The inclination angle (α) of the ball discharge belt (27) in the left-right direction is determined by the line (L) between the left and right pull-out belts (22) and between the left and right ball transfer belts (24). The angle is set so that the ball portion (16b) is biased toward the upper surface of the left ridge (14) to be released, and the ball portion (16b) is constantly aligned and released toward the left side of the upper surface of the ridge (14) with respect to the traveling direction. By doing so, as shown in FIGS. 1 and 2,
For example, one row (14) has four rows of onions (16), and one row (14) makes one reciprocation (two half steps) to produce four rows of onions (16). In the case of harvesting, the two ball portions (16b) harvested in the first half-process are released by being biased toward the left side of the upper surface of the ridge (14), that is, one side of the upper surface of the ridge (14) with respect to the traveling direction. Go, the two rows of balls (16b) harvested in the latter half of the process (16)
Ridge on the left side of the upper surface of the
4) One side of the upper surface is released and released. In this way, the center part of the ridge (14) is emptied, and the two-piece ball (16b) is harvested in the first half-process, so that the ball (16b) for the latter half-process does not disturb the walking of the worker. Then, it is possible to concentrate on the traveling work operation, and the harvested ball portion (16b) is placed on the unharvested foliage portion (16a), and the harvested ball portion (16
It is configured to prevent b) from interfering with the subsequent harvesting operation or disturbing the alignment of the ball portion (16b) harvested during the subsequent harvesting operation. The lower end of the ball release belt (27) does not drop and release the ball (16b) from above the ridge (14), but instead places the ridge (14) on the upper surface of the ridge (14). It is provided as close as possible to the upper surface.
