For addressing the above problem, take following technical scheme:

Refuse grinder of the present invention comprises base, and casing is arranged on the base, and two main shafts are arranged in the casing.Two main shafts parallel, and they are on the same level, and their two ends are rotatable shape respectively and are installed on two relative sidewalls of casing, and their end stretches out outside casing and links to each other with a driving mechanism respectively.All be fixed with hobboing cutter on two main shafts.Be characterized in that the blade row frame is arranged in the casing, the shape of this blade row frame identical with the shape of cabinets cavity and and casing between be connected mutually.The blade row frame the horizontal groove of two row vertically arranged, two row are staggered layout between horizontal groove, thereby make that part of blade row frame between per two horizontal grooves form blade row.Described two main shafts pass through the horizontal groove of two row respectively, on that section main shaft in each horizontal groove a described hobboing cutter are arranged all.

Described hobboing cutter contains axle sleeve, and interior cutter head and outer cutter head are arranged on the axle sleeve.Wherein: interior cutter head contains two interior cutters tooth, and this two interior cutter tooth is all towards inner bending.Outer cutter head is a crescent, forms as one with axle sleeve in the middle of its concave surface, and leaves spacing between its two and corresponding interior cutter tooth, thereby make its concave surface two form two-way outer cutter tooth.

Take such scheme, have the following advantages:

By such scheme as can be seen owing in the casing blade row frame is arranged, this blade row frame the horizontal groove of two row vertically arranged, two row are staggered layout between horizontal groove, thereby make that part of blade row frame between per two horizontal grooves form blade row.Described two main shafts pass through the horizontal groove of two row respectively, on that section main shaft in each horizontal groove a described hobboing cutter are arranged all.During work, by the rotation hobboing cutter and fixedly the relative motion between the blade row realize fragmentation to rubbish, become the shearing that is cut between traditional hobboing cutter and hobboing cutter between hobboing cutter and blade row, avoided bulk rubbish to pass through from the gap between two hobboing cutters, the rubbish granularity that feasible fragmentation goes out is less, even, thereby has improved crushing effect greatly.Again owing to adopt this structure, two main shafts and on the hobboing cutter independent operation, they both can be with speed running, differential movement, but also independent operation, even main shaft and on hobboing cutter be obstructed and can not rotate, can not influence yet another root main shaft and on hobboing cutter running, need two main shafts to turn round simultaneously with traditional refuse grinder and compare, can reduce power consumption, save the energy, reduce production costs.In addition, be the monoblock type hobboing cutter owing on two main shafts hobboing cutter and hobboing cutter only being arranged, compare with traditional refuse grinder hobboing cutter of forming by hob plate and a plurality of cutter heads, need not change cutter head, repair than being easier to.On the other hand, because described hobboing cutter contains axle sleeve, interior cutter head and outer cutter head are arranged on the axle sleeve, should with outer cutter head two-way interior cutter tooth and two-way outer cutter tooth be arranged respectively by interior cutter head, can realize two-way fragmentation, only can realize that with the hobboing cutter of traditional refuse grinder unidirectional fragmentation compares, can prolong its service life greatly.
