UNLOADING DEVICE FOR CONVEYOR-TYPE SINTERING AND ROASTING MACHINES Russian patent published in 1997 - IPC

Abstract RU 2086870 C1

FIELD: sintering and roasting machines. SUBSTANCE: clearance between trucks is selected depending on cargo pressure of unloading part; removal of unloading device is effected hydraulically. Device comprises sprockets mounted in movable frame and mechanism for removal of frame with hydraulic cylinders of different diameters connected in series. To ensure similar position of rods of both hydraulic cylinders, hydraulic line connecting the rod chamber of cylinder of larger diameter with piston chamber of cylinder of less diameter is additionally connected with rod chamber of cylinder of less diameter through check valve; besides, hydraulically-controlled two-valve distributor is built in it; control chamber of distributor is connected with the same rod chamber of cylinder of less diameter. EFFECT: enhanced reliability. 2 dwg
