[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine for continuously cutting and threshing grain culms.

[0002]

2. Description of the Related Art Conventionally, an engine is disposed below an operator's seat via an engine cover, a cooling air path cover is mounted outside the engine cover machine, and a cooling air path cover is provided outside the operator's seat and a paddle stand behind the operator's seat. There was a technology to attach the auxiliary paddy cradle so that it could be undulated.

[0003]

In the prior art, it is desired that the cooling air path cover be extended outside the machine as much as possible and that the auxiliary paddy pad be formed as wide as possible on the right and left sides. However, due to the overhang of the cooling air path cover, the wide auxiliary paddy pad is protruded to the outside of the machine and stored upright. It will be easier. Therefore, there was a technology to divide the auxiliary paddy cradle in the left and right width direction and freely bend it to prevent hooking of uncut culms, but the number of components and weight of the auxiliary paddy cradle increased,
There were problems such as the simplification of the structure of the auxiliary paddy pad and reduction of the production cost could not be easily performed.

[0004]

According to the present invention, an engine is disposed below a driver's seat via an engine cover.
Attach the cooling air path cover to the outside of the engine cover machine and attach the auxiliary paddy cradle on the outside of the driver seat and the paddle cradle behind the driver seat so that it can be raised and lowered. Formed by an inclined surface that narrows the lower side of the cooling air path cover to the inside of the machine,
The auxiliary paddy cradle can be stood up and stored facing the inclined surface below the cooling air path cover, and the auxiliary paddy cradle is stored on the inboard side of the machine to make it easier to overhang the auxiliary paddy cradle. It is possible to easily reduce the cost and weight by preventing the catching and pushing down of the uncut culm by the auxiliary paddy cradle and simplifying the auxiliary paddy cradle structure, and at the lower side of the cooling air duct cover. Since the outside air sucked upward is guided to the inside of the lower machine by the inclined surface, simplification of the cooling air path and improvement of the cooling air supply function can be easily achieved.
