Abstract
A harvesting and threshing machine having a crop collecting platform carrying a threshing cylinder extending across its full crop collecting width. Crop threshed by the cylinder passes to a straw conveyor mounted behind the cylinder which collects the threshed crop and conveys it laterally. The straw conveyor may itself effect grain separation or may pass the crop to grain separation apparatus.
Claims9
A crop harvesting and threshing machine including a mobile frame;
- a crop collecting platform attached to the mobile frame;
- lift means to raise and lower at least part of the platform relative to the mobile frame;
- a crop threshing cylinder means rotatably supported on the platform for rotation about its long axis and extending across substantially the full crop collecting width of the platform;
- a concave mounted adjacent to the crop threshing cylinder means and cooperable with said crop threshing cylinder means to thresh crop material received by the crop collecting platform;
- feed means to feed cut crop material to the crop threshing cylinder means;
- a grain separating apparatus including a straw conveyor mounted on the platform and extending across substantially the full crop collecting width of the crop collecting platform, said straw conveyor including flight means for moving straw in a direction parallel to the long axis of the crop threshing cylinder means, and a screen concave member cooperating with the straw conveyor to separate grain from crop material which leaves the crop threshing cylinder means;
- a grain cleaning means mounted on the mobile frame;
- conveyor means for receiving the grain separated by the grain separating apparatus and conveying the grain received to a grain cleaning means;
- conveyor means for receiving straw from the straw conveyor;
- and drive means for driving the crop treating mechanisms of the crop harvesting and threshing machine.
