Abstract

PURPOSE:To compact a crop sorting device by extremely shortening the carrier route of an endless turning band while setting the width of a sorting recovering part to the maximum width wherein working efficiency is considered in the automatically sorting device for crop. CONSTITUTION:A crop sorting device is constituted so that, while crop fed in a columnar shape by an endless turnable type carrier conveyor A is placed and carried, this crop is allowed to selectively fall and recovered in a plurality of recovery parts 4 described below via the guide chutes 18 formed of rectilinear routes on the basis of the measured result. The recovery parts 4 are parallel equipped along the carrier route of the carrier conveyor A in the lateral side thereof. The width of the other guide chutes 18 exclusive of the following guide chutes 18 is set at the nearly same width as the width of the recovery parts 4. The said guide chutes 18 are positioned respectively in the uppermost part side in the carrier direction of the carrier conveyor A and in the lowermost part side in the carrier direction thereof. The width of these guide chutes 18, 18 in both end part sides is set at the width narrower than the width.

供する点にある。However, in the above-mentioned conventional structure, the widths of the plurality of conveyors for collecting the objects to be sorted are all set to the maximum required width in consideration of work efficiency, and the widths of the plurality of guide chutes are set. If all the widths are set to be the same as the width of the conveyor, there is a drawback that the operation length of the endless rotation belt for conveyance becomes long and the apparatus becomes large. An object of the present invention is to make the carrying action length of the carrying endless rotation belt as short as possible by a rational improvement, thereby making it possible to make the device compact and surely perform the guiding action for sorting and collecting. The point is to provide things.

がない。In the progressive feeding device 3, the transported crop C is transferred to the transporting body 21 on the lower side in the transporting direction by the upward movement of the transporting body 21 by the crop placing surface 21a in the inclined posture. The transfer target crop C is transported by sequentially repeating such transfer movements. At this time, since the conveyed crop C before being transferred to the conveying body 21 moving downward is received and supported by the front surface of the next conveying body 21, the separation is reliably performed. In addition, since the width of the carrier 21 along the carrying direction is substantially equal to the width of the transported crop C, and the carrying width in the direction orthogonal to the carrying direction is gradually narrowed, such a transfer movement Is repeated a plurality of times, the transported crops C, which are overlapped by two or more, are leveled one by one, and are securely placed one by one near the end portion. Then, the crop C to be transported is 1 on the narrow carrier 21.
Even if it is sent in an unstable posture as if only part was placed,
Since the width of the transport body 21 at the end position is large, the carrier 21 always has a stable posture at the transfer position to the weighing and sorting apparatus 5,
At the time of transfer to the weighing and sorting apparatus 5, when the transfer body 21A at the final end of the transfer moves downward, the transfer body 21A moves onto the tray 13 at once without rolling, and the mounting posture does not become oblique.
