And the ultrasonic sensor S10 is input to the CPU 101, the front cereal culm sensor S1 and the rear cereal culm sensor S2 respectively detect and input the conveyed culm, and the short culm sensor S3 detects the culm length. Although the input is input, the handling depth adjusting device 26 (FIG. 3) uses the CPU 101 to output the detection outputs from the tip sensor S4 and the stock sensor S5.
Is controlled by a manipulation signal output from the CPU 101 based on the control signal, and the handling depth is automatically adjusted via the connecting rod 27 (FIG. 3). In this case, the control device 100
Determines that the position where the tip position of the transported grain stem passes between the tip sensor S4 and the stock sensor S5 is the position of the most suitable handling depth, and adjusts the adjustment position of the handling depth adjustment device 26 to that position. Control.

Next, when the combine 1 reaches the ridge of the field and shifts to the cutting of the headland, the ridge switch S1 is set in order to prevent the tip of the weeding tool 8 from colliding with the ridge rising at the end of the field.
3, while the cutting and lifting cylinder 13a (FIG. 3)
Can be extended to raise the cutting device 6, and when the height (t) reaches a predetermined value, the switch S13 is turned off to stop the raising of the cutting device 6, and the cutting of the culm is started.

That is, in the high cutting work on the bank, when the cutting device 6 is raised by a predetermined amount to start cutting the culm of the headland, the CPU 101 transmits the position information of the cutting device 6 from the cutting position detection sensor S9 to the CPU 101. Then, the detection information that the grain culm from the front grain culm sensor S1 is being fed is input.

Here, the control device 100 includes the short culm sensor S
When the grain culm detection information from the culm 3 is inputted, the grain culm length is determined to be longer than the reference value, and only the handling depth adjusting device 26 is controlled, and the grain culm detection information from the short culm sensor S3 is inputted. When it is not performed (non-detection information), it is determined that the grain stalk length is shorter than the reference value, and the control by both the handling depth adjusting device 26 and the supply / transportation device 30 is performed at the same time. A very short culm can be supplied to the threshing apparatus 15. In this case, the very short culm is the feed chain 14
Therefore, all the culms are transported by the auxiliary feed chain 17 and are directly put into a handling room (not shown) for threshing and sorting.

In a normal flat field, when the harvesting and threshing operation is continuously performed by the combine 1 as described above, the mowing device 6 is held at the height of the normal operation position. The signals are input to the control device 100 from the cutting position detection sensor S9 and the ultrasonic sensor S10.
Then, the front grain culm sensor S1 and the rear grain culm sensor S2
The short culm sensor S3 detects and inputs a cereal culm whose cereal culm length is equal to or greater than a specified value.

The handling depth adjusting device 26 receives detection information from the tip sensor S4 and the stock sensor S5 into the control device 100, and controls the handling depth adjusting device according to an operation signal output from the control device 100 based on the information. Actuator M1
Is controlled and the handling depth is automatically adjusted via the connecting rod 27. In this case, the CPU 101 determines that the position where the tip position of the transported grain culm passes between the tip sensor S4 and the stock sensor S5 is the position of the most suitable handling depth, and the handling depth adjusting device 26 Adjustment control is performed so that the adjustment position is adjusted. Usually, the adjustment of the handling depth is performed only by the handling depth adjustment device 26, and the adjustment by the supply and transport device 30 is not required.

Next, when the combine 1 reaches the ridge of the field and shifts to the cutting of the headland, the operator operates the ridge to prevent the tip of the weeding tool 8 from colliding with the ridge rising at the edge of the field. Then, the switch S13 is turned on to extend the mowing elevating cylinder 13a manually, and the mowing apparatus 6 is raised to a predetermined position, and the process proceeds to the high cutting work of the grain culm.

When the ridge-side switch S13 is turned ON, the control device 100 stops controlling the adjustment of the handling depth based on the detection information from the tip sensor S4 and the stock sensor S5.
Based on the detection information from the front grain culm sensor S1 and the short culm sensor S3, the handling depth adjusting device 26 and the supply / transport device 3
0 is adjusted and controlled.
