【考案の詳細な説明】 (イ) 産業上の利用分野 本考案は穀稈を脱穀処理する脱穀機における排
塵移送装置に関する。[Detailed description of the invention] (a) Industrial application field The present invention relates to a dust transfer device in a threshing machine for threshing grain culms.

(ロ) 従来技術 従来、扱室の側部に移送室と処理室とからなる
処理部を設けた脱穀機は実公昭57−35232号公報
等により既に知られている。(b) Prior Art Conventionally, a threshing machine having a processing section including a transfer chamber and a processing chamber on the side of a processing chamber is already known from Japanese Utility Model Publication No. 35232/1983.

(ハ) 考案が解決しようとする問題点 前記既知の脱穀機は処理性能を良くするため処
理胴及びそれを内装する処理室を大径にし、移送
室およびそれに内装した移送螺旋は被処理物を移
送するだけで良いので小径にしていたが、処理室
が扱室の真横になるので機幅が大になると共に処
理物が揺動選別体の中間部に落入するので選別性
能が低下した。(c) Problems to be solved by the invention In order to improve processing performance, the known threshing machine has a large diameter processing cylinder and a processing chamber in which it is installed, and a transfer chamber and a transfer spiral installed in it have a large diameter to improve processing performance. The diameter was small because it only needed to be transferred, but since the processing chamber was located right next to the handling chamber, the width of the machine became large and the material to be processed fell into the middle of the oscillating sorting body, resulting in a decrease in sorting performance.

(ニ) 問題点を解決するための手段 本考案は前述の問題点を扱室の側部に移送室を
設け、その後部に大径の処理室を設けることによ
り解消した。(d) Means for solving the problems The present invention solves the above-mentioned problems by providing a transfer chamber on the side of the processing chamber and a large-diameter processing chamber at the rear thereof.

そして、被処理物を小径の移送室から大径の処
理室に移行させるべく、それらの間を円錐状に形
成すると共に螺旋を有する円錐胴を介装したとこ
ろ狭い移送経路が折曲するため移送抵抗が大にな
つて高能率脱穀を行なつたり、漏れた殻稈を脱穀
したりして処理物量が多くなると詰りを生ずると
いう新たな問題点が発生した。 In order to transfer the material to be processed from the small-diameter transfer chamber to the large-diameter processing chamber, a conical barrel with a spiral shape and a spiral shape was inserted between the two, but the narrow transfer path was bent. A new problem has arisen in that when the resistance becomes large and the amount of material to be processed increases due to high efficiency threshing or threshing of leaking culms, clogging occurs.

このような問題点を処理胴と前記移送螺旋を螺
旋付き円錐胴で連結し、前記移送螺旋とその外側
板との間隙より円錐胴とその外側板との間隙を大
きくすると共に円錐胴と対向する外側板にリード
角を有するガイド板を取付けて移送経路幅を広く
すると共にガイド板により被処理物の移行を助長
することにより解決した。 To solve this problem, the processing cylinder and the transfer spiral are connected by a conical cylinder with a spiral, and the gap between the conical cylinder and its outer plate is made larger than the gap between the transfer spiral and its outer plate, and it is opposed to the conical cylinder. The problem was solved by attaching a guide plate with a lead angle to the outer plate to widen the width of the transfer path, and by using the guide plate to facilitate the transfer of the material to be processed.

(ホ) 作用 扱室内で発生した脱穀物のうち穀粒や小さな藁
屑は通常の脱穀機と同様受網から揺動選別体上に
落入して選別され、比較的大きな藁屑や穂切れ等
の排塵物は移送室に送込まれ、それを移送螺旋が
後方の処理室へ移送する。(E) Function Grain and small straw waste generated in the threshing room are sorted by falling from the receiving net onto the oscillating sorter like in a normal threshing machine, and comparatively large straw waste and ear pieces are sorted out. etc. are sent into the transfer chamber, and the transfer spiral transfers them to the processing chamber at the rear.

そして、被処理物が移送室から処理室へ移行す
る時、円錐胴と対向する部位で移送通路が折曲す

れるので、詰りを生ずることなく処理胴の外周へ
スムーズに移行する。 When the object to be processed is transferred from the transfer chamber to the processing chamber, the transfer path bends at the part facing the conical barrel, but since the transfer path becomes wider, the transfer resistance does not increase and the transfer path bulges out. Since the object to be processed is received by the guide plate having a lead angle and guided rearward, it smoothly moves to the outer periphery of the processing cylinder without causing any clogging.

がない。 Relatively short pieces of straw, ears, etc. enter between the pitches of the spiral blades of the transfer spiral 22 and are transferred, and long straw approaches or separates from the outer periphery of the transfer spiral 22 on the dust sending port 25 side, or is repelled. In other parts, it is transferred while being pressed against the outer plate 31,
If a large amount of waste is generated in the handling room 2 by harvesting, transporting, and threshing a large amount of grain culms with a multi-row harvesting combine, or by supplying wet grain culms for threshing processing, the The part facing the rear wall 32 of the handling chamber 2 on the side of the dust port 25 is rapidly constricted, so it tends to stagnate and become clogged, and on the outside, it becomes compressed and tends to become clogged, but the notch in the rear wall 32 section 33 and transfer spiral 22
Since the gap with the outer periphery of the straw is widened, the straw can be transferred smoothly to the processing chamber 17, and the long straw compressed on the side of the outer plate 31 is transferred to the processing chamber 2 as the transfer spiral 22 rotates.
When it moves to the side, it moves to the processing chamber 17 through the wide gap H, and no clogging occurs.

生するのを防止することができる。(g) Effect of the invention As mentioned above, this invention has a transfer chamber 1 on the side of the handling chamber 2.
A processing chamber 17 having a larger diameter than the transfer chamber 16 is connected to the rear of the transfer chamber 16, and a transfer spiral 2 is provided in the transfer chamber 16.
2, and a processing cylinder 23 having a larger diameter than the transfer spiral 22 is mounted in the processing chamber 17, and the processing cylinder 23 and the transfer spiral 22 are connected by a conical cylinder 34 with a spiral 34a. Since the gap between the conical barrel 34 and its outer plate 35 is made larger than the gap with the outer plate 31, and a guide plate 36 having a lead angle is attached to the outer plate 35 facing the conical barrel 34,
When the material to be processed that has entered the transfer chamber 16 from the treatment chamber 2 is transferred to the processing chamber 17 by the transfer spiral 22, even if the amount is large, there is a large space corresponding to the conical cylinder 34 between the transfer spiral 22 and the processing cylinder 23. Processing cylinder 2 via the transfer passage
3 smoothly transitions to the outer periphery of the conical body 34.
Although the transport route of the corresponding parts has become wider,
The guide plate 36 provided on the inner peripheral surface of the outer plate 35 works together with the transfer action of the spiral 34a of the conical barrel 34 to move the objects to be sorted without stagnation, and as a result, the width of the machine can be made narrower. However, clogging between the transfer chamber 16 and the processing chamber 17 can be prevented.
