Surface profile detection apparatus of burden and operation method

A surface profile detection apparatus of a burden, the surface profile detection apparatus being installed to an opening of a container of various facilities and being configured to detect a surface profile of the burden by transmitting, through the opening, a detection wave toward a surface of the burden supplied and deposited in the container and receiving the detection wave reflected on the surface of the burden, the surface profile detection apparatus comprising:

• a transmission and reception means for transmitting and receiving the detection wave;
• an antenna connected to the transmission and reception means and configured to transmit and receive the detection wave;
• a circumferential scanning means for scanning the detection wave in a circumferential direction of the container;
• and
• a diametrical scanning means for scanning the detection wave in a diametrical direction of the container by tilting an angle variable reflection plate,
• wherein the diametrical scanning means tilts the angle variable reflection plate by means of a swing mechanism and a spline driven by a drive source for driving the circumferential scanning means, and
• wherein the circumferential scanning means and the diametrical scanning means are caused to cooperate with each other, thereby scanning the detection wave in the diametrical direction of the container while scanning the detection wave in the circumferential direction of the container.
