Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is implemented in a hulling machine that sorts mixed rice of paddy and brown rice using a rotating sorting tube that has a large number of pot holes on its inner circumferential surface. can do.

[Prior art] The grain sorting device is equipped with a husking section and a grain sorting device that rotates a rotary sorting tube, which has a large number of pot holes on its inner circumferential surface, around a horizontal axis to sort out mixed rice of paddy and brown rice. There is a rice hulling machine that does this. and,
This finishing rice gutter is installed inside the rotating sorting cylinder, and the amount of grains to be sorted is detected by a layer thickness detector installed on the supply side of the rotating sorting cylinder. If there are many,
There is a system in which the amount of grain supplied to the rotary sorting cylinder is controlled to be reduced by reducing the supply amount of the paddy supply control valve on the hulling section side, thereby optimizing the amount of grains to be sorted by the rotary sorting tube.

In this type of huller, the flow of grains to be sorted from the supply side to the discharge side in the rotary sorting cylinder may be poor due to differences in the variety of grains to be sorted or differences in dryness. In some cases, the inclination of the discharge side of the one-turn sorting cylinder is adjusted to be lower, thereby improving the flow of the grains to be sorted and improving the sorting efficiency.

[Problem to be solved by the invention] However, if the rotary sorting tube is tilted like this.

There is a change in the interlocking relationship between the layer thickness detector and the paddy supply control valve of the shedding section, and the paddy supply control valve is adjusted to the closed side, reducing the amount of paddy supplied to the shedding section, and as a result, the rotation There was a problem in that the supply of grains to be sorted to the sorting cylinder was reduced, and the sorting efficiency was lowered.

Therefore, in this invention, the flow of the grains to be sorted from the supply side to the discharge side in the rotary sorting tube becomes poor due to differences in the variety and dryness of the grains to be sorted in the rotary sorting tube. Even if the inclination of the discharge side of the cylinder is adjusted to be lower to improve the flow of the grains to be sorted and improve the sorting efficiency, the layer thickness detector on the rotary sorting cylinder side and the paddy supply at the husking section The purpose is to prevent the interlocking member with the control valve from being adjusted to the closing side of the paddy supply control valve, maintain the appropriate opening degree of the paddy supply control valve, and improve sorting efficiency. .

[Means to solve the problem]

The technical means of the present invention for solving such technical problems is that a removing part 1 and a rotary sorting cylinder 11, which has a large number of pot holes on its inner peripheral surface and rotates around a horizontal axis, are housed inside. The sorting case 10 is arranged in close proximity to the rice, and the scraped rice after the dehulling process in the dehulling section 1 can be supplied to the rotary sorting tube 11. A layer thickness detection tool 25 located in the sorting cylinder 11 and movable up and down as the amount of grains to be sorted increases or decreases is supported via a layer thickness detection shaft 26 which is pivotally supported in one sorting case 10. , the paddy supply control valve 31 of the husking section 1 is configured to be able to be opened and closed freely, and the layer thickness detection device 25
In interlocking and connecting the paddy supply control valve 31 with the paddy supply control valve 31, the vertical support part 28a is connected to the paddy supply control valve 31 side and
The longitudinal sliding linkage part 28b of the first interlocking rod 28 rotates about
8b and a layer thickness side linking member 27 that slides in a non-linked manner and links only the rotational movement about the axis of the layer thickness detection shaft 26. The structure is a valve control device.

[Function and effect of the invention]

When performing sorting work in the rotary sorting tube 11, while detecting the amount of grains to be sorted in the rotary sorting tube 11 with the layer thickness detector 25, the amount of grains to be sorted is detected on the husking section 1 side in response to an increase or decrease in the amount of grains to be sorted. Adjust the opening degree of the paddy supply control valve 31 to the closed side or the open side,
The amount of grains to be sorted into the rotary sorting tube 11 is controlled to the decreasing side or the increasing side, and the hulling and sorting work is performed while maintaining the amount of grains to be sorted in the rotary sorting tube 11 appropriately, and,
If the flow from the supply side of the rotary sorting cylinder 11 to the discharge side is poor due to differences in the degree of dryness of the grains to be sorted or differences in the varieties, adjust the tilt of the sorting case 10 to increase the flow from the supply side of the rotary sorting cylinder 11. When the inclination is adjusted so that it is positioned upward, the layer thickness detection shaft 2 on the sorting case 10 side supporting the layer thickness detection tool 25
6 also tilts and moves together with the sorting case 10, but the layer thickness detecting tool 25 and the paddy supply regulating valve 31 are connected to the paddy supply regulating valve 31 side, and rotates about the vertical support part 28a as a fulcrum. When the layer thickness detection shaft 26 on the side of the layer thickness detection shaft 26 is moved in the longitudinal direction, the longitudinal direction sliding linkage part 28b of the first interlocking rod 28 slides with the longitudinal direction sliding linkage part 28b, and the layer thickness is uncoupled. Since the layer thickness detection shaft 26 is linked via the layer thickness side linking member 27 that only links the rotational movement about the axis of the detection shaft 26, the movement of the layer thickness detection shaft 26 based on the tilt movement of the first sorting case 10, Since the opening degree of the paddy supply control valve 31 on the side of the husking section 1 is not adjusted, the grains to be sorted before the tilt adjustment of the rotary sorting tube 11 are supplied to the rotary sorting tube 11, so that an appropriate amount of grains to be sorted can be obtained. It is possible to maintain this and improve the sorting efficiency.
