摘要:
An arrangement in grading and cleaning machines with a screen (15). The screen is associated with at least one sensor (24) in the flow of material passing through the screen for generating electric signals in dependence on material particles leaving the screen as throughput and impinging on the sensor. The sensor is operatively connected to adjusting means (26) through a function circuit (25) for the control of an operational parameter of the screen (15) in dependence on the impingement intensity.
摘要:
An arrangement in a winnower comprising at least one rotational member (10) e.g. a disk or a cylinder, having cells for lifting seeds and other particles from a lower position to a higher position and a chute (14) for receiving the lifted material. The rotatable member is associated with at least one sensor (17) located in the flow of the lifted material supplied to the chute, for generating electric signals in dependence on impingement of material particles leaving the rotatable member and falling down into the chute. The sensor is operatively connected through a function circuit (18) to adjusting means for controlling an operational parameter of the winnower in dependence on the impingement intensity.
摘要:
An arrangement in machines for separating materials having different aerodynamic properties, comprising means for generating an ais current actuating the materials. A sensor is located in the path of particles carried along by the air current, to generate electric signals in dependence on particles impinging the sensor. The sensor is operatively connected to means for controlling the flow rate of the air current in order to obtain an airflow corresponding to a predetermined impingement intensity.
