JP 2004-34780 (paragraphs [0013], [0017], [0018], [0023], FIGS. 11 and 14)

  In what is shown in Patent Document 1, the engine bonnet and the driver's seat rotate around the axis of the self-propelled machine body so that the engine can be opened without any work obstacles above the engine. Then, the engine bonnet and the driver's seat need to be raised from a closed state to a high place, and the opening / closing operation tends to be heavy.

  When the technique disclosed in Patent Document 2 is adopted, when the engine is opened, the engine bonnet and the driver's seat are in a state that protrudes largely laterally outward from the self-propelled aircraft.

  An object of the present invention is to allow the engine bonnet and the driver's seat to be easily moved and operated while the engine can be opened upward without any obstacles. An object of the present invention is to provide a combine that can suppress the amount of protrusion outside the self-propelled aircraft.

In the first invention, in the combine provided with the driver seat located above the engine bonnet,
The engine bonnet and the driver's seat are disposed on the rear side of the self-propelled aircraft from the engine and on the side of the self-propelled aircraft inward of the outer end of the aircraft in the lateral direction of the engine. Around the driver's open shaft, the engine bonnet covers the engine in a closed state, and the engine bonnet and the driver's seat are located on the rear side of the self-propelled aircraft from the engine so that the engine is opened. It is configured.

  That is, the engine bonnet and the driver's seat are located on the rear side of the self-propelled aircraft with respect to the engine and on the side of the self-propelled aircraft with respect to the lateral side of the engine in the lateral direction of the self-propelled aircraft. The engine is rotated around the opening axis of the driving unit, and is opened to be located on the rear side of the self-propelled machine body relative to the engine to open the engine. As a result, the engine can be opened by moving the engine bonnet and the driver seat with the same or substantially the same arrangement height as that in the closed state. In addition, the engine bonnet and the driver's seat that are in the open state are positioned as far as possible on the rear side of the engine, and the engine can be opened while minimizing the amount of protrusion of the engine bonnet and the driver's seat from the self-propelled body to the outside.

  Therefore, according to the first invention, the opened engine bonnet and the driver's seat are located on the rear side of the self-propelled aircraft from the engine, and there are no obstacles such as the engine bonnet above the engine, so that the inspection work can be performed. While the engine can be opened in a state that is easy to perform, the engine bonnet and the driver's seat can be moved while maintaining the same or almost the same height as when the engine is closed. In addition, the amount of protrusion of the engine bonnet in the open state and the driver's seat to the outside of the self-propelled aircraft is reduced, and the engine bonnet or the like is less likely to be an obstacle to the work, and the inspection work and the like can be easily performed.

  According to the second aspect of the present invention, in the configuration of the first aspect of the present invention, the engine further includes a support frame that is swingably connected to a self-propelled machine body frame around an axis parallel to the operating unit opening axis. The free end side of the bonnet is slidably supported on the free end side of the support frame.

  That is, when the engine bonnet is opened and closed and rotated, the free end side of the engine bonnet slides on the support frame to apply an operating force to the support frame, whereby the support frame supports the engine bonnet while supporting the load. It swings on the bonnet and opens and closes the engine bonnet.

  Therefore, according to the second aspect of the present invention, the engine bonnet can be smoothly and lightly rotated as much as the load of the engine bonnet is supported by the support frame, and the opening and closing operation of the engine bonnet can be performed more lightly.

In the third aspect of the present invention, in the configuration of the first or second aspect of the present invention, the driving unit floor and the control tower located in front of the driver seat, and the side that partitions the inside and the outside of the driving unit on the lateral side of the driving unit floor. It has an operation panel located on the side of the side wall and the driver's seat,
The control tower, the lateral side wall, the operation panel, and the operation unit floor are rotatably supported with respect to the self-propelled body frame integrally with the engine bonnet around the operation unit opening axis.

That is, when the engine is opened by rotating the engine bonnet to the open state, the control tower, the side wall, the operation panel, and the operation unit floor are also rotated together with the engine bonnet, and the self-propelled aircraft in front of the engine is also opened. The
Accordingly, the engine and the self-propelled aircraft in front of the engine can be opened by moving the engine bonnet, the driver's seat, the control tower, the driver's floor, the side wall, and the operation panel all at once.

  Therefore, according to the third aspect of the invention, the engine bonnet, the control tower, the operation unit floor, the side wall, and the operation panel are moved all at once to quickly open the engine and the self-propelled aircraft in front of the engine. In addition to the above work, work such as inspection of the transmission system from the engine to the traveling device and the pre-cutting processing unit can be efficiently performed. Moreover, in order to open the front side of the engine so that it can be easily operated, the engine bonnet, the operation part floor, etc. can be moved easily while maintaining the same or almost the same height as that in the closed state. Inspection work can be advantageously performed.
