Deep basement excavation system and truck loader

摘要

An apparatus for the excavation of a deep basement includes at least two main auger assemblies that are disposed vertically with one assembly atop the other. Auger blades in each assembly are operatively connected together. A feed hopper attached to a bottom of the lower main auger assembly conveys excavation material through a feed hopper opening to the auger blade for lifting. A steel ball is attached to a bottom of the auger blades. The ball rests in a spherical recess and acts as a thrust bearing. A discharge opening is provided proximate a top of the uppermost main auger assembly. A pivoting discharge chute is located at the discharge opening. During use, excavation material is loaded into the feed hopper, conveyed to the auger blades, lifted by the auger blades, discharged through the discharge opening, down the discharge chute and into a dump truck bed for removal.

主权项

1. A deep basement excavation system and truck loader, comprising:
(a) at least two main auger assemblies, wherein said at least two main auger assemblies include a lower main auger assembly and an upper main auger assembly; (b) means for securing said upper main auger assembly to said lower main auger assembly, wherein a center longitudinal axis of said lower main auger assembly aligns with a center longitudinal axis of said upper main auger assembly and wherein said center longitudinal axes are vertical; (c) an auger blade disposed in a casing of each of said main auger assemblies, wherein said casing includes a hollow cylindrical shape, and wherein said auger blade includes a drive rod and a spiral blade attached to said drive rod, and wherein said drive rod extends along a longitudinal length of each of said main auger assemblies; (d) means for operatively connecting a bottom of said auger blade of said upper main auger assembly to a top of said auger blade of said lower main auger assembly; (e) means for rotating said drive rod and said auger blade sufficient to lift a quantity of excavation material from a bottom of said lower main auger assembly to a top of said upper main auger assembly; and means for supporting the weight of said at least two main auger assemblies and said means for rotating said drive rod and said auger blade and any of said excavation material disposed along said longitudinal length of each of said main auger assemblies.
