昨日の簸箕は板4枚で構成されているようだったが、これは日本の揺り板と同じ一枚物？ 底面形状も曲面になっている。

图为淘金用木簸箕。
清代严如莘《三省边防备览》卷9《山货》记载南郑(汉中)淘金厂用淘床淘金的情况：用木料做淘床，四周有边，淘床上固定一个圆竹筐，将沙倒入筐内，手把住淘床后面的木架，不住的掀簸，用水频洗沙筐，则沙随水流，而金则从筐底缝透下，沉淀于淘床下，淘床两头镶板，中空三尺多，另安木板一块，上面横刻木槽，筐底透出的砂金顺水沉入槽内，另有木匣一个，空出一面，类似簸宾形状，将槽内金砂扫入木匣，在水中淘洗，得到金屑。上述方法，一直沿袭至今，许多工艺先进的选厂，其中摇床、跳汰、旋流等重选设备，尽管工艺先进，但其原理相通。
中国語で使い方が記述されているのかなあ？部分的に意味が分かる気がするけど・・・
The picture shows the gold with wooden dustpan.
Qing Dynasty the Yan Ruyu "three provinces border prepared browse" Volume 9 "sundries" records Nanzheng (Hanzhong) gold plant scouring bed gold: made of wood scouring bed, surrounded by side, scouring the bed fixed a round bamboo basket, sand down into the basket, scouring the bed behind the wooden handle live, could not lift toss, water frequency of sand washing basket, then sand with water, and gold from the seam through the end of the basket, sediment scouring bed scouring bed two set plate, hollow feet, another safety and a wooden board, above the cross carved wood molding, the the placer revealing the end of the basket downstream sink into the tank, while Mu Xia a, empty out the side, similar to winnow Bin shape, tank Jinsha sweep into the Mu Xia, washing in water to get the gold dust. The above method has been followed so far, many of the processes and state-of-the-art processing plant, including a double, jigging, cyclone and other re-election of equipment, despite the advanced technology, but its the same principle.
