The invention discloses a
cutting device for log
machining. The device comprises a box body, a first
conveyor belt and a second
conveyor belt, wherein a second electric push rod is arranged on the inner wall of the top of the box body, a fixing plate is connected to the outer wall of one end of the second electric push rod, a protective shell is arranged on the outer wall of one side of the fixingplate, a motor is arranged on the inner wall of one side of the protective shell, a
cutting wheel is arranged on the outer wall of one end of a motor output shaft, a
liquid storage box is arranged onthe outer wall of the top of the box body, a connecting
pipe is inserted into the outer wall of one side of the
liquid storage box, one end of the connecting
pipe extends into the box body, and an atomizing
nozzle is in threaded connection with the outer wall of one end of the connecting
pipe. According to the device, when the
cutting wheel cuts a log, a first electric push rod and a third electric push rod are started, the first electric push rod and the third electric push rod drive a fixing ring to move downwards, a wood body can be effectively fixed, the cutting work stability is guaranteed, and the cutting efficiency of the device is improved.
