The reaching means 41 is slackened, and the left and right arms 36 of the drive link member 37 rotate around the attachment shaft 38, whereby the tips of the front and rear arms 35 of the drive link member 37 reciprocate in the left and right direction. The sliding contact member 31 is reciprocated by reciprocating the 34 in the left and right direction.

  The operating mechanism of the scraper 30 is configured to reciprocate the pair of drive transmission means 40 and 41 attached to the drive link member 37 in the left and right direction using the drive source of the supply transport chain 13B. There is no need to provide a source, and costs can be reduced.

  Since the scraper 30 causes the scraper 30 to reciprocate in the left-right direction by operating the drive link member 37 by the drive gear 42 which is a drive source of the supply transport chain 13B, the working mechanism of the scraper 30 can be simply configured.

  The one-side drive transmission means 40 and the other-side drive transmission means 41 are arranged point-symmetrically with respect to the axis of the output shaft 44 of the drive gear 42 (follower gear 43). It can be converted to reciprocating motion well.

The drive transmission means 40 and the other side drive transmission means 41 can be arranged.

  The drive gear 42 of the supply and transfer chain 13B and the output shaft 44 of the supply and transfer chain 13B are configured to be freely releasable (removable) by so-called coupling connection, and the one side drive transmission means 40 and the other side drive transmission means 41 Since the drive gear 42 is configured to be able to be engaged with the drive gear 42 separated from the shaft 44, when the drive gear 42 is separated from the output shaft 44 of the supply transport chain 13B, the drive transmission unit 40 makes the drive gear 42 free rotation. The sheave 23 and the drive link member 37 can be manually adjusted to an arbitrary position at the time of connection of 41, facilitating the assembling operation and reducing the number of assembling steps and preventing the adjustment error.

  That is, the base of the rotating body 48 which rotates integrally with the driving gear 42 is attached to the driving gear 42, the mounting pin 49 is provided at the tip of the rotating body 48, and the one side drive transmitting means 40 is locked from the front side of the mounting pin 49 The other drive transmission means 41 is engaged from the rear side of the mounting pin 49, and the first drive transmission means 40 engaged with the mounting pin 49 from the front side is wired forward as it is and the chain rail 45 is rotated. The one-side drive transmission means 40 which detours the movement shaft 46 and is locked from the rear side of the mounting pin 49 once arranges the wiring toward the rear, converts the arrangement direction to the front, and rotates the chain rail 45 Because the first drive transmission means 40 and the second drive transmission means 41 are locked to the drive link member 37, the rotating body 48 is integrally rotated by rotation of the drive gear 42 at the time of reap threshing operation. Then of the rotating body 48 The position of the mounting pin 49 at the end changes back and forth with respect to the axis of the drive gear 42, thereby converting the rotational motion of the drive gear 42 to the mounting pin 49 of the rotating body 48 into a reciprocating motion. The one side drive transmission means 40 and the other side drive transmission means 41 transmit to the drive link member 37 to reciprocate the scraper 30.
