Description

The present invention relates to a combine technique including a handling cylinder, a dust-feed port processing cylinder, and a swing sorting device that are pivoted in the front-rear direction of the machine body.
More specifically, the present invention relates to an oscillating dust feeding / conveying apparatus that conveys an object to be processed which has been processed and leaked by a dust feeding port processing cylinder and oscillates and conveys it to the front side of a sorting unit.

Conventionally, in order to improve the threshing performance and sorting performance, the rear side surface of the casing of the handling cylinder that horizontally supports and pivots the rotating shaft in the longitudinal direction of the machine body, and the dust feed port that is horizontally mounted and supported in parallel with the handling cylinder. The front side of the casing of the processing cylinder is communicated with the dust feeding port, and the part of the branches attached to the branch that has not been completely processed (threshing) with the handling cylinder is treated with the dust feeding port. Swing and sorting device that transports the soot and fine swarf that have fallen down through the processing net that forms the lower part of the casing of the processing cylinder by means of a dust transfer conveyor provided below the processing port. A technique for improving the recovery rate of soot by re-introducing it to the front side (starting side of rocking sorting) is known (Patent Document 1, Patent Document 2).
