Abstract
The present invention discloses a method and apparatus for excavating material from a mining or reclamation operation, and is generally considered useful in open cast mining operations. The apparatus has a first conveyor and a second conveyor attached to a chassis. The first conveyor is fitted with a material remover such as a excavator bucket on a first end. Material discharges from the first conveyor onto a second conveyor which is generally longitudinally aligned with the first conveyor and has a material receiving point located elevationally below the discharge point of the first conveyor.
Claims35
An earthen material conveyor system comprising first and second longitudinally elongated conveyors having respective ends, one of the first conveyor ends comprising a discharge end which is positioned elevationally over the second conveyor to enable transfer of earthen material from the first conveyor to the second conveyor, the first conveyor being movably supported on opposing sides of the second conveyor to enable selective positioning of the first conveyor one end at different longitudinal locations along the second conveyor.
An earthen material conveyor system comprising first and second longitudinally elongated conveyors having respective ends, the first conveyor having one of its ends positioned elevationally over the second conveyor to enable transfer of earthen material from the first conveyor to the second conveyor, the first and second conveyors being mounted relative to one another along a common line, the first conveyor being movably mounted relative to the second for longitudinal movement along the common line to enable selective longitudinal overlap of the first conveyor relative to the second and selective positioning of the first conveyor one end at different longitudinal locations along the second conveyor during operation.
A material transfer machine for moving material from a first location to a second location, comprising:
- a. a chassis;
- b. a first material transport and a second material transport, said first material transport and said second material transport supported by said chassis, said first material transport configured to move with respect to said second material transport, wherein said first material transport has a first end and a second end, said first material transport first end positioned with respect to said second material transport to allow said material to be discharged from said first material transport onto said second material transport;
- c. a material remover, said material remover disposed at said second end of said first material transport and configured to deposit material removed by said material remover onto said first material transport;
- and
- d. a first material transport drive connected to said first material transport and configured to move said first end of said first material transport with respect to said second material transport and said chassis.
An excavator comprising:
- a. a chassis;
- b. an arm conveyor and a first discharge conveyor, said arm conveyor and said first discharge conveyor supported by said chassis, said arm conveyor moveable with respect to said first discharge conveyor, wherein said arm conveyor has a first end and a second end, said arm conveyor first end positioned with respect to said first discharge conveyor to allow said material to be discharged from said arm conveyor onto said first discharge conveyor, said arm conveyor further comprising:
- i. a material remover, said material remover disposed at said second end of said arm conveyor;
- and
- ii. an arm conveyer belt for moving material along said arm conveyor;
- wherein said material remover is configured such that material removed by said material remover is deposited onto said arm conveyor belt;
- c. an arm conveyor drive connected to said arm conveyor to cause movement of said first end of said arm conveyor with respect to said second conveyor and said chassis;
- and
- d. an arm conveyor second end positioner for elevationally positioning said second end of said arm conveyor, said arm conveyor second end positioner supported by said chassis.
Method for moving earthen material from a first location having an exposed material face to a second location, comprising:
- a. removing said material from said exposed material face with a material remover by moving said material remover along said material face;
- b. moving said removed material onto a first material transport at a first material receiving point;
- c. conveying said material on said first material transport to a first material discharge point;
- d. discharging said material onto a second material transport at a second material receiving point;
- and
- e. discharging said material from a first end of said second material transport;
- wherein said first material discharge point moves in response to movement of said material remover to effectively vary said second material receiving point.
