Description
Technical Field
The utility model belongs to the technical field of well hard brittle material crushing equipment, specifically be a grate plate for reversible counterattack hammer crusher.
Background
Reversible counterattack hammer crusher is a broken rotor can corotation, the novel crushing equipment of reversal, and reversible two counterattack hammer crusher mainly relies on the impact to break the material, has hammer crusher and the characteristics of counterattack formula breaker concurrently, and the breakage ratio is big, extensively is used for the system sand trade, can directly break to required granularity with river cobble, phyllite, sandstone. The reversible impact hammer crusher is used for fine crushing, and the key is how to obtain qualified fine materials under the condition of not increasing a closed-loop system. At present, two main grate structures exist at home and abroad: one of the casting structures adopts an integral casting structure, and a plurality of small holes are reserved during casting, so that the structure is difficult to cast, high in cost and long in period; and secondly, a plurality of cast through-length grate bars are embedded between the grate frames, the grate bars are easy to break off a large crusher, the requirements on materials are very strict, and the requirement on obtaining finer granularity cannot be guaranteed.
Disclosure of Invention
The purpose of the invention is as follows: the utility model aims to provide a not enough to exist among the prior art, the utility model provides a reversible backstroke hammer is grate plate for breaker to solve present reversible backstroke hammer and grate plate casting for breaker complicated, arrange the material unsmooth, degree of wear is big, the problem of easy rupture.
The technical scheme is as follows: in order to solve the technical problem, the utility model discloses a technical scheme be:
the utility model provides a reversible counterattack is grate plate for hammer crusher, plate body, curb plate, strengthening rib and grid section, the horizontal both sides of plate body are provided with the sideboard, and the vertical both sides of plate body are provided with the curb plate, all be provided with the boss on 2 curb plates, the plate body is provided with the bolt hole all around, and is provided with punishment in advance hole and grid section on the plate body terminal surface, be provided with locating piece and strengthening rib in the middle of the plate body.
Furthermore, the tangent plane of the plate body is arc-shaped.
Further, the plate body is made of wear-resistant steel NM 360.
Furthermore, the plate body is welded with the side plate and the side plate.
Further, the side plates and the side plates have different thicknesses.
Furthermore, the grid section is a transverse strip-shaped grid section.
Has the advantages that: compared with the prior art, the method has the following advantages:
the side plates and the side plates with different thicknesses are welded on the periphery of the grate plate for the reversible impact hammer crusher, and the side plates are provided with bosses and are used for being fixed on a grate frame at the bottom to prevent bolts from being sheared and broken. The grate plate for the reversible impact hammer crusher has the advantages that the middle part is provided with the reinforcing rib to prevent the deformation of the grate plate body, the manufacturing period of the grate plate is greatly shortened, the use is convenient and reliable, the product granularity meets the requirement, the service life can be prolonged by adjusting the height of the lower grate frame after abrasion, the structure is simple, and the manufacturing cost is low.
Drawings
FIG. 1 is a schematic view of a grate plate structure for a reversible impact hammer crusher;
fig. 2 is a side view of a grate plate for a reversible counterattack hammer crusher.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1-2, the grate plate for the reversible impact hammer crusher comprises a plate body 1, side plates 2, side plates 3, positioning blocks 4, reinforcing ribs 5 and grate bars 6, wherein the side plates 3 are arranged on two transverse sides of the plate body 1, the integral strength of the plate body 1 can be effectively enhanced, the side plates 2 are arranged on two vertical sides of the plate body 1, bosses are arranged on the 2 side plates 2, the bosses facilitate the plate body 1 to be fixed on a grate frame at the bottom, the bolts are prevented from being sheared and broken, bolt holes are formed in the periphery of the plate body 1 and used for fixing the grate bars, material passing holes and the grate bars 6 are formed in the end face of the plate body 1, the positioning blocks 4 and the reinforcing ribs 5 are arranged in the middle of the plate body 1.
The tangent plane of plate body 1 is the arc, is fit for the grinding to the coarse fodder more, and horizontal long waist hole is as the material passing hole to guarantee that the coarse fodder can not appear in the product.
The plate body 1 is made of NM360, the NM360 has obvious wear resistance and toughness, and good welding performance, and the NM360 plate body 1 can be better suitable for the grate plate for the reversible impact hammer crusher.
The plate body 1, the side plates 2 and the side plates 3 are welded, the overall strength of the grate plate is enhanced, the plate body 1 is more stably connected with the side plates 2 and the side plates 3, and the plate body 1, the side plates 2 and the side plates 3 cannot fall off each other due to long-time use.
The thickness of curb plate 2 and sideboard 3 is different, comes reasonable arrangement to different working strength, is extravagant material, saves the cost.
The grate 6 is a transverse strip-shaped grate, large materials flow downwards along the longitudinal direction and cannot pass through the transverse grate 6, the chance that the materials are beaten and crushed by the hammer head is increased, and then the materials are discharged from a discharge hole at the rear edge, so that the particle size of the product is ensured.
When a user needs to use the grate plate for the reversible impact hammer crusher to work, whether the grate plate for the reversible impact hammer crusher is obviously damaged or not is firstly checked, and the operation can be carried out after the safety check is carried out.
The utility model provides a thought and implementation method of reversible counterattack grate plate for hammer crusher, the concrete application way is many, only above the utility model discloses an optimal implementation mode should point out, to the ordinary skilled person in this technical field, is not deviating from the utility model discloses under the prerequisite of principle, can also make a plurality of improvements, these improvements also should be regarded as the utility model discloses a protection scope.
