Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a mount for a thrower for discharging unsorted brown rice from a hulling sorter to the outside of the machine.

BACKGROUND TECHNOLOGY Conventionally, in a hulling sorting machine having a dehulling section, a wind sorting section, a swing sorting section, etc., a thrower is often used as a means for discharging finished brown rice. This is mainly a request from a cost perspective, but on the other hand, from the perspective of producing high-quality rice, it is better to use a bucket elevator, which has less impact on the brown rice because it does not reduce the quality of the brown rice.

Problems that the invention aims to solve Therefore, in order to meet the above needs, in addition to the thrower type huller sorter, a bucket elevator type one is manufactured. A dedicated mount for the elevator was required, further increasing costs.

This invention provides a mounting base for a brown rice thrower in a huller sorting machine that can be easily mounted using the brown rice thrower mounting base without requiring a special mounting base when installing a brown rice bucket elevator. is a technical issue.

Means for Solving the Problems In order to solve the above-mentioned technical problem, the mounting stand for the brown rice thrower in the rice hulling sorting machine according to the present invention connects the brown rice flow path from the oscillating sorting section to the thrower communication port. It has a thrower discharge gutter running vertically to reach the bucket elevator, and a bucket elevator discharge gutter running horizontally connecting to the brown rice flow path and reaching the bucket elevator connecting port, the thrower discharge gutter and the bucket elevator. A valve for switching between the two discharge gutter is provided at the intersection with the drain gutter, and a rotary shaft is protruded and supported near the thrower communication port, and a thrower blade or brown rice bucket is attached to the rotary shaft. It is designed to pivot a pulley that drives an elevator.

As a result, the brown rice thrower is removed from the brown rice thrower mounting base, and a pulley that drives the brown rice bucket elevator is attached to the brown rice bucket elevator in place of the thrower blade that is pivoted on the rotating shaft, and the brown rice thrower is attached to the brown rice bucket elevator connection port. The brown rice bucket elevator is installed by aligning the supply port of the brown rice bucket elevator with the supply port, and the pulley and the lower shaft pulley of the brown rice bucket elevator are connected with a belt, and the thrower discharge gutter is connected to the lower shaft pulley of the brown rice bucket elevator. By operating the valve to the closing side, the flow path from the brown rice flow path to the brown rice bucket elevator is opened and the brown rice is discharged.

The scraped rice in the tank 8 is evenly fed to a swing sorting board 9 installed in multiple stages and is sorted into paddy and brown rice. And partition plate 1
The paddy, brown rice, and mixed grains of paddy and brown rice partitioned by 0 and 11 are separated by paddy flow path 12 and brown rice flow path 1, respectively.
3. The paddy is guided down the mixing channel 14 and is returned to the deroller 3 by the paddy thrower 16, and the mixed grains pass through the screw conveyor 6, the bucket elevator 7, and the tank 8 before being sent to the oscillating sorting board. The brown rice is subjected to a sorting action at 9, and the brown rice is transferred to a brown rice thrower 23 attached to a brown rice mount 18 or a bucket elevator 16 for brown rice.
is ejected from the aircraft.

Regarding the discharge of brown rice mentioned above, brown rice thrower 24
