Description
Technical field：
The present invention relates to a kind of hammer mill, belong to mining machinery technical field.
Background technology：
Hammer mill is a kind of impact crusher conventional at present, with productivity ratio is high, reduction ratio is big, simple structure, body
The advantages of type is compact, easy operation is repaired and power consumption is less.When hammer mill works, broken material is carried out mainly by impact energy,
Now, motor rotor driven carries out the rotation of high speed, while material enters in the chamber of disintegrating machine from charging aperture, so returns at a high speed
The tup turned can impact, shearing splitting material crushes it.The casing of disintegrating machine includes upper box and lower box, and casing has stop
The effect that comminuting matter splashes to periphery, so the material and thickness of casing need to can guarantee that casing is not easy the crushing splashed
Material is broken up.Material after broken is dropped on the sieve plate below rotor, and particle diameter leads to less than the grade of screen size in comminuting matter
Sieve plate discharge is crossed, the coarse fraction more than screen size is then stayed on sieve plate, while also there is the irregular comminuting matter of some particle shapes
It is stuck in sieve aperture, blocks sieve aperture, causes to hoard on sieve plate by the comminuting matter of sieve aperture originally.If sieve need to be continuing with
Screen selects fine-graded crushed material, then needs the coarse fraction comminuting matter that will be accumulated on sieve plate and the crushed material being stuck in sieve aperture
Material takes out, and sieve plate is continued normal work, completes such processing procedure and usually requires to lay down the upper box of disintegrating machine,
Sieve plate can be just touched, sieve plate is cleared up.The cracking cabin of conventional breakers and crusher shell are an entirety, and inconvenience is thorough
Cracking cabin is cleared up at bottom, and the replacing to some parts of disintegrating machine inside is also inconvenient, and the time of each maintenance is long, maintenance difficulty
Greatly.
Clearing up the concrete operations of sieve plate is：The connecting bolt of lower box is removed, upper box is laid down, but box weight
Greatly, directly upper lower box can not be separated by manpower, it is necessary to there is crane gear to complete to lay down the work of upper box.Due to clear
The frequency for managing sieve plate is high, and cleaning work not only spends the time, delay production, while also expending substantial amounts of human and material resources, makes production
Cost is further improved, and Business Economic Benefit is brought and had a strong impact on.Therefore in the urgent need to the structure to disintegrating machine is improved,
The problem of to solve to need to unload upper box during cleaning sieve plate.In hammer mill, tup due to constantly abrasion, the flat side of a hammer with
The distance between sieve plate can constantly increase, and not only influence the size of material particles, and can reduce the operating efficiency of disintegrating machine.Cause
This needs usually to change tup, increases production cost, increases the labor intensity of machine repair personnel.Tup is changed in order to reduce
Number of times, reduces production cost, people are mounted with sieve plate adjusting means on disintegrating machine, because structure is not reasonable, in adjustment sieve
Between plate and tup apart from when, sieve plate easily anti-raw vibration causes the junction between sieve plate adjusting means and sieve plate to occur disconnected
Split, reduce the service life of sieve plate adjusting means.It is equidistant on the hammer disk of hammer mill that several canopy bars are installed, it is used for
The larger stone of support volume, prevents from accumulating shock of the larger stone to hammering disk into shape.Existing canopy bar is generally vertical bar shaped, causes tup
Crusher chamber rear portion building stones can not be impacted, and it is pliable easily broken, and service life is short, changes difficult, influences the work of hammer mill
Make efficiency.In order to be able to make tup to impact the building stones at crusher chamber rear portion, our company has invented a kind of broken canopy in 2012
Bar, Patent No.：2012205158323, including：Main body, the two ends of the main body carry locating piece, the radian of main body
Broken canopy bar described in basis corresponding with radian in crusher chamber, generally one square bar of the main body is broken according to described
Broken canopy bar, the material of the main body is austenitic manganese steel casting square steel.It is an advantage of the invention that：The two ends of main body carry locating piece, can
Make canopy bar more convenient when fixing, be fixed up and more consolidate, the radian of main body is corresponding with radian in crusher chamber, can make hammer
Head can impact the building stones at crusher chamber rear portion.But it occur frequently that the phenomenon of spoil pile above this kind of broken canopy bar, and
And it is heavier, former and later two locating pieces easily wear and tear during use, cause the service life of whole canopy bar and reduce, because
This, it is necessary that existing broken canopy bar is improved.
The content of the invention：
It is an object of the invention to provide one kind it is rational in infrastructure, easy to operate, long service life, high working efficiency, crushing effect is good
Hammer mill.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：
A kind of hammer mill, including casing, runner, tup, rotor disk, canopy bar, sieve plate, rib, it is characterized in that：The casing
The bottom of front-back is respectively provided with a door, i.e., preceding door and rear door are easy to thorough cleaning cracking cabin and maintenance box house
Part.A runner is respectively provided with the left and right sides of casing, using double runner structure, slow-roll stabilization can improve crushing efficiency.
Rotor disk sheath is installed on the periphery of the rotor disk, abrasion of the material to rotor disk periphery, Extending Rotor can be reduced
The service life of disk, improves the quality of product.The canopy bar is arc, and its material is potassium steel, including supporting part, preceding connecting portion
With rear connecting portion, supporting part is arc, and preceding connecting portion is provided with the front end of supporting part, is connected after being provided with the rear end of supporting part
Portion.The canopy bar of arc can prevent from accumulating building stones above canopy bar, improve the operating efficiency of hammer mill.The sieve plate is split type
Sieve plate, is made up of former and later two arc screening plates, and it is semicircle that former and later two arc screening plates, which constitute the cross section of sieve plate,.In sieve plate
Outside rib is provided with several equidistant bolts hole, and a regulating bolt is installed on each bolt hole, is adjusted by rotating
Save the distance between bolt adjustment sieve plate and tup size.Several equidistant connections are welded with the inner surface of the rib
Post, connecting pole is stretched into the sieve aperture of sieve plate, has both prevented that sieve plate from rotating, and sieve plate can again moved back and forth along connecting pole, is conveniently adjusted
The distance between sieve plate and tup size, can improve the operating efficiency of hammer mill.
The beneficial effects of the invention are as follows：It is rational in infrastructure, easy to operate, long service life, high working efficiency, crushing effect
It is good.
