Description
Technical field
The present invention relates to a kind of new type jaw crusher jaw lash adjusting device, it belongs to a kind of novel jaw lash adjusting device of jaw crusher in the mining equiment.This adjusting device is characterised in that disintegrating machine is in duty and can adjusts the jaw gap at any time, neither needs shutdown and pine to unload bolt, also needn't increase the support plate pad, operates both simple and flexible, and is safe and reliable again, also improved production efficiency of equipment.
Technical background
Jaw crusher is a rock crushing plant important in the mining machinery, and its smashing principle is by one one action of closing between the jaw, and oversize rock material is crushed to tiny building stones.When broken building stones, need the dimensional requirement of building stones up to specification is adjusted in the jaw gap,, also can become big because of the jaw wearing and tearing make its gap even adjusted, the building stones size is also inevitable to become big thereupon, and this just needs in time to adjust the jaw gap makes its building stones dimensional requirement up to specification.Therefore the jaw lash adjusting device just becomes the important mechanism of jaw crusher.
In original jaw crusher, adjusting the jaw gap solves by increasing the support plate pad entirely, be that the jaw wearing clearance becomes greatly, earlier jaw crusher is stopped to produce, bolt with the fixed supported slab seat all unclamps then, backs down support plate base with leading screw again and makes it to produce a fixed gap, again the pad of choosing is put into the space, withdraw from leading screw subsequently, the production of could starting shooting of fastening good all bolts.The adjustment jaw gap of going round and beginning again so not only bothers very much, and very dangerous, has also directly influenced the production efficiency of disintegrating machine.
In order to overcome the shortcoming and defect of original jaw crusher jaw lash adjusting device, the object of the invention is to provide a kind of novel jaw lash adjusting device, this adjusting device is when adjusting the jaw gap, both need not unload the support plate base fastening bolt by pine, needn't increase multilayer support plate pad again, can under the disintegrating machine duty, adjust the jaw gap at any time, both convenient, flexible, safe and reliable, improved the production efficiency of disintegrating machine again.
The objective of the invention is to realize by following technical measures, a kind of new type jaw crusher jaw lash adjusting device is characterized in that being made up of support plate 1, support plate base 2, adjustment wedge 3 and 3a, square screw 4 and 4a, adjustment leading screw 5, side watt seat 6 and 6a, adjustment wheel 7 and 7a, support square chest 8, adjustment hole 9.Wherein support plate 1 rear side is supported in the support plate base 2 front side grooves, two inclined-planes of support plate base 2 rear sides contact with inclined-plane, 3a front side with two adjustment wedges 3, adjust wedge 3 and contact with the bottom surface of supporting square chest 8 with the 3a side plane, support plate base 2 and adjustment wedge 3 and 3a are installed in and support in the square chest 8; Adjust chamber, the side of being provided with in wedge 3 and the 3a, in square screw 4 and the chamber, the 4a side of being installed in, left side and the right side of adjusting wedge 3 and 3a are provided with circular hole, adjust the both sides of leading screw 5 and pass from circular hole; Left side and the right side of adjusting leading screw 5 are processed into right-handed thread and left-hand thread screw thread respectively, also are processed into right-handed thread and left-hand thread screw thread with its equipped square screw 4 and 4a, adjust the installation of leading screw 5 two ends and adjust wheel 7 and 7a, adjust wheel 7 and 7a and are provided with adjustment hole 9.
The front side of support plate 1 is supported in the groove of moving gnathosoma 10 downsides, on the moving gnathosoma 10 sewing jaw 11 is installed, and fixed jaw 12 is installed on the frame casing 13 of disintegrating machine, between sewing jaw 11 and fixed jaw 12, is provided with the jaw gap 14 of certain size.
Advantage of the present invention
1, because the present invention adopts a pair of adjustment wedge 3 and 3a relative movement mode to adjust the jaw gap, therefore having overcome original disintegrating machine adjusting device must increase the shortcoming that the support plate pad could be adjusted the jaw gap, and it was both convenient, flexible to operate, safe and reliable again.
2, because original disintegrating machine adjusting device, the support plate pad must be increased and the jaw gap could be adjusted, and cushioning many must cause that " void " connects between the pad, like this when broken building stones, support plate base not only will bear immense pressure, and also bears flexure stress repeatedly, therefore very easily causes support plate base to rupture at T type groove place, and the present invention adopts a pair of adjustment wedge 3 and 3a relative movement mode to adjust the jaw gap, do not exist support plate base " void " to connect phenomenon, has therefore avoided the support plate base fracture accident to take place.
3, because the present invention adopts a pair of adjustment wedge 3 and 3a relative movement mode to adjust the jaw gap; therefore when adjusting the jaw gap; do not need to shut down; also needn't unload bolt and increase the support plate pad by pine; but adjust the jaw gap in working order at any time; not only convenient, flexible, also improved disintegrating machine production efficiency.
Description of drawings

Fig. 2, new type jaw crusher jaw lash adjusting device side view
Fig. 3, adjustment wedge cutaway view
Among the figure, 1, support plate 2, support plate base 3, adjust wedge (3a is that wedge is adjusted on the right side) 4, square screw (4a is the square screw in right side) 5, adjust leading screw 6, side watt seat (6a is a right side side watt seat) 7, (7a is a right side adjustment wheel) 8 of adjusting wheel, support square chest 9, adjust hole 10, moving gnathosoma 11, sewing jaw 12, fixed jaw 13, frame casing 14, jaw gap
See Fig. 1
Support plate 1 rear side is supported in the groove of support plate base 2 front sides, and two inclined-planes of support plate base 2 rear sides are pressed in to be adjusted on wedge 3 and the inclined-plane, 3a front side, adjusts wedge 3 and 3a side plane and is pressed on the baseplane of supporting square chest 8; Square screw 4 and 4a are installed in the square chamber of adjusting wedge 3 and 3a, two square screws 4 and 4a, adjustment wedge 3 and 3a are passed in positive and negative screw thread position, adjusting screw 5 both sides, adjusting screw 5 both sides are installed in by side watt seat 6 and 6a and support square chest 8 both sides, at adjusting screw 5 two ends regulating wheel 7 and 7a are installed, six adjusting holes 9 are set on it.
See Fig. 2
Support plate 1 front side is supported in moving gnathosoma 10 bottom grooves, moving gnathosoma 10 installed in front sewing jaws 11, and fixed jaw 12 is installed on the frame casing 13, is provided with the jaw gap 14 of broken building stones between sewing jaw 11 and fixed jaw 12.
See Fig. 3
Adjust chamber, the side of being provided with in wedge 3 and the 3a, in square screw 4 and the chamber, the 4a side of being installed in, the left and right side of adjusting wedge 3 and 3a arranges circular hole, and adjusting screw 5 passes from circular hole.
Specific embodiments
(seeing Fig. 1, Fig. 2, Fig. 3) will adjust jaw gap 14 according to the building stones specification requirement when jaw crusher fragmentation building stones, especially when the jaw wearing and tearing cause the jaw gap to become big, need adjustment jaw gap 14 in time.Adopt the present invention to adjust the jaw gap, as long as being inserted adjustment hole 9, moving rod rotates adjustment wheel 7, adjust leading screw 5 promptly rotates thereupon, because the leading screw both sides are positive and negative button screw threads, so square screw 4 and 4a can promote two adjust wedges 3 and 3a relatively near or separates, when its relatively near the time, two inclined-planes promote support plate base 2 and support plate 1 moves forward, the also reach and close thereupon of moving simultaneously gnathosoma 10 and sewing jaw 11 to fixed jaw 12, at this moment jaw gap 14 diminishes; When adjusting that wedge 3 is relative with 3a to be left, move behind support plate base 2 and the support plate 1 on the contrary, moving gnathosoma 10 and sewing jaw 11 also with after move, jaw gap 14 changes at this moment are greatly.
