JP 2000-92962 A (paragraphs [0025], [0026], FIGS. 1, 2 and 3)

In the harvesting machine described above, the front-rear length of the traveling machine body becomes smaller as the control tower is moved rearward, and the front-rear length of the entire harvesting machine can be shortened.
In this case, in the conventional driving part structure, since the space between the control tower and the driver's seat is narrow, the space around the foot is also narrowed, and the comfortability tends to be deteriorated.

  The objective of this invention is providing the operation part structure of the harvester which can bring a control tower to the back side, making the habitability of an operation part good state.

The first aspect of the present invention is a harvester operating part structure comprising a control tower provided in front of a driver seat and a steering operation tool protruding upward from the control tower.
The height of the upper surface of the control portion of the control tower that supports the steering operation tool is higher, and the height of the upper surface of the side portion of the control tower that is located on the side of the control tower than the control portion. Configure the lower,
Provided below the control portion of the control tower is a foot notch that forms a gap connected to the operation unit floor ,
Place a brake pedal in the gap,
The foot notch is formed in a state where the entire brake pedal is visible from the foot notch when viewed from the front of the body .

  According to the configuration of the first aspect of the present invention, even if the distance between the driver's seat and the control tower is narrowed by moving the control tower to the rear side, the leg is seated with the legs extended as much as possible by inserting the legs into the gap. Can do.

Providing a foot notch portion below the steering portion makes it easier to suppress the swinging movement of the steering operation tool.
In other words, when the foot notch is provided below the steering part, the height of the steering part is increased by the length corresponding to the length in the vertical direction of the foot notch or a length close thereto, A size capable of accommodating an operation mechanism that links the steering operation tool to the operation target device can be secured in the control portion. Then, the arrangement height of the upper surface of the control portion increases. Regardless of the change in the height of the steering part, the support part of the steering control tool is placed at an easy-to-operate placement height, which shortens the protruding length of the steering control tool from the steering part. It becomes easy to suppress the shaking movement of the direction control tool.

  Therefore, the driver's habitability is improved and the control tower is moved to the rear side to shorten the front and rear length of the traveling aircraft and to further suppress the swinging movement of the steering operation tool. Thus, a harvesting machine that can be easily operated and operated can be obtained from the operability aspect of the steering operation tool and the longitudinal length of the traveling machine body.

According to the configuration of the first aspect of the present invention, the height of the upper surface of the control tower at the control portion is increased, and the upper surface of the control portion of the control tower is located on the lateral side of the control tower. from a low placement height Rukoto, even higher placement height steering portion, the arrangement height of the lateral side portion so as to be able to take a sitting posture that issued the kneecap above the lateral side portion Can be lowered.
Therefore, even when the traveling body is made compact in the front-rear length, it is easier not only to put the foot into the gap below the maneuvering part but also to extend the leg as much as possible by extending the knees above the side part. It is possible to obtain a harvesting machine that can sit in a simple posture and work more easily and lightly.

According to the configuration of the first invention, since the brake pedal is disposed in the gap, the brake pedal can be operated with a posture in which the legs are put in the gap and the legs are extended.
Therefore, even when the traveling body is reduced in length in the front-rear length, a harvester that can be easily and lightly operated and operated not only from the viewpoint of the seating posture but also from the aspect of the operation posture of the brake pedal can be obtained. .

In the second aspect of the invention, the brake pedal is arranged in the fuselage side in the lateral direction of the fuselage from the lateral side end of the driving unit floor outside the fuselage.

In the third aspect of the invention, the brake pedal is arranged in the fuselage in the lateral direction of the fuselage and on the inner side of the side of the outer side of the control tower.

In the fourth aspect of the present invention, a rising portion that rises from the operation unit floor and a laterally outward rising inclined portion that inclines from the upper end of the rising portion toward the upper lateral side of the fuselage are formed on a lateral side edge outside the fuselage of the control tower. In addition, by forming the lateral side edge into a stepped edge that enters the inside of the fuselage on the lower side of the control tower, the foot notch portion is configured.
In the fifth aspect of the present invention, the foot notch is formed so that the upper end of the rising portion is positioned above the upper end of the brake pedal.
According to the sixth aspect of the present invention, an insertion hole for a brake pedal that enables deployment of the brake pedal in the gap is provided in an outer portion of the front end portion of the operation unit floor in a lateral direction of the aircraft. It was formed so as to overlap the rising part of the control tower in a side view of the aircraft.

In the seventh aspect of the invention, the brake pedal is fixedly equipped with a rod that protrudes forward from the air gap through the gap.
