【発明の属する技術分野】
本発明は扱室内で脱穀処理された穀物をこの下方の揺動選別盤で選別処理するようにしたコンバインの脱穀装置に関する。
【０００２】
【発明が解決しようとする課題】
従来の揺動選別盤にあっては、フィードパンは１枚板に形成され、この後端にチャフシーブが連設される構造となっている。しかし乍らこのような構造の場合、選別巾も狭く、藁屑など塵も塊り状となって分散し難く、特に５条刈り以上など大容量化すればする程この傾向が顕著となって選別精度を低下させるという問題があった。
【０００３】
【課題を解決するための手段】
したがって本発明は、機体の前後方向に軸架する扱胴（６）を内設させる扱室（２２）と、前記扱室（２２）下方に張架させるクリンプ網（２４）と、前記クリンプ網（２４）下方に前端を臨ませて前後方向に揺動自在に支持する揺動選別盤（２５）とを備えたコンバインの脱穀装置において、前記クリンプ網（２４）の下方で揺動選別盤（２５）前部に上下２段に配設した前後フィードパン（２６，２７）と、後フィードパン（２７）後端に連設するチャフシーブ（２９）と、チャフシーブ（２９）下方に配設するグレンシーブ（３０）とを、揺動選別盤（２５）に備えると共に、前フィードパン（２６）の後端に篩い線（２８）を配設すると共に、前フィードパン（２６）の下面側の案内により篩い線（２８）に選別風を送給するプレファン（３１）を設け、また後フィードパン（２７）後端に連設するチャフシーブ（２９）下方とグレンシーブ（３０）下方に選別風を送給する送風装置（３２）をプレファン（３１）後方に設けたもので、２つのフィードパンにより、選別面積を有効に拡大させることができると共に、篩い線による篩い作用で分散する穀物や塵にプレファンからの選別風を良好に作用させて選別性能を向上させるものである。

The feed tines (64a), (72a), (66a), (73a), (68a), and (74a) of the combined conveying tines have the same feed direction, and are raised input pipes (75) that are erected on the cutting frame (12) The lifting input shaft (76) is connected to each transport body (60) via the lateral driving shaft (78) of the lateral driving case (77) at the upper end of the raising case (60) and the branch shaft (80) of the branch case (79). 72) (73) (74) input shafts (81) (82) (83) are interlockingly connected.
[0014]
The branch cases (79) are respectively provided on the upper rear side of the pulling case (60) to drive the pulling tine (59) of the case (60). The upper end of the case (60) is connected, and an output shaft (85) is provided at the lower end of the case (60) to drive the tine chain (84) of the tine (59). (80) is connected to the lateral drive shaft (78) via a pair of bevel gears (86), and the lower end is connected to the output shaft (85) via a pair of bevel gears (87). 60) and the driving tine (59) is driven.
[0015]
The tip transport bodies (72), (73), and (74) are connected to and supported by the lower ends of the second and third branch cases (79) from the left side and the second from the right side, and these transport bodies (72) ( 73) (74) input shafts (81), (82), (83) are linked to each output shaft (85) via a universal joint (88), and each tip conveying tine (72a) (73a) (74a) Each of these is driven.
[0016]
Thus, in the plan view, the tip carrier bodies (72), (73), and (74) are arranged at the opposing positions of the upper carrier bodies (64), (66), and (68), and the respective tines (64a) that are in the mutually opposed relationship. (72a) · (66a) (73a) · (68a) (74a) by making the feeding direction the same direction, the pulling action force to the rear of the cereal hook that has been raised and hooked on the case (60) is large At the same time, the tip transporting tines (72a), (73a) and (74a) transport the position slightly below the neck of the cereal to reduce degranulation, and also cause each tip transporting near the lower position of the drive case (77). The bodies (72), (73), and (74) are arranged so that the pulling action force of the cereals hooked on the drive case (77) is increased, and the upper and lower parts transport bodies (63) to (68) Smooth transport of cereals without catching in the Y-shaped transport path (89) to be formed It is obtained by configured to enable.

【The invention's effect】
As is apparent from the above embodiments, the present invention includes a handling chamber (22) in which a handling cylinder (6) pivoted in the front-rear direction of the machine body is installed, and a crimp net ( 24) and a threshing device for a combine comprising a crimping screen (25) that supports the front end of the crimping net (24) downward and swings in the front-rear direction. swing sorting plate below (25) before and after the feed pan is disposed in two upper and lower stages on the front (26, 27), and chaff sieve (2 9) for continuously arranged in the rear feed pan (2 7) after the end, chaff sieve (29) and Gurenshibu (30) disposed below, Rutotomoni provided on the swing sorting machine (25), with disposed sieve lines at the rear end (28) of the prefeed pan (26), prior to feed The sieving line (28) is guided by the lower side of the pan (26). Pre fan (31) that teapot send another wind provided, also the rear feed pan (2 7) chaff sieve which continuously provided at the rear end (2 9) downwardly and Gurenshibu (30) blowing that teapot feeding sorting air downwardly device (32) pre-fan (31) which was provided in the rear, more two feed pan (26, 27), it is possible to effectively enlarge the screening area, a sieve effect of sieve lines (28) The sorting performance can be improved by allowing the sorting wind from the pre-fan (31) to act well on the dispersed grains and dust.
