Abstract
The utility model relates to a hammer head and discloses a hard alloy hammer head applied in a crusher. The hard alloy comprises a hammer head body and a connecting bar, wherein a plurality of screw mounting holes are formed in the surface of the hammer head body; small hard alloy hammer heads are mounted in the screw mounting holes; the top of each small hard alloy hammer takes the shape of a hemisphere. According to the hard alloy hammer head, as small hard alloy hammers are fixed on the hammer head body surface through the screws, the disassembly is convenient, the replacing operation is simple and convenient; as the top end of the small hammer is hemisphere-shaped, the wear degree can be reduced and the service life of the hammer head is prolonged.
Description
Technical field
The utility model relates to a kind of tup, relates in particular to a kind of hard alloy hammer being applied in disintegrating machine.
Background technology
Disintegrating machine is widely used in numerous departments such as mine, smelting, building materials, highway, railway, water conservancy and chemical industry
, alloy tup is key components and parts in various crushing mechanisms, it mainly plays bulk object is knocked by alloy tup, attrition crushing, general, the hardness of tup is all greater than the hardness of the material that is broken, but difference degree is because the relation of material, can not differ too large, in addition because the highest hardness value being broken in thing has randomness, be difficult for determining, therefore in use, tup becomes one of part very easily wearing and tearing in disintegrating machine, and employing at present is all monoblock type tups, once it in use produces after wear damage at a certain position of tup, whole tup will be scrapped.The coupling part stability of tup and disintegrating machine contributes to improve the service life of tup, and long-time use of tup is certain to wear and tear, at this moment will change tup, carbide alloy on general tup is that welding manner is fixed on tup, when replacing, whole tup need to be replaced, so not only waste resource material, and replacing speed is slow.And increase the service life of tup and will directly have influence on output and the operating efficiency of disintegrating machine, so also need to improve the service life of tup in the situation that practicing every conceivable frugality resource.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, provide a kind of simple in structure, change convenience, long-lived hard alloy hammer,
For solving the problems of the technologies described above, the utility model provides a kind of hard alloy hammer, it comprises tup body and connecting rod, described tup body surface is provided with some threaded mounting holes, the little tup of carbide alloy is installed in described threaded mounting hole, be convenient to dismantle the little tup of carbide alloy, described carbide alloy hand hammer crown portion is hemispherical, can reduce the degree of wear.
Further, the little tup of described carbide alloy is uniformly distributed in described tup body surface or is randomly distributed in described tup body surface.
Further, described tup body one end has screw thread fixing hole.
Further, described connecting rod adopts and is threaded with described tup body, and described tup body can firmly be fixed on described connecting rod, is not easy to produce rock or come off.
The beneficial effects of the utility model are: this use is novel to be provided with by the little tup of the fixing carbide alloy of screw thread at tup body surface, for convenience detach, changes simple to operation; And thereby little top of hanging one's head is the hemispherical service life that can reduce degree of wear raising tup.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1, connecting rod; 2, screw thread fixing hole; 3, tup body; 4, the little tap of carbide alloy; 5, threaded mounting hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further set forth.
As shown in Figure 1, a kind of hard alloy hammer, it comprises tup body 3 and connecting rod 1, tup body 3 surfaces are provided with some threaded mounting holes 2, carbide alloy hand hammer head 4 is installed in threaded mounting hole 2, the mode being threaded that adopts carbide alloy hand hammer head 4 is fixed on tup body 3 is convenient to dismantle carbide alloy hand hammer head 4, saves labour and working time, avoids large-area dismounting operation.Carbide alloy hand hammer head 4 tops are hemispherical, can reduce its degree of wear, thereby make carbide alloy hand hammer head 4 more durable.
Carbide alloy hand hammer head 4 is uniformly distributed in tup body 3 surface or random tup body 3 surfaces that are distributed in, and in the time that carbide alloy hand hammer head 4 contacts with broken thing, can better accomplish that particle size after cracking is little, the low effect of wearing and tearing.
Connecting rod 1 adopts and is threaded with tup body 3, and tup body 3 can firmly be fixed on connecting rod 1, is not easy to produce rock or come off, and has broken precision better, the advantage that noise is little.
More than show and described general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; in the prerequisite that does not depart from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent.
Claims (4)
