The invention discloses hydraulically-synergistic biomass sawing equipment, and relates to a biomass raw material crushing machine and tool. The hydraulically-synergistic biomass sawing equipment comprises a hydraulic cylinder, a rack and an enclosing cover; the hydraulic cylinder and the rack are arranged in the enclosing cover, and a hydraulic column stretches out of the upper end of the hydraulic cylinder; a saw row assembly, a lifting rod, a left guide rail, a left guide rod, a right guide rail and a right guide rod are arranged in the equipment, the saw row assembly is composed of a lifting chassis, multiple small high-speed motors and multiple disc saw blades, the small high-speed motors are arranged on the lifting chassis, a rotation shaft of each small high-speed motor is provided with the corresponding disc saw blade, and the disc saw blades are horizontally arranged in a straight-line mode; the lower end of the lifting rod is connected with the middle of the lifting chassis, and the upper end of the lifting rod is connected to the upper end of the hydraulic column; when the hydraulically-synergistic biomass sawing equipment works, the saw row assembly is driven by the hydraulic column to do reciprocating lifting motion. According to the hydraulically-synergistic biomass sawing equipment, the hydraulically-synergistic saw row assembly is adopted, biomass raw materials are sawn through the disc saw blades which are arranged in the straight-line mode, the sawing speed is high, and the advantage of being high in crushing efficiency is achieved.
