Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is composed of a rotating sorting tube or the like having a large number of pot holes on its inner circumferential surface, and is used to sort mixed rice of paddy and brown rice. The present invention can be used in a hulling sorter having a mixed rice sorting section and a hulling section, and relates to a helical grain lifting device for a hulling sorter.

[Prior art and problems to be solved by the invention] A hulling and sorting machine equipped with a hulling section for removing the hull, a wind sorting section for wind-selecting the scraped rice from the hulling section, and a mixed rice sorting section. At the same time, the fallen rice after wind sorting from the threshing section is transferred to the mixed rice sorting section using a spiral grain-lifting type mixed rice lifting machine, and the brown rice sorted in the mixed rice sorting section is transferred to the mixed rice sorting section. Some brown rice grains are taken out of the machine.

However, in this conventional device, the upper end of the mixed rice fryer and brown rice fryer protrudes from the upper end of the machine body when it is aligned in the longitudinal direction, and is When transported by air, it takes up a lot of space and has the drawbacks of damaging the mixed rice and brown rice lifting machines that protrude from the fuselage. Therefore, the present invention attempts to eliminate such drawbacks.

[Means to solve the problem]

The technical means of the present invention for solving such technical problems consists of a husking section 1. In a hulling sorting machine that is equipped with a wind sorting section that wind-sorts the rice that has fallen from the hulling section 1 and a mixed rice sorting section, the rice that has been slipped off from the shelling section 1 and has been wind-sorted in the wind-selection section is mixed. A spiral grain type mixed rice lifting machine 8 that lifts rice to a mixed rice sorting section, and a brown rice lifting machine 20 that takes out brown rice sorted in the mixed rice sorting section out of the machine are installed on the side of the machine. established in
The mixed rice grain lifting machine 8 and the brown rice grain lifting machine 20 can be placed in a state in which the upper end protrudes from the machine body in a vertical direction, or in a state in which they are housed in a horizontal direction from the top, bottom, front and rear edges of the machine body in a lateral side view. The structure of the helical husking device of the rice huller sorting machine is characterized by its ability to change its position.

[Operations and Effects of the Invention] During the hulling and sorting work, the upper end of the spiral type mixed rice grain lifting machine and the spiral type brown rice grain lifting machine protrudes upward from the hulling machine body, and The scraped rice after wind sorting in step 1 is fried and supplied to the mixed rice sorting section by a spiral vIJ grain type mixed rice lifting machine 8, where it is sorted into unhulled rice and brown rice. In addition, the brown rice after being sorted in the mixed rice sorting department is
It is taken out of the machine by a helical type brown rice lifting machine 20, and when transporting the huller and sorting machine, the mixed rice lifting machine 8 and the brown rice lifting machine 20 are vertically moved at their upper ends. From the state in which the parts protrude upward from the hulling machine body, the ends of the mixed rice grain lifting machine 8 and brown rice grain lifting machine 20 are housed inward from the upper and lower front and rear ends of the hulling machine body by rotating laterally. By changing the position to the state of
This reduces the possibility of the end of the vehicle colliding with obstacles, thereby reducing damage.
