Description
Technical field
The utility model belongs to field of cracking machine, more particularly to a kind of hammer mill.
Background technology
Hammer mill is suitable for being crushed medium-hard material in industrial departments such as cement, chemical industry, electric power, metallurgy, such as
Broken and fine crushing operation in the materials such as lime stone, clinker, coke, coal.Traditional hammer mill includes mainly motor, main shaft
Turntable, crushing mechanism, broken cavity and hopper, the crushing mechanism for break mined material are located in broken cavity and are fixed on master
On shaft rotation disk, under the drive of motor, crushing mechanism high speed rotation in crusher chamber body.Material inlet of the material from top hopper
Into in crusher chamber, hit, impacted by crushing mechanism, being sheared, abrasive action and crush.The tup of conventional breakers is installed
On rotor, the high-speed rotation of rotor drives tup to rotate and swing, high after material is entered from material inlet in crusher chamber body
The tup of speed rotation strikes material and rushes at and be fixed in crusher case from high-speed rotating tup after material obtains kinetic energy
On crushing shell, the material detention for being then more than grid section pore size continues strike and grinding by tup in crusher chamber body, directly
To required granularity is crushed to, finally by grid section discharge machine outside.But it is excessive, hard that humidity can be inevitably encountered in shattering process
The case where degree differs, may thus cause following problem：1, currently, the crushing shell in existing crusher chamber is generally in long slab
Shape, and upper part is higher by tup certain distance, therefore the part is within the scope of activities of tup, when the material that humidity is larger
It can be possible to fall on the top half of crushing shell after being struck by tup, easily stick in above, if things go on like this can be cumulative, it causes
The utilization rate of material is not high, and when the material of other properties is added, be easy to cause product sample mixing, product quality is caused to reduce.
2, in the crusher chamber of conventional breakers, grid section is installed together with body, stiff, granularity after hardness is larger and broken
When still larger material is among tup and grid section, the effect of being squeezed, material may be stuck in grid section hole, and humidity is larger
Material may block grid section, cause to shut down.
Invention content
The purpose of the utility model is to overcome defects existing for existing crusher, provide a kind of abundant broken material of energy,
It can be also effectively improved the hammer mill of material adhesion problems, which substantially increases production capacity and product quality.
The purpose of this utility model and to solve its technical problem realized using following technical scheme.It is new according to this practicality
A kind of hammer mill that type proposes, including casing, the cabinet top are equipped with material inlet.Be equipped in casing arc crushing shell and
Arc grid section, if the arc crushing shell opens up arterial highway groove on along the circumferential direction, the arc grid section and casing elastic connection are described
Around broken cavity is formed between arc crushing shell and arc grid section, which is connected to material inlet and lower section is equipped with material
Bucket；Crushing mechanism is equipped in the crusher chamber body, which includes rotor, which is equipped with several tups, the tup
Top is set as the fin with the groove match.
Further, the upper level of arc grid section is less than the height of groove slot bottom.
Further, twice groove is opened up on arc crushing shell.
It is further, fixed on rotor that there are four tups.
Further, rotor uniformly opens up several blind slots on along the circumferential direction, and the bottom of the tup is placed in blind slot
Portion is simultaneously fixed by axis pin.
Further, feed hopper bottom is equipped with pulley.
Further, the both ends of arc grid section are connect with bottom of shell by spring damper, and the spring damper top
Portion is welded with arc grid section, bottom and casing are affixed.
By above-mentioned technical proposal, the utility model proposes hammer mill at least have compared with prior art it is following
Advantageous effect：
1, the crushing shell of the utility model is arc-shaped, and grid section is also arc-shaped, then the arc crushing shell and arc are combed
It is surrounded between item and forms a circular broken cavity.The crusher chamber physical efficiency of this structure can allow completely not broken material
Movement improves the fragmentation quality of material up to being completely broken in destroyer body always.
If 2, opening up arterial highway groove on the arc crushing shell of the utility model, and it is provided on tup and coordinates with the groove
Fin.Crushing shell can be effectively scraped in tup high speed rotation, the two cooperates to realize the abundant broken of material
It is broken, wet material adhesion is also can avoid on arc crushing shell.
3, the arc grid section both ends of the utility model and casing elastic connection, when material movement to arc grid section, if combing
When material leakage is unsmooth or encounters the material for not being completely broken (granularity is more than grid section aperture after broken), grid section can be transported downwards
It is dynamic；Under the elastic force effect of spring damper, grid section can pop up recovery to original lumen type, in this shaking one on the other again
During dynamic, the material on arc grid section can be shaken, the satisfactory material of grain size is made to pass through arc grid section and from going out
Material mouth is discharged, and avoids the larger material of accumulation and adhesion and grain size of the wet feed at grid section and is stuck in grid section hole.
The above description is merely an outline of the technical solution of the present invention, in order to better understand the technology of the utility model
Means, and being implemented in accordance with the contents of the specification, and to allow the above and other purpose of the utility model, feature and excellent
