Description

[Detailed Description of the Invention] "Field of Industrial Application" The present invention targets grains such as rice, mainly wheat,
This invention relates to a method for drying sample grains in grain communal drying facilities such as rice centers, country elevators, and dry stores, which are comprised of a receiving section, a drying section, a storage section, a preparation and shipping section, etc.

"Prior Art" Conventionally, as a technique for drying and detecting moisture, there have been techniques shown in Japanese Utility Model Application Publications No. 145493/1983 and No. 155893/1989.

``Problems to be Solved by the Invention'' The above-mentioned conventional technology includes a technique of placing sample grains in a container and drying them for a predetermined period of time, and a technique of installing a plurality of moisture detection mechanisms in the drying system of the veneer to detect moisture content within a predetermined amount. It merely discloses the following techniques for removing the veneer.

In addition, as shown in Japanese Utility Model Application Publication No. 55-31440, a drying technology for the facility itself that simultaneously dries a large amount of grain for a predetermined period of time by bulk drying, and Japanese Patent Application Publication No. 59-3144
As shown in Publication No. 231436, there was an inspection machine in which a worker manually inputs sample grains, but each of the above-mentioned conventional techniques does not involve placing sample grains in a container and circulating them within a drying chamber. Therefore, deterioration in the quality of sample grains due to rapid drying cannot be easily prevented, and the sample grains are automatically transported to the inspection machine when the moisture content of the sample grains in the container falls below a predetermined level. Therefore, there were problems such as it was not easy to automate and save labor in the drying and testing of sample grains.

``Means for Solving the Problems'' However, the present invention provides a grain transport mechanism that separates sample grains, stores them in containers, and circulates them within a drying chamber, and a grain transport mechanism that separates sample grains, stores them in containers, and circulates them within a drying chamber, and A moisture detection mechanism that measures the moisture content, and a grain that automatically transports the sample grains in the container whose moisture content is below a certain level to an inspection machine that separates them into regular grains and waste grains and measures the proportions of these grains. and a discharge mechanism, and is configured to automatically supply the sample grains placed in the storage body, dried to a predetermined moisture content, to the inspection machine according to the classification by the storage body. be.

``Effect'' Therefore, since the sample grains placed in the storage body are circulated within the drying chamber, the time required for drying can be lengthened, and the sample grains can be gradually dried in sections, thereby preventing the sample grains from being rapidly dried. In addition to easily preventing quality deterioration and confusion with sample grains received from other consignees, sample grains in the drying chamber whose moisture content has fallen below a predetermined level are automatically transported to the inspection machine according to the classification using storage bodies. Therefore, each operation of drying and inspecting sample grains can be easily automated and labor-saving, and the commercial value judgment of received grains in a grain communal drying facility can be easily determined.

It is equipped with take-out arms 45 and 46, which are grain discharge mechanisms, which automatically transport the sample paddy No. 8 into regular grains and waste grains to an inspection machine 23 that measures the ratio of these grains, and the grains are placed in a bag body 28. The sample rice is dried to a predetermined moisture content and is automatically supplied to the inspection machine 23 according to classification by bags 28.

The present embodiment is configured as described above and is installed in a rice center, country elevator, dry store, etc. Raw paddy harvested by a combine harvester or the like is input into the receiving and weighing machine 3 individually and by parcel, and is weighed. A sample loader 16 transfers a certain amount of homogenized sample rice from the weighed raw rice in the tank 7 via the fractionator 14 and the metering branch valve 15.
At the same time, the sample paddy from the loader 16 is dried to the set moisture content using the test dryer 18, and the dried sample paddy is fed into the self-inspection machine 23, and the processed brown rice and scrap rice are weighed and their ratios are determined. The operation of each part is controlled by the central controller 11 based on the consignment number, and based on the self-inspection data of the sample paddy that corresponds to the consignment number, the administrative calculator calculates the proportion of browned rice for each individual and consignment. 10.

The operation inside the test dryer 18 will be explained with reference to the float chart in FIG.
Now, when the bag body 28 is being moved by the chain conveyor 33 and reaches the first switch 77 position, and the switch 77 is turned on and the third switch 79 is also turned on, the cylinders 60 and 61 are operated and the chuck arms 43 and 44 are turned on. Moisture sensor 42
The moisture value α at this time is memorized, and then when the chuck arms 43 and 44 are opened to the a position and the bag body 28 is brought between the arms 43 and 44, the second switch 78 is turned on. The chuck arms 43 and 44 close again to position b, and the bag body 28
Detect the moisture content β of the sample paddy. When the difference (β-α) is below a certain level and the bag body 28 reaches the fourth switch 80 position and the switch 80 is turned on, the cylinder 72 operates to close the take-out arms 45 and 46 and remove the creep. 32 is released from holding the bag body 28, and the bag body is discharged from the outlet port 21 to the outside of the machine.

In the above embodiment, the chuck arms 43, 44
Although the chuck arms 43 and 44 are provided so as to be perpendicular to the moving direction of the bag body 28, they may be provided substantially parallel to each other so that the bag body 28 moves through the center of the gap between the chuck arms 43 and 44.

"Effects of the Invention" As is clear from the above embodiments, the present invention provides a grain transport mechanism 33 that separates sample grains, stores them in the storage body 28, and circulates them within the drying chamber 18a.
