The object of the present invention is to provide a kind of sheller unit; Can carry out the suitable automatic shutter of dust discharge control volume through small-scale operating mechanism; And, avoid the bad generation of action of this operating mechanism easily, and can promptly carry out upkeep operation easily.
To achieve these goals, the present invention relates to a kind of sheller unit, have: discharge the straw conveyer, transport threshing discharge straw with transporting guide rod to the clamping of body rear from process chamber by annular swivel-chain; The dust discharge control volume opens and closes the wind-force dust discharge path of the dust that ejecting outside body by sorting wind evaluates oneself selects portion, it is characterized in that,
Leaning on the threshing feeding chain side; Be provided with mechanical interlinked mechanism, this machinery interlinked mechanism with above-mentioned transport guide rod switch needed displacement to changing to transmit to the switching attitude of above-mentioned dust discharge control volume with the displacement of the clamping direction at interval of above-mentioned annular swivel-chain.
According to this feature structure, if the handled thing amount of sorting portion is many, then the dust discharge control volume by handover operation automatically for opening attitude, if the handled thing amount of sorting portion is few, then dust discharge control volume quilt automatically handover operation for closing attitude.
Because disposing mechanical interlinked mechanism and link to threshing feeding chain side, so can be from transporting guide rod extends a part from the mechanical interlinked mechanism of ground configuration to threshing feeding chain side with the dust discharge control volume from transporting guide rod.Thus; Need not the band fan dust discharge path that crosscut is positioned at the below of transporting guide rod; Can be employed in the formation that the top in this band fan dust discharge path is walked around; For mechanical interlinked mechanism as the operating mechanism of opening and closing operations dust discharge control volume, by the dust of band fan dust discharge path discharge seldom attached on the mechanical interlinked mechanism.
For example; Mechanical interlinked mechanism be configured in the feeding chain side have an opposite side of side; The grain that is configured on the horizontal side that is positioned at sheller unit of machinery interlinked mechanism stores vessel side, when carrying out for the safeguarding of this machinery interlinked mechanism, must get into grain and store between container and the sheller unit and carry out operation; The operation attitude is not good, and the possibility that can not guarantee working space is fully arranged.If guarantee broad working space, then need make grain store the container swing and switch to the measure of opening attitude etc., the also pretty troublesome possibility of preparation work before the upkeep operation is arranged.
