Abstract
The utility model relates to an improved jaw crusher which comprises a machine foundation, a fixed jaw, a movable jaw and an eccentric-shaft, wherein, a toothed plate of fixed jaw is fixed on the fixed jaw; a toothed plate of movable jaw is fixed on the movable jaw through a coupling bar; side guide plates are arranged on both sides of the movable and fixed jaws; the upper end of the movable jaw is covered on the eccentric-shaft; a bearing housing is arranged between the movable jaw and the eccentric shaft; a coupling hole of the coupling bar of the toothed plate of movable jaw on the movable jaw is arranged on the top of the movable jaw and on the outside of the bearing housing. The utility model has the advantages of that the structure is simple and reasonable, the manufacture of the movable jaw is simplified, and the bearing chamber of the movable jaw has good leak tightness and good operation performance without oil leakage, the service condition of the entire machine is greatly improved, the noise is low, the performance is stable, the effects of electricity saving and energy saving are obvious, thereby being favorable for promotion and application in the areas of mining, building materials, silicates, metallurgy, road construction, chemical industry raw materials and etc, and is especially suited for crushing medium hard materials such as rock, ore and grog of cement works.
Description
Technical field
The utility model jaw crusher is a kind of material crusher tool, is applicable to mine, building materials, silicate, metallurgy, builds the road, the material in field such as chemical industry raw material pulverizes.
Background technology
In the mine, building materials, silicate, metallurgical, build the road, fields such as chemical industry raw material, as cement, pottery, refractory material, fields such as building stones pulverizing, jaw crusher is a kind of size reduction machinery that is widely adopted, it comprises support, decide jaw, moving jaw, eccentric shaft, decide to be fixed with on the jaw and decide the jaw tooth plate, moving jaw tooth plate is fixed on the moving jaw by connecting tightening latch, moving, the both sides of deciding the jaw tooth plate are provided with side guard plate, the upper end of moving jaw is sleeved on the eccentric shaft, is provided with bearing chamber between moving jaw and eccentric shaft, or the like, during work, eccentric shaft drives moving jaw and does periodic reciprocating motion to decide jaw, the time and close, the time and leave.When close, material moving, that decide between the jaw tooth plate is extruded, collides pulverizing, and when leaving, pulverized material draws off from the small powder mouth automatically by own wt.Existing jaw crusher, moving jaw tooth plate is positioned at the top of moving jaw with the connecting hole that is connected tightening latch of moving jaw, make the connection tightening latch that passes pass through bearing chamber, bring difficulty not only for the making of moving jaw, more seriously influenced the normal operation of bearing chamber, also cause the lubricating oil of lubricating bearings to be missed from connecting hole easily, waste lubricating oil has polluted work running environment again.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of improved jaw crusher is provided, and rational in infrastructure, moving jaw bearing chamber good airproof performance, runnability is good, and is oil-proof.
Improved jaw crusher described in the utility model, comprise support, decide jaw, move jaw, eccentric shaft, decide to be fixed with on the jaw and decide the jaw tooth plate, moving jaw tooth plate is fixed on the moving jaw by connecting tightening latch, both sides moving, that decide the jaw tooth plate are provided with side guard plate, and the upper end of moving jaw is sleeved on the eccentric shaft, are provided with bearing chamber between moving jaw and eccentric shaft, its technical essential is that the connecting hole of the connection tightening latch of jaw tooth plate on moving jaw is positioned at the top of moving jaw, preferably is positioned at the outside of bearing chamber.
Improvement of the present utility model has stopped to occur the connecting hole of bottom; avoided the leakage of oil problem of bearing chamber lubricating oil, when connecting hole was positioned at the promptly outer upside in the outside of bearing chamber, structure was ingenious; compact and reasonable; simplify the making of moving jaw, connected tightening latch and needn't pass through bearing chamber, made bearing chamber obtain the complete closed of self; runnability improves; fundamentally solve the leakage of oil problem again, saved lubricating oil, protected environment.
Moving jaw can be casting integrated formula structure, and simple for production, cost is low, and intensity is big.
At this point; with the center line that be higher than eccentric shaft of connecting hole in the height design of moving jaw tooth plate one side; bigger connection space is arranged; when realizing installing at an easy rate again jaw tooth plate top is exceeded and decide the jaw tooth plate; moving jaw and bearing chamber have been protected; the desire comminuting matter of avoiding dropping is pounded moving jaw of damage and bearing chamber; and owing to the supplied materials of desire pulverizing is pulled guide effect than decide the moving jaw tooth plate that the jaw tooth plate exceeds; make the pan feeding that to pulverize obtain making in order to a certain degree; the assurance blanking is unimpeded; avoided plug material card machine phenomenon, safe and reliable.
In the utility model, also can do the adjustment and the improvement of some others, further to improve serviceability, as changing size, the gap of teeth on the tooth plate, to regulate material grinding particle size etc.; The power wheel that drives eccentric shaft can be installed two of symmetry in both sides, so that standby, selects to use according to the place situation when also using for the client, and two power wheels play certain balanced action to the normal operation of eccentric shaft, increase running stability; On support, add the reinforcement gusset, strengthen firm stable; Change the powered pulley size, regulate driving power, reduce the motor configuration, can change into by original 30KW motor and use the 7.5KW motor, cut down the consumption of energy; Or the like.This improves suitable single action jaw, two moving jaw, moves the jaw crusher of jaw more.
As can be seen, the utility model is simple and reasonable, simplified the making of moving jaw, moving jaw bearing chamber good airproof performance, runnability is good, and is oil-proof, and blanking is unimpeded, avoided plug material card machine phenomenon, safe and reliable, improved the complete machine operating position greatly, noise is little, operate steadily, the electricity saving and energy saving effect is obvious, is beneficial to and applies, and is widely used in mine, building materials, silicate, metallurgy, builds the road, field such as chemical industry raw material, suitable especially medium hardness material grinding is as the grog in rock, ore, cement plant etc.
