Abstract
A conveying system for heavy material such as overburden that contains large rocks as well as small rocks and dirt. The system has a feed system using two blades that rotate over an apron to push material onto the conveyor and a transition assembly between conveyors that lessens the impact of large rock as it drops from one conveyor onto the next conveyor.
Claims12
A conveyor system, comprising:
- a frame;
- a conveyor having an inlet end and a discharge end for conveying material received in the vicinity of said inlet end;
- an apron having a planar surface mounted on said frame adjacent said inlet end for receiving material;
- a first pusher blade having an outboard side edge and a pivot mount adjacent a first side of said conveyor adapted to pivot and sweep a first arc over said planar surface towards the vicinity of said inlet end for pushing said received material onto said conveyor at said vicinity of said inlet end;
- a second pusher blade having an outboard side edge and a pivot mount adjacent a second side of said conveyor adapted to pivot and sweep a second arc over said planar surface towards the vicinity of said inlet end for pushing said received material onto said conveyor at said vicinity of said inlet end;
- and
- an arcurate skirt affixed to said outboard edge of each of said pusher blades that extends upward from said planar surface to prevent material being swept from said planar surface from entering behind said pusher blades.

A conveyor System, comprising:
- a frame;
- a conveyor supported on said frame and having first and second ends for conveying material received in a vicinity of said first end to said second end where said material falls off said second end;
- apron having a width greater than that of said conveyor in said vicinity of said first end for receiving material from directions that span approximately 180 degrees about said vicinity of said first end;
- a first pusher blade having a concave face pivotally mounted adjacent a first side of said conveyor for sweeping a first arc along said apron to push material received on said apron onto said conveyor at said vicinity of said first end;
- said first pusher blade starting said first arc at a position approximately perpendicular to the movement of said conveyor;
- a second pusher blade having a concave face pivotally mounted adjacent a second side of said conveyor for sweeping a second arc along said apron to push material received on said apron onto said conveyor at said vicinity of said first end, said second pusher blade starting said second arc at a position approximately perpendicular to movement of said conveyor;
- an hydraulic prime mover for said pusher blades having first and second independently operable hydraulic cylinders depending on one end thereof, respectively, from said frame at first and seconds sides of said conveyor, and pivotally depending on another end thereof, respectively from said first and second pusher blades;
- a first roof extending from said first blade to cover said first hydraulic cylinder as said first pusher blade is swept through said first arc;
- and
- a second roof extending from said second blade to cover said second hydraulic cylinder as said second pusher blade is swept through said second arc.

A conveyor system, comprising:
- a frame;
- a conveyor having an inlet end and a discharge end for conveying material received in a vicinity of said inlet end to said discharge end;
- a transition assembly located at said discharge end of said conveyor for lessening the impact of large pieces of material when discharged from said conveyor, said transition assembly comprising:
- an incline ramp for receiving large pieces of material being discharge from said conveyor;
- openings in said ramp permitting small pieces of material being discharged from said conveyor to fall through said openings;
- an apron having a planar surface mounted on said frame adjacent said inlet end for receiving material;
- a first pusher blade having an outboard side edge and a pivot mount adjacent a first side of said conveyor adapted to pivot and sweep a first arc over said planar surface towards the vicinity of said inlet end for pushing said received material onto said conveyor at said vicinity of said inlet end;
- a second pusher blade having an outboard side edge and a pivot mount adjacent a second side of said conveyor adapted to pivot and sweep a second arc over said planar surface towards the vicinity of said inlet end for pushing said received material onto said conveyor at said vicinity of said inlet end;
- and
- an arcurate skirt affixed to said outboard edge of each of said pusher blades that extends upward from said planar surface to prevent material being swept from said planar surface from entering behind said pusher blades.
