所に配設した脱穀装置に関する。[Detailed description of the invention] The present invention houses handling cylinders in which the handling teeth are arranged side by side on the outer periphery with intervals in the direction of the rotational axis, and receiving teeth are arranged in parallel in the direction of the rotational axis of the handling cylinders. A handling room is provided with concave lines arranged in parallel below the handling barrel, and a grain receiving inlet opening at the front of the handling room and a discharge outlet opening at the back of the handling room are installed in all parts of the handling room. Alternatively, a threshing device is provided such that most of the part thereof is relatively offset in the direction of the rotational axis of the handling drum, and a plate-shaped guide device for pressing and guiding the material to be handled toward the discharge port is disposed above the handling drum. Regarding equipment.

穀粒離脱作用及びコンケーブを通した穀粒漏下作
用を含む脱穀性能の向上を図るようにしたもので
あるが、次に述べる不都合があつた。 The above-mentioned threshing device allows the material to be handled to pass through the handling section between the handling drum and the concave two or more times while swirling and flowing around the outer circumference of the handling drum,
Although this was designed to improve threshing performance, including grain release action and grain leakage action through the concave, it had the following disadvantages.
すなわち、扱胴の回転軸心方向に隣接する扱歯
と受歯との扱胴回転軸心方向に沿う間隔を小さく

発生量が多くなることは否めないものであり、そ
の結果、多量のワラ屑のために選別効率が低下し
たり、あるいは、穀粒の品質低下を生じる不都合
が生じるものとなり、改善の余地があつた。 In other words, it is known that the smaller the interval between the handling teeth and receiving teeth that are adjacent to each other in the direction of the rotational axis of the handling drum, the less unhandled grain can be left. The distance between the receiving teeth and the receiving teeth is kept small over the entire range in the direction of the rotational axis of the handling barrel, but although this is suitable for reducing unhandled waste, it also reduces the amount of straw waste generated and damaged grain. It is undeniable that the amount of grain generated increases, and as a result, a large amount of straw waste causes problems such as a decrease in sorting efficiency or a decrease in grain quality, so there is room for improvement. It was hot.
本考案は、穀稈に付着の穀粒は脱穀処理の初期
において大部分が離脱される点に着目し、そのこ
とを有効利用した簡単な改造によつて、扱残し発
生量を抑制する利点を活しながらも、ワラ屑発生
量、及び、損傷穀量発生量を抑制する点にある。 This invention focuses on the fact that most of the grains attached to the grain culm are detached in the early stages of the threshing process, and by making effective use of this fact, a simple modification can reduce the amount of unhandled grains. The aim is to suppress the amount of straw waste and the amount of damaged grain that is generated while keeping the grain alive.
本考案による脱穀装置の特徴構成は、前記扱胴
の回転軸心方向に隣接する前記扱歯と前記受歯の
扱胴回転軸心方向に沿う間隔を、前記受入口に対
応する部分の間隔の方が前記排出口に対応する部
分の間隔よりも小になるようにした点にある。 A characteristic configuration of the threshing device according to the present invention is such that the interval between the handling teeth and the receiving teeth adjacent to each other in the direction of the rotational axis of the handling cylinder is equal to the interval of the portion corresponding to the receiving opening. The difference is that the distance between the two portions is smaller than the distance between the portions corresponding to the discharge ports.
次に、本案特徴構成による作用効果を述べる。 Next, the effects of the feature configuration of the present invention will be described.
すなわち、扱室に供給された直後の穀稈を脱穀

回転軸心方向に沿う間隔を大きくして、その部分
において、穀稈を含む扱対象処理物を不必要に遅
滞させることなく迅速に排出口側へ移動させるよ
うにしてある。 That is, the distance between the handling teeth and the receiving teeth in the portion corresponding to the grain culm receiving inlet where the grain culm immediately after being supplied to the handling chamber is threshed is reduced along the rotational axis direction of the handling barrel. While sufficiently increasing the threshing performance for grain culms immediately after being supplied to the handling chamber, the gap between the handling teeth and receiving teeth in the portion corresponding to the discharge port along the axis of rotation of the handling barrel is increased. In that part, the processed material including grain culms is quickly moved to the discharge port side without unnecessary delay.
従つて、穀稈受入口に対応する部分の扱歯と受

を得るに至つた。 Therefore, most of the grains attached to the grain culm are reliably removed by the handling teeth and receiving teeth of the part corresponding to the grain culm reception opening, and the handling teeth of the part corresponding to the discharge opening Although re-threshing is performed using teeth and receiving teeth to prevent unhandled grain, in that part,
By quickly moving the processed material to the discharge port, the amount of straw waste and damaged grains generated is reduced. A threshing device with great practical advantages has been obtained, which can reduce the amount of generated grains and the amount of damaged grains generated, improve sorting efficiency, and improve grain quality.
