And a pair of cutting mechanisms are mounted on the traveling machine body, and the pair of left and right foliage raising mechanisms has a front vertical raising mechanism and a subsequent scratching mechanism, respectively, and a left and right vertical raising mechanism and a scraping mechanism. The insertion mechanism is that at least one of the right and left sides can be adjusted in the left-right direction corresponding to the interval between the two central crops of the four crops.

In addition, another technical means of the present invention is that each of the left and right foliage raising mechanisms is circulated and moved backward and upward so that the foliage of the two crops is swept toward the center. A pair of left and right scraping means each having a scraping claw is provided, and the left and right scraping mechanisms have a left and right position corresponding to two crops of each of the four crops. The scraping means on the left and right inner sides and the scraping means on the left and right inner sides of the other scraping mechanism are arranged so as to overlap vertically.
Further, another technical means of the present invention is that, among the four scraping means of the left and right scraping mechanisms, the scraping claws of the scraping means on both the left and right outer sides are scratched by the other scraping means on the left and right inner sides. It is in the point formed long compared with a nail.

According to another technical means of the present invention, each of the left and right scraping mechanisms is supported on an upper pulling mechanism and power is transmitted via a transmission shaft. The angle can be changed around the transmission shaft with respect to the upper pulling mechanism so as to change the left-right position of the front end.
According to another technical means of the present invention, the upper and lower pull-out mechanisms are each composed of a pair of left and right belt conveyor means, and the front side and the front side of the left and right belt conveyor means are angled with respect to the rear side.
