As shown in FIG. 11, this type of combine harvester includes one in which an extension deck 013 is connected to the front edge of the auxiliary deck 09 and located on the lateral outer side of the driving section 07. 107757).

[Problem that the invention attempts to solve]

In the case of such a conventional combine harvester, when moving from the getting on/off step 06 to the auxiliary deck 09 or from the auxiliary deck 09 to the getting on/off step 06,
Although it is possible to quickly transfer to the farm via the extension deck 013 next to the driving unit 07 without having to go down to the field, there are still the following drawbacks.

That is, the extension deck 01 located beside the driving part 07
3 is connected to the auxiliary deck 09, the swing axis x for switching the auxiliary deck 09 between the use position and the storage position must be displaced laterally outwardly from the driving portion 07. As a result, even if the auxiliary deck 09 and the extension deck 013 are switched to the retracted position, both decks 09 and 013 remain in the driving unit 0.
It had a defect that it protruded more laterally and outwardly than 7.

In view of the above-mentioned circumstances, the present invention has been developed to provide an extension deck for quickly and easily transferring between the boarding and disembarking steps and the auxiliary deck, while also making the auxiliary deck and extension deck compact and free from rattling. It has a purpose in that it can be stored in a state.

The characteristic structure of the combine harvester according to the present invention is that an extension deck located on the lateral outer side of the driving section is placed on the front edge of the auxiliary deck so that it can be folded up and swung, and is located under the protruding part of the driving section. At the same time, a receiving member capable of mounting and supporting the free end side of the extension deck is attached to the body frame, and the extension deck and the extension An engaging portion is formed between the deck and the deck to prevent relative rotation by engaging with the deck as they move close to each other.

The functions and effects of the above characteristic configuration are as follows.

[Effect]

When moving from the boarding/disembarking step to the auxiliary deck or from the auxiliary deck to the boarding/disembarking step, the extension deck attached to the front edge of the auxiliary deck can be moved to a position outside the side of the prime mover. You can transfer to the farm without having to go all the way to the field. Moreover, at this time, after the extension deck is pushed into the fuselage frame side through the underside of the protruding part of the driving part, the free end side is placed and supported on the receiving member of the fuselage frame, so the extension deck is supported firmly. However, the receiving member can be made smaller.

In addition, when storing, the extension deck is folded onto the auxiliary deck, and then the extension deck is further folded toward the fuselage, so the swinging fulcrum for changing the attitude of the auxiliary deck can be placed as close to the fuselage frame as possible. can be placed close to. In addition, in this retracted state, the extension deck slides down in the direction of the swing axis, and the engaging portion provided between the extension deck and the auxiliary deck engages, so that the extension deck slides downward in the direction of the swing axis. Unexpected wobbling around the core can be reliably prevented.

[Effect of idea]

Therefore, even though an extension deck is provided for quickly and easily transferring between the boarding and disembarking steps and the auxiliary deck, it is possible to store the extension deck and the auxiliary deck compactly and without wobbling. can. In addition, the extension deck can be easily prevented from wobbling during storage by using the structure of the extension deck, that is, the sliding structure of the extension deck, which is necessary for downsizing the receiving member. It came to this.
