本案は脱穀機とくに全量供給型軸流コンバイン
の脱穀機における扱歯に関するものである。[Detailed description of the invention] (Field of industrial application) This invention relates to a handling tooth in a threshing machine, particularly a threshing machine for a full-feed type axial flow combine harvester.
（従来の技術）
従来の全量供給型軸流コンバインではスクリユ
ー式扱胴で脱穀している。(Prior art) In conventional full-feed type axial flow combine harvesters, grain is threshed using a screw-type handling drum.
そして脱穀処理を促進する目的で扱胴のスパイ
ラー外周に扱歯が固設されている。 In order to facilitate the threshing process, handling teeth are fixed to the outer periphery of the spiral of the handling barrel.
又、扱胴のスパイラーにＬ型ピンを設け、その
Ｌ型ピンを回動させてピン先端のスパイラーに対
する平面視角度を調節自在としたものは、米口特
許第4313449号明細書に記載されている。 Furthermore, a device in which an L-shaped pin is provided on the spiral of the handling barrel and the L-shaped pin is rotated to freely adjust the angle of the tip of the pin in plan view with respect to the spiral is described in Yoneguchi Patent No. 4313449. There is.
（考案が解決しようとする課題）
以上の如くスパイラー外周に配設した扱歯が固
定であると、そのスパイラー周縁に対する傾斜角
が小さい場合処理が向上するが消費馬力が大とな
る。(Problems to be Solved by the Invention) As described above, if the handling teeth disposed on the outer periphery of the spiral are fixed, if the angle of inclination to the periphery of the spiral is small, the processing will be improved, but the horsepower consumption will be large.
逆に傾斜角が大きい場合消費馬力は小となるが
扱残しやササリ粒が増す。 On the other hand, if the angle of inclination is large, the horsepower consumption will be small, but the amount of unhandled grains and grains will increase.
又、歯先周速が高い上に穀粒と絶えず接触して
いるため摩耗が早いし、受網と適正な〓間を保持
していないと損傷粒や扱残しの発生につながる。 In addition, the peripheral speed of the tooth tip is high and it is constantly in contact with the grain, so it wears quickly, and if the proper distance between the tooth tip and the receiving net is not maintained, damaged grains and unhandled grains may occur.
更に、米国特許第4313449号明細書のものはピ

ある。(Means for solving the problem) Therefore, the technical problem of the present invention is to obtain a threshing machine with handling teeth that can cope with the difficulty of threshing without interfering with the flow of grain culms in a full-feed type axial flow combine harvester. The technical means of the present invention to solve this technical problem is that when providing the handling teeth on the outer periphery of the spiral of the screw type handling cylinder, the handling teeth that protrude in the radial direction from the outer periphery of the spiral are connected to the feeding surface of the spiral. The inclination angle with respect to the outer peripheral edge of the spiral in the direction viewed toward the feeding surface of the spiral can be freely adjusted.
（実施例）
先ず第４図をもとにして従来の全量供給型軸流
コンバインから説明する。(Example) First, a conventional full-feed type axial flow combine harvester will be explained based on FIG. 4.
作物は掻込リール１で掻き込まれて刈刃２で刈

フイーダーハウス４のチエーンコンベア５で扱室
６に運ばれ、スクリユー式扱胴７すなわち、スパ
イラー付扱胴で脱穀される。 The crops are raked in by the raking reel 1 and cut by the cutting blade 2, and the cut crops are conveyed from the raking auger 3 to the handling room 6 by the chain conveyor 5 of the feeder house 4, and then transferred to the screw type handling cylinder 7, i.e. The grain is threshed using a handling barrel with a spiral.
脱穀されたものは受網８から揺動選別盤９上に
落下し、送風フアン１０と揺動選別盤９により選
別される。 The threshed grains fall from the receiving net 8 onto the oscillating sorting board 9 and are sorted by the blower fan 10 and the oscillating sorting board 9.
この選別過程で穀類と細かい藁屑は揺動選別盤
から下方に漏下し、長藁のみ排塵口１１方向に運
ばれる。 During this sorting process, grains and fine straw waste leak downward from the oscillating sorter, and only long straw is carried toward the dust outlet 11.

以上のような全量供給型軸流コンバインにおい
てスパイラーの周縁に扱歯を設けた従来のものは
固定式である。 In the above-mentioned full-feed type axial flow combine, the conventional type in which handling teeth are provided on the periphery of the spiral is a fixed type.
すなわち、第５〜７図において７ａはスパイラ
ーで扱歯２０はθ角をもつて取付板２１に固定さ
れ、ボルトナツト２２をもつてスパイラー７ａに
取付けられている。 That is, in FIGS. 5 to 7, reference numeral 7a denotes a spiral, and the handling teeth 20 are fixed to a mounting plate 21 at an angle of θ, and are attached to the spiral 7a with bolts and nuts 22.
以上の如く固定式であつて傾斜角θが小さいと
処理は良くするが馬力が大となる。 As described above, a fixed type with a small inclination angle θ provides good processing but requires a large amount of horsepower.
逆に傾斜角θが大きいと馬力は少ないが、扱残
しやササリ粒が増すので作物に合せ調節するのが
望ましい。 On the other hand, if the inclination angle θ is large, the horsepower will be low, but the amount of unhandled grains and small grains will increase, so it is desirable to adjust it according to the crop.

Attach c to the circular mounting plate 21, and tighten the bolts and nuts 2.
2 fixes the mounting plate 21, and 23 is a tightening screw consisting of a bolt and nut in the center.

高能率で作業することができる。 In this case, if the angle of inclination is θ 1 < θ 2 < θ 3 , loosen the bolts and nuts, rotate the mounting plate 21, and project the one with a different angle of inclination from the periphery of the spiral 7a. For crops that can be set but have difficulty in shedding, use the tips of the handling teeth 20a with a small inclination angle, such as angle θ, to give sufficient thrashing action and eliminate the loss of unhandled grains, loss of grains, and cutting of branch stalks. can be prevented. On the other hand, for crops that are easily shed, the handling teeth 20c with a large inclination angle, such as the inclination angle θ 3 , are used, so that the work can be performed with high efficiency by reducing the horsepower consumption and not thrashing the grain more than necessary.

が変えられるようになつている。 The ones in Figures 2 and 3 replace the one in Figure 1, and the one in Figure 2 has one handling tooth 20d with inclination angles θ 1 and θ 2 attached to the mounting plate 21, and the mounting plate can be switched up and down. It can be mounted with a bolt/nut 22, and the one shown in Fig. 3 is configured so that a mounting plate 21 with one straight tooth 20e can be rotated around a mounting bolt/nut 24, and the rotated position is The bolt and nut 25 are attached to the mounting plate 21.
The handle teeth 20e can be slid in the slit grooves 26, and the angle of inclination of the handling teeth 20e can be changed by rotating the mounting plate 21.
以上何れにしても本案のものは扱歯の傾斜角が
変えられるようにすることにより作物は適合した
脱粒作用ができるものである。 In any case, in the present invention, by changing the angle of inclination of the handling teeth, the grain can be shed in a suitable manner.

きるという特徴がある。(Effect of the invention) The handling teeth provided on the outer periphery of the spiral of the present invention protrude in the radial direction from the outer periphery of the spiral, and moreover, protrude in a shape parallel to the feeding surface of the spiral, and are The angle of inclination relative to the outer edge of the spiral in the viewing direction is adjustable, so for crops that are difficult to shed, the angle of inclination of the handling teeth can be reduced to provide sufficient thrashing action to prevent unhandled grains, loss of kernels, or cutting of branch stalks. On the other hand, for crops that are easy to hustle, the inclination angle is increased to prevent the grain from being pounded more than necessary, reducing horsepower consumption and enabling highly efficient work.
