When it is fully loaded, it is moved laterally outward from the horizontally-moving pedestal 35 and dropped on the field to be placed.

In the harvesting machine constructed as described above, the traveling device 1 is caused to travel in the traveling direction d of the machine body, and during the traveling, the extracting / conveying device 2 sandwiches the root part r of the crop body P. The crop body P is conveyed upward and taken out from the field E.
Further, the soil separating device 4 divides the left and right soils of the root part r of the crop body P into left and right, and the soil discharging device 3 separates the left and right outer soils of the soils divided into the left and right outwards. It is moved and discharged, and the crop body holding start end S of the sampling and conveying device 2 advances to the places where the left and right soils have been discharged in this way, and the root part r of the crop body P that was in the ground is extracted. The transport device 2 sandwiches and transports the crop body P upward, and extracts the crop body P from the field E.

Therefore, the harvesting work of withdrawing the crop body P such as edamame from the field E can be performed mechanically and continuously, and labor saving can be achieved as compared with the conventional manual work. Moreover, the root part r of the crop body P in the ground is excavated by the soil discharging device 3.
Since the soil on the left and right of the plant is discharged, and the soil is extracted and sandwiched by the transport device 2 and transported upward, the crop body P is extracted from the field E,
The final harvested product B near the ground of the crop body P is less likely to be caught and damaged by the transport device 2. Further, since the left and right soil of the root part r of the crop body P is divided into left and right in advance by the soil separating device 4, the soil is satisfactorily discharged because the soil discharging device 3 moves the soil left and right to the outside. Can proceed well. In addition, the earth-dividing device 4 is composed of a flat plate, and the earth-dividing plates 4a, 4a whose plate surfaces are in a posture along the machine body advancing direction d and the up-and-down direction are provided on the left and right sides of the earth-discharging action portions 3a, 3a of the earth-discharging device 3. Since it is arranged on the left and right in front of the inner end portion, the soil dividing plates 4a, 4a, which are running, are divided by the straightness of the soil dividing plates 4a, 4a.
4a is less likely to be displaced left and right, and therefore the root portion r of the crop body P is less likely to come off between the left and right soil dividing plates 4a, 4a. It is possible to properly continue the soil discharging and the nipping and conveyance of the root portion r of the crop body P, and the work of extracting the crop body P can be favorably carried out.
