Abstract
A cooling system for cooling the cutting edge of an impact type ripper tip includes a source of liquid coolant under pressure and conduit means for supplying the coolant to a spray head mounted below and behind the ripper tip in a position to distribute liquid coolant to the lower surface of the tip behind the cutting edge. The spray head is detachably mounted directly behind the ripper tip and projects downward beyond the lower surface of the tip.
Claims21
In an impact rock ripping machine having an elongated and downwardly extending ripping shank with a forwardly extending [rip] tip mounted on said machine for receiving intermittent impact blows for driving the shank and tip in a forward direction at intermittent high speed intervals the improvement comprising:
- cooling means for distributing a flow of coolant to said tip for controlling the temperature thereof comprising a spray head mounted beneath said shank and disposed intermediate lateral sides thereof and behind said tip and having a plurality of spray openings positioned thereon to direct a spray pattern of coolant to an underside of said tip and fully thereacross;
- an adapter having a first socket receiving a forwardly extending projection of said shank in mounting relationship therein and a second socket having said tip detachably mounted therein;
- and
- spray head mounting means on said adapter mounting said spray head thereon, adjacent to said tip.
In an impact rock ripping machine,
- a ripping shank,
- an adapter mounted on a forward end of said shank,
- A tip detachably mounted on a forward end of said [adapted] adapter , and
- cooling means for distributing a flow of coolant to said tip for controlling the temperature thereof comprising
- a pressurized source of coolant,
- a spray head mounted beneath said shank and [havng] having a plurality of openings positioned thereon for directing [coolabt] coolant forwardly and across an underside of said tip,
- means for communicating coolant from said source to said openings, and
- spray head mounting means comprising a slot having sloping sidewalls formed in said adapter and sloping sidewalls formed on said spray head and engaging the sloping sidewalls formed in said adapter for being retained in position thereby.
In an earth cutting apparatus having a cutting tool, said cutting tool having a cutting edge terminating forwardly at the juncture of a pair of side surfaces lying in a pair of laterally spaced planes, a top surface, and a bottom surface of predetermined width and length, the improvement comprising:
- means for spraying and directly impinging pressurized coolant across the full width of said bottom surface and the full width of said cutting edge, said bottom surface being defined as that portion of the tool in contact with the unsevered earth during a cutting operation of said apparatus and said means located between the planes having said side surfaces lying therein.
In an impact rock ripping machine
- a support member having a predetermined width and mounted on said machine,
- tip means mounted forwardly of said support member for penetrating hard materials and having forwardly converging top and bottom surfaces and a pair of side surfaces lying in a pair of laterally spaced planes terminating at a narrow cutting edge extending across the full width of said tip means, said cutting edge being at least as wide as the width of said support member, and
- cooling means mounted directly rearwardly of said cutting edge and fully exposed to said bottom surface for spraying and directly impinging pressurized coolant in a fanlike pattern across the full width of said bottom surface in the plane thereof and directly across the full width of said cutting edge, said cooling means located between the planes having
- said side surfaces lying therein.
