In addition, the present invention relates to a sample grain sampling device for moisture measurement in a test dryer capable of accurately sampling a part of a dried sample grain and automatically supplying it to a moisture meter.

“Conventional technology” Conventionally, in a joint drying facility, a portion of each grain brought in by an individual or by a shipper was dried to a certain moisture value under the same drying conditions and dried, and the grain brought in was carried. A sample grain dryer capable of allocating the producer selling price according to the minutes is known and described in, for example, Japanese Patent Application Laid-Open No. 61-252476 prior to the filing of the present application. A plurality of sample boxes formed in the sample grain storage chamber in which the dry air obtained by the dedicated hot air generator can freely flow are fitted into the dryer body so that they can be inserted and removed, and in the rear of each of the sample boxes, When the sample box is inserted into the main body of the dryer, a moisture sensor is provided which is inserted into the sample grain storage chamber through the insertion portion provided on the rear wall of the sample box.
The insertion part is closed by a pair of leak preventers attached to the sample box so that the free ends thereof overlap each other.

[Problems to be solved by the invention] By the way, in the conventional sample grain dryer of this kind, in order to measure whether or not the sample grain contained in the sample box has been dried to a predetermined moisture value by the circulating drying air. Since the same number of moisture sensors as in the sample box were provided, the whole structure was complicated, and the sample grain dryer was expensive, and the moisture measurement operation was troublesome. .

The present invention has been made in view of the above problems of the conventional technique, and the purpose thereof is to direct a large number of sample containers containing dried sample grains to one side along a moving passage. When the sample container is moved to the lifting device along the moving passage so that it can be moved intermittently, a part of the sample grain in the sample container is sampled by the lifting device to measure the water content. By providing automatic feed to the sample dryer, even if there are many sample containers, it is possible to easily measure the moisture continuously with one pumping device and moisture measuring device. Is what you are trying to do.

[Means for Solving the Problem] In order to achieve the above-mentioned object, the sample grain sampling device for moisture measurement in the test dryer according to the present invention has a large number of sample containers containing dried sample grains along a moving path. It is provided so that it can be moved intermittently toward one side, and a lifting device with a bucket rotatably suspended is arranged above the moving path of the sample container, and a supply hopper is provided on the upper part at the side of the lifting device. , A moisture measuring device provided with a reduction gutter with a drop port looking into the sample container at the bottom, and a guide hopper movably disposed between the discharge position of the above-mentioned lifting device and the supply hopper, and A slow-speed rotation switch is provided on the lower side of the lowering process of the lifting device, and a high-speed rotation switch and a slow-speed rotation switch are provided on the lower and higher positions of the raising process side.

Further, it is preferable that the bucket used in the device is formed by the left and right side plates and the back plate so as to have a U-shaped cross section, and the base end side of the back plate is provided with an arcuate bulging scooping storage chamber.

[Operation] Now, one of the sample containers containing the sample grains dried by the test dryer is moved to the lifting device along the moving path and stopped. Then, if the lifting device is started, a single bucket provided in a suspended manner will rotate in the direction of the arrow to properly scoop up and lift part of the sample grain (for example, 10 g) stored in the sample container. After that, some of the sample grains scooped at the upper discharge circulation position are supplied to the moisture measuring device via the guide hopper and the supply hopper, and the moisture value is measured quickly and accurately, and the excess sample is sampled via the reduction gutter. Return to.

By the way, during the lifting operation as described above, when the bucket is turned on, the slow rotation switch provided on the lower side of the descending process is turned on, and the bucket is rotated at a slow speed to accurately scoop the sample grains in the sample container. The bucket is moved to the ascending process while raising, and then the bucket is moved at a high speed immediately after passing through the high-speed rotation switch arranged on the lower side of the ascending process. After passing the bucket, the bucket can rotate slowly and the sample grain scooped up can be slowly discharged to the guide hopper.

Then, after the bucket discharges the sample grain, when it reaches the slow rotation switch at the starting position provided on the descending process side, the bucket stops here and does not operate until the next sample container moves. .

The bucket for scooping the sample grain is formed in a U-shaped cross section by the left and right side plates and the back plate, and is provided with an arcuate bulging scooping storage chamber on the base end side of the back plate. Part of the sample grains stored in the sample container is properly picked up in the arc-shaped swelling and picking-up storage chamber, and then transported and simultaneously the back plate becomes a shout when discharged. The sample grain can be smoothly discharged to the guide hopper.

[Example] An example will be described with reference to the drawings.
