のである。Thus, during the revolution and rotation of the sorting cylinder (4), the leakage of scrap rice in the mesh (61) is promoted by the centrifugal force action at the time of revolution, and the reverse of the revolution direction (a). The brown rice is agitated in a uniform distribution state in the tube (4) by the rotating and stirring action to further promote the separation of the scrap rice, and the brown rice is allowed to flow well while rotating along the inner peripheral surface of the tube (4). It improves the processing capacity.

向上させることができるものである。Further, in the mounting structure of the scraper (60), the scraper (60) is exchangeably fixed to the hexagonal shaft portion (12a) of the main shaft (12) through the bolt (58), and both end edges thereof are Since it is slidably contacting the outer peripheral sorting surface of one sorting cylinder (4) (4), a single scraper (60) can be used to scrape multiple sorting barrels (4), and the scraper (60) ) Is attached to the main shaft (12) that rotates the sorting cylinder (4) and makes the same rotation, so that the relative positional relationship can be kept unchanged and it can always be in sliding contact with the outer peripheral working surface of the sorting cylinder (4). The scraping effect can be improved, and the scraper (60) is brought into sliding contact with the main shaft (12) adjacent to the sorting cylinder (4), which has the weakest revolving centrifugal force during rotation. Since the state is such that it acts on the scraping side on the inner peripheral side, the scraping effect can be further improved.

効果を奏する。[Effect of the Invention] As is apparent from the above-described embodiments, the present invention is provided with a rotary sorting cylinder (4) vertically arranged to separate and remove scrap grains from the grain, and the sorting cylinder (4) is provided. In the structure in which the sorting cylinder is allowed to rotate while revolving, the base end of the elastic scraper (60) is integrally attached to the main shaft (12) that revolves the sorting cylinder (4), and the scraper ( Since the tip end of 60) is brought into sliding contact with the outer peripheral surface of the sorting cylinder (4), the spindle having the weakest revolving centrifugal force during rotation of the sorting cylinder (4).
A scraper (60) can be slidably contacted to the outer peripheral surface of the cylinder close to (12) so that the centrifugal centrifugal force can be applied to the inner peripheral side of the cylinder, and the scraping effect can be improved. In addition to the above, the scraper (60) is integrally provided on the main shaft (12) that revolves the sorting cylinder (4), and the relative positional relationship between the sorting cylinder (4) and the scraper (60) remains unchanged. The working surface of the scraper (60) can be slid over the entire surface of the sorting cylinder (4) at all times, and the scraping effect can be further improved, and the scraper (6) of the spindle (12) can be further improved.
By attaching the middle part of (0) and sliding the both edges to the outer peripheral surfaces of the two sorting cylinders (4), it is possible to scrape off the multiple sorting cylinders (4) with a single scraper (60). It has a remarkable effect.
