Abstract
ABSTRACT
A crushing device has a rotator with striking tools, and a cylindrical roller as a counter tool. The rotator is mounted in a swivel frame, the height and longitudinal direction of the swivel axis of which can be varied for changing the gap between the rotator and the roller. The swinging movement of the swivel frame is limited by limit devices provided with cushioning elements. A cylinder filled with pressure medium exerts an essentially constant biassing force on the swivel frame in the direction toward the roller.

Description
~L~''3~
The present inventi.on relates to a crushing device having: a multi-armed rotator, which is provided with striking tools which are swingi.ngly suspended about axes which extend para:llel to the axis of rotat:ion of the rotator; and a counter tool which is provided with a circum:~e:rent.ially cl.osed peripheral surface.
Wi.th one known crushing devite (~1. Schuhert: Aufberitung fester minera:Lischer RohstoffeJ Vol. 1, 2nd ~clition, Leipzig 196~, V~B Deutscher Verlag :~ur Grundstoffindustrie, P~ge 1l~), a rotator which is provided with stri.king tools cooperates with a breaker plate which has a certain orientation to the rotator and, analogous to the endless track of a track laying vehicle, is guided around two shafts and is supported on a straight guide. With this known crushing device, there is no possibility of shifting the rotator to allow larger pieces in the feed material which cannot be crushed~ such as stone, iron, or wood, to pass. As a ma~ter of fact, when such pieces are encountered, there is a danger that the rotator can hecome clogged and even damaged and jammed, especially at a high throughput of material.
It is an object of the present invention to provide a crushing device of the aforementioned general type for soft to moderately hard material, in which device the passage gap between the rotator and the counter tool can be easily altered, and in which larger pieces which cannot be crushed can pass without obstruction.
Summary of the Invention The present invention provides a crushing device, comprising: a multi-armed rotator which is rotatable about an axis of rotation; striking tools associated with said rotator and swingingly suspended abou~ axes which are parallel to said axis of rotation of said rotator; a swivel frame which 8~
~ .
i.s pivotable about a swivel axis which is parallel to and above said axis of rotation of said ro~.ator; said rotator being mounted in said swi.vel frame; and a counter-tool which is provided with a circumferen-tially closed peripheral surface.
Due to its generally consi.clerable weight, ~he rotator is essentially suspended below the swivel axis and is spaced at a certain distance from the counter tool. When larger pieces which cannot be crushecl are encountered, the swivel fr~me, l~ith the rotator, can swi.ng away, in which connection the we:ight of the rotator acts as a ret~rn force and returns the rotator to its original position.
To ensllre that after the deflection the rotator does not strike the counter tool, the crushing device may be provided with adjustable limit devices which fix the end positions in the range of movement of the swivel frame. With these limit devices, as small a gap as desired can be set between the rotator and the countcr tool. This can especial~y occur if the swivel frame rests against the limit devices beyond the lower position.
To avoid unnecessary stress, each limit device may be provided with a cushioning or damping element. To supplement the return force~ the swivel ~rame of the crushing device may be connected with a device which applies an essentially constant biassing force in the direction of the counter tool.
Further possibilities f.or adjusting the gap between the rotator and the counter tool, and hence for achieving a speci~ic ~inal granular size, re-sult from various designs of the crushing device. For example, the height of the swivel a~is may be adjustable. Also, the swivel axis may be horizontally adjustable in the :Longitudinal direction.
When the fed material is discharged ~rom the conveyor belt, it may Bl~
fall upon a coun~er tooJ which is in the form of a cylindrical roller, and where~ due to ~he lcinetic energy converted as a result of the impact, it under-goes a preliminary crushing. If the counter tool, i.e. the roller, has other than a smooth cylindrical surface, not only is a better crushing action achieved, but a be~ter drawing-irl into the region of the rotator is also achieved.
Advcantages of the present invention, will appear more clearly from the following specification in connection with the accompanying drawings, iJl which:
~ igure 1 is a schematic illustration o one inventive embodiment of a crushing device having a feeding roller and a four-armed rotator which is suspended in a swivel frame;
Figure 2 is an enlarged cross section o the swivel frame with the rotator taken along the line II - II in Figure 1;
Figure 3 is a partial cross section o ~he swivel frame and the drive of khe rotator taken along the line III - III in Figure 2;
Figure ~ is a side view of a device for adjusting the height of the swivel axis of the swivel frame;
Figure 5 is a plan view of the device for changing the position of the swivel axis in a horizontal direction;
Figure 6 is a side view of a ~eeding roller having profiled plates;
Figure 7 shows a feeding roller which is provided with strips which are arranged transverse on its surface; and Figure 8 shows a feeding roller which is provided with protuberances located on its surface.
Referring now to the drawings in detail, below a belt feeder 1 is disposed the receiving and crushing chamber 2 of the crushing device; a feeding roller 3 and a rotator 4 are located in this chamber 2.
The surface of the feeding roller 3 is covered with smooth wear plates 11. The fecding roller 3 is dr:ivell by a motor (not shown~ in such a way that the surEace thereof which a-t any given time i.s at the to~p is moved in the direction toward the rotator 4. A chute 12 is mounted above the ro:l:ler 3 on that side thereo~ remote ~rom the rotator 4; the chute 12 prevents escape of the :t`ed material ahead of the rotator ~l. In order to increase the gr:ipping capacity, the surface of the roller 3 can be provided with profiled wear plates 13 ~Figure 6), with strips 14 which extend over the entire width of the roller 3 (~igure 7), and/or with individual protuberances 15 ~Figure 8).
The rotator 4 has four arms 16 which comprise individual plate sec-tions 17 between the ~ree ends of which striking tools 18 are pivotably mounted on pins 19. The pins 19 are parallel to the axis o:E rotation 20 of the rotator 4, and are respectively arranged at the same distance therefrom. As a modifica-tion of the described embodiment, the rotator 4 can7 depending upon its applica-tion, also be provided with six arms.
The entire rotator 4 is suspended in a U-shaped swivel frame 5 which is formed by two laterally arranged side plates 22, and horizontal and vertical reinforcing plates 23 and 24 respectively. The upper part of the swivel frame 5 is provi.ded with a shaft 25, the center line of which coincides with the swivel axis 26 of the swivel frame 5; the two ends of the shaft 25 are supported in bearing housings 27.
The bearing housings 27 are respectively located between two vertical guides 28, and their height is ~ixed and maintained by a guide carrier 29.
The guide or curve carrier 29 has two curve or guide parts 30~ 31 which are held together by connectors 32. The actual curves of the curve parts 307 31 are straight and extend at an angle. They are equipped with wear strips 33. The lower curve part 31 has an extension 34 of its cross-sectional area which allows horizontal movement on a subframe 6. To guide the curve carrier 29, a wear strip 35 and holding mecms 36 fastened on the subframe 6 are addi-tionally provided. The bearing housings 27 have laterally perpendicular outer surfaces 373 with which they rest against the guides 28, and above and below have inclined outer surfaces 38 with which they slide along the wear strips 33.
In order to horizontally displace the guide or curve carrier 29, a hydraulic cylinder 40 is provlded on each side, the piston rod 41 of which is linked to the curve carrier 29, and the cylinder housing of which is linked to a bracket 42 which is fastened to the subframe 6. By changing the position of the piston of the hydraulic cylinder 40, the height of the swivel axis 26 is correspondingly changed and fixed. ~hanging the height of the swivel axis 26 presents a possibility for changing the distance a (Figure 1) between the roller 3 and the rotator 4.
The subframe 6 has four rollers 43 by means of which it is movable in the longitudinal direction on guide rails 44 (Figure 2) which are arranged on both sides. To fix the position of the subframe 6 to ~he stationary guide rails 44, a hydraulic cylinder 45 (Figure 5) is provided, the piston rod 46 of which is linked to the crossbeam 47 of the subframe 6, and the cylinder housing of which is linked to a crossbeam 49 which is connected -to the guide rails 44.
As shown in Figure 3, the other end of the subframe 6 also has a crossbeam 50, which is provided with a limit device 51 comprising two clamping pieces 53a and 53b7 and a ram 54. The clamping pieces 53a and 53b are loosened and tightened with the aid of a screw coupling 55. The ram 54 of the limit device 51 serves to limit the left position of the swivel frame 5~ that is, the direction which faces the feeding roller 3. To avoid severe impacts~ -that end oE the ram 54 which is across from the side plates 22 is provided with a cushioning elemen-t, for example a rubber block 56.
To provide uniEorm stressing" separate limit devices 51 and 52 are provided for each sicle plate 22 o-f the swivel frame 5. As a variation of the embodiment described above, the limit devices can also be provided with hydrau-lic shock absorbers.
A hydraulic cylinder 57 ls respectively arranged between the subframe 6 and each side plate 22 of the swivel frame 5. The piston rod 58 of each hydraulic cyli-nder 57 is lin~ed to a side plate 22, and the housing oE the hydraulic cylinder 57 is linked to a bracket 59 of the subframe 6. Both hydraulic cylinders 57 are connected with a hydraulic reservoir or accumulator 60, the holding capacity of which is considerably greater than the chamber volumes of the two hydraulic cylinders 57. As a result, an essen~ially con-stant horizontal force is exerted upon the swivel frame 5 in the direction to-ward the feeding roller 3 nearly indepe-ndently of the actual swivel position of the swivel frame 5.
An electric motor 61 having a hydraulic clutch (not shown~ is pro-vided for driving the rotator 4. The motor 61, with its pulley 62, via a first belt 63, drives the pulley 64a of a pair of pulleys, the second pulley 64b of which, via a further belt 65, drives the pulley 66 which is mounted on the shaEt of the rotator 4. In order to take into account the change of the re-quired length of the belt 63 when the height of the swivel frame 5 is adjusted, a further pulley 67 is provided for the first belt drive. The pulley 67 is pressed against the lower run or side of the belt 63 with the aid of a lever 69 and a torsion rod 68 which is mounted to the subframe 6. The speed of the motor 61, and the transmission ratio o:E the belt drive, are selected in such ~ way that the speed of the rotator 4 is a multiple of the speed of the roller 3.
The present invention is~ of course, in no way res~ricted to the dis-closure of the specification and drawings~ but also encompasses any oodif:ica tions within the scope of the appended claims.
