Abstract

The utility model relates to a compound pendulum jaw crusher hydraulic backwall which comprises an adjusting base, a knee plate, a backwall body as well as a sizing block, a hyduralic cylinder, a displacement sensor and a hydraulic station, wherein the adjusting base is clamped in a U-shaped groove of the backwall body through slideways on two sides of the U-shaped groove of the backwall body, and can slide along the slidways; the knee plate is arranged on the adjusting base; a cylinder rod of the hydraulic cylinder is connected with the backwall body through a flange; the cylinder rod penetrates through a backwall web and is connected with the sizing block through a locking block; the sizing block stretches and withdraws along the cylinder rod of the hydraulic cylinder and slides inside the U-shaped groove of the backwall so as to push the adjusting base to slide; the displacement sensor is positioned inside a hollow cylinder at the tail of the cylinder rod; the hydraulic station is connected with the hydraulic cylinder through a high-pressure oil tube. A function that the size of a jaw discharge hole is automatically adjusted is achieved, a function of automatic 'reset' in working is achieved, that is, after 'iron is passed', a crusher can be automatically reset, and the size of the discharge hole is kept unchanged, the continuous working is achieved, and the production efficiency is improved.

Description

Wall after single toggle jaw crusher fluid pressure type

Technical field

The utility model relates to a kind of disintegrating machine, relates in particular to the rear wall construction of this disintegrating machine.

Background technology

On market, mostly the rear wall of single toggle jaw crusher is by the version that contains adjusting shims (as Fig. 1) or voussoir (as Fig. 2) now.

As seen from Figure 1, " containing the rear wall of adjusting shims " mainly by: adjusting seat 1, adjusting shims 2, rear wall 3, adjusting lever 4 form.Adjusting " adjusting seat 1 " position (being corresponding adjusting discharge gate size), first shut down, unclamp the locking nut of adjusting lever 4, screw adjusting lever 4, back down adjusting seat 1; Realize by the pad quantity (thickness) that increases or reduce adjusting shims 2 size that reduces or increase discharge gate; Then unclamp adjusting lever 4, locking " adjusting shims ", completes once and adjusts; This structural principle is simple, be convenient to manufacture, but " heaviness " cannot realize electrodeless adjusting, operate more loaded down with trivial detailsly, and workload is large, and necessary manual operation, cannot realize automatic control and work continuously; In figure: bracket 5 brackets 5 are adjusting seat 1 and the motor-driven jaw bottom linker of jaw crushing, by the movement of this bracket, will promote moving jaw bottom and swing, and reach and regulate discharge gate size object.

As seen from Figure 2, " containing the rear wall of voussoir " mainly formed by adjusting seat 10, one group of voussoir 11, rear wall 13, adjusting rod 14.This structure moves up and down by adjusting rod 14, and two voussoirs are relatively moved, thereby adjusting seat 10 is released or retracted to total thickness variations, reaches the object of adjusting discharge gate; This structure can realize the electrodeless adjusting of discharge gate in certain limit, needs equally manual operation, in the time regulating, needs to shut down, and does not support automatic control.In figure: bracket 15 is adjusting seat 10 and the motor-driven jaw bottom linker of jaw crushing, by the movement of this bracket, will promote moving jaw bottom and swing, and reach and regulate discharge gate size object.

Summary of the invention

The utility model technical issues that need to address have been to provide wall after a kind of single toggle jaw crusher fluid pressure type, are intended to solve the above problems.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:

The utility model comprises: adjusting seat, bracket, Hou Qiang; Described adjusting seat is stuck in rear wall U-lag by the slideway (upper and lower supporting plate) that is arranged on U-lag both sides in rear wall, can move along slideway; Described bracket is placed in adjusting seat; Also comprise: parallels, hydraulic cylinder, displacement transducer and Hydraulic Station; The cylinder bar of described hydraulic cylinder is connected on rear wall by flange, and cylinder bar is connected with parallels by lock dog through rear wall web; Described parallels is flexible with the cylinder bar of hydraulic cylinder, in the U-lag of rear wall, slides, and slides thereby promote adjusting seat; Described displacement transducer is positioned at the hollow cylinder of cylinder bar afterbody; Hydraulic Station is connected with hydraulic cylinder by high-pressure oil pipe.

Compared with prior art, the beneficial effects of the utility model are: the function that can realize the broken discharge gate size of automatic adjusting jaw; Can there is automatic " reset " function in work---after disintegrating machine " is crossed iron ", automatically set back, keep discharge gate size constant; Can work continuously, improve production efficiency.

Detailed description of the invention

Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail:

As seen from Figure 3: the utility model comprises: adjusting seat 100, bracket 106, rear wall 101; Described adjusting seat 100 is stuck in rear wall U-lag by the slideway (upper and lower supporting plate) that is arranged on U-lag both sides in rear wall 101, can move along slideway; Described bracket 106 is placed in adjusting seat 100; Also comprise: parallels 105, hydraulic cylinder 102, displacement transducer 103 and Hydraulic Station 104; The cylinder bar of described hydraulic cylinder 102 is connected on rear wall 101 by flange, and cylinder bar is connected with parallels 105 by lock dog through rear wall web; Described parallels 105 is flexible with the cylinder bar of hydraulic cylinder 102, in the U-lag of rear wall 101, slides, and slides thereby promote adjusting seat 100; Described displacement transducer 103 is positioned at the hollow cylinder of cylinder bar afterbody; Hydraulic Station 104 is connected with hydraulic cylinder 102 by high-pressure oil pipe.

Adjusting seat in the utility model, bracket are same as the prior art.

As seen from Figure 4, parallels 105 is flexible with the cylinder bar of hydraulic cylinder 102, in the U-lag of rear wall 101, slides, and slides thereby promote adjusting seat 100; Swing by the moving jaw 107 of bracket 106 promotion again because bracket 106 is placed in adjusting seat 100, reach and adjust discharge gate 108 objects.The action of hydraulic cylinder 102, completes by Hydraulic Station 104 " commander ".

The utility model drives hydraulic cylinder bar flexible by Hydraulic Station.In the time that hydraulic cylinder bar is stretched (or contracting) to needs position, the locking of hydraulic cylinder oil circuit, disintegrating machine is just worked under this discharge gate---normally works; In the time that crusher chamber enters non-broken thing (as teeth, broken tup etc.), the power passing on hydraulic cylinder will increase suddenly, cause hydraulic cylinder oil pocket internal pressure to increase and be greater than Hydraulic Station hydraulic system setting pressure, relief valve is opened, cylinder bar retraction, increase discharge gate, successively increase, until foreign matter can be got rid of to crusher chamber; Crusher chamber foreign matter is got rid of, and pressure reduces, under hydraulic system pressure effect, cylinder bar stretches out, and reduces discharge gate, until the position that cylinder bar intrinsic displacement sensor sets, be the discharge gate size position of former setting, system locks hydraulic cylinder, again starts normal work.---" the automatic iron of crossing "; Therefore plant function, all lower adjustings in working order, just for the continuous operation of disintegrating machine provides feasible pattern.
