Abstract
The utility model discloses a jaw crusher which comprises a fixed jaw, a movable jaw, a wrist plate and a pull rod, wherein the wrist plate and the pull rod are connected with the lower portion of the movable jaw, the upper end of the movable jaw is fixedly connected with a moving jaw portion which is connected with an eccentric shaft, crushing teeth are respectively arranged on surfaces of the fixed jaw and the movable jaw, the density of the crushing teeth is gradually increased from top to bottom, and the sizes of the crushing teeth are gradually decreased from top to bottom. The sections of the crushing teeth are triangles, the length of the crushing teeth is similar to the width of the foxed jaw and the width of the movable jaw, and the crushing teeth are horizontally arranged on the surface of the fixed jaw and the surface of the movable jaw. According to the jaw crusher, the crushing teeth, larger in sizes and smaller in densities, on the upper portion of the fixed jaw and the upper portion of the movable jaw are used for crushing bigger material blocks; and the crushing teeth, smaller in sizes and larger in densities, on the lower portion of the fixed jaw and the upper portion of the movable jaw are used for crushing smaller material blocks.
Description
Technical field
The utility model is about a kind of disintegrating machine, espespecially a kind of jaw crusher.
Background technology
Jaw crusher, be commonly called as jaw broken, by moving jaw and two jaws of quiet jaw, forms crusher chamber, two jaw movements of simulated animal and complete the disintegrating machine of material crushing operation.Be widely used in the medium size fragmentation of various ores and bulk materials in the industries such as mine, smelting, building materials, highway, railway, water conservancy and chemical industry.The working portion of jaw crusher is two jaws, the one, fixed jaw (determining jaw), vertical (or flare is omited in upper end) is fixed on the body antetheca, and another is sewing jaw (moving jaw), inclined position, form up big and down small crusher chamber (working chamber) with fixed jaw.Sewing jaw is done periodic reciprocating motion facing to fixed jaw, the time and separate, the time and close.In the time of separately, material enters crusher chamber, and finished product draws off from bottom; Near the time, make to be contained in two blocks of materials between jaw and be squeezed, bending and slabbing action and fragmentation.Move jaw during work and determine the rubbing action that jaw bears huge crushing force and material, easily grinding away, in order to protect jaw, generally on moving jaw and the surface of determining jaw, wear-resisting liner plate being installed, this liner plate is called again crushing shell.Its crushing effect in the pyrite cinder shattering process is general.
Summary of the invention
The purpose of this utility model is to provide a kind of jaw crusher, and this device is suitable for the pyrite cinder fragmentation, and crushing effect is outstanding.
Jaw crusher of the present utility model, comprise fixed jaw, sewing jaw, the bracket and the pull bar that with described sewing jaw bottom, are connected; The sewing jaw upper end is fixedly connected with moving jaw section, and described moving jaw section connects eccentric shaft, and described fixed jaw and sewing jaw surface are respectively arranged with crushing teeth, and the density of crushing teeth increases from top to bottom gradually, and the size of crushing teeth reduces from top to bottom gradually.
As optimization, described crushing teeth cross section is triangle, and length approaches with fixed jaw and sewing jaw width, is horizontally installed on fixed jaw and sewing jaw surface.
Jaw crusher of the present utility model, the crushing teeth size on fixed jaw and sewing jaw top is larger, density less for fragmentation than the aniseed piece, the crushing teeth size of fixed jaw and sewing jaw bottom is less, density is larger, the less fragment for fragmentation.
The accompanying drawing explanation
Fig. 1 is the structural representation of the described jaw crusher of embodiment.
The specific embodiment
Introduce in detail embodiment of the present utility model below in conjunction with accompanying drawing.
Jaw crusher, as shown in Figure 1, comprise fixed jaw 1, sewing jaw 2, the bracket 3 and the pull bar 4 that with junction, sewing jaw bottom, are connected; An other end of bracket 3 and pull bar 4 is connected adjusting seat 8, sewing jaw 2 upper ends are fixedly connected with the jaw section 6 of moving, move jaw section 6 and connect eccentric shafts 5, fixed jaw 1 and sewing jaw 2 surfaces are respectively arranged with crushing teeth 7, the density of crushing teeth 7 increases from top to bottom gradually, and the size of crushing teeth 7 reduces from top to bottom gradually.Described crushing teeth 7 cross sections are triangle, and length approaches with fixed jaw 1 and sewing jaw 2 width, is horizontally installed on fixed jaw 1 and sewing jaw 2 surfaces.
Jaw crusher of the present utility model, the crushing teeth size on fixed jaw and sewing jaw top is larger, density less for fragmentation than the aniseed piece, the crushing teeth size of fixed jaw and sewing jaw bottom is less, density is larger, the less fragment for fragmentation.
Claims (2)
1. a jaw crusher, comprise fixed jaw, sewing jaw, the bracket and the pull bar that with described sewing jaw bottom, are connected; The sewing jaw upper end is fixedly connected with moving jaw section, and described moving jaw section connects eccentric shaft; It is characterized in that described fixed jaw and sewing jaw surface are respectively arranged with crushing teeth, the density of crushing teeth increases from top to bottom gradually, and the size of crushing teeth reduces from top to bottom gradually.
2. jaw crusher according to claim 1, is characterized in that described crushing teeth cross section is triangle, and length approaches with fixed jaw and sewing jaw width, is horizontally installed on fixed jaw and sewing jaw surface.
