Description
Technical Field
The utility model relates to a breaker equipment spare part field, concretely relates to breaker grate plate.
Background
The crusher is a conventional crushing machine and is mainly used for crushing raw materials for cement production, and raw ores can be crushed to the granularity required by grinding at one time through crushing of the crusher. Because the particle size of raw ore is larger, the particle size of stone materials crushed by stress in the crusher is also larger, and the crushed raw ore does not meet the production requirement of small particle size of sandstone aggregate, the peripheral wall and the bottom in the cavity of the crusher are subjected to great impact force in the crushing process of the raw ore, and particularly, a grate plate for filtering is arranged at the round bottom, so that the bearing capacity of the grate plate is required to be improved, and the particle size of the sandstone aggregate filtered from the grate plate meets the production requirement. Due to the limitations of the prior art, the grate plate adopted by the existing crusher still can not meet the use requirements far away.
SUMMERY OF THE UTILITY MODEL
The utility model discloses to the problem that above-mentioned exists, provide a breaker grate plate, load capacity is stronger, can filter out the product that accords with grit aggregate production requirement, arranges the material moreover more smoothly.
The utility model discloses a realize above-mentioned purpose, take following technical scheme to realize:
a crusher grate plate comprises an arc-shaped grate plate body, wherein the grate plate body comprises a plurality of grate bars which are uniformly distributed and have the same width, a grate seam is formed between every two adjacent grate bars, wave teeth are arranged on the surfaces of the grate bars, facing the circle center of the circle where the circular arc is located, the surfaces of the grate bars, far away from the circle center of the circle where the circular arc is located, are smooth cambered surfaces, the grate seam is trapezoidal in the thickness direction of the grate plate body, the width of a feeding hole of the grate seam, on the surface of the wave teeth of the grate bar, is 5 cm, and the width of the grate seam, on a discharging hole of the smooth cambered surface of the grate bar, is 4 cm.
Preferably, the arc of the grate plate body is 60 °.
Preferably, the plurality of grate bars are arranged in parallel along the direction of the circular arc.
Preferably, the grate plate is integrally molded and cast by adopting a metal material.
Preferably, the thickness of the grate plate body is 7 cm.
Compared with the prior art, the beneficial effects of the utility model are as follows:
the utility model discloses a grate bar and grate structure are favorable to making the smooth and easy discharge of grit aggregate after the breakage, also can produce the grit aggregate that meets the requirements, and the wave tooth surface of grate bar has effectively strengthened the wear resistance and the load capacity of grate bar.
Drawings
FIG. 1 is a schematic view of the front view structure of a crusher grate plate of the present invention;
FIG. 2 is a side cross-sectional view of a crusher grate plate of the present invention;
fig. 3 is a side view of the crusher grate plate of the present invention.
Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Referring to fig. 1-3, a crusher grate plate comprises an arc-shaped grate plate body 1, wherein the grate plate body 1 comprises a plurality of grate bars 2 which are uniformly distributed and have the same width, a grate seam 3 is formed between every two adjacent grate bars 2, wave teeth 21 are arranged on the surfaces of the grate bars 2 facing the circle center of a circle where an arc is located, the surfaces of the grate bars 2 far away from the circle center of the circle where the arc is located are smooth arc surfaces 22, the grate seam 3 is in a trapezoidal shape in the thickness direction of the grate plate body 1, the width of a feed inlet 31 of the grate seam 3 on the surfaces of the wave teeth of the grate bars 2 is 5 cm, and the width of a discharge outlet 32 of the grate seam on the smooth arc surfaces of the grate bars is 4 cm.
In the embodiment, the design of the grate bars can enhance the bearing capacity and the wear resistance of the grate plate, the design of the grate seams can lead the discharge to be smoother, and the grate plate can produce products meeting the production requirements of sandstone aggregates.
Optionally, the radian of the grate plate body 1 is 60 °. Through the structure, the grate plates are assembled and installed on the grate frame together with a plurality of blocks when in actual use, so that each grate plate is independent, and the grate plate with serious abrasion can be replaced when the grate is abraded and needs to be maintained, so that the service efficiency of the grate plate is higher, and the maintenance of the grate is more convenient and simpler.
Optionally, a plurality of grate bars 2 are arranged in parallel along the arc direction. Through the structure, the grate bars are arranged in parallel, so that the grate seams are also arranged in parallel, and the grate plate can discharge materials more smoothly after being arranged along the working direction of the crusher rotor.
Optionally, the grate plate is integrally molded and cast by using a metal material. The thickness of the grate plate body 1 is 7 cm. By the structure, the bearing capacity of the grate plate is greatly enhanced.
Compared with the prior art, the beneficial effects of the utility model are as follows:
the utility model discloses a grate bar and grate structure are favorable to making the smooth and easy discharge of grit aggregate after the breakage, also can produce the grit aggregate that meets the requirements, and the wave tooth surface of grate bar has effectively strengthened the wear resistance and the load capacity of grate bar.
However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention should not be limited thereby, and all the simple equivalent changes and modifications described in the claims and the specification of the present invention are included in the scope of the present invention. In addition, the abstract and the title are provided for assisting the search of patent documents and are not intended to limit the scope of the present invention.
