A rear transmission shaft 20d is provided at a rear portion of the front sprocket 20b that is pivotally supported by the front sprocket 20b of the transmission shaft 22b, and the rear sprocket 20e is pivotally supported by the rear transmission shaft 20d. The front / rear sprockets 20b and 20e and the upper and lower sprockets 35b have a configuration in which a tip transfer chain 20h equipped with a tip lug 20f is spanned at predetermined intervals.

With the transmission shaft 22b of the transmission case 22 as a rotation center, the transfer start end side of the tip transfer chain 20a can be rotated up and down.
The upward movement control of the transfer start end of the tip transfer chain 20h of the waste tip transfer device 20 is controlled by the feed chain 5a and the holding rod 5b depending on the transfer amount of the cereals that are pinched and transferred. It is the structure which carries out rotation movement control of the transfer start end side of 20h. The lower limit position on the lower side of the transfer start end portion of the tip transfer chain 20h is configured to be positioned above the feed chain 5a.

  Further, in the above configuration, the inclination angle on the transfer start end side of the tip transfer chain 20h of the waste tip transfer device 20 is changed and controlled in conjunction with the traveling vehicle speed of the travel device 8 as shown in FIG. . In this configuration, the inclination angle is largely controlled by the high traveling vehicle speed.

  As a result, the transfer start end portion of the tip transfer chain 20h of the waste tip transfer device 20 is set to the up-and-down rotation movement method, and the up-and-down rotation movement is controlled in conjunction with the traveling vehicle speed. Can be prevented. Good evacuation treatment is possible.

  The inclination angle (θ1) of attachment of the spiral plate 23c mounted on the dust removal cylinder 23a of the waste treatment chamber 25 and the inclination angle (θ2) of attachment of the resistance plate 19a of the resistance element 19 for sludge grains are shown in FIG. As shown in the figure, the structure is provided with substantially the same inclination angle.

Thereby, the taking over of the dust removal processed material to the dust removal treatment chamber 25 becomes good.
The height (H) in the vertical direction of the resistance plate 18b of the threshing room resistor 18 in the front threshing chamber 6 is set to be higher than the height (H) in the vertical direction of the resistance plate 19a of the small grain resistor 19. It is the structure which provided and increased resistance.

Thereby, in the said small grain dropping chamber 7, a grain is rarely extracted, For this reason, a big resistance can be applied and a small grain can be taken reliably.
The resistance plate 18b of the threshing room resistor 18 provided on the inner side surface of the handling cylinder cover 17 of the front machine threshing room 6, the one side part of the threshing machine 3, the upper side surface of the traveling chassis 2, or the 4 parts of the reaping machine. As shown in FIG. 9, the handling chamber motor 18d provided at any one of the locations is connected by a wire 19e, a resistance plate 18b of the threshing chamber resistor 18, and a resistance plate 19a of the bristle grain resistor 19. Both of them are configured such that the resistance can be individually changed and controlled by the individual motors 18d and 19b.

  As a result, when the second reduction amount increases, the amount of dust is increased, so that it is transferred to the rear part, and the resistance is increased in the crushing particle dropping chamber 7 and communicated with the dust processing chamber 23 to be discharged. Can be supplied.

The resistance plate 19a of the resistance element 19 for the coarse grain provided in the casual grain dropping chamber 7 has a configuration in which resistance is always added as shown in FIG.
Thereby, in the said small grain dropping chamber 7, resistance can always be added by not having to transfer the waste material of a threshing processed material back.

  As shown in FIGS. 15 and 16, the threshing machine 3 is configured to have a threshing chamber 6 and a small grain dropping chamber 7, and the feed chain 5a is divided into two parts. Is a configuration in which an inner feed chain 5c and an outer feed chain 5d are provided outside the inner feed chain 5c on the left outer side of the threshing chamber 6. The transfer end portion of the outer feed chain 5d and the transfer start end portion of the inner feed chain 5c are polymerized by a predetermined dimension (L3), and the inner feed chain 5c has a predetermined dimension (L4) toward the threshing chamber 6 side. It is the structure provided in the polymerization state.

  The inner feed chain 5c is configured to rotate at a constant rotational speed. In addition, the outer feed chain 5d is configured to be rotationally driven by a transmission (not shown) in conjunction with the traveling vehicle speed.

  Thereby, by making the rotational speeds of the inner feed chain 5c and the waste spike tip / root transfer devices 20 and 21 the same, the succession of the waste is improved. Further, the layer thickness of the waste can be reduced in the small grain dropping chamber 7, and the recovery of the small grains is improved.

  On the rear side of the grain storage tank 3a for discharging the grains stored in the grain storage tank 3a to the outside of the machine, a discharge support cylinder 43 having a vertical transfer spiral 43a as shown in FIG. A discharge auger 44 is provided at the upper end portion of the discharge support cylinder 43 so as to be extendable and extendable at the upper end of the discharge support cylinder 43. The discharge spiral 44a discharges the grain to the outside of the combine 1 in the longitudinal direction.
