Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a grain sorting device for sorting mixed rice of paddy and brown rice using a rotating sorting cylinder having a large number of potholes on its inner peripheral surface. It is something.

[Prior art]

There is a grain sorting machine that sorts a mixed rice mixture of paddy and brown rice by rotating a rotary sorting tube, which has many potholes on its inner circumferential surface, around a horizontal axis. Inside this rotary sorting cylinder, a reduction shelf is installed diagonally below the finished rice gutter from the longitudinal middle part to the discharge side, so that the grains drawn up by the rotary sorting cylinder do not reach the upper finished rice gutter. The grains, that is, the grains containing a relatively large amount of brown rice, are guided down from the upper rotating side of the rotating sorting tube to the lower rotating side, and the flow of grains to be sorted is formed by the rotation of the rotating sorting tube. The flow is returned to the lower side of the rotational direction than the lower side of the layer in the rotational direction, increasing the opportunity for grains mixed with a relatively large amount of brown rice to fit into the pot holes, increasing the efficiency of collecting brown rice into the finishing rice gutter. ing.

[Problem that the invention seeks to solve]

However, in this conventional device, a return shelf is provided below the finishing rice gutter over the entire width in the longitudinal direction, and is tilted from the upper side of the rotation to the lower side of the rotation of the rotating sorting section, and the entire amount of grains received is transferred to the lower side of the rotation direction. It is being returned downstream. For this reason, even the grains mixed with a relatively large amount of paddy received at the discharge side end of the return shelf are returned from the lower end of the return shelf to the lower side in the rotational direction of the rotary sorting cylinder, so the paddy mixture ratio is reduced. There was a problem in that the unhulled rice in the grains with high grains was drawn into the pot hole of the rotary sorting cylinder and was drawn up, and the unhulled rice fell into the finishing rice trough above, reducing the sorting accuracy.

Therefore, the present invention makes the grains flowing down from the discharge side end of the rotary sorting tube in the reduction shelf quickly flow to the discharge side of the rotary sorting tube, and removes the grains mixed with a large amount of unhulled rice from the rotary sorting tube. This is intended to improve the sorting accuracy by quickly discharging the waste from the discharge side.

[Means to solve the problem]

The technical means of the present invention for solving such technical problems is to construct a finishing rice gutter 16 for receiving brown rice in a rotary sorting cylinder 11 which has a large number of potholes in its inner peripheral surface and rotates around a horizontal axis. At a lower position of the finished rice machine 16 in the rotary sorting cylinder 11, there is a rotating upper part of the rotary sorting cylinder 11 that receives grains that do not reach the finished rice @16 in the upper part of the grains drawn up by the rotary sorting cylinder 11. A reduction shelf 23 is installed diagonally to guide the flow downward from the side toward the lower side of the rotation, and the rotary sorting tube 11 on the reduction shelf 23 is
In a portion corresponding to the discharge side end of the rotary sorting tube 11, there is a discharge direction guide surface which is inclined so that the supply side for guiding the grains flowing down to the discharge side of the rotary sorting tube 11 is positioned at the upper side and the discharge side is positioned at the lower side. 24 is adopted as the structure of the reduction shelf of the grain sorting device.

[Function and effect of the invention]

When performing sorting work in the rotating sorting tube 11, the brown rice that has been pumped up high through the pot hole of the rotating sorting tube 11 falls into the finishing rice gutter 16 located above and is sorted, and the paddy rice and some brown rice that have been pumped up low are passed through the rotating sorting tube. Also, grains that do not reach the finishing rice trough 16 in the upper part of the grains drawn up through the pot hole of the rotary sorting cylinder 11, that is, grains that are mixed with a relatively large amount of brown rice, are It is received by the reduction 41123 and guided downward from the rotationally upper side of the rotary sorting cylinder 11 to the rotationally lower side, so that it is lower in the rotational direction than the part of the fluidized bed of grains to be sorted formed by the rotation of the rotary sorting cylinder 11 on the lower side in the rotational direction. By returning the grains to the downstream side, grains with a relatively large amount of brown rice are allowed to fit into the pot hole, increasing the efficiency of collecting brown rice into the finishing rice trough 16 and proceeding with sorting. At the discharge side end of the shelf 23, there is a rotary sorting tube 1 for sorting grains flowing down.
Since the discharge direction guide surface 24 is configured to be inclined so that the supply side guiding to the discharge side of No. 1 is located at the upper level and the discharge side is located at the lower position, the grains flowing down the discharge side end of the return shelf 23 are The grains are quickly guided down to the discharge side of the rotary sorting tube 11 by the discharge direction guide surface 24, reducing the chance that grains with a high proportion of unhulled rice will fit into the pot hole of the rotary sorting tube 11,
It is possible to improve the sorting accuracy by reducing the chances of pumping unhulled rice to the finishing rice gutter 16.
