DESCRIPTION OF THE PREFERRED EMBODIMENTS [First Embodiment] FIG. 1 is a right side view of a combine as an example of a harvester according to the present invention, and shows a traveling machine body equipped with a pair of left and right traveling devices 1, 1 of a crawler type. A cutting unit 3 that cuts and transports the planted grain culm to the front of the hull 2 is movably connected to the front part of the traveling machine 2, and a threshing process for threshing the harvested grain culm from the cutting unit 3 is provided on the upper left side of the traveling machine 2. The vehicle includes a riding section 5, an engine 6, and a Glen tank 7 for storing threshing grains. Further, the Glen tank 7 is provided with an unloader 8 as a grain discharging device for discharging the thresh grains stored in the Glen tank 7 to a carrier such as a transport vehicle or another storage container. I have.

In the combine, as shown in FIG.
A horizontal adjustment mechanism 9 for adjusting the horizontal attitude of the traveling machine body 2 to a horizontal attitude, and a mowing so that the handling depth in the threshing unit 4 is substantially constant irrespective of the culm length of the mown harvested culm. Depending on the handling depth adjusting mechanism 10 for transferring the grain culm to the feed chain of the threshing unit 4 and the volume (amount) of the threshing material deposited on a chaff sheave (not shown) constituting the sorting unit of the threshing unit 4. The opening degree adjustment mechanism 11 and the like for adjusting the mesh between the chaff flip plates of the chaff sheave so as to exert the proper grain sorting performance by means of the chaff sheave are provided.

Each of the left and right traveling devices 1, 1 is shown in FIG.
As shown in FIG. 5, a movable track frame 15 having a plurality of idler wheels 13 supported on a fixed track frame 12 fixed to the traveling machine body 2 and having a tension roller 14 supported thereon via an elevating link mechanism 16. A crawler belt 19 is wound around the driving sprocket 18 supported by the transmission case 17 and fixed to the traveling body 2 and the plurality of idler wheels 13 and tension wheels 14. Have been. The lifting link mechanism 16 includes a front link member 20 including an upper front arm 20a and a lower front arm 20b, a rear link member 21 including an upper rear arm 21a and a lower rear arm 21b, a connecting rod 22, and a lifting cylinder. 23. The front and rear link members 20 and 21 are pivotally supported by the fixed track frame 12 and have the lower front arm 20 b and the lower rear arm 2.
The tip of 1b is pivotally supported by the movable track frame 15, the tips of the upper front arm 20a and the upper rear arm 21a are connected by a connecting rod 22, and the lifting cylinder 23 is connected to the tip of the upper rear arm 21a. ing. Therefore, when the elevating cylinder 23 is driven to extend, the front and rear link members 20 and 21 rotate counterclockwise in the drawing, and the lower front arm 20b and the lower rear arm 21b swing downward. As the movable track frame 15 descends along with this, the contact surface of the crawler belt 19 descends. Also, if the lifting cylinder 23 is shortened, the front and rear link members 20 and 21 rotate clockwise in the drawing, and the lower front arm 20b and the lower rear arm 21b swing upward. As the movable track frame 15 moves up, the contact surface of the crawler belt 19 rises.

That is, for example, when there is a height difference between the traveling surface on which the right traveling device 1 travels and the traveling surface on which the left traveling device 1 travels, or a large amount of threshing kernels is stored in the Glen tank 7. When the right traveling device 1 sinks into its traveling surface due to the left and right load balance of the traveling vehicle body 2 being lost, the crawler belts 1 of the left and right traveling devices 1 and 1
9 is located at the same distance from the traveling body 2, the traveling body 2 is tilted in the left-right direction, and the traveling body 2 is tilted.
There is a possibility that the threshing process is changed or the threshing process is shifted to one end in the left-right direction of the sorting unit disposed in the threshing unit 4 so that it is not possible to perform an appropriate sorting process. Each of the lifting cylinders 23 of the traveling devices 1 and 1 is separately driven, and each of the ground surfaces of the left and right crawler belts 19 is properly adjusted with respect to the traveling machine 2 until the traveling machine 2 is in a horizontal posture in the left-right direction. By changing the traveling body 2 to the separated position, the posture of the traveling body 2 in the left-right direction can be adjusted to a horizontal state. That is, the horizontal adjustment mechanism 9 is configured by the left and right traveling devices 1 and 1 configured as described above.

From the engine 6, the left and right traveling devices 1, 1
Although not shown, the transmission system to the drive sprockets 18, 18 turns the traveling body 2 by giving a speed difference to the traveling speeds of the continuously variable transmission, the forward / reverse switching device, and the left and right traveling devices 1, 1. A turning device or the like for driving is interposed.

The forward / reverse switching device is disposed in the transmission case 17, and transmits the output from the continuously variable transmission to the driving sprockets 18, 18 of the left and right traveling devices 1, 1 as forward driving power. A reverse state in which the output of the continuously variable transmission is transmitted to the driving sprockets 18 of the left and right traveling devices 1 and 1 as reverse driving force, and the output of the continuously variable transmission is the driving sprocket 1 of the left and right traveling devices 1 and 1.
And a neutral state in which the signal is not transmitted to the control units 8 and 18. The forward / reverse switching device is operated to switch between a forward state, a neutral state, and a reverse state based on a forward / backward swing operation of a main shift lever 24 described later, and swings the main shift lever 24 forward. The state in which the moving operation is performed is a forward state, the state in which the main shift lever 24 is swinging rearward is a reverse state, and the state in which the main shift lever 24 is erected at the center in the front-rear direction is a neutral state. Further, the main transmission lever 24 is linked to a continuously variable transmission, and the main transmission lever 2
The more the rocker 4 is operated to swing forward from the neutral state and the more the main shift lever 24 is rocked backward from the neutral state, the higher the traveling speed of the left and right traveling devices 1, 1 becomes. Is configured.

The turning device includes the transmission case 1
7, the rotation speed of the driving sprocket 18 of the left traveling device 1 and the rotation speed of the driving sprocket 18 of the right traveling device 1 are changed based on the left and right swing operation of the steering operation lever 25 described later. A mechanism for generating a difference, in other words, a mechanism for generating a speed difference between the traveling speeds of the left and right traveling devices 1, 1 is provided. When the steering operation lever 25 is held in a neutral standing state, the left and right traveling The traveling speeds of the devices 1 and 1 become the same, and the traveling body 2 goes straight ahead. Then, when the steering operation lever 25 is swung to the left from the neutral state, a speed difference occurs between the left and right traveling devices 1 and 1 in a state where the traveling speed on the right traveling device 1 side is high, and the traveling body 2 is moved. When the steering operation lever 25 is swung to the right from the neutral state to the left turning state in which the vehicle turns left, the left and right traveling devices 1 and 1 move at a high speed when the traveling speed on the left traveling device 1 is high. A difference occurs, and the traveling body 2
Is turned rightward to turn right. Further, the more the swing operation of the steering operation lever 25 is performed, the greater the difference between the traveling speeds of the left and right traveling devices 1 and 1 is, so that the turning radius is reduced accordingly.
