Description

[Detailed Description of the Invention] Industrial Field of Application The present invention eliminates farmers' dissatisfaction during self-verification work by accurately measuring the finished moisture value of sample grains in a communal drying facility. This invention relates to a device for measuring moisture content of sample grains that can be made easier.

Conventional technology Conventionally, in a communal drying facility, some sample grains of each grain brought in by individuals and consignees were finished and dried to a constant moisture value under the same drying conditions, and the durability of the grains brought in was determined. A sample dryer that accurately allocates the sales proceeds to producers according to the amount of production is known and was described before this application, for example, in Japanese Patent Application Laid-open No. 131181/1981, the contents of which are shown in Figure 3. I will explain using That is, the electrode insertion port 13 is provided at the back end of the drawer-shaped sample case 2 that stores the sample 1 in a stationary state, and corresponds to the housing part 11 of the sample dryer main body 7 into which the sample case 2 is installed. The above-mentioned outlet 13 is located in the position.
An electrode is arranged to be inserted into the sample case 2 through the electrode, and the sample moisture information is obtained from the capacitance value 4 of the electrode.
is a vent hole drilled in the bottom of the drawer-shaped sample case 2; 6 is a hot air; 8 is a heater; 9 is a fan; 10 is a hot air generator; 12 is fixed to the side of the sample dryer main body 7. The electrode substrate 15 is made of an elastic material, and with such a structure, when the sample case 2 containing the sample 1 is inserted into the accommodating part 11 of the sample dryer main body 7, the electrodes are inserted. The electrode substrate 12 protrudes from the opening 13 into the sample case 2, and accordingly pushes a part of the sample 1 upward to reduce the apparent density of the sample 1, reducing the apparent density of the sample 1 between the electrodes. The aim is to reduce the influence of density and improve moisture measurement accuracy.

Problems to be Solved by the Invention By the way, the moisture measuring means of sample grains in the conventional sample dryer of this kind measures a large number of sample grains housed in a sample case, so the obtained measurement There are many variations in moisture values, and as a result, there inevitably arises a difference between the finished moisture content value of the sample grain and the measured moisture value, and as a result, it is not possible to finish and dry all of the sample grains to the desired moisture content value. Problems such as problems such as over-drying or over-drying resulted in complaints about grading and dissatisfied farmers.

Means for Solving the Problems The present invention quickly solves the above problems and eliminates variations in the measured moisture values of sample grains.
The apparatus for measuring the moisture content of sample grains according to the present invention, which is designed to obtain more accurate moisture measurement values, will be described below with reference to FIGS. 1 and 2, which correspond to embodiments.

That is, a plurality of sample boxes 10 each containing an appropriate amount of sample grain A are arranged side by side.

A collection device 109 comprising 10 is provided. The sampling device 109 can be moved in the front-back and left-right directions with respect to the plurality of sample boxes 106 by means of a back-and-forth moving device 112 and a left-right moving device 113.

A conveying device 115 is provided on one side of the lower part of the collecting device 109 to supply the sample grain A collected by the collecting hand 110 one by one to the crushing type moisture detecting device 114.

Function Now, at the communal drying facility, a portion of each grain brought in by individuals and consignees is taken out and used as sample grain A. A plurality of sample grains A are housed in a stationary state in sample boxes 106 arranged side by side so that they can be taken in and taken out freely. Therefore, dry hot air is blown so as to circulate inside the plurality of sample boxes 106 to dry the sample grain A in each sample box 106 under the same conditions.

By the way, as a result of the drying process described above, the sample grain A has a predetermined finished moisture value (for example, 14.5
