[0038] Working principle: Startup preparation, connect the wood chipper to the tractor through the three-point hitch system. The tractor provides power and transmits the power to the input end of the gearbox 9 through the PTO shaft. After the power is adjusted to the appropriate speed and torque by the gearbox 9, the driving wheel 17 is driven to rotate from the output end of the gearbox. The driving wheel 17 drives the driven wheel 16 to rotate through the belt, and then the cutter head shaft 13 starts to rotate. When the cutter head shaft 13 rotates, the moving knives 15 fixed on it also rotate at high speed. The wood to be broken enters the interior of the wood chipper from the feed hopper 11 and is cut into pieces by the cooperation of the rotating moving knives 15 and the fixed knives 14. The pieces are discharged from the bottom of the lower housing 3 of the cutter head and enter the discharge hopper 2. The broken wood pieces are discharged from the discharge hopper 2. The discharge port adjusting plate 1 can adjust the opening and closing angle manually or mechanically to control the discharge speed and the size of the broken wood. Through the lifting chain 4 and the lower suspension pin 6 and the upper suspension pin 8 on the three-point hitch 7, the wood chipper can be easily moved from one place to another.
