Spring loaded pick
View Patent ↗In one aspect of the invention, an apparatus for degrading natural and man-made formations includes a pick with an axially spring loaded pick comprising a central axis and being attached to a holder secured to a driving mechanism. The pick comprising a steel body with an axial shank disposed within a bore of the holder.
1. An apparatus for degrading at least one of natural and man-made formations, comprising:
an axially spring loaded pick attached to a holder, wherein the holder is secured to a driving mechanism, the pick including a steel body with an axial shank extending rearward from a base of the steel body, the shank including a rearwardly positioned flange is press fit within a movable carrier of the holder, the carrier including indents, and the holder including fingers that interface with the indents and limit the axial movement of the pick;
wherein a tip of the pick is brazed to a carbide core press fit within the steel body;
wherein the tip includes a diamond material with a thickness of at least 0.100 inches and including a 0.050 to 0.200 inch apex radius;
wherein the carrier is also spring loaded by a spring mechanism.
2. The apparatus of claim 1 , wherein the driving mechanism is a drum, chain, wheel, or combinations thereof.
3. The apparatus of claim 1 , wherein the material of the tip comprises a 6% to 20% by volume concentration of a metal binder.
4. The apparatus of claim 1 , wherein the spring mechanism is built into the holder.
5. The apparatus of claim 1 , wherein the spring mechanism comprises, a coil spring, a compression spring, a tension spring, Belleville spring, wave spring, elastomeric material, gas spring, or combinations thereof.
6. The apparatus of claim 1 , wherein the driving mechanism is attached to a motorized vehicle.
7. The apparatus of claim 6 , wherein a dampening element is attached to the motorized vehicle and is adapted to vibrationally insulate the motorized vehicle from the driving mechanism.
8. The apparatus of claim 7 , wherein the dampening element comprises a shock.
9. The apparatus of claim 6 , wherein the motorized vehicle is a trenching machine.
10. The apparatus of claim 1 , wherein the spring mechanism is disposed between the steel body and the holder.
11. The apparatus of claim 10 , wherein the spring mechanism is a Belleville spring.
12. The apparatus of claim 1 , wherein the carbide core extends a majority of a length of the steel body into the steel body.
