Abstract
The utility model discloses a jaw crusher which comprises a fixed jaw plate, a movable jaw plate, a wrist plate and a pull rod. The wrist plate and the pull rod are connected with the lower portion of the movable jaw plate. A movable jaw part is fixedly connected at the upper end of the movable jaw plate and connected with an eccentric shaft. A material discharging port is formed by a gap on the lower portion of the fixed jaw plate and a gap on the lower portion of the movable jaw plate. A bending part is arranged on the lower portion of the movable jaw plate and faces toward the fixed jaw plate. The bending angle of the bending part is 90-110 degrees. Crushing teeth are arranged on the lower portion of the fixed jaw plate, and the direction of the crushing teeth faces toward the bending part. Duo to the facts that the bending part is arranged on the lower portion of the movable jaw plate and faces toward the fixed jaw plate and the crushing teeth are arranged on the lower portion of the fixed jaw plate, long strip-shaped crush stuff falling into the bending part is extruded by the crushing teeth to facilitate that the long strip-shaped crush stuff is further crushed and the crushing effect is improved.
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.Generally the passage between two jaws is beeline channel, not good enough for the broken thing crushing effect of elongate in shape.
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 broken thing fragmentation of elongate in shape, 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; The gap of fixed jaw bottom and sewing jaw bottom forms discharging opening, and described sewing jaw bottom is provided with the bending part towards fixed jaw, and the bending angle of bending part is 90 °～110 °.
As optimization, described fixed jaw bottom is provided with crushing teeth, and the direction of crushing teeth is towards described bending part.
Jaw crusher of the present utility model, the sewing jaw bottom is provided with the bending part towards fixed jaw, and the fixed jaw bottom is provided with crushing teeth, drops into the broken thing of the elongate in shape of bending part, through the crushing teeth extruding.Contribute to the broken thing of elongate in shape is carried out to further fragmentation, improve crushing effect.
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, and sewing jaw 2 upper ends are fixedly connected with moving jaw section 6, and described moving jaw section 6 connects eccentric shafts 5; The gap of fixed jaw 1 bottom and sewing jaw 2 bottoms forms discharging opening, and sewing jaw 1 bottom is provided with the bending part 9 towards fixed jaw 2, and the bending angle of bending part 9 is 90 °～110 °.Fixed jaw 1 bottom is provided with crushing teeth 7, and the direction of crushing teeth 7 is towards described bending part 9.
Jaw crusher of the present utility model, sewing jaw 2 bottoms are provided with the bending part 9 towards fixed jaw 1, and fixed jaw 1 bottom is provided with crushing teeth 7, drops into the broken thing of the elongate in shape of bending part 9, through crushing teeth 7 extruding.Contribute to the broken thing of elongate in shape is carried out to further fragmentation, improve crushing effect.
