Abstract

The wear rib for being not less than depth of groove in several rectangular recess, groove filled with thickness has been dug on a kind of disintegrating machine liner plate, including plate body, the working face of described plate body.The utility model uses split-type structural, by the part that rubs and it will be often separately from other sections open in liner plate, it is divided into plate body and wear rib, it is made for wear rib of the material of high cost, the amount come into operation of high low cost materials can so be reduced, so as to reduce cost, use Split type structure simultaneously, it can only need to change wear rib when wear rib weares and teares, plate body can be continuing with, on the one hand it is easy to produce wear rib in batches, on the other hand avoids the plate body waste of part such as need not wear and tear and use, so as to further save cost.

Description

A kind of disintegrating machine liner plate

Technical field

The utility model is related to a kind of breaking device, more particularly, to a kind of disintegrating machine liner plate.

Background technology

Liner plate is one of accessory of disintegrating machine, is mainly used to protect broken machine drum body, abrasion is easier, in some cycles It is interior, it is necessary to be changed, the service efficiency of equipment otherwise can be reduced, increases the load of machine, yield is reduced.In jaw crusher In liner plate, fixed liner plate (tooth plate), dynamic jaw liner plate (tooth plate) and two side plates (backplate) are easiest to abrasion.

Liner plate increases the service life outer, it is often more important that due to its shape of working surface except the broken machine drum body of protection Difference, directly influences grinding efficiency and ability, ore grinding energy consumption, the loss of medium and liner plate, the DYNAMIC DISTRIBUTION of medium etc..

In order to improve the service life of liner plate, using the manganese steel containing manganese more than 12% more preferably, that conventional is ZGMn13 to material. The toughness of manganese steel is preferable, although not high hardness is about 210HB, but because the characteristics of having cold work hardening, is made in pressure Can constantly it be reinforced under, therefore constantly abrasion is continually strengthened again at work, is just scrapped until wearing up to use.And compare For potassium steel, high chrome alloy steel effect has higher wearability, but the cost of high chrome alloy steel is too high, it is impossible to a large amount of Use.

Utility model content

The purpose of this utility model is to be the existing liner plate of solution because high-abrasive material cost is high, it is impossible to a large amount of using so as to use The material substitution of low cost, so as to cause the problem of liner plate service life is low, there is provided a kind of disintegrating machine liner plate.

The utility model is solves the deficiency of above-mentioned technical problem, and the technical scheme used is：

Several rectangular recess have been dug on a kind of disintegrating machine liner plate, including plate body, the working face of described plate body, it is recessed Between being not less than filled with thickness in groove in the wear rib of depth of groove, one side of the wear rib away from groove from one end to the other end etc. Away from setting several boss, the boss is to offer through hole, boss on even number, the wear rib between two boss It is formed in one structure with wear rib, the material that wear rib and boss are more than plate body wearability by wearability is made, in through hole Fixing screws are equipped with, wear rib is fixed in the groove on plate body by fixing screws.

Described plate body is made of potassium steel.

Described wear rib and boss is made of high chrome alloy steel.

The beneficial effects of the utility model are：The utility model uses split-type structural, by what is often rubbed in liner plate Part and it is separately from other sections out, that is, is divided into plate body and wear rib, is made, so may be used of the material of high cost for wear rib To reduce the amount come into operation of high low cost materials, so that cost is reduced, while using Split type structure, can be ground in wear rib Only need to change wear rib during damage, plate body can be continuing with, be on the one hand easy to produce wear rib in batches, on the other hand avoid The plate body waste of part such as need not wear and tear is used, so as to further save cost.

Embodiment

Shown in figure, embodiment is as follows：

Several rectangular recess have been dug on a kind of disintegrating machine liner plate, including plate body 2, the working face of described plate body 2, It is not less than the wear rib 1 of depth of groove in groove filled with thickness, the general thickness using wear rib is more than depth of groove, is Wear rib exposes a part, so as to protect groove to be not damaged by, is easy to the later stage to dismantle wear rib, wear rib 1 when changing wear rib Several boss 101 are set at equal intervals from one end to the other end in one side away from groove, ordinary circumstance lower convex platform is direct Since the edge of wear rib, the coincident of as first convex edge of table and wear rib, it would however also be possible to employ boss is close Inside wear rib, wear rib exposes a part of externally-located, but is designed so as to that the length of wear rib can be caused to increase, by High in the cost of its material, length, which increases some, can increase cost, therefore be not frequently used, and the boss 101 is even number, position Offer through hole 102 on wear rib 1 between two boss 101, boss 101 and wear rib 1 are formed in one structure, boss 101 and wear rib 1 be integrated machine-shaping, wear rib 1 and boss 101 are more than the material of the wearability of plate body 2 by wearability It is made, fixing screws is equipped with through hole 102, wear rib 1 is fixed in the groove on plate body 2 by fixing screws.

Described plate body 2 is made of potassium steel.

Described wear rib 1 and boss 101 are made of high chrome alloy steel.

Technical scheme and embodiment and non-limiting cited by the utility model, with the skill cited by the utility model Art scheme and embodiment are equal or effect same approach is all in the range of the utility model is protected.
