A plurality of dust feeding valves 37 for adjusting the moving speed (residence time) of the threshing in the handling chamber 19 moved toward the front is provided. A dust feed valve 37 is pivotally attached to the lower surface side of the handling chamber upper surface cover 36 above the handling cylinder 21. By adjusting the angle of the dust feed valve 37, the moving speed (residence time) of threshing in the handling chamber 19 can be adjusted according to the variety and properties of the harvested cereal. On the other hand, the grain sorting mechanism 10 disposed below the threshing device 9 is configured by a rocking sorter 22 for specific gravity sorting having a grain pan, a chaff sheave, a grain sheave, and a stroller.

A plurality of dust delivery valves 37 are arranged on the inner surface side of the release side cover 36a so that the amount of dust delivery can be adjusted. That is, the handling chamber upper surface cover 36 is formed in a trapezoidal mountain shape when viewed in the axial direction of the handling cylinder 21, and the release side with the trapezoidal diagonal line of the handling chamber upper surface cover 36 (the opening edge 36c of the release side cover 36a) as a boundary. The handling chamber upper surface cover 36 is divided into a cover 36a and a fixed side cover 36b, and the release side cover 36a is pivotally supported on the upper surface of the handling chamber 19 of the threshing device 9 via a cover spindle 35 so as to be opened and closed.

Provided. The feed end side of the cereal conveyor 32 is communicated with the small-capacity grain tank 6a, and the grain of the conveyor mechanism 30 is directly input from the cereal conveyor 32 to the small-capacity grain tank 6a. For example, the large-capacity Glen tank 6 in FIG. 1 is large enough to contain 12 bags of bag, whereas the small-capacity Glen tank 6a is large enough to hold 2 bags of bag. In addition, on the lower side of the grain outlet 222, two sets of front and rear heel receiving rods 224 to which the candy bag 223 is attached and a candy receiving base 225 are arranged at the right end of the traveling machine body 1.

One can be lightweight in the formation. While the release portion structure (release side cover 36a) or the cover support structure of the handling chamber upper surface cover 36 can be manufactured at low cost, the maintenance workability of the handling cylinder 21 and the like can be improved.

図１乃至図６、図９に示す如く、扱胴２１の軸心線方向視で台形山型に、扱室上面カバー３６を形成し、扱室上面カバー３６の台形対角線（解放側カバー３６ａの開口縁３６ｃ）を境にして解放側カバー３６ａと固定側カバー３６ｂとに扱室上面カバー３６を分割し、脱穀装置９の扱室１９上面にカバー支軸３５を介して解放側カバー３６ａを開閉可能に軸支したものであるから、解放側カバー３６ａの開閉によって、扱室１９の上面の約３分の２を解放でき、扱胴２１のメンテナンス作業に必要な大きさの空間を容易に確保できる。扱室上面カバー３６全体を解放させる従来構造に比べ、扱室上面カバー３６を部分的に解放させることによって、扱室上面カバー３６の解放部構造（解放側カバー３６ａ）をコンパクトかつ軽量に形成できる。扱室上面カバー３６の解放部構造（解放側カバー３６ａ）又はカバー支持構造を低コストに製造できるものでありながら、扱胴２１等のメンテナンス作業性を向上できる。 As shown in FIGS. 1 to 6 and 9, a handling chamber upper surface cover 36 is formed in a trapezoidal mountain shape as viewed in the axial direction of the handling cylinder 21, and a trapezoidal diagonal line of the handling chamber upper surface cover 36 (of the release side cover 36a) is formed. The handling chamber upper surface cover 36 is divided into a release side cover 36a and a fixed side cover 36b with the opening edge 36c) as a boundary, and the release side cover 36a is opened and closed on the upper surface of the handling chamber 19 of the threshing device 9 via the cover support shaft 35. Since it is pivotally supported, about 2/3 of the upper surface of the handling chamber 19 can be released by opening and closing the release side cover 36a, and a space of a size necessary for maintenance work of the handling cylinder 21 can be easily secured. it can. Compared to the conventional structure in which the entire chamber upper cover 36 is released, by partially releasing the chamber upper cover 36, the release portion structure (release side cover 36a) of the chamber upper cover 36 can be made compact and lightweight. . While the release portion structure (release side cover 36a) or the cover support structure of the handling chamber upper surface cover 36 can be manufactured at low cost, the maintenance workability of the handling cylinder 21 and the like can be improved.
