Abstract
The utility model provides a jaw crusher supporting board additionally provided with replaceable liners at end heads. The bulb-shaped replaceable liners (1) are sleeved at the both end heads of the supporting board (3); pin holes are respectively formed in the inner sides of the liners (1) and the end heads of the supporting board; and the liners (1) are linked with the supporting board (3) through cylindrical pins (2). The jaw crusher supporting board additionally provided with the replaceable liners at the end heads, provided by the utility model, has the advantages that the weight is light, the dismounting is convenient, the end heads are difficult to wear, and the condition of frequently replacing the entire supporting board is not required; and the manufacturing cost and the cost spent on the use of the jaw crusher by a user can be reduced.
Description
Technical field
The utility model relates to a kind of fagging technical field of structures of jaw crusher.
Background technology
The fagging of jaw crusher, being commonly called as safeguard, is that its effect has two not by one of consumable accessory of everybody concern, the one, to the swing support that the jaw arm of doing complicated swinging extrusion building stones is close at any time, the reaction force that the jaw arm is pushed building stones passes to body until the basis is installed; The 2nd, when jaw arm extruding falls into the metal parts reaction force super large of crusher chamber, fagging namely voluntarily bending fracture, destructive power is eliminated immediately, plays the effect of protection equipment.At present the fagging of jaw crusher all design and produce into curve or the straight line of uniform thickness tabular, this fagging in use, three drawbacks of main existence: the one, be to increase contact area, with the wearing and tearing that strengthen lifting surface area and slow down the rotation sliding surface, only has the upper thickness that increases fagging integral body or termination of design, certainly will cause the unnecessary waste of material and increase the moulding difficulty of processing, then increase and make and user's purchase cost; The 2nd, preponderance, fagging installation site own is extremely narrow and small, causes the fagging dismounting to waste time and energy; The 3rd, during the serious wear of the two ends rotation sliding surface of fagging carrying, only have the new part of integral replacing, waste larger, increase subscriber equipment operation expense.In a word, result of use is undesirable.
Summary of the invention
The purpose of this utility model be to provide a kind of comparatively light, be convenient to dismounting, termination not easy to wear, often need not whole replacing, can reduce the jaw crusher fagging of manufacturing and customer using cost.
The purpose of this utility model is achieved by the following technical solution.
A kind of termination installs the jaw crusher fagging of replaceable liner additional, is set with bulb-shaped replaceable liner in the two ends of fagging, is processed with respectively pin-and-hole in the inboard of liner and the termination of fagging, by straight pin liner is connected with fagging.
The utility model is processed with respectively 3～4 pin-and-holes in the inboard of liner and the termination of fagging, and the corresponding straight pin that connects liner and fagging in each termination is 3～4.
Fagging of the present utility model can increase contact area with the crushing jaw arm by increasing the liner area, and the fagging main body needn't be done too thickly, simple in structure, lightweight, and assembling is also can not change original fitted position, and machine tool can be processed.Use fagging of the present utility model at jaw crusher, mainly realize three effects, the material consumption of first fagging is few, only uses originally about 2/3rds, and the cost of material is low; It two is lightweight, and dismounting is relatively convenient laborsaving; It three is fagging end wears of the present utility model when serious, and a replaceable liner that only needs to change two ends gets final product, and middle part fagging main body is still continued to use original paper, and is cheap, and user's maintenance cost is low.
Further set forth content of the present utility model below in conjunction with Figure of description.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model, connects liner 1 by straight pin 2 at the inboard of liner 1 and the termination difference pin hole processing of fagging at the two ends suit bulb-shaped replaceable liner 1 of fagging 3 with fagging 3.For liner 1 is connected with fagging 3 firmly, usually process respectively 3～4 pin-and-holes in the inboard of liner 1 and the termination of fagging 3, correspondence connects liners 1 and fagging 3 in each termination with 3～4 straight pins.
The utility model fagging does not change original fagging installation dimension and requirement, when replaceable liner 1 serious wear of fagging termination, only need to change replaceable liner 1 or the impaired straight pin 2 of part dismounting at two ends, middle part fagging 3 is still continued to use original paper, can continue to use in the load facility after being assembled into integral body, reduce fagging dismounting maintenance cost.
Claims (2)
1. a termination installs the jaw crusher fagging of replaceable liner additional, it is characterized in that, two ends at fagging (3) is set with bulb-shaped replaceable liner (1), be processed with respectively pin-and-hole in the inboard of liner (1) and the termination of fagging, by straight pin (2) liner (1) connected with fagging (3).
2. a kind of termination according to claim 1 installs the jaw crusher fagging of replaceable liner additional, it is characterized in that, be processed with respectively 3～4 pin-and-holes in the inboard of liner (1) and the termination of fagging, the corresponding straight pin (2) that connects liner (1) and fagging (3) in each termination is 3～4.
