である。In the working section (2), a weeding case (18) at the center is arranged on the center line in the left-right direction, and a scraping path between the left and right scraping belts (19) and a left and right pull-out belt ( 21) to form an upper clamping conveyance path between the left and right ball portion conveyance belts (23).
The left and right scraping belts (19), the left and right pull-out belts (21), and the left and right ball section conveying belts (23) are arranged at symmetrical positions about the left and right center lines of the working section (2), and the central weeding case (18) Left and right weeding cases (18) with the same spacing as the cultivating strips of onions (16) excavated on the left and right sides of
Is arranged, and the vehicle runs across the ridge (14) so that the left and right centers of the working unit (2) pass through the center of the two onions (16) on the left side in the body traveling direction of the ridge (14). The onion (16) is excavated, and the excavation order of the onion (16) of each ridge (14) is, as shown in FIG. 7, from one end of one ridge (14) to the other. Advancing toward the end of the aircraft, excavating two strips on the left side in the traveling direction of the aircraft, turning to the right, and moving forward from one end of the ridge (14) on the right side to the other end. The body is advanced in the direction opposite to the process, and two strips on the left side in the body traveling direction are dug. All the ridges (14) are formed by the continuous digging step (A) in which the excavation work of one round trip and two steps is sequentially developed to the ridge (14) on the right side in the traveling direction.
Excavation of two strips on one side. After that, the two strips remaining in each ridge (14) are subjected to a continuous drilling step (B) similar to the continuous drilling step (A) except that only the work start position and the direction with respect to the field are reversed. Is what you do. In this excavation work, the rounding performed at both ends of the ridge (14) can be easily performed with a large radius, and the work efficiency is improved, compared with the excavation work in which two rounds of reciprocation are performed for each ridge (14). It is valid.
