Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention is applied to a cereal drying preparation facility that receives cereals from respective producers and ships them through processes such as drying, selection, and storage. In addition, the present invention relates to an improvement of a grain voluntary inspection device that collects a part of the received grain as a voluntary verification sample and voluntarily verifies the sample.

(Prior Art) Conventionally, as this type of apparatus, one described in Japanese Patent Application Laid-Open No. 1-1171655 is known.

In this device, when the sample paddy is supplied to the distributor, it is divided into approximately two parts here, one sample paddy is accommodated in a sample holding container, and the other sample paddy is supplied through a supply hopper into a paddy scale. It is configured to be weighed by being put into the hopper.

Furthermore, this device supplies the paddy whose weight has been measured to the huller by a slougher, and after the hulling, sorts it into unregulated rice and unripe rice with a grain sorter, and separates the sorted unpolished rice and immature rice into brown rice, respectively. It is configured to measure with a measuring instrument.

(Problems to be Solved by the Invention) As described above, the conventional apparatus has a distributor, and this distributor has only a function of substantially dividing the supplied sample paddy into two. On the other hand, the amount of the sample paddy supplied to the distributor is not always constant and fluctuates. Therefore, the amount of the sample paddy distributed by the distributor and supplied to the paddy meter varies, and there is a disadvantage that the voluntary verification accuracy is low.

The present invention has been made in view of such a point, and an object of the present invention is to solve the above-mentioned drawbacks.

(Means for Solving the Problems) In order to achieve the above object, the present invention is configured as follows.

That is, the present invention is a dispensing scale for distributing the sample paddy for voluntary verification to a sample paddy for hulling of a predetermined weight, and the remaining paddy sample paddy, and the storage paddy is expanded and passed through between the rolls. The hulling sample hulling is a hulling roll that shrinks between rolls and escapes, and the storage hulling that passes through the hulling roll to the hulling standby unit,
In addition, a down-flow direction switch for guiding the removed sample grains to a grain sorter, a sample measuring instrument for measuring the unregulated brown rice and immature grains selected by the grain sorter, respectively, And a sample unloader that sequentially unloads the sample unpacked to the sample packaging machine.

(Operation) In the present invention configured as described above, when the dried sample paddy for voluntary verification is supplied to the dispensing and measuring instrument, the paddy is distributed to a predetermined weight of the hulling sample and the remaining storage sample paddy.

At this time, since the hulling roll is in the open state, the sample paddy for storage passes through the hulling roll and is guided to the hulling standby unit by the downflow direction switch to be in a standby state.

After that, when the hulling sample is supplied to the hulling roll, the hulling roll is in a closed state. At this time, the hulling sample that has been deprocessed here flows down. It is led to a grain sorter by a switch.
