Abstract
The utility model discloses a hammerhead structure of a coal pulverizer breaking hammer. The hammerhead structure comprises a hammer handle (1) and a hammerhead (2), wherein a step is formed in one side of the hammerhead (2); a hard alloy block (3) is arranged inside the step through a screw (5). The hard alloy block can be replaced just by dismantling a bolt while the overall hammer does not need to be dismantled, so that the utilization rate of the hammer handle is improved by over 10 times.
Description
Technical field
The utility model relates to the fine coal hammer tup on a kind of coal pulverizer.
Background technology
Tup is the easily worn part on powder coal pulverizer, and to the fineness track lifting important function of fine coal, when after tup wearing and tearing 5-8mm, the fineness of coal grain does not just reach predetermined dimension, need to change tup.Existing tup is overall structure, and carbide alloy part is welded on tup, when tup occurs after wearing and tearing needing whole hammer to replace, relatively wastes resource.
Summary of the invention
The technical problems to be solved in the utility model: for the problem that needs all to change after existing monoblock type quartering hammer wearing and tearing, provide a kind of quartering hammer of combining structure.
Technical solutions of the utility model:
A kind of coal pulverizer breaking hammer head structure, comprises hammer handle and tup, and tup one side is offered step, in step, by screw rod, hard alloy blocks is installed.
There is screening glass in root hard alloy blocks outside.
Step side on tup has groove.
The utility model beneficial effect:
In use, the most exposed to contact ore position is hard alloy blocks to quartering hammer, and this part weares and teares at first, when may wear to can not continue to use time, only need to pull down screw is replaceable hard alloy blocks, does not need whole hammer dismounting, and the utilization rate of hammer handle has improved more than 10 times.Screening glass plays alloy-compressing piece and protects it not to be subject to hard thing impact grinding.Groove can prevent that alloy block from rotating.
Can also be only will after alloy block tune, continue to use, improve alloy service life more than 6 times.
brief description of the drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the cross-sectional view of removing after part.
Fig. 3 is the forward schematic diagram of Fig. 2.
detailed description of the invention:
Embodiment 1: the present embodiment is the transformation that existing coal pulverizer quartering hammer is carried out; quartering hammer is made up of hammer handle 1 and tup 2; first on tup, mill out one step; mill out groove one in the side of step again; in the boring of groove middle part; then hard alloy blocks 3 is processed into convex shape, itself and screening glass 4 are put on step, screening glass 4 is positioned at outside.Hard alloy blocks 3 middle part borings, screening glass 4 middle part drilling and tappings, all with concordant with the hole in step, finally link together tup 2, hard alloy blocks 3 and screening glass 4 through 3 holes with screw 5.After the working face of hard alloy blocks 3 is worn, can pull down screw 5 by hard alloy blocks 3 reverse end for end install, make its not wear surface adjust to working face.The alloy block 3 of groove after can wear prevention causes installing rear rotation because its wear surface is round and smooth.
