The invention discloses a novel rapid building block core filling device and belongs to the technical field of building block processing. The filling can be applied to other fields after being subjected to simple modification, for solving the problems that the conventional manual building block core filling efficiency is low, the operating environment is poor, the time and labor are consumed, theproduction cost is increased, and continuous and high-efficiency production is not facilitated. The novel rapid building block core filling device disclosed by the invention comprises a rack, a powerdevice, a transfer device, a rapid filling device, a cleaning device and a detection device, and is characterized in that a transport device on the rack drives a mold to move forwards by virtue of chain drive, and the rapid filling device, the high-pressure cleaning device and the detection device are arranged on the rack. The novel rapid building block core filling device disclosed by the invention is simple in structure, ingenious in design, low in cost and high in reliability, full-automatic, high-efficiency and high-quality filling is realized, and the core filling efficiency in the production process is increased. Meanwhile, the labor intensity of the staff is reduced, and the operating environment quality of the staff is improved.
