Abstract
The utility model discloses a crusher toothed roller capable of automatically avoiding hard foreign matters, which comprises a toothed roller crusher and two toothed roller shafts, wherein at least two bearing bases of one toothed roller shaft are installed on a hydraulic cylinder respectively from middle portions, and oil pipes are respectively led out from each hydraulic cylinder and are together connected on an oil feed and return device. The crusher toothed roller has the advantages of automatically avoiding hard foreign matters, resetting accurately and stably, guaranteeing crushing quality and prolonging the service life of toothed rollers.
Description
Technical field:
The utility model relates to fragmentation, particularly a kind of disintegrating machine discaling roll of dodging hard foreign matter automatically that uses on the toothed roll crusher that is applicable to.
Background technology:
When present toothed roll crusher, two discaling rolls are done relative running, fix because of the bearing block of a discaling roll, the bearing block of another discaling roll can move horizontally, and resets by the spring on the bearing block.Though this structure is avoided the damage of hard foreign matter to discaling roll and tooth plate, but because of the long-time pressurized of spring easily produces fatigue deformation and fracture, cause the reseat pressure instability, influence the uniformity of particle size after cracking, change relatively difficulty of accessory simultaneously, influence production efficiency and quality.
Summary of the invention:
The purpose of this utility model provide a kind of reseat pressure accurately, stable, fragmentation quality is good, production efficiency is high, can dodge the disintegrating machine discaling roll of hard foreign matter automatically.
Technical solution of the present utility model is: it comprises a toothed roll crusher, it is characterized in that: two bearing blocks of at least one discaling roll axle are installed on the hydraulic cylinder from the centre respectively in two discaling roll axles, lead to oil pipe on each hydraulic cylinder respectively and are connected jointly on the repairing oil return apparatus.The higher foreign matter of hardness is arranged through out-of-date between two discaling rolls, movably discaling roll is passed to hydraulic cylinder with pressure after stressed, regulates the oil pressure of each hydraulic cylinder automatically by the repairing oil return apparatus, allows hard foreign matter pass through smoothly, automatically adjust the pressure of each oil cylinder then again, discaling roll is automatically reset.Have dodge hard foreign matter automatically, reset accurately, stable, guarantee fragmentation quality, prolong the discaling roll advantage in service life.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
Describe embodiment in conjunction with the accompanying drawings in detail.The utility model is improvements over the prior art, it is in two discaling roll axles 2 of a toothed roll crusher 1, two bearing blocks 3 with any one discaling roll axle, be installed on two hydraulic cylinders 4 from middle symmetry respectively, lead to oil pipe 6 on each hydraulic cylinder respectively and be connected jointly on the repairing oil return apparatus 5.During work, through out-of-date, the discaling roll that is installed on the hydraulic cylinder passed through by to be allowed hard thing by automatic jack-up as hard thing, avoids hard thing top to hinder discaling roll, and hard thing is regulated oil pressure by the back automatically by the repairing oil return apparatus resets discaling roll.The utility model also can be installed in the bearing block of two discaling roll axles on two groups of hydraulic cylinders, reaches same effect.
