A jaw crusher machine has a double-acting jaw 110 that linearly reciprocates to reduce abrasive wear and tilts back and forth during the crushing and discharge strokes to create a peristaltic action that, depending on the direction of rotation of the driven shaft 118 , aids the ingestion, crushing and discharge of either hard or soft feed materials.
FIG. 1 is a cross-section and illustrates, schematically, a jaw crusher according to an embodiment of the present invention. FIG. 2 is a cross-section and illustrates, schematically, parts of the jaw crusher shown in FIG. 1. FIG. 3 is a perspective view and illustrates, schematically, a toggle plate squeezing device of the jaw crusher in FIG. 1.
Currently there are a number of solutions for crushing materials such as rock, gravel, coal, mineral ore and reclaimed concrete or asphalt. Some of these solutions are large, expensive, high capacity machines intended for continuous stationary use and permanent installation. These solutions fail to meet the needs of smaller-scale industries that require a small but sturdy and relatively inexpensive portable crusher that can be easily moved to different locations to quickly and reliably process smaller quantities of varied materials.
Machines designed primarily to crush hard materials often suffer from plugging when challenged to process softer materials such as reclaimed asphalt which, regardless of jaw material, can adhere to the crushing jaws as a sticky mass, particularly in warm weather. In either case, when such single-purpose machines eventually plug, they often require partial disassembly to clear the crushing chamber. As a consequence existing portable crushers are inherently limited in their ability to process a wide range of feed materials efficiently and at relatively low cost.
The path of motion of the moveable jaw relative to a fixed jaw can have either a positive or negative effect on jaw crusher machine operation, depending on the feed material. For example, the component of jaw movement perpendicular to the fixed jaw creates the compressive forces needed to break hard material such as rock and concrete. However, these compressive forces can also cause softer material such as reclaimed asphalt to adhere to the crusher jaws as a sticky mass.
U.S. Pat. No. 4,248,390 teaches a double-acting double-eccentric jaw crusher that completely eliminates vertical motion or tilting of the moveable jaw, thereby producing a fixed and uniform ratio of shear to compressive force over the entire crushing surface throughout the crushing stroke, and correspondingly uniform abrasive wear on the crushing surfaces. The crushing action is unaffected by the direction of driving shaft rotation. Although the design is effective for crushing hard materials, its motion is inflexible and does not provide the versatility to also handle softer materials.
The present invention advantageously fills the aforementioned deficiencies by providing a jaw crusher machine which has a crushing action easily adapted to break hard materials such as rock and concrete or crush softer material such as asphalt, which is resistant to plugging and easily cleared with minimal effort by the operator should plugging occur, and which minimizes jaw motions that abrasively wear the crushing surfaces or cause spit-back of feed material.
In accordance with another embodiment, the present invention may have first connecting rods connected at one of their ends to the eccentric and pivotally connected at their opposite ends to second connecting rods rigidly attached to the vertical jaw, the first connecting rods being pivotally supported at a point along their length by linear bearings that constrain said first rods to substantially horizontal reciprocating pivotal motion.
