Abstract
The invention discloses an opening adjustment and safety device of a jaw crusher. The device comprises a rack (1) and a movable jaw plate (2) of the jaw crusher, wherein the upper end of the movable jaw plate (2) is connected with the rack (1) through a hinge; a hydraulic safety device is hinged between the lower end of the movable jaw plate (2) and the rack (1). The hydraulic safety device is adopted by the safety device of the jaw crusher, is compact and is reliable in work, and non-crushed objects can be automatically discharged when the objects enter a crushing cavity and the movable jaw is automatically reset without stopping, so the increased stress of the machine is small, generally 10 percent; about 30 percent of stress of the machine is increased by the conventional wrist plate safety device.
Description
Technical field
The present invention relates to a kind of opening of jaw crusher is adjusted and safety, belong to jaw crusher technical field.
Background technology
Jaw crusher is commonly called as Hubei Province and breaks, and by the two pieces of jaws in dynamic Hubei Province and quiet jaw crusher chamber is constituted, and simulates two jaw movements of animal
And complete the disintegrating machine of material crushing operation.It is widely used in the row such as mine, smelting, building materials, highway, railway, water conservancy and chemical industry
In industry.Jaw crusher completes dynamic Jaw plate and moves back and forth by motor belt motor dynamic crankshaft, using dynamic squeezing between Jaw plate and quiet Jaw plate
Pressing to complete the broken of material, but move Jaw plate in use can be worn with quiet Jaw plate, the size of the material that is so broken
Will change, be the size for ensureing broken material, jaw crusher all has opening regulating mechanism, existing opening regulating mechanism
Realized by changing dynamic Jaw plate, its regulative mode is that it adjusts every time opening and wants whole machine using pad adjustment opening
Quit work, mode is bracket seat to be backed down with screw rod be allowed to be separated with pad, take out or increase pad so as to come realize opening
Size, the regulative mode is very inconvenient, can only realize that level is adjusted, and this kind of method wastes substantial amounts of time and manpower.
Simultaneously jaw crusher to prevent non-broken material from causing to damage to equipment in shattering process, break by existing jaw
Broken machine is equipped with safety, and the device at present more adopts bracket（Cast iron materials）, hole is opened up above, to reduce section intensity,
After non-broken material falls into, machine exceedes normal duty, ruptures immediately, makes disintegrating machine quit work, so as to avoid machine master
Want parts to damage, though the structure can preferably play safety effect, suffer from the drawback that：1）It is necessary after bracket fracture
Work is shut down, can be worked after replacing；2）Because bracket is casting material, the defect such as inevitable pore, trachoma makes foundry goods strong
Degree changes, and disintegrating machine is not reaching to the value beyond load when work toward contact, and bracket begins to fracture, affects
Equipment normally runs.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of easy to adjust, quick, safety safety coefficient standard that is open
The opening of true jaw crusher is adjusted and safety, can overcome the deficiencies in the prior art.
Technical scheme：The opening of jaw crusher is adjusted and safety, and it includes the machine of jaw crusher
Frame and moving jaw plate, the upper end of dynamic Jaw plate is connected by hinge with frame, and between the lower end of dynamic Jaw plate and frame hydraulic pressure is hinged with
Safety.
The opening of above-mentioned jaw crusher is adjusted and safety are to be connected in dynamic Jaw plate and frame and be hinged
Seat board, described hydrostatic safety device includes oil cylinder, and on the cylinder body and piston rod of oil cylinder articulated slab, articulated slab are connected to
It is connected by hinge bar with seat board is hinged.
The opening of aforesaid jaw crusher is adjusted and safety are, the cylinder ends of oil cylinder and the end of piston rod are logical
Cross the stage casing for being bolted to articulated slab, articulated slab is with to be hinged seat board by the position position that hinge bar is connected be articulated slab and be hinged
The two ends of seat board.
The opening of aforesaid jaw crusher is adjusted and safety are, hinge bar by T-shaped threaded rod and horizon bar structure
Into threaded rod is connected to the center of horizon bar；It is being hinged a pair of the hooks that are respectively arranged at two ends with of seat board, the level of hinge bar
Bar is connected on hook, threaded rod is connected with hold-down bolt through after the connector on articulated slab and realizes being hinged.
The opening of aforesaid jaw crusher is adjusted and safety are that spring, bullet are cased with the threaded rod of hinge bar
Spring was located between the connector of articulated slab and hold-down bolt.The opening direction for being arranged on a pair of hooks for being hinged seat board two ends is anti-
To.
Compared with the prior art, this jaw crusher safety device adopts hydrostatic safety device, and hydrostatic safety device is compact,
Reliable operation, non-fragment can be automatically drained out into crusher chamber and move jaw and automatically reset, without stopping, the stress for increasing machine
It is little, generally 10%, and traditional bracket safety make machine increase by 30% or so stress.And adjusted using oil cylinder, very well
The many disadvantages for avoiding being open when adjusting, do not need shutdown operation when adjusting opening, adjusting openings of sizes need to only adjust oil cylinder
Stroke, with efficiently fast and accurately advantage.
Simultaneously because of the limited space between the dynamic Jaw plate and frame of jaw crusher, horizontally disposed using oil cylinder is adjusted
Saving need to just meet size, intensity requirement and its deflection angle of its stroke, be to adjust to require more than meeting, of the invention by oil cylinder
Two ends employ articulated structure, while during being hinged, if be hinged using the end of cylinder body and expansion link, its
The stroke of oil cylinder will significantly be limited, it is impossible to meet industrial requirements, Gu employs the structure that two ends are hinged, if hinge point is straight
Connect using being rigidly connected, when broken material, unbalance stress will affect oil cylinder service life, and the present invention can using spring straining
To compensate the impact that crushing force inequality is caused by deflection, increase the service life of oil cylinder.
