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 of paddy and brown rice by rotating a rotary sorting cylinder, which has a large number of potholes on its inner peripheral surface, around a horizontal axis. Inside this rotary sorting cylinder, a return shelf is installed obliquely in the middle part in the longitudinal direction from the supply side to the discharge side below the finished rice gutter, and the grains pumped up by the rotary sorting cylinder are stored in the upper finished rice gutter. The grains that do not reach the top, that is, the grains mixed with a relatively large amount of brown rice that have been pumped up to the top, are guided down from the upper rotation side of the rotary sorting tube to the lower rotation side of the rotation sorting tube, and are formed by the rotation of the rotary sorting tube. The grains to be sorted are returned to the lower side of the rotational direction of the fluidized bed than the lower side of the rotational direction, increasing the chance of the grains, which are mixed in with brown rice in large numbers, to fit into the pot hole. The efficiency of collecting finished rice into the gutter is increased.

[Problems to be solved by the invention] However, in this conventional loading system, the reduction shelf is fixedly arranged below the finished rice trough, so the amount of grains to be sorted in the rotary sorting cylinder is Due to an increase or decrease in the number of grains, the layer thickness and pumping height of the fluidized bed formed by the rotation of the rotary sorting cylinder will change, and if the amount of grains to be sorted is large, a large amount of grains with a low brown rice ratio will flow down and be returned. Moreover, when the amount of grains to be sorted is small, only a small amount of grains are returned downstream, and the function of the reduction shelf is not fully demonstrated.

In view of this, the present invention provides that even if the layer thickness and pumping height of the fluidized bed formed by the rotation of the rotary sorting tube change due to an increase or decrease in the amount of grains to be sorted in the rotary sorting tube, the grains to be sorted will By changing the position of the reducing machine up and down in relation to increases and decreases in the amount, it is possible to maintain a predetermined relationship between the reducing machine and the fluidized bed of grains to be sorted, thereby improving the function of the reducing machine. .

[Means to solve the problem]

The technical means of the present invention for solving such technical problems is to horizontally suspend the finishing rice gutter 16 in a rotary sorting cylinder 11 which has a large number of potholes formed on its inner circumferential surface and rotates around a horizontal axis. The finishing rice trough 16 is provided obliquely below at least the middle of the finishing rice trough 16, and is located above the inside of the grains pumped up by the rotating sorting cylinder 11. The reducing machine 23 receives the grains that have not reached the grains and guides them down to the rotationally lower side of the rotary sorting tube 11.
The grain sorting device is configured such that the grains to be sorted are vertically movably supported via a support plate 24 supported on the surface of a fluidized bed of grains to be sorted.

[Function and effect of the invention]

When performing five sorting operations in the rotary sorting tube 11, the Wj thickness and pumping height of the fluidized bed formed by one rotation of the rotary sorting tube 11 change due to an increase or decrease in the amount of grains to be sorted in the rotary sorting tube 11. Even if I do.

Since the reducing machine 23 is supported in a vertically movable manner via a support plate 24 supported on the surface of the fluidized bed of the grains to be sorted in the rotary sorting tube 11, the layer thickness of the fluidized bed of the grains to be sorted changes. The upper end of the reducing machine 23 is kept at a predetermined distance from the surface of the fluidized bed. That is, the grains pumped up to the top and containing a relatively large amount of brown rice are guided downward from the upper rotation side of the rotary sorting tube to the lower rotation side of the rotary sorting tube, and the grains with a high proportion of brown rice are collected in the rotary sorting tube 1.
This increases the chances of fitting into the pot hole No. 1 and improves the sorting efficiency.
