  With conventional combines, the driver's seat is attached to open and close the engine bonnet, so it tends to be difficult to open and close because it is heavy and has a large dynamic inertia or is bulky and difficult to handle.

  The present invention provides a combine that can easily open and close an engine bonnet while being able to open around an engine and a radiator over a wide range.

The combine according to the present invention is:
An engine bonnet that accommodates an engine and a radiator for cooling the engine located on the laterally outer side of the engine body, and supports the driver's seat, is provided at the lower part of the driving unit.
The engine bonnet includes a front wall portion that covers the front of the engine and the radiator, a top plate portion that covers the engine and the radiator and supports the driver's seat, and a dust-proof case that covers a lateral side of the radiator body. And comprising
The engine bonnet includes an outer divided front wall portion that constitutes the fuselage lateral outer portion of the front wall portion, an outer divided top plate portion that constitutes the fuselage lateral outer portion of the top plate portion, and the dust proof An openable first split bonnet portion that is swingably opened and closed around an open / close axis of the machine body that is positioned below the dust-proof case portion and is swingably opened and closed, with each of the case portions, and the front wall Each of the inner divided front wall portion constituting the fuselage lateral inner side portion of the vehicle body and the inner divided top plate portion constituting the fuselage lateral inner side portion of the top plate portion and supporting the driver seat. A combine-type second divided bonnet portion fixedly supported by the fuselage frame.

  According to this configuration, among the engine bonnet, the second split bonnet part that supports the driver's seat is fixedly supported by the fuselage frame, and only the first split bonnet part that does not have the driver's seat is opened and closed. Compared to opening and closing, it is light and difficult to attach a large dynamic inertia, or it is easy to handle because it is small and easy to handle. When the first divided bonnet portion is opened, not only the dustproof case portion but also the outer divided front wall portion and the outer divided top plate portion are opened, so that the engine and the radiator can be opened over a wide range.

  Therefore, the engine and the radiator can be opened over a wide range, so that not only the inspection of the engine and the radiator can be easily performed, but the engine bonnet can be easily opened and closed.

  In the present invention, the state is switched between a connected state in which the first divided bonnet part and the second divided bonnet part are connected, and a released state in which the connection between the first divided bonnet part and the second divided bonnet part is released. An operable connecting tool, the connecting tool being capable of connecting the outer divided top plate portion and the inner divided top plate portion, and in the closed state of the first divided bonnet portion, the driver seat It is preferable to be located in a space between the top plate part and the top plate part.

  According to this configuration, when driving, the coupling tool is located below the driver seat and is unlikely to become an obstacle, and when opening and closing the first split bonnet part, put a hand between the driver seat and the top plate part. Thus, the connecting tool can be easily operated.

  In the present invention, the outer side inner edge of the outer divided top plate portion enters the inner side of the fuselage more than the outer lateral end of the driver seat in the closed state of the first divided bonnet portion, and the outer side The fuselage lateral inner edge at the lower part of the front split wall is positioned on the laterally inner side of the fuselage lateral inner edge of the outer divided top plate part in the closed state of the first split bonnet part, and outside The inner inner edge of the upper part of the divided front wall portion is inclined from the front edge of the fuselage transverse inner edge of the outer divided top plate portion toward the upper end of the fuselage transverse inner edge of the outer divided front wall portion. It is preferable to do so.

  According to this configuration, the lateral width of the outer divided top plate is larger than that of the lateral inner edge of the outer divided top plate and the lateral outer edge of the driver seat at the same position in the lateral direction of the fuselage. Compared to the fact that the inner side edge of the fuselage at the lower part of the outer split front wall and the inner side edge of the outer split top plate are located at the same position in the lateral direction of the fuselage. The width of the wall can be increased. Even if the lateral width of the outer divided top plate portion and the lateral width of the outer divided front wall portion are widened, the outer divided front wall portion becomes the driver's seat due to the inclination of the inner edge at the upper portion of the outer divided front wall portion. The first divided bonnet portion can be opened without hitting.

  Accordingly, when the first divided bonnet portion is opened, the engine and the radiator can be widely opened.

  In the present invention, in the closed state of the first divided bonnet portion, the driver seat is located over the first divided bonnet portion and the upper portion of the second divided bonnet portion, and the outer side It is preferable that the airframe lateral inner edge at the lower part of the divided front wall portion is located below the central portion in the lateral width direction of the driver seat.

  According to this structure, when the 1st division | segmentation bonnet part is opened, an engine room can be open | released in the range from the edge of the body lateral outer side to the downward location of the center part in the width direction of a driver's seat.

It is a side view which shows the whole combine. It is a side view which shows a drive part. It is a front view which shows the drive part in the closed state of a 1st division | segmentation bonnet part. It is a front view which shows the drive part in the open state of a 1st division | segmentation bonnet part.
