Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a grain rotary sorting device for separating and sorting removed processed rice into paddy and brown rice.

[Prior art]

The mixed rice that is supplied as appropriate is scooped up through the pot hole formed on the inner circumferential surface of the rotating sorting tube, and the brown rice that is lifted high is collected into the finishing rice gutter, and the brown rice is removed from the pot hole at a lower level and then exits from the discharge side of the sorting tube. The pot hole of the rotary sorting device that separates and sorts the paddy that is discharged is formed in a sea pattern extending from the supply side to the discharge side.

[Problems to be Solved by the Invention] On the grain supply side of the rotary sorting cylinder, there is a large amount of mixed rice and a high proportion of grains are inserted into the pot holes, so paddy is likely to be scattered and mixed into the finishing rice trough. On the other hand, the mixed rice layer gradually becomes thinner as it reaches the discharge side, and the paddy ratio increases significantly on this discharge side, so the paddy fits into the pot hole, and in the same way, the paddy scatters and mixes in the finishing rice trough, and the pot hole shape If they were uniformly formed as described above, the sorting accuracy would be degraded.

[Means to solve the problem]

In order to solve the above-mentioned drawbacks, this invention has a large number of pot holes on the inner circumferential surface, and scoops up mixed rice while rotating on a horizontal axis, and collects the brown rice into the finished rice trough α-uniform. A rotary sorting cylinder αO is provided to separate and sort the toughness to be discharged to the outside, and the above-mentioned pot hole has a small diameter or shallow hole α on the grain supply side (a) and the grain discharge side (b) of the rotary sorting cylinder 00. The structure of the grain rotary sorting device is such that standard hole α2 is formed.〇 [Operation and effects of the invention] The mixed rice supplied to the rotary sorting cylinder is scooped out by the pot hole, and long grain paddy is placed in a low position. However, short-grained brown rice is lifted up to a high position and collected in the finishing rice trough. Since the potholes on the supply side are configured with small diameters or ronin, the amount of mixed rice is large, and the percentage of paddy stuck in the potholes is high, and both paddy and brown rice tend to fall out at low positions, reducing the recovery rate to the finished rice trough. This promotes the flow transition from the lowering type to the discharge side, and the mixed rice layer on the supply side collapses more quickly. In the middle part, the pot hole is formed into a standard hole, which increases the brown rice recovery rate. Furthermore, on the discharge side, as the amount of brown rice has decreased significantly, the proportion of paddy that gets stuck in the pot holes increases, but since the pot holes are small in diameter or are considered to be ronin, they tend to fall off at low positions, making it difficult to transfer to the finishing rice trough. Reduce.

In this way, the pot holes on the supply side and discharge side of the rotary sorting cylinder, which have a high proportion of paddy fitting into the pot holes, have small diameters or are sloppy, so that there is little contamination of rice into the finished rice trough, and the sorting accuracy can be improved.

〔Example〕

An embodiment of this invention will be described based on the drawings.

(1) is a shedding part, which includes a paddy supply funnel (2) and a pair of shedding rolls (3) (3). A dust exhaust air passage (4) is formed below the removing part (1), and the rice husks mixed in the removed rice are sucked out by a suction fan (5), and the rice husks are removed through a dust removal pipe (6). The structure is such that the air is discharged to the outside, and the stubs and the like are accumulated downward from the middle of the air path (4).

The washed out mixed rice of paddy and brown rice falls into the lower receiving trough (7). (8) is a yangkofu that is connected to this.

Reference numeral (9) denotes a sorting machine frame, inside which a rotary sorting cylinder part with a number of potholes on the inner peripheral surface is provided so as to be rotatable around a horizontal axis. The pot holes are on the mixed rice supply side (a) and the discharge side (b).
The ones in the small diameter to Ronin α1)Ql)... are formed, and the ones in the middle are formed as standard holes a2(to)...

The machine frame (9) is provided with a mixed rice transfer gutter α4 with an open top surface to be located inside the rotary sorting cylinder 00, and the end opening of the grain lifting machine (8) can be seen from the starting end side of the gutter α4. Then, the feed side (A) (machine frame (9)) of the rotating sorting cylinder (10) is
The structure is such that the mixed rice is transferred to the rear side of the

(g) is a finished rice gutter installed parallel to the mixed rice transfer gutter a3, which is equipped with a transfer spiral αG and is connected with a control valve pupil whose angle can be adjusted arbitrarily. The mixed rice is scooped into the pothole of the rotary sorting tube QG, and the brown rice that is lifted high and falls is transferred to the finishing rice gutter αG over the control valve αη, where it falls off at a lower position and is sent to the mixed rice transfer gutter α3 and the lower part. The structure is such that the paddy is separated from the paddy that is returned to the mixed rice layer.

The discharge side of the finishing rice gutter αυ communicates with the brown rice flow down cylinder. A grain flow plate α9t is provided below this flow tube (toward) to guide the brown rice into the brown rice gutter (1). Qll is a grain frying machine.

On the discharge side of the rotary sorting cylinder α1, an annular body @ (7
The inner peripheral surface of this annular body is provided with grain lifting blades (to) (c) at predetermined intervals to remove uncollected grains that have reached the discharge side of the rotary sorting tube (10). It is configured to scoop up paddy including brown rice.

(C) is a reducing hole opened in the front wall of the sorting machine frame (9), and E7 corresponds to the width of this reducing hole.
A slanted return gutter (c) is provided to receive the paddy etc. that is scooped out.

The rear wall of the supply funnel (2) in the detached part (1) is joined to the front surface of the sorter frame (9), and the flow from the inclined return gutter (toward) is returned to the supply funnel (2). This is the configuration that will be used.

(To) The roll that comes off (31 (31...), the suction fan (
5) This is a motor that drives each part of the one-rotation sorting system, the grain transfer part, etc.

The action of the upper side will be explained.

When the motor is started and paddy is supplied to the paddy supply funnel (2), the rice is removed from the roll (3) (s+) and the rice is removed while passing through the processing area. When rice is harvested, it is wind-selected to separate and remove the rice husks and husks.The mixed rice of paddy and brown rice is
After passing through the receiving trough (7) and the grain lifting machine (8), the mixed rice is supplied to the mixed rice transfer trough αJ of the rotary sorting section. Furthermore, it is sequentially transferred by the feeding action of the transfer spiral α→ to the supply (11) of the rotary sorting cylinder (10).
This brings us to 11 (a).

The rotary sorting cylinder αO rotates in a fixed direction and scoops up the mixed rice in the pot hole. The brown rice rises to a high position, passes the control valve αη, and falls into the finishing rice trough αυ. In addition, the paddy also tries to be scooped up in the pot hole, but since it is a long grain and has a high center of gravity, it falls off at a lower position than the brown rice falling position and flows into the rotating sorting tube aO, or The mixed rice falls into the transfer gutter αJ and is returned to the supply side of the rotary sorting cylinder αO again.

By the way, on the supply side (a), the pot hole is small diameter or ronin αυ.
αD... Both brown rice and paddy fall at a relatively low position, and long-grained paddy, in particular, is hardly collected into the finishing rice trough αQ, and the rotating sorting tube αQ This is to promote the migration of the mixed rice layer, which is about to be piled up at the bottom of the tank, to the discharge side. In the middle part, the pot hole is a standard hole (2)
It is possible to scoop up the brown rice that tends to sink to the lower layer of the mixed rice layer that is formed and gradually exhibit a gentle inclination angle and collect it in the finishing rice trough αG.

Furthermore, on the discharge side (0), where the mixed rice layer has become a thin layer and the proportion of brown rice has decreased, the pot hole is formed in a small diameter to Ronin Ql), similar to the supply side, so the proportion of paddy mixed into the pot hole is low. Even if the brown rice is high, it is unlikely to fall off at a relatively low position and be collected in the finishing rice trough 0υ, and the brown rice is collected repeatedly from the supply side to the discharge side in the rotating sorting tube QG to the finishing rice trough Q9. It is possible to perform highly accurate sorting by minimizing the amount of paddy mixed in.

In addition, for brown rice, there is a brown rice flow tube (to), a brown rice gutter (1), and a grain lifting machine■
It is taken out of the machine via D.

At the discharge side (b) end of the rotary sorting cylinder, the toughness and unrecovered brown rice remain, but the fried grain blades on the inner peripheral surface of the annular body @...
It is scooped up by ・ and rises, is received by the inclined reduction gutter @, and flows down to the reduction hole (C) side. The process of wind sorting and rotational sorting is repeated, where it is mixed into the original state and removed again.

Note that the pot holes on the supply side (a) and the discharge side (b) do not necessarily have to have the same shape.
