Technical Field

The utility model relates to a structural improvement mode of crushing machinery, in particular to a jaw plate safety fixing device.

Background

The jaw crusher is a large-scale device which simulates the jaw movement of animals to complete crushing operation, is widely applied to crushing work of large materials in the fields of mining, building materials, building construction, basic road construction, water conservancy, chemical engineering and the like, has higher processing efficiency, the main crushing working parts of the jaw crusher are a movable jaw and a fixed jaw, the movable jaw and the fixed jaw are mutually dislocated to generate shearing force to crush the materials, toothed plates, also called as jaws, are arranged on the movable jaw and the fixed jaw, are consumption abrasion parts, have high hardness, teeth on the working surface to generate huge friction force, the actual working condition is that the two jaws are dislocated to be contacted with the materials, the connection reliability of the jaws determines the service life of the jaws, if the connection strength of the jaws is insufficient, the materials are dislocated with the crusher, cracks are generated, and the service life of the jaws is directly influenced, the jaw plate is fixed in a fixing mode of mounting through bolts, but the bolts are easily exposed outside and directly contact with a processing space, so that the fixed structure is easily abraded, the maintenance and replacement cost is increased, frequent replacement treatment is required, and the processing efficiency is influenced.

Disclosure of Invention

The present invention is directed to overcoming the above-mentioned deficiencies in the prior art and providing a jaw plate safety securing device.

The technical scheme adopted by the utility model for solving the problems is as follows: including jaw and fixed body, the jaw is fixed at jaw breaker vertical perhaps incline direction, and the jaw is fixed on the foundatin plate in the processing passageway of jaw breaker, and the upper portion edge and the lower part edge of jaw press from both sides tight setting and fix on the foundatin plate through the fixed body, the fixed body forms to become the trapezoidal bar structure of rigid cross-section to its inclined plane compresses tightly the side that sets up in the jaw correspondence, the fixed body passes through on the fixed foundatin plate of set screw, and the surface of fixed body is less than the machined surface of jaw, the upper surface of fixed body is smooth surface, opens at the lateral part of fixed body has screw arrangement groove, and set screw arrangement groove passes through screw arrangement groove, and screw arrangement groove is including the narrow groove that corresponds with set screw's spiral surface to and the spiral groove that corresponds with the spiral head, revolves the spiral groove and sets up to the arc and revolves the spiral groove structure, and the clearance between its lateral wall and the spiral head can hold the spanner and rotate wherein, the screw head is tightly pressed in the screwing groove and fixes the fixing body on the foundation plate.

This device is a jaw plate fixed knot constructs for using in jaw breaker, for current fixed knot structure, it is good to have the wearability, the steady quality, the advantage that has good guard action to fixed knot constructs, can improve equipment's life, and reduce the frequency that the accessory was changed in the maintenance of equipment, be favorable to improving the efficiency of processing, increase of production, help improving the economic benefits of enterprise, and can be in the life-span of jaw plate continuous use, improve the utilization ratio to the jaw plate, reduce the accessory consumption, be favorable to improving equipment's quality.

Jaw in this structure is the consumption piece that is used for wearing and tearing processing, need change after wearing and tearing, so need have supporting mounting structure, the upper and lower both edges of jaw that the jaw passes through the fixed body centre gripping, the edge of jaw is the inclined plane, and cooperate the wedge-shaped tight contact structure of clamp of formation of fixed body side, and fix the jaw, the fixed body passes through set screw to be fixed on the foundatin plate, the screw arrangement groove is seted up to the fixed body side direction, set screw side direction enters into in the screw arrangement groove and can twist soon the groove, twist through the spanner and move, realize the fixed effect of screw, set screw does not show at the upper surface of fixed body, the building stones that has reduced crushing process at the in-process of processing are to fixed knot's wearing and tearing, guarantee fixed knot's life.

Furthermore, the back of jaw is pegged graft and is provided with the locating lever, and on the locating lever corresponded the inserting foundatin plate, the jaw corresponded the location on the foundatin plate and fixed through the fixed body. Because the dead weight of jaw board is great, location in installation hoist and mount process is comparatively loaded down with trivial details, carries out the location direction through setting up the locating lever, can improve the positioning accuracy of jaw board, improves the efficiency of installation to reduce wear improves fixed mounting's reliability.

Furthermore, the fixing screw is sleeved with a spring washer, and the spring washer elastically supports in a fixing gap of the fixing screw. The spring washer has elasticity in the pressing force direction, can tightly press the thread gap on the fixing screw, and improves the fixing strength so as to adapt to the vibration working environment in the jaw crusher.

Furthermore, the fixing body is of an integrally cast structure, and the screw placement groove is of a flat opening structure and is directly formed on the surface of the fixing body. The fixing body is molded by casting, and the screw placement groove can be directly molded in a mold for an open structure, so that the integrated structure has good wear resistance and is not easy to deform.

Compared with the prior art, the utility model has the following advantages and effects: this device is a jaw plate fixed knot constructs for using in jaw breaker, for current fixed knot structure, it is good to have the wearability, the steady quality, the advantage that has good guard action to fixed knot constructs, can improve equipment's life, and reduce the frequency that the accessory was changed in the maintenance of equipment, be favorable to improving the efficiency of processing, increase of production, help improving the economic benefits of enterprise, and can be in the life-span of jaw plate continuous use, improve the utilization ratio to the jaw plate, reduce the accessory consumption, be favorable to improving equipment's quality.
