PURPOSE:To obtain grains mixed in a given proportion with excellent accuracy by charging grains stored in a weighing and regulating tank into an automatic measuring device and at the same time charging the other variety of grains into the central part of the automatic measuring device. CONSTITUTION:An enriched rice tank 16 is provided with the upside belt converyer 13' and also is fixed in a freely slope regulatable manner to the pneumatic transport pipe 17 leading to the weighing regulation tank 15 through a flow rate regulating damper 18 and then to the casing 19 through a bracket 20. The front end of the pneumatic transport pipe 17 is provided with an air hose 21 and then connected to an air compressor through the electromagnetic valve V1, the pressure regulating valve V2, and the filter F in order. On the other hand, the front end of the pneumatic transport pipe 17 is provided with a discharge pipe 22 which is connected in a branched way to the lower discharge pipe 23 of the weighing regulation tank 15 so as to reach the center of the lower automatic measuring device 25. Thereby, the mixing accuracy of grains can be raised. |
