Device for optical counting small grains chen

摘要

Device for optical counting of small beads, in particular that of a sowing machine, the duration of the seeds, in which the body to be counted, which is equipped with optical sensors and measuring space is arranged in a delivery line may pass through and in this case the light gear between a light emitter and a light detector of the sensors interrupt. In order in a simple manner the sensor or, respectively, the sensor shielding translucent elements to be protected against contaminants, is provided that the sensor a cleaning - and / or purely holding device is associated with.
