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) The present 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

触しているため摩耗が早いし、受網と適正な隙間
を保持していないと損傷粒や扱残しの発生につな
がる。(Problem to be solved by the invention) If the handling teeth arranged on the outer periphery of the spiral are fixed as in the former case, the peripheral speed of the tooth tips is high and they are constantly in contact with the grains, resulting in rapid wear and damage to the receiving net. If proper clearance is not maintained, damaged grains and unhandled grains may occur.
又、米国特許第4313449号明細書のものはピン
がL型となつていて、先端に穀稈がひつかかり易

ものである。(Means for solving the problem) Therefore, the technical problem of this project is to obtain a threshing machine that does not obstruct the flow of grain culms in a full-feed type axial flow combine and has handling teeth that can cope with wear. The technical means of the present invention to solve this technical problem is to insert the tightening bolt of the handle tooth mounting bracket into the elongated hole for adjusting the handle tooth protrusion of the bracket so that it can be attached to the spiraler. It is composed of
(実施例)
先ず第2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.
作物は掻込リール1で掻き込まれて刈刃2で刈

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

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.

て選別盤9上に還元されるようになつている。 The leakage materials including grains that have fallen from the sorting board are subjected to a sorting wind by a blower fan 12 like a winnowing machine, and the grains fall into the first gutter 13 and the second grains fall into the second gutter 14.
The grains that have fallen into the first gutter 13 are carried to the paddy tank by a grain frying conveyor 15, and the second grains are returned to the sorting board 9 through a thrower tube 16.

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 one in which handling teeth are provided on the peripheral edge of the spiral is a fixed type.
すなわち、第3〜5図において7aはスパイラ
ーで扱歯20はθ角をもつて取付ブラケツト21
に固定され、締付ボルト22をもつてスパイラー
7aに取付けられている。 That is, in FIGS. 3 to 5, 7a is a spiral, and the handling teeth 20 are attached to the mounting bracket 21 at an angle of θ.
and is attached to the spiral 7a with a tightening bolt 22.
従来のスパイラー外周に配設した扱歯では脱穀
処理を促進することになるが、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、
この扱歯は受網と適正な隙間を確保していないと
損傷粒や扱残しの発生につながる。 Conventional handling teeth placed around the outer periphery of the spiral facilitate the threshing process, but the tooth tip has a high circumferential speed and is in constant contact with the grain, so it wears out quickly.
If this handling tooth does not secure an appropriate gap with the receiving net, it will lead to damaged grains and unhandled grains.

1は上方に移動することができるものである。 Therefore, as shown in Fig. 5, an elongated hole 27 is provided in the mounting bracket 21 of the handling tooth 20g, and using this elongated hole 27, the tightening bolt 2 can be adjusted vertically to freely adjust the handling tooth 20g.
2 to the spiral 7a, and when the handling teeth wear out, the tightening bolt 22 can be loosened and the mounting bracket 21 can be slid upward so that the tip of the handling teeth 20g protrudes from the outer periphery of the spiral 7a. The attached bolt 22 is attached to the mounting bracket 21
Slide it into the long hole groove 27 of the mounting bracket 2.
1 is one that can move upwards.

与えない。(Effect of the invention) When the tips of the handling teeth provided on the outer periphery of the spiral of the present invention wear out, the tightening bolt of the handling tooth mounting bracket is loosened, and the handling teeth are protruded toward the outer circumference of the spiral using the elongated hole of the bracket. This feature not only extends the life of the handling teeth, but also allows you to select the appropriate gap between the net and the net depending on the crop as it is vertically adjustable, reducing wasted horsepower consumption and preventing damage. There is. Moreover, in the full-feed type axial flow combine, the handling teeth are straight and follow the spiral, so they do not impede the flow of grain culms and do not affect threshing efficiency.
