Abstract
A tipping hopper includes a hopper body, hopper rotating supports and a tipping mechanism. The tipping mechanism comprises a connecting rod and a crank. One end of the connecting rod is hinged on the hopper body, and the other end is hinged with one end of the crank; and the other end of the crank is hinged on a crank rotating support through a crank rotating shaft. By optimizing a crank starting point and a crank end point, ensure hopper's position of receiving and discharging material is arranged at or near a dead point of the tipping mechanism so that the working condition of an impact force borne by a speed reducer device is optimized when the tipping hopper is charged and discharged. The mechanism also optimizes the position of the center of gravity of the hopper body and the position of the center of gravity of a charged hopper, so that the center of gravity of the hopper body is located between a hopper rotating hinge point and the connecting rod support hinge point near the hopper rotating hinge point. A force amplification effect of the connecting rod is used to greatly reduce the requirement for the output moment of the speed reducer, thereby greatly reducing the weight of the speed reducer device and the power of a tipping motor and saving motor power and energy consumption of a hoisting system.
