Abstract
A scraper assembly for a construction machine includes a housing pivotally coupled to a frame of the construction machine for moving the scraper assembly between a stowed position and a deployed position. The scraper assembly also includes a scraper partially received within the housing. In the deployed position of the scraper assembly, the scraper engages with a machine component to remove material stuck to the machine component. The scraper assembly further includes a biasing device received within housing. The biasing device biases the scraper towards the machine component. Further, the biasing device travels in a substantially linear path for biasing the scraper towards the machine component.
Claims16
A scraper assembly for a construction machine, the scraper assembly comprising:
- a housing pivotally coupled to a frame of the construction machine to move the scraper assembly between a stowed position and a deployed position;
- a scraper partially received within the housing, wherein, in the deployed position of the scraper assembly, the scraper engages with a machine component to remove material stuck to the machine component;
- a biasing device received within the housing, wherein the biasing device biases the scraper towards the machine component, and wherein the biasing device travels in a substantially linear path for biasing the scraper towards the machine component;
- and
- a mounting assembly to removably couple the scraper to the housing,
- wherein the mounting assembly includes an adjustment tab to move the biasing device to a compressed state.
A method of operating a scraper assembly for removing material from a machine component of a construction machine, the method comprising:
- moving the scraper assembly from a stowed position to a deployed position, wherein the scraper assembly includes a housing, a scraper partially received within the housing, and a biasing device received within the housing to bias the scraper towards the machine component, and wherein the biasing device travels in a substantially linear path to bias the scraper towards the machine component;
- engaging the scraper with the machine component to remove material from the machine component based on the biasing of the scraper by the biasing device;
- and
- engaging an adjustment tab of the assembly with a retention device associated with the housing to hold the biasing device in a compressed state.
A wear indication system associated with a scraper of a construction machine, wherein the scraper engages with a machine component to remove material stuck to the machine component, the wear indication system comprising:
- a wear sensor cooperating with the scraper, wherein the wear sensor generates an input signal indicative of a wear condition of the scraper;
- and
- a controller communicably coupled to the wear sensor, wherein the controller is configured to:
- receive the input signal indicative of the wear condition of the scraper;
- and
- generate a notification corresponding to the wear condition of the scraper based on the receipt of the input signal,
- wherein the construction machine includes:
- a housing pivotally coupled to a frame of the construction machine to move a scraper assembly between a stowed position and a deployed position, wherein the scraper is partially received within the housing;
- and
- a biasing device received within the housing, wherein the biasing device biases the scraper towards the machine component, and wherein the biasing device travels in a substantially linear path to bias the scraper towards the machine component,
- wherein the scraper assembly further includes a mounting assembly to removably couple the scraper to the housing, and
- wherein the mounting assembly includes an adjustment tab to move the biasing device to a compressed state.
