Description

[Detailed Description of the Invention] The present invention relates to an engine room top cover opening/closing device that allows the entire top surface of the engine room to be opened in a combine harvester in which the engine room is disposed below the driver's seat.

Traditionally, in this type of combine harvester, the driver's seat was installed above the engine room, but in order to improve the maintainability of the engine, small combine harvesters had a structure that allowed the entire engine room cover, including the driver's seat, to be opened to the side. Things existed, but
Large combine harvesters have a complex structure around the driver's seat and are large in size, so due to strength issues,
It was not possible to adopt an open structure like the above-mentioned small combine harvester. Therefore, in large combine harvesters, only the driver's seat is tilted forward, and an opening/closing lid is installed that allows you to partially push your hand into the upper surface of the engine compartment below the driver's seat. When a vertical engine is installed, engine oil is supplied through the opening of the opening/closing lid. However, when performing maintenance such as adjusting the engine tappet, adjusting the fan belt, or inspecting and replacing the nozzle especially if the engine is a diesel engine, the opening provided by the above-mentioned opening/closing lid is too narrow to perform maintenance, so the top of the engine room It is necessary to remove the entire top of the engine room, including the driver's seat, in order to open the entire surface, and if you place the removed heavy parts on an unstable aircraft nearby, it may damage the painted surface of the aircraft. Since there is a risk of the removed parts falling from the airframe, the removed heavy parts have to be carried by hand to a predetermined location on the ground. In addition, when the driver's seat is folded forward as described above, the folded driver's seat blocks the step platform, making it impossible for maintenance personnel to work on the step platform. Moreover, with large combine harvesters, the parts to be worked on are high and cannot be reached from the ground, so maintenance workers often have to ride on top of the threshing machine or hopper to perform maintenance, and doing so may damage the painted surface of the machine. This has the disadvantage that it not only causes injury, but also requires work to be carried out in dangerous conditions.

Therefore, the present invention provides an engine room top cover integrated with the lower part of the driver's seat of the combine, and the engine room top cover rotates rearward using the upper part of the paddy processing section located behind the driver's seat as a pivot point. It is an object of the present invention to provide an engine room top surface cover opening/closing device which is constructed so that the top surface of the engine room can be opened completely by moving the engine room top surface, thereby eliminating the above-mentioned drawbacks.
