Are provided on the same plane, and one horizontal connecting rod (177) penetrates through the left and right side pieces (175a) of each scraper (175) so that the cutout grooves (176) of each scraper (175) are oriented in the same direction. Above, the scrapers (175) are integrally connected in a state of being arranged in a horizontal line at equal intervals, and the small ball removing rollers (15) are integrally connected.
4) One scraper (175) county is constituted. Of the plurality of bead removal rollers (154), the bead removal rollers (154) other than the rearmost bead removal roller (154) are provided with horizontal connecting rods (17) of a group of scrapers (175) below.
7) is horizontally laid on the left and right sorting frames (149) with the main piece (175b) of each scraper (175) standing, and each large-diameter roller portion (154b) of the small ball removal roller (154) is scraped by the scraper (175). The large-diameter roller portion (154b) is rotated by being fitted into the notch groove (176) of the main piece (175b) of each scraper (175) in the county to rotate the notch groove (17).
6), the mud and debris adhering to the end face and the left and right side surfaces of the large-diameter roller portion (154b) are removed from the main piece (17).
At the same time as scraping in 5b), the tip of the main piece (175b) scrapes off mud and debris adhering to the peripheral surface of the small-diameter roller portion (154a), and adheres and accumulates and debris mud on the small ball removal roller (154). By removing and wrapping the leaves, the small ball removal roller (15
The gap between the small-diameter roller portions (154a) in 4) is reduced or closed to prevent the performance of separating small beads and small stones from being reduced. Roller for multiple small beads (15
Of the 4), the rearmost sorting roller (154) has a scraper (175) and a horizontal connecting rod (177) of each group between the scraper (175) and the front revolving section of the sorting conveyor (151). ) Is laid on the left and right sorting frames (149) with the main piece (175b) lying down, and each large-diameter roller portion (154b) of the small ball removal roller (154) is scraped by each scraper (175). Main piece (175
The scraper (175) of the small bead removing roller (154) other than the last part is inserted into the cutout groove (176) of b).
The same operation and effects as those of the county are obtained, and between the rearmost small ball removal roller (154) and the front revolving section of the rear separation conveyor (151) (the small ball removal conveyor (150) and the separation conveyor (151)). Between the scraper (1)
75) By filling the counties and further bridging with the main piece (175b) of each scraper (175), the onion is stagnated at the inheriting portion of the front small-diameter conveyor (150) from the rear-side sorting conveyor (151). Inherited and conveyed smoothly without clogging. In addition, by using the scraper (175) group as a succession guide between the small ball removal conveyor (150) and the sorting conveyor (151), a dedicated succession guide is unnecessary, which contributes to cost reduction. A rubber plate (175c) is attached to the main piece (175b) of each scraper (175) in the last scraper (175) group to prevent the onion from being damaged.
