Abstract

The utility model discloses a vertical shaft high wear resistance breaking buffer plug in type through head which is composed of a through head, hard alloys and elastic buffer sleeves, wherein the circumference of the cylindrical through head (2) is embedded with a single or a plurality of sheet-shaped hard alloys (3) in a single row, or double rows, or three rows or a plurality of rows, wherein the upper end of the through head (2) is provided with the elastic buffer sleeve (1), and the lower end is provided with the elastic buffer sleeve (4); the circumference of the through head (2) is provided with a triangular anti-rotation bayonet (5). The utility model uses a plurality of rows of alloys to prevent bodies on both sides of each alloy from being worn, and simultaneously guarantees that when part alloys are smashed in a special case, other alloys can also play actions. The installation of the through head uses a plug in type but not a bolt connecting mode, and meantime, a plugging hole is filled by elastic filling materials, so that the alloys on the through head can avoid the impact peak of materials, and the shock resistant and over-iron resistant properties of the alloys are enhanced. With buffer connection, the utility model can use hard alloys with high microhardness to enhance wear resistant property and is suitable for vertical shaft type impact crushers.

Description

The broken high abrasion buffering of vertical shaft plug-in material casting head

Technical field: the utility model relates to vertical shaft type impact crusher material casting head, the broken high abrasion buffering of particularly a kind of vertical shaft plug-in material casting head.

Background technology: vertical shaft type impact crusher is by after accelerating to the high linear speed of 60m/s～80m/s to material, and is broken by collision.Its accelerating rotor is protected from lining owing to forming material; but the impelling mouth at material can not form backing strap; all adopt the material casting head that contains carbide alloy to support; since carbide alloy wearability and the contradiction of impacting bearing property, the key that becomes vertical shaft type impact crusher service life of solution material casting head.

The failure mode of material casting head has at present: 1. organism material wearing and tearing: be subjected to the material wearing and tearing in the both sides of a material casting carbide alloy, alloy exposes, comes off and lost efficacy; 2. the impact that under the above high linear speed of 65m/s, forms of irony foreign material, bulk materials, make a material casting carbide alloy cracked and lost efficacy: 3. the abrasion height of broken material, its microhardness is near the carbide alloy that is adopted, and a material casting carbide alloy weares and teares gradually and lost efficacy; 4. material casting head and the powerful centrifugal force that can not bear being connected of rotor block under the high rotating speed, integral body comes off and lost efficacy.

Summary of the invention: the purpose of this utility model is to provide the broken high abrasion buffering of a kind of vertical shaft plug-in material casting head, utilize this material casting head can prevent the wearing and tearing of alloy both sides body, improve impact resistance and resisted the iron ability, improve its anti-wear performance, reach and improve the material casting purpose in a service life.

Formation of the present utility model: form by material casting head, carbide alloy and elastic buffer cover, on the circumference of cylindrical material casting 2, embed sheet carbide 3, elastic buffer cover 1 is housed in the upper end of material casting 2, elastic buffer cover 4 is equipped with in the lower end, on the circumference of material casting 2 triangle anti-rotation bayonet socket 5 is arranged.

On the circumference of material casting 2, single embedding wall scroll or many strip of sheet carbide alloy 3 also can be double, three rows or many rows embed wall scroll or many strip of sheet carbide alloy 3.

Compared with the prior art, the utility model adopts many row's alloys, prevents the wearing and tearing of alloy both sides body, and when guaranteeing that also alloy part is crashed to pieces under special circumstances simultaneously, other alloy still can play a role; The installation of material casting head is adopted plug-in type but not bolt connecting mode, adopts elastic filler to fill simultaneously in spliced eye, makes the alloy on the material casting head can avoid the material impact peak value, improves impact resistance and resists the iron ability; Because adopted buffering to connect, a material casting alloy then need not too much be considered the bearing property of impact of himself, can use the very high carbide alloy of microhardness, improves its anti-wear performance.
