けてある脱穀装置に関する。[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a top plate of a handling room accommodating a handling barrel, and a threshing side plate that can be swung open / close around an axis provided on one side of the top plate. The present invention relates to a threshing device which is attached to a top plate and which is provided with a lock mechanism for fixing the closed state of the top plate across the other side of the top plate and the upper part of the threshing side plate.

下揺動すべく軸支して構成されている。In this type of threshing device, the lock mechanism has been previously used by the present applicants in connection with FIGS. 7 to 9 of Japanese Utility Model Application No. 63-126482.
There is one proposed in the figure, and this locking mechanism has an engaging pin protruding laterally from the threshing side plate and a rocking member with a groove that engages with this engaging pin vertically swings around the horizontal axis. It is configured to be pivotally supported.

タ付きは好ましいことではなかった。[Problems to be Solved by the Invention] Therefore, although the lock mechanism sufficiently exhibits its function when the top plate is pulled out upward,
There was no function of restricting the horizontal movement of the top plate in the direction of the pivot axis of the lock member. There is also some locking function at the pivot that pivotally supports the top plate on the threshing side plate, but since this is a swinging support point, rattling or the like is inevitable in production, and horizontal movement is also possible at the pivot point of the top plate. We could not expect much regulatory effect. Therefore, coupled with the fact that the top plate, which does not require sufficient strength to support the load, has a thin plate structure, the top plate itself is liable to move due to machine body vibrations, etc. Since it is a large part that covers only the parts, the horizontal movement of the top plate and the rattling phenomenon in response to the vibration of the airframe have spread to other parts and caused those vibrations. Further, as shown in FIG. 1, in the case of an axial-flow type handling drum (9) in which a spiral handling tooth (9a) is wound around a rotary drum, a threshed material is provided along the inner surface of the top plate (12). The dust transfer valve (29) for guiding the threshed material may be provided on the inner surface of the top plate (12) as proposed in Japanese Utility Model Application No. 63-126482. In the case where the plate has a guide function for the threshing processed product, if there is movement or backlash of the top plate as described above, the guiding function of the threshing processed product will be significantly impaired, and in any case, Moving the top plate and rattling was not desirable.
本考案の目的はロック機構とは別に簡単な機構を設ける
ことによって、天板のガタ付き・移動等を抑制して振動
原因を取除くことができるものを提供する点にある。It is an object of the present invention to provide a simple mechanism in addition to the lock mechanism, which can suppress the backlash and movement of the top plate and eliminate the cause of vibration.
本考案による特徴構成は前記天板の他側部と前記脱穀側
板上部とに亘って、前記天板が閉塞状態で水平方向へ移
動するのを規制する係合式規制機構を設けてある点にあ
り、その作用効果は次の通りである。A characteristic configuration according to the present invention is that an engaging-type restricting mechanism for restricting horizontal movement of the top plate in a closed state is provided over the other side of the top plate and the upper part of the threshing side plate. , Its effects are as follows.
例えば、第３図の係合ピン（26A）と係合孔（28a）のよ
うな係合式の規制機構（25）を新たに設けることによっ
て、上下方向へは前記ロック機構（18）によって移動を
規制され、水平方向へは前記係合式規制機構（25）で移
動を規制され、結局、天板（12）は移動・ガタ付きを規
制される。For example, by newly providing an engaging type restricting mechanism (25) such as the engaging pin (26A) and the engaging hole (28a) in FIG. 3, the lock mechanism (18) can be moved vertically. The top plate (12) is regulated and its movement in the horizontal direction is regulated by the engagement type regulation mechanism (25).

係合式規制機構を追加するだけの改造ですみ、製造コス
ト面で有利である。As a result, rattling and movement of the top plate is restricted, which contributes to the reduction of vibration and the like, and when applied to an axial-flow-type handling cylinder, it has the effect of smoothing the flow of the threshing material. In addition, it is only necessary to modify the top plate itself by increasing the strength and weight of the top plate to prevent rattling of the top plate. It is advantageous in terms.
請求項２で記すように、係合式規制機構を係合ピンと係
合孔で形成した場合に、係合孔等の内周縁が係合ピンと

とも何れか一方を取換えできる構造によって、“ダレ”
等による天板のガタ付き等の再発生を食い止めることが
できる。As described in claim 2, when the engagement type regulation mechanism is formed by the engagement pin and the engagement hole, the inner peripheral edge of the engagement hole or the like is "dull" during a long period of time by repeated contact with the engagement pin. May occur. Therefore, a structure that can replace at least one of the engagement pin and the engagement member is used to "drip"
It is possible to prevent the recurrence of backlash of the top plate due to the above.
