Abstract
A hydraulic hammer for a working machine configured for digging a surface includes a housing, a chisel, sensors, and a controller. The housing is coupled to the working machine. The chisel is partially enclosed by the housing and extendable from the housing for digging the surface at a contact location. Each of the sensors is configured for generating a signal indicative of a projecting distance between one of the sensors and the surface. The controller is configured for receiving the signals, determining an angle between the chisel and a plane substantially tangent to the contact location, and reorienting the chisel so that the chisel is substantially orthogonal to the contact location with the angle at substantially ninety degrees.
Claims14
A method to adjust a hydraulic hammer of a working machine digging at a contact location of a surface at optimal degrees, comprising:
- providing a housing of the hydraulic hammer having a bottom surface including an aperture;
- providing a chisel partially enclosed by the housing and extendable from the aperture for digging the surface;
- providing a first sensor and a second sensor positioned on the bottom surface of the housing;
- generating a first signal indicative of a first projecting distance between the first sensor and the surface;
- generating a second signal indicative of a second projecting distance between the second sensor and the surface;
- receiving the first signal and the second signal;
- determining an angle between the chisel and a plane tangent to the contact location of the surface based on the first signal and the second signal;
- and
- reorienting the chisel, if the angle is not at the optimal degrees, until the angle is at the optimal degrees.
