The specific embodiment

Below in conjunction with embodiment, the utility model is further described, but protection domain of the present utility model not only is confined to embodiment.

As depicted in figs. 1 and 2, a kind of shredder comprises frame 15, material feeding box 6, hydraulic means 8, pusher 4, conveying mechanism 7, hydraulic arm 9 and columniform rotor 1.Material feeding box 6 is arranged on the upper end of frame 15, and hydraulic means 8 is arranged on the inside of frame 15.Material feeding box 6 is used for putting into material, and material adds from the top of material feeding box 6, and the power of hydraulic arm 9 mainly provides by hydraulic means 8.One side of material feeding box 6 is provided with access door 5, is used for the equipment installation and maintenance.

Rotor 1 is positioned at the below of material feeding box 6 inside, the upper end of pusher 4 is fixed on material feeding box 6, rotate as the center of circle take the upper end of pusher 4 lower end of pusher 4, the two ends of hydraulic arm 9 are separately fixed on the bottom and pusher 4 of material feeding box 6, the stretching motion of hydraulic arm 9 has driven the swing of pusher 4, and then the direction of material toward rotor 1 can be pushed.
