"Problems to be solved by the invention" In the prior art, since the threshing unit and the grain take-out unit are arranged side by side, if the weight of the grain take-out unit changes during work, the machine weight center moves to the left and right, and the balance is lost. Since the driver's seat and the engine are provided offset to one side of the fuselage, there is a problem that the balance of the fuselage is likely to be deteriorated due to an increase in the weight of the one side of the fuselage due to the boarding of an operator. In addition, since the engine cooling air is discharged to a low position between the threshing unit and the grain take-out unit, it is easy to use the exhaust heat, such as the engine heating the upper surface of the handling room of the threshing unit with the cooling air and dehumidifying. There are also problems such as inability to obtain.

"Means for solving the problem" However, in the present invention, a threshing unit in which a handling drum is installed is installed above the left and right traveling crawlers, and a grain tank is mounted on the upper side of the threshing unit, and the threshing unit upper surface And a bottom surface of the grain tank and a long exhaust passage in the front-rear direction, and a driver's cab and an engine are arranged right and left at the front of the threshing unit, and the cooling air of the engine is taken into the front of the exhaust passage and exhausted. An exhaust fan for exhausting from the rear part of the road is provided.

"Operation" Therefore, a grain tank is provided above the threshing section between the left and right traveling crawlers, so that even if the weight of the grain tank changes during work, the left and right balance of the aircraft can be maintained well, and operation is performed in front of the threshing section Since the compartment and engine are separated to the left and right, changes in the left-right balance of the machine due to the operator's boarding can be easily reduced, and the engine cooling air is discharged because the upper surface of the threshing unit and the bottom of the grain tank form an exhaust path. Since a special guide to guide is unnecessary, and the upper surface of the threshing unit and the bottom of the grain tank are heated by the engine cooling air, dehumidification of the handling room in which the handling cylinder is installed and dehumidification of the grain tank bottom can be easily performed,
It is possible to easily reduce adhesion and accumulation of dust in a closed cold space around the upper side of the handling cylinder and a closed cold space below the inside of the grain tank.

5) Threshing section (4) between left and right traveling crawlers (2) (2) with exhaust fan (48) exhausted from the rear
Since the grain tank (7) is provided on the upper side, even if the weight of the grain tank (7) changes during operation, the left-right balance of the aircraft can be maintained well, and the operator's cab (11) in front of the threshing unit (4) And the engine (13) are distributed to the left and right, making it easy to reduce changes in the left-right balance of the aircraft due to the boarding of workers,
Since the exhaust channel (35) is formed by the top of the threshing unit (4) and the bottom of the grain tank (7), a special guide for guiding the cooling air to the engine (13) is not required, and the engine (13)
Threshing unit (4) upper surface and grain tank (7) by cooling air
Since the bottom surface is heated, dehumidification of the handling room in which the handling cylinder (5) is provided and dehumidification of the bottom of the grain tank (7) can be easily performed. It is possible to easily reduce adhesion and accumulation of dust in a closed cold space below the inside of the tank (7).
