Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic breaker hammers, in particular to a hydraulic breaker hammer with adjustable breaking depth. Background Art

[0002] A hydraulic breaker is an engineering tool used to break concrete, rock and other hard materials. It is generally composed of a drill rod and a hydraulic cylinder. A hydraulic breaker can effectively demolish concrete structures. By applying high-frequency impact force, it can quickly and accurately break concrete, making it easy to clean and carry, speeding up the demolition process and reducing labor costs, helping to complete the task of breaking and cleaning hard materials.

[0003] Hydraulic breakers can be used for projects such as demolishing concrete structures of buildings, crushing rocks and maintaining road surfaces. The drill rod of the hydraulic breaker is subjected to the force of the hydraulic cylinder and contacts the surface of the workpiece, generating a high-frequency impact force, thereby crushing concrete, rock or other hard materials. For harder rocks or concrete, hydraulic breakers generally require a deeper crushing depth to completely crush them, while for softer materials, generally only a shallower crushing depth is required. Therefore, the staff needs to replace the hydraulic breaker according to the materials of different hardness and thickness to adjust the crushing depth. Since more fastening bolts need to be removed when replacing the hydraulic breaker, the replacement takes a certain amount of time, making it inconvenient for the hydraulic breaker to quickly adjust the crushing depth. Therefore, we propose a hydraulic breaker with adjustable crushing depth. Utility Model Content
