pair roller spacing is 22 mm, and the extrusion inclination angle is 19°. The feeding mechanism can effectively reduce the problem of blockage of small straw round baler. The mechanism appears to meet the daily bundling demand. This research can provide a reference for the structural design of the round baler.
