Overturning hopper and control method thereof

Abstract

The invention discloses an overturning hopper. The overturning hopper comprises a hopper body, a hopper revolving support and an overturning mechanism, wherein the overturning mechanism comprises a link and a crank, one end of the link is hinged onto the hopper body, the other end of the link is hinged with the crank, and the other end of the crank is hinged onto a crank revolving support through a crank rotary shaft; and the receiving point and the unloading point of the hopper are both arranged at or close to the dead point of the overturning mechanism through optimizing the starting point and the ending point of the crank, so that the impacted force working condition of speed reducer equipment is optimized during the loading and the unloading of the overturning hopper. According to the mechanism, the centre-of-gravity position of the hopper body and the centre-of-gravity position of the hopper after the loading are further optimized, so that the centre of gravity of the hopper body is located between the revolving hinge point of the hopper and the supporting hinge point of the link and close to the revolving hinge point of the hopper; and requirements on the output torque of a speed reducer are greatly lowered by virtue of the force amplification effect of the link, so that the weight of the speed reducer equipment and the power of a tilting motor are greatly reduced, and the motor power and the energy consumption of the system are saved.

Description

technical field [0001] The invention belongs to the field of material transportation or handling, and in particular relates to a tipping hopper and a control method thereof. Background technique [0002] Tilting hopper is a common loading and unloading mechanical equipment, and its tilting mechanism determines the working quality of the tilting hopper to a large extent. [0003] There are many mechanical design methods to realize the charging and tipping functions of the tilting hopper, including cylinder hydraulic drive, electro-hydraulic push rod, electric push rod drive, direct drive of reducer, etc., each of which has advantages and disadvantages. For example, the electro-hydraulic push rod drive has the advantages of simple equipment and light weight, but the thrust is small and the reliability is slightly poor in use. The hydraulic drive of the oil cylinder needs to be equipped with a hydraulic system. The system (including various valves, motors, sensors, etc.) and c...
