Abstract

A vehicular truck equipped for road repair work is described, including a repair materials hopper, a front discharge chute and a drive worm conveyor mechanism for transporting road repair material from the hopper through the chute for deposit in a pavement '"'"''"'"''"'"''"'"'pothole'"'"''"'"''"'"''"'"' or the like to be repaired, is described. The discharge end of the material chute carries a rake movable up and down, from side-to-side and from front-to-back, through the use of hydraulic piston control mechanism controllable by a single operator in the truck cab, for spreading the deposited material evenly over the pavement defect being repaired. A hydraulically controlled roller, also controlled by the single operator in the cab, is mounted at the rear end of the truck for use in rolling the deposited and raked repair material to complete the road repair operation.

Claims

1. In a road repair truck, the combination comprising a vehicle frame, a pair of front wHeels and a pair of back wheels rollably supporting said vehicle frame, a road repair materials hopper having inclined sides and a rounded bottom supported upon said vehicle frame, a conveyor screw in said rounded bottom, means for driving said screw, conveyor tube means communicating with the rounded bottom of said hopper and extending from the forward end of said hopper, a flexible discharge chute connected to the forward end of said conveyor tube means and having a discharge end extending downwardly over the front end of said vehicle frame for dispensing road repair material therefrom, said conveyor screw conveying road repair material from said hopper to said discharge chute for deposit in a pavement hole to be repaired, a rake device secured to the discharge end of said discharge chute, piston means for moving said discharge end and said rake comprising three hydraulic piston cylinders, one for side-to-side motion, one for front-to-back motion and one for up-and-down action, said hydraulic piston cylinders being arranged to move said deposit end with respect to the forward end of said vehicle for evenly depositing and raking road repair material, control means from operator station on the vehicle whereby road repair material may be fed to the repair area by operation of said conveyor screw and proper positioning of said discharge end of said discharge chute whereby the discharge materials may be raked by said rake into said repair area, and roller means including control means therefor for compacting said road repair material to complete a repair of a pavement.

2. In a road repair truck as defined in claim 1, including means on the rear of said truck to retract and lower said roller into position to roll and smoothly compact said road repair material to conform to the contour surface of said pavement.

3. In a road repair truck as defined in claim 1, including heating means along the length of the rounded bottom portion of said hopper.

4. In a road repair truck as defined in claim 1, wherein said rake is of V-shape and is secured to the rectangular discharge end of said discharge chute.

5. A road repair truck as defined in claim 1, wherein said material conveyor screw comprises an elongated worm driven member rotatably journalled in the bottom of said hopper, and a conveyor tube communicating at the one end with said bottom of said hopper in coaxial alignment with said worm driven member, the other end of said conveyor tube being in communication with the inlet end of said chute.

6. A road repair truck as defined in claim 1, wherein said conveyor tube extends substantially horizontally to the front of said vehicle frame, and wherein said discharge chute is of arcuate shape along its length with its discharge end facing the road surface over which the repair truck moves.

7. A road repair truck as defined in claim 1, wherein said operators station comprises an operator'"'"''"'"'s cab having transparent panels therein mounted at the front and to one side of said vehicle frame, said chute moving means further comprising manually actuatable means for individually controlling said hydraulic piston cylinders.
