Description
Technical field
The utility model relates to a kind of disintegrating machine technical field, particularly relates to a kind of jaw crusher.
Background technology
Jaw crusher by moving jaw and quiet jaw two pieces of jaws form crusher chamber, two jaw movements of simulated animal and complete the disintegrating machine of material crushing operation.Be widely used in the fragmentation of various ore and bulk materials in the industries such as mine smelting, building materials, highway, railway, water conservancy and chemical industry.Jaw crusher in mine, building materials, the department such as capital construction be mainly used as boulder crusher and intermediate crusher.Be divided into three kinds, large, medium and small type according to charging aperture width size, what charging aperture width was greater than 600MM is heavy-duty machines, and charging aperture width is medium-sized machine 300-600MM's, and what charging aperture width was less than 300MM is minicomputer.Jaw crusher structure is simple, easy to manufacture, reliable operation.
The working portion of jaw crusher is two pieces of jaws, one is fixed jaw (determining jaw), and vertical (or upper end slightly flare) is fixed on body antetheca, and another is sewing jaw (dynamic jaw), inclined position, forms up big and down small crusher chamber (working chamber) with fixed jaw.Sewing jaw does periodic reciprocating motion facing to fixed jaw, time and separate, time and close.Time separately, material enters crusher chamber, and finished product draws off from bottom; Near time, the material be contained between two pieces of jaws is squeezed, bending and slabbing action and broken.
Jaw crusher is different according to the swing mode of sewing jaw, can be divided into simple swing type jaw crusher (simple pendular jaw crusher).Toggle-type jaw crusher (single toggle jaw crusher) and comprehensive swing type jaw crusher three kinds.Be broken in the process of finger stone by huge stone, first disintegrating machine is generally " master " disintegrating machine.History is the longest, and also the firmest disintegrating machine is jaw crusher.During for jaw crusher feeding, material pours the crushing chamber containing jaw tooth into from top entry, jaw tooth with immense strength by material top to locular wall, it is broken into less stone.What support the motion of jaw tooth is that a bias is lived, and this eccentric shaft runs through framework of fuselage.Eccentric motion produced by the flywheel being fixed on axle two ends usually.Flywheel and eccentric radial journal bearing often adopt spheric roller bearing, and bearing must bear huge shock loading, abrasion sewage and high temperature.
Current existing jaw crusher complex structure, installs inconvenient crushing efficiency lower.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of compact conformation, easy for installation, and stability in use is good, and crushing effect is good, the jaw crusher that crushing efficiency is high.
For solving the problem, the utility model adopts following technical scheme:
A kind of jaw crusher, comprise frame, eccentric shaft, flywheel and fixed jaw, described flywheel is located in frame, described flywheel and eccentric shaft are in transmission connection, described fixed jaw is located at frame front end, described fixed jaw is fixedly connected with frame, eccentric shaft can be with moving tooth plate back and forth to shake, material is broken between tooth plate and fixed jaw, crushing efficiency is high, bracket, adjusting seat and the very heavy toothed plate structure that can keep of separate type are stablized, locking spring can keep tooth plate to be in broken state all the time, support bar and supporting seat can reduce impact during toothed plate crushing material, convenient installation, stability in use is high, tooth plate is provided with below described eccentric shaft, described tooth plate is that inclination angle is arranged, bracket and pull bar is provided with below described tooth plate, described bracket one end is connected with adjusting seat and separating jack, described tooth plate, bracket, adjusting seat is connected successively with separating jack, described pull bar one end is provided with locking spring, described adjusting seat is provided with supporting seat and support bar, described support bar respectively with supporting seat and tooth plate hinged.
