Description

A kind of powdered metal parts pulverizer

Technical field

The utility model is related to reducing mechanism technical field, more particularly to a kind of powdered metal parts pulverizer.

Background technology

Pulverizer is the plant equipment to specifying material to carry out pulverization process.Common disintegrating apparatus structure such as notification number is A kind of Multifunctional auto-feed-crushing disintegrator of Chinese utility model of CN2579521Y, it includes outside main branch frame, outside Main branch inframe is provided with lightning wind type breaking plant and pulverizer, and lightning wind type breaking plant and pulverizer are in be distributed up and down；In reality When border uses, lightning wind type breaking plant and pulverizer start simultaneously, and two inner drive shafts of machine are connected directly between simultaneously Outside main branch frame, is usually susceptible to resonance in the course of work.

Still above-mentioned enlightenment, in the market is similarly occurred in that directly to be replaced the pulverizer below lightning wind type breaking plant It is a kind of vibrations screening machine of the Chinese utility model of CN203356055U to change notification number such as into, and its charging aperture is directly broken with lightning wind type The feed opening of crushing device is joined directly together, and lightning wind type breaking plant is carried out after broken work, is directly dropped in vibrations screening machine, Vibrations screening function is realized, although said structure can be realized broken and screen dual work, still there is resonance stronger Problem, can have a strong impact on overall structural strength, therefore it is the task of top priority to reduce covibration.

Utility model content

In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of powdered metal parts to crush Machine, its structure can reduce the generation of resonant conditions.

Above-mentioned technical purpose of the present utility model technical scheme is that：A kind of powdered metal parts Pulverizer, including vibrations screening machine, pulverizer, also including carriage, the carriage is provided with upper ledge face and lower frame face, described Vibrations screening machine be connected to the lower frame face, the pulverizer is connected to upper ledge face, the feed opening in the pulverizer with vibrations It is connected by hose connector between charging aperture in screening machine.

By above-mentioned technical proposal, in actual use, vibrations screening machine occurs to shake simultaneously with pulverizer；From shake The angle of power transmission is analyzed, and the shaking force for shaking screening machine is transferred directly on upper ledge face, afterwards by carriage point Supplementary biography is handed to the bottom surface of ground and pulverizer, and wherein most is transferred to ground；The shaking force of pulverizer can be transmitted directly To lower frame face；Accordingly, it is capable to the resonance power produced because being joined directly together between vibrations screening machine and pulverizer is greatly reduced, carry Rise overall structural strength.

Preferably, also including the hold-down mechanism on lower frame face, the bottom surface of the vibrations screening machine is provided with to extension The flange stretched, the hold-down mechanism forces in flange and vibrations screening machine is offseted with lower frame face.

By above-mentioned technical proposal, the setting of hold-down mechanism, when vibrations screening is motor-driven to be made, at utmost reduces reciprocating sieve Gap existing between machine bottom surface and lower frame face is selected, the mesh for reducing and being shaken between vibrations screening machine and lower frame face is finally reached 's.

Preferably, the hold-down mechanism includes some compressing members, and some compressing members are symmetrical to shake the center of screening machine Center circumferentially array distribution, is equipped with clamping screw on each compressing member, the compressing member two ends are abutting end, described Clamping screw is threadedly connected to lower frame face and makes two to push against end and pushes against respectively in flange, lower frame face.

By above-mentioned technical proposal, when needing to make flange be mutually brought into close contact with lower frame face, clamping screw only need to be tightened, And the coupling mechanism force of clamping screw is put on compressing member, two abutting ends of compressing member just can respectively be pressed in the upper surface of flange And lower frame face, will be brought into close contact between flange and lower frame face together with；When needing dismounting, also only need to reversely rotate locking screw Bolt, and clamping screw is disassembled from compressing member, compressing member just can directly obtain dismounting；Said process is ensureing to press-fit surely While qualitative, dismounting is convenient to.
