Description

A kind of rotor of hammer type crusher

Technical field

The utility model relates to a kind of rotor, and more particularly, it relates to a kind of rotor of hammer mill.

Background technology

Hammer mill mainly completes broken material operation by impact energy.During hammer mill work, High Rotation Speed made by driven by motor rotor, after material enters disintegrating machine chamber, under the pivotal tup of high speed impacts, shear, tear material, until material is broken, simultaneously, the Action of Gravity Field of material self makes material rush at support body Internal baffle, grating from the tup of High Rotation Speed, and the material detention being greater than screen size continues the strike and the grinding that are subject to hammer on sieve plate, until be crushed to required discharging-material size finally by outside sieve plate discharge machine.

In general, the structure of hammer mill includes casing, rotor, tup, liner plate and beater plate.And rotor is made up of main shaft, hammer dish and hammer first class sections.A hammer mill major part is rotor portion, and in the process of its work, the quality, impulsive force etc. of tup are born by rotor portion.

At present, the hammer mill on market, its rotor includes main shaft, hammer dish and tup.Tup is fixed on hammer dish, and hammer dish again radial direction is fixedly installed on main shaft.When hammer mill energising work, material pours the crusher chamber of hammer mill inside into from charging aperture, and driven by motor main shaft rotates, and main shaft drives hammer disc spins, then hammers dribbling into shape and moves tup rotation, reach broken effect with this.And common theory, material can not evenly be poured into when pouring hammer mill inside into.So just make material can not obtain sufficient fragmentation within the very first time in crusher chamber, material that could not be completely broken is made also to need to stay in disintegrating machine inside for a long time, reduce the efficiency of hammer mill work, and when workload is large time, easily cause the accumulation of material, and make stuck, fault of hammer mill inside etc., thus cause a series of accident affecting operating personnel's personal safety.

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of material that can make to obtain evenly broken rotor of hammer type crusher sooner.

For achieving the above object, the utility model provides following technical scheme: a kind of rotor of hammer type crusher, comprise main shaft, some tups and the some countershafts for installing tup, further comprises the cover plate that two pieces of spirality hammer dishes and two pieces are fixedly connected on main shaft two ends respectively, the rotation direction of described two hammer dishes is contrary.

By adopting technique scheme, spiral two hammer dishes all can be fixed on the cover board, so just make hammer mill operationally, hammer dish can along with main shaft together synchronous rotary, and the hand of spiral again because of two spirality hammer dishes is contrary, so when its work, material enters crusher chamber, under the effect of spirality hammer dish, can disperse fully, so just make material can not because of more concentrated when pouring into, and can not reach rapidly even fragmentation is carried out to all materials.By the hammer dish that these two hands of spiral are contrary, can drive material movement initiatively, by material axially dispersed, make the efficiency of its fragmentation higher, when the material of fragmentation identical amount, the working time reduces greatly, improves the effect to material fragmentation, reaches better fragmentation.

The utility model is set to further: described countershaft is all fixed on cover plate through two hammer dishes.

By adopting technique scheme, due to hammer mill operationally, due to motor High Rotation Speed and and material between collision, rotor can be made to bear very large impulsive force, and countershaft is passed two hammer dishes and is fixed on cover plate, like this countershaft can play the fixation to hammer dish, strengthens the shock resistance of hammer dish, make its intensity higher, not fragile.

The utility model is set to further: two hammer dishes all and leave gap between main shaft around the axial screw of main shaft.

By adopting technique scheme, between two hammer dishes and main shaft, leaving gap, saved hammer dish and manufactured material used, and the effect of better homogeneous material can be reached.Hammer dish is arranged to the axial screw around main shaft, and such material that just makes can produce the effect of evenly scattering smoothly in the axis of main shaft.

The utility model is set to further: described tup installation place is provided with axial limiting part.

By adopting technique scheme, the place of hanging one's head is axially arranged with locating part, so just limit moving axially of tup, it can not be made operationally to move around and break hammer dish, in turn ensure that tup can rotate in radial direction simultaneously, operationally, there is certain centrifugal force, reach better crushing effect.

The utility model is set to further: the material of described main shaft and the material of tup are steel alloy.

By adopting technique scheme, due to the metal material that steel alloy is comparatively hard, make the use that tup operationally can be more permanent, and main shaft adopts such material to arrange, also main shaft can be made more to stand temper, and highdensity main shaft ensure that its stability when rotated.

Detailed description of the invention

Referring to figs. 1 through Fig. 2, the utility model rotor of hammer type crusher embodiment is described further.

A kind of rotor of hammer type crusher as shown in Figure 1, comprise main shaft 6, some tups 2 and four countershafts 5 for installing tup 2, further comprises the cover plate 1 that spiral first hammer dish 3, second hammer dish 4 and two pieces are fixedly connected on main shaft 6 two ends respectively, four countershafts 5 here, main shaft 6, first hammer dish 3 and the second hammer dish 4 all weld with on cover plate 1.The hand of spiral of the first hammer dish 3 is clockwise, the hand of spiral of the second hammer dish 4 be counterclockwise, and two hammer dishes all and leave gap between main shaft 6 around the axial screw of main shaft 6.Like this be arranged so that material is when entering crusher chamber, full and uniform effect can be obtained.To originally concentrate the axis of material along main shaft 6 of side, and can evenly scatter axial to main shaft 6 fully by the effect of the first hammer dish 3 and the second hammer dish 4.Improve broken effect, accelerate broken speed.Here four countershafts 5 are all through two hammer dishes, and such setting is equivalent to the structure strengthening hammer dish, make it stressed larger, and fixed effect are better.

Countershaft 5 is provided with some tups 2, and tup 2 installation portion is provided with thrust bearing 7, and its effect is the movement of tup 2 at axial restraint, makes it can not move on countershaft 5, and can with countershaft 5 for rotating shaft rotation.Above-mentioned structure is all installed on the gap location between two hammer dishes.Such setting, make rotor when rotation, tup 2 can not touch two hammer dishes, makes two screw hammer dishes damaged and does not reach the result of use of expection.During work, tup 2 can rotate under the influence of centrifugal force, increases the crushing force of tup 2 pairs of materials, and being more prone to becomes small particles material by large granular materials fragmentation.

Because tup 2 is rotatable in the present embodiment, main shaft 6 often can contact material again with tup 2, in order to keep the life-span of rotor, have employed alloy steel material to make main shaft 6 and tup 2 in embodiment.Simultaneously heavier main shaft 6, when self rotates, can play the effect of the stability strengthening whole rotor arrangement.

The above is preferred embodiment of the present utility model, under not departing from the prerequisite of the utility model principle to those skilled in the art, can also make some modification and improvement, and these also should be considered as this and use novel protection domain.
