【考案の詳細な説明】
本考案は、扱胴回転軸芯とほぼ平行な軸芯周り
で回転自在で、扱胴との協働により穀稈を切断す
る回転刃を設けた脱穀機に関する。[Detailed Description of the Invention] The present invention relates to a threshing machine that is rotatable around an axis substantially parallel to the rotation axis of the handling barrel and is equipped with a rotary blade that cuts grain culms in cooperation with the handling barrel.
従来、上記脱穀機を構成するに、第６図に示す
ように、回転刃１１を、扱胴２との協働による穀
稈切断部分のみを扱室３内に位置させる状態で配
設していたのであるが、穀稈切断系路１３のスペ
ースが限られているために、穀稈の処理量が増大
すると、穀稈が回転刃１１と扱胴２との間に詰り
易い問題があつた。 Conventionally, in constructing the above-mentioned threshing machine, as shown in FIG. 6, the rotary blade 11 is arranged in such a manner that only the part that cuts the grain culm in cooperation with the handling cylinder 2 is located in the handling chamber 3. However, since the space in the grain culm cutting system 13 is limited, when the amount of grain culm processed increases, there is a problem in that the grain culm easily gets stuck between the rotary blade 11 and the handling barrel 2. .
本考案は、上述従来の実情に鑑みて、回転刃の
配置に対する簡単な改良により、処理穀稈量の増
大による穀稈の回転刃と扱胴との間への詰りを極
力防止し、脱穀処理能力を向上する点にある。 In view of the above-mentioned conventional situation, the present invention makes a simple improvement to the arrangement of the rotary blade to prevent the grain culm from clogging between the rotary blade and the handling barrel due to an increase in the amount of grain culm to be processed, and to process the threshing process. The point is to improve one's abilities.
本考案の特徴構成は、冒記脱穀機において、前
記回転刃の全体を扱室内に配置してあるととも
に、前記回転刃と前記扱胴壁との間に前記回転刃
の外周に沿う迂回経路を形成してある事にある。 The characteristic configuration of the present invention is that, in the above-mentioned threshing machine, the entire rotary blade is disposed within the handling chamber, and a detour path along the outer periphery of the rotary blade is provided between the rotary blade and the handling barrel wall. It lies in the fact that it has been formed.
つまり、処理穀稈量が増大した場合には、回転
刃の全体を扱室内に配置したことにより形成され

を一層確実に防止し、脱穀処理能力を大巾に向上
し得るに至り、しかも、回転刃の配置を変更する
だけの極めて簡単な改良であるから、製作面及び
経済面においても有利にし得るに至つた。 In other words, when the amount of grain culm to be processed increases, part of the grain culm is detoured to the detour path between the handling chamber wall and the rotary blade, which is formed by placing the entire rotary blade inside the handling chamber. As a result, it is possible to reduce the amount of grain culm flowing into the cutting processing path between the rotary blade and the handling barrel, and to suppress an increase in the cutting processing load. It has become possible to more reliably prevent clogging of the grain culm between the grain barrel and greatly improve the threshing processing capacity, and since it is an extremely simple improvement that only requires changing the arrangement of the rotary blades, it is easy to manufacture. This has led to advantages in terms of both economic and economical aspects.

てある。 As shown in Figures 1 to 3, a handling room is equipped with a handling cylinder 2 that performs a rotary threshing operation on the grain culms that are pinched and conveyed rearward by a feed chain 1 extending back and forth on one side of the machine. 3, and a processing chamber 5 in which a processing cylinder 4 for re-threshing the second grain to be described later is installed in parallel in the lateral direction of the machine, and a crimp extending from the handling chamber 3 and processing chamber 5 below them. A sorting section 7 is provided below the handling chamber 3 and the processing chamber 5, which performs wind sorting and specific gravity sorting on the threshed material that is supplied falling through the net 6 to separate it into first grain, second grain, and straw waste. Furthermore, a conveying device 8 for carrying out the first material, a blower conveying device 9 for returning and supplying the second material to the processing chamber 5, a dust exhaust fan 10 for discharging straw waste outside the machine, etc. are provided. It is configured as an automatic threshing machine.

る。 To explain in more detail the threshing processing structure in the handling chamber 3, a rotating straw cutting blade 11 is driven and rotated in the same direction as the handling cylinder 2 around an axis P2 that is substantially parallel to the rotation axis P1 of the handling cylinder 2. In a state where the outer circumferential locus of rotation and the outer circumferential rotation locus of the handling teeth 2a of the handling barrel 2 overlap when viewed in the longitudinal direction of the machine, a plurality of sheets are printed at an appropriate pitch in the longitudinal direction of the machine in the upper part of the handling chamber 3 near the processing chamber 5. The straw waste from the threshed material that is installed in parallel and transferred in the direction of rotation of the handling cylinder 2 as the handling cylinder 2 rotates is shredded and handled by the cooperation of the rotating straw cutting blade 11 and the handling cylinder 2. The structure is configured to facilitate the transfer of the threshing material within the chamber 3 and improve the threshing processing performance, and when viewed in the longitudinal direction of the machine, each rotating straw cutting blade 11 is entirely disposed within the handling chamber 3, and the rotating straw A processed material detour path 12 along the circumferential direction of the rotating straw cutting blade 11 is formed between the cutting blade 11 and the wall of the handling chamber 3, and when the throughput of threshed material increases, part of the processed material is A portion of the material is detoured to the detour line 12 by the rotating action of the rotating straw cutting blade 11, thereby reducing the amount of processed materials to the shredding processing line 13 side between the rotating straw cutting blade 11 and the handling cylinder 2. By reducing the straw waste shredding load, clogging of the material to be processed in the shredding processing line 13 is prevented, the threshing process is made smooth, and the processing capacity is improved.

い。 Incidentally, in forming the detour system 12, as shown in FIGS. 4 and 5, the processing material transferred in the rotational direction of the handling cylinder 2 as the handling cylinder 2 rotates is cut by a rotating straw. Before reaching the blade 11 portion, a partition member 14 having an inverted triangular cross-sectional shape when viewed in the front and rear direction is used to separate and guide the part leading to the detour system 12 side and the part leading to the shredding process path 13 side. The rotating shaft 15 of the rotary straw cutting blade 11 is located in the inner space, and the lower tip thereof is located in the middle of the width of the material transfer path by the rotational action of the handling cylinder 2. In addition to further ensuring the guide of the processed material to the detour system path 12 side, a slit 14a for passing the blade body 11 is formed only in the passage portion of each rotating straw cutting blade 11, and the upper part is covered with a lid member 14b. By locating the rotating shaft 15 of the rotary straw cutting blade 11 in the space inside the partition member 14, straw waste may also be prevented from being wrapped around the rotating shaft 15.

できるようにしても良い。 Furthermore, the tip of the partition member 14 is configured so that its position can be changed freely within the width range of the transfer line for the processed material due to the rotation of the handling cylinder 2, so that the tip of the partition member 14 can be freely changed in position within the width range of the transfer line for the processed material due to the rotation of the handling cylinder 2. The guide amount ratio of the processed material may be changed as appropriate.
