Abstract
The utility model discloses a part of breaker, specifically speaking are plated hammer of reversed crusher. It includes the base member of list structure, and first section of base member is provided with the outer eaves that is located impact face one side and outstanding base member, outline line nonparallel between the upper end rear portion of base member and the tip of outer eaves, and the outer eaves both sides of base member are provided with the dado that swells in the base member both sides, and the tip of the outer eaves of dado follow extends to between first section middle part of base member. After adopting foretell structure, reduced the material make the crushed aggregates can not enter into in the gap between bar and the casing lateral wall with base member fricative while of edge, the dado that is located the outer eaves both sides of base member to playing the effect that keeps off the material from this to prevent the wearing and tearing at bar side edge, guaranteed crushing effect, prolonged the life of bar.
Description
Technical field
This utility model relates to the parts of a kind of disintegrating machine, specifically a kind of board hammer of impact crusher.
Background technology
Existing impact breaker includes crusher chamber, the bar driven by rotor it is provided with in crusher chamber, strike material is transferred by the high-speed rotary of rotor, and for the structure of bar, the most typically use the matrix of list structure, one of them end face of matrix is as the scope of attack, during strike, bar is easily made to wear and tear, the cambered surface of unfilled corner is formed after the scope of attack weares and teares, so that force-bearing situation changes, directly affects the service life of bar, additionally, owing to having gap between bar and backplate, in making material easily enter into gap in shattering process thus be extruded, this extruding just makes bar edge Fast Wearing, crushing effect will be affected after serious wear, bar is finally made thoroughly to scrap, further shorten the service life of bar.
Summary of the invention
It is reasonable that the technical problems to be solved in the utility model is to provide a kind of smart structural design, the most easy to wear, thus extends the board hammer of impact crusher in its service life.
In order to solve above-mentioned technical problem, board hammer of impact crusher of the present utility model, matrix including list structure, the upper semisection of matrix is provided with and is positioned at striking face side the outer eaves of prominent matrix, contour line between upper rear and the end of outer eaves of matrix is not parallel, the outer eaves both sides of matrix are provided with the retaining wall being projected on matrix both sides, and retaining wall is between the end of outer eaves extends in the middle part of matrix upper semisection.
The lower semisection of described matrix is identical with upper semisection shape, and is centrosymmetric.
After using above-mentioned structure, it is positioned at striking face side the outer eaves of prominent matrix owing to the upper semisection of matrix is provided with, while decreasing material and matrix border friction, it is positioned at the retaining wall of the eaves both sides effect to playing backgauge outside matrix, so that particle will not enter in the gap between bar and housing sidewall, thus prevent the abrasion of bar lateral edge, it is ensured that and crushing effect, extend the service life of bar.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model board hammer of impact crusher；
Fig. 2 is the Section A-A structural representation of Fig. 1.
Detailed description of the invention
Below in conjunction with the accompanying drawings and detailed description of the invention, board hammer of impact crusher of the present utility model is described in further detail.
As shown in the figure, board hammer of impact crusher of the present utility model, matrix 1 including list structure, matrix 1 has striking face 4 and two sides, non-impact face 5, the back side, the upper semisection of matrix 1 is provided with and is positioned at striking face side the outer eaves 2 of prominent matrix, contour line 6 between upper rear and the end of outer eaves 2 of matrix 1 is not parallel (for broken line), i.e. contour line is higher near outer eaves side, relatively low near opposite side, the outer eaves both sides of matrix 1 are provided with the retaining wall 3 being projected on matrix both sides, and retaining wall 3 is between the end of outer eaves extends in the middle part of matrix upper semisection.
Further; the lower semisection of described matrix 1 is identical with upper semisection shape; and be centrosymmetric, thus form four sides protection structure, wherein; both sides are outer eaves 2 up and down; the left and right sides is retaining wall 3, due to when bar limit mouth wear and tear after, be not the most vertically to hit broken form during material pounding; and forming lonely face friction broken form, broken school rate can be along speed decay simultaneously because the change of broken form can cause bar unstable wear；The outer eaves 2 arranged is possible to prevent to be broken the moment that material contact with bar, because of kinetic energy transmission be broken material under the influence of centrifugal force, make material and bar contact point form relative displacement, it is to avoid to be formed because of the relative displacement of contact point and rub and the bar that weares and teares；The retaining wall 3 arranged prevents the gap that the material that is broken is perforated through between bar both sides and counterattack broken casing limit backplate, form the abrasion of bar and limit backplate, and after upper semisection weares and teares, can turn around bar to install, lower semisection is utilized to be continuing with, improve the utilization rate of bar, extend the service life of bar further.
Claims (2)
1. a board hammer of impact crusher, matrix (1) including list structure, the upper semisection of described matrix (1) is provided with and is positioned at striking face side the outer eaves (2) of prominent matrix, contour line between upper rear and the end of outer eaves (2) of matrix (1) is not parallel, it is characterized in that: the outer eaves both sides of described matrix (1) are provided with the retaining wall (3) being projected on matrix both sides, and described retaining wall (3) is between the end of outer eaves extends in the middle part of matrix upper semisection.
