摘要： A material handling hopper has an open top box with a chamber for holding bulk material. A bottom conveyor operates to remove material from the chamber. A divider located in the chamber reduces the bridging and packing of material in the chamber. The divider is an inverted V-shaped member secured to end walls of the box. The width of the inverted V-shaped member increases in the direction of movement of the conveyor. The divider is covered with low friction material to facilitate the flow of material around the divider.

摘要： A concrete pipe making machine having a combined vibrating core and counter rotating packerhead assembly is used with a mold to prepack and vibrate concrete within the mold to produce concrete pipe. A controller is programmed in response to packing force of the packerhead assembly to control the discharge of concrete into the mold and the lift speed of the core and packerhead assembly to produce concrete pipe having uniform density through out the length of the pipe.

摘要： A concrete product making machine having a counter rotating packerhead assembly and a concrete supply control operable to maintain a desired amount of concrete in the mold above the packerhead assembly. The counter rotating packerhead assembly has a first packerhead unit rotated in one direction by a motor and a second packerhead unit rotated in an opposite direction by hydraulic motors mounted on the cross head of the machine. The second packerhead unit located above the first packerhead unit has a plurality of rollers and an annular trowel. The trowel has radially adjustable shoes which meter the flow of concrete to the first packerhead unit. A control system responsive to hydraulic fluid pressure supplied to the hydraulic motors controls the operation of a concrete supply conveyor operable to deliver concrete to the chamber above the packerhead assembly. The control system includes a control valve assembly operable to regulate the supply of hydraulic fluid to a hydraulic motor operating the conveyor.

摘要： A method and apparatus for making concrete pipe having substantially uniform density throughout the length of the pipe has a packerhead which is rotated and lifted within a mold, and a conveyor for feeding concrete into the mold. A combined conveyor speed and packerhead lift control operates in response to the amount of power used to rotate the packerhead to slow the speed of the conveyor to a desired speed and change the lift speed of the packerhead when the load on the motor for rotating the packerhead exceeds a selected upper load limit or falls below a selected lower load limit.

摘要： A concrete product making machine having a counter rotating packerhead assembly and a concrete supply control operable to maintain a desired amount of concrete in the mold above the packerhead assembly. The counter rotating packerhead assembly has a lower packerhead unit rotated in one direction by a motor and on upper packerhead unit rotated in an opposite direction by hydraulic motors mounted on the cross head of the machine. The upper packerhead unit located above the lower packerhead unit has a plurality of rollers and an annular trowel. The trowel has radially adjustable shoes which meter the flow of concrete to the lower packerhead unit. A control system responsive to hydraulic fluid pressure supplied to the hydraulic motors controls the operation of a concrete supply conveyor operable to deliver concrete to the chamber above the packerhead assembly. The control system includes a control valve assembly operable to regulate the supply of hydraulic fluid to a hydraulic motor operating the conveyor. The control system includes a control valve assembly operable to regulate the supply of hydraulic fluid to a hydraulic motor operating the conveyor. The control system has a pivoted arm connected to a valving member of the control valve assembly. A cylinder having a piston connected to the arm receives the hydraulic fluid under pressure supplied to the hydraulic motors that drive the second packerhead unit. The cylinder controls the position of the arm and valving member in response to the pressure of the fluid supplied to the hydraulic motors. A biasing spring assembly connected to the arm moves the piston into the cylinder to a retracted position when hydraulic fluid pressure supplied to the piston is reduced thereby allowing the valve assembly to return to the open position to continue the supply of hydraulic fluid under pressure to the conveyor hydraulic motor.
