The chipping (crushing) machine is unit for reducing of wood which is, as a rule, used for cleaning of roadsides of roads, the power transmission line, gardens and park services, processing of unconditioned wood on wood processing productions.
Disk chipping machines are the simplest type of machines which are intended for crushing of branches, gorbylya, wood of small diameters (as a rule to 180 mm). Attachment — unary steel disk with a diameter of 800 mm. On knife wheel in knife pockets 2 cutting knives are established, and in the body 1 counterblade is established. The raw materials move in the bunker the worker manually and by means of hydraulic giving move in working zone. The hydraulic system is two rotating rollers put in action by hydromotors, at the same time the machine is equipped with own hydraulic system. The drive of machines, with own hydraulic system, is carried out from shaft of knife wheel through wedge-belt transfer.
Machines generally with the drive from tractor or with the drive from the electric motor are manufactured. Machines with the drive from tractor are installed on three-point hinge plate of tractor, at the same time the drive of disk is carried out from tractor VOM through Cardan. Machines with the drive from electric motor are installed permanently, at the same time the drive of disk is carried out through wedge-belt transfer.
