  • Patent number: 10544614
    Abstract: A mechanism for precisely controlling a slide gate to provide certain and secure location of a sliding gate in a path of flowable dry bulk material, the mechanism including a rack and pinon gear with a shaft with a diameter hole therethrough for receiving a pin therethrough when the sliding gate is in a desired position. The swing arm is configured to inhibit removal of the pin and thereby prevent unwanted movement of the gate from the desired position. The swing arm is configured for selectively prohibiting accidental and/or intentional but unauthorized removal of the pin depending upon types of objects being placed through the open hole in the swing arm and the first fixed arm open hole.

  • Patent number: 9309052
    Abstract: A system and method for causing a differential flow rate to exist in a downspout so as to reduce abrasion of a bottom side of said downspout and to sort dry bulk material flowing therethrough. The present invention reduces the velocity of the mass of the dry bulk material, such as corn, thus preserving grain quality and reducing the exit velocity at the lower end of the spout.

  • Patent number: 9284121
    Abstract: A system and method for changing a flow rate and direction of dry bulk material supplied from an elevated source, via an angled spout to an adjustable spout end having no internal baffles therein and having readily interchangeable wear pads therein which are accessible through an access door.

  • Patent number: 7975824
    Abstract: A system and method for changing a flow direction of dry bulk material which comprises constructing a steel clad ceramic elbow or pipe or planar flip gate and placing the same in a location where a flow direction change is desired and where abrasion will occur. The inside of the pipe has a steel surface, as does the exterior of the pipe. The ceramic material is disposed in the gap between the steel exterior and interior. The interior steel pipe wears away in portions but the remaining non-worn away portion still provides valuable support for the uncovered ceramic portions.

  • Patent number: 6325588
    Abstract: The present invention is directed to the remote operation of an auger attached to a portable unit for storing and transporting particulate matter. A bin having a number of sidewalls which converge downwardly and inwardly to a discharge end secured to a frame. A discharge chute is attached to the bin to receive particulate matter from the bin and transfer the particulate matter from the bin. An unloading auger is secured within the discharge chute and powered by a motor which is secured to the frame. In general operation, a clutch assembly engages the motor to the unloading auger causing the particulate matter to be unloaded. A user may use a transmitter to send a signal to a receiver which increases or decreases the output of the motor and engages or disengages the clutch such that the auger may be started or stopped. The transmitter and receiver may communicate using a radio signal. Additionally, wheels may support the frame and a trailer hitch may be attached.
