Embodiment Construction

[0019] figure 1 A threshing device according to the invention is shown. The material, which is advantageously seed straw, is fed into the threshing device through an inlet 1 located on a first gable side of the threshing device. The threshing device comprises an outer space 2 connected to the inlet 1, in which a screw feeder 3 is arranged. Several inclined elongated elements 4 form a conical section between the outer space 2 and the inner space 5 . The threshing device comprises a first rotatable unit 6 which is rotatably arranged around a central axis 6a. The first rotatable unit 6 comprises a shaft 8 connected to the radially outward cylindrical portion 7 by a plurality of first connection elements 9 . The shaft 8 is rotatably mounted in a first bearing 10 on the first end face side of the threshing device and a second bearing 11 on the second end face side of the threshing device. The cylindrical portion 7 is connected to three elongated flails 12 by a plurality of seco...

Abstract

The present invention relates to a threshing device for threshing of a material. The threshing device comprises a threshing part with a first rotatable unit (6) which comprises at least a flail (12) and a concave (15) which surrounds the rotatable unit (6). Preferably, the concave (15) is rotatably arranged in an opposite direction in relation to the first rotatable unit (6). The threshing device comprises a cleaning part with a rotatably mounted sieve (16), which surrounds the concave (15). A fan (28) is arranged to provide an air stream towards the sieve (16) for preventing the cleaned parts of the threshed material to pass through the sieve (16). The air stream is also arranged to transport out the cleaned parts which are collected in a space (18) between the sieve (16) and the concave (15).

Description

technical field [0001] The present invention relates to a threshing device for threshing materials, wherein the threshing device comprises: a first rotatable unit comprising at least a flail; a concave plate rotatably arranged on the threshing In the device and at least partially surrounding the rotatable unit; rotatably mounted screen, the screen surrounds the concave plate; and a first conveying device arranged in the space between the first rotatable unit and the concave plate The material is fed and conveyed in a substantially axial direction so that the material undergoes threshing in a threshing gap formed between the flail of the first rotatable unit and the inner surface of the concave plate. Background technique [0002] Conventional combine harvesters for straw with seed have a shearing table at the front part, in which the straw of the crop is cut off and the straw of the crop is then fed into a subsequent threshing device. The threshing apparatus consists of a t...
