NON-CONTACT GRAIN FLOW MEASUREMENT SYSTEM

摘要

The present invention relates to a noncontact grain flow measuring system, capable of accurately confirming a yield of grain without a time delay, occurring when measuring the yield of the grain during storage, by sensing the flow of the grain, falling after being threshed in a combine, without contact. The system includes: a noncontact sensing part (10) placed in a selective fluid body part between a selecting part and a threshing part, and measuring and transmitting a voltage according to the flow of the threshed and falling grain; a sensing information receiving part (20) receiving the sensed voltage value, transmitted from the noncontact sensing part (10); a sensing voltage value adjusting part (30) adjusting a voltage value of each sensing part to a correction voltage value by averaging the voltage value of each sensing part, received from the sensing information receiving part (20), by second; and a grain flow calculating part (40) calculating a final voltage value, averaged from the correction voltage value adjusted by the sensing voltage value adjusting part (30), with a grain amount calculation formula according to the type of the grain.
