According to the reality that all-harvest cotton picker had a high impurity rate, and with the reference of Handan cotton picker and Tian'e cotton picker, that they have optimized the nailed roller to 12-prism structure with mechanical riveted taper spherical crown type nails from cylindrical roller, this paper puts forward a research method to apply to separate impurities from the cotton in the separating system of the machinery 6-prism roller; it contains the composition of the main components, working principle and its design.The main components in the separating system of the device are the 3-dimensional entity models and theoretical assembly drawings with the software of Pro/Engineer. The machinery separating method combines the 6-prism barbed nail roller and riffle grid, and can remove the mixed soils, tiny stones, broken cotton leaves, mote, and other big sundries (green peaches, cotton stalk, fluid shell and broken plate,
etc.). It improves the quality of the machine-picked cotton, and reduce cotton fiber damages. |
