TECHNICAL FIELD The present invention relates to a leaf tobacco foreign matter separation work table for separating from a leaf tobacco and a method for separating and collecting leaf tobacco.

  Conventionally, various foreign substances (sand, insects, side buds, weeds, covered vinyl pieces, metals, dust, etc.) that are discharged by picking leaf dry leaves have been considered. In particular, leaf tobacco with a cultivated field in the sand dune region has a remarkable adhesion of sand to dry leaves, and it takes considerable time to separate sand during picking work. In the cultivation field of leaf tobacco in the sand dune area, sprinklers sprinkle water, the rain jumps from the ground surface and adheres to the leaf tobacco leaves, or the sand that soars by the wind attaches to the leaf leaves, and this sand adheres conventionally. Has been a problem.

  However, conventionally, such a method is not used for the separation work of the sand on the picking work table, and the sand adhering to the dry leaves is selected while selecting the quality of the dry leaves on the picking work table. The workers only need to manually perform the separation process one by one, and the sand separation process takes much time and effort.

  On the other hand, the picking work table used for the picking work also serves as a leaf filling work table for filling the harvested leaf tobacco leaves with a hanging tool (see, for example, Patent Document 1). When filling fresh leaves, the rainwater adhering to the fresh leaves is drained from the fresh leaves by means such as blowing (about 30 minutes) before the leaf filling operation.
