Conventional technology Conventionally, at the bottom of the a-wall that forms a storage chamber for storing grains,
This operating device was equipped with a weight sensor that detected the weight of grains to be staked into the storage chamber, and stopped the grain loading operation based on the detected weight detected by the weight sensor.

Problems to be Solved by the Invention A weight sensor detects the weight of grains to be tensioned and stored in the storage chamber, and the grain tensioning operation is stopped based on this detected weight. The grain density varies; for example, rice grains generally have 540 kg, barley grains have 620 kg,
The weight of wheat grains is 680 kg, so if the same weight of paddy grains as wheat grains is strung into the storage chamber during paddy grain tensioning, the amount of grains to be strung will be too large. In some cases, the grain circulation system is clogged with grains, making it impossible to dry the grains, and causing frequent damage to the grains.
