Definitions
- the invention relates to a jaw crusher, in particular in the form of a pendulum swing crusher or a crank swing crusher with oscillating crushing jaws arranged in a housing with at least one crushing compartment, fixed crushing jaws, setting of the crushing gap and a drive shaft with eccentrics and displacement.
- Such jaw crusher (DE-OS 1 607 514.2) have two crushing jaws, one of which is usually fixed and the other is arranged in an oscillating manner.
- the material to be crushed is crushed in the crushing compartment during the periodic closing of the crushing jaw, which swings around a pivot point, between the two crushing jaws, especially as a result of pressure, and falls after repeated use
- both crushing jaws are accommodated in separate crushing compartments, so that pieces of material which have larger dimensions than a crushing compartment cannot be comminuted in such units.
- Another disadvantage is that the drive shaft shown is very unfavorable to manufacture due to the spaced and circumferentially offset cams and, moreover, cannot be adapted to any changed requirements. Rather, the entire drive shaft then has to be replaced and the other components also have to be adapted so that changed operation is possible.
- DE-OS 199 56 200.8-23 has the same problems, only that despite two or three crushing jaws arranged next to one another, a continuous crushing compartment is now used, so that much larger individual pieces of material can be drawn into the crusher and shredded. If adjustments and changes are necessary, the drive shaft must also be replaced with a new one, which is also necessary if the corresponding wear has occurred.
- the invention is therefore based on the object of providing a jaw crusher which is simple to equip and convert with regard to the eccentricity and which only needs to be overhauled or supplemented with wear in relation to the individual parts.
- the drive shaft is designed as a rod which runs uniformly and which is releasably and interchangeably assigned to the eccentric designed as eccentric bushings.
- the exchangeable eccentric bushings are designed to be displaceable and rotatable on the drive shaft in the released state. Since, according to the invention, a continuous rod is used as the drive shaft, the individual eccentric bushes can each be easily pushed into the necessary working position, brought there in the circumferential direction into the intended position and then fixed in order to effectively perform their service.
- the invention provides that the eccentric bushings are releasably connected to the drive shaft via a tongue and groove connection. Seen over the circumference, several such tongue and groove connections can be specified, so that when the eccentricity is set, the user is given the opportunity to bring the eccentric bushes into an optimal position for their intended task.
- the invention provides that the eccentric bushes are designed to be detachably connected to the drive shaft and the swing tube assigned to the oscillating crushing jaw.
- the individual crushing jaw is thus preassembled so that it can also be attached to the eccentric bushes to connect the swingarm tube and bring it into the appropriate movement.
- the displacement of the drive shaft which is a continuous rod
- the displacement of the drive shaft has roller bearings assigned to the side walls of the housing and bearing supports with roller bearings arranged between the individual crushing jaws, a single continuous crushing compartment being realized.
- the continuous drive shaft is securely supported not only on the side walls over the length, but at the same time also on the spaced-apart bearing supports, which do not lead to a subdivision of the crushing compartment, but are only realized as bearing supports with roller bearings.
- the bearing brackets suitably have pillow block bearings to ensure the respective support and guide position for the continuous drive shaft.
- the roller bearings preferably the roller bearings assigned to the side walls
- the roller bearings are equipped with a labyrinth seal which have ring grooves fitted with O-rings with respect to the drive shaft.
- the O-rings and the safe arrangement of the O-rings in the ring grooves ensure that the lubricant stays exactly in the area where it is needed for the permanently safe guidance of the drive shaft. Long service lives of such devices are advantageously guaranteed by this special training.
- the total thickness of the walls of the housing can be kept within advantageous limits if the bearing supports are assigned compartment walls which divide the housing and which are designed to reach half the height of the side walls in the lower third.
- compartment walls in which the additional compartment walls are curved with the upper edge, the walls with the upper edge being curved, because in this way the optimal support is provided, but at the same time the separation by the Compartment walls can be placed at a point as deep as possible.
- the crushing gap of such crushers has to be adjusted due to wear, but often also for other reasons. For this purpose it is known to bring the adjusting wedge into the respective position and fix it with the aid of plates.
- the invention provides that, for automation and for a better execution of the entire shredding process, the setting of the crushing gap with its adjusting wedge has a hydraulic adjusting cylinder.
- the hydraulic adjusting cylinder ensures that the adjusting wedge is pushed into the corresponding position or raised, depending on whether you want to increase or decrease the crushing gap.
- the housing has a substructure with a compartment arranged between the longitudinal and cross members for the discharge conveyor and a gooseneck extension for the drive motor.
- a complete unit is then specified, with the crushed material leaving the crusher or the individual sub-areas of the crusher falling onto a discharge conveyor and being transported further by this, for example to a truck.
- the gooseneck approach enables the drive motor to be moved into one position bring where it is safely housed and can act safely on the drive wheels of the crusher, while the discharge conveyor is given an area where it can safely pick up and transport the crushed material without leaning on the ground.
- the invention provides that the discharge conveyor is designed to be pivotable, preferably 90 °, at the end of the substructure opposite the gooseneck neck, conveyor accessories being equipped with an additional, own pivoting device.
- the respective conveyor accessory part or several such parts are swiveled via the additional swiveling device in such a way that it is possible to swivel the corresponding swiveling end of the discharge conveyor practically up to 90 °.
- the compact transport unit is thus realized, which makes it possible to quickly return to the working position at the place of use so that the shredding work can be started quickly.
- Very large individual pieces can advantageously be gripped by the crushing jaws, because it is namely provided according to the invention that two or more vibrating crushing jaws, which are driven via the common drive shaft supported by intermediate bearings, in a common crushing compartment are arranged, wherein the crushing jaws can be moved intermittently via the common drive shaft.
- a common, continuous crusher housing or a crusher compartment is therefore provided for two, three or four crusher jaws. So far, the individual housings have been lined up with the crushing jaws, so that there are no large inlet openings, but many small ones. It is only with the help of the solution according to the invention that it is possible to pick up even large chunks to be broken and to effectively shred them without causing problems.
- the continuous drive shaft, to which the individual vibrating crushing jaws are assigned is supported via intermediate bearings in such a way that the more or less long drive shaft cannot be impaired.
- the crushing compartment with the drive shaft is arranged on a support frame in the longitudinal direction of the drive shaft and is provided with a complete housing or housing with material guidance for the material to be crushed.
- a jaw crusher of this kind can be moved from one place of use to another, whereby the complete housing ensures that imported mountains and other materials that are to be shredded cannot endanger the environment, so that one Jaw crusher can also be easily moved from one location to another. Separate security measures are then not necessary.
- the invention additionally providing that the eccentric bushings rotatably arranged on the eccentric cams can be connected to the eccentric cam and the associated rocker tube according to the desired eccentricity are trained to then quickly and safely start operating.
- the individual eccentric bushing can be rotated and shifted into a position which does not correspond to the neighboring one or which has a more or less larger eccentricity value, in order in this way with the same crusher to possibly also different crushed material at the same time , if there is a need to be able to manufacture.
- the invention is characterized in particular by the fact that a jaw crusher is created which, regardless of its particular design, can advantageously be constructed with respect to the eccentricity.
- the drive shaft is designed as a continuous rod and the eccentrics as eccentric bushings, which can be moved on the respective drive shaft and then rotated into the correct position in order to achieve the desired eccentricity. It is also possible to work similarly in the case of existing drive shafts provided with eccentric cams, namely by arranging the eccentric bushes on these eccentric cams and rotating them into the respective position in order to adjust the eccentricity in a targeted manner.
