Description

  The present invention relates to a rocking sorter applied to a combine.

  A threshing device that performs threshing processing on the cereals conveyed by the cereal conveying device, and along the width direction of the machine so that the first and second items of the threshing threshed by the threshing device are aggregated, respectively. Conventionally, it has been known to apply a swing sorting apparatus having a feed pan and a chaff sheave mechanism that swings integrally in the longitudinal direction of the machine body to a combine having the first and second baskets arranged in parallel. (For example, see Patent Document 1 below).

  In such a combine, when a large amount of threshing containing a relatively large amount of spiked material falls from the threshing device to the rocking sorting device, the sorting function of the rocking sorting device is impaired. Specifically, for example, in the feed pan, the flow of the whole threshing is deteriorated by the fallen spikes, and the action of the feed pan is that the threshing is transported backward while being dispersed in the body width direction. Damaged. And, in the chaff sheave mechanism adjacent to the rear side of the feed pan, the cut piece sent from the feed pan to the front end portion close to the feed pan and the fall piece dropped directly from the threshing device As a result, the sorting performance of the chaff sheave mechanism at the front end is impaired. This problem becomes significant especially when the threshing apparatus is not equipped with a receiving net.
