Description

【考案の詳細な説明】 本考案は、コンバインなどの集稈装置に関する。[Detailed explanation of the idea] The present invention relates to a culm collecting device such as a combine harvester.

従来この種集稈装置は、コンバインなどの進行方向に対
して直角に排稈を集稈し田圃に放出するため、コンバイ
ンなどが刈る場合作業が非常に困難となる。Conventionally, this type of culm collecting device collects waste culms at right angles to the direction of movement of a combine harvester or the like and releases them into the rice field, which makes the work extremely difficult when the combine harvester or the like cuts the rice.

このため刈り取り中に排稈をコンバインなどの進行方向
に対して斜めに放出落下させるか又は一方によせてしま
うことが必要である。For this reason, during reaping, it is necessary to release and drop the waste culm obliquely to the direction of movement of the combine harvester or the like, or to move it to one side.

従来では集稈装置をコンバインなどの進行方向に対して
斜めに設け、コンバインの後面と集稈軸との間に三角形
の流し板を橋架し集稈、放出するものなどが提案されて
いるが、この三角形の流し板は前方の操縦席からは見え
ないためコンバインが後退などするとき道路や堰に当り
破損することが多く、また運搬に際しても不便である。Conventionally, it has been proposed that the culm collecting device is installed diagonally with respect to the direction of movement of the combine harvester, etc., and a triangular sink plate is used as a bridge between the rear surface of the combine and the culm collecting shaft to collect and release the culm. Since this triangular sink plate cannot be seen from the front driver's seat, it is often damaged by hitting roads or weirs when the combine is backing up, and it is also inconvenient to transport.

業性の向上を計らんとするものである。The present invention was proposed to improve the above-mentioned drawbacks, and utilizes the rotation of the culm shaft constituting the culm member, and uses a metal member that cantileverly supports one end of the culm shaft as the center. The culm collecting shaft is rotated in the horizontal direction, and this rotational force is used to automatically release the waste culm to the side of the combine without using any other driving force, making it possible to rationally prevent the waste culm from entering the uncut area. The aim is to prevent this and improve workability.

またこのナツト８を螺退させることにより両者の当接関
係は断たれ集稈軸４はフリーに回転し集稈部は下方に垂
れ下るようにしてある。The contact relationship between the cam plate 9 and the roller 100 is achieved by tightening the nut 8 against the spindle 6.
Further, by screwing back this nut 8, the abutting relationship between the two is severed, the collecting culm shaft 4 rotates freely, and the collecting culm part hangs downward.

図中１２は固定金具である。１３は上記メタル部材５の

このスプリング１６０弾力調整は上記調整ボルト１４に
螺合した調整ナツト１７により行われるものである。In the figure, 12 is a fixing metal fitting. Reference numeral 13 denotes a spring receiver whose upper end is fixed to the lower half of the metal member 5 and has an elongated front shape. Reference numeral 14 indicates an adjustment bolt inserted through the lower end of the spring receiver 13, and the upper end of the adjustment bolt 14 and the A spring 16 for returning the culm member is elastically installed between the spring support 15 provided on the short side 4b of the culm collecting shaft 4,
The elasticity of the spring 160 is adjusted by an adjustment nut 17 screwed onto the adjustment bolt 14.

１８は上記集稈軸４の短辺４ｂ側端に設けたカム板９の
一側に下端を遊動的に連結した連杆である。Reference numeral 18 is a continuous rod whose lower end is loosely connected to one side of a cam plate 9 provided at the end of the short side 4b of the culm collecting shaft 4.

Ｄは補助集稈軸１９と集稈軸４の片持側から他方に向っ
て順次長尺となした数本の補助集稈部２０によって構成

ンバイン本体Ａに対し上記集稈部材Ｃより上方にとりつ
げられている。D is an auxiliary collecting culm member composed of an auxiliary collecting culm shaft 19 and several auxiliary collecting parts 20 which are sequentially elongated from the cantilevered side of the collecting culm shaft 4 toward the other side, and this is clear from the figure. As such, it is attached to the combine main body A above the culm collecting member C.

そしてこの補助集稈軸１９端に一端を固定したレバー２
１の他端に上記連杆１８の上端が軸支されている。A lever 2 with one end fixed to the end of this auxiliary culm collecting shaft 19
The upper end of the connecting rod 18 is pivotally supported at the other end of the connecting rod 18.

次に作用について説明すると、刈取り脱穀調整された排
稈は搬送体１，２に挾持された状態でコンバイン本体Ａ

稈部材Ｃの集稈部３上に順次落下集積せしめられる。Next, to explain the operation, the harvested and threshed culm is held between the conveyors 1 and 2 and transferred to the combine main body A.
are carried to the rear of the combine harvester main body A, and are sequentially dropped and accumulated on the culm collecting part 3 of the culm collecting member C disposed on the rear side of the combine main body A.

集積排稈の重量が設定重量（スプリングの強さにより決
定）を超えるとその重みによって集稈軸４が回転する。When the weight of the collecting culm exceeds a set weight (determined by the strength of the spring), the collecting culm shaft 4 rotates due to the weight.

集稈軸４は逆への字状であってこれの短辺４ｂが軸支さ
れていることから、その屈折角度に対応した分だげ集稈
軸４の長辺４ａは仮想線で示すように大きくコンバイン
本体の側方に回動する。Since the collecting culm shaft 4 has an inverted character shape and its short side 4b is pivoted, the long side 4a of the collecting culm shaft 4 corresponds to the bending angle as shown by the imaginary line. It rotates significantly to the side of the combine main body.

と同時に短辺４ｂ端に設けであるカム板９も回転し、こ
れのカム而が定位置に設定されたローラー１０に作用し
て集稈軸４は支軸６を中心として水平方向に回転する。At the same time, the cam plate 9 provided at the end of the short side 4b also rotates, and this cam acts on the roller 10 set in a fixed position, so that the culm collecting shaft 4 rotates in the horizontal direction about the support shaft 6. .

従って集稈軸４は上記逆への字状となした作用とカム板
の作用の併合により迅速にそして大きく回動され集稈を
コンバイン本体の進行方向に対して片寄りに放出するこ
とができる。Therefore, the collecting culm shaft 4 is quickly and largely rotated by the combination of the above-mentioned reverse-shaped action and the action of the cam plate, and the collecting culm can be released to one side with respect to the direction of movement of the combine main body. .

る。In addition, the rotation of the cam plate 90 pushes up the connecting rod 18, and the lever 21, which has one end fixed to the auxiliary culm collecting shaft 19 by the connecting rod 18, rotates upward, and the auxiliary culm collecting shaft 19
In Fig. 2, the auxiliary culm collection part 20, which has been rotated clockwise and is in a substantially hanging state, is shown by a virtual line (it is assumed to be in a horizontal state, and the culm that is continuously fed by the conveyor is not started). The guide pipe is passed to the collecting culm, and finally the discharge culm is temporarily received.

集積排稈の放出が終るとスプリング１６の作用で全ての
機構は上記と逆に作動し集稈部材Ｃが旧状に復すると同
時に補助集稈部材りも旧状に復し、仮受げした排稈を集
稈部材Ｃ上に移行させ、上述の作用を操り返し行うもの
である。When the discharge of the accumulated culm is finished, all the mechanisms operate in the opposite manner to the above due to the action of the spring 16, and at the same time the collecting culm member C returns to its old state, the auxiliary culm member also returns to its old state, and is temporarily supported. The culm is moved onto the culm collection member C, and the above-mentioned action is repeated.

プリングを集稈軸とコンバイン本体との間に弾設するこ
とができないので、スプリング１６は図のように弾設し
たもので、これは本考案独特のものである。Also, since the collecting shaft 4 rotates counterclockwise, the spring 1
6 is extended so that the reaction force increases, and since the metal member 5 and the collector shaft 4 rotate horizontally, it is not possible to elastically install a spring between the collector shaft and the combine main body as in the past. Since this is not possible, the spring 16 is elastically installed as shown in the figure, which is unique to this invention.

第４図は集稈軸４を直杆とした実施例を示しており、こ

を逆への字状に屈折したことによる回動作用がなくなる
だけである。Fig. 4 shows an embodiment in which the collecting culm shaft 4 is a straight rod, and the effect in this case is almost the same as that of the above-mentioned embodiment, but the action is due to the collecting culm shaft being bent in the opposite shape. It simply eliminates the need for rotation.

ことがなく作業性の向上が計りうるなと実用上の効果は
きわめて大きい。As described above, according to the present invention, the collector shaft is cantilever-supported with respect to the combine main body, and the rotating action of the collector shaft by the collector shaft is utilized to connect the cam provided on the shaft support side of the collector shaft to the combine harvester. By the action of the roller provided on the main body, the culm collecting member can be rotated and rotated to the side to release the collected culm. Therefore, the culm is not released to the uncut area and does not interfere with the reaping work. The practical effect is extremely large, as it improves work efficiency.
