Abstract
The utility model relates to crushing devices used in industries of mines, building materials and capital construction, in particular to an improved movable jaw board of a jaw crusher. A fixed jaw board is installed on the front wall of a crusher rack, an upper end and an lower end of one surface of the movable crusher are formed a Z-shaped structure and correspondingly connected with a V-shaped tank of a movable jaw, the movable jaw board and the movable jaw are fixedly connected by bolts and wedges at the upper end of the movable jaw board, and edges of the upper portion and lower portion of the movable jaw are covered by edges of two outer ends of the Z-shaped structure of the movable jaw board. Due to the fact that the whole lower surface of the movable jaw is covered by the lower end of the movable jaw board, materials are only contacted with the movable jaw board when falling down, so that the movable jaw is not abraded by extrusion of materials, thereby the service life of the movable jaw is greatly prolonged.
Description
Technical field
The utility model relates to the disintegrating apparatus of industries such as being used for mine, building materials, capital construction, particularly a kind of improved jaw crusher sewing jaw.
Background technology
Extensively apply to 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, form crusher chamber by moving Hubei Province and two jaws of quiet jaw, two jaw movements of simulated animal and finish the disintegrating machine of material crushing operation.At present, known jaw crusher such as Fig. 1, its sewing jaw 3 is working portions, is fixed on the moving jaw 4 with bolt 6 and voussoir 5, and fixed jaw 2 is installed on frame 1 antetheca, and the sewing jaw 3 of moving jaw 4 is suspended on the eccentric shaft.The two ends up and down of sewing jaw 3 are V-shaped, as Fig. 4, in the bottom of moving jaw 4 corresponding with it " V " shape groove arranged, and block with sewing jaw 3 thereby will move jaw 4.In use, because after material fell to breaking away from sewing jaw 3, " V " shape groove lower end of moving jaw 4 bottoms still had extruding to material, the lower end of therefore moving jaw 4 is easy to generate wearing and tearing, can not hold sewing jaw 3 during serious wear, moving jaw 4 must be repaired or change.
Summary of the invention
The purpose of this utility model provides a kind ofly can effectively protect moving jaw, improves the jaw crusher sewing jaw in moving jaw life-span.
The purpose of this utility model is achieved in that a kind of improved jaw crusher sewing jaw, the frame antetheca is equipped with fixed jaw, the upper and lower side of sewing jaw one side be " Z " shape structure and with the corresponding connection of " V " shape groove of moving jaw, and the sewing jaw upper end makes sewing jaw fixedly connected with moving jaw by bolt and voussoir, and " Z " shape structure two outer end edges of sewing jaw cover along the edge, top and the bottom that will move jaw.
Another program is to be installed with cover plate in two " V " of sewing jaw shape outer end, and will move edge, the top and the bottom covering of jaw.
Advantage of the present utility model is, because the lower surface of moving jaw is covered by edge, sewing jaw lower end all over, when falling, material all only can contact sewing jaw, can not contact with the bottom of moving jaw, make the jaw can the material extrusion abrasion, thereby because of having improved the life-span of moving jaw widely.
Description of drawings
Fig. 1 is existing jaw crusher structure cut-away view
Fig. 2 is a structure cut-away view of the present utility model
Fig. 3 is that cut-away view is amplified at the A place among Fig. 2
Fig. 4 is the cut-away view of existing sewing jaw 3
Fig. 5 is the cut-away view of sewing jaw 3 of the present utility model
Among the figure: 1. frame, 2. fixed jaw, 3. sewing jaw, 4. moving jaw, 5. voussoir, 6. bolt.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified, referring to Fig. 2 and Fig. 3, a kind of improved jaw crusher sewing jaw, frame 1 antetheca is equipped with fixed jaw 2, the upper and lower side of sewing jaw 3 one side be " Z " shape structure and with the corresponding connection of " V " shape groove of moving jaw 4, and sewing jaw 3 upper ends make sewing jaw 3 fixedly connected with moving jaw 4 by bolt 6 and voussoir 5, and " Z " shape structure two outer end edges of sewing jaw 3 cover along the edge, top and the bottom that will move jaw 4.Referring to Fig. 5, sewing jaw 3 upper and lower sides are long limit, " Z " shape structure outer, and are corresponding with the edge, top and the bottom of moving jaw 4, and the edge that moves jaw 4 can be covered.Referring to Fig. 3, the section after the edge, top and the bottom of sewing jaw 3 upper and lower sides and moving jaw 4 is topped is " Z " shape.
Therefore, being covered owing to the bottom of moving jaw 4 by sewing jaw 3.When material fell, material only can contact with sewing jaw 3, can not touch the bottom of moving jaw 4, thereby reached the moving jaw 4 of protection, prolonged 4 service lifes of moving jaw.
The another kind of embodiment of the utility model is to be installed with cover plate in two " V " of sewing jaw 3 shape outer end, and will move edge, the top and the bottom covering of jaw 4.To protect the edge, top and the bottom that moves jaw 4 not by the material extrusion abrasion.
