作業機に関する。[Detailed description of the invention] This invention has substantially one running wheel, and is spaced apart in the left and right direction from the front fuselage, which has a driving unit located forward of the ground-contacting part of the running wheel. A rear fuselage having a plurality of ground-contacting parts is connected to the rear fuselage with a plurality of ground-contacting parts separated from each other so as to be relatively rotatable left and right around a vertical axis, and a steering handle is provided for relatively rotating the two bodies to turn the fuselage. Regarding riding working machines such as certain rice transplanters.

傾いたり、転倒するなどの危険性があつた。 In a riding work machine having such a configuration, when traveling straight ahead, the plurality of ground-contacting parts of the rear body are pressed against the ground by running reaction force, and the running wheels of the front body and the ground-contacting part of the rear body balance the body against the ground. However, when the aircraft turns, the running speed is generally reduced, so the pressure on the rear ground contact area due to the running reaction force is reduced, and the load bearing rate of the running wheels is reduced. Not only does this increase significantly, making the ground support in the longitudinal direction of the aircraft unstable, but also with the turning operation of the handle,
The front and rear fuselage, which have large moving parts, are bent in a dogleg shape when viewed from above, and the center of gravity of the aircraft moves inward in the direction of the aircraft's rotation, creating the risk of the aircraft tilting or overturning. The sex was hot.

持可能な機構を設けてあることを特徴とする。 The present invention can reliably prevent the aircraft from tilting or overturning when turning as described above without increasing the weight of the aircraft.Furthermore, by utilizing this configuration, it is possible to securely prevent the aircraft from tilting or overturning when turning. The purpose of this system is to make it possible to easily perform backward-facing work while seated in a comfortable posture. A mechanism is provided for forcibly moving the driver's seat in a lateral direction different from the aircraft turning direction, and during this driver's seat forced movement mechanism, the driver's seat is allowed to move laterally within a certain range, and the steering wheel is moved beyond a certain level. In addition to providing flexibility to move the driver's seat in conjunction with the steering operation,
The vehicle is characterized by being provided with a mechanism capable of fixing and holding the driver's seat at a central position of its lateral movement range.

中での運転席のふらつきに起因する機体の蛇行を
防止して、直進作業を安全に行なえるに至つた。 That is, when the aircraft turns, by forcibly moving the driver's seat laterally, which is different from the direction of the aircraft turning, in conjunction with the steering operation of the handle above a certain level, the load bearing rate by the front running wheels is reduced as described above. Although it is unavoidable that this increase will make the ground support of the aircraft unstable, it is possible to sufficiently prevent the center of gravity of the aircraft from moving inward in the turning direction by the weight of the driver. Since it is possible to stabilize the weight balance in the direction, for example, compared to the case where a balance weight with a large weight is moved in the left and right direction to balance the left and right balance, the weight of the machine can be significantly increased. It is possible to avoid dangers such as tilting and overturning when the aircraft turns. Moreover, the above-mentioned flexibility provided in the driver's seat forced movement mechanism makes it possible to avoid deterioration in comfort and maneuverability caused by forced lateral movement of the driver's seat when correcting a meandering line while driving straight ahead. However, when working rearward while seated in the driver's seat, such as replenishing seedlings, the orientation of the driver's seat can be changed freely within the range of flexibility mentioned above, so it is possible to avoid the unreasonable posture of twisting the upper body backwards. There is no need to take a seat, and this kind of work facing backwards can be easily done in a comfortable posture. Furthermore, since the driver's seat is equipped with a mechanism that can be fixed and held at the center of its lateral movement range, it is possible to prevent the meandering of the aircraft caused by the driver's seat wobbling during straight-ahead travel, allowing safe straight-ahead work. I was able to do it.
