Abstract
A conveyor is rotatably mounted to a vehicle. The conveyor includes a plurality of frame members pivotally coupled to one another, such that they can be placed in overlapping relationship for transport with the vehicle or unfolded for use. An extension member is slidably coupled to one of the frame members such that the conveyor can be extended beneath a rail car for receiving material therefrom.
Claims19
A conveyor system including a conveyor and a power vehicle, said conveyor being coupled to said vehicle and comprising:
- a first section having first and second portions;
- a second section slidably coupled to the second portion of said first section and having a forward end portion and a rearward end portion;
- a conveyor belt extending about said first and second sections;
- a hinge that pivotally couples said first and second portions;
- a first link pivotally coupled to said first portion along a first axis;
- a second link pivotally coupled to said first link along a second axis and to said second portion along a third axis;
- and
- a rod coupled to said first link along a fourth axis and adapted for coupling to a reciprocating drive for pivoting said first link about said first axis.
A conveyor system including a conveyor and a powered vehicle, said conveyor being coupled to said vehicle and comprising:
- a first section having first and second portions;
- a second section slidably coupled to the second portion of said first section and having a forward end portion and a rearward end portion;
- a first roller coupled to said second portion adjacent said second section;
- a second roller coupled to said rearward portion;
- a third roller coupled to said forward portion;
- an endless conveyor belt extending about said first and second sections and around said rollers;
- a brake directly coupled to said second roller for preventing rotation thereof when said brake is in a first position and permitting rotation of said second roller when said brake is in a second position;
- and
- a member positioned over said conveyor belt in the vicinity of the juncture between said first and second sections for preventing significant belt movement away from said sections.
A conveyor system including a conveyor and a powered vehicle, said conveyor being coupled to said vehicle and comprising:
- a conveyor belt;
- a first section having first and second portions and rollers arranged in a trough configuration, said rollers supporting a portion of said conveyor belt;
- a second section slidably coupled to the second portion of said first section and having a forward end portion and a rearward end portion, said second section having a rollerless support surface that supports a portion of said belt.
A conveyor system including a conveyor and a powered vehicle, said conveyor being coupled to said vehicle and comprising:
- a first section having first and second portions;
- a second section slidably coupled to the second portion of said first section and having a forward end portion and a rearward end portion;
- a first roller coupled to said second portion adjacent said second section;
- a second roller coupled to said rearward portion;
- a third roller coupled to said forward portion;
- an endless conveyor belt extending about said first and second sections and around said rollers;
- a brake directly coupled to said second roller for preventing rotation thereof when said brake is in a first position and permitting rotation of said second roller when said brake is in a second position;
- and
- a support member having one side rotatably coupled to said vehicle and another side coupled to said conveyor such that said conveyor can be rotated to one position during transport and another during use.
