DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a harvester for digging root crops such as onions and carrots from a field.

[0002]

Conventionally, a raising member for erecting the foliage of a crop, a raking member for raking the raised foliage, and pulling and transporting the crop by nipping the foliated foliage are provided. However, since the ground height of the starting point of the raking member was higher than the starting point of the raising member, the raking force was applied to the upper side of the foliage of the crop, and the foliage was increased. Only the upper part is inclined in the scraping direction and tilted left and right, so that the scraping force cannot be used as a digging assisting force to swing the crop left and right, and it is not easy to reduce the crop pulling force by the transport member And so on.

[0003]

SUMMARY OF THE INVENTION The present invention provides a raising member for erecting a foliage of a crop, a raking member for raking the raised foliage, and clamping the foliage which has been raked. In a harvester provided with a transport member that pulls out and transports the crop,
The raking start side of the raking member is arranged as close as possible to the field scene, and is applied to the ridge surface by applying the raking force of the raking member to the above-ground portion of the crop. The foliage can be easily pulled up, the scraping force can be used as a digging assistance force to shake the crop left and right, the pulling force of the crop by the transport member can be reduced, and the foliage is cut and separated at the time of pulling out, so that the crop can be separated. It can be easily prevented from remaining in the field.

[0004] Further, the raising start end of the raising member and the squeezing start end of the raking member are disposed at substantially the same ground level.
The height of each member relative to the ground can be easily adjusted.
