Electric mechanical feeding device used for mixing hydraulic concrete

The invention provides an electric mechanical feeding device used for mixing hydraulic concrete. The electric mechanical feeding device comprises a quadrangular frustum pyramid shaped hopper, trapezoidal seesaws, breakers, arc-shaped scrapers and variable-frequency motors, wherein the trapezoidal seesaws are connected on the inner walls of the quadrangular frustum pyramid shaped hopper by supports; the breakers are connected on the quadrangular frustum pyramid shaped hopper by bearings; the arc-shaped scrapers are connected with the four corners of the quadrangular frustum pyramid shaped hopper by guide cylinders and are connected with micro axles at the lower end corners of the trapezoidal seesaws by first drive rods; the variable-frequency motors are connected on the outer walls of the quadrangular frustum pyramid shaped hopper by bolts, are connected with small axles on the seesaws by second drive rods and are meshed with gears at the axle ends of the breakers by sector gears. The electric mechanical feeding device has a novel structure, is smooth in feeding, is free from blockage, has stable properties and strong practicability and is firm and durable.
