The invention discloses a scrap iron transferring device applied to a machining workshop, comprising a feeding mechanism, an air blowing mechanism, a compressing mechanism, a cleaning mechanism and adrying mechanism, wherein the feeding mechanism is provided with a pair of externally-tangent rotating drawing wheels for conveying scrap iron; air jet nozzles are arranged above the scrap iron, the air jet nozzles spray air flow to blow off scrap cutting liquid and dust on the scrap iron, and a filter tank for collecting the scrap cutting liquid is arranged below the scrap iron; the compressing mechanism is provided with a pressing plate with a linear reciprocating motion freedom degree, wherein the pressing plate presses the scrap iron to reduce the size of the scrap iron; the cleaning mechanism is provided with a cleaning tank for cleaning the scrap iron; the drying mechanism is used for drying the scrap iron; and after the scrap iron passes through the feeding mechanism, the scrap ironsequentially passes through the air blowing mechanism, the compressing mechanism, the cleaning mechanism and the drying mechanism. The device has the advantage of good overall automation degree, andhigh hierarchical collection and cleaning efficiency, the scrap iron and the scrap cutting liquid can be collected and recycled, and the recycling efficiency is high.
