Abstract
A flexible track conveyor apparatus for cutting a surface of concrete, particularly, green concrete. The apparatus includes a frame with first and second track conveyors disposed at opposed lateral sides thereof and with a blade mount for mounting a rotatable cutting blade disposed between the first and second track conveyors. The apparatus may also include conventional features such as a motor and a handle.
Claims20
An apparatus for cutting a surface of concrete over which the apparatus is conveyed, the apparatus comprising:
- a frame having opposed and spaced apart lead and trail ends, the frame also having opposed and spaced apart first and second lateral sides;
- a first flexible track conveyor assembly generally disposed along the frame first lateral side, the first flexible track conveyor assembly including a first endless flexible track conveyor disposed about first track supports along the frame first lateral side, wherein the first track supports consist essentially of supports fixed relative to the frame;
- a second flexible track conveyor assembly generally disposed along the frame second lateral side, the second flexible track conveyor assembly including a second endless flexible track conveyor disposed about second track supports along the frame second lateral side, wherein the second track supports consist essentially of supports fixed relative to the frame;
- a blade mount disposed between the first and second endless flexible track conveyors, the blade mount for mounting a rotatable cutting blade effective to cut concrete and permitting vertical adjustment of the rotatable cutting blade relative to the frame;
- a motor in operational communication with the rotatable cutting blade effective to rotate the cutting blade to cut into the surface of concrete over which the apparatus is conveyed;
- a motor in operational communication with the first and second track conveyor assemblies effective to rotate the first and second flexible track conveyors, respectively;
- and
- a handle fixedly connected to the frame and effective for guiding the apparatus across a surface of concrete to be cut.
