Abstract
The invention provides an asphalt patching device capable of single-handed operation, reducing the time and expense of conventional asphalt patching. The device comprises an auger, a hopper with an associated spreader, a conveyor to transport asphalt from the auger to the hopper, and an operator's station. This device, exclusive of the hopper, is mounted to a wheeled frame which is pulled behind a dump truck carrying the asphalt. The frame is provided with wheels which permit the device to rotate substantially 180.degree. side-to-side behind the truck in order to effect asphalt patches on a roadway.
Claims19
An asphalt patching device comprising:
- a. an auger adapted to be affixed to the tailgate of a dump truck so as to deliver asphalt from said dump truck;
- b. hopper means affixed to a wheeled frame which is removably attached to said dump truck, the hopper being adapted to distribute asphalt to a location to be patched;
- c. at least one conveyor positioned to deliver asphalt from said auger to said hopper;
- d. rotatably adjustable spreader means affixed to the underside of said hopper, said spreader means being rotatable about a vertical axis disposed through the hopper and spreader means, and
- e. the spreader means being vertically adjustable relative to and independent from the wheeled frame.
The device as recited in claim 7, wherein said spreader means further comprise vertically adjustable transversely disposed scraper means which defines the vertical thickness of an asphalt patch.
An asphalt patching device having a longitudinal axis coinciding with a direction of travel and a transverse axis perpendicular thereto, comprising:
- a. an auger mounted about said transverse axis and adapted to be affixed to the tailgate of a dump truck, said auger having at least one exit port for distribution of asphalt from said dump truck;
- b. hopper means affixed to a wheeled frame, said hopper comprising means for receipt and distribution of asphalt to an area to be patched;
- c. at least one conveyor having a receipt end to receive asphalt from said auger and a discharge end to discharge asphalt into said hopper;
- and
- d. vertically and rotatably adjustable spreader means affixed to said hopper, said spreader means being rotatable about a vertical axis disposed through the hopper and spreader means, such that the transverse dimension and the thickness of an asphalt patch can be varied.
