Combined harvesting this invention refers to a combined reaper (10) comprising a cross -cutting unit of threshing (26) which is prepared to receive and thresh a harvest chain. Separation apparatus (32, 36) are located downstream and behind the threshing unit and are willing to receive the threaded harvest current and carry in a backward direction.The threshing unit and the separation apparatus,Have their grids (34, 42) to allow grain and straw into pieces to fall under the action of gravity on an underlying thresher tray (28) and separator tray (44),Respectively. The thresher tray is operated in an oscillating way to carry a primary stream of grain / straw in pieces back,To a rear border (49) from which the primary stream of grains / straw into pieces falls under the action of gravity in a cleaning unit (48). The separator tray is also operated in an oscillating way to carry a secondary grain / straw current in piecesTo a front edge from where the secondary stream of grains / straw into pieces falls under the action of gravity to combine with the primary grain / straw current into pieces. The cleaning unit comprising a fan (52) to generate a clean air current (xY,Which is directed through the stream of grain / straw into pieces falling. The front edge of the thresher tray is arranged forward to the rear edge of the thresher tray by an overlay distance so that the fragmented grain / straw secondary current falls into the thresher and stratified tray before falling from its rear edge.ceifeira combinada a presente invenção refere-se a uma ceifeira combinada (10) que compreende uma unidade transversal de debulha (26) disposta para receber e debulhar uma corrente de colheita. aparelhos de separação (32, 36) estão localizados a jusante e para trás da unidade de debulha e dispostos para receber a corrente de colheita debulhada e transportar em uma direção para trás. ambos, a unidade de debulha e o aparelho de separação, compreendem respectivas grelhas (34, 42) para permiti
