Abstract
A kind of plate hammer equipped with rich chromium cast iron abrasion-proof stick, including fan-shaped hammer body, the one end of fan-shaped hammer body far from its arc surface, which extends outwardly one section, to be formed and the matched convex body of rectangular recess, convex body is fastened in rectangular recess and passes through installation bolt and fan-shaped hammer body is mounted on boss, several circular grooves being radially distributed are dug on the sector of fan-shaped hammer body 1, spring is installed, one end of spring is fixed on circular groove bottom, rich chromium cast iron abrasion-proof stick is connected on the other end in circular groove.The application is provided with several rich chromium cast iron abrasion-proof sticks; it can to form many structures the same similar to sawtooth on the working face of plate hammer; the breaking capacity of plate hammer can relatively be increased in this way, while can also be played a protective role to the working face of plate hammer, so as to extend the service life of plate hammer.
Description
Technical field
The present invention relates to a kind of breaking device, more particularly, to a kind of plate hammer equipped with rich chromium cast iron abrasion-proof stick.
Background technology
The service life of general plate hammer for crusher is short, and the big of consumption, which needs to lay in a large amount of spare part, could maintain normal life
It is high to produce production costs.
There are two the reason of general plate hammer for crusher service life is short is general：
First, plate hammer for crusher material selection is improper.General plate hammer for crusher material type selecting is improper, leads to hardness and tough
Property is unable to reach technological requirement.And since the limitation shape of cost can not also use the material of higher cost.
Second is that board hammer structure selection is improper.The many working faces of plate hammer for crusher structure type have generous and narrow thin by two
Effective wear extent generous kind is big：There are single head work and double end work, the single heads for having single side work and double-face working only have
There are two wear surfaces for one wear surface double end.
Invention content
The purpose of the present invention is to solve the problem of the short wear surface rapid wear of plate hammer service life in the prior art, carry
For a kind of plate hammer equipped with rich chromium cast iron abrasion-proof stick.
The deficiency of the present invention to solve above-mentioned technical problem, used technical solution are：
A kind of plate hammer equipped with rich chromium cast iron abrasion-proof stick, including rotor, uniformly distributed three rectangular boss on the excircle of rotor,
Boss offers rectangular recess on one end far from rotor, further includes fan-shaped hammer body, the one end of fan-shaped hammer body far from its arc surface
Extend outwardly one section formed with the matched convex body of rectangular recess, convex body is fastened in rectangular recess and passes through installation bolt will be fan-shaped
Hammer body is mounted on boss, several circular grooves being radially distributed are dug on the sector of fan-shaped hammer body 1, round recessed
Spring is installed, one end of spring is fixed on circular groove bottom, rich chromium cast iron abrasion-proof stick, Gao Ge are connected on the other end in slot
Cast iron abrasion-proof stick initial tension of spring effect under shrink with circular groove in, when the rotating speed of rotor reaches setting value, Gao Gezhu
The pretightning force that the centrifugal force of iron abrasion-proof stick is more than spring will stretch out circular groove, and the maximum overhang of rich chromium cast iron abrasion-proof stick is height
The 1/3-1/2 of chrome cast iron abrasion-proof stick total length.
Offered on the boss vertically with rectangular recess and through the bolt hole of plateau sidewall, offer on convex body with
The matched through-hole of bolt hole.
The fan-shaped hammer body is made of high violent cast iron.
The beneficial effects of the invention are as follows：The application is provided with several rich chromium cast iron abrasion-proof sticks, in its course of work, stretches
Go out circular groove, can to form many structures the same similar to sawtooth on the working face of plate hammer, can increase brokenly in this way
The crushing effect of broken machine is easy to sawtooth to fracture at low speeds, therefore sets spring and be strapped in circular groove
It is interior, it only can just be stretched out after its high-speed rotation, can relatively increase the breaking capacity of plate hammer in this way, while to the work of plate hammer
Face can also play a protective role, so as to extend the service life of plate hammer.

Specific embodiment
Shown in Fig. 1, specific embodiment is as follows：
A kind of plate hammer equipped with rich chromium cast iron abrasion-proof stick, including rotor 3, uniformly distributed three rectangles are convex on the excircle of rotor 3
Platform 2, boss 2 are evenly distributed on the excircle of rotor 3, and boss 2 offers rectangular recess 201, square on one end far from rotor
Connected in star is what is dug from the one end of boss far from rotor to rotor direction, while rectangular recess in the rotor run through by heart line direction
Boss further includes fan-shaped hammer body 1, and the fan-shaped one end of hammer body 1 far from its arc surface, which extends outwardly one section, to be formed and rectangular recess 201
Matched convex body, convex body are located at fan-shaped circle centre position, and convex body is fastened in rectangular recess 201 and passes through installation bolt 4 and hammers sector into shape
Body 1 is mounted on boss 2 so that hammer body rotates together with rotor, hammer body to be driven to work, on the sector of fan-shaped hammer body 1
Several circular grooves 101 being radially distributed are dug, spring 5 are installed in circular groove 101, one end of spring 5 is consolidated
101 bottom of circular groove is scheduled on, rich chromium cast iron abrasion-proof stick 6 is connected on the other end, rich chromium cast iron abrasion-proof stick 6 is in initial tension of spring
In the lower contraction of effect and circular groove 101, when the rotating speed of rotor reaches setting value, the centrifugal force of rich chromium cast iron abrasion-proof stick is more than
The pretightning force of spring will stretch out circular groove 101, and the maximum overhang of rich chromium cast iron abrasion-proof stick 6 is total for rich chromium cast iron abrasion-proof stick 6
The 1/3-1/2 of length by the rotor speed of setting, calculates centrifugal force, to choose the spring for coefficient of elasticity.
It offers on the boss 2 and is vertically opened up with rectangular recess 201 and on the bolt hole of plateau sidewall, convex body
Have and the matched through-hole of bolt hole.
The fan-shaped hammer body 1 is made of high violent cast iron.
Technical solution and embodiment cited by the present invention and non-limiting, with the technical solution cited by the present invention and
Embodiment is equivalent or effect same approach is all in the range of the present invention protects.
