耐久性が低下する問題があった。In such a raising operation, chains are inherently easily stretched, and in particular, chains which are easily covered with mud or water, such as the raised chains, grow remarkably. With the extension of the raising case and the inclination direction of the raising case, the raising chain is greatly slackened in the rearward direction until the raising lug interferes with the upper end side of the peripheral edge of the idler roller on the lower side of the guide base. When the raising lug enters the upper end side of the peripheral portion, it interferes with the edge of the upper end of the peripheral portion to cause damage or breakage due to wear,
There was a problem that durability was reduced.

としたものである。The present invention employs the following technical means in order to solve the above-mentioned problems. That is, a plurality of raising lugs 39 are provided so as to be able to stand up and down at appropriate intervals between a sprocket 46 fixed to the upper side of the guide base 41 and a floating roller 47 supported at the lower end position of the guide base 41. In the grain stem raising portion formed by winding the raising chain 48 and superposing the guide cover 42 on the front side of the guide base 41, the sprocket 46 on the upper side of the non-working side region of the raising lug 39 of the guide base 41 is provided. The gap between the side portion and the upper end side of the peripheral portion 49 of the lower floating roller 47 is notched and opened, and when the raising lug 39 enters the peripheral portion 49 from the notch portion, the peripheral edge portion 49 and the raising lug are opened. In this configuration, the upper end side of the peripheral edge portion 49 is inclined rearward so as not to interfere with the grain 39.

The raising rug 39 rises when passing through the rug guide portion to perform the raising action of the grain stem, and falls down to the non-operation side except for the rug guide portion. In such a raising operation, chains are inherently easily stretched. Particularly, in a case where the chains are liable to be covered with mud or water, such as the raising chain 48, the growth is remarkable. As shown in FIG. 4, the raising lug 39 has a floating roller 47 on the lower side of the guide base 41.
May be greatly slackened in the rearward direction until it interferes with the upper end 50 of the peripheral edge 49, but this loosening causes the lug 39 to enter the upper end side (tongue 50) of the peripheral edge 49. Even if it interferes, the raising lug 39 does not
Damage or breakage due to abrasion generated by interfering with the edge of the upper end on the upper side is avoided.

できる。The turning is performed together with the operation of the auto-lift mechanism R, and at the same time as the turning is completed, the mowing device 1 is lowered by manual operation of the power steering lever 30 and the next row is aligned. And continue the mowing work. At the time of such a mowing operation, for example, when the soil surface becomes soft and the turning which has been turned by the pivot turning is switched to the spin turning, etc., the turning speed becomes much faster because the turning speed is remarkably increased. 1 needs to be kept low, and when the traveling crawler 5 sinks, the rising stop position U of the reaper 1 needs to be raised. The position is changed and adjusted. At the same time as the change and adjustment, the storage setting position of the transmission stop position P can be automatically stored and set at a position lower by a certain interval before reaching the ascending stop position U. At the time of the work, the set positional relationship between the two is always kept accurately and simply at a fixed interval, and when the mowing device 1 is raised by the automatic lift mechanism R, the transmission of the mowing device 1 and the threshing device 9 is performed. No doubt it is possible to automatically stop.

ることも可能である。Conversely, when the transmission stop position P is changed and adjusted, it is possible to store and set the ascending stop position U at a higher position at a certain interval based on the storage setting of the transmission stop position P.
