Regarding the combined guide rail mounting structure provided.

[0002]

[Prior Art]

 This type of combine has, for example, a structure in which a laterally-rotating type auxiliary conveying device provided at the end portion of a vertical conveying device has the above-mentioned sandwiching and conveying structure, as disclosed in Japanese Utility Model Application Laid-Open No. 55-145133. Are known.

[0003]

[Problems to be solved by the device]

 The auxiliary transfer device has a transfer function that feeds the stem culm whose posture is changed sideways to the feed chain, but there is a tendency for clogging of the stem culm to occur here, and the guide is relatively frequent. Since there is a need to remove the rails and perform work to clear the jam, some combine harvesters were able to move the guide rails away from the endless rotation band by swinging movement. However, with this means, the bolt must first be removed in order to make a swing movement, and the attachment / detachment operation is troublesome, and since it is connected to the machine body even after the swing movement, there is the inconvenience of being an obstacle to cleaning. There was room for improvement. An object of the present invention is to simplify the attachment / detachment operation of the guide rail in the transport device.

[0004]

[Means for Solving the Problems]

 For this purpose, the present invention provides a combiner described at the beginning, in which a support for supporting a guide rail and a frame member to which an endless rotation belt with a protrusion is fixed are attached to a buckle and a disengagement of the buckle. It is detachably attached via an engagement mechanism consisting of a fitting type engagement part that is inserted and removed in accordance with the operation, and the guide rail is moved toward the endless rotation band by the engagement operation of the buckle. It is connected to the frame member in the pulled state, and the support mechanism is detached from the frame member when the guide rail is disengaged from the endless rotation band by releasing the engagement of the buckle. The feature is that the direction is set.

[0005]

[Action]

 When the buckle is removed, the engaging part also comes off, so you only have to remove the buckle to remove the guide rail.In the removed state, the guide rail is completely separated from the machine side, which hinders cleaning. Never. When the buckle is assembled, the engaging part is also fitted, so that the guide rail can be assembled only by the operation of assembling the buckle. Also, due to the mechanism of the buckle, the buckle part on the moving side moves in the direction of separating from the buckle part on the fixed side during the detaching operation, and the buckle part on the moving side is fixed during the assembling operation. It has the property of moving toward the buckle part on the side. Therefore, the relative separation movement direction of both buckle parts by the buckle removal operation is set to the direction in which the guide rail moves away from the endless rotation band, and the relative approach movement direction of both buckle parts by the buckle assembly operation is set. If it is adjusted so that it approaches the endless rotation band, the removal direction will match the direction of the pressing force of the guide rail during the removal operation, and the removal operation will be easy even if the stems are clogged. At the same time, in the assembling operation, the assembling direction coincides with the direction for assisting the pressing urging force, which is convenient.

[0006]

[Effect of the device]

 Therefore, the guide rail can be separated and attached only by operating the buckle, and the movement component associated with the operation of the buckle can be effectively used for the pressing action of the guide rail, which can contribute to the easy attachment and detachment of the guide rail. As a result, we were able to provide a guide rail mounting structure that makes the guide rail attachment / detachment easy and easy, and has practical advantages that do not interfere with cleaning.
