ABSTRACT:
A heated bucket system for significantly reducing the accumulation of frozen mud and ice within a bucket thereby maintaining the bucket's dirt moving capacity. The inventive device includes a bucket attachable to an arm of a backhoe or other machinery, a pump attached to the coolant system of the backhoe, an inflow tube fluidly connected to the pump, a heat tube attached to the back member of the bucket preferably in a sinusoidal pattern and fluidly connected to the inflow tube, and an outflow tube fluidly connected to the heat tube opposite of the inflow tube and fluidly connected to the coolant system of the backhoe. In operation, the pump draws the heated coolant within the coolant system and pumps it through the heat tube attached to the bucket. The heat from within the coolant is exchanged with the bucket thereby maintaining the temperature of the bucket above freezing. The coolant is then returned to the coolant system through an outflow tube. The heated bucket prevents the mud and water from freezing within the bucket during operation thereby maintaining the earth moving capacity of the backhoe in cold weather conditions. The invention also operates to maintain earth moving capacity during warm weather conditions by preventing the accumulation of mud and sticky dirt.
