装载机在局贮木场作业的临界产量研究

A STUDY ON CRITICAL OUTPUT OF LOADERS AT TIMBER YARD

本文仅就云南省卫国林业局(以下简称卫国局)贮木场实现机械化的适宜产量进行分析和探讨。一、人力作业的盈亏平衡产量卫国局贮场木沿楞深方向有17度坡,设计任务量为7万m^3,库存系数在0.17左右。1—7月为到材季节;全年调拨。生产工艺是:汽车原木到材-初选-归楞-装汽车。除归楞采用“特定坡度”外,包括上楞作业均为人力作业。劳动组织:检尺1人,生产组织1人,卸、选、归、装8人,共10人。

With comparing balance output for profits and losses between hand labour and a loader at the Timber Yard of Weiguo Forestry Bureau, Yunnan Province, their mathematical models for maximum annual output were established, and sloved by a computer. Finally, with comparing production cost between hand lahour and the loader, the critical output completed by the loader is 26610m^3, safe operation rate 95.9％. Meanwhile, the critical output for various amount of loaders is also defined.
