ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to stonecrushers and, more specifically, to stonecrushers with an externally adjustable anvil ring that can be raised or lowered incrementally during operation to provide even wear on the anvils.
2. Description of the Prior Art
There are numerous stonecrushers which provide for the fragmentation of rocks. While these stonecrushers may be suitable for the purposes for which they where designed, they would not be as suitable for the purposes of the present invention as heretofore described. It is thus desirable to provide a stonecrusher with an externally adjustable anvil ring that can be raised or lowered during operation to provide for even disintegration of the anvils caused by the impact of the stones being crushed. It is further desirable to provide a stonecrusher that utilizes the material being pulverized to protect components of the apparatus from the impact of the hurtling stones.
SUMMARY OF THE PRESENT INVENTION
The present invention discloses a device for crushing stone having an externally adjustable anvil ring. The anvil ring is contained within a drum and has multiple lifts mounted on hydraulic support members which can be adjusted from a control panel either manually or automatically. The anvils are spaced about the anvil ring so that the face of the multiple anvils are perpendicular to the line of travel of the stones. The anvils have anchors for attachment to the anvil ring whereby the worn anvils can be easily inverted so as to prolong anvil life.
The present invention relates generally to stonecrushers and, more specifically, to a stonecrusher with an adjustable anvil ring which allows an operator to adjust the height of the anvil ring without having to disassemble the unit. This will permit the operator to make adjustments without shutting down operation.
A primary object of the present invention is to provide a stonecrusher with an externally adjustable anvil ring which will overcome the shortcomings of prior art devices.
Another object of the present invention is to provide a stonecrusher with an adjustable anvil ring that has anvils that are angled to directly receive the impact of the stones and increase the efficiency of the apparatus.
Another object of the present invention is to provide a stonecrusher with an adjustable anvil ring whereby the anvils are arranged to form a stepped cylinder with comers to accumulate stone fragments that will receive the impact of the shattering projectiles thereby reducing the wear of the anvil heads.
A still further object of the present invention is to provide a stonecrusher with an adjustable anvil ring that will contain a 90-degree lip at the end of each propulsion wall in the centrifugating head. Material will be forced against the lip and accumulate along the propulsion wall as the centrifugating head spins. The stone introduced into the head will then strike the accumulated material rather than wearing down the propulsion wall.
Another object of the present invention is to provide a stonecrusher with an adjustable anvil ring that can move the anvil ring at a pre-determined rate according to the amount of stone that has passed through or could be set by timer.
Additional objects of the present invention will appear as the description proceeds.
To the accomplishment of the above and related objects, this invention may be embodied in the form illustrated in the accompanying drawings, attention being called to the fact, however, that the drawings are illustrative only, and that changes may be made in the specific construction illustrated and described within the scope of the appended claims.
