Abstract
The present invention relates to a fluted roller structure of a double roller crusher, which comprises a roller shaft, a roller and a blade, wherein a dovetail groove is arranged on the surface of the roller, and the blade is closely clamped and arranged in the dovetail groove of the roller by a wedge block. The shape of the wedge block is matched with that of the dovetail groove of the roller, and the blade is in a floating telescopic state in the dovetail groove. The structure can protect the blade arranged on the roller from being broken in operation processes by hard objects, such as mixed metal, etc.
Description
Technical field
The present invention relates to a kind of double-roll crusher, relate in particular to a kind of discaling roll structure of double-roll crusher.
Background technology
Existing double-roll crusher adopts two smooth rolls or double teeth roller structure, is applicable to broken medium-hard material.Adopt the kibbler roll of discaling roll structure, can adopt various method, process difform tooth or groove,, improve the ratio of reduction to increase shearing-crushing effect to material on the surface of roller.This double-geared roller crusher also is not suitable for broken clay class material.Because the moisture of material is extruded in shattering process, material is adhered between cog or the groove, and be difficult for being eliminated, influence normally carrying out of crushing operation.For this reason, can adopt the mode that blade is installed on roller to solve the existing problem of the broken clay class material of double-roll crusher.But blade enters crusher chamber if be fixedly mounted on the roller when hard thing is mingled in the material, and blade is run into hard thing in the process of rotation at a high speed easily broken.
Summary of the invention
The technical problem that the present invention solves provides a kind of discaling roll structure of double-roll crusher, and it can prevent that the blade of installing on the roller from being smashed by metal object.
The discaling roll structure of double-roll crusher of the present invention comprises roll shaft, roller and blade, and wherein, the surface of described roller offers dovetail groove, and blade blocks in the dovetail groove that is installed in roller with voussoir; The dovetail groove shape of the shape of this voussoir and described roller matches, and makes blade be in unsteady Telescoping in dovetail groove, described voussoir voussoir bolting.
Adopt after the said structure, the dovetail groove of voussoir and roller is combined closely, and blade is contained in the dovetail groove of roller, and during operate as normal, roller drives blade and rotates at a high speed, because action of centrifugal force, blade throws away material is carried out cutting operation.When running into hard thing, because blade is in telescopic quick condition, but in the blade part indentation dovetail groove, it is broken effectively to protect blade to prevent.
Description of drawings
Fig. 1 is the discaling roll structural representation of double-roll crusher of the present invention;
Fig. 2 is that the A of Fig. 1 is to view.
The specific embodiment
Referring to Fig. 1, the discaling roll structure of double-roll crusher of the present invention comprises roll shaft, roller and blade.The surface of described roller 1 offers a plurality of dovetail grooves 2, and evenly distributes at circumferential surface.Voussoir 4 blocks blade 3 in the dovetail groove 2 that is installed in roller 1, and the inclined-plane of voussoir 4 and blade dress voussoir Fang Chu inclined-plane match, and described voussoir 4 usefulness voussoir bolts 5 are fixing.After voussoir bolt 5 and roller assembling are fastening, make blade 3 in dovetail groove 2, be in unsteady Telescoping, but blade 3 touch in the hard thing indentation dovetail groove 2 like this, avoids blade broken when work.
For the person of ordinary skill of the art, under the prerequisite that does not break away from the principle of the invention, can also make some modification and improvement, these also should be considered as protection scope of the present invention.
Claims (2)
1. the discaling roll structure of a double-roll crusher comprises roll shaft, roller and blade, it is characterized in that: the surface of described roller is provided with dovetail groove, and blade blocks in the dovetail groove that is installed in roller with voussoir; The dovetail groove shape of the shape of this voussoir and described roller matches, and makes blade be in unsteady Telescoping in dovetail groove, and described voussoir is fixed together with the voussoir bolt.
2. the discaling roll structure of double-roll crusher as claimed in claim 1, it is characterized in that: described dovetail groove evenly distributes at the roller circumferential surface.
