Description
Technical field
The utility model is related to a kind of concrete mixer abrasion-proof structure.
Background technology
Concrete pump be it is a kind of hoist or distant place delivering concrete plant equipment, in concrete delivery service, mix
Concrete is pressed onto in delivery pipe by the conveying cylinder of solidifying soil pump by the cooperation of cheater plate and cut ring, and concrete is sent to by delivery pipe
Predetermined position.
During delivering concrete, cheater plate and cut ring are a pair of wear parts used cooperatively.Cheater plate has
Two material transport holes and a cut surface；Cut ring has a material transport hole and a cut surface；In concrete pump delivering concrete
During, the cut surface of cut ring is engaged with the cut surface of cheater plate, and cut ring is simultaneously slided, contraposition along the cut surface of cheater plate
Cut in the concrete of cheater plate conveying orifice part, concrete produces the cut surface and the cut surface of cheater plate to cut ring
Reaction force；So as to which the operating environment of concrete pump requires that the cut surface of cut ring and cheater plate will can bear larger
Concrete reaction force；In addition, during concrete pump delivering concrete, the conveying wall surface of the hole of cheater plate and cut ring also will
Bear corrosion, wear, the impact of concrete；This also requires that conveying wall surface of the hole will have higher anti-wear performance；In a word, cut ring
With the working environment very severe of cheater plate, it is desirable to which the working face (including cut surface and conveying wall surface of the hole) of the two will have good
Combination property, with higher hardness and toughness, to ensure higher wearability and impact resistance.
For convenience of description, cheater plate or cut ring are referred to wear parts below.
Chinese patent literature CN2433413Y and CN2433234Y individually discloses a kind of structure of wear parts.Patent text
Offering cheater plate disclosed in CN2433413Y includes body, has the overlay cladding fixed with this body phase on conveying wall surface of the hole, in eye
The hard alloy layer of polylith hard alloy composition is welded with the cut surface of runner plate.Patent document CN2433234Y is disclosed to be cut
Ring includes body, also has overlay cladding in the material transport hole of cut ring, also welds and be made up of polylith hard alloy on cut surface
Hard alloy layer.Above-mentioned cheater plate, the defect of cut ring are：Firstth, on working face, between overlay cladding and hard alloy layer
Still part body is exposed in concrete, in using in process, the part body is highly susceptible to abrasion；Secondth,
After expose portion body wear, the root of overlay cladding and hard alloy is exposed in concrete, this allow for overlay cladding and
Hard alloy when being interacted with concrete, be very easy to be broken because being impacted, chip off-falling；3rd, overlay cladding sheet
The hardness of body is low, and wearability is poor, and thinner thickness, and under the souring of concrete, working life is shorter；Particularly cutting
When cutting the stone in ring cutting cutting concrete, shearing, which impacts power, can make the overlay cladding of conveying orifice part burst apart.Therefore, it is above-mentioned resistance to
The anti-wear performance for grinding component working face is relatively low, it is impossible to meet the wearability need that concrete mixer is proposed to wear parts working face
Will.
In view of the above-mentioned problems, Chinese patent literature CN2639555Y and CN2612818Y disclose another wear-resisting portion respectively
In part, the technical scheme, the working face of cut ring or cheater plate, including cut surface and material transport hole inwall are by the hard of integrative-structure
Alloy is covered, so that working face has identical anti-wear performance and wear-resisting intensity, with improve wear parts working face it is whole
Body hardness, improves anti-wear performance, although the technical scheme seem to compensate for Chinese patent literature CN2433413Y with
Problem present in technical scheme described in CN2433234Y, but in actual application, but there is following defect：
Firstth, not enough, impact resistance is relatively low, and wear parts service life is shorter for wear parts working face toughness.For
The hard alloy that soldering is fixed, in use, under the continuation impact of concrete reaction force, hard alloy is shorter
Rupture will be produced in time, causes wear parts to fail.By pouring type fix hard alloy wear parts there is also
Identical the problem of.
Secondth, when cast, soldering and other welding manners fix hard alloy, hard alloy can undergo high thermal change mistake
Journey, makes hard alloy be very easy to produce stress concentration；Moreover, high thermal transformation can cause shadow to the performance of hard alloy
Ring, cause the intensity and hardness of hard alloy to decline, shorten the use time of wear parts.
Above mentioned problem is not only present in the situation as wear body with hard alloy, is making wear-resisting with other high-abrasive materials
During body, there is also above mentioned problem.
In addition, in the technical scheme described in Chinese patent literature CN201486843U, inner surface and the sheet of wear body
The surface of body is engaged, and in the mode that this inner surface coordinates, still has a surface hardness inadequate in body, it is impossible to completely to reach
To wearability.
In a word, prior art can not ensure the hardness and toughness of wear parts working face simultaneously, so as to can not ensure work
The anti-wear performance and impact resistance in face, cause the service life of wear parts shorter, and existing manufacture wear parts
Method can also damage the performance of wear parts and the performance of wear body.
The content of the invention
The purpose of this utility model is to provide a kind of concrete mixer abrasion-proof structure, and this abrasion-proof structure mainly employs spill
Full alloy cut ring, this cut ring coats base end, and with reference to more closely, while hardness and toughness are improved, service life is more
It is long.
In order to solve the above technical problems, the technical scheme that the utility model is taken is：A kind of wear-resisting knot of concrete mixer
Structure, including：Annular matrix, build-up wear-resistant layer, cut ring, the cut ring are concave；The spill is divided into symmetrical protrusion

In the depressed part C of shape, described matrix ring portion E inside surfacing wearing layers.In this programme, base end is placed in cut ring depression
In portion, concrete mixer cut ring is set to be bound more closely with matrix, in addition, also including：1st, add alloy width and
Sealing, extends the service life of cut ring；2nd, the internal-and external diameter of cut ring uses the traditional overlay cladding of matrix alloy replacing
Technique, adds the anti-wear performance of cut ring, and user measures very big lifting, it is to avoid the frequency of cut ring accessory is changed in increase,
Improve product quality, it is ensured that the normal of equipment is used.
