DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frame structure of a traveling machine in a paddy field working machine in which a front side of the traveling machine is covered with a bonnet.

[0002]

2. Description of the Related Art In general, a paddy field working machine such as a walking type rice transplanter having a planting portion on the rear side of a traveling body and an engine section on a front side of the traveling body has a front side of the traveling body. A bonnet is provided above to cover various parts on the fuselage,
2. Description of the Related Art There has been known an apparatus in which the appearance of a traveling body is adjusted.

[0003]

In the conventional paddy field working machine, there is only a body frame for supporting a seedling planting section, an engine section, and the like on the lower side of the traveling machine body. Since there was no member to support the hood, parts such as the bonnet and the fuel tank separately mounted on the upper part of the traveling aircraft tended to be misaligned with respect to each other, and therefore, in terms of assemblability and appearance quality. There were various problems. In addition, the support members that support various parts such as the bonnet and the fuel tank are composed of covers such as side covers, and these covers finely divide the space above the fuselage frame in side and plan views. Therefore, it is not easy to arrange and arrange other attachment parts and the like to be attached to the body frame.

The present invention has been made in order to solve the above-mentioned problems, and is intended to easily place components such as a bonnet and a fuel tank disposed on an upper portion of a traveling body in a related position with a small error. On a paddy working machine that can be mounted on a paddy working machine, which can improve assemblability and appearance quality, and further increase the rear space of the traveling machine body and can be used effectively for mounting other attachment parts. It is intended to provide an airframe structure.

[0005]

In order to solve the above-mentioned problems, a technical measure taken by the present invention is to provide a seedling planting portion on the rear side of the traveling body and a front section of the traveling body provided with the engine section. In a paddy field working machine whose side is covered with a bonnet, a lower frame in the front-rear direction for supporting an engine section, a seedling planting section, and the like is provided on a lower side of the traveling body, and a bonnet mounting section is provided above the lower frame. The upper frame is provided in the front-rear direction, and the front end of the upper frame is erected on the front of the traveling aircraft
Fix to the connecting member, and stick the rear end of the upper frame
Material to the lower frame and inside the upper frame
Part of the engine mounted on the front side of the lower frame.
It is characterized in that it is connected and fixed to the upper part, and in a paddy working machine in which a seedling planting part is provided on the rear side of the traveling body and the front side of the traveling body provided with the engine part is covered with a bonnet,
A lower frame in the front-rear direction supporting an engine part, a seedling planting part, and the like is provided on a lower side of the traveling body, and an upper part in the front-rear direction formed substantially along the periphery of the bonnet above the lower frame. A frame is provided substantially parallel to the lower frame, and the front end of the upper frame stands on the front of the vehicle.
The rear end of the upper frame is connected to the lower frame by a rod-shaped support member provided at a position where the rear end of the upper frame wraps with the planter arm of the seedling planting part in a side view.
The middle part of the lower frame to the front of the lower frame.
And is fixedly connected to the upper part of the engine .

[0006]

Therefore, according to the present invention, parts such as a bonnet and a fuel tank disposed on the upper part of the traveling body are
By simply attaching the vehicle to the upper frame, the positions of the vehicle body and the vehicle body are reduced, so that the assemblability and appearance quality of the traveling body are improved. The upper frame, which is formed almost along the rim of the bonnet, securely supports the bonnet covering the components in an appropriate position, so that attachment parts such as auxiliary seedlings and the like arranged on the bonnet can be attached. Becomes easier. Since the upper frame and the lower frame provided in the front-rear direction are connected by a rod-shaped support member that wraps with the planter arm in a side view, a wide space that is not divided by covers or the like is formed at the rear of the traveling body. Also, attachment of other attachment parts becomes easy.
