Abstract
The utility model discloses a wear-resistant grate for a hammer crusher and belongs to the technical field of mining machinery. The wear-resistant grate comprises a grate body, wherein a plurality of discharging through holes are formed in the grate body; each discharging through hole is provided with a wear ring; each wear ring is provided with a tapered discharging passage; the inner diameter of a feeding opening in each wear ring is smaller than that of a discharging opening in the wear ring; the wear rings and the grate body are integrated by casting. Therefore, when the wear-resistant grate is in use, materials are smoothly discharged through the tapered discharging passages; the materials are prevented form being jammed so as not to affect production. Meanwhile, due to the wear rings, wear caused by material collision is reduced; the service life of the wear-resistant grate is prolonged; the replacement frequency of the grate body is reduced; the use cost of the wear-resistant grate is lowered; the production efficiency is guaranteed.
Description
Technical field
The utility model belongs to the mining machinery technical field, relates in particular to a kind of hammer mill with wear-resisting grate bar.
Background technology
Grate bar used on the present stage hammer mill, be cast into one and the grate bar is provided with some through holes with the violent abrasion-resistant stee of height, although high violent abrasion-resistant stee has good wear-resisting effect, but along with the lasting collision of material to the grate bar, through hole wearing and tearing on this grate bar become large, affect the discharge of material, thereby affect production efficiency; And so forth, need periodic replacement grate bar, cause use cost to increase.
The utility model content
The purpose of this utility model is to provide a kind of hammer mill wear-resistant grate bar, guarantees under the prerequisite of production efficiency, realizes reducing and changes number of times, reduces use cost, improves the purpose in service life.
For solving the problems of the technologies described above, the technical solution of the utility model is: hammer mill is with wear-resisting grate bar, comprise grate bar body, described grate bar body is provided with some through holes for discharging, be equipped with wear ring on each described through hole, described wear ring has the tapping channel of taper, and the internal diameter of described wear ring upper feeding mouth is less than the internal diameter of described wear ring top discharge mouth, and described wear ring and described grate bar body are cast into one.
As a kind of improvement, the cross sectional shape of described through hole is taper, and the outer surface of described wear ring and the shape of described through hole are suitable, and described wear ring is positioned at the outer surface diameter of the outer surface diameter of described charging aperture one side greater than discharging opening one side of described wear ring.
Owing to having adopted technique scheme, the beneficial effects of the utility model are: because the through hole of grate bar body is provided with wear ring, this wear ring has the tapping channel of taper, the internal diameter of this wear ring upper feeding mouth is less than the internal diameter of wear ring top discharge mouth, and wear ring and grate bar body are cast into one.Thereby in the course of the work,, by the tapping channel of taper, guaranteed that material discharges smoothly, avoided material to block and affected production; Simultaneously,, due to the existence of wear ring, reduce the wearing and tearing that bring after the material collision, improved service life, reduced the replacing number of times of grate bar body, reduced use cost, guaranteed production efficiency.
Be positioned at the outer surface diameter of the outer surface diameter of charging aperture one side greater than discharging opening one side of wear ring due to wear ring.Thereby avoided wear ring to come off and do not had wear-resisting effect along the through hole discharge.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the enlarged drawing of wear ring in Fig. 1;
Fig. 3 is the cutaway view of Fig. 2;
In figure, 1-grate bar body; The 2-wear ring; The 3-through hole; The 4-charging aperture; The 5-discharging opening.
The specific embodiment
, in order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As Fig. 1 and Fig. 2 and Fig. 3 common as shown in, this hammer mill comprises grate bar body 1 with wear-resisting grate bar, this grate bar body 1 is provided with some through holes for discharging 3, the cross sectional shape of this through hole 3 is taper, be equipped with the wear ring 2 that is cast into one with grate bar body 1 on each through hole 3, this wear ring 2 has the tapping channel of taper, and the internal diameter of these wear ring 2 upper feeding mouths 4 is less than the internal diameter of wear ring 2 top discharge mouths 5; The shape of the outer surface of this wear ring 2 and through hole 3 is suitable, and this wear ring 2 is positioned at the outer surface diameter of the outer surface diameter of charging aperture 4 one sides greater than discharging opening 5 one sides of wear ring 2.
In actual applications, material to be got rid of is got rid of material by through hole 3, in the process of this discharge, the continuous grate bar of material body 1 clashes into, reduce the wearing and tearing that bring after the material collision due to the existence of wear ring 2, improved service life, reduced the replacing number of times of grate bar body 1, reduce use cost, guaranteed simultaneously production efficiency; In order to guarantee the smooth discharge of material, avoid material to be stuck in through hole 3 and impact is produced, the internal diameter of these through hole 3 upper feeding mouths 4 is less than the internal diameter of through hole 3 top discharge mouths 5.
The hammer mill that the utility model provides comprises grate bar body 1 with wear-resisting grate bar, this grate bar body 1 is provided with some through holes for discharging 3, be equipped with wear ring 2 on each through hole 3, this wear ring 2 has the tapping channel of taper, the internal diameter of these wear ring 2 upper feeding mouths 4 is less than the internal diameter of wear ring 2 top discharge mouths 5, and this wear ring 2 is cast into one with grate bar body 1.Thereby in the course of the work,, by the tapping channel of taper, guaranteed that material discharges smoothly, avoided material to block and affected production; Simultaneously,, due to the existence of wear ring 2, reduce the wearing and tearing that bring after the material collision, improved service life, reduced the replacing number of times of grate bar body 1, reduced use cost, guaranteed simultaneously production efficiency.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
