Taishan County, Guangdong Agricultural Machinery Plant No. 2, in order to meet the needs of production and development, to solve the problem of reuse of old sand after casting sand, sand in 1973 learning advanced experience in fraternal units, summarizes the characteristics of various types of sieve sand machine basis On a self-made swing shock sieve machine. After put into production, in good condition, welcomed by the workers. Three more were later made and were widely used in the workshop, greatly improving the working conditions of the workers. This machine uses a 1 kilowatt electric motor as the motive force, by the triangular pulley decelerates first (the electrical machinery pulley φ60 ~ 80 millimeters, the main axle
