Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a harvesting machine, and more particularly to a harvester which digs a harvested product, mainly an onion, from a field and successively stores the onion in a container for harvesting.

[0002]

2. Description of the Related Art Conventionally, as this type of harvester, for example, the structure described in Japanese Utility Model Publication No. 54-22687 is known. According to the structure described in this publication, an extension conveyor is provided rotatably in the vertical direction behind the unloading end of the loading conveyor, and a drop buffer plate is rotatably provided in the vertical direction behind the extension conveyor. This is a structure in which the drop buffer plate is interlocked with the vertical movement of the extension conveyor.

[0003]

In the structure described in the above publication, when the field is flat and the loading conveyor is not tilted to one side in the width direction, the harvesting operation of the harvested product is performed, The object is conveyed toward the unloading end portion over the entire conveying surface without being biased to one side in the width direction of the conveying surface of the loading conveyor. However, if the field is sloping,
Since harvester tilts low had way direction of slope, the lower the slope as well conveying surface of the loading conveyor and the extension conveyor
To inclined direction, crops that are transported by the loading conveyor together with the conveying surface of the loading conveyor is conveyed offset to the lower portion of the lower inclined land direction, extending from the carry-out end of the loading conveyor conveying surface of the conveyor is inclined land
The load is conveyed to the lower side in the lower direction, so that the harvested products are dropped from the carry-out end of the extension conveyor to one side in the container and stored, and the harvested products must be manually leveled. There is an inconvenient problem that it requires.

Therefore, the present invention has been made in view of such a point, and even when the field is a sloping land, the conveying surface of the loading conveyor for loading the harvested product into the container is horizontal.
This loading conveyor can be adjusted and set to
Face can be reliably prevented from being inclined in the low had way direction of slope, Therefore, loading in the width direction of the entire conveying surface of the conveyor can carry crop, crop of conveying surface Since it can be prevented from being conveyed in a state of being offset in the width direction, therefore, the harvested product can be carried out and stored in an orderly manner without being biased to one side in the container, and the harvested product in the container is The purpose is to provide a harvester with excellent workability that requires less leveling .
It is those that.

[0005]

According to the invention described in claim 1, a dug body and a dug up body in the front side portion are dug up.
