MATERIL FEED DEVICE FOR GYRTORY CRUSHERS Patented Oct. 20, 1953 MATERIAL FEED DEVICE FOR GYRATORY CRUSHERS Alexander J. Roubal, Milwaukee, Wis., assignor to Allis-Chalmers Manufacturing Company, Milwaukee, Wis., a corporation of Delaware Application October 10, 1949, Serial No. 120,570
This invention relates to material feed devices, and more specifically to those devices used in conjunction with material crushing machines such as gyratory Crushers and the like. The principal object of the invention is the provision of new and improved feed devices of this type.
Heretofore in gyratory crushers, the material distributing means of the material feed devices were usually rigidly secured to the main crusher shaft. Hence every motion (including axial displacement) of the main shaft was directly imparted to the distributing means, which was undesirable.
When the clearance between crusher members was varied by vertically moving the main shaft to change the size of crushed material, clearance between the material distributing means and the material conveying means required a corresponding adjustment. This adjustment was necessary in order to maintain constant the flow of material into the crusher.
Sudden vertical displacements of the main shafts in prior art gyratory Crushers, due to tramp material caught between the jaws, caused corresponding vertical displacement of the material distributing means. This of course resulted in uneven and jerky feed distribution.
It is an object of the present invention to obviate the enumerated undesirable results characteristic of prior art gyratory crushers.
Objects and advantages other than those above set forth will be apparent from the following description when read with the accompanying drawing, in which:
- Fig. l is a vertical cross sectional view of the upper portion of a gyratory crusher embodying the invention; and
Fig. 2 is a vertical cross sectional view of another embodiment of the invention.
As shown in Fig. 1, the material crushing machine or gyratory crusher comprises a top frame 4to which is secured the rim l5 of a spider 6. The spider 6 has arms which extend radially inward and upward from the rim 5 and terminate in a bearing housing 1 concentrically positioned above a crushing chamber II, which chamber is defined by an inner crusher member or movable jaw 9 and an outer crusher member or stationary jaw Il); A gyratable shaft I 2 is fulcrumed in a suitable bearing such as a ball and socket type bearing, I4, I5s carried in the housing 1 and retained therein by a clamp ring I6 bolted to the bearing housing and the upper end of the bearing socket. The combination of rim 5, spider 6, bearing housing 1, and bearing 8 Claims. (Cl. 241--202) I4, I5 may be considered as a supporting struc-.-
ture for a material distributing means to be described hereinafter. I
Adjacent to the lower end of the bearing socke I5, and held between the bearing housing 1 and a bearing portion of the gyratable shaft I2, is
an oil seal I1 and a retainer I9, for preventingthe escape of lubricating oil, and for preventingy the entry of dust to the bearings.
The shaft I2 is gyrated at its lower end (not shown) by any suitable eccentric meansV and is supported to permit axial and rotary motion of which concentrically supports the wobble plate.
The opposite end of the cylindrical member 2I slidably coacts with the fulcrumed end of the gyratable shaft I2 to impart an oscillating or wobble motion to the wobble plate 26. The con. nection between the cylindrical member 2I and the shaft I2 may be termed telescopic. The spider 6 through the bearing housing 'I axially supports the material distributing means, for example by providing a at annular surface 24 on the bearing ball I4, for engaging in abutting re-y lationship the edge 22 of the cylindrical member 2|. Since the' peripheral edge of the wobble plate 20 is subjected to considerable abrasivey action from material flowing over it, a wearing ring 25 made of a relatively hard material, suchl as manganese steel or other suitable material.
may be secured thereto to prevent excessive wear.A
A resilient apron 26 of rubber or other suitable material, joins the material distributing means with the bearing housing 1. 'I'he lower end of the apron 26 is provided with a surface 21 transverse to its longitudinal axis, for engagement with a complementary surface on the bearing housing 1, and is fixed thereto by `bolts 28.
The opposite end of the apron 26 is formed with a surface 29 parallel to the cylindrical member 2l, and may be either secured thereto by vulcanization, or in any other suitable way, or fitted snugly thereto in a slidable manner. A Protec# tive flange 30 extending radially outward from the cylindrical member 2| is secured in any suitable manner, as by a weld 3|, directly above the cylinderapron vconnection to protect it from damage due to material which might otherwise impinge upon it.
A primary hopper 32 is secured to the spider rim 5 and extends upwardly above the level of the wobble plate 20. The upper edge of the primary hopper 32 is provided with a ange 34 for receiving a cover plate 35 secured thereon by any suitable means. An opening 36 is formed in the coverV 35 directly abovethe wobble plate for receiving therethrough a material'feed device comprising a material conveying means such as a vertically adjustable chute, designated generally by numeral 31, from which material is fed to the wobble plate 2B.
The rate at which material is fed to the crushing chamber Il is determined? by themean'distance between the lower endof the adjustable chute 31 and the wobble plate 20. The ygreater the distance, the more material-.will fall onnthe wobble plate 20 per unit time of operation, and conversely, the shorter the distance, 1 the less material will fall upon the wobble plate per uniti-of operation.
'With aipredetermined setting of: the: adjustable chute 3T, and with the shaft 4l2.".in'-its lowest possibi@position,l as indicated :by the :upperf surface 39feof1the shaft, .the operation of theniaterialI distributing vmeans is asifollows. As A:the Shaft gI2 gyrates, the fulcrumed end thereof, Whi'chfs'lidably engages the cylindrical .member 2l, will impart a gyratoryor oscillatory-'motion tothefwobbleplate.
"In al structurewherein .the apron '2 is fixedly secured tothe cylindrical -member 2l, the. apron will retain the material distributing means in .a nonrotative relationship with respect to the spider Spand at' thelsame time will preventupward axial displaeementvof the material distributing'means 202with respectV tothe spider@ Hence vthe rotational motion -of the gyratable shaft I2 about its own axis, vrand'the axial displacements ofthe shaft, :forexample` to its uppermost 1position=as indicated-by dotdash'lim-zl A0, are `not transmitted to itheimate'ria'lfdistributing'mean 20.
The hereinbefore mentioned alternative structure,- wherein the2apron'26 is'merely-tted snugly about the cylindrical member2 l, will permit rotation of the material d-istributing meansLZ if the rotational frictionalfforce between the shaft 'I2 and VtheJv cylindrical 'member 2| becomes' great enou'ghto overcomev the inertia Vof the mass .of materialresting on the wobble zplatey 20. `Irrsuch a structure the clearance betweentheT shaft `I12 andthe-cylindrical member!! is sunicient Vto allowaxial displacement of the shaft without (xausingVV axial displacement of the' materiali distributingfmeans. i Hence the :material will be distributed-uniformly to :the crushing chamber I I in accor-dancerwith` thebbjects .of the invenion.
"FigffZ-shows another embodiment-.of the .invention inf which *like elements aredesigna-ted by the= same reference characters as in Figi l with the= addition yof the suffix t'11. In this instance-1a resilient member such asl an` invertedlapron 24|, which lmaybe'A substantially Ycylindrical .or ofY any otherfsuitable shape, joins the material distributing means :to a Abearing cap 42 carried-by the bearing housing'la. VThe'lower end of the inverted apronlllis provided with atransverse .section 44 secured to a-corresponding flat surface vofthe capidzzlby boltsi45. TheY opposite end has a simiiaritransverse .section :16 -slidably held'to the underside of the wobble plate-20a adjacent to its periphery :bya lip portion 49 of .an annular :member-.41 `which is suitablysecured .to the 'wobble plate.
The operation of the embodimentof the'initfwill also be obvious to those skilled in the art that. theillustrated .embodiments of the invention maybe variously changed and modified, or
features thereof, singly or collectively, embodied vin:.o`ther -combinations than those illustrated, A'without' departing from the spirit of the invention, -or`V sacrificing' all of the advantages thereof,,and. .that accordingly the disclosure herein is illustrative only, and the invention is not limited thereto.
