ACTUATOR FOR OPENING AND CLOSING LID FOR BULK STORAGE BIN

摘要

An actuator opens and closes a lid on a bulk storage container. The actuator may be activated remotely using a remote control. When actuated, the actuator will lift the lid so that it is clear of the structure, and will then rotate the lid in a horizontal plan about a vertical axis until the lid is rotated to uncover the opening. The axis of rotation is located near the perimeter of the opening, so that very little of the lid remains over the opening when in the open position. To close the lid from the open position, the remote control may then in he used to actuate the closing process. The closing process works in reverse of the opening process. Therefore, during closing, the lid will rotate back to its original orientation over the hole and then lower into the closed position.

主权项

1. A device for opening and closing a lid on a bulk storage bin, wherein the lid covers an opening at an upper area of the bin, the device comprising:
an actuator operably mounted to the bin in operable connection to the lid, the actuator being adapted to lift the lid from a closed position to a raised position above the opening, the actuator further adapted to rotate the lid from the raised position about a vertical axis located at a periphery of the opening until the lid is in an open position; the actuator adapted to rotate the lid from the open position back to the raised position and to lower the lid from the raised position to the closed position; and a remote control in communication with the actuator to trigger the actuator to move the lid from the closed position to the open position and from the open position to the closed position.
