Patent ID: 7648091

Claim:
A movable wood crushing machine for producing crushed wood chips by crushing charged wood, comprising: a vehicle body provided with a travel device for traveling; a rotary crushing device provided at a first end of the vehicle body in a traveling direction for crushing the wood into the wood chips; a tub-type feeder having a rotary tub rotatably provided on the rotary crushing device with a charging opening for charging wood to be crushed formed on an upper part thereof, the feeder being arranged such that the charging opening is open toward the first end of the vehicle body in the traveling direction and obliquely to the traveling direction in a planar view; a conveyer extending from a position under the rotary crushing device toward a second end of the vehicle body in the traveling direction, opposite the first end, for transferring and discharging the wood chips crushed by the rotary crushing device away from the vehicle body; and a drive unit provided between the rotary crushing device and the conveyer for driving drive sources for the travel device, the rotary crushing device, the tub-type feeder, and the conveyer; wherein the rotary crushing device is provided at a position adjacent to the drive unit; and wherein the tub-type feeder has a scattering prevention cover provided at a position corresponding to the position of the rotary crushing device and which only partially covers the charging opening, and wherein the scattering prevention cover is arranged relative to the charging opening when the rotary crushing device crushes the wood into wood chips and the conveyer transfers the wood chips crushed by the rotary crushing device away from the vehicle body such that a part of the charging opening not covered by the scattering prevention cover opens in a direction opposite to an extending and crushed wood chip transfer and discharge direction of the conveyer and any wood chips that are discharged from the uncovered part of the charging opening do not fall onto the conveyer.
