Cone sand making machine and sand making method

Abstract

The invention relates to a cone sand making machine and a sand making method with high efficiency, low energy consumption and high sand making yield. A big bevel gear is sleeved on an eccentric shaft sleeve which is sleeved in an axle hole in the centre of a lower shell through a copper jacket; a main shaft is positioned in the eccentric shaft sleeve through an inner copper sleeve; a spherical seat is positioned on a shell supporting ring of the positioning axle hole in the lower shell; a movable cone is sleeved on the main shaft through a spherical copper bearing bush and pushed by the main shaft to swing; a movable sleeve bushing is sleeved on the conical surface of the movable cone; an anti-wear movable sleeve is sleeved on the conical surface of the movable sleeve bushing; an inserteris sleeved on the main shaft and locked by a locking nut; an upper shell and the lower shell are connected together and three or more adjusting oil cylinders are arranged between the outer turned edges of the upper and lower shells; the inner wall of the upper shell is provided with annular spiral sawteeth which are engaged with those on the outer wall of an adjusting screw sleeve; and the adjusting screw sleeve has a double-trumpet structure, the lower trumpet-shaped wall of the adjusting screw sleeve is connected with an anti-wear fixed sleeve through a fixed sleeve bushing, and the upper trumpet-shaped wall of the adjusting screw sleeve is used for supporting a hopper assembly.
