The invention provides a paper mulberry ensilage direct harvesting baler which comprises a cutting table assembly, a secondary rubbing conveying mechanism, a cab assembly, a fan assembly, a baler assembly and a crawler-type walking assembly. Paper mulberries are harvested through the cutting table assembly, fed through a feeding wheel assembly, and extruded through a bridging assembly to enter the fan assembly; paper mulberry stems are subjected to primary cutting of a cutter I of the fan assembly and then finely cut through a cutter II, the paper mulberry stems are rubbed by fan blades and then fed into the secondary rubbing conveying mechanism through a fan, the paper mulberry stems are rubbed by a rubbing box in the secondary rubbing conveying mechanism, then a feed additive is sprayed to the paper mulberry stems in a spraying box, the paper mulberry stems are pushed to a conveying belt, and ensilage feed is conveyed to the baler assembly through the conveying belt for baling. The paper mulberry ensilage direct harvesting baler is compact and light in structure and facilitates work, and integrated work of harvesting, conveying, cutting, rubbing and balking of the paper mulberries is achieved. The blank of paper mulberry integrated harvesting work machines at home and abroad is filled up.
