Abstract
A jaw crusher includes a frame, and a side liner component. An eccentric shaft is mounted on the frame through a bearing pedestal; flywheels are arranged at two ends of the eccentric shaft, wherein one of the flywheels serves as a transmission wheel; a movable jaw component is mounted on the eccentric shaft; a fixed tooth plate is mounted in a position corresponding to the movable jaw component; one end of an adjusting base is mounted on the rear side of the frame, and the other end of the adjusting base is matched with the lower part of the movable jaw component; one end of the pull rod is connected with the movable jaw component, and the other end of the adjusting base is mounted on the rear side of the frame; and a spring is mounted on the other end of the pull rod. The jaw crusher improves the working efficiency, reduces land occupation of the machine, saves cost, and fills a gap in the series of jaw crushers with the disjunction machine type.
Description
Technical field
The utility model relates to field of cracking machine, particularly a kind of jaw crusher.
Background technology
Existing jaw crusher series also has PEX320 * 760 jaw crushers or PE400 * 600 jaw crushers except that PE250 * 400 jaw crushers.But the latter's price is several times of the former price, and some user thinks that the broken type of PE250 * 400 jaws is less than normal, efficient is too low inapplicable when reality is used, and PEX320 * 760 jaws are broken or the broken type of PE400 * 600 jaws is bigger than normal, and investment is had any problem.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of jaw crusher, by the design of optimizing structure, can make specification reach PE300 * 500, and efficient is higher, and production cost is lower.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of jaw crusher, comprise frame, side plate assembly, eccentric shaft is installed on the frame by bearing block, the eccentric shaft two ends are provided with flywheel, one of them flywheel is also as drive, and moving jaw assembly is installed on the eccentric shaft, and fixed tooth plate is installed in and moves jaw assembly opposite position;
Adjust base one end and be installed in the frame rear side, the other end cooperates with moving jaw assembly bottom;
Pull bar one end is connected with moving jaw assembly, and the other end is installed in the frame rear side, which is provided with spring.
In the described moving jaw assembly, moving jaw plate is fixedly mounted on the floor, and the floor bottom is provided with drag hook, is connected with pull bar by drag hook, and the drag hook top also is provided with groove.
Profile of tooth cross section on fixed tooth plate and the moving jaw assembly in echelon.
A kind of jaw crusher that the utility model provides, adopt the design of round trip flight wheel, eccentric shaft, equipment operates steadily, reliably, and the moving jaw assembly of optimal design cooperates with adjustment base and pull bar, the jaw assembly is also done in compressional movement rubbed reciprocating motion, improved operating efficiency.Adjust the adjusting bolt and can regulate the distance of moving between jaw assembly and the fixed tooth plate, thus the particle size after cracking of control ore.Pull bar combines closely the jaw assembly by the inertia force that spring comes the moving jaw assembly of balance to be produced, and is unlikely separation.When moving jaw assembly retreated, spring can play synergism again.
The utility model has improved operating efficiency, reduces the machine land used, saves cost; Filled up disconnection type blank in the jaw crusher series.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a front view of the present utility model.
Fig. 3 is the front view of floor in the utility model.
Fig. 4 is the right view of floor in the utility model.
Fig. 5 is the rearview of floor in the utility model.
The specific embodiment
In Fig. 1, Fig. 2, a kind of jaw crusher, comprise frame 1, side plate assembly 3, eccentric shaft 4 is installed on the frame 1 by bearing block, eccentric shaft 4 two ends are provided with flywheel 7, and one of them flywheel 7 is used for being connected with drive unit 9 also as drive, moving jaw assembly 5 is installed on the eccentric shaft 4, and fixed tooth plate 2 is installed in and moving jaw assembly 5 opposite positions;
Adjust base 6 one ends and be installed in frame 1 rear side, the other end cooperates with moving jaw assembly 5 bottoms;
In Fig. 3, Fig. 4, Fig. 5, in the described moving jaw assembly 5, moving jaw plate is fixedly mounted on the floor, the floor bottom is provided with drag hook, be connected with pull bar 8 by drag hook, the drag hook top also is provided with groove, and this groove is used to hold the end of adjusting base 6, and the distance between moving jaw assembly 5 of pull bar 8 engagement limits and the fixed tooth plate 2.Bracket is the part to moving jaw plate transmission campaign, is again the safeties of disintegrating machine.Moving jaw plate bears pressure at work, generally adopts the cast iron whole cast.Profile of tooth cross section on fixed tooth plate 2 and the moving jaw assembly 5 in echelon, stepped tooth is more conducive to the fragmentation of ore nor is easy to wear.
Movable moving jaw assembly 5 carries out the reciprocating motion that curshed zone is rubbed facing to fixed tooth plate 2.When moving jaw assembly 5 separated with fixed tooth plate 2, material entered crusher chamber, and simultaneously broken good finished product is discharged from the bottom of disintegrating machine; When moving jaw assembly 5 and fixed tooth plate 2 come to a time-out, the material that enters crusher chamber is squeezed active force that band rubs makes the material fragmentation thereby material bent with slabbing action, and material is realized broken overall process.
