Abstract
A kind of wear resistant bar, be made up of rod body and wear-resistant block, rod body is provided with projections/grooves, and wear-resistant block is provided with corresponding groove/land.Wear-resistant block material is ceramic material or wear-resisting alloy steel.Projection is that dovetail shaped is protruding, and groove is the dovetail shaped groove that matching size closes.This rod enormously simplify the structure of wear resistant bar, has that structure is simple, processing and the little advantage of installation difficulty by rod body and wear-resistant block by the rod that grafting forms; The size of specially designed dovetail groove had both been convenient to processing, also assures that the needs of bonding strength between body and wear-resistant block; The wear-resistant block that ceramic material is made ensure that the wearability that rod is enough.
Description
Technical field
The utility model relates to material sieving technology field, especially relates to the abrasion-resistant grate bar on a kind of material screening.
Background technology
Vibratory sieve in mine, the field such as coal, metallurgy is widely used.Easily there is the disadvantage that compass screen surface blocks in the vibratory sieve that the compass screen surface of vibratory sieve of rod sieve structure overcomes mesh screen structure, and vibration efficiency is high, screening effect is good, obtains the favor of people.In conventional art, grating material is general steel alloy, and abrasion resistant effect is poor.
Authorization Notice No. is disclose a kind of grating in the patent of invention of CN1169631C; this grating comprises and has some strength and flexible grating muscle; elastic protective layer is with, setting-in or be bonded with the wearing layer of hard on the upper end face of elastic protective layer in the outside fixed packet of grating muscle.Wherein elastic protective layer is made up of elastomeric material, and elastic wear-resisting layer shape is multiple tablet or little arc, and wearing layer material is pottery, carbide alloy or cast stone.This kind of grating take into account the requirement of wear-resisting type when designing, the wearing layer that multiple tablet or little arc are formed ensure that wearing layer is being more crashed to pieces with being sized in material impacting, extends the service life of grating.But, tablet or between little arc and elastic protective layer faying face less, do not form mechanical annexation, therefore in use wearing layer easily comes off, thus elastic protective layer is directly exposed, and exacerbates the wearing and tearing of grating.
Authorization Notice No. is disclose a kind of abrasion-resistant grate bar in the utility model patent of CN201333444Y, this grating is provided with base layer and wear-resistant composite bed successively on rod, connecting hole is had on wear-resistant composite bed, by the macromolecular material identical with base layer of filling in connecting hole by base layer and wear-resistant composite bed formation as a whole, wear-resistant composite bedly select ceramic material.This rod is by the setting of connecting hole, efficiently solve the problem that composite bed among the course of work comes off, extend the service life of rod, but the ceramic thin film be compounded on rod takes up room larger, macromolecular material at high temperature its adhesive property sharply declines, and finally causes wear-resistant composite bed peeling off.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming existed in prior art, there is provided that a kind of structure is simple, the wear resistant bar of long service life, the technical scheme adopted is: a kind of wear resistant bar, it is characterized in that: described rod is made up of rod body and wear-resistant block, described rod body is provided with projections/grooves, and wear-resistant block is provided with corresponding groove/land.
Technical characteristic of the present utility model also has: described wear-resistant block material is ceramic material or wear-resisting alloy steel.
Technical characteristic of the present utility model also has: described projection is that dovetail shaped is protruding, and described groove is the dovetail shaped groove that matching size closes.
Technical characteristic of the present utility model also has: described dovetail shaped projection is that strip dovetail shaped is protruding, and described dovetail shaped groove is strip dovetail shaped groove.
Technical characteristic of the present utility model also has: described dovetail shaped narrow hem width degree that is protruding or dovetail shaped groove is 10-20mm, and broadside width is 15-25mm, is highly 5-15mm.
Technical characteristic of the present utility model also has: described dovetail shaped narrow hem width degree that is protruding or dovetail shaped groove is 10mm, and broadside width is 15mm, is highly 5mm.
The beneficial effects of the utility model are: this rod enormously simplify the structure of wear resistant bar, have that structure is simple, processing and the little advantage of installation difficulty by rod body and wear-resistant block by the rod that grafting forms; The size of specially designed strip dovetail groove had both been convenient to processing, also assures that the bonding strength between body and wear-resistant block; The wear-resistant block that ceramic material is made ensure that the wearability that rod is enough.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model embodiment one structural representation, accompanying drawing 2 is left views of accompanying drawing 1, accompanying drawing 3 is the utility model embodiment two structural representations, accompanying drawing 4 is left views of accompanying drawing 3, accompanying drawing 5 is the utility model embodiment three structural representations, accompanying drawing 6 is left views of accompanying drawing 5, and wherein 1 is rod body, and 2 is wear-resistant blocks.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.The utility model discloses a kind of wear resistant bar, this rod is made up of rod body 1 and wear-resistant block 2, and rod body 1 is provided with projections/grooves, and wear-resistant block 2 is provided with corresponding groove/land.
In order to ensure the wearability of rod, be ceramic material or wear-resisting alloy steel at the material of the wear-resistant block 2 of rod body 1 upper end.
In order to realize the good combination of rod body 1 and wear-resistant block 2, projection is that dovetail shaped is protruding, and groove is the dovetail shaped groove that matching size closes.
Preferably, the dovetail shaped projection in the utility model is that strip dovetail shaped is protruding, and dovetail shaped groove is strip dovetail shaped groove.
Obtain after test of many times, dovetail shaped narrow hem width degree that is protruding or dovetail shaped groove is 10-20mm, and broadside width is 15-25mm, is highly 5-15mm.When dovetail shaped is protruding or the narrow hem width degree of dovetail shaped groove is 10mm, broadside width is 15mm, when being highly 5mm, this rod has good implementation result.
During combination, bonding agent can be smeared at groove and protruding junction.
The shape of the rod after combination is not limit, and can be U-shaped, as shown in embodiment one; Also can be square or rectangle, as shown in embodiment two; Also can be circle, as shown in embodiment three, certainly also can be other shapes.
Conveniently connect, the length of the groove that rod body is processed generally can be made to be greater than the length of wear-resistant block projection.
Certainly; above-mentioned explanation is not limitation of the utility model; the utility model is also not limited only to above-mentioned citing, the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also belongs to protection domain of the present utility model.
