Abstract

The utility model belongs to a fitting of the rock processing machinery and relates to the flat hammer of a back impact crusher. The fitting has a strip-block matrix with an exterior eaves on the upper half of the matrix at the impacting side jutting out from the matrix. The blending surface of the top of the eaves and the matrix surface at the root of the eaves is an inclined or curved surface. The contour line at the upper edge of the matrix does not parallel the horizontal direction with the part near the exterior eaves higher and near the other side lower. The utility model has a reasonable structure, wear resistance, a long service life and a high crushing efficiency.

Description

The impact breaker bar

The utility model belongs to the accessory of rock processing equipment, relates to a kind of impact breaker bar.

Impact breaker is mainly used in industries such as mine, building, chemical industry, electric power, metallurgy, materials such as breaking ores, rock, slag, coal.It is by being installed in bar on the armature spindle with armature spindle high speed rotating percussion machined material etc., and it is broken in throwing repeatedly, bounce-back process.Existing impact breaker bar profile is generally cuboid, in use its force-bearing situation is unreasonable, not only crushing efficiency is lower, and bar very easily weares and teares, service life is shorter, increased the equipment use cost, the bar to heaviness carries out frequent replacing simultaneously, has also increased operator's labour intensity.

Technical problem to be solved in the utility model is, overcomes the defective of existing bar, provides a kind of rational in infrastructure, and is not easy to wear, long service life, and the high impact breaker bar of crushing efficiency.

Impact breaker bar of the present utility model comprises the matrix of a strip and block, upper semisection at its matrix, be positioned at a side of striking face, the outer eaves that an outstanding matrix is arranged, transition face between the matrix surface of outer eaves top and root is inclined-plane or curved surface, and in addition, the outline line and the horizontal direction of matrix upper end-face edge are not parallel, be that outline line is higher near outer eaves one side, lower near opposite side.In order further to improve the utilization rate of every bar, the lower semisection of bar matrix can be identical with the upper semisection shape, and be centrosymmetric, and after the upper semisection wearing and tearing, bar can be turned around to install, and utilizes lower semisection to continue to use.

The utility model is because in the use, the material that is clashed into is under the guide effect of transition face, and head-on crash takes place at main and striking face middle part, and reduced the friction of material and matrix border, thereby greatly reduce wearing and tearing, improved service life, and crushing efficiency height.

Fig. 1 is a striking face Facad structure schematic diagram of the present utility model;

Fig. 2 is the lateral plan of Fig. 1;

Fig. 3 is that the A of Fig. 1 is to cutaway view;

Fig. 4 is the structural representation of another embodiment of the utility model.

As Figure 1-3, the upper semisection of impact breaker bar matrix 1 of the present utility model is positioned at a side of striking face, and the outer eaves 2 of an outstanding matrix is arranged, and the transition face 4 between the matrix surface of outer eaves top 3 and root is inclined-plane or curved surface.The outline line 5 of matrix upper end-face edge is not parallel with horizontal direction, and promptly outline line is higher near outer eaves one side, and is lower near opposite side.

That shown in Figure 4 is another embodiment of the present utility model, and the lower semisection of its matrix 1 is identical with the upper semisection shape, and is centrosymmetric.After the upper semisection wearing and tearing, bar can be turned around to install, utilize lower semisection to continue to use the service life of further having improved every bar.
