Hydraulic hammer device for excavators

Abstract

A hydraulic hammer device for excavators comprising at least one ripper ( 1 ) and an energy accumulator ( 4 ); where the energy accumulator ( 4 ) is located on the longitudinal shaft of the ripper ( 1 ) and integrally connected to said ripper ( 1 ); and where said shaft is on that which attacks the ground between the retracted and deployed positions of the ripper ( 1 ) and which is characterized in that it comprises a cylinder ( 2 ) or two cylinders ( 2,3 ) integrally connected to the ripper ( 1 ) inside same.

1 . A hydraulic hammer device for excavators comprising at least one ripper ( 1 ) and an energy accumulator ( 4 ); where the energy accumulator ( 4 ) is located on the longitudinal shaft of the ripper ( 1 ) and integrally connected to said ripper ( 1 ); and where said longitudinal shaft of the ripper ( 1 ) is on that which attacks the ground between the retracted and deployed positions of the ripper ( 1 ) and characterized in that it comprises at least one cylinder ( 2 ) connected to the ripper ( 1 ) and longitudinally aligned with the said longitudinal shaft of the ripper. 
     
     
         2 . The device according to  claim 1 , wherein the cylinder ( 2 ) is housed inside the ripper ( 1 ) in a space ( 13 ) provided for such purpose in a position longitudinally aligned with the shaft which attacks the ground (F 1 ), such that said cylinder delivers blows to the body of the ripper ( 1 ) itself in a region of impact ( 14 ). 
     
     
         3 . The device according to  claim 1  comprising at least two cylinders ( 2 , 3 ) integrally connected to the ripper ( 1 ) and housed therein forming between them an angle the vertex of which coincides with the shaft which attacks the ground (F 1 ); and where each of said cylinders ( 2 , 3 ) comprises an energy chamber ( 21 , 31 ), said energy chambers ( 21 , 31 ) of the cylinders communicating with one another ( 22 ), such that they allow alternating movement of both cylinders ( 2 , 3 ). 
     
     
         4 . The device according to  claim 3 , wherein the cylinders ( 2 , 3 ) are arranged with respect to one another such that the force vector (F 2 ,F 3 ) of both cylinders ( 2 , 3 ) is oriented towards one and the same point coinciding with the attack vector (F 1 ) which attacks the bottom of the ripper. 
     
     
         5 . The device according to  claim 3 , wherein the point coinciding with the attack vector (F 1 ) which attacks the bottom of the ripper coincides with the connection point ( 12 ) of the tooth ( 11 ) with the ripper ( 1 ). 
     
     
         6 . The device according to  claim 3 , where the cylinders ( 2 , 3 ) deliver blows to the body of the ripper ( 1 ) itself in a region of impact ( 14 ). 
     
     
         7 . The device according to  claim 2 , wherein said region of impact ( 14 ) is a dolly integrally connected to the ripper ( 1 ). 
     
     
         8 . The device according to  claim 1  comprising at least one control element for controlling the passage of oil to the cylinders ( 2 , 3 ). 
     
     
         9 . The device according to  claim 1 , where the energy accumulator ( 4 ) is integrally connected between the body of the ripper ( 1 ) and the head ( 5 ) of the machine. 
     
     
         10 . The device according to  claim 7 , wherein the energy accumulator ( 4 ) is an air cushion.
