Crushing tooth 25 includes integrally formed toothholder and denticle, and toothholder includes arc-shaped top surface 251 and mounting portion 256, circle Arc top surface 251 and roll body 22 are coaxially arranged, and denticle is arranged on arc-shaped top surface, and mounting portion 256 is up-small and down-big structure, Denticle has bottom surface, top surface 252, two cutting faces 253, two sides 254 and the back side 255, and bottom surface connects the arc-shaped top surface of toothholder 251, top surface 252 and bottom surface are positioned opposite, two cutting faces 253, two sides 254 and the setting of the back side 255 bottom surface 252 and top surface it Between, two cutting faces 253, which are located on front side of denticle, to form an angle, and two sides 254 are oppositely arranged in parallel in denticle two sides, the back side 255 are in tilted layout on rear side of denticle.

The vertex of two cutting faces, 254 intersecting lens to line and two cutting faces 254 between 21 center of roll body intersecting lens it Between angle be 11 degree, round-corner transition between two cutting faces 254, the angle between two cutting faces 254 is 90 degree.

First roll body 22A is provided with up-small and down-big mounting groove 27, and mounting groove 27 is adapted with the mounting portion 256 of toothholder, One cell wall of mounting groove 27 is made of latch segment 26, which is detachably arranged at the first roll body 22A by bolt 261 On, latch segment 26 is sphenoid.

25 liang of cutting faces 254 of crushing tooth constitute wedge structure, are rolled by the wedge structure and twist into and be crushed bulk raw 7, when 25 serious wear of crushing tooth, detachable latch segment 26 was replaced；Compression tooth 23 is welded on the first roll body 22A, for pressing Contracting particle size after cracking fritter raw material；Cutting gear ring 24 is welded on roll body 22, cuts the zigzag bumps on gear ring 24 for inducing Raw material rotation, and raw material is cut with crushing tooth 25 and compression 23 collective effect of tooth, referring in particular to shown in Fig. 9, breaker roll 2 works wink Between, crushing tooth 25 and compression 23 alternating action of tooth.

The side wall opposite with breaker roll 2 of cabinet 1 is provided with liner plate 12, is provided on liner plate 12 along the length side of breaker roll 2 To the casting lug thereon 121 of arrangement, the groove passed through for crushing tooth 25 is constituted between adjacent two casting lug thereon 121,12 device of liner plate uses Potassium steel wear-resistant liner.

Hydraulic station 31 is provided with hydraulic pump, hydraulic pump motor 311, pressure switch, hydraulic directional valve, hydraulic pump when work Motor 311 starts, hydraulic pump works, so that two hydraulic motors 32 be driven to slowly run, hydraulic motor 32 passes through internal spline 322 Breaker roll 2, the relatively independent rotation of two breaker roll 2 are transmitted torque to external splines 222.

Raw material is fallen on breaker roll 2 from elevating hopper 11, and the rotation of breaker roll 2 squeezes raw material toward between two breaker rolls 2, fritter The compressed effect of tooth 23 of raw material is broken, and bulk raw is acted on by 25 local compression of crushing tooth and is crushed.Broken material warp Gap between two breaker rolls 2 is fallen.When raw material is really up to the mark or size super large, can not an attrition crushing when, two breaker rolls 2 Active force increases, and hydraulic pressure is made to increase to set pressure limit, and pressure switch movement promotes hydraulic directional valve to change To, hydraulic motor 32 inverts, so that breaker roll 2 be made to rotate backward, the active force to breaker roll 2 laid down, avoids active force excessive, Beyond the 2 bending deformation limit of breaker roll.Active force is laid down in reversion, and hydraulic pressure restores normal, hydraulic directional valve movement, hydraulic horse It is turned to up to 32 and restores normal direction of rotation, repeatedly.

The requirement that the spacing between two breaker rolls 2 adapts to different output is adjusted by eccentric hub, due to 2 low speed rotation of breaker roll Dynamic, the winding inertia of reinforcing bar 6 in concrete is smaller, often due to being not easy to be wrapped in brokenly by the impact of material in rotary course On broken roller 2, when there is reinforcing bar wrapping phenomena, generally it is wrapped on cutting gear ring 24, as shown in Figure 10, passes through breaker roll 2 Positive and negative rotation continues to rotate, can at leisure separate reinforcing bar 6 when raw material 7 is withstood in 6 connector one end of reinforcing bar with breaker roll 2 Come.Meanwhile two the distance between breaker roll 2 it is bigger, be more conducive to falling off for reinforcing bar 6.It is convenient that reinforcing bar 6 is removed, and greatly reduces The labor intensity manually removed.

The above, the only preferred embodiment of the utility model, therefore the utility model implementation cannot be limited with this Range should still belong to this that is, according to equivalent changes and modifications made by present utility model application the scope of the patents and description In the range of utility model patent is covered.
