2. Description of the Related Art Conventionally, in the raising device for a harvester as described above, one of the first fixing means and the second fixing means is attached to a different diameter hole formed in the raising frame and a decorative cover. A different-diameter engagement tool pivotally supported around the front-rear axis,
A makeup for a pull-up frame is performed by configuring the different-diameter engagement tool inserted in the different-diameter hole from the front portion of the makeup cover so as to raise the engagement posture and the engagement release posture with respect to the frame. By making it easy to attach and remove the cover, and forming a recess where the operation tool is stored in the operation tool attachment site on the makeup cover, it is possible to prevent the operation tool from contacting other objects such as planted culms during traveling. The applicant of the present invention has proposed a device capable of preventing the disadvantage that the different-diameter engagement tool is rotated and accidentally pulled up and the engagement of the different-diameter engagement tool with the frame is released (for example, See Japanese Patent Application No. 6-185603, etc.).

However, it is general that the makeup cover is attached to and detached from the raising frame from the front of the raising device. In the above-mentioned prior art, the work of attaching and detaching the makeup cover to the raising frame is performed. In order to prevent accidental rotation due to contact with other objects, the operating tool that is formed in a shape that is easy to grasp from the front of the pulling device is housed in the recess formed in the cosmetic cover. Since it is difficult to grab from the front of the raising device, it is necessary to take an improvement measure to make it easier to attach and detach the decorative cover to and from the raising frame.

According to the present invention, in the engaging posture of the different-diameter engagement tool with respect to the pull-up frame, the different-diameter engagement tool is brought into a state of being raised and abutted against the frame by the biasing of the spring. The rotation suppressing force of the different-diameter engagement tool in the fitted posture is increased. In other words, when the different-diameter engagement tool is rotationally operated by the operation tool coming into contact with another object such as a planted grain culm, it unexpectedly raises and the engagement of the different-diameter engagement tool with the frame is released. It becomes possible to more strongly prevent such inconveniences. On the other hand, in the disengagement posture of the different-diameter engagement tool with respect to the pull-up frame, the operation tool is projected to the front of the makeup cover by the biasing of the spring, so that the operation tool can be easily moved from the front of the pull-up device. You can grab it.
That is, by grasping the operating tool that is in a protruding state as the disengagement engagement tool is disengaged from the raising frame, the makeup cover can be attached to and detached from the raising frame more easily. In addition, when the makeup cover is attached to or detached from the raising frame, the operation tool is used as a handle for attachment / detachment work. hand,
It is possible to reduce the manufacturing cost and avoid the inconvenience that the planted grain culms are entangled with the protrusions formed during the harvesting work.

Is for urging the different-diameter engagement tool 27 to be brought into contact with the upper plate-shaped body 17 of the frame 10, and in the posture for releasing the engagement with respect to the frame 10, the operating tool 28 causes the concave portion 16a of the makeup cover 16 to move. It is constituted by a spring 29 that urges it to project forward from. The spring 29 is interposed between a concave portion 26b formed in the reinforcing plate 26 of the decorative cover 16 and having a circular shape in a front view, and the operating tool 28. That is, the raising frame 10
The different-diameter engagement tool 27 in the disengaged posture with respect to is pulled up against the bias of the spring 29 and inserted into the different-diameter hole 17b of the frame 10, and after the insertion, the operation tool from the front part of the makeup cover 16 By rotating 28, the different-diameter engagement tool 27 is switched from the disengaged attitude to the engagement attitude with respect to the pull-up frame 10 rotated by 90 degrees.
Can be engaged with the frame 10.

The different-diameter engagement tool 27 includes a pull-up frame 10
When the different-diameter engagement tool 27 is engaged with, a pair of protrusions 27a that engage with the left and right common holes 17c formed in the upper plate 17 are formed. The engagement between the common hole 17c and the protrusion 27a is held by the biasing force of the spring 29. Further, when the pull-up frame 10 is engaged with the different-diameter engagement tool 27, the operation tool 28 is fitted in the recess 16 a of the makeup cover 16. That is, the different-diameter engagement tool 27 is rotationally operated by vibration during traveling or contact with other objects such as the planted culm of the operating tool 28, so that the different-diameter engagement with the different-diameter engagement with the frame 10 is unexpectedly caused. The inconvenience that the engagement of the tool 27 is released can be prevented.

As shown in FIGS. 4 and 7, the operating tool 28
Is the state where the decorative cover 16 is raised and is not attached to the frame 10 (the different-diameter engagement tool 2 with respect to the raised frame 10).
7 is not engaged), the makeup is changed from the state in which the spring 29 urges the concave portion 16a of the makeup cover 16 [states shown in (b) of FIG. 4 and (b) of FIG. 7]. The cover 16 is adapted to switch to a state in which the cover 16 is projected forward (a state shown in (a) of FIG. 4 and a state of (a) of FIG. 7) so that the front of the raising device 6 can be easily grasped by hand. Therefore, when the makeup cover 16 is attached to or detached from the front of the raising device 6, the makeup cover 16 is attached to or detached from the raising frame 10 by gripping the operation tool 28 in the protruding state. Can be done easily. That is, the operation tool 28 is configured to function as a work handle when the work of attaching and detaching the makeup cover 16 to and from the pull-up frame 10 is performed.
