Description

  The present invention relates to a combine for harvesting and selecting threshing planted cereal grains in a field.

  The harvesting operation of napped cereals with a combine is performed at the front part of the traveling chassis of this combine, and the cereals are caused by a plurality of pulling devices provided at the front part of the reaper that cuts and transports the cereal. Then, it is harvested while being scavenged by each of the plural scoring devices provided, and the harvested cereal meal is transferred to the rear upper part.

  As shown in Japanese Patent Laid-Open No. 9-168325, the cereals harvested as described above are provided at predetermined intervals to the auxiliary lug conveying chain of the auxiliary lug type tip conveying apparatus provided on the lower right side from each scraping device. It is transported by the take-up transport lug and provided on the left and right sides. It is handed over by the nail part of the drive scraper of the right-hand tip transfer device and the left-hand passive scratch body nail portion, and is taken into the lug transfer chain of the tip transfer device at a predetermined interval. The tip of the cereal is taken over by the take-up transfer lug that is installed and installed, and the stock side of the cereal is taken over by the take-up and transfer chain of the stock take-up and transfer device. And threshing.

As in the present invention, the root side of the harvested cereal of the one side row (right side) is taken over and transferred to the rear upper part by a lower right / upper right root transfer device that is divided into upper and lower parts. On the upper side of these upper right / lower right root transfer devices, the tip side of the harvested cereal rice bran is taken over and transferred to the rear upper part by providing a tip transfer device. Moreover, the transfer to the rear upper part taking over the root side of the harvested cereal rice cake of the other side row (left side) is transferred by the left root transfer device. The tip side of the harvested cereal rice bran is transferred to the rear upper part by providing a supply transfer device. The conventional culm transfer device has a significantly different structure from the culm transfer device as in the present invention.
JP-A-9-168325

  From the auxiliary lug type tip conveying device on the lower right side, the harvested cereal rice bran is driven by the take-up transfer lug of the lag conveying chain of the tip take-up conveying device, from the drive scraper of the right tip taking-up and conveying device and the left side passive bite. The tip side of the grain culm is taken over and transferred to the upper rear part. Also, the stocker side of the cereal grain is taken over by the takeover transport chain of the stock source transfer and transport apparatus, transferred to the upper rear part, and handed over to the threshing machine. Thus, the threshing is carried out while nipping and transferring the inside of the threshing machine. As a result, the structure until the cereal is scraped and cut, the cut cereal is transferred to the rear upper part, and supplied to the threshing machine is complicated. Due to the simple structure and complexity of this, spillage of the cereals due to dripping of the cereals and severance of the cereals may occur, but these problems are to be solved. Is.
