Description
Technical field
The invention belongs to mechanical equipment technical fields, more particularly to a kind of crusher in adjustable breaker roll gap.
Background technique
In order to guarantee the discharging-material size of crusher and the work of crusher normal reliable, it is respectively provided on crusher mutually solely
Roll gap adjustment device and overload yielding device vertical, work respectively.Roll gap adjustment regulating device, effect are to adjust fixed be crushed
Gap between roller and dynamic roller meets the size requirement of crusher discharging-material size.Crusher overloads yielding device, and effect is to work as
When crusher overloads, so that dynamic roller retreats, reduces crusher load, realize the overload protection of crusher.
Artificial or screw mechanism is generallyd use at present to be adjusted by the position to broken motorized rollers, realizes roll gap gap
Adjusting.After the completion of roll gap gap adjustment, dynamic roller is realized using positioning buting iron and is positioned.Such roll gap gap adjustment, Gong Renlao
Fatigue resistance is big, the control of roll gap gap is inaccurate, system job insecurity, is especially unsuitable for what crusher discharging-material size often changed
Workplace；Existing overload yielding device is the pressure that pressure sensor detects hydraulic cylinder, and commutation is adjusted if pressure is excessive
Valve carries out pressure yielding.Such adjusting has retardance first, is not to make a concession automatically, therefore cannot carry out in first time
It makes a concession, secondly in this way there is a possibility that dynamic roller yielding excessively, causes gap excessive.Such overload yielding device is not suitable for crusher mistake
Carry protection
