Description

[Detailed description of the invention] Industrial applications The present invention relates to a sorting device for a rice huller.

Problems to be Solved by the Invention The present invention has a rotary sorting cylinder that receives the mixed rice that has been husked at the shedding section and separates it into brown rice and paddy while rotating once, and the thickness of the mixed rice layer in the sorting tube is controlled. A layer thickness detection plate is installed which is connected to a hulling control valve that detects the paddy and adjusts the amount of paddy supplied to the hulling section, and the sorted paddy is dropped to the sorting end of this sorting tube and returned to the hulling section again. For example, in a rice hulling machine of the type where rice grains are removed, as the thickness of the mixed rice layer in the sorting cylinder increases, the layer thickness detection plate interlocks and adjusts the hulling adjustment valve to the side that decreases the thickness of the mixed rice layer. The mixed rice before the amount of paddy supplied to the husking section is adjusted by the valve adjustment has already been transferred to the sorting cylinder, so it takes some time for the thickness of the mixed rice layer to decrease. During this time, the weight is not reduced.As the sorting continues, the amount of brown rice that falls at the end of sorting is large, and the amount of brown rice that is mixed into this reduced paddy is likely to increase. There is a risk that the amount of

Means for Solving the Problem This invention provides a rotary sorting cylinder (1) which separates mixed rice into brown rice and paddy while rotating, and which is rotated according to the thickness of the mixed rice layer supplied into this sorting cylinder (1). Layer thickness detection Fi (
Φ, and the sorting start supply port 6) of the sorting tube (1) which receives the mixed rice layer scooped up by the rotation of the sorting tube (1).
This sorting device for a huller is provided so as to automatically adjust the mixed rice sorting area by integrally rotating the mixed rice sorting plate (1) and the mixed rice sorting plate (1) for reducing the rice.

Functions and Effects of the Invention The paddy supplied to the husking section (21 is husked in the husking section, and this mixed rice of brown rice and paddy is passed from the sorting start supply port G of the rotary sorting tube (1)) to the sorting tube. (1) to form a mixed rice layer, which is transported towards the end of sorting, and is also scooped up in the rotating direction of the sorting tube (1), and the lowest layer of brown rice is collected and transferred to the outside of the sorting tube (D). After being taken out, the mixed rice in the middle layer is collected to be returned to the sorting start supply port c)), and the paddy in the upper layer falls from the sorting end section and is again returned and supplied to the husking section.

In addition, along with these actions, when the thickness of the mixed rice layer in the sorting tube (D increases), the layer thickness detection plate (■) rotates according to this layer thickness, and controls the hulling adjustment valve (■) in the direction of decreasing the amount of paddy supplied. At the same time, the mixed rice sorting plate (6) is rotated at the same time to receive more of the mixed rice at the sorting end that has been scooped up by the sorting tube ■, thereby making the mixed rice layer at the sorting end thinner. As a result, the amount of brown rice mixed in the reduced paddy that falls from the front end of the sorting tube (1) decreases, and as a result, the amount of mixed rice in the sorting tube (1) decreases as the amount of paddy supplied to the hulling control valve (3) decreases. Even while the layer thickness decreases, the amount of brown rice mixed in the reduced paddy can be reduced and stable sorting can be maintained at all times.
