PURPOSE:To replace the cutter blade an clean the head of the titled device simply by a method wherein a hydraulic motor for driving a rotary cutting unit is provided and the cutter holder of the rotary cutting unit is coupled to the rotor of the hydraulic motor directly. CONSTITUTION:The cutter holder 21 is coupled directly to the rotor 11 of the hydraulic motor 10 through screwing means and receives the transmission of power through fluid. Accordingly, the hydraulic pump 27 as the driving source of the hydraulic motor 10 can be set at a place far from the resin pelletizing device while respective lines 26, 28 between the hydraulic pump 27 and the hydraulic motor 10 can be connected detachably through fluid supplying pipes such as flexible hoses or the like. As a result, troublesome work for removing the motor is not necessary upon replacing the cutter blade 24 or cleaning the head 2 of the cutting unit, therefore, maintenance may be effected in a short period of time by only removing the necessary minimum parts of the device. |
