Design and test of the device forming grass-braid driven by diesel or electricity

Abstract. The forming device is mainly includes the frame, shaping drum, pulling grass roller and driven roller part. The machine described in this article is mainly used for processing grass into the shape of braid. According to the working principle of the whole machine, the grass plate in two shaping drum provides the grass a rotation movement relative to two rollers. Then, the braided grass is formed by two surge of rotating grass which gathered in the middle of two grass roller. This device is suitable for the braid of alfalfa, elymus, black wheat, etc. which length is 500 mm above. The productivity is 500 kg/h and the braid diameter is 120 mm. This proposed method could meet the requirement of real-time forage processing in Qinghai-Tibet Plateau. The grass braid is convenient to transport and storage.
