取り作業が行われている。In the two-step cutting type having the first cutting blade for grain cutting and the second cutting blade for adjusting the height of the stump, the second cutting blade is integrated with the cutting section. The mowing operation is performed by lowering or raising the second cutting blade at the same time when the mowing portion is lowered to start mowing and when the mowing portion is raised to finish mowing.

If the second cutting blade is cut badly by catching on the blade and the second cutting blade rises together with the mowing part at the end of cutting, the grain culm between the first and second cutting blades should be the first cutting blade only. It leaves it as an uncut culm of a high stump harvested by.

A second cutting blade lifting mechanism is provided, and second cutting blade lifting control means for lifting the second cutting blade with a set time delay from the lifting of the mowing unit is provided. After passing through the first cutting blade, only the stumps that have been mowed to a substantially constant height by the second cutting blade are mowed by the second cutting blade to maintain this mowing performance stably, and at the end of cutting, the first cutting blade is used. It is possible to cut all high stumps after cutting without leaving them as uncut stumps with the second cutting blade, and to make all the stumps in the entire field have a uniform low cutting height.

The cutting blade (21) is subjected to follow-up control as shown in the flowchart of FIG. 9, and the vehicle speed, which is the working speed, is input to the controller (110) through the sensor (106),
When the lowering of the mowing unit (9) is input by the switch (109), the vehicle is traveling due to the relationship between the distance (L) between the first cutting blade (20) and the second cutting blade (21) and the vehicle speed (V). The set time (T) required for the second cutting blade (21) to pass between the first and second cutting blades (20) and (21) is calculated (T = L / V), and the set time (T) has elapsed. After that, the second cutting blade (21) is lowered to the lower limit ground contact position of the sled body (31), and the second cutting blade (21) is driven by the engaging operation of the cutting blade clutch (81). In other words, the second cutting blade (21) does not start descending at the same time when the cutting unit (9) starts to descend at the beginning of cutting, and the second cutting blade (21) does not move to the passing position of the first cutting blade (20). The second cutting blade (21) is lowered after the set time to reach, and the traces of the stumps mowed by the first cutting blade (20) are constantly removed by the second cutting blade (21).
First cutting blade (20)
The second cutting blade (21) prevents the second cutting blade (21) from catching on the second cutting blade (21) when the uncut portion is cut with the second cutting blade (21).

After cutting to the last stump, the second cutting blade (21) is raised to prevent the first cutting blade (20) from remaining as a high stump, and the entire field is kept at a low stump. It is what

The rotation control of the Karaku (95) is performed on the basis of the detection value of the grain culm amount sensor (107), and when the quantity of grain culm put into the threshing unit (4) is larger or smaller than the standard, the Karaku (9)
The speed of 5) is controlled to be increased or decreased to a large or small value to stably maintain the sorting accuracy.

The outside of b) is a rotating body (11
8) is rotatably supported in a tilted posture from front to back and front to back, and the grain input port (8a) of the fried grain barrel (8) is faced to the rotation center of the tank (117) on the upper end side of the tilt, and the lower end of the tilted The tank rotation shaft (119) of the tank is connected to the engine (15) side through the gear transmission mechanism (120), and the tank (117) is connected.
It is configured so that the branch can be separated and removed from the paddy while the paddy is stored in the tank (117) by rotating and rotating the paddy so as to rub the paddy inside each other. Further, in this case, by making both ends of the tank (117) into a conical shape, the interference with the machine is suppressed to a minimum, and further, the grain input port (8a) of the lifted grain angle (8) is rotated by the tank (117). By making it the center, the grain intake formed on the side of the tank (117) can be made into the minimum shape to enable the smooth intake of the paddy into the tank.

するものである。As is apparent from the above embodiments, the present invention is a normal combine harvester in which the second cutting blade (21) for adjusting the height of the stump is provided behind the first cutting blade (20) for grain cutting. A second cutting blade elevating mechanism (36) for independently elevating and lowering the second cutting blade (21) is provided, and the second cutting blade (21) is moved up and down with a set time delay from the elevating of the mowing section (9). Since the second cutting blade lifting control means (110) is provided, the first cutting blade (20) passes through the remaining straw at the beginning of cutting.
Mow only the stumps after they have been mowed to a substantially constant height with the second mowing blade (21) to maintain stable mowing performance, and mow with the first mowing blade (20) at the end of mowing. After cutting all the high stumps without leaving them as uncut stumps with the second cutting blade (21), all the stumps in the entire field can be made to have a uniform low cutting height to improve the post-processability. It has a remarkable effect.
