Abstract
The utility model discloses a board hammer of crusher, the bar includes hammer block, tup, the hammer block middle part is provided with the draw -in groove that is used for connecting the rotor, the tup set up in the both ends of hammer block, the tup is square cylinder, adopts the hammer block and the tup of components of a whole that can function independently, and the tup sets up to square cylinder, has improved the utilization ratio and the degree of fragmentation of bar, its simple structure, wear resistance is high, long service life, the tup is only changed to the hammer block that does not need to be changed after the wearing and tearing, and it is convenient to change, save material.
Description
Technical field
The utility model relates to impact breaker accessory field, is specifically related to a kind of bar of disintegrating machine.
Background technology
Impact breaker is a kind of Crushing equipment of novel efficient, and its principle drives bar High Rotation Speed by rotor, collide thus by material fragmentation with material high-speed, this crumbling method ratio of reduction is large, can be crushed to less granularity by disposable for material, its volume is little, simple structure, the ratio of reduction is large, less energy consumption, production capacity is large, and product granularity is even, and selectively muck effect, use extensively in the industry such as mine, cement.
At present, bar material many employings potassium steel, but in, in low impact wear situation, its impact phase transition hardening capacity can not give full play to, and show as wearability lower, service life is shorter, especially the ore of crushing hard, weares and teares even more serious, because high velocity impact is broken, quickly, in order to ensure discharging-material size, bar may wear to a certain degree just must be changed in the wearing and tearing of bar, therefore the replacing of bar is frequent, use amount is very large, not only causes production cost to increase, and impact is produced.
Utility model content
In view of this, the application provides a kind of bar of disintegrating machine, and its structure is simple, and anti-wear performance is high, long service life, and production cost is low, and crushing efficiency is high, is convenient to change.
For solving above technical problem, the technical scheme that the utility model provides is a kind of bar of disintegrating machine, and described bar comprises hammer body, tup, is provided with the draw-in groove for connecting rotor in the middle part of described hammer body, described tup is arranged at the two ends of described hammer body, and described tup is square cylinder.
Preferably, described tup is cubic cylinder, hexagonal prism body or all directions cylinder.
Preferably, the two ends up and down of described hammer body are respectively arranged with groove, and the corresponding connecting portion of described tup is provided with projection, and described hammer body and described tup are located by clamping.
Preferably, there is the bolt hole of hollow described tup inside, and described tup and described hammer body are bolted.
Preferably, have certain interval between described tup and described hammer body, described gap is not less than 10mm.
More preferred, the gap between described tup and described hammer body is not less than 15mm.
Preferably, described hammer body surface is also provided with one deck wearing layer.
More preferred, the thickness of described wearing layer is 10-20mm.
Preferably, described tup is high chrome alloy steel tup.
Preferably, described tup top is provided with concave surface.
The application compared with prior art, its beneficial effect is: the hammer body and the tup that adopt split, past one bar is improved to hammer body and tup two parts, tup is set to square cylinder, when bar works, each seamed edge on tup all collides with material, improves utilization rate and the degree of fragmentation of bar; In addition hammer body surface is welded with high-abrasive material, and the material of tup is high chrome alloy steel, and its anti-wear performance is high, long service life; Do not need after wearing and tearing to change hammer body, only change tup, it is convenient to change, and saves material.
Accompanying drawing explanation
Fig. 1 is the structure chart of bar described in the application.
Detailed description of the invention
In order to make those skilled in the art understand the technical solution of the utility model better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The bar of a kind of disintegrating machine as shown in Figure 1, described bar comprises hammer body 1, tup 2, the draw-in groove 3 for connecting rotor is provided with in the middle part of described hammer body 1, described tup 2 is arranged at the two ends of described hammer body 1, described tup 2 is cubic cylinder, the two ends up and down of described hammer body 1 are respectively arranged with groove 3, the corresponding connecting portion of described tup 2 is provided with protruding 4, described hammer body 1 is located by clamping with described tup 2, there is the bolt hole 6 of hollow described tup 2 inside, described tup 2 is bolted with described hammer body 1, between described tup 2 and described hammer body 1, there is certain interval, described gap is 20mm, described hammer body 1 surface is also provided with one deck wearing layer, the thickness of described wearing layer is 15mm, described tup 2 top is provided with concave surface 7.Wherein, described tup 2 is high chrome alloy steel tup.
In the present embodiment, adopt hammer body 1 and the tup 2 of split, past one bar is improved to hammer body 1 and tup 2 two parts, tup 2 is set to square cylinder, when bar works, each seamed edge on tup 2 all collides with material, improves utilization rate and the degree of fragmentation of bar; In addition hammer body 1 surface is welded with high-abrasive material, and the material of tup 2 is high chrome alloy steel, and its anti-wear performance is high, long service life; Do not need after wearing and tearing to change hammer body 1, only change tup 2, it is convenient to change, and saves material; Tup 2 top is provided with concave surface 7, more can keep changing with the contact angle of material very little like this within the wear-out period, ensures marker size expansion.
Below be only preferred embodiment of the present utility model, it should be pointed out that above-mentioned preferred embodiment should not be considered as restriction of the present utility model, protection domain of the present utility model should be as the criterion with claim limited range.For those skilled in the art, not departing from spirit and scope of the present utility model, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
