description In order to study the mechanism of bract peeling and crushing of a corn harvester, a bract stripping and crushing device was designed that mainly consists of a stripping device, a crushing device, and a frame. The kinematics and dynamics of the roller of bract stripping device were analyzed, and the conditions of bract stripping were obtained. Single factor tests of stripping roller speed and crushing roller speed were carried out. On the basis of single factor tests, orthogonal experiments were carried out to determine crushing roller speed, distance between crushing device axis and stripping device axis, stripping roller speed, and offset angle of stripping roller. The orthogonal experiments showed that the optimum parameters of the device were obtained: the speed of the crushing drum was 1,100 r/min, the axis distance between the stripping and crushing devices was 180 mm, the speed of the stripping roller was 400 r/min, and the offset angle of the stripping roller was 5 degrees. On the basis of orthogonal experiment, three, five, seven, nine and eleven corn feeding and high-speed photography experiments were carried out respectively. The results showed that when three ears of corn were fed at the same time, the effect of corn bract stripping and crushing was the best with the increase of corn number. The stripping roller only grasps most of the bracts of corn at 0.019 s, after stripping the bracts into the crushing device, the bracts were crushed after 0.077 s. The crushing time of bracts was approximately four times as long as that of the bracts.
