US 10,858,179 B2 · Tipping hopper and control method thereof

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.

Dependent claims

A tipping hopper, comprising:

a hopper body and hopper rotating supports, wherein the tipping hopper further comprises a tipping mechanism hinged at a rear of the hopper body;
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 wherein the connecting rod has a bend located between ends of the connecting rod;
an other end of the crank is hinged on a crank rotating support through a crank rotating shaft;
a center of gravity of the hopper body is located between a hopper rotating hinge point and a connecting rod support hinge point;
the hopper rotating hinge point is a hinge point between the hopper body and the hopper rotating supports;
wherein the connecting rod support hinge point is a hinge point between the connecting rod and the hopper body;
and
a blocking material plate which is fixed in place relative to movements the hopper, such that the material blocking plate is in the same position when the hopper is in either a material receiving position to prevent material from exiting the hopper or in a discharging position to allow material to exit the hopper.
