Design And Research Of Movable Twig Chipping Device

Nowadays the abandoned twig material production in biomass granule fuels, biomass, biomass fuel, made all raw twig material to the problem of economic transportation in forest area. Therefore, whether research and develop a will on the forest twigs of mechanical equipment on-site smashing processing, then reuse of complementary monitoring. Through the mobile molding machinery processing into pellet fuel for later transport, power generation and making oil further processing technologies and equipment using provide support, has the important practical significance and important economic significance. This paper aim at the requirement current forest region of the actual need research:attempts to make a worker family already available forest and wheeled tractor traction twig material conveniently on twigs of the portable type smashing processing machinery equipment, with its crushed for energy-oriented use twiges of forest region, providing a practical convenient mechanical equipment.Traditional hammer-shape pulverizer with high energy consumption, not suitable for direct be used for of woodiness material smashing processing short coming. This thesis research in total in biomass "chopped than shatter province of work" by academic views biomass power plant cutting and hammer of crushing the design thought, join together with research design a diagonal cutting twigs set "with hammer of break woodiness slice" in one of the tractor traction mobile crushing machine twigs. Based on the analysis of the diagonal cutting mechanism twigs established bevel, cutting model, and analyzes the advantage and disadvantage; This paper explains in detail the structure design of mobile twig crusher schemes and characteristics and the selection of parameters calculation; Application of 3D-modeling software Pro/e to its various parts, complete the machine assembly drawings, and for the motion simulation institution conducted interference. Finally using ANSYS Workbench 12.0 for the carrying larger key parts the statics of finite element analysis, and the main shaft system modal analysis, and verifies the feasibility and rationality of design.The research results can be in forest areas in 10～100mm diameter level of 5mm twig material crushing processed into the woodiness grain under twigs, to adapt to the transportation, forest creatures pellet formation fuel processing production, biomass and bio-fuels production application, also can provide help for production of forest fungus.
