Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a rotary sorting device that is integrated with a huller and separates mixed rice into paddy and brown rice.

[Prior art]

The finishing valve of the brown rice transfer gutter located inside the rotary sorting tube is composed of a single plate extending from the grain supply side to the discharge side of the sorting tube, and prevents paddy from being mixed into the recovered brown rice. Adjust the rotation while checking the ratio, etc.

In addition, the mixed rice layer in the rotary sorting cylinder is detected, the amount of grain supplied to the husking section is adjusted, and at the same time, the finishing valve is configured to rotate to adjust, thereby facilitating operation.

[Problems to be solved by this invention] However, in the above embodiment, when the amount of mixed rice in the rotary sorting cylinder is small and thin,
Since the entire finishing valve moves in the direction of reducing brown rice intake, efficiency decreases on the supply side where there is a relatively large amount of brown rice.
It is reduced to the prolapsed area and causes so-called skin shearing.

[Means to solve the problem]

This invention aims to solve the above-mentioned drawbacks and has taken the following technical measures. That is, in a rotary sorting device that collects brown rice into the brown rice transfer gutter 14 while scooping up the mixed rice supplied to the rotary sorting cylinder 11 through the pot holes 10, 10, . Finishing valves 16, 17
is constituted by a plurality of divided bodies extending from the grain supply side to the discharge side of the rotary sorting tube 11 so as to be independently rotationally adjustable, and is provided with a detection means for detecting the mixed rice layer in the one-rotation sorting tube 11. , a rotary sorter configured to change and adjust the amount of paddy supplied to the husking section based on the detection result, and to adjust the rotation of the finishing valve 17 on the grain discharge side of the sorting cylinder among the split finishing valves. The configuration of the device.

[Operation and effect of the invention]

The mixed rice fed into the rotary sorting cylinder is scooped up by a pot hole, and the brown rice is collected into the brown rice transfer gutter after passing through the dividing finishing valve.

When the mixed rice layer becomes thinner, the detection means detects this.

Of the split finishing valves, the finishing valve on the grain discharge side is rotated in a direction to reduce grain collection, and when the mixed rice layer becomes thicker, the finishing valve on the discharge side is rotated in the opposite direction. On the discharge side, where there is less mixed rice, the proportion of paddy is high, and as the layer becomes thinner, this tendency becomes more pronounced and the paddy tends to be scooped up higher, but this can be prevented by independently rotating the discharge side finishing valve as described above. Can correspond to

On the other hand, on the supply side, even if there is a slight change in the amount of mixed rice, the percentage of rice stuck in the pot hole is high, and this brown rice should be recovered as much as possible, but the finishing valve on the supply side does not care about changes in the mixed rice layer. It is independent and can work while maintaining the proper position.

In this way, the discharge-side finishing valve rotates in accordance with the detection result of the mixed rice layer, improving sorting accuracy and facilitating operation.

〔Example〕

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

1 is a husking section, which includes a paddy supply funnel 2 and a pair of husking rolls 3, 3.
A dust exhaust air passage 4 is formed below the 6-shuring section 1, which sucks out the rice husks mixed in the removed rice, and collects the dust from the middle of the air passage 4 downward.

The washed out mixed rice of paddy and brown rice falls into the receiving trough 7 below. 8 is a grain lifting machine connected to this.

9 is a sorting machine frame, inside of which there are many pot holes 10,
A rotary sorting tube 11 having 10... is provided rotatably around a horizontal axis. In addition, a mixed rice transfer gutter 12 is installed in this machine frame 9 with an open top surface so as to be located in the rotary sorting cylinder 11, and the terminal end opening of the grain lifting machine 8 can be seen from the starting end side of the gutter 12. The supply side (
The configuration is such that mixed rice is supplied and transferred to the rear side of the machine frame 9.

Reference numeral 14 denotes a brown rice transfer gutter installed parallel to the mixed rice transfer gutter 12, which is equipped with a transfer spiral 15 and is connected with finishing valves 16 and 17 whose angle can be adjusted arbitrarily.

The above-mentioned finishing valve is divided in the longitudinal direction from the supply side to the discharge side of the rotary sorting cylinder 11 (in the illustrated example, it is divided into two parts), and is divided into a wide finishing valve 16 on the supply side, and a paddy return mechanism section, which will be described later, in the middle. The discharge side finishing valve 17 has a cutout portion formed therein so as not to interfere with the discharge side finishing valve 17. Reference numeral 18 denotes a shaft that supports both finishing valves 16 and 17. The finishing valve 16 on the supply side is constructed integrally with this shaft 18, and the finishing valve 17 on the discharge side is loosely fitted so that it can rotate freely.

The mixed rice is scooped out by the pot holes 10, 10, etc. of the rotary sorting tube 11 and separated into paddy and brown rice, of which the brown rice is transferred to the transfer gutter 14 over the finishing valves 16 and 17 mentioned above. This is a configuration that is transported by the user.

The discharge side of the brown rice transfer gutter 14 communicates with the brown rice flow down tube 19. A grain flow plate 2o is visible below this flow tube 19 to guide the brown rice into the brown rice gutter 21. 22 is a grain frying machine.

On the discharge side of the rotary sorting cylinder 11, an annular body 23 is arranged in series to rotate integrally, and on the inner peripheral surface of this annular body 23, grain frying blades 24, 24, etc. are provided at predetermined intervals. , the paddy mixed with unrecovered brown rice that has reached the discharge side of the rotary sorting tube 11 is scooped up.

Reference numeral 25 denotes a reducing hole opened in the front side of the sorting machine frame 9. Corresponding to the reducing hole 251, a slanted reducing gutter 26 is provided to receive the paddy etc. scooped out by the grain lifting blades 24, 24... .

The rear wall of the supply funnel 2 of the shredding section 1 is connected to the front of the first sorter frame 9, so that the paddy etc. flowing down from the inclined return gutter 26 is directly returned to the second section of the supply funnel.

Reference numeral 27 denotes a layer thickness detector that hangs down to rotate as the layer thickness changes in the mixed rice supplied to the rotary sorting tube, and is connected to the second part of the paddy supply funnel via a support shaft 28, a swing plate 29, a rod 30, etc. The provided supply valve 31 is opened and closed in conjunction with each other.

When the layer is thick, the swing plate 29 is oscillated around the axis 32 to reduce the supply amount, and when the layer is thin, the swing plate 29 is oscillated to increase the supply amount.

An arm 32a is provided on the support shaft 28 of the layer thickness detector 27, and a link 32b is connected between the arm 32a and the discharge side finishing valve 17, so that only the discharge side finishing valve 17 is interlocked depending on the layer thickness change. Configure as much as possible. When the layer is thick, the finishing valve 17 is rotated downward, and when the layer is thin, it is rotated upward.

Reference numeral 33 denotes an efficiency lever that allows the swing plate 29 to swing around the axis 34, and independently of the layer thickness detector 27, the supply amount can be arbitrarily changed.

Reference numeral 35 denotes an adjustment lever, which is connected to the shaft 18 of the finishing valve 16, 17, and can adjust the angle of the finishing valve 16 on the supply side.

36 is the deflated roll 3,3. This is a motor that drives the suction fan 55 rotations, the sorting section, the grain transfer section, etc.

The action of the upper side will be explained.

When the motor 36 is started and paddy is supplied to the paddy supply funnel 2,
Depending on the supply valve 31, the paddy falls between the dehulling rolls 3.3. The paddy is hulled, and the fallen rice is wind-selected when it is sent down the WE through the dust exhaust air passage 4, and the chaff and peaches are separated. The mixed rice of paddy and brown rice is supplied to the mixed rice transfer gutter 12 of the rotary sorting section through the receiving gutter 7 and the grain lifting machine 8. The material is sequentially transferred by the action of the transfer spiral 13 and reaches the supply side of the rotary sorting cylinder 11.

The rotary sorting cylinder 11 rotates in a fixed direction, and the pot hole is 10° 10°.
Scoop up the mixed rice with .... Brown rice is in this pot hole 10.1o.
... and rises to a high position, passes over the finishing valve 16 or 17, and falls into the brown rice transfer gutter 14. or.

Similarly, the paddy tries to be scooped up through the pot holes 10, 10..., but since it is a long grain and has a high center of gravity, it falls out of the pot holes 10, 10... at a low position and is rotated. The rice flows down into the sorting tube 11 or falls into the mixed rice transfer gutter 12 and is returned to the supply side of the rotating sorting tube 11 again. This sorting action is repeated from the supply side to the discharge side of the rotary sorting tube 11 to separate the paddy and brown rice. The brown rice is collected outside the machine via a brown rice flow tube.

On the discharge side of the rotary sorting cylinder 11, paddy and unrecovered brown rice remain, but they are scooped up by the grain lifting blades 22, 22, etc. on the inner peripheral surface of the annular body 21, rise, and are received by the inclined return gutter 24. Then, it flows down to the reduction hole 23 side. The reduced paddy that passes through the reduction hole 23 is mixed into the original rice and undergoes the dehulling, wind sorting, and rotational sorting operations again.Of the six finishing valves 16 and 17, the finishing valve 16 on the supply side is controlled by the adjusting lever 35. Since the angle can be set to , the discharge side finishing valve 17 is interlocked with the layer thickness detector 27. When the amount of mixed rice in the rotary sorting tube 11 increases and becomes a thick layer, the detection body 27 rotates in a direction that moves away from the inner periphery of the sorting tube 11.
Discharge side finishing valve 17 via arm 32a and link 32b
rotates downward.

This also captures particles falling slightly on the lower side, increasing efficiency.

Conversely, when the layer becomes thinner, the discharge side finishing valve 17 rotates upward. When the layer becomes this thin, the proportion of paddy on the discharge side becomes extremely high, and the scooping action in the pot holes 10, 10, etc. continues and there is a tendency to raise the paddy high, but this automatically occurs on the discharge side. By rotating the finishing valve 17, it is possible to reduce the amount of paddy mixed into the brown rice transfer gutter 14.

The setting of the finishing valve 16 on the supply side is adjusted again using the adjustment lever 35 while monitoring the amount of paddy mixed in the recovered brown rice. On this supply side, even if the mixed rice layer changes slightly, a large amount of brown rice is being sent in sequentially, so
, 10... is high, and there is no problem even if the supply-side finishing valve 16 is used almost in a fixed state.In fact, it is better to separate it from the layer thickness detector 27 so as not to reduce the efficiency when the layer is thin. Therefore, it is advantageous.

In this embodiment, the finishing valve is divided into two parts, but it may be divided into two or more parts.Also, if the set length of the link 32a is configured to be freely changeable, fine adjustments can be made when used for different products, and the sorting accuracy can be improved. improve.
