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, while traveling, the dug onion is discharged into a field, and then the onion is collected one by one or several onions are bound into one collection. Post-processing is performed, but there is a problem that the directions of the released onions are not uniform and it takes time to collect and bind.

[0003]

SUMMARY OF THE INVENTION However, the present invention provides a left and right drive wheel which travels in a valley on both sides of a ridge on which root crops are planted, and a nipping transport path for holding foliage growing on the upper surface of the ridge. A pull-out transfer device formed upward, a lower transfer device provided below the pull-out transfer device and forming a lower holding transfer path for holding a neck of the crop after the pulling toward the rear, a pull-out transfer device, and a lower portion A cutting device for cutting the foliage by providing a height adjustable between each of the nipping and transporting paths of the transporting device, wherein a locking ring is provided on one side of the nipping and transporting path at the feed end of the lower transporting device. The body is provided with an aligning and transporting device on the opposite side that forms a predetermined angle with the lower transporting device and lays down the crop in one direction, so that the crop can be aligned and released in one direction, making post-harvest post-processing easier. Can be performed, and also suspended storage When cutting the foliage at the feed end side of the lower transport device where it is necessary to leave the foliage of the crop longer and the distance between the pull-out transport device and the lower transport device is widest and the cutting device can be arranged at a higher position However, since the aligning / conveying device is provided from the feed end side of the lower conveying device, the crop is held in the planting position up to the cutting device, so that the cutting length and cut length can be stabilized, and post-processing is also easy in this regard. It can be done.

[0004] Further, by bringing the feed end portion of the aligning and conveying device as close as possible to the vicinity of the axle and to the upper surface of the ridge,
Since the aligning and transporting action of the aligning and transporting device works up to the upper surface of the ridge, the release attitude and position can be stabilized as compared with the drop type, and in this regard, post-processing can be performed more easily, and at the same time, the crop is prevented from being damaged. In addition, since the feed end of the aligning / conveying device is near the axle, the feeding end of the aligning / transporting device, such as during circulating, can reliably follow irregularities on the ground and move up and down, thereby preventing interference damage to the ground. It is.
