摘要： An improved tension control apparatus for use in an aero-mechanical conveyor for moving bulk materials includes spaced-apart inflow and outflow conveyor tubes interconnecting the upper and lower housings of the conveyor. A bracket cooperates with the conveyor tubes. A guide sleeve is carried by the bracket for receiving a push rod. The push rod extends along the length of the conveyor tubes from the guide sleeve to the upper housing and includes an upper end engaging the head pulley assembly and a lower end extending through the guide sleeve. A tensioning assembly engages the push rod and is carried by the bracket for urging the push rod against the head pulley assembly, thereby urging the head pulley assembly away from the tail pulley assembly and maintaining tension in the rope assembly. Two dust cap seals interconnect the conveyor tubes with the upper housing to reduce particulate emissions.

摘要： A bag spout retainer apparatus for a bulk bag discharger is the disclosure of the type wherein a frame suspends a bulk bag with a side-secured discharge spout, and the spout is held in a closed position against the bag. A bag-engaging member is mounted on the frame in a position laterally-displaced from a lower end of the bag above the discharge spout. A reciprocating driver is attached to the bag-engaging member and is adapted for moving the bag-engaging member between a retracted position out of engagement with the lower end of the bag and an extended bag engaging position for engaging and holding the bag spout in a closed position against the side of the bag during release of the spout against the side of the bag.

摘要： A tensioning assembly for use in an aero-mechanical conveyor for moving bulk materials. The conveyor includes upper and lower housings having head and tail pulley assemblies mounted therein. The tensioning assembly includes first and second extendable tubes that define sections of inflow and outflow conveyor tubes that interconnect the upper and lower housings. An endless rope assembly is disposed within the conveyor tubes and around the head and tail pulleys. An adjustable actuator is positioned in cooperative engagement with the first and second extendable tubes. When the actuator is in a first position, the extendable tubes have a first length and when the actuator is in a second position, the extendable tubes have a second length. The actuator is configured to move between the first position and the second position in response to changes in tension within the endless rope assembly as indicated by a signal from a tension measuring device.

摘要： An improved tension control apparatus for use in an aero-mechanical conveyor for moving bulk materials, the conveyor including upper and lower housings, head and tail pulley assemblies mounted on respective shafts positioned within the upper and lower housings, respectively, spaced-apart inflow and outflow conveyor tubes interconnecting the upper and lower housings, and an endless rope assembly disposed within the conveyor tubes and around the head and tail pulleys. The improvement includes a bracket cooperating with the inflow and outflow conveyor tubes. A guide sleeve is carried by the bracket for receiving a push rod. The push rod extends along the length of the conveyor tubes from the guide sleeve to the upper housing and includes an upper end engaging the head pulley assembly and a lower end extending through the guide sleeve. A tensioning assembly engages the lower end of the push rod and is carried by the bracket for urging the push rod against the head pulley assembly, thereby urging the head pulley assembly away from the tail pulley assembly and maintaining the rope assembly in a tensioned condition.
