The speed is set to be about 1/2 of the circumferential speed of the raising tine 12 provided in the apparatus 1. By doing so, the tip tine 62 of the tip transfer mechanism 6 raises the culm and does not disturb the posture of the culm that is caused by the tine 12 of the apparatus 1 and does not disturb the posture of the culm. While a sufficient conveying force can be imparted by the tip tine 62, the head loss of the culm can be minimized.
[0028]
Next, the effect | action by the above structure is demonstrated. The split cutting blade 3 is driven to reciprocate via the lower horizontal shaft 22 by the rotational drive of the rotary drive shaft 30 extending from the engine side, and at the same time, via the lower horizontal shaft 22 and the vertical axis 24 and the clutch mechanism 37. Then, the drive horizontal shaft 20 is rotated, and accordingly, each tine 12 of the grain raising device 1 is turned up and down via the sprocket 14 and each side on the side where the transmission mechanism 8 is provided. In the grain raising device 1, the rotational power of the driving horizontal shaft 20 is caused by the vertical linking shaft 26 and the transmission mechanism 8 to cause each grain raising device 1 to raise the tine 12 and each tip conveying mechanism 6. The tip tine 62 and the tine 12 are driven to rotate in conjunction with each other.
[0029]

The partial transport chain 53 is rotationally driven.
[0030]
And the upper and lower parts of the cereals that are cut by the divided cutting blade 3 while being raised by the raising tine 12 of the raising device 1 are transferred to the conveying chains 41, 42, 43 and the upper conveying mechanism of the lower conveying mechanism 4. By transporting to the threshing part C side with the rotational drive of each of the five transport chains 51, 52, 53, the harvested cereal meal can be reliably transported to the threshing part C side.
[0031]
Moreover, at this time, the tip transport case 61 of the tip transport mechanism 6 causes the tip tine 62 to protrude to the feeding action side of the transport chains 51, 52, 53, and causes the grain to be raised in the apparatus 1. Since it is arranged behind the case 11 in the projection of the front view, the cereals are caught on the tip carrying case 61 and the cereal posture is not disturbed to maintain the good posture. The straw can be smoothly and reliably conveyed to the threshing part C side.
[0032]
In addition, in the above embodiment, although the combine for 6 row cutting was shown, in this invention, it can apply also to other combine.
[0033]
【The invention's effect】
