The control section C contains control switching means C1 and circulating control means C2. The control switching means C1 controls the operation of the multi-steering lever 56 when the push button switch 57 is turned on. The detection signals of the rotary switches 56a and 56b for detecting the left and right operation positions are transmitted to the traveling control means C2.
When the lever 56 is operated left and right, the circling control means C2 responds to the left and right operation positions of the lever 56 based on the fact that the push button switch 57 is turned on.

Next, the operation of this embodiment will be described.

FIG. 3 shows a main flow in the control section C. The main flow includes an initial setting subroutine S1, a horizontal control subroutine S3, and a steering control subroutine.
It is composed of the chin S5 and the like.

The circulating control of the combine according to this embodiment will be described.

In the harvesting operation in the field of the combine 1, for example, in a wetland, during automatic horizontal control, the operator moves the multi-steering lever 56 to a predetermined position, for example, in the left operation position so as to rotate the combine 1. When the tilting operation is performed, the lever 5
Based on the operation of 6, the left side clutch is controlled to be disengaged, and the traveling body is turned left. At this time, when the push button switch 57 is turned on, the control section C stops the horizontal automatic control based on the signal of the switch 57, and the control switching means C1.
Transmits a signal from a rotary switch 56a for lowering the traveling body left, which detects the left operation position of the lever 56, to the traveling control means C2. Based on a switch 56a signal from the switching means C1, the left side clutch is disengaged and controlled, and the solenoid valve 61a is controlled to operate the left hydraulic cylinder 22L to operate the traveling machine body 3 in the lower left direction.

The same applies to the case where the multi-steering lever 56 is tilted to the right operation position. As described above, the inclination of the combine 1 is controlled such that the inside of the traveling body 3 in the turning radial direction is located below the outside.

Next, an embodiment in which the above-described embodiment is partially modified will be described.

In the embodiment described above, the combine 1
For example, when the mowing work is circulating in a wet field, the left and right clutches are controlled to be disengaged based on the left and right operations of the multi-steering lever 56, and the inclination is controlled so that the inside of the traveling machine body 3 in the turning radial direction is lowered to the outside. I have. However, when the combine 1 travels on a hard road surface or the like,
When the traveling body 3 turns, the traveling stability of the traveling body 3 may be reduced and large pitching may occur. In such a state, the outside of the traveling body 3 in the turning radial direction is lowered with respect to the inside. The running stability increases when the inclination is performed.

Therefore, as shown in FIGS. 5 and 6, the side operation panel 58 is provided with a changeover switch 65 for switching between the left hydraulic cylinder and the right hydraulic cylinder.
When the multi-steering lever 56 is operated to the left operation position, the push button switch 57 is turned on, and the changeover switch 65 is turned on, the switch 65 is turned off.
N, based on the left operation position of the lever 56,
The left side clutch is controlled to be disengaged, and the solenoid valve 61b is controlled so that the right hydraulic cylinder 22R is operated to operate the traveling machine body 3 in the lower right direction, while the lever 56 is operated to the right operation position. When the push button switch 57 is ON, the changeover switch 65 is ON.
When the switch 65 is turned on, the right side clutch is controlled to be disengaged in accordance with the right operation position of the lever 56, and the left hydraulic cylinder 22L is operated to lower the traveling body 3 to the left. The traveling control means C3 for controlling the solenoid valve 61a so as to operate the solenoid valve 61a is provided. C1 is control switching means.

Therefore, the multi-steering lever 5
6 is operated, for example, to the left operation position, and based on that the push button switch 57 is turned on, the left side clutch is controlled to be disengaged, and the solenoid valve 61a is controlled to operate the left hydraulic cylinder 22L. When operating and operating the traveling body 3 in the lower left direction, the switch 65
Is turned on, based on the signal of the switch 65, the traveling control means C3 of the control section C controls the disengagement of the left side clutch in accordance with the left operation position of the lever 56 and the solenoid valve 61b. , The right hydraulic cylinder 22R is operated to operate the traveling body 3 in the lower right direction.

The same applies when the multi-steering lever 56 is operated to the right operation position.

As described above, the multi-steering lever
When the push-button switch 57 is turned on at the time of the left-right operation of the switch 56, the left-right hydraulic cylinder switching switch 6
When the switch 5 is turned on, based on the switch 65 being turned on,
The left and right hydraulic cylinders 22L and 22R are switched and operated,
Since the inclination control is performed so as to switch the left and right lowering directions of the traveling body 3, the multi-steering lever 56 including the push button switch 57 and the operation of the changeover switch 65 can be operated when the combine 1 rotates, regardless of the hardness of the field and the road surface. Thereby, the turning of the traveling machine body can be performed simply and surely.

Further, the tilt control of the traveling body will be described.

In the above embodiment, the case where the push button switch 57 is pressed when the multi-steering lever 56 is operated to the left and right operation positions has been described. Hereinafter, a case will be described in which the multi-steering lever 56 is operated to the left and right operation positions when the push button switch 57 is pressed while the operation position of the multi-steering lever 56 is in the neutral position.

As shown in FIG. 7, the control section C contains a control switching means C5 and an inclination control means C6. The control switching means C5 has a multi-steering lever 56 in a neutral position and a push button. When the lever 56 is operated left and right while the switch 57 is turned on,
The signals from the tally switches 56a and 56b are transmitted to solenoid valves 61a and 61b for operating the left and right hydraulic cylinders 22L and 22R.
The control signal is transmitted to the inclination control means C6 so as to control 61b. When the operation position of the lever 56 is in the neutral position, the inclination control means C6 sets the push button switch 57 to the O position.
N, when the lever 56 is operated left and right, the switches 56a and 5
6b, the left and right hydraulic cylinders 22L, 22L
The solenoid valves 61a and 61b are controlled so that R is operated in the left and right lowering direction of the traveling machine body 3.

As shown in FIG. 4, the operator operates the multi-steering lever 56 while the combine 1 is in the horizontal automatic control mode.
The push button switch 57 is in the neutral position.
Is turned on (S7), and when the lever 56 is, for example, predeterminedly operated to the left operation position (S8), the rotary switch 5 is turned on.
6a detects the tilt angle of the lever 56 and sends this detection signal to the control unit C. Then, the control section C stops the horizontal automatic control, and the control switching means C5 sets the rotary switch 56.
is transmitted to the inclination control means C6, and based on the detection signal of the switch 56a, the inclination control means C6 controls the solenoid valve 61a for lowering the traveling machine body left, operates the left hydraulic cylinder 22L, and travels. The airframe is operated in the lower left direction (S9). In addition, multi steering lever-5
6 is operated to the right operation position (S8), the rotary switch 56b detects the tilt angle of the lever 56 and transmits this detection signal to the control unit C. Then, the control switching means C5 of the control unit C transmits a detection signal of the rotary switch 56b to the inclination control means C6, and the inclination control means C6
Based on the detection signal of the switch 56b, the traveling machine right lowering solenoid valve 61b is controlled and the right hydraulic cylinder 22
Activate R to operate the traveling body in the downward right direction (S
10).

On the other hand, when the push button switch 57 is in the OFF state (S7) and the lever 56 is in the neutral position (S8), it is determined whether or not the horizontal automatic switch 60 has been operated and turned ON. That is, it is determined whether or not the pulse is at the rising position (S11). If the horizontal automatic flag is reset at the rising position (S12),
The horizontal automatic flag is set (S14). If the horizontal automatic flag is set (S12), the horizontal automatic flag is reset (S14). If the horizontal automatic flag is set (S15), automatic horizontal control is performed (S16).

Thus, the multi-steering lever 5
If the lever 56 is operated left and right while the switch 57 is turned on while the switch 6 is in the neutral position state, the horizontal automatic control is stopped and the traveling body 3 is moved in accordance with the left and right operation positions. Can be controlled, so that a tilt manual operation lever is not required and cost can be reduced.
