During the harvesting of the culm by the combine, the dividers 19a, 19b, and 19c sown the two-rowed planting culm, and the raising devices 20a and 20b raise the culm for each line, and the cutting blade device 21 The culm caused by the reaping is cut off, and the culled culm obtained in this way is raked by a belt 27a,
27b is raked to the center of the cutting width, and the left and right star wheels 28a, 28b operate to rake the raked grain culm bitten by the concave and convex teeth and send it to the transfer start end of the backward transfer device 29. At this time, the guide rod 90
a, 90b, 91a, 91b, 92a, 92b guide the cut culm in a specific direction. During this operation, the amount of grain culm per hour (cutted grain culm amount) that is cut by the cutting blade device 21 frequently changes due to the density of the planted grain culm, the slowing of the machine body traveling speed, and the like.

When the amount of the cut culm becomes excessive or the posture of the cut culm deteriorates, the star wheel 28a,
Accurate scraping by 28b is disturbed, and Star Wheel 2
In some cases, clogging of the harvested culm occurs between 8a and 28b. In such a case, the following measures are taken.

After the operator stops the operation of the combine,
By turning the knob bolt 86 by hand, the screw portion is removed from the female screw portion 85 of the additional piece 83, and further removed from the through hole of the support piece 86 to release the connected state of the knob bolt connecting means 82, and then hold the cover member 80a. Then, as shown by the imaginary line k in FIG. 8, this is swung outward around the drive shaft case 24a to move the one star wheel 28a away from the other star wheel 28b.

Accordingly, the left and right star wheels 28
As shown in FIG. 8, a wide open state is established between the a and 28b. Under this state, a hand is inserted between the left and right star wheels 28a and 28b to remove the cut grain culm jammed here. I do.

When the removal operation is completed, the cover member 80a is swung inward to return to the original position, and the screw portion of the knob bolt 86 is inserted through the through hole of the support piece 86 to make the additional piece 8
3 and screwed into the female screw portion 85 of the
2 is returned to the coupled state. Thereafter, the combine is brought into the operating state again, and the harvesting operation is continued.

Next, a modification of the above embodiment will be described. The knob bolt connecting means 82 is omitted, and instead one star wheel 28a is connected to the other star wheel 28a.
Therefore, a tension spring is stretched between, for example, the support arm member 77 and the reaping portion frame (the support frame member 23a) so that the star wheel 28a is in the free state. The concavo-convex teeth of the star wheel 28a and the other star wheel 28b mesh with each other and are pressed by the elastic force of the tension spring. At this time, the elasticity of the tension spring can be released by a simple operation, so that, for example, the hooked portion of the tension spring can be easily removed.

According to this, when the amount of harvested grain culm becomes excessive, one of the star wheels 28a is pressed against the elasticity of the tension spring in accordance with the amount of the other.
8b, and the separating operation prevents clogging of the harvested culm between the left and right star wheels 28a, 28b.

If the cut culm is clogged between the star wheels 28a and 28b in spite of such a separating operation, the elasticity of the stalk is removed by removing the hooked portion of the tension spring and the like. In the same manner as in the case of the example, the star wheel 28a is raised to the left to swing outward around the transmission shaft case 24a to remove the clogged grain culm. Thereafter, the star wheel 28a is returned to the normal position, And restoring the elasticity of the star wheel 28a.

Conversely, when the amount of culled grain is too small during the cutting operation, the left and right star wheels 28a, 28a, 28b are used in the state of use of the star wheels 28a, 28b as in the previous embodiment.
When the relative arrangement of the 28b is fixed, the stable scraping by the star wheels 28a and 28b tends to be impaired, but in the case of this modification, even when there is no amount of harvested grain culm, one of the two Since the star wheel 28a is pressed against the other star wheel 28b, even if the harvested culm is small, it can be bitten by an appropriate resilient pressure, and can be accurately sent to the transport start end of the backward transport device 29. It will be.
