Abstract
An ore chute system, comprising: a chute box for collecting material and having a chute opening formed therein for discharging the material therethrough; a chute press gate mounted over the chute opening and moveable between an opened position to allow discharge of the material from the chute box and a closed position to prevent discharge of the material from the chute box; a chute press gate actuator coupled to the chute press gate and controllable to move the chute press gate between the opened position and the closed position; and, a chute press gate counterweight system coupled to the chute press gate and configured to move the chute press gate from the opened position to the closed position upon failure of the chute press gate actuator.

An ore chute system, comprising:
- a chute box for collecting material and having a chute opening formed therein for discharging the material therethrough;
- a chute press gate mounted over the chute opening and moveable between an opened position to allow discharge of the material from the chute box and a closed position to prevent discharge of the material from the chute box;
- a chute press gate actuator coupled to the chute press gate and controllable to move the chute press gate between the opened position and the closed position;
- and,
- a chute press gate counterweight system coupled to the chute press gate and configured to move the chute press gate from the opened position to the closed position upon failure of the chute press gate actuator;
- wherein the chute press gate counterweight system includes a chute press gate linkage assembly coupling the chute press gate to a counterweight assembly;
- and
- wherein the chute press gate linkage assembly includes a chute press gate connecting rod assembly coupled at a forward end to the chute press gate and at a rearward end to a first arm of a lever arm assembly, the lever arm assembly having a second arm coupled to an upper end of a counterweight connecting rod assembly, a lower end of the counterweight connecting rod assembly coupled to a counterweight carriage of the counterweight assembly.
An ore chute system, comprising:
- a chute box for collecting material and having a chute opening formed therein for discharging the material therethrough;
- a chute press gate mounted over the chute opening and moveable between an opened position to allow discharge of the material from the chute box and a closed position to prevent discharge of the material from the chute box;
- a chute press gate actuator coupled to the chute press gate and controllable to move the chute press gate between the opened position and the closed position;
- a chute press gate counterweight system coupled to the chute press gate and configured to move the chute press gate from the opened position to the closed position upon failure of the chute press gate actuator;
- a chute lip mounted below the chute opening and moveable between a lowered position to allow discharge of the material from the chute box and a raised position to prevent discharge of the material from the chute box;
- a chute lip actuator coupled to the chute lip and controllable to move the chute lip between the lowered position and the raised position;
- and,
- a chute lip counterweight system coupled to the chute lip and configured to move the chute lip from the lowered position to the raised position upon failure of the chute lip actuator.
