摘要:
An agricultural device (10) for controlled unloading of grain including an unloader conveyor (34) including an enclosed housing having an inlet end (32) including an opening for receiving grain, and an opposite outlet end including a discharge opening through which the grain can be discharged. An unloader conveyor element (36, 40) extends through the housing between the ends and operable for conveying the grain through the housing from the inlet end (32) and discharging the grain through the discharge opening. The unloader conveyor element (36, 40) includes a substantially vertical unloader conveyor segment (36) connected to a substantially horizontal unloader conveyor segment (40). An unloader drive (44) selectably operates a portion of the conveyor element (36, 40) associated with the substantially vertical unloader conveyor segment (36) in a disengaged mode in response to a sensed cumulative loading condition of the substantially vertical unloader conveyor segment (36) and the substantially horizontal unloader conveyor segment (40) exceeding a predetermined value.
摘要:
The control of an apparatus (18) within a grain holding device (14) for feeding grain to an unloader conveyor (12) operable for conveying the grain from the holding device, includes sensing a predetermined condition or conditions representative of capacity of the unloader conveyor (12) for receiving grain, and adaptively controlling the apparatus (18) for feeding grain to the unloader conveyor (12) in advantageous varying manners responsive to the conditions, including to delay initiation of feeding until the receiving capacity is increased, and to match the grain feed to the capacity. The automatic control can be overridden, to allow user control of unloader speed, and can be configured to allow cleanout of the unloader conveyor (12).
