Abstract
The utility model discloses a jaw crusher with a hydraulic cylinder for a spring drag link mechanism, which comprises a draw link, a lower spring seat, a spring, the hollow hydraulic cylinder, a gasket and a locking nut, wherein the lower spring seat is positioned in a support of a rear wall of the jaw crusher, one end of the spring is arranged in the lower spring seat, the other end of the spring is connected with the hollow hydraulic cylinder, and the spring is connected with the draw link through the gasket and the locking nut. The jaw crusher with the hydraulic cylinder for the spring drag link mechanism is capable of automatically adjusting spring force and automatically tensioning the draw link with constant force after a jaw crushing discharging port is adjusted.
Description
Technical field
The utility model relates to a kind of jaw crusher, particularly a kind of jaw crusher of spring drag link mechanism band hydraulic cylinder.
Background technology
As shown in Figure 1, the single toggle jaw crusher on the market comprises pull bar 1, lower spring cup 3, spring 4, upper spring seat 5, locking nut 6 now, and the following hinge of pull bar 1 links through bearing pin, packing ring, split pin and moving jaw bottom; Lower spring cup 3 places in the bearing of wall 2 behind the jaw crusher, and an end of spring 4 places in the lower spring cup 3, and the other end of spring 4 links with pull bar 1 through locking nut 6, upper spring seat 5.Existing single toggle jaw crusher is through tightening the decrement that locking nut 6 comes regulating spring 4, thus the tightening force of the broken moving jaw of 1 pair of jaw of adjusting yoke.Existing single toggle jaw crusher can be realized the basic function that jaw is broken; But when the broken adjustment of jaw discharge gate size, must manual work unclamp locking nut 6 in advance, and after having adjusted discharge gate; Also need manual work to tighten this locking nut; Therefore following shortcoming is arranged: one, manually-operated can not can both guarantee effective decrement of spring to cause pull bar that the pulling force of moving jaw is varied at every turn.When pulling force is big, increase the pressure of bracket, caused the increase of additional wear and power consumption; Pulling force hour can cause the loosening of bracket, causes the bump and the abnormal sound of part such as bracket, can cause coming off of bracket, accidental interruption production and possible accident when serious; Two, manually-operated can't realize the automatic adjustment of discharge gate; Three,, then have influence on the realization of the automation adjustment of discharge gate because of adjusting automatically.
The utility model content
The utility model technical problem to be solved provides a kind of jaw crusher of spring drag link mechanism band hydraulic cylinder, after it can be realized the automatic adjustment of spring force and adjust the broken discharge gate of jaw automatically with constant force tensioning pull bar.
For solveing the technical problem; The utility model provides a kind of jaw crusher of spring drag link mechanism band hydraulic cylinder; The jaw crusher of spring drag link mechanism band hydraulic cylinder comprises pull bar, lower spring cup, spring, and lower spring cup places in the bearing of wall behind the jaw crusher, and an end of spring places in the lower spring cup; It is characterized in that; The jaw crusher of spring drag link mechanism band hydraulic cylinder also comprises hollow hydraulic cylinder, packing ring, locking nut, and the other end of spring and hollow hydraulic cylinder join, and spring is connected with pull bar through packing ring, locking nut.
Preferably, said hollow hydraulic cylinder is between spring and locking nut.
The positive progressive effect of the utility model is: automatically with constant force tensioning pull bar, reduce disorderly closedown and guarantee is provided for the serialization production of various broken production lines after the utility model can be realized the automatic adjustment of spring force and adjust the broken discharge gate of jaw.
Description of drawings
Fig. 1 is the structural representation of existing single toggle jaw crusher.
Fig. 2 is the structural representation of the jaw crusher of the utility model spring drag link mechanism band hydraulic cylinder.
The specific embodiment
Lift a preferred embodiment below, and combine accompanying drawing to come the clearer the utility model of intactly explaining.
As shown in Figure 2; The jaw crusher of the utility model spring drag link mechanism band hydraulic cylinder comprises pull bar 11, lower spring cup 13, spring 14, hollow hydraulic cylinder 15, packing ring 16, locking nut 17, and the following hinge of pull bar 11 links through bearing pin, packing ring, split pin and moving jaw bottom; Lower spring cup 13 places in the bearing of wall 12 behind the jaw crusher; And an end of spring 14 places in the lower spring cup 13; The other end of spring 14 and hollow hydraulic cylinder 15 join; Spring 14 is connected with pull bar 11 through packing ring 16, locking nut 17, and hollow hydraulic cylinder 15 is between spring 14 and locking nut 17.The jaw crusher of the utility model spring drag link mechanism band hydraulic cylinder is to come regulating spring 14 to initial compression amount (decrement=0) through rotational lock nut 17, exerts pressure through 15 pairs of springs 14 of hollow hydraulic cylinder, reaches the rated operating pressure of spring.The operating pressure of hollow hydraulic cylinder 15 keeps constant by hydraulic system.
The detailed process that the utility model is regulated the broken discharge gate size of jaw is following: " automatic/hand " master switch on the console is screwed into " manually " gear; Start-up control " pull bar oil cylinder retraction " button cashier's office in a shop comes control spring back to nature state through the pressure gauge reading of observing hydraulic system.Be equivalent to former manual work and unclamp locking nut this moment; After having reconciled the broken discharge gate of jaw, " automatic/hand " master switch is screwed into " automatically " gear, then hollow hydraulic cylinder 15 is elongated to former active length (setting pressure by hydraulic system guarantees) automatically, guarantees the constant pulling force of pull bar to moving jaw.
The utility model guarantees that the detailed process of automatic iron excessively is following: non-broken thing appears in the crusher chamber at disintegrating machine, and disintegrating machine is incompetent with it fragmentation, is referred to as " crossing iron ".Cause bracket place pressure to heighten because reduction resistant force doubles this moment, the same and stressed increase of the joining adjustment hydraulic cylinder of bracket; This power will surpass the force value that hydraulic system is set in moment, and the safety overflow valve in the system is opened, and bracket bounces back automatically; Strengthen discharge gate, get rid of foreign matter; In above process, because bracket bounces back, and the spring pressure on the pull bar is die-offed, length has the trend of extending immediately simultaneously; But because the hollow hydraulic cylinder behind the spring keeps constant pressure (having accumulator to keep in the hydraulic system) always; The hollow hydraulic cylinder extends automatically; To replenish the elongation of spring, cause pull bar still can keep constant pulling force, and the spring lower end also can still tightly be against on the original position to moving jaw bottom; After crossing iron, bracket place pressure reduces rapidly, and hydraulic cylinder promotes bracket self-return when discharge gate (former position) under system pressure.Simultaneously, since moving jaw return, the pull bar that links with it reach, the spring pressure on the pull bar increases, and compression hollow oil cylinder retraction is once crossed the iron self-regulating process up to former normal operation position thereby accomplished.
In sum, automatically with constant force tensioning pull bar, reduce disorderly closedown and guarantee is provided for the serialization production of various broken production lines after the utility model can be realized the automatic adjustment of spring force and adjust the broken discharge gate of jaw.
Though more than described the specific embodiment of the utility model; But those skilled in the art is to be understood that; These only illustrate, and under the prerequisite of principle that does not deviate from the utility model and essence, can make numerous variations or modification to these embodiments.Therefore, the protection domain of the utility model is limited appended claims.
