A bulk material dispensing system including a dispensing apparatus suspended from a fixed surface that is configured to receive bulk material from a tank. A metering device feeds the bulk material from the tank to the dispensing apparatus, and a weigh scale is located between the dispensing apparatus and the fixed surface. A controller is in communication with each of the weigh scale and the metering device such that, based on a signal received from the weigh scale that is indicative of the amount of the bulk material that has been fed to the dispensing apparatus by the metering device, the controller controls a rate at which the metering device feeds the bulk material to the dispensing apparatus to ensure that an accurate amount of the bulk material is received by the dispensing apparatus.

The present invention relates to the use of a storage and transfer device to unload granular material from a bottom exit of a tractor trailer bed into a surge hopper, through a transfer device and into a high velocity air stream used to convey the material into a designated silo. Certain embodiments mount the components of the storage and transfer device on a trailer, wherein the transfer device includes a surge hopper, a transfer device, a blower, and a transfer pipe.

A dispensing apparatus for dispensing articles includes a housing and a drive system. The housing defines a hopper chamber to hold the articles, a dispensing outlet, and a dispensing path between the hopper chamber and the dispensing outlet. The drive system includes a belt and a belt actuator operable to drive the belt. The dispensing apparatus is configured such that articles disposed in the hopper chamber are directed onto the belt and the belt, when driven by the belt actuator, conveys the articles received from the hopper chamber in a dispensing direction along the dispensing path toward the dispensing outlet to be dispensed.

Provided is a containing system which includes a first frame structure, a plurality of first discharge units in the first frame structure, extending in a first direction, and fixedly coupled to the first frame structure in a second direction perpendicular to the first direction, a second frame structure detachably coupled to the first frame structure in the first direction, a first containing unit fixedly supported on the second frame structure and spaced apart from the first frame structure, a second containing unit connected to the first containing unit and spaced apart from the first frame structure, a plurality of second discharge units connected to the second containing unit, aligned with the first discharge units in the first direction, and spaced apart from the first discharge units, and a pressure control unit connected to the first containing unit and controlling a first air pressure in the first containing unit to counterbalance a second air pressure outside the first containing unit.
