Technical Field

The utility model relates to an environmental protection equipment field especially relates to a high strength biax breaker.

Background

The double-shaft crusher is a double-shaft shearing type crusher which crushes materials into small-size materials through actions such as shearing, extruding, tearing and the like. The double-shaft crusher well overcomes the limitation that crushers such as a hammer crusher, a jaw crusher and the like can only crush fragile and hard materials such as coal, salt, gypsum, tiles, limestone and the like, and can well crush soft and tough materials such as clothes, branches, wood, films, plastic drums, electronic garbage, medical garbage and the like into small pieces so as to recycle the soft and tough materials.

However, the prior biaxial crusher still cannot completely crush the fiber substances below the needle.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a high strength biax breaker.

The utility model discloses an innovation point lies in rotating through two broken axle differential in opposite directions to produce pulling of certain degree, broken fibrous class material more easily through ratchet form blade to the fibre.

In order to realize the purpose of the utility model, the technical proposal of the utility model is that: the utility model provides a high strength biax breaker, includes the breaker casing, is provided with two parallel arrangement's broken axle in the breaker casing, respectively be equipped with the broken blade of a set of perpendicular to broken axle on the broken axle, broken epaxial drive arrangement that is equipped with drive shaft pivoted, two broken axles are to rotating, there is the difference in the rotational speed of two broken axles, broken blade is the ratchet form. The two crushing shafts oppositely rotate at a different speed, and the fibers are pulled to a certain degree by the ratchet-shaped blade, so that the fiber substances are more easily crushed.

Further, the side wall of the interior of the crusher shell is provided with two rows of cleaning blades, the two rows of cleaning blades are respectively arranged above the two crushing shafts, the surface directions of the two rows of cleaning blades are parallel to the crushing shafts, and the cleaning blades are inserted between the intervals of the crushing blades. Used for cleaning deposits among the crushing blades.

Further, an output shaft of the driving device is connected with a speed reducer, the output shaft of the speed reducer is connected with a crushing shaft through a double-row chain coupling, and the double-row chain coupling is connected through a shearing pin. Through set up the shear pin in double shaft coupling, the shear pin can cut off the connection of reduction gear output shaft and broken axle, prevents that drive arrangement from transshipping, and double shaft coupling can have certain flexible space in radial and axial.

Furthermore, an output shaft of the driving device is connected with the speed reducer, a first flange is arranged on the output shaft of the speed reducer, a second flange in butt joint with the first flange is arranged on the crushing shaft, and the first flange and the second flange are connected through a plurality of shearing pins. The connection between the output shaft of the speed reducer and the crushing shaft can be cut off through the shearing pin, and the driving device is prevented from being overloaded.

Furthermore, a starfish-shaped induction disc is arranged at one end, away from the driving device, of the crushing shaft, a support is arranged on the shell, a rotating speed inductor is arranged on the support, and the rotating speed inductor is located at the starfish-shaped induction disc. The rotating speed reactor is used for sensing the times of the convex thorns on the starlike sensing disc, so as to know whether the crushing shaft is still running.

Furthermore, a shear pin protective cover is arranged outside the shear pin. When the shearing pin is broken, fragments of the shearing pin are scattered in the shearing pin protective cover, so that the safety of operators is protected. Meanwhile, the shear pin is protected from being corroded, oxidized and the like.

The utility model has the advantages that:

1. the utility model discloses in rotate through two crushing shaft differential in opposite directions to produce pulling of certain degree, broken fibre class material more easily through ratchet form blade to the fibre.

2. The utility model discloses in can cut off the connection of reduction gear output shaft and broken axle through the shearing pin, prevent that drive arrangement from transshipping.
