[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a structure of a succession unit that inherits a harvested product from a vertical conveyance belt to a horizontal conveyance belt of a harvester such as a root vegetable harvester that excavates and harvests root vegetables such as radish in a field.
[0002]
[Prior art]
Conventionally, a control unit is provided on the right side of the traveling machine base, and a vibration blade that lifts the root portion on the left side, and a pulling conveyance belt that holds the foliage portion of what is lifted by the vibration blade and pulls it up obliquely upward, The pulling and conveying belt is obliquely installed in a slanted state at the front low and high to the rear of the machine body, and it is configured so that the oblique installation angle can be changed by turning around a turning fulcrum shaft provided in the middle part in the front-rear direction. 2. Description of the Related Art A root crop harvesting machine is known in which a start end portion is positioned below a terminal end portion of the pulling and transporting band to inherit a transported product and a horizontal transporting belt that is transported to the rear side of the control unit is provided horizontally.
[0003]
In the root vegetable harvesting machine, the vertical position of the rotation fulcrum shaft is fixed, and when the extraction conveyance band is rotated around the rotation fulcrum axis, a pretreatment device mounted on the front end of the extraction conveyance band Is configured to move up and down, so in order to adjust the size of the gap between the terminal end of the pull-out transport band and the start end of the horizontal transport band, there is not much rotation of the pull-out transport band, There was almost no change in the gap between the terminal end of the drawing conveyance band and the start end of the horizontal conveyance band due to the rotation of the drawing conveyance band. In addition, since the position of the horizontal transport band is fixed and cannot be moved in the front-rear direction, the front-rear position between the start end of the horizontal transport band and the end of the pull-out transport band cannot be adjusted. .
[0004]
[Problems to be solved by the invention]
The size, length, shape, and the like of the root vegetables harvested by such a root vegetable harvesting machine are different from one another, and in particular, there may be variations between harvesting times and fields. The root vegetables lifted by the vibrating blade at the front of the machine is pulled up by the pulling conveyance belt on the side of the machine and conveyed to the rear of the machine, and falls downward from the terminal end of the drawing conveyance band to the top of the horizontal conveyance band. However, if the harvested root vegetables are different in size, length, shape, etc., when they are inherited to the start end of the lateral transport belt, the inheritance posture is different.
