MATERIAL PICKUP FOR GROOVE CUTTERS Grooving of airport runways for drainage of water and grooving of roads, streets and highways at curves and at intersections for better traction have become increasingly important. The slurry that is left on the grooved surface by the grooving machine has, however, presented a difficult problem, not heretofore satisfactorily solved.
An important object of my present invention, therefore, is to provide apparatus for removing the slurry, eliminating all hazard, not only in the wet substance, but in the dust that remains after drying.
Another important object of the instant invention is to provide such apparatus as a part of the groove cuttingmachine itself.
Still another important object of the present invention is the provision of structure which advantageously utilizes the inherent movement of the slurry itself in the continuous removal thereof as the grooves are being cut, eliminating the need, therefore, of complicated and expensive pickup equipment either as a part of or separate from the groove cutting machine.
In the drawing:
FIG. l is a fragmentary, vertical cross-sectional view of a groove cutting machine, illustrating the' pickup of the instant invention in front elevation;
FIG. 2 is a fragmentary, vertical cross-sectional view of the machine showing the pickup in rear elevation, parts being broken away and in section for cleamess; and
FIG. 3 is an enlarged, fragmentary cross-sectional view taken on line 3-3 of FIG. 1.
Apparatus for removing particles of material produced by cutter 12 during cutting of grooves 24 in surface 26 includes a manifold 32 for supplying cutter 12 with a cooling liquid, such as water. Manifold 32 is shown spaced behind the circular peripheries 14a of discs 14 in parallelism with and at a lower elevation than the axis of rotation of shaft 16, but spaced above surface 26. Manifold 32 has a series of spaced nozzles 34 inclined downwardly and forwardly for directing streams 36 of the cooling water to the discs 14 at the zones of cutting of grooves 24.
The material-removing apparatus includes additionally structure disposed to contain within limited bounds the liquid 36 and the particles of material removed by discs 14 as the latter cause centrifugal projection of the liquid and material. Such structure includes an elongated, open bottom hood 38 that is generally semicircular in transverse cross section. Hood 38 overlies the cutter 12 in diametrically opposed relationship to surface 26 so as to partially shroud cutter 12, and is spaced radially outwardly from the peripheries 14a of discs 14. End walls 48 of hood 38 have downwardly opening notches 42 for clearing shaft 16 and lowermost edges 44 and 46 spaced above surface 26. Particles of material and water collecting on walls 48- are prevented from escaping from hood 38 through notches 42 (FIG. 2) by inwardly flared flanges or troughs 48 formed on the inner surfaces of walls and looped over shaft 16.
Lowermost and rearmost longitudinal edge 50 of hood 38 is spaced above streams 36, forwardly of manifold 32 and rearwardly of peripheries 14d, whereas lowermost and forwardmost edge 52 of hood 38 is spaced forwardly of peripheries 14a at the elevation of edges 46. Hood 38 has a flexible apron 64 secured thereto by fasteners 56 and depending from edge 52 into wiping engagement with surface 26. Flexible side panels 58 are secured to walls 40 by fasteners 60 and depend from edges 46 into sliding engagement with surface 26. A longitudinally extending outlet 62 in hood 38 is disposed above apron 54.
The material-removing apparatus includes still further collector means disposed to receive the liquid and the material from the hood 38, taking the form of a pair of open top containers 64 and 66, spaced above surface 26. Container 64 is spaced rearwardly of peripheries 14a and extends between walls 40 with its rear wall 68 depending from edge 50 and its bottom 70 sloping toward a central outlet 72 in wall 68, from which outlet 72 the material and water are continuously pumped. Container 66 is disposed forwardly of apron 54 below outlet 62 and has its bottom 74 sloping toward an outlet 76 in front wall 78, here again the material and water being continuously pumped from container 66 via outlet 76.
Means is provided for stripping the cutter 12 of liquid and material tending to rotate therewith around its axis of rotation. Such means includes a first plate 80 between walls 40, notched to clear discs 14, extending upwardly and forwardly from the upper edge of front wall 82 of container 64, and terminating on the outer, circumferential annular surfaces of spacers 28 tangentially to the latter. A second plate 84 between walls 40 above plate 80, similarly notched and disposed, has a slightly different angularity than plate 80. A third plate 86 between walls 40 extends downwardly and rearwardly from the upper edge of outlet 62, is similarly notched and at a tangent to spacers 28. All three plates 80, 84 and 86 strip the water and material from the side faces of discs 14, from their peripheries 14a and from the spacers 28.
A top wall 88 and end walls 90 join hood 38 with wall 78, walls 90 also closing the ends of container 66. An inclined plate 92 between walls 40 depends from the lowermost edge of plate 84 between hood 38 and peripheries 12a, terminating at the container 64.
In operation, the discs 14 pickup the water 36 and the material removed from surface 26 in forming grooves 24 and project the slurry thus produced upwardly and forwardly of discs 14 at a tangent by action of centrifugal force. Much of the slurry passes to the container 66 via outlet 62, and that which revolves beyond the plate 86 is carried toward the plate 84. Slurry removed by plate 84 is directed into container 64 by plate 92. Such slurry as revolves beyond plate 84 is directed into container 64 by plate 80. The slight amount of slurry that escapes plate 80 is redirected into the cycle by the streams of water 36. As a result, the grooved surface 26 and the grooves 24 themselves are left essentially free of the particles of material removed by the cutting action of discs 14 and while the grooved surface 26 remains damp, there is virtually no film of water left thereon, and very little slurry left in grooves 24.
The means for pumping the slurry from containers 64 and 66 into a collection tank, the means for directing water under pressure to manifold 32 from a supply tank, the drive for shaft 16, the means for raising and lowering cutter 12, and the prime mover for advancing machine 10 form no part of the present invention and have, therefore, not been shown.
