The utility model discloses an ellipse-like hyperbolic coal bunker funnel. The funnel comprises a hyperbolic curve funnel and an ellipse-like conical funnel, the hyperbolic funnel is arranged above the ellipse-like conical funnel; the lower end of the hyperbolic funnel is communicated with the upper end of the ellipse-like conical funnel; the lower part of the ellipse-like conical funnel is gradually transited from a circle to a rectangle; the wall surface angle of the ellipse-like conical funnel is not less than the maximum value of the wall surface angle of the upper funnel part; through thestructural design of the hyperbolic curve funnel and the ellipse-like conical funnel, the situation that coal is stored in the ellipse-like hyperbolic curve coal bunker funnel can be effectively avoided, normal operation of coal bunker coal caving operation is further guaranteed, and in conclusion, the coal bunker coal caving device has the advantages of being high in coal caving efficiency, thorough in coal bunker coal
