Abstract
The utility model discloses a kind of plate hammer for crusher, belong to disintegrating machine and manufacture field.It comprises bar main body (1) and plug (2), it is characterized in that, is also included in the upper strip enclosed mass (3) arranged along bar main body lower end working face (4); The cross section of described strip enclosed mass (3) is trapezoidal or triangle, and described bar main body (1) is for rectangular-shaped.By arranging strip enclosed mass technical characteristic, overcome the defects such as existing plate hammer for crusher wearability and intensity, realize the feature of high-wearing feature and high strength, by the setting to reinforcement, and the angle between strip enclosed mass and bar main body lower end working face, achieve plate hammer for crusher service efficiency higher.
Description
Technical field
The utility model relates to a kind of bar, especially relates to a kind of plate hammer for crusher.
Background technology
Impact breaker has that structure is simple, the ratio of reduction is large, energy consumption is low, output is high, lightweight, broken after finished product in cube body etc. advantage, be widely used in the industries such as various ore reduction, railway, highway, the energy, cement, chemical industry, building.
As shown in Figure 1, existing plate hammer for crusher is strip, and the operation of impact breaker utilizes the high speed impact of bar and the rebound effect of counterpunch board, makes material be subject to the machinery of repeated stock and fragmentation.Bar is packed on the rotor of High Rotation Speed, and arranges some pieces of impact flat hammers along crusher chamber by different angles.The first time being first subject to bar when material enters the active region of bar impacts and primary crushing, and obtains kinetic energy simultaneously, and high-speed punching is to counterpunch board.After material and counterpunch board collide fragmentation again, be reflected back to the active region of bar, be again subject to the impact of bar.So repeatedly carry out, until be fractured into required granularity and discharge outside machine.But because bar very easily weares and teares, it is also restricted in the application of hard material fragmentation, be commonly used to coarse crushing, in hard following brittle material in broken or fine stone lime stone, coal, calcium carbide, quartz, dolomite, iron sulfide ore, gypsum and industrial chemicals etc.
Because the ratio of reduction of impact breaker is quite large, so the height that consumable accessory maintenance cost is suitable, the particularly bar of runner assembly, even the utilization rate of the bar of existing impact breaker also only has about 50%, cause very large waste.And the service life of bar is relatively short.How project organization is more reasonable, and materials'use is more saved, and installs more convenient, and the bar of longer service life is the major issue that current ore reduction machinery manufactures and designs.
Chinese Patent Application No.: 201320847307.6, patent name: board hammer structure of impact crusher, file discloses a kind of board hammer structure of impact crusher, there is bar body, its special character is provided with by many main muscle in bar body and encloses the bar-mat reinforcement that muscle forms, a described main muscle point front two rows is arranged in parallel, and is fastenedly connected and is integrated between adjacent main muscle by enclosing muscle.This utility model, by being provided with by main muscle in bar body and enclosing the bar-mat reinforcement and bar body cast solid that muscle forms, realizes wear-resisting technique effect, but reinforcement is understood and directly be contacted with material aborning, weares and teares comparatively serious.
Utility model content
1. the utility model technical problem that will solve
For the deficiency of above existing plate hammer for crusher, the purpose of this utility model is to provide a kind of plate hammer for crusher, by arranging the technical characteristics such as strip enclosed mass, overcoming the defects such as existing plate hammer for crusher wearability and intensity, realizing the feature of high-wearing feature and high strength.
2. technical scheme
A kind of plate hammer for crusher, it comprises bar main body and plug and is also included in strip enclosed mass along bar main body lower end working face is arranged; The cross section of described strip enclosed mass is trapezoidal or triangle.Described bar main body is rectangular-shaped.
As optimal technical scheme of the present utility model, described plug is triangular shape plug, and the angle between the both sides of described triangular shape plug is 126 °.
As optimal technical scheme of the present utility model, described bar main body is provided with reinforcement, and waling and cross reinforcing are mutually vertical.
As optimal technical scheme of the present utility model, described reinforcement diameter is 8mm.
As optimal technical scheme of the present utility model, the angle between described strip enclosed mass and bar main body lower end working face is 135 °.
3. beneficial effect
A kind of plate hammer for crusher of the utility model, by arranging strip enclosed mass technical characteristic, overcoming the defects such as existing plate hammer for crusher wearability and intensity, realizing the feature of high-wearing feature and high strength, also improve the service life of workpiece simultaneously.
By the setting to reinforcement, and the angle between strip enclosed mass and bar main body lower end working face, achieve plate hammer for crusher service efficiency higher, intensity is higher, and the life-span of use is significantly improved far away.
