Since the belt outer peripheral surfaces on the left and right inner sides of the transport belts 17 and 17 are provided in contact with or close to each other, the extracting and transporting device 2
The right and left transport belts 17, 17 accurately transport the crop body P upward while sandwiching the stem a on the root side of the crop body P, and reliably remove the crop body P from the field G. In addition, the transfer body of the upper transfer device 15 is constituted by transfer belts 16, 16 arranged side by side on the upper side of the extraction transfer device 2.
Since the outer peripheral surfaces of the belts on the left and right inner sides of the conveyor belt 16 are separated from each other at intervals wider than the intervals on the left and right inner sides of the conveyor belts 17 and 17 of the extraction conveyor 2, The crop P is transported upward with respect to a portion above the stem a on the root side of the crop body P, that is, a portion where a large amount of the final crop B is attached, but damage to the final crop B hardly occurs.

Since the left and right transport belts 16 of the upper transport unit 15 are provided with a plurality of lugs 16a.
The plurality of lugs 16a..., 16a.
The crop body P can be transported accurately regardless of the width of the crop body P by getting into and catching in the thick branches and leaves.

Therefore, the harvesting machine 1 can perform the harvesting operation of extracting the crop body P such as green soybeans from the field G by a machine that has conventionally been performed manually, thereby saving labor. In addition, the sampling and conveying device 2 conveys the crop P upward with the stem a on the root side of the crop P interposed therebetween.
Is extracted from the field G, so that the final crop B is less likely to be damaged. Also, a stem a on the root side of the crop body P
Is transported while being sandwiched by the extraction transport device 2, and the upper portion thereof is transported while being sandwiched by the upper transport device 15. Therefore, the crop P can be extracted in a proper posture and transported upward. When the crop P falls in the left-right direction or the front-rear direction during the extraction transport, the final crop B is extracted and transferred. A situation in which the body is caught and damaged by another body member is less likely to occur.

Then, the carrier 16 of the upper carrier 15
The transport start end S1 of the transporter 1 of the extraction transport device 2
Since the crop body P is located at the same position as the transport start end portion S2 of 7, 7 or behind it in the work traveling direction, the crop body P is pulled up by the upper transport device 15 before the extractive transport device 2 receives the extracting operation. It is possible to avoid occurrence of a situation in which the final crop B is scraped off.

Further, since the belt outer peripheral surfaces on the left and right inner sides of the left and right conveyor belts 17 of the extraction conveyor 2 are provided in contact with or close to each other, the crop P can be reliably extracted from the field G. In addition, since the outer peripheral surfaces of the left and right inner belts of the left and right conveyor belts 16 of the upper conveyor 15 are spaced apart from each other at a wide interval, the upper conveyor belt 15 is conveyed upward with a large portion of the final crop B therebetween. Also final crop B
Damage is unlikely to occur.

Further, lugs 1 protruding outside the belt rotation area are provided on the left and right conveyor belts 16 of the upper conveyor 15.
, 16a, etc., the crop P can be transported accurately regardless of the width of the crop P.
