Backfill attachment device

Abstract

A hole filling or blast hole filling attachment machine that incorporates a separate vehicle for mobility and power to operate dirt of drill tailing gathering blades and a rotatable blade assembly. The assembly includes a circular housing with a central opening for access to a drilled hole in the ground. No less than six arcuate blades extend outwardly from the center of the circular housing. Two curved dirt gathering blades are mounted with hydraulic cylinders outside of the circular rotating blades and protective housing to pull more tailings toward the arcuate blades. An electromagnet is used to retrieve the primer cord and to raise it up and away from the moving blades. The machine incorporates a video camera and video monitor to observe the hole or blast hole to allow the operator to correctly position the machine over the hole.

1 . A backfilling attachment device having the means to be attached or connected to a separate operating vehicle. This separate vehicle contains an attachable utility hydraulic system that connects by hose to a hydraulic motor mounted on the backfill attachment device. This hydraulic system supplies power to the new design horizontal rotating arcuate blade assembly. The said new design horizontal rotating arcuate blade assembly is constructed with an L shape or 90 degree angle and perpendicular cutting edge fastened to the outer end of each arcuate blade assembly. The said new design horizontal arcuate blade assembly includes a rotatable hollow vertical shaft disposed axially maintaining primer cord access through the central opening and housing around which the plurality of new designed arcuate rotating blades extend outwardly. This claim includes a mounted hydraulic motor that applies motion and enough force capable of pushing dirt or drill tailings by turning the hollow rotating shaft with attached arcuate blades. 
   
   
       2 . A backfill attachment device according to  claim 1  including a mounted video camera monitoring the said hollow vertical primer cord access shaft. 
   
   
       3 . A backfill attachment device according to  claim 1  with a video monitor mounted in said separate vehicle. 
   
   
       4 . A backfill machine attachment device according to  claim 1  including an electromagnet which can be controlled in and out of the hollow vertical shaft primer cord access shaft in order to magnetically attach to the metal primer cord recovery piece. 
   
   
       5 . A backfill machine attachment device according to  claim 1  with 2 attached dirt or drill tailing gathering blades that encircle said blast hole filling machine attachment device for the purpose of hydraulically pulling more dirt tailings toward center of machine to be used in backfilling the hole. 
   
   
       6 . A backfill attachment device according to  claim 1  with a protective covering safely housing the arcuate blade design.
