(f) Effects of the invention Since the invention is constructed as described above, it has the following effects.

First, a plurality of auxiliary pulling devices are provided at the front of the pulling device, which has tines projecting in the traveling direction and rotates, and a plurality of auxiliary pulling devices are provided on the front part of the pulling device, which has tines projecting in the traveling direction and rotates.
Since the auxiliary lifting device is arranged to be shifted back and forth, it is possible to prevent culm breakage and ear straining caused by raising grain culms that have fallen down in the left and right directions at once. can be brought about in an orderly and orderly manner.

Second, the main lifting devices 5, 5, the auxiliary lifting device 4, and the auxiliary lifting device 3 are provided, and the drive parts at the upper ends of these lifting devices are located at approximately the same position in side view, and each inclination angle is Although the pulling device is different from A>B>C, the position of the upper end is the same, so the direction in which the lodging grain culm is finally raised is at the same position, so the auxiliary pulling device has a gentle inclination angle C. 3 also has an auxiliary lifting device 4 with an intermediate inclination angle B.
Since both the main lifting device 5 and the main lifting device 5, which have a steep inclination angle A, have the same final lifting direction, there is no gap in the lifting direction even if the angle of inclination is different, and the grain culm moves all at once at the time of handover. This can eliminate the problem of doing so.

In conventional combine harvesters equipped with an auxiliary lifting device in which the main lifting device 5 and the auxiliary lifting devices 3 and 4 are arranged in parallel, the grain culm that has been pulled at a steep slope by the auxiliary lifting device is , a situation occurred in which the machine fell down all at once towards the next main lifting device, which made the handover not smooth and caused a straining situation.In the present invention, this problem has been resolved. This was something that could be resolved.

Thirdly, even when raising a grain culm that has fallen in a complicated manner, it is not necessary to raise it all at once at a steep angle, but in stages, first at a gentle angle, then at a slightly steeper angle, and finally at a steeper angle. Because it is gradually raised, there is no need to pull out the grain culm, tear it into strips, or strain the grain tip.

Fourthly, the lifting start end of the auxiliary pulling device 3 with a gentle angle is placed at the frontmost end, making the length of the lifting device longer. The required horsepower for hoisting is small, and since the main hoisting device 5 is at a steep angle, the required horsepower for hoisting is large, but since the auxiliary hoisting device 3 and the auxiliary hoisting device 4 have already been hoisted to a certain extent, the load is reduced. has become smaller, and the load among the three parties has been balanced.
