Inventors:
Gregory A. DeWind - Zeeland MI 49464
International Classification:
E02F 365
US Classification:
37362, 37380
Abstract:
A shaft driven trencher including a mobile powered base, a boom assembly, a chain digging assembly, a drive assembly and a linkage. The boom assembly includes a first boom member pivotally mounted to the base at a first pivot and a second boom member pivotally mounted to the first boom member. The chain digging assembly has a plurality of buckets. The drive assembly operably interconnects the mobile base and the chain digging assembly, with the drive assembly including a drive shaft connected to the mobile base for powered rotation of the drive shaft. The drive assembly further includes a right angle gear unit with input and output shafts, with the right angle gear unit being pivotally mounted to the boom assembly for rotation about the output shaft. The linkage interconnects the right angle gear unit with the base and pivots the right angle gear unit during rotation of the first boom member. The linkage also maintains the input shaft of the right angle gear unit facing the first pivot.

System And Method Of Forming An Underground Slurry Wall

US Patent:
2014006, Mar 6, 2014
Filed:
Sep 5, 2012
Appl. No.:
13/604549
Inventors:
Gregory Allen DeWind - Zeeland MI, US
International Classification:
E02D 3/00, E02F 5/02
US Classification:
4053024
Abstract:
A method of forming an underground slurry wall having the steps of: (a) providing a trencher having a trenching arm assembly with a cutting tooth track; (b) providing a dispensing tube proximate the cutting tooth track; (c) rotating the cutting tooth track; (d) extending the cutting tooth track below the outside surface, to, in turn, agitate the soil therebelow to a predetermined depth; (d) translating the trenching arm assembly across the outside surface so as to form an underground wall of agitated soil; (e) dispensing a clay-like material proximate the cutting tooth track; and (f) utilizing the cutting tooth track to mix the clay-like material into the soil while the cutting tooth track is rotating and translating, to, in turn, mix the clay-like material into the agitated soil. Systems are likewise disclosed.
