Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine drive section structure including a control tower located in front of a driver's seat and a side cover for covering a lateral side of a living space of the drive section on the side of a mowing section.

[0002]

2. Description of the Related Art Conventionally, in the above-mentioned combine, by providing an operation panel section in a control tower, it is easy to see the instruments and lamps for displaying the load condition of the engine or notifying that the grain tank is full. It was possible to equip it with.

[0003]

Conventionally, since it has been necessary to provide a space for installing an operation panel portion or the like in the control tower, the size of the control tower in the front-rear direction becomes large especially at the upper end side. Was there. As a result, if the control tower is prevented from projecting forward, the control tower is less likely to become an obstacle and it is easier to see ahead, but in this case, the distance between the control tower and the driver's seat becomes narrower, and The living space was getting smaller. The object of the present invention is to make it possible to install instruments and lamps so that the size of the control tower in the front-rear direction can be made as small as possible and the visibility of the mowing part etc. does not deteriorate as much as possible, and that instruments and lamps can be easily seen. To provide a simple combine driving section structure.

[0004]

The constitution, action and effect of the invention according to claim 1 are as follows.

[Structure] In the structure of the combiner's operation part, which includes a control tower located in front of the driver's seat and a side cover for covering the side of the living space of the operation part on the side of the mowing part,
An operation panel is arranged above the front end side of the side cover at a position separated from the control tower, with a space between the operation panel and the side cover.

[Operation] If the above-mentioned instruments and lamps are necessary, they are attached to the operation panel, and the operation panel is located at a position separated from the operation tower, so that the operation tower is provided with the operation panel. It is possible to equip instruments and lamps while suppressing the size of the control tower in the front-rear direction as much as possible without having to provide space for it. Moreover, because the operation panel is located above the front end of the side cover and there is a gap between the operation panel and the side cover, the instruments and lamps attached to the operation panel are easy to see. In addition to being supported by the arrangement, the cutting portion and the like are supported in a state where they are unlikely to become an obstacle so that they can be seen through the gaps and the like relatively easily.

[Effect] Therefore, instruments and lamps can be attached to the operation panel so that they can be easily seen. On the other hand, we were able to see the reaping part relatively easily from the distance between the operation panel and the side cover, making it easier to work. In addition, the size of the control tower in the front-rear direction was relatively small, and the front view was improved and the driver's living space was made as wide as possible to facilitate maneuvering and getting on and off.

The structure, operation and effect of the invention according to claim 2 are as follows.

[Structure] In the structure of the invention according to claim 1, the display direction of the operation panel can be changed.

[Operation] Even if the position of the eyes changes due to sitting or driving while standing or driving, or the driver changes, by changing the display direction of the driving panel accordingly You can adjust the lamps so that you can see them easily.

[Effect] Whether the driver is seated or standing, the display on the operation panel is easy to see even if the driver changes, and it is possible to drive appropriately so that there is no error or delay in operation or response. .

The structure, operation, and effect of the invention according to claim 3 are as follows.

[Structure] In the structure of the invention according to claim 1 or 2, the operation lever guide is supported on the upper end side of the side cover, and the side cover is provided between the front end of the operation lever guide and the control tower. A gap is provided to form the gap between the operation panel and the operation panel.

[Operation] If the operation lever guide is provided in a state of being supported on the upper end side of the side cover, the operation lever is located near the side of the driver's seat and guided by the lever guide, so that the operation lever can be easily operated. Become. In this case, the front end of the operation lever guide should be brought into contact with or close to the control tower, and a line-of-sight gap should be provided between the operation lever guide and the operation panel so that the cutting section can be seen through the lower side of the operation panel. If enabled, the level of operation panel placement will be higher. In contrast,
The line of sight between the operation panel and the side cover is formed in the gap between the front end of the operation lever guide and the control tower, while the placement level of the operation panel is kept as low as possible.
Through the bottom of the operation panel, it is possible to see through the mowing part.

[Effect] Therefore, the operation lever can be provided near the side of the driver's seat in a state of being guided by the operation lever guide to facilitate the operation, and a space between the operation panel and the side cover is provided under the operation panel. In comparison, the level of the operation panel is relatively low, so that even if the user is seated or a relatively small driver, the operation panel is easy to see and it is possible to drive properly so that mistakes and delays in operation and response are unlikely to occur.

The structure, operation and effect of the invention according to claim 4 are as follows.

[Structure] In the structure of the invention according to any one of claims 1 to 3, a work light is attached to the operation panel.

[Operation] The operation panel is used as a support member and is equipped with a work light so that work can be performed while illuminating the mowing part and the like.

[Effect] It is easy to work by illuminating the mowing part and the like even in the evening. For that reason, the operation panel is used as a support member for the work light, which is advantageous in terms of structure and economy.
