The specific embodiment
As shown in Figure 1 and Figure 2, hydraulic jaw crusher of the present invention, comprise jaw crusher, hydraulic mechanism, hydraulic mechanism comprises hydraulic jack 1, accumulator 4, pipeline, hydraulic jack 1 comprises cylinder body, piston, oil cylinder piston bar 11, oil cylinder cover 8, and piston places in the cylinder body, and oil cylinder piston bar 11 is connected with piston, the cylinder body front end is provided with oil cylinder cover 8, and oil cylinder piston bar 11 passes oil cylinder cover 8.
The cylinder body back cavity 7 of hydraulic jack 1 is communicated with accumulator 4 by pipeline, and pipeline is provided with pipe-line control valve group 6, and pipe-line control valve group 6 comprises check valve parallel with one another and choke valve.The adjustment seat 13 of jaw crusher is connected with the oil cylinder piston bar 11 of hydraulic mechanism.
Check valve in the pipe-line control valve group 6 makes the hydraulic oil in the pipeline to flow to accumulator 4 from hydraulic jack 1, and can not reverse flow.
Accumulator 4 is provided with gas supplementing opening 3 and accumulator pressure control valve 5.The cylinder body ante-chamber exhaust end of hydraulic jack 1 is provided with air filter 2.
By regulating accumulator pressure control valve 5, can regulate the air pressure in the accumulator 4, thus the oil pressure in the regulator solution compressing cylinder 1, and then regulate the amount of force that oil cylinder piston bar 11 puts on adjustment seat 13.Oil cylinder piston bar 11 puts on the active force (being the top power of oil cylinder 1) of adjusting seat 13, has determined the maximum crushing force of jaw crusher.
The present invention passes through to regulate the air pressure in the accumulator 4, can set different maximum crushing forces at different processing materials, to reach best safe effect, can exempt from the overload damage by the equipment of adequately protecting.In addition, this control method not only can be regulated maximum crushing force arbitrarily in tolerance band, and regulative mode is simple and convenient.
Hydraulic jack 1 adopts the single-acting high-voltage oil cylinder, and its piston chance barrier promptly moves back, do not have barrier and then advances.
Adjusting seat 13 is arranged on the adjustment seat guide rail 14 by rolling linear guide bearing 12.
Rolling linear guide bearing 12 can change the power transmission direction of bracket (or elbow roller), makes adjustment seat 13 can bear huge supporting force; Rolling linear guide bearing 12 also can reduce adjusts seat 13 frictional resistance when mobile on adjusting seat guide rail 14, makes to adjust seat 13 and can move flexibly adjusting on the seat guide rail 14, guarantees finishing smoothly of " eat iron, tell iron " process.
As shown in Figure 1, the piston of hydraulic jack 1 connects oil cylinder piston bar 11; Be provided with in the oil cylinder cover 8 of hydraulic jack 1 and adjust cover 11, oil cylinder piston bar 11 is arranged to be adjusted in the cover 10, and oil cylinder piston bar 11 can move freely in adjusting cover 10.Oil cylinder cover 8 with adjust between the cover 10 to being threaded, adjusting cover 10 can front and back adjusting oil cylinder cover 8 in.Be provided with lock nut 9 between oil cylinder cover 8 and the adjustment cover 10, can be positioned on the oil cylinder cover 8 adjusting cover 10.
By regulating the relative position of oil cylinder piston bar 11 and oil cylinder cover 8, can realize spacing adjustment that piston is moved ahead, thereby regulate the nesting population size of jaw crusher.The method of this adjusting nesting population size is not only easy, and can regulate nesting population size in a big way.
Operation principle of the present invention is:
When crusher chamber contains the material barrier, when moving jaw is bitten the material barrier in broken interlock stroke, the huge reaction force of the material barrier that moving jaw can be subjected to, because the reaction force of material barrier surpasses the maximum crushing force of setting, the material barrier forces moving jaw to adjust seat 13 by bracket (or elbow roller) drive and moves backward along adjusting a guide rail 14; Adjust retreating of seat 13, drive oil cylinder piston bar 11 and piston then and retreat, force the hydraulic oil oil extraction fast in accumulator 4 in the hydraulic jack 1, and make the gas in the accumulator 4 be compressed by check valve and choke valve.
In adjusting a process that the moving jaw of 13 drives retreats, moving jaw still carries out periodic gyration under the driving of motor, when moving jaw is in the idle running stroke, the reaction force of material barrier disappears, the suffered setback force of piston disappears thereupon, under the effect of Compressed Gas, the hydraulic oil in the accumulator 4 refluxes in hydraulic jack 1, and piston is pushed away forward conversely in accumulator 4.This moment, check valve place branch road was in cut-off state, and the pace of piston is controlled by choke valve.Because the oil in the hydraulic jack 1 is to flow to accumulator 4 by choke valve and check valve when piston retreats oil extraction, and is to flow back in the hydraulic jack 1 by choke valve when oil-feed, so the speed that oil cylinder piston retreats is greater than the speed that moves ahead.
Because piston-advance speed is less, can't bite the material barrier immediately, the material barrier segment distance that can fall in the idle running stroke of moving jaw will expect again to hinder when moving jaw is in broken interlock stroke once more and bite, and finish the next round actuation cycle.In this process, it is big that the size of discharge gate becomes gradually.
Through actuation cycle repeatedly, in nesting population size became big process gradually, the material barrier constantly fell, and finally is discharged from crusher chamber.After the material barrier is discharged from, the suffered setback force of piston disappears, in accumulator 4 under the effect of Compressed Gas, hydraulic oil in the accumulator 4 refluxes in hydraulic jack 1 by choke valve, oil cylinder piston slowly advances, and seat 13 is adjusted in drive and connected moving jaw moves ahead, and nesting population size progressively is decreased to initial set value, recovers original duty.
In this process, shattering process is not interrupted.Because after the material barrier was discharged, the recovery of nesting population size needed the time, in the process that nesting population size progressively reduces, discharging-material size can be subjected to temporary influence.Regulate the aperture of choke valve, the time that nesting population size is restored was controlled in the shortest time, and is very little to the shattering process influence.
The in use available pump-up device of the present invention is by irregularly tonifying Qi in accumulator 4 of gas supplementing opening 3, to keep the long-term normal operation of hydraulic mechanism.Must filling nitrogen or other inert gas in the accumulator 4.
The present invention utilizes compressed inert in the accumulator 4 as the energy-accumulating medium of hydraulic mechanism, has cancelled motor commonly used, the hydraulic energy system of oil pump.Because the present invention does not have motor, oil-less pump does not have complicated electric hydraulic control system yet, and it is simple and reliable for structure, cost is low, be convenient to maintenance, also can save power consumption simultaneously.Because barrier is told in off-load, from the situation of working continuously less generation in daily production of horizontal reset, so adopt the just energy execution of energy storage mode, so the present invention not only economy but also practicality.
The present invention by the hydraulic accumulation energy system realize off-load tell barrier, from the working continuously of horizontal reset, whole process automatically performs fully, automaticity is higher, security performance is also better.
The present invention can be used for the material that fragmentation contains more material barrier, is the ideal equipment of processing operation lines such as regulus, gangue.
Jaw crusher of the present invention also is applicable to the negative structural shape that hangs, bears supporting, elbow roll-type, and its comprehensive technical performance and economic benefit are higher.
