Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a grain sorting device for sorting mixed rice such as paddy and brown rice using a rotating sorting tube having a large number of potholes on the inner circumferential surface. It is related to.

[Prior art]

In a conventional grain sorting device that sorts mixed rice such as paddy and brown rice using a rotary sorting tube with a large number of potholes on the inner circumferential surface, grains after sorting are stored in the rotary sorting tube. Multiple grain troughs were installed to receive the grain. This has the disadvantage that the configuration, transmission mechanism, etc. are complicated.

[Problem that the invention seeks to solve]

Therefore, the present invention attempts to simplify the structure and reduce costs by performing the grain sorting operation using a single grain gutter specially constructed within the rotary sorting cylinder.

[Means to solve the problem]

The technical means of the present invention to solve this technical problem is to arrange one grain gutter α■ in a rotating sorting cylinder (11) which has a large number of potholes on its inner circumferential surface. , the grain trough a
3 is divided into two parts in the middle, the supply side of the rotary sorting tube (11) is made into the supply gutter αQ with the supply helix a4, and the rotary sorting tube (11) is divided into two parts.
The discharge side of 1) is the finishing rice gutter αη with the finishing rice helix αe.

[Action/effect of the invention]

One grain gutter (
13) is divided into two parts in the middle, and one part is used as a supply gutter (l) with a supply helix α, and the other part is used as a part with a finishing rice helix αQ and a mallet Q′i. The grain gutter A3 with the helical transfer device can be made into a single one, and its transmission structure can be simplified, thereby reducing costs. An example will be explained. First, to explain the configuration of the embodiment, (1) is as follows:
The shedding section (1) consists of a paddy tank (2), a pair of shedding rows/I/(3), (3), etc.

(4) is the Surirakumaikaze path, and the suction fan room in front (5)
The rice husks are removed from the shedding section (1) by the sorting air generated by the rice crackers, and the rice husks are transferred from the suction fan chamber (5) to the dust exhaust pipe (
6), the mixed rice of brown rice and paddy falls into the sliding rice receiving trough (7) below, and the mixed rice that has fallen into the sliding rice receiving trough (7) is used for mixed rice frying. Grain machine (8) rotates sorting tube (1)
1) It is configured to be transported to the side. QO is a sorting case, and inside the sorting case αQ, there is a supply side end (- No. (right side in figure 1)
and the drive roller (2
) and @ are rotatably supported.

A single grain side (13) is suspended horizontally in this rotary sorting tube (0]), and this supply gutter (13) is partitioned in the middle by a partition (13a).
)' is divided into two parts, and the grain-side portion located on the supply side of one rotary sorting tube aυ is transferred toward the supply side end of the rotary sorting tube aυ.→ There is a finishing rice helix αQ that transfers the part of the grain side αJ located on the discharge side of the rotary sorting tube (11) to the discharge side end of the rotary sorting tube aυ. Finishing rice gutter a
't).

The output port (8a) of the mixed rice lifting machine (8) connected to the dropped rice receiving gutter (7) is extended to the middle part of the rotary sorting cylinder (11), and the feeding gutter (to) is conveyed. It is configured to be able to supply mixed rice to the starting end side. When connecting the output port (8a) of the mixed rice frying machine (8) to the conveyance start end side of the supply gutter (C), rotate the grain side (to) and the rotary sorting cylinder (11) from below to above. The grain side α
It is also possible to connect the tube G with the part of the rotary sorting tube (11) that rotates from the top to the bottom.

Also, between the finishing rice gutter α force and the part of the rotating sorting tube (11) rotating from the bottom to the top, there is a rotating sorting tube (11).
A mixing rice gutter (toward) is installed that slopes low toward the discharge side end of the rice mixing gutter, and the lower end of the mixed rice gutter is passed through the mixed rice flow down tube a* to the fallen rice receiving gutter ( 7).

A finishing rice control valve (17a) is installed at the upper end of the finishing rice gutter (11).
) is rotatably supported on the shaft so that the receiving area of the finishing rice gutter (11) can be adjusted freely, and the upper part of the supply gutter (to) is equipped with a 0υ pot hole in the rotary sorting tube. A guide plate for receiving finished rice and allowing it to flow down to the finishing rice gutter Qη on the discharge side of the rotary sorting tube (11) is provided, and a guide plate is provided at the discharge side end of the finishing rice gutter (11). is configured so that the finished rice can flow down to the finished rice receiving gutter (2) via the finished rice flow lower tube QD and the finished rice flow grain board @, and the brown rice that has flowed down to the finished rice receiving gutter (to) is This is what is taken out of the grain machine (c).

A paddy lifting cylinder (
A paddy return gutter (E) is installed below the grain pumping cylinder (C), and the paddy is pumped up by the paddy lifting cylinder (C). The paddy after sorting is returned to the shedding section (1) via the paddy return gutter (E).

Next, to explain the operation of the embodiment, when carrying out the hulling work, the raw wire is supplied to the rice tank (2), and each rotating part of the hulling machine is operated. drive Then, the paddy supplied from the paddy tank (2) to the shedding section (1) is subjected to the shedding action, the fallen rice is sorted in the downward sliding rice wind sorting channel (4), and the rice husks are transferred to the suction fan room. (5) and is discharged from the dust exhaust pipe (6) to the outside of the machine.

The mixed rice of brown rice and paddy after wind selection falls into the sliding rice catcher (7), is fried by the mixed rice lifting machine (8), and is fed from the outlet (8a) to the feeder a! 9 is supplied to the conveyance start end side,
The rotating sorting cylinder (11) is rotated by the supply helix α in the supply gutter (11).
) is supplied to the supply end of the

Next, the mixed rice is washed through the pot hole of the rotary sorting tube (11) rotating clockwise in Figure 2, and the fine brown rice is passed through the finished rice flow guide plate (a) and the finished rice gutter αη. The rice mixed with paddy and some brown rice falls into the upper open supply gutter 0Q and the mixed rice gutter (G), and the mixed rice that falls into this feed gutter Q5 is transported by the feed helix α→ The mixed rice that is supplied to the rotary sorting tube 0v and falls into this mixed rice gutter (to) further passes through the mixed rice flow lower tube α, and is transferred to the fallen rice receiving gutter (
7), is fed again to the supply gutter aS by the mixed rice frying machine (8), and subjected to the sorting action again in the rotating sorting cylinder 0η.

The finished rice that has fallen into the finished rice flow down guide plate (a) and the finishing rice gutter αη is conveyed by the finishing rice spiral M to the finishing rice flow down tube Qυ, passes through the finishing rice flow grain board (Incorporated), and is transferred to the finished rice receiving gutter (ha). ), it is sorted by a sorting wind and taken out of the machine by a finished rice lifting machine. In addition, the sorted rice sent to the discharge side end of the rotary sorting cylinder (11) flows into the paddy lifting cylinder (A), and is pumped upward by the rice lifting cylinder (C).
The paddy is reduced to the shedding section (1) via the paddy reducing tank (e), and is again subjected to the action of shedding at the shedding section (1).
