Abstract
The utility model relates to a novel jaw type crusher which adopts a double crank mechanism and comprises a driving eccentric shaft, a driven eccentric shaft, a moving jaw plate and a fixed jaw plate. The two eccentric shafts are respectively installed in two lantern rings on the moving jaw plate. The two eccentric shafts whose eccentric distance and assembly direction are identical move in identical direction and speed, so that the moving jaw plate makes combined motion with identical luffing. The moving jaw plate, therefore, makes reciprocating movement that approaches and then leaves away from the fixed jaw plate so as to crush ores. The jaw type crusher has the advantages of strong crushing force, homogeneous abrasion of the jaw plate, low energy consumption, low matching power and simple operation, suitable for crushing various ores, especially suitable for small country towns that lack power.
Description
The utility model relates to the palate formula breaker in the ore reduction operation
In ore processing, it is a lot of that palate formula breaker is used.This device has the history of 103 more than ten years.Though through repeatedly improving, do not have great change in the meantime from structural principle.No matter be letter pendulum palate formula breaker, still physical pendulum palate formula breaker, its operation principle is basic identical, all is that moving palate plate centers on suspended axle and fixing palate is done periodic reciprocating motion comes breaking ores, and different is moving palate plate movement locus difference to some extent.Above-mentioned two kinds of device effects are all fine, but its moving palate plate amount of swinging up and down inequality, crushing force is also different, makes the palate plate wearing and tearing very inhomogeneous, and the charging of letter pendulum breaker has the overflow situation to take place, the physical pendulum breaker then is prone to the discharge gate phenomenon of blocking, this has just restricted the raising of output to a certain extent, in order to increase output, has only the eccentric throw that increases eccentric shaft, this has just correspondingly reduced crushing force, and its energy consumption is increased.
Order of the present utility model provides a kind of palate formula breaker that improved.The palate formula breaker of original single crank mechanism is changed into the palate formula breaker of double-crank mechanism, make the moving palate plate amount of swinging up and down in the device identical, stressed even, it is basic identical to wear and tear, and charging and discharge effect have been strengthened, being convenient to eccentric shaft increases rotating speed and dwindles eccentric throw, has improved crushing force effectively, improves crushing effect and cuts down the consumption of energy.
Technical solution of the present utility model is: this palate formula breaker is mainly by the active eccentric shaft, driven eccentric shaft, moving palate (connecting rod) plate, fixedly composition such as palate plate.By in two collars up and down that are loaded on the moving palate (connecting rod), the eccentric throw of this two eccentric shaft is identical respectively for two eccentric shafts, and assembly direction is identical, rotates with speed in the same way.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Accompanying drawing is the schematic diagram of novel palate formula breaker.
(1) eccentric shaft initiatively wherein; (2) driven eccentric shaft; (3) moving palate (connecting rod) plate; (4) fixing palate plate.
As shown in the figure: by active eccentric shaft (1), driven eccentric shaft (2), moving palate (connecting rod) plate (3) is formed double-crank mechanism.Prime mover drives active eccentric shaft (1) through belt transmission (not marking among the figure), rotates around fixing point A1, and at this moment driven eccentric shaft (2) is promptly around fixing point A2 work and initiatively eccentric shaft speed rotation together in the same way.Because the eccentric throw of two eccentric shafts is identical, assembly direction is identical, so moving palate plate is done the top Planar Compound motion identical with the bottom oscillating quantity, when making it periodically and push fixedly palate plate to, the time and leave, thereby the ore reduction between two palate plates, broken qualified ore is discharged from the bottom by the effect of the compound motion of gravity and moving palate, finishes crushing operation.In order to overcome the uncertain of driven member in the parallelogram lindage (driven eccentric shaft 2) rotation direction and to strengthen the even of moving palate crushing force, the utility model can also be handled by following two kinds of forms: adorn anti-reverse friction ratcher on (one) driven eccentric shaft 2; (2) initiatively eccentric shaft 1 drives driven eccentric shaft 2 and the speed rotation together in the same way of its do by chain drive or gear drive.
The utility model compared with the prior art, its advantage is:
(1) to have changed existing palate formula breaker moving palate plate oscillating quantity inequality up and down for the utility model, the pattern of discontinuity, make the moving palate plate oscillating quantity identical up and down, stressed even, when eccentric shaft rotates by counter clockwise direction, moving palate plate is being done the laterally reciprocating while of extruding, and makes elliptical motion up and down.This compound motion of moving palate plate is not only finished the extruding to ore, but also has strengthened charging and discharge effect, makes its charging can overflow, and discharge is difficult for stopping up, and is convenient to improve the rotating speed of eccentric shaft, increases the swing speed of moving palate plate, increases output.Like this, the eccentric throw of eccentric shaft just can be littler than the eccentric throw of the eccentric shaft of the old-fashioned palate formula breaker of same size, increases crushing force, strengthened shattering process, improves production capacity, cuts down the consumption of energy, and improves output and quality,
(2) the palate plate serious wear in the palate formula breaker is insoluble problem always, in original palate formula breaker palate plate wearing and tearing extremely inhomogeneous be a big reason that increases the palate plate waste.The wearing and tearing of the utility model palate plate evenly greatly reduce the palate plate wearing and tearing of specific yield, have reduced broken cost.
(3) maximum crushing force all is vertically to act on fixedly on the palate plate and moving palate plate in palate formula breaker, and the position of its application point is in the palate plate middle part basically.Active eccentric shaft of the present utility model is set to the palate plate middle part, all is better than original device from every side, also can improve the stability of whole device in addition.
In a word, this device only needs to change the suspended axle in original palate formula breaker into driven eccentric shaft, adorns the anti-reverse ratchet mechanism of a cover, cancelled original bracket, one increases one subtracts, unlike original palate formula breaker complexity, manufacturing cost can not increase too much yet, but performance is better than original palate formula breaker.
Claims (3)
1, a kind of novel palate formula breaker, comprise initiatively eccentric shaft, driven eccentric shaft, moving palate plate, fixing palate plate, feature of the present utility model is that two eccentric shafts are respectively by in two collars up and down that are loaded on the moving palate, the eccentric throw of two eccentric shafts is identical, assembly direction is identical, in the same way with the speed rotation.
2, device according to claim 1 is characterized in that the axle head of driven eccentric shaft can be equipped with anti-reverse ratchet mechanism.
3, device according to claim 1 is characterized in that initiatively eccentric shaft can drive driven eccentric shaft work in the same way with the speed rotation by gear drive or chain drive.
