Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to mixed rice in a rotary sorting device that has multiple stages of sorting tubes for separating and sorting deculled mixed rice into brown rice and paddy. This invention relates to a quantity control device.

[Problems to be solved by the prior art and the invention] If a plurality of sorting tubes are provided independently, and the strained rice is distributed and supplied, the efficiency of the sorting tubes can be improved compared to a single sorting tube. It is advantageous. By the way, when recovering finished rice, the collecting angle of the finishing valve connected to the finishing rice trough can be arbitrarily adjusted to prevent rice from getting mixed in. It is not always possible to ensure a constant distribution supply amount, and the finishing valve angle must be set independently for each, which tends to make the operation complicated.

[Means for Solving the Problems] The present invention has taken the following technical means to solve the above-mentioned drawbacks. That is, a large number of pot holes 17, 17...
- A sorting tube 11 that scoops up mixed rice while rotating around a substantially horizontal axis and collects brown rice into finishing rice troughs 15 and 16.
．． In a rotary sorting device in which a plurality of 12 are installed in parallel, each sorting tube 11, 12 is equipped with a layer thickness sensor 40, which can detect the amount of mixed rice.
41 is arranged so that the amount of mixed rice supplied into the sorting tube 11 can be adjusted by the layer thickness sensor 40 of the standard sorting tube 11, and the layer thickness sensors 41 of the other sorting tubes 12 The mixed rice amount control device in the rotary sorting device is configured to adjust the mixed rice supply amount, inclination angle, or mixed rice transfer means of the sorting cylinder 12 in accordance with the layer thickness sensor 41 of No. 11.

[Operations and Effects of the Invention] The plurality of sorting tubes arranged are divided into a standard sorting tube and other sorting tubes, and a layer thickness sensor installed in the standard sorting tube controls the amount of mixed rice supplied to the sorting section to determine the standard sorting tube. This is to ensure a constant amount of mixed rice in the sorting tube, and the layer thickness sensor installed in the other sorting tubes is compared with the layer thickness sensor of the standard sorting tube. The amount of rice supplied, the angle of inclination, or the mixed rice transfer means are adjusted in conjunction with each other.

Therefore, the standard sorting tube and the other sorting tubes exhibit substantially the same sorting tendency, and for example, it is not necessary to adjust the finishing valve for each sorting tube, thereby simplifying the work.

Each terminal end of the finished rice @ 15 and 16 is directed into the brown rice flow tube 33, and the flowed brown rice passes through the receiving gutter 34, reaches the brown rice gutter 35, and is transferred to the grain lifting machine 37 via the transfer spiral 36. It is configured to be taken out from the grain lifting machine 37 outlet.

On the other hand, the terminal end of each sorting tube 11.12 communicates with the lower receiving trough 38, and the paddy containing some brown rice reaching the terminal end of the sorting tube 11.12 is transferred to the supply funnel 2 through the reduction thrower 39. It is configured to return to .

A layer thickness sensor 40.41 is installed inside the sorting cylinder 11.12.
is provided so that the amount of mixed rice can be detected in contact with the mixed rice layer in each sorting cylinder 11, 12.

Among them, the layer thickness sensor 40 of the reference sorting tube 11 is
The layer thickness sensor 4 is configured to control the opening degree of the supply valve 42 provided in the flow path from the supply funnel 2 to the culm rolls 3, 3.
If the angular displacement of 0 is detected and the amount of mixed rice is large, the amount fed to the culm rolls 3, 3 is reduced, and if the amount is small, an angle detector 43 and an angle detector 43 are installed between the two to increase the amount fed. Supply valve 4
A control motor 44 for two operations is provided.

Further, the layer thickness sensor 41 of the second sorting tube 12 is connected to the reference sorting tube 1.

The action of the upper side will be explained.

The paddy from the supply funnel 2 is dehulled while passing between the culling rolls 3 and 3, and the mixed rice that has been subjected to wind selection is transferred to the mixed rice tank 18.
A distribution valve (not shown) separates the mixed rice into the mixed rice transfer gutter 1
3.14, and is supplied into the reference sorting tube 11 and the second sorting tube 12.

Each sorting cylinder 11, 12 scoops up the mixed rice through the pot holes 17, 17, respectively, while rotating at the same rotation speed, and the brown rice is collected into the finishing rice troughs 15, 16 after passing through the finishing valves 27, 28, Long-grained paddy has a high center of gravity and falls out of the pot hole at a relatively low position and is returned to the mixed rice layer. The above sorting is repeated from the starting end to the ending end of the sorting cylinder 11.12 to separate paddy and brown rice. The brown rice joins in the downstream tube 33 from the end of the finishing rice gutter 15, 16, and flows into the receiving gutter 34. Brown rice gutter 35. The grains are taken out of the machine through a grain lifting machine 37 and the like.

In addition, the paddy (including some brown rice) remaining at the end of the sorting tube 11 and 12 is combined in the receiving pipe 38, and then returned to the supply funnel 2 part in the reduction thrower 39, where it is deculled and wind-sorted again. receive.

The layer thickness sensor 40 of the reference sorting tube 11 is connected to the reference sorting tube 11.
It contacts the surface of the mixed rice layer on the supply side and rotates around a support shaft, and its angular displacement is detected by an angle detector 43. The angular displacement, which is proportional to the amount of mixed rice, is compared with the angle of the appropriate amount of mixed rice set in advance. The supply valve operating motor 44 is controlled to reduce the opening degree of the supply valve.

Similarly, the layer thickness sensor 41 of the second sorting cylinder 12 is angularly displaced according to the amount of mixed rice, and this displacement is detected by the angle detector 47. The output from this angle detector 47 is compared with the output from the angle detector 43 of the reference sorting tube "11", and the angles of the variable resistance plates 46, 46, etc. are changed and controlled based on the comparison output. In other words, if the amount of mixed rice in the standard sorting tube 11 is smaller than the amount of mixed rice in the standard sorting tube 11 based on the comparison between the two sensors 40 and 41, the variable resistance plates 46 and 46 are adjusted so that the amount of mixed rice in the second sorting tube 12 is distributed to be approximately the same amount. The angles of the variable resistance plates 46, 46, etc. are set to increase the resistance to mixed rice transfer, and conversely, when the amount of mixed rice is larger than the amount of mixed rice in the standard sorting cylinder 11, the angles of the variable resistance plates 46, 46, etc. are adjusted to smooth the mixed rice transfer. Set it loosely.

In this way, the sorting state of the reference sorting tube 11 and the second sorting tube 12 are changed.
The sorting conditions are approximately equal, and it is sufficient to adjust the angle of the finishing valves 27 and 28 using a single lever 32.

In this embodiment, the reference sorting tube 11 and the second sorting tube 12 are
Variable resistance plate 46, 46 as a means to align the sorting state with
..., but other transfer means may be controlled, or the distribution valve of the mixed rice tank 22 may be configured to be adjustable to control the amount of mixed rice supplied to the second sorting cylinder 12.
