JP 11-266670 A ([0019] column, FIGS. 6 and 7)

  In the above threshing machine, since the whole of the harvested cereal culm from the stock source to the tip is supplied to the handling room and threshing is processed, the amount of straw scraps generated in the handling room increases, and the shaking sorting from the handling room The amount of threshing processed product dropped and supplied to the apparatus also increases the amount of straw scraps mixed in the threshing processed product. In addition to the threshing processed material from the handling chamber, the processed material that is reduced from the sorting unit via the reducing and conveying device is also supplied on the start side of the swing sorting device, so that a large amount of processed material is supplied. Will be. For this reason, when a large amount of processed materials supplied to the swing sorting device are stacked and the processed material layer becomes thick, it takes time for the selection or the accuracy of the selection deteriorates. In addition, the threshing processed product from the handling room contains a relatively large amount of straw debris, but the reduced processing product from the sorting section contains a relatively small amount of straw debris. If the processed material from the sorting unit is mixed, the accuracy and efficiency of sorting will deteriorate accordingly.

  In the above-described conventional threshing machine, the processed product supplied from the handling chamber to the swing sorting device and the processed product reduced from the sorting unit to the swing sorting device are mixed together to thicken the processed layer. There was room for improvement.

  The object of the present invention is to reduce the second processed material from the sorting section to the starting end side of the swing sorting device, but to make the sorting process by the swing sorting device precise and efficient. The purpose is to provide a type threshing machine.

In the first aspect of the invention, the whole of the harvested cereal meal is supplied to the handling room and threshing is performed by a handling cylinder that rotates around the axial center of the threshing machine body, and falls from the receiving net of the handling room. A sorting unit that sorts the threshing processed product while being conveyed backward by the oscillating sorting device, and a second processed product from the sorting unit from the inlet of the side wall of the threshing unit to the start side of the oscillating sorting device In a full-throwing-type threshing machine equipped with a reduction conveying device that discharges to
The handling cylinder is disposed in a state in which the axis of rotation of the handling cylinder is unevenly distributed on the side opposite to the side where the insertion port is located from the center in the lateral direction of the threshing machine body of the oscillation sorting device. Anti-processed material stopper member that suppresses the movement of the processed material in the horizontal direction of the threshing machine body at the sorting operation portion of the sorting apparatus is unevenly distributed on the side where the inlet is located from the center in the horizontal direction of the threshing machine body of the swing sorting apparatus. In this state, the swing sorting device is provided.

That is, since the handling cylinder is arranged in a state in which the axis of the handling cylinder rotation is unevenly distributed on the side opposite to the side where the inlet is located from the center in the lateral direction of the threshing machine of the swing sorting device, Even if the processed product flies in the lateral direction of the threshing machine due to the rotation of the barrel, it spreads as far as possible to the threshing machine body in the lateral direction of the threshing machine and falls, The layer becomes as thin as possible.
Since the handling cylinder and the rocking sorter are eccentric as described above, a wide processing material drop passage is secured between the inlet and the handling chamber in the threshing machine, and the processed material from the inlet oscillates. It is possible to make it fall in a state where it is easy to be sorted and diffused as much as possible to the sorting device. Since the anti-process stopper member is provided in the oscillating sorting device in a state of being unevenly distributed on the side where the inlet is located from the center of the oscillating sorting device in the lateral direction of the threshing machine, it is supplied from the sorting unit to the oscillating sorting device. The reduced processed product and the threshing processed product supplied from the handling chamber to the swing sorting device are difficult to move in the lateral direction of the threshing machine on the swing sorting device because of the anti-process stopper member. It becomes difficult to mix the reduced product.

  Therefore, according to the first aspect of the present invention, the whole of the harvested cereal meal is supplied to the handling room and threshed, and the second processed product from the sorting unit is returned to the starting end side of the swing sorting device. It is possible to efficiently perform the sorting process in a state where the sorting accuracy is high by performing the sorting process while making the treated layer in the swing sorting device as thin as possible and avoiding the mixing of the reduction processed product and the threshing processed product as much as possible.

  In the second aspect of the invention, in the configuration of the first aspect of the invention, the distance between the anti-process stopper member and the center in the lateral direction of the threshing body of the oscillating sorter becomes closer to the lower side in the process transfer direction. It is inclined with respect to the workpiece transfer direction by the swing sorter in a small state.

  That is, the distance between the anti-process stopper member and the horizontal frame of the swinging sorter becomes wider toward the lower side in the process transfer direction, and the processed product that falls between the anti-process stopper member and the sorter horizontal frame is As it is transferred by the rocking sorter, it diffuses in the horizontal direction of the threshing body of the rocking sorter and is easily sorted into grains and dust.

  Therefore, according to the second aspect of the present invention, the processed material falling between the anti-processed stopper member and the horizontal frame of the sorting apparatus is diffused in the lateral direction of the threshing machine body and easily sorted into grains and dust. Therefore, it is possible to perform the sorting process with high accuracy also from this aspect.
