Description

  The present invention relates to a rotary sorting device that sorts grains by a rotating drum, and a sorting device that includes a removal device that separates fine stone particles during conveyance by a conveyor arranged below the rotary drum.

  Conventionally, an object to be sorted is supplied to one end of an outer cylinder into which the conveyor is inserted, and a small hole is passed through the lower surface of the outer cylinder, followed by a large-diameter hole, and the conveyor rotates. There is a rotary sorter that sorts large and small foreign objects, which is a desired purpose, while transferring an object to be sorted to the end side (see, for example, Patent Document 1). This configuration is a sorting device that rotates a conveyor device within a single cylinder to separate small foreign matters and large coarse items, and does not have a structure in which large and small foreign matters are individually sorted by upper and lower sorting bodies. In addition, a rotation sorter that sorts grains while forming a number of holes on the outer peripheral surface and rotating is installed, and a rotation is provided with a conveyor that conveys and discharges the separated small grains and other debris to a predetermined position. There is a type sorting device (see, for example, Patent Document 2). In the prior art provided with wheels, a roller is disposed at the bottom of one side of the hulling machine, a lever that rotates from a substantially vertical position to a horizontal state is provided, and a connecting rod connected to the link arm of the roller is connected to the engaging portion of the lever. There is a lifting device that connects and lifts the huller (see, for example, Patent Document 3). However, the former conveyer conveys the grain after sorting without providing a sorting function, and the latter is a lifting device that makes it easy to move heavy objects by protruding a single row of rollers. .
