Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] According to the present invention, a track frame is provided for each of a pair of left and right crawler traveling devices, and a plurality of connecting frames for connecting a plurality of front and rear directions of the track frames are provided. A pair of left and right main frames, which are formed in a mountain shape with the longitudinal middle portion positioned above, are mounted on the longitudinal middle portions of the plurality of connecting frames, and extend laterally along the vehicle transverse direction. The present invention relates to a combine frame structure in which a plurality of frames are provided in an upper side of the left and right main frames in a state of being aligned in a vehicle front-rear direction, and a driving boarding portion is provided in a front portion of the body frame.

[Conventional technology]

The frame structure of such a combine has a threshing device and a grain storage section mounted on the rear side of the vehicle body, a driving board section and a driving section mounted on the front side of the vehicle body, and a reaping processing section that is vertically movable on the front side of the vehicle body. In order to attach various devices, various connecting brackets and the like are attached.

[Problems to be solved by the invention]

Among the plurality of horizontal frames, the one on the rear side used for mounting the threshing device or the grain storage part is mounted with the threshing device or the grain storage part low, so that the car body weight can be lowered. Therefore, it is desirable to place it in a low position. On the other hand, of the plurality of horizontal frames, the one on the front side, on which the operation mounting part and the driving part are mounted, and which supports the mounting base for mounting the mowing processing part so as to be able to move up and down, is the crawler traveling device. It is desirable that the upper and lower positions are sufficiently spaced apart from each other to prevent the mud or the like attached to the crawler traveling device from adhering.

By the way, it is necessary to separate the vertical distance from the crawler traveling device only for the front side of the plurality of horizontal frames because the sprocket that drives the traveling crawler is located at a high position on the front side of the traveling crawler device. Therefore, the upper path part of the traveling crawler is
This is because the front end side is arranged so as to be inclined upward.

As shown in FIG. 6, the front end side portion of the main frame (8) is higher than the rear side portion as means for making the front side and the rear side of the plurality of horizontal frames different in height. Therefore, it is conceivable to bend and form the main frame (8), but in this case, there is a disadvantage that the entire structure is expensive due to the complicated production of the main frame (8),
It was difficult to put to practical use.

By the way, in the combine, the controller provided in the driving boarding section and, for example, the rotation speed detection sensor of the second product conveying device of the threshing device are connected by wiring to warn the second product clogging, etc. Various alarms and various controls are performed while wiring and connecting various sensors with each other. Further, in order to simplify the wiring, it is desired to simplify the holder of electric wires.

The present invention has been made in view of the above circumstances, and is to satisfy both of the above requirements at once by a simple modification.

[Means for solving problems]

The characteristic structure of the frame structure of the combine according to the present invention is
Cylindrical auxiliary frames for inserting electric wires from the driving section at the front part of the vehicle body to the devices at the rear part of the vehicle body are attached along the longitudinal direction of the main frame on the upper sides of the front ends of the respective main frames. The front side of the horizontal frames of is located on the auxiliary frame,
Its action and effect are as follows.

[Action]

That is, the auxiliary frame is attached to the upper side of the front end of each main frame so that the one on the front side of the plurality of horizontal frames is positioned at a high position. However, the front side of the plurality of horizontal frames can be made high and the rear side can be made low.

Further, the auxiliary frame has a cylindrical shape so that the inside thereof can be wired through electric wires.

[Effect of device]

Therefore, while the linear main frame can be used to simplify the overall structure, the front side of the plurality of horizontal frames is positioned high and the rear side is positioned low. It is also possible to simplify the wiring while effectively utilizing the cylindrical auxiliary frame for the wiring holder, and thus to obtain a combine frame structure that satisfies both the requirements at the beginning. I arrived.
