Embodiment:
Below in conjunction with accompanying drawing enforcement of the present utility model and technical process are described in further detail:
Embodiment 1
Shown in accompanying drawing 1-2, a kind of stalk crasher that is used for industrialization system bio-fuel-oil, comprise: upper box, lower box, main shaft, the air-introduced machine unit, automatic feeder, the feeding electromotor, main motor, bracing frame, rotor assembly, moving knife, the broken tooth plate of coarse crushing tooth plate and fine powder, rotor assembly by jacket casing on main shaft, one end of main shaft is connected with moving knife, an other end of main shaft is connected with main motor by belt, main shaft is connected with lower box with bearing block by bearing, upper box is installed on the lower box, the coarse crushing tooth plate is installed on the lower box, the broken tooth plate of fine powder is installed on the upper box, the feeding electromotor, automatic feeder, main motor and lower box are installed on the bracing frame respectively, automatic feeder is connected with the feeding electromotor, and the air-introduced machine unit is connected with lower box.
