Description
Technical field
The utility model relates to the jaw crusher technical field, more specifically says a kind of jaw crusher of exempting spring drag link mechanism.
Background technology
Jaw crusher (as shown in Figure 1) is commonly called as " jaw broken ", is one of with the longest history, most popular disintegrating apparatus.
In the jaw crusher course of work, after motion (finishing broken work done) forward under the moving thrust of jaw at bracket, do rapidly again " return " motion, in order to repeat fragmentation circulation next time backward.Because the bracket mechanism in the broken equipment of prior art jaw is " being abutted against " structural formula (as shown in Figure 2), namely below moving jaw mechanism, offer a bracket groove of admitting bracket one end, at the volley, bracket is done the roll pivot motion in the bracket groove of moving jaw, it is characterized in that only having " unilateral thrust " motion, the sleeve spring drag link mechanism (number in the figure 111) that its " return " motion is set up by moving jaw lower end is finished, and spring drag link mechanism is to want wasted work and subtract power, it brings many drawbacks, is in particular in the following aspects:
1. complex structure.Make the jaw crusher complicated integral structure;
2. wasted work subtracts power.The return function of spring pull bar is finished by initial tension of spring, like this, just must overcome first initial tension of spring when moving jaw is done broken work done, namely increases the work done energy consumption, reduces again crushing force;
3. restriction rotating speed.Because be unilateral thrust, the outer spring drag link mechanism of establishing is realized " return ", and rotating speed is too high, and inertia is just large, can produce moment between bracket and the bracket groove to separate, therefore " being abutted against " structure is only suitable for low speed, can not realize running up;
4. generation noise.Bracket mechanism can produce the moment segregation phenomenon between bracket and the bracket groove in fast turn-around, produce bump sound, adds the creakily sound of creak loud, high-pitched sound that telescopic spring can send, and this is the main noise source of jaw crusher contaminated environment.This has also aggravated the abrasion of part simultaneously;
5. limitation function.Because breaking, the prior art jaw only has the broken work done of thrust, not work done of pulling force, and the bracket mechanism of " being abutted against " structure can also adapt to.But along with constantly bringing forth new ideas of the broken technology of jaw, the two-way operating mode that all needs work done of thrust and pulling force need to appear.The bracket mechanism of " being abutted against " structure has obviously limited the lifting of the broken function of jaw.
