GRAIN PARAMETERS CONTROL DEVICE Russian patent published in 2001 - IPC

FIELD: agriculture. SUBSTANCE: invention is designed for measuring temperature and humidity of loose materials using electric devices, particularly, checking parameters of grain in grain driers, active ventilation hoppers, etc. Proposed device has drying chamber in K horizontal sections of which MxK hollow shafts are installed, being secured on chamber walls by means of bearing units with split bearings and connected through transfer mechanism and electromagnetic clutch with drive of discharge device. Each of N+I shafts is divided by partition into N sections in each of which one temperature sensor and grain moisture sensor are installed and connected through switching unit to metering device. Electromagnetic clutch, in its turn, is connected to time relay. EFFECT: enlarged operating capabilities and improved accuracy of grain parameters checking. 3 cl, 1 dwg
