Zusammenfassung:	The utility model provides a hydraulic auxiliary system and an excavator. The hydraulic auxiliary system comprises an integrated valve body, a main pump, a hydraulic oil tank and a plurality of control devices. A shunting channel and a converging channel are arranged in the integrated valve body; the flow dividing channel comprises a first flow inlet and a plurality of first flow outlets, the first flow inlet is connected to a hydraulic oil outlet of the hydraulic oil tank through the main pump, and each first flow outlet is connected with a hydraulic oil input port of the control device. The flow dividing channel comprises a plurality of second inflow ports and a second outflow port, each second inflow port is connected with a hydraulic oil output port of the control device, and the second outflow port is connected with a hydraulic oil backflow port of the hydraulic oil tank. According to the scheme, hydraulic oil can be supplied to the integrated valve body from the hydraulic oil tank through the main pump
