Description

[Detailed Description of the Invention] The present invention relates to a structure of an operating column section of a driving section in a combine harvester.

Conventionally, a combine has a reaping section on the left side of the front and a driving section on the right side of the front, a threshing section behind the reaping section, a sorting section below it, and a paddy storage section behind the driving section. A running section is provided at the bottom of the machine, and while running on the running section, the grain culms harvested at the reaping section are threshed at the threshing section, and the grains are sorted and collected at the sorting section. At this time, the operation column section of the driving section is closed by the front side wall, so that the front lower part of the driving section is blocked by the front side wall. During reaping work, the operator must lean forward to visually check the reaping section located on the left front and lower side and the state of the grain culm being raised. This visual recognition work was extremely inconvenient for the operator.

In this invention, the driving section and the reaping section, which is located to the side of the driving section and is movable up and down, are separated by a bulkhead, and a support is erected on the outside of the front of the floor of the driving section. Then, the horizontal shaft is suspended between the upper part of the support and the separation, and the lower end of the left/right steering clutch lever is fitted to the horizontal shaft, so that it is installed at the front end of the reaping part from the driving part. By configuring a gate-shaped operation column section with an open space where the grass dividing board can be seen, visibility of the cutting section and the front and downward direction is good, and safe and reliable operation is achieved. It is an object of the present invention to provide a structure for an operation column part of a driving part in a combine harvester.

While carefully checking the series of mowing operations such as pulling up grass and mowing,
It allows work to be carried out reliably and safely.

According to the present invention, the reaping section and the driving section are separated by a partition wall, a support is erected on the outside of the front part of the floor of the driving section, and a horizontal shaft is mounted between the support and the separating section. By fitting the lower end of the left/right steering clutch lever onto the shaft, an operating column is formed in which the front of the operating section is open, allowing the operator to easily check the front of the machine and also allow the operator to reap through the space. Because it is possible to check the grass dividing plate of the front part and the front and lower direction, it is easier to drive compared to the conventional model where the front part of the driving part is closed. There is no need to lean forward, and the driver can operate the vehicle in a comfortable position. In addition, this space provides ample legroom for the driver, resulting in excellent comfort, and the foot pedal provided at the foot of the vehicle is easy to operate, resulting in excellent operability. As a whole, although the structure is simple, visibility in front of the reaping section is improved, and work efficiency is significantly improved.

In addition, since the present invention separates the driving section from the reaping section, which is movable up and down, by a bulkhead, the operator will not be caught in the rotating reaping section, and will always be safe. Reaping work can be done in this condition.
