目前的砂金矿床多采用机械化程度较高的采金船开采。采矿系统的挖掘机械为采金船主体设备,其结构多为链斗式。驱动挖斗链的传动装置称为主驱动(或上滚筒)传动装置。它由多棱平面滚筒主轴、减速机构和驱动电动机等部分组成。采金船的主要生产指标之一为小时挖矿量。它是由挖斗容积及装斗量和挖掘速度(即过斗数)来决定的。在采金船的设计中,主驱
The current placer gold deposits are more mechanized mining gold mining. Mining system of mining machinery for the main gold mining vessel equipment, the structure of mostly bucket-type bucket. The drive that drives the bucket chain is called the main drive (or upper drum) drive. It consists of multi-faceted flat drum spindle, reduction gear and drive motor and other components. Gold mining ship one of the main indicators of production for the amount of mining. It is determined by the bucket volume and the amount of bucket and mining speed (ie over the number of votes) to decide. In the design of gold mining vessels, the main drive
