Simple SummaryContent extracted from patent full text and abstract with AI.

This invention relates to an advanced machine chisel (specifically for use in mining, construction, and similar material-removal processes) equipped with a reference body that integrates a sensor-detectable magnetic scale. The chisel and its holder include sensors that allow for contactless measurement of the chisel's movement, force application, and wear during operation. The system enables real-time monitoring and analysis of both the processed material properties (such as hardness) and the chisel’s own condition, allowing selective and optimized material removal even under low visibility conditions.

Use CasesContent extracted from patent full text and abstract with AI.

  • Mining operations for selective extraction of valuable minerals with minimal waste.
  • Tunnel, trench, or road construction where various rock or ground conditions must be monitored and responded to in real time.
  • Demolition or building site excavation, allowing on-the-fly adaptation to material hardness and reducing unnecessary tool and machine wear.
  • Implementation in autonomous or remotely operated excavation systems, removing the need for skilled manual visual assessment.
  • Real-time monitoring and automatic adjustment of machine parameters (pressure, speed) based on detected material properties.
  • Maintenance scheduling and predictive diagnostics based on wear detection of the chisel.

BenefitsContent extracted from patent full text and abstract with AI.

  • Enables more efficient, safer, and cost-effective selective mining or excavation by providing continuous, objective information about the material being processed.
  • Reduces downtime and interruptions otherwise needed for visual inspections by operators, thus increasing productivity.
  • Minimizes dilution of extracted minerals with waste materials, improving the value and ease of post-processing and reducing overall operational costs.
  • Automates or assists material property detection independent of operator experience and environmental conditions (such as dust or debris).
  • Facilitates predictive maintenance through early detection of chisel wear, potentially extending tool and holder lifespan and lowering replacement costs.
  • Enhances process optimization, enabling adaptive and potentially autonomous excavation or cutting machines for various ground and material conditions.

Patent Abstract

The invention relates to a machine chisel (100), a retaining device (300), a removing system (600) and a method. The machine chisel (100) can comprise: a chisel tip (102); a shank (104), which extends away from the chisel tip along a longitudinal axis (107) of the machine chisel; and a reference body (106), which has at least one scale (112) which is made of a magnetisable material and can be detected by sensors, the reference body, the shank and the chisel tip being rigidly connected to one another. The retaining device (300) can comprise: a chisel holder (302) having an opening (316) to receive a machine chisel; a locking device (202, 402) which is designed to make a form fit with the machine chisel received in the opening, thereby limiting movement of the machine chisel; a receiving region (320) to receive a portion of the machine chisel, the accommodating region being exposed relative to the opening; and at least one sensor (306), which is disposed on the receiving region and is designed to contactlessly detect the portion extending into the receiving region, and/or the reference body (106) being designed to be connected to the shank (104) with a form fit.
