【Abstract】 The disc branch chipper with short knives is a new type of branch chippers, and a patent has been obtained in China. This new chipper is used to make technological wood chips suitable for paper pulp, fiber board, particle board, and also make mulch suitable for beds, borders in public parks, play areas, paths etc. This paper mainly studies the design parameters of disc branch chipper with short knives, analyzes the factors affecting the design parameters, especially the cutting force per unit of knife length and cutting power. By experiment of dynamic measure, the effect of tree species, spout angles and knife heights on cutting force per unit of knife length, and effect of branch diameters on cutting power were evaluated. This experiment results provided the scientific basis for choice of main design parameters of disc branch chipper with short knives.更多还原
