7c and 7c are fixedly provided, the rear support rod 3c is provided with bosses 37d at both left and right end portions at the rear end portion thereof.
7e is fixedly provided, and after this, a substantially V-shaped receiving rod 37f is protruded rearward and fixedly provided on the boss 37d on the right side of the support rod 37e.

The rear sweeping frame 38 is provided with a front supporting plate 38a at the front end as shown in FIG.
Reference numeral a is a structure fixed to the rear support rod 37e of the front scraping frame 37. The front support plate 38a includes a support frame 38 in the front-rear direction.
b is fixedly provided, and the middle support plate 3 is attached to the support frame 38b.
8c and a horizontal support frame 38d are fixedly provided, and a rear support plate 38e is fixedly provided on the horizontal support frame 38d.

Auxiliary holding device 3 of the middle transport drive device 39
The support plate 33b of No. 3 is the rear support plate 3 of the rear sweeping frame 38.
The drive holding device 39a of the middle conveyance drive device 39 is provided on the receiving rod 37f of the front scraping frame 37 in addition to being mounted on the 8e.
It is mounted on the rear end portion of the vehicle.

As a result, since the upper side surface of the drive holding device 39 can be configured to be smooth, the flow of straw waste or the like becomes good, and the accumulation of straw waste can be prevented. From the right side in the plan view, the scraper 40 for preventing the winding of straw on the star wheel 4a of the scraping device 4 for scraping the second grain of the grain stalk is divided into front and rear scrapers as shown in FIG. It is configured to be attached to the insert frame 37 and the rear scraping frame 38.

The front mounting plate 40a provided on the front side of the scraper 40 is a front receiving plate 41a provided on the front scraping frame 37.
In addition to mounting with a bolt and nut, the rear end of the scraper 40 is mounted with a bolt and nut on a rear receiving plate 41b provided on the rear scraping frame 38. is there.

As a result, it is possible to prevent the straw from being wrapped around the star wheel 4a. In addition, since the rear end of the scraper 40 is located outside the outer circumference of rotation of the star wheel 4a, the detachability can be improved and the grain transfer path can be secured, and when mud, stocks, etc. enter. However, clogging can be prevented.
