作为重要的可再生能源,枝桠类林业废弃物的高效直燃发电是简便可行的生物质资源再利用方式,然而,目前尚未有适合林区工作的移动式枝桠切碎机。针对这一问题,论文提出了一种适用于林间枝桠实地切削的新型移动式枝桠切碎机。进行了切碎机的整体结构设计,基于TRIZ理论进行了自抬式抓送料装置的创新设计,进行了“渐开线”螺旋式刀辊机构设计,并对平衡臂连杆等关键部件进行了有限元分析。在此基础上,制作样机并进行了性能测试。新型枝桠切碎机外形尺寸1.5×1.2×1.0 m3,重量仅350 kg,处理能力2.7m3/h,适合南方山区就地处理枝桠,可节省运输费用。
As an important renewable energy source, high-efficiency direct-fired power generation of branches and shrubs is a simple and viable way to recycle biomass resources. However, no mobile shredder is suitable for forestry work. In response to this problem, the paper presents a new type of mobile shredder suitable for field cutting of shrubs in the forest. The whole structure design of the shredder was carried out. Based on the theory of TRIZ, the innovative design of the self-lifting catching and feeding device was carried out. The design of “involute ” screwdriver roll was carried out and the key components Finite element analysis was done. On this basis, the prototype was made and the performance test was carried out. The new branch shredder shredder dimensions 1.5 × 1.2 × 1.0 m3, weighs only 350 kg, processing capacity of 2.7m3 / h, suitable for the southern mountainous areas to deal with branches, can save transportation costs.
