Abstract
The utility model provides a kind of impact rack adjusting device of impact breaker, this impact rack adjusting device is fixed in the frame of this impact breaker, this impact rack adjusting device includes hydraulic cylinder, spring, adjustment swivel nut, adjustment screw mandrel, adjusting nut, adjusting seat, this adjustment screw mandrel is connected with impact rack, and this impact rack adjusting device also comprises multiple pad be arranged between this adjusting nut and this frame.The utility model, by increasing the known pad of thickness, convenient and swiftly can ensure again that the adjustable range of two screw mandrels is synchronous effectively, ensures the gap uniformity between bar and impact rack thus, uses crushing effect better.
Description
Technical field
The utility model relates to a kind of impact rack adjusting device, particularly a kind of impact rack adjusting device of impact breaker.
Background technology
In ore reduction machinery field, because the operation principle of disintegrating machine is different, therefore according to the requirement of mineral product, various types of disintegrating machine can be selected.For the ore of broken identical type, as jaw crusher, its disposal ability is larger than common single-rotor impact crusher, and the ratio of reduction of jaw crusher is 4 ~ 7, and jaw crusher is commonly used to coarse crushing.And the ratio of reduction of common single-rotor impact crusher reaches 10 ~ 40, be commonly used to the materials such as crushed stone lime stone, asbestos deposit, coal, dolomite, concrete, can be used for thick, in broken.
Existing single-rotor impact crusher structure is made up of (see Fig. 1) frame 1, first impact rack 2, second impact rack 3, rotor 4, impact rack adjusting device 5.Frame 1 is by steel plate and being welded, and the overhung of frame 1 has the first impact rack 2 and the second impact rack 3 and impact rack adjusting device 5, and the centre of frame 1 is provided with rotor 4.Rotor 4 is provided with bar, bar wedge, main shaft and rotor support body etc.
When material falls in the crusher chamber formed between impact rack and rotor, be subject to the bar impact grinding of High Rotation Speed and impelling on impact rack, and to rebound back bar from impact rack at a high speed, clashed into mutually by the material that rotor is dished out again in fracture area simultaneously, material is broken again, repeatedly said process.When material is less than the gap between impact rack and bar, just discharge from the discharging opening of framework soleplate.Thus reach broken effect.
The impact rack adjusting device of original impact breaker is made up of (see Fig. 2) hydraulic cylinder 51, spring 52, adjustment swivel nut 53, adjustment screw mandrel 55, adjusting nut 54, adjusting seat 56 etc.When impact breaker is after fragmentation after a while, the wearing and tearing of bar and beating lining plate can be caused, so the gap between bar and beating lining plate can be made to become large, the requirement of particle size after cracking can not be met, at this moment must adjust the gap between bar and impact rack.When needing the gap reduced between bar and impact rack, unscrew adjustment swivel nut 53, by hydraulic cylinder by adjusting seat to " afterwards " direction pressure go (in Fig. 2 with upwards for rear to, be downwards front to, dotted line represents the position of the adjustment swivel nut after adjustment, represent with Reference numeral 53a), until collide with adjustment swivel nut (i.e. the position of dotted line), then adjusting nut 54 is moved (namely moving up) to " afterwards " direction.Finally unclamp hydraulic cylinder 51, now adjusting seat 56 and adjustment screw mandrel 55, impact rack 2 (or 3) etc. move (moving down) to " front " direction simultaneously, thus reach the gap reduced between bar and impact rack, this method of adjustment seems simple, but it is very not directly perceived to have adjusted how many positions before and after actual adjustment screw mandrel, often cause the adjustment screw mandrel length of two sides inconsistent, the gap forming bar and impact rack in chamber is uneven, causes crushing effect not good.
Utility model content
The technical problems to be solved in the utility model being difficult to intuitively to overcome the adjusting device of impact rack in prior art, accurately controlling adjusting range thus causing the inconsistent defect causing crushing effect not good of the actual adjustment length of both sides, provides a kind of impact rack adjusting device that accurately can control the impact breaker of the position adjustment situation of impact rack.
The utility model solves above-mentioned technical problem by following technical proposals:
A kind of impact rack adjusting device of impact breaker, this impact rack adjusting device is fixed in the frame of this impact breaker, this impact rack adjusting device includes hydraulic cylinder, spring, adjustment swivel nut, adjustment screw mandrel, adjusting nut, adjusting seat, this adjustment screw mandrel is connected with impact rack, its feature is, this impact rack adjusting device also comprises multiple pad be arranged between this adjusting nut and this frame.
Preferably, those pads are mutually stacked.
Preferably, the thickness of each pad is identical.
Preferably, the thickness of at least two pads in those pads is not identical.
Preferably, the thickness of each pad is known.
Positive progressive effect of the present utility model is: this adjusting device adds the pad for adjusting spacing on the original basis, and this pad can be divided into the thickness of all size for user.When needing the gap reduced between bar and impact rack, do not need to unscrew adjustment swivel nut, as long as by hydraulic cylinder by adjusting seat, together with adjustment swivel nut, adjustment screw mandrel, adjusting nut to away from impact rack direction pressure go, take out the adjustment pad needing the thickness taken away, unclamp hydraulic cylinder again, the gap of thickness of taking out adjustment pad can be reduced between bar and impact rack, so not only convenient and swift but also can effectively ensure the synchronous of two screw mandrels.Also can ensure the gap uniformity between bar and impact rack, use crushing effect better.
Accompanying drawing explanation
Fig. 1 is the structural representation of the impact breaker of prior art.
Fig. 2 is the structural representation of the impact rack adjusting device of the impact breaker of prior art.
Fig. 3 is the structural representation of the impact rack adjusting device of the impact breaker of another embodiment of the utility model.
Detailed description of the invention
Lift preferred embodiment below, and come by reference to the accompanying drawings clearlyer intactly the utility model to be described, only illustrate below, therefore the utility model is not limited among described scope of embodiments.
Embodiment 1
With reference to figure 3, this impact rack adjusting device is fixed in the frame of this impact breaker, this impact rack adjusting device includes hydraulic cylinder 51, spring 52, adjustment swivel nut 53, adjustment screw mandrel 55, adjusting nut 54, adjusting seat 56, this adjustment screw mandrel 55 is connected with impact rack (still representing with Reference numeral 2 (3)), and this impact rack adjusting device also comprises multiple pad 57 be arranged between this adjusting nut and this frame.
The adjusting device of the present embodiment adds the pad 57 for adjusting spacing on the original basis, when needing the gap reduced between bar and impact rack, do not need to unscrew adjustment swivel nut, as long as by hydraulic cylinder by adjusting seat, together with adjustment swivel nut, adjustment screw mandrel, adjusting nut goes (namely in Fig. 3 direction) upwards to the direction pressure away from impact rack together, take out the adjustment pad needing the thickness taken away, unclamp hydraulic cylinder again, the gap of the thickness taking out adjustment pad can be reduced between bar and impact rack, so not only, fast but also can effectively ensure the synchronous of two screw mandrels.Also can ensure the gap uniformity between bar and impact rack, use crushing effect better.
