Description

  The present invention relates to a sorting apparatus that sorts agricultural products such as potatoes according to the shape thereof, and can quickly adjust the size of an object to be sorted.

  Conventionally, when trying to sort agricultural products strictly by size, the weight has been measured and sorted, but if you want to sort efficiently, but not so strictly, its shape Shape sorting is performed by measuring and sorting.

  The case where you want to sort efficiently is when you want to sort the shape of the harvested agricultural products in order to remove stone rubble, clumps, and small balls that do not become commodities. In addition, in order to carve potatoes as seed varieties, for example, when selecting shapes for two or three cuts.

  As the shape sorting device, a plurality of shafts are arranged in parallel, and a plurality of discs are inserted at intervals of a desired size for each of the shafts, and the discs are rotated in the same direction. It has been known.

  For example, in Japanese Utility Model Publication No. 49-23445, a part of a roller made of an elastic body is cut into a shape of a target object by combining two rollers, and the roller is fitted to a rotating shaft to be the same. A technique is shown in which rollers are stacked up and down so that the holes formed in the direction of rotation are smaller in the downward direction.

  However, when it is desired to sort efficiently as described above, the size is not standardized as in the case of shipping as a product, but the distribution of the overall size at the time of harvest, which will vary from year to year. Depending on the situation, the size to be selected changes. In other words, if the distribution of the overall size is large at the time of harvest, you want to increase the size of the small balls, and in the opposite case, you want to increase the yield by a small amount. The Also, in the case of seed potatoes, if the distribution of the overall size is large, the size that was previously used for tri-cutting may also be used for double-cutting, and fine adjustment of the size to be selected is required. The

  However, the technique disclosed in Japanese Utility Model Laid-Open No. 49-23445 is obtained by cutting a roller into the shape of an object, and fine adjustment of the size to be selected is impossible. Therefore, a plurality of shafts are arranged in parallel, and a plurality of discs are inserted at intervals of a desired size for each of the shafts, and a plurality of ring spacers are inserted between the discs. There are known ones in which the size to be selected by increase / decrease is finely adjusted.

  However, this also requires a large number of disks and ring spacers to be taken in and out of the shaft, and fine adjustment of sorting is complicated. Therefore, there is also known one that can quickly adjust the distance between the disks.

  For example, in Japanese Patent Laid-Open No. 9-225410, a plurality of rotating shafts arranged in front and rear in a left and right frame are supported, and a plurality of discs are externally fitted on each rotating shaft so as to be arranged in a straight line, and adjacent front and rear. It is shown that this is an agricultural product sorting device that sorts agricultural products by a rectangular gap between the rotation axis of the slab and the front, rear, left and right discs.

  Further, in order to fix the disc to the rotating shaft and to be slidable, each rotating shaft is made up of both shaft end portions that are supported by the left and right frames, and a shaft portion having a U-shaped cross section that integrally connects the shaft end portions. Forming a prismatic driving cam and driven cam on the shaft, forming a bolt on one end of the driving cam and projecting outward from the shaft end, and fitting a nut on the bolt; When the nut is rotated to slide the driving cam in the axial direction, thereby causing the driven cam engaged with the driving cam to enter and exit from the opening of the shaft portion, and to advance the driven cam from the shaft portion A technique is shown in which the disc loosely fitted to the shaft portion is fixed to the rotating shaft, and when the driven cam is retracted into the shaft portion, the disc can slide on the shaft portion. Yes.

Further, in order to make the interval between the plurality of discs constant, guide rods are passed to the left and right frames below the respective rotation shafts in parallel to the respective rotation shafts, and are guided so as to sandwich the respective discs with the guide rods. A technique is shown in which a scraper is attached so as to be movable left and right, and all the scrapers on one guide rod are connected via a pantograph mechanism.
Japanese Utility Model Publication No. 49-23445 JP 9-225410 A

  In the technique disclosed in Japanese Patent Application Laid-Open No. 9-225410, in order to fix the disc to the rotating shaft and make it slidable, a prismatic driving cam and driven cam are internally provided on the shaft portion corresponding to each disc. However, in order to make the interval between the plurality of discs constant, a scraper and a pantograph mechanism that can move left and right are used, and the structure is quite complicated.

  Also, the adjustment operation is the same as rotating one nut of the driving cam to slide the driving cam in the axial direction so that the disk can slide on the rotating shaft. The distance between the disks on the shaft is the same, and the nut is rotated again to slide the driving cam in the axial direction to fix the disk to the rotating shaft. It is difficult to say that it is convenient.

  This is a complexity for making the intervals of the disks on the same axis variable, and it is necessary to be able to make adjustments according to the size of the object to be sorted while keeping the intervals on the same axis fixed. .

Although an example in which the selection spaces S1 and S2 of the same size are passed twice has been shown, the number of fixed rotation shafts and movable rotation shafts may be increased so as to pass through more selection spaces, or fixed rotation. It is also possible to use one shaft and one movable rotating shaft and pass through the sorting space once.

  Moreover, although the screw shafts 42 and 52 of the slide drive units 40 and 50 are rotated and the movable rotary shafts 12 and 22 are slid, the movable rotary shafts 12 and 22 are linked by a link mechanism, a crank mechanism, a hydraulic cylinder, or the like. 22 may be slid.

  Moreover, although the crank-shaped thing was shown as the handles 65 and 66, a round shape and another shape may be sufficient.
