A spiral cylinder having a transfer spiral is used for the grain discharge cylinder of the combine harvester. The discharge cylinder at the tip of the spiral cylinder must have a safe structure in which the discharge resistance of the grain is small, and moreover, it is difficult for the fingertip or the like to reach the rotating part of the transfer spiral. If the discharge port at the lower end of the discharge cylinder is deepened or made small, it is safe and grain can be accurately discharged to a long distance, but the grains are likely to be clogged in the discharge cylinder particularly in the upper portion of the spiral shaft.

EFFECTS OF THE INVENTION The grain transferred from the combiner grain tank side to the spiral tube 2 by the rotation of the transfer spiral 1 flows down the discharge tube 5 and is discharged from the lower discharge port 4 to a target extraction position. When the grain transport action from the discharge port 4 is delayed due to an increase in the transport amount in the spiral cylinder 2 or the presence of straw waste in the discharge port 4 of the discharge cylinder 5, the discharge cylinder 5 Will enter the discharge chamber 6 formed widely in the upper part, and will absorb the grains from the discharge port 4 that have been delayed in discharging, and the grains in this discharge chamber 6 will be discharged from the discharge port 4. It is quickly discharged by releasing the discharge resistance.

As described above, even if the discharge port 4 of the discharge cylinder 5 is not widely opened, the grain-absorption capacity of the discharge chamber 6 makes it difficult to give a resistance to the conveyance from the side of the spiral cylinder 2 and is smooth.
Safe graining can be performed. Moreover, since the grains are less compressed in the discharge chamber 6, clogging due to the compaction of the grains does not occur.

A discharge tube 5 provided at the tip of the horizontal spiral tube 2.
Has an inner diameter larger than that of the horizontal spiral cylinder 2 and is provided with a discharge chamber 6 which is largely bulged upward and has a lower end discharge port 4 which is appropriately lengthened downward. The spiral shaft 3 is the spiral cylinder 2
It is rotatably supported by an integral bearing 19 on the outer side of the end wall 18 of the spiral cylinder 2 from the tip of the inside of the discharge cylinder 5. When discharging the harvested grains stored in the Glen tank 10 to the outside of the machine, the vertical spiral cylinder 16 and the horizontal spiral cylinder 2 are transferred by driving the transfer spiral of the bottom gutter 17, and the discharge cylinder 5 is discharged. It is discharged from the discharge port 4. When there are many grains flowing down from the horizontal spiral cylinder 2 to the discharge port 4 of the discharge cylinder 5, the rotation spiral of the transfer spiral 1 causes the grains that are swirled and discharged into the discharge cylinder 5 to follow around the spiral shaft 3. However, when the discharge from the discharge port 4 is carried out quickly and the resistance becomes small, the grains in the discharge chamber 6 also flow down to the discharge port 4 and are discharged. . Moreover, the grain at the discharge port 4 is less likely to be subjected to the grain pressure, and the downward flow is performed quickly.

In FIG. 4, the point different from the above example is that the horizontal spiral tube 2 is constituted by an auger receiver 21 that can switch and support the storage position C lower than the horizontal position and the storage position D lower than the horizontal position. Is. The auger receiver 21 is composed of two upper and lower stages, and is attached to and supported by the upper end of the fried machine 11. The upper receiving seat 22 is formed in a Y shape and supports the lower surface of the horizontal spiral cylinder 2 when the cylinder 20 is shortened and the horizontal spiral cylinder 2 is lowered. At this time, the angle of the horizontal spiral cylinder 2 is inclined so that the discharge port 4 side is positioned higher. Therefore, when the grains are not discharged during the combine operation, even if there are residual grains in the horizontal spiral cylinder 2, they do not flow out to the discharge port 4 side and return to the base side, so that the residual grains do not leak out. .
