Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a grain pedestal mounting structure in a combine in which a grain pedestal that supports a grain bag is stored below the outer side of a grain tank and is expandable. Regarding

[Conventional technology]

Conventionally, in a combine that is configured by detachably connecting a hopper having a discharge port in the lower part to the lower part of the outer surface of the grain tank, the grain pedestal below the hopper has a structure that can be folded and stored on the machine side. Was becoming.

[Problems to be solved by the device]

In such a structure, since the hopper is provided at the lower part of the outer side surface of the tank, the hopper position is inevitably lowered, so when the grain pedestal is stored on the machine side with the hopper connected, it hits the hopper. The grain pedestal must be mounted low so that it does not interfere with the hopper. When the grain pedestal is stored in such a lowered state, it is easy to hit an obstacle on the ground, which causes a problem.

[Means for solving problems]

The present invention solves such a problem and makes it possible to store the grain pedestal upward and satisfactorily with or without the hopper attached to the outer surface of the tank. Therefore, the upper and lower ends of the bending supporting rods, which are constructed by connecting two supporting rods with fulcrum shafts and are bendable, are pivotally attached to the left and right brackets on the outer side of the fuselage which are the lower direction of the hopper. On the lower end of the supporting rod, the side end of the grain pedestal is rotatably pivoted, and the bending supporting rod hangs down without refraction, and the hopper and the bending supporting rod bend upright. Is installed and configured so as to be positionally fixed at a position where it wraps up and down in a side view.

[Action]

Therefore, when the hoppers are continuously installed, bend the bending support to stand up and pull it up to a position where it overlaps with the hopper vertically in side view. It can be stored high and compactly. With the hopper removed, if the grain pedestal is further erected and fixed in position from the above state, it can be raised further and stored closer to the fuselage side.
