Device for grinding chopping residues

The utility model relates to forestry， in particular to equipment for grinding chopping residues. A device for grinding chopping residues comprises a prismoid-shaped loading cartridge case， a chip chipper， a chopper with rectangular blades and protrusions， a casing， a belt drive， a drive shaft， a feed mechanism consisting of a finger-type feed device and feed rollers， a lifting device frame， a hydraulic cylinder， a pipeline， oil tank， cutting discs， console， pulley system， reduction gear， shaft， V-belt drive， characterized in that on the surface of the blades with rectangular protrusions Fins are installed， and the casing has openings for creating ascending air currents. The design of the device for grinding chopping residues allows to increase the efficiency of the process of ejecting chips through the chips by creating upward air flows in its casing with the possibility of mechanical regrinding of chips.
