Abstract

The utility model discloses a kind of sand machine thrower head processed, bottom one, establish reeded matrix and the alloy bar be bonded in groove to form, described groove is V-arrangement, and described alloy bar is rhombus, the shape of described groove and the form fit of described alloy bar.The thrower head of the utility model diamond also can carry out exchanging using in turn while self wearability of raising, the utilization rate of the material both improved, again the available protecting life-span of sand machine inner circumferential backplate processed.Sand machine whole service life processed improves more than five times than original product. and sand efficiency processed improves more than 30%.

Description

A kind of sand machine thrower head processed

Technical field

The utility model relates to a kind of accessory of sand machine processed, is specifically related to a kind of thrower head.

Background technology

Thrower head belongs to the core position of vertical impact crusher (sand machine processed), and it is widely used in the industries such as mine, sandstone, cement, metallurgy, hydroelectric project.Thrower head is fixedly mounted on the rotor of sand machine processed, and when sand machine processed runs, rotor drives thrower head to rotate together, with the material generation high velocity impact be thrown into, thus by oarse-grained, that hardness is high crushing material.Thrower head is made up of matrix and carbide alloy bar, and alloy bar is embedded in the bottom of matrix, and blend compounds water bonding is formed.

The thrower head alloy bar of current use is generally square list structure, and the corresponding groove of substrate coordinated with alloy bar is square, and during sand machine comminuting matter processed, material impact thrower head, shock surface is the working face that first material contacts thrower head.Material impact thrower head, thrower head is worn and torn, the centre serious wear of alloy bar, while material wearing and tearing alloy bar working face, also cutting down width and the thickness of alloy bar, the width of alloy bar center and thickness reduce, when being reduced to a certain degree, alloy bar easily ruptures, and affects the normal operation of sand machine processed.Therefore, in order to make sand machine processed normally work, needing frequent replacing thrower head alloy bar, thus adding the operating cost of sand machine processed.

Utility model content

It is simple, wear-resistant that technical problem to be solved in the utility model is to provide a kind of structure, cost-effective one sand machine processed thrower head.

Technical problem to be solved in the utility model realizes by the following technical solutions:

A kind of sand machine thrower head processed, bottom one, establish reeded matrix and the alloy bar be bonded in groove to form, described groove is V-arrangement, and described alloy bar is rhombus; The shape of described groove and the form fit of described alloy bar.

The beneficial effects of the utility model are:

1) the sand machine thrower head processed that provides of the utility model, alloy bar is rhombus, can increase the thickness of alloy bar.Thrower head is by after material impact, and the core wearing and tearing of alloy bar, can form a plane, thus increase the width of alloy bar, makes can wearing-in period increasing of alloy bar, extends the service life of thrower head;

2) the sand machine thrower head processed that provides of the utility model, can wearing-in period because of what add alloy bar, extends the service life of thrower head, when sand machine processed runs, decreases the replacement frequency of thrower head, thus reduce the operating cost of sand machine processed;

3) the sand machine thrower head processed that provides of the utility model; because alloy bar is rhombus, reduce the production cost of alloy bar, and the weight alleviating alloy bar also can carry out exchanging using in turn simultaneously; the utilization rate of the material both improved, again available protecting life-span of sand machine inner circumferential backplate processed.

Detailed description of the invention

The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.

As Figure 1-4, a kind of sand machine thrower head processed, be made up of with the alloy bar 3 be bonded in groove 2 matrix 1 being provided with groove 2 bottom, described groove 2 is V-arrangement, and described alloy bar 3 is rhombus; The shape of described groove 2 and the form fit of described alloy bar 3.

Groove 2 adopts glue to bond with the bonding mode of alloy bar 3, and alloy bar 3 and groove of substrate 2 are closely cooperated.This alloy bar is rhombus, the thrower head of diamond also can carry out exchanging using in turn while self wearability of raising, the utilization rate of the material both improved, again the available protecting life-span of sand machine inner circumferential backplate processed.Sand machine whole service life processed improves more than five times than original product. and sand efficiency processed improves more than 30%.

More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.

Claims

1. a sand machine thrower head processed, bottom one, establish reeded matrix and the alloy bar be bonded in groove to form, it is characterized in that: described groove is V-arrangement, described alloy bar is rhombus, the shape of described groove and the form fit of described alloy bar.
