The invention relates to an automatic soil filling device and method for a large
geotechnical engineering model test, and belongs to the technical field of
geotechnical engineering model tests. Comprising a
wireless control system, a spiral soil moving device, a soil containing device, a
wireless data transmission type electronic hoist scale, a
wireless crown block transportation device and a model box. The spiral earth moving device is composed of a
spiral blade, a conveying
pipe and a wireless rotary
brake. The conveying
pipe is provided with an input port and an output port, and the
spiral blade is arranged in the input port; the soil containing device comprises a cylindrical funnel, the upper portion of the cylindrical funnel is open, the periphery is sealed, two baffles are arranged at the bottom, and armatures are arranged on the inner sides of the two baffles. The wireless crown block transportation device comprises a lifting
rope, a circular ring is connected below the lifting
rope, the circular ring is connected with a
wireless data transmission type electronic hoist scale, and a hook is arranged at the bottom of the
wireless data transmission type electronic hoist scale; and the
wireless control system wirelessly and remotely controls the spiral soil moving device, the soil containing device, the
wireless data transmission type electronic hoist scale and the wireless crown block transportation device through an antenna.
