The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.

As depicted in figs. 1 and 2, the driving principle of the drum chipper that provides among the figure is:

Low-voltage driving motor 130,230 drives small belt pulley 120,220 by shaft coupling 121,221 and rotates, belt 122,222 be enclosed within respectively small belt pulley 120,220 and big belt pulley 100,200 on, drive motors 130,230 rotates, drive main shaft 50 and rotate by shaft coupling 121,221, small belt pulley 120,220, belt 122,222, big belt pulley 100,200, and rotate from two ends driven in synchronism cutter drum 60.
