| Abstract: | Introduce the operating principle of grain loss sensor with briefness, sum up and point out some general problems of existent arts, put forward corresponding improvement design of the structure. The detector plate member is provided with signal damping means substantially around the periphery thereof ,and anti-vibration mounts are used to mount the detector plate on the combine harvester at the required location. After make and assembly, present a laboratory calibration. |
