  • the bucket 15 is free to function in the normal manner.
  • Latching the mechanism in the position as shown in FIG. 2 is accomplished by curling the bucket 15 upwards against the stick until the latch mechanism 24 engages the slot 25, at which time the latch mechanism is actuated, securing the materialfracturing apparatus into the position as shown in FIG. 2.
  • the latch mechanism 17 is then unlocked from bucket 15, permitting the bucket to swing away for use in the normal manner.
  • the material-fracturing device preferably includes a mechanism of the type shown in either one of US. application Ser. Nos. 390,911 entitled Eccentric Ring Impacting Mechanism or 390,912 entitled Impact Material Fracturing Device for Excavators and the Like both filed Aug. 23, 1973 of common assignment herewith, which are rotary impact devices and are preferably driven by rotary hydraulic motors.
  • the hydraulic motor is constructed as a sub-assembly generally designated by the numeral 26 and is readily detachable from the main housing and frame assembly of the fracturing apparatus.
  • the hydraulic motor sub-assembly 26 can be left latched in the position as shown in FIG. 3 and detached from the remainder of the assembly, permitting the fracturing apparatus housing and support frame to fall away as shown, so that it can be readily removed simply by removing bearing caps 18a from pivot pins 18.
  • This arrangement permits ready detachment of the fracturing apparatus without the possibility of contamination of the hydraulic oil supply. Such contamination would be possible if the hydraulic lines were required to be removed and capped upon removal of the assembly.
  • the apparatus can be reattached to the excavator simply by reversing the above process.
  • FIG. 4 wherein the device or apparatus is illustrated in a plan view, a housing 29 which encloses and mounts the drive shaft, flywheels and other related internal components, is rotatably supported by means of a main support member 30 and is adjustable with respect thereto by means of a pair of hydraulic cylinders 31 (SI. 32.
  • the internal mechanism of the impact material-fracturing apparatus including the fracturing shank 33 and fracturing tip 34 are similar to those disclosed in application Ser. No. 390,911 pointed out above.
  • the fracturing shank and mechanism is rotatable 40 to either side of its zero position. This selective adjustment is an important consideration when digging a trench through rock or hard substances.
  • the apparatus is capable of forming a trench with fairly vertical walls by rotating the cutting tool from side to side.
  • the housing portion 29 is pivoted with respect to the support structure 30 about a substantially vertical axis.
  • a pair of brackets 28 extend backward at approximately 45 with respect to this axis and are pivotally connected by means of the pin 18 to the stick 14.
  • the latching mechanism 17 for locking the impact apparatus to the bucket includes a latching rod 36 connected to a pivotally mounted bracket 37 at one end and a pivotal yoke member 38 at the other end, which yoke is connected in a suitable manner to a hydraulically actuated cylinder 39.
  • a locking detent member or wedge 40 is secured to the bucket as shown for engagement by the latching rod 36 to latch mechanism to the bucket.
  • the hydraulic cylinder 39 is actuated pivoting the yoke member 38 forward, which forces the latching rod 36 and bracket 37 downward to engage behind and lock to wedge member 40.
  • the hydraulic cylinder 39 is deactivated, which pulls the yoke 38 backward and latching rod 36 and bracket 37 upward out of engagement with the wedge member 40.
  • the latching mechanism 24 for latching the impact material fracturing apparatus 16 to the stick includes a bracket 42 having a pin member 43 secured to the bracket for engaging slot 25, formed in stick 14.
  • This latching mechanism is operated by means of a hydraulic cylinder 45 including piston rod 46 secured as illustrated to the C- shaped bracket 44.
  • Actuation of hydraulic cylinder 45 then forces the piston rod 46 forward and pivots C-shaped lock member 44 around pivot point 47, forcing the C-shaped members lower leg 48 to engage pin 43 and pull the entire mechanism upward against the stick until a stop member 49 engages the lower surface of the stick.
  • Hydraulic pressure is maintained in the cylinder 45 as long as the mechanism is in the latched position, as shown in FIG. 5 to provide a fail-safe lock system.
  • This latching mechanism as shown, 17 and 24, is duplicated on the other side of the bucket and stick.
  • the fail-safe lock system is provided between latch mechanisms 17 and 24 in order to ensure that the impact materialfracturing apparatus 16 is securely latched to the stick, by the latch mechanism 24 before the latching rods 36 can be unlocked from the bucket. This prevents the bucket from swinging away from the impact device without its being securely latched to the stick.
  • the interlock device also prevents the latch member 24 from being unlocked until the latching rod 36 is securely locked to the bucket.
  • This fail-safe latching and unlatching is accomplished through sequencing of various valves within the hydraulic circuit not shown.
  • FIG. 6 there is illustrated the mechanism for rotating or swinging the housing 29 about its pivot point with respect to the housing 30.
  • This assembly includes a pair of hydraulic cylinders 31 and 32 which are pivotally connected by suitable rods 52 and 53 which are pivotally connected to a rotator plate 54 which in turn is pivotally mounted within housing 29 by suitable pivot pin or the like 55.
  • the piston rods 52 and 53 are pivotally connected at 57 and 58 to the plate 54 which in turn engages a bracket 56 which is secured to the upper portion of the rotatable housing 29. Actuation of either one of the hydraulic motors 31 or 32 along with deactivation of the opposite motor pivots the housing 29 about the pivot support axis 55.
  • the apparatus to be pivoted about the pivot point 55 and the fracturing tool, as best seen in FIG. 4, to be swung to either side of the center line of the apparatus for engagement of walls to either side of the apparatus.
