Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a hulling and sorting device that removes paddy in a huller and then separates and extracts only brown rice from the removed rice after the removal. It is something.

[Conventional technology and its problems]

Conventionally, this type of rice hulling sorting equipment has generally adopted a swinging type sorting mechanism for sorting brown rice, but this swinging type sorting mechanism is large and suffers from vibrations and Since it has drawbacks such as large noise, Japanese Patent Application Laid-open No. 49-24745 as a prior art proposes a horizontal rotation system with many recesses formed on the inner circumferential surface for sorting brown rice from mixed rice after removal. It is proposed to use a rotary sorting mechanism consisting of a brown rice catcher installed in the sorting barrel.

The rice hulling and sorting device described in this publication supplies the rice grains removed from the huller together with the rice husks into the sorting barrel of the rotary sorting mechanism, and the rice husks in the rice grains are removed from the grains in the sorting barrel. However, in the rotary sorting mechanism, the fallen rice supplied into the sorting cylinder is scraped up to a certain height by the rotation of the sorting cylinder, and then it is collected at the bottom. As it moves to the discharge side while repeating the falling flow and forming a fluidized bed, the brown rice among the rice that has fallen down is stuck in the recess and is lifted up to a relatively high position, and then falls down and is moved to the discharge side. Utilizing the movement of the paddy falling from a lower position than the brown rice, the brown rice falling from a higher position is caught in the brown rice catcher and taken out. Sorting the rice husks by suction together with the wind changes the flow state and lifting height of the fallen rice in the sorting barrel, and some of the rice husks that could not be suction-sorted enters the recesses, causing Since the number of entering brown rice is reduced, the sorting accuracy and sorting ability for brown rice are reduced.

Therefore, in order to solve this problem, it is possible to wind-select the rice that has been removed from the rice to remove the chaff, and then feed it to the rotary sorting mechanism. A rice wind sorting section and a rice grain lifting mechanism for transporting the fallen rice that has been wind-sorted in the rice sorting section to a rotary sorting mechanism are required.

Furthermore, in order to remove the paddy discharged from the discharge section of the rotary sorting mechanism again at the hulling section, a hulling mechanism is required to transfer the paddy to the hulling section.

Moreover, since the brown rice sorted by the rotary sorting mechanism contains a large amount of dust such as bran generated by the rotation of the sorting cylinder, a brown rice winding section is provided to remove this dust from the brown rice. is necessary.

That is, in a hulling sorting device that uses a rotary sorting mechanism to sort brown rice from the scraped rice after shedding, as described above, the scraped rice sorting section, the scraped rice lifting mechanism, and the unhulled In addition to the necessity of a grain mechanism and a brown rice wind sorting section, a power transmission mechanism to the above-mentioned scraped rice lifting mechanism and hulling mechanism is also required, which makes the hulling and sorting mechanism significantly large. Ta.

The present invention provides a hulling sorting device that uses a rotary sorting mechanism to sort brown rice from scraped rice after shedding. By specially devising the arrangement of the wind selection section, the device was made smaller and lighter.

A sliding rice lifting mechanism for transferring fallen rice to the rotary sorting mechanism and a paddy lifting mechanism for transferring paddy in the paddy receiving trough to the paddy supply tank are connected to the box-shaped machine frame. The structure is such that the sliding rice-lifting mechanism is located on the outside and the paddy-hulling mechanism is located on the inside at one side of the structure.

[Effect]

In this configuration, the paddy supplied to the paddy supply tank is removed by the huller, and then wind-selected to remove the chaff by the sliding rice winding section below. is fed into the sorting cylinder in the rotary sorting mechanism.

The fallen rice thus supplied into the sorting cylinder of the rotary sorting mechanism is lifted up to a certain height by the rotation of the sorting cylinder, and then falls down, moving towards the paddy discharge section while repeating the flow. In the meantime, the brown rice in the rice that has been washed down is sorted to enter the brown rice receiving trough, and the brown rice that has entered the brown rice receiving trough is wind-selected in the brown rice winding department to remove dust such as bran. While being discharged outside the machine, the unhulled rice is
After the paddy is discharged from the paddy discharge part in the sorting barrel into the paddy receiving trough, it is transferred to the paddy supply tank via the paddy lifting mechanism and removed again.
