Rotary hopper device

The rotary hopper device solves the problems that after asphalt materials are cooled, a gate is difficult to open, and the feeding mode is not suitable for a transition section asphalt material paving device, the rotary hopper device is provided with two sets of swing mechanisms, one set of W swing mechanism is used for rotating a hopper to different material receiving or discharging positions, and the other set of H swing mechanism can enable the hopper to rotate around the geometric center of the rotary hopper device. A hopper opening receives materials upwards and discharges materials downwards. When the hopper receives materials, the W slewing mechanism drives the hopper to rotate to a material receiving position; and during discharging, the W slewing mechanism drives the hopper to rotate to a discharging position. During material receiving, the H swing mechanism rotates the hopper by 0 degree to enable the opening of the hopper to face upwards, and during discharging, the H swing mechanism rotates the ho
