Furthermore, the rotary cutting crushing cutter group adopts a rotary cutting cutter structure, and a cutter head of the rotary cutting crushing cutter group adopts an assembly structure so as to replace a worn cutter head.

Furthermore, the feeding bin adopts a cone hopper structure with a blanking angle of more than or equal to 60 degrees, so that the soil can fall smoothly.

Further, the surface of roller pair is equipped with bellied hemispherical tooth, can play and impress cubic soil the roller to the effect between to, prevents that bold soil from skidding on the roller, can also the broken stone of parcel in soil simultaneously. The scraping device is also provided with a tooth groove which is convenient for the hemispherical teeth to pass through.

Further, the roller is to last setting up clearance adjustment structure and rotational speed regulation structure, can control blocky soil and press into flaky thickness through clearance adjustment structure adjustment roller to the clearance between, can conveniently control soil feeding volume through the regulation of roller rotational speed.

Furthermore, add and to line tetrafluoroethylene board in the feed bin, because tetrafluoroethylene board surface friction coefficient is low, make the soil that adds in the feed bin can be very smooth fall into the roller is internal from this.

Further, the cutter head of the rotary-cut crushing cutter set can be designed into a pendulum type, and a shell of the rotary-cut crushing cutter set is lined with a tetrafluoroethylene plate.

The utility model discloses during the use, from the cubic soil that adds the feed bin and fall, rolled into the slice under the effect that the roller is right, the roller is convenient for impress cubic soil to the roller of last design between to, prevents that bold soil from skidding between the roller is right, also can be broken with the stone of parcel in soil the inside. The roller is to the scraper of bottom in time clear up the soil of gluing on the roller, and is equipped with the tooth's socket on the scraper, and the epaxial hemispherical tooth of roller of being convenient for passes through the scraper. The soil rolled into sheets by the roller falls onto the rotary cutting and crushing cutter set rotating at high speed, and the sheets are cut into fine pieces and then fall into the material collecting device under the action of the rotary cutting and crushing cutter set. Because the rotary cutting crushing cutter set rotates at high speed, the soil can not be adhered. Aiming at the soils with different viscosities, the purpose of crushing the soil with high efficiency and energy saving can be achieved by adjusting the rotating speed of the power executing element.

Compared with the prior art, the utility model has the advantages of:

the utility model discloses be used for the breakage of soil specially, it adapts to soil wide range, can adapt to the soil breakage of higher viscidity or moisture content very much, and broken high efficiency energy-conservation.
