The invention discloses a stack-up sericulture device. The stack-up sericulture device comprises a feeding tray frame, a bracket, a first connecting plate, a second connecting plate, a telescopic rod, multiple pairs of connecting bars and multiple pairs of transverse bars, wherein the feeding tray frame comprises four first upright columns and four first crossbeams; the bracket is located at the left side of the feeding tray frame, is rotatably connected with the feeding tray frame and comprises four second upright columns, four second crossbeams and four third crossbeams; the first connecting plate and the second connecting plate are separately arranged on two opposite side faces of the feeding tray frame and the bracket; the telescopic rod is horizontally arranged between the first connecting plate and the second connecting plate and is vertical to the first connecting plate; the multiple pairs of connecting bars are arranged among the four first upright columns from top to bottom; the multiple pairs of transverse bars are arranged between the second crossbeams and the third crossbeams from top to bottom. According to the stack-up sericulture device, procedures of rapid, timesaving, laborsaving and silkworm-direct-contact-avoided bed cleaning and mulberry leaf replacing can be achieved, the sericulture effect is improved, and thus, the stack-up sericulture device has a relatively high practical value.
