Abstract
The apparatus for clearing a trafficked surface such as a road, express highway and airport runway of snow, slush, water, dirt and the like comprises a framework in which two rotatable drums are mounted and around which a conveyor belt for the material to be cleared movable transverse to the direction of travel or inclined in the operating location is guided. The conveyor belt is movable into a position inclined at an acute angle with respect to the normal of the trafficked surface. One of two strands of the conveyor belt is contactable on the trafficked surface while the other oppositely movable strand of the conveyor belt is liftable from the trafficked surface.
Claims39
ln an apparatus for clearing a traveled surface such as a road, express highway and airport runway of such material as snow, slush, water, dust, dirt and other debris comprising a framework supporting two rotatable drums, a conveyor belt surrounding said drums for removing the material to be cleared, and a means for moving said belt transverse to the direction of travel, the improvement wherein said means is capable of moving the conveyor belt into a position inclined at an acute angle with respect to the normal of said traveled surface, one of two belt stretches of said conveyor belt being contactable on said traveled surface while the other oppositely movably belt stretch of said conveyor belt being liftable from said traveled surface.
In an apparatus for clearing a traveled surface such as a road, express highway and airport runway of such material as snow, slush, water, dust, dirt and other debris comprising a framework supporting two rotatable drums, a conveyor belt surrounding said drums for removing the material to be cleared, and a means for moving said belt transverse to the direction of travel, the improvement wherein said means is capable of moving the conveyor belt into a position inclined at an acute angle with respect to the normal of said traveled surface, one of two belt stretches of said conveyor belt being contactable on said traveled surface while the other oppositely movable belt stretch of said conveyor belt being liftable from said traveled surface, a plurality of guide rollers for said conveyor belt are mounted in said framework in addition to at least two of said rotatable drums for said conveyor belt and the inner side of said conveyor belt has a longitudinally extending profiling including a plurality of means for maintaining positioning of said belt on said guide rollers which means are selected from the group consisting of ribs, grooves and mixtures thereof and the outer surface of said guide rollers is also provided with a circular sectioning including a plurality of complementary means, which complementary means is selected from the group consisting of ribs, grooves and mixtures thereof spaced from each other opposite said longitudinally extending profiling on said conveyor belt.
In an apparatus for clearing a traveled surface such as a road, express highway and airport runway of such material as snow, slush, water, dust, dirt and other debris comprising a framework supporting two rotatable drums, a conveyor belt surrounding said drums for removing the material to be cleared, and a means for moving said belt transverse to the direction of travel, the improvement wherein said means is capable of moving the conveyor belt into a position inclined at an acute angle with respect to the normal of said traveled surface, one of two belt stretches of said conveyor belt being contactable on said traveled surface while the other oppositely movabIe belt stretch of said conveyor belt being liftable from said traveled surface, said framework supporting a blower for moving by air manipulation the material to be cleared, an air duct open to said traveled surface which is connectable by a support pipe to said blower is provided on said framework between said conveyor belt extending over the length of said framework.
In an apparatus for clearing a traveled surface such as a road, express highway and airport runway of such material as snow, slush, water, dust, dirt and other debris comprising a framework supporting two rotatable drums, a conveyor belt surrounding said drums for removing the material to be cleared, and a means for moving said belt transverse to the direction of travel, the improvement wherein said means is capable of moving the conveyor belt into a position inclined at an acute angle with respect to the normal of said traveled surface, one of two belt stretches of said conveyor belt being contactable on said traveled surface while the other oppositely movable belet stretch of said conveyor belt being liftable from said traveled surface, said framework supports a means for moving by air manipulation the material to be cleared, said means selected from the group consisting of a blower and suction device, an air conduit opening downwardly is held by said framework, and a support pipe including two branches, each of the two branches of said support pipe being conducted to each end of said air conduit opening downwardly, a controlling cover being located at the mouth of said support pipe and each of said branches.
