Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a rotary sorting type huller for sorting mixed rice of paddy and brown rice using a rotating sorting tube having a large number of pot holes in its inner surface. It's about machines.

[Prior art]

There is a rotary sorting type huller that sorts a mixed rice of paddy and brown rice by rotating a rotary sorting cylinder, which has a large number of pot holes on its inner circumferential surface, around a horizontal axis.

Japanese Patent Publication No. 1-41384 as the prior art,
The structure is such that the dropped rice after shedding and wind sorting is fried by a dropped rice thrower to the dropped rice transfer gutter in the sorting cylinder, and the thrown rice from the dropped rice thrower that is generated during lifting of dropped rice is It is proposed to reduce the flow velocity by causing the wind to collide with the spiral blades of the spiral conveyor in the fallen rice transfer gutter. That is, the dropped rice thrower is installed approximately parallel to the side plate of the hulling mechanism in the cover case covering the sorting cylinder, and the upper end outlet of the dropped rice thrower is located in the lower space of the paddy supply hopper, and the thrower wind The structure is such that a portion of the dropped rice transfer gutter near the outer periphery of the spiral conveyor is exposed to the inside of the dropped rice transfer machine so as to be ejected approximately along the axial direction of the spiral conveyor.

[Problem that the invention seeks to solve]

When the mixed rice that has been subjected to the husking and winnowing process is fried by the sliding rice thrower and is fed to the spiral conveyor of the sliding rice transfer trough, the l? v In the method of reducing the flow velocity by directly colliding the throat wind from the end exit of the rice thrower and the grains thrown out at the same time with the spiral blades of the spiral conveyor, the throat wind flowed by the rice thrower is There is a problem in that when sprayed onto the spiral blade, it is diffused in the outer circumferential direction and adversely affects sorting.

Therefore, the present invention eliminates the diffusion of the thrower wind as in the prior art when transferring the grains fried by the sliding rice thrower and the thrower wind to the mixing rice helix of the mixing rice gutter on the side of the rotating sorting cylinder. This aims to improve the sorting accuracy in the -1-turn sorting tube by preventing the influence of the thrower wind on the grains to be sorted.

[Means for Solving the Problem] The technical means of the present invention for solving such technical problems is that a large number of pot holes 9, 9°, etc. are formed on the inner peripheral surface, and the horizontal axis Finished rice 916 for receiving brown rice is placed horizontally in the rotary sorting tube 11 that rotates around, and inside the rotary sorting tube 11,
A mixed rice gutter 14 that supplies mixed rice to the sorting start end side of the rotary sorting cylinder 11 is horizontally suspended along the finishing rice gutter 16, and this mixed rice v
In #14.

A mixed rice helix 13 is provided to convey grains to be sorted from the sorting end side to the sorting start side of the rotary sorting cylinder 11, and this mixed rice gutter 1
The rotary sorting type huller is characterized in that a helical wind guide plate 17 is provided near the conveyance start end of the mixed rice helix 13 in No. 4 to receive the grains fried by the sliding rice thrower 8 and the thrower wind. The configuration is a mixed rice feeding device.

[Operations and Effects of the Invention] The mixed rice that has been shed in the shedding section 1 and wind-selected in the sliding rice wind selection path is fried in the sliding rice thrower 8, and the mixed rice helix 13 in the mixing rice gutter 14 is The grain is fried to the starting end. At this time, the mixed rice and thrower wind are controlled by a spiral wind guide plate 17 provided near the conveyance start end of the mixed rice spiral 13 in the mixed rice gutter 14.
It is possible to reduce the blower wind being received and decelerated by the rotary sorting tube 11 from being diffused into the pot hole 9 portion on the outer periphery of the rotating sorting tube 11, and to reduce the adverse effects of sorting in the rotating sorting tube 11.

In addition, since the spiral wind guide plate 17 prevents the thrower wind from flowing in the axial direction of the mixed rice spiral, it prevents dust, etc. from being spread in the longitudinal direction in conjunction with the spiral wind.
This can prevent dust etc. from getting mixed into the finished rice.

The discharge side end of the finishing rice trough 16 is communicated with the finishing rice receiving trough 19 via the finishing rice grain board 18, and the brown rice falls from the finishing rice grain board 18 to the finishing rice receiving trough 19. The brown rice that was wind-selected during the process and flowed down to the finished rice volume @19 is transferred to the finished rice grain lifting machine 20.
It is taken out of the machine via the

Reference numeral 21 denotes a pumping cylinder which is integrally provided at the sorting end of the rotary sorting cylinder 11, and the grains after sorting that flow into the pumping cylinder 21, that is, the grains mainly consisting of unhulled rice, are pumped up. The structure is such that the paddy is returned to the hulling section via the paddy reduction @22.

Next, the mixed rice gutter 14 will be explained. This mixed rice gutter 1
A mixed rice helix 13 is provided at the bottom of the rotary sorting cylinder 11 for conveying the rice from the sorting end side, that is, the side close to the shedding section 1, to the sorting starting end side, that is, the side away from the shedding section 1. Furthermore, the feeding portion 13a of the mixed rice spiral 13 in the mixed rice gutter 14 is provided with a spiral-like guide plate 17 that can be opened and closed in the vertical direction.

In this embodiment, the thin helical guide plate 17 is provided only above the mixed rice helix 13, but it may also be a helical guide plate with the right and left sides closed.

Next, the operation of the embodiment will be explained.

When carrying out hulling work, supply the rice to the paddy tank 2,
Drives each rotating part of the huller. Then.

The paddy supplied from the paddy tank 2 to the dehulling rolls 3, 3 is subjected to the dehulling action, and the scraped rice is fed downward to the scraping rice wind sorting path 4 where it is wind sorted, and the rice husks are sent to the dust exhaust pipe 6. The waste is ejected out of the aircraft. In addition, the mixed rice of brown rice and paddy is supplied dropwise to the amount of crushed rice @ 7 and fried in the crushed rice thrower 8 . The mixed rice fried by the sliding rice thrower 8 and the thrower wind are transferred to the spiral wind guide plate 17 provided in the supply section 13a of the mixed rice spiral 13.
After being received by and decelerated, the mixed rice is guided as indicated by the two-dot chain arrow in FIG. 2 and is supplied to the mixed rice helix 13 in the mixed rice 1114.

In this way, after the grains and the thrower wind are received by the spiral wind guide plate 17, the mixed rice is fed to the mixed rice spiral 13 of the mixed rice@14, so the thrower wind is decelerated and the grains are directed to the outer circumferential side of the rotating sorting cylinder 11. Can prevent widespread spread.

In addition, dust etc. may enter the pot holes 9, 9° of the rotating sorting tube 11...
When the grains enter the rotary sorting tube 11, the grains are no longer scraped up by the rotary sorting tube 11, so the sorting efficiency decreases.
When the brown rice is reduced and subjected to the depurifying action again with the depurating roll 3°3, it becomes twice-printed.

This causes a decline in the quality of brown rice. However, by providing the helical wind guide plate 17, it is possible to prevent the wind from reaching the wide area of the pot holes 9, 9°... on the outer periphery of the rotating sorting tube 11, and the dust attached to the mixed rice gutter 14 can be prevented. etc., from adhering to the pot holes 9.9, . . . of the cylindrical sorting tube 11.

Note that this helical style guide plate 17 is configured to be able to freely rotate in the vertical direction, so by rotating it upward, it is possible to easily clean the mixed rice helical 13 and the supply section 13a. be.
