Abstract

The utility model discloses a multi-prismatic cutting pick, comprising an alloy provided with multiple prismatic surfaces at the arc of the front end, wherein the multi-edge-shaped cutting pick is mainly used for engineering machinery, ore extraction and coal mining. The multi-edge-shaped cutting pick has the characteristics that the usual smoothly-transited shape of an alloy for the traditional cutting pick is broken through, and the plurality of inclined edges are machined at the arc of the front end of the multi-edge-shaped cutting pick and are uniformly distributed; during the use of the cutting pick, the own rotating performance can be greatly improved, and eccentric wear can be effectively prevented; the contact and the collision with a shovelled object are trended to a surface from a line, so that the overall impact resistance is enhanced; and moreover, a self-rotating eccentric component force is easier to derive, so that the stress of the cutting pick is shared, and the cutting pick is not easy to break, thus prolonging the service life of the cutting pick, reducing the labour intensity brought by frequently replacing the cutting pick by workers, and increasing the working efficiency.

Description

A kind of many prismatics pick

Technical field

The utility model belongs to the conical cutting pick for coal cutter field, also comprises taper engineering cutter.

Background technology

Conical pick is mainly used in the excavation in engineering machinery, ore extraction, colliery, and its structure is the head soldering traditional cylindrical alloy at the conical pick body.

During the work of tradition pick, often because of the rounding off profile of pick alloy front end, effectively rotation under the impact of the coal seam of complexity landform and detritus stream is bored thereby frequent appearance is sliding, causes the pick eccentric wear, pick body Fast Wearing, and alloy comes off, and collapses the phenomenons such as tooth; The rotation performance of Effective Raise pick is one of top-priority key factor when being engaged in the pick developmental research both at home and abroad.

Summary of the invention

The utility model purpose is to overcome the shortcoming of existing product, and a kind of perfect rotation performance that has is provided, and makes its more derivative rotation eccentric component, effectively prevents eccentric wear, improves the pick in the application life of pick.

The purpose of this utility model is achieved in that

A kind of many prismatics pick mainly is comprised of the alloy (2) that pick body (1), front end circular arc place process a plurality of slant edge faces; It is characterized in that: the place processes a plurality of equally distributed slant edge faces at pick front end alloy circular arc.

Main feature is the alloy that the soldering of pick body front end is special, front end circular arc place processes a plurality of slant edge faces, utilizes the existence increasing pick of slant edge face and the friction in coal seam, and then the rotation performance of Effective Raise pick, the hidden danger that reduces eccentric wear or collapse tooth.

After the utility model adopts said structure, according to the structure situation of different pick bodies and alloy, size, shape and the uniform quantity etc. of scientific and reasonable adjustment slant edge face, the rotation performance when using with further raising pick, the application life of prolongation pick.

The specific embodiment

Below in conjunction with accompanying drawing example of the present utility model is elaborated

As shown in drawings, the utility model is a kind of novel many prismatics pick, and the alloy (2) of mainly processing a plurality of slant edge faces by pick body (1), circular arc place forms.

The effectively welding of alloy (2) of adopting copper or silver brazing technique that pick body (1) is processed a plurality of slant edge faces with the circular arc place.

The utility model can adapt to engineering machinery, the ore extraction of various hardness rock stratum, the excavation in colliery fully, selects the space for the user provides better pick.

Claims

1. prismatic pick more than a kind mainly is comprised of the alloy (2) that pick body (1), front end circular arc place process a plurality of slant edge faces; It is characterized in that: the place processes a plurality of equally distributed slant edge faces at pick front end alloy circular arc.
