The invention relates to a threshing and separating device in which a rotating threshing drum leaving a narrow gap coaxially within a concave / screen casing unit that surrounds it circumferentially is arranged, wherein the concave screen casing unit is designed with the same cross-section as the drum and at one end with a Material feed opening and at the other end with material discharge devices is equipped for the threshed-out good.

According to the main patent it is provided that the threshing drum and the concave screen casing unit are truncated conical, the passage of the goods in the axial direction takes place, and that the concave sieve shell unit Kornsammei- and conveying devices for collecting and diverting the material passing radially through the concave / screen jacket unit are.

According to the main patent, at the thicker end of the Threshing drum elements in the form of wings attached to the threshing drum shaft, which hold the crop from Throw away the circumference of the drum. Sieves are provided near the wings so that the threshed Well thrown from the wings against the sieves to achieve a final separation before the material is ejected from the device.

This threshing and separating device according to the main patent can be used as an independent unit can also be used in particular as part of a combine harvester.

In order to increase the effectiveness of the end separation, the invention provides that as an outward-facing Elements rods are provided.

If the Gutsaustrageinrichtung has an impeller and sieves surrounding the impeller, see the invention provides that the rod-like members are arranged within the sieves.

In a further expedient embodiment, the rod-like members generate suction Wings attached, which are arranged at the end of the drum.

An exemplary embodiment of the one designed according to the invention Device is shown in the drawing.

The figure shows a sectional view of part of the threshing and cleaning device.

This figure corresponds essentially to FIG. 4 of the main patent.

It shows a conical threshing drum 31.a and a conical concave sieve salt unit 43 c /, the threshing and separating device

surrounds the threshing drum. In the gap between the threshing drum 31a and the concave / screen set unit 43 α , the crop is conveyed in the axial direction, ie from left to right when looking at the figure. The crop is subjected to a threshing and cleaning treatment in which the grain passes through the concave / sieve set unit in a radial direction.

The straw and chaff remain in the gap and emerge from this at the end of the drum. Here straw and chaff are grasped by rod-like members and thrown in the radial direction away from the threshing drum 31 a against a sieve 52 a. The rod-like members 75 extend essentially radially outward. They are attached to wings 76 which are arranged at the end of the threshing drum 31 α. The straw and chaff are then diverted from the combine harvester or the device through a pipeline (not shown) or a conveyor funnel. The wings 76 generate an air flow which supports the movement of the straw and the chaff directed against the sieve 52 a

and effects a post-cleaning before the discharge takes place.

Claims (3)
