摘要:
In the auger cleaning device (8) according to the invention, in the closed configuration the tool-holder support forms a pass-through opening (82) arranged for allowing the passage of a helical drilling tool (6), the cleaning tool (170) engaging with the screw of the drilling tool (6) and, actuated by the actuation system (12, 12′,12″, 4), is arranged for rotating around the drilling tool (6) following at least one of its threads (60) so as to remove the debris lying on the drilling tool (6). In the open configuration the cleaning tool (170) is disengaged from the drilling tool (6) and preferably farther from it, with respect to when it is in the closed configuration.
摘要:
A soil surface remediation apparatus useful for decontamination of oil or chemical spill sites and toxic waste containing sites comprises a soil treatment apparatus mounted on a mobile trenching machine tractor which excavates trenches in a contaminated site to remove contaminated soil to the surface apparatus where the soil is decontaminated and is immediately replaced into the excavated trench in a continuous operation. Hydrocarbons or other useful by-products such as precious metals may be recovered from the soil. Both deep trenching and shallow trenching embodiments are disclosed.

An attachment for operation by a conventional tractor having the three arm support or similar attachment means and a power takeoff which support and drive a material removal machine which is power-driven by the power take-off. The material removal machine includes a screw which moves the material from the sides towards the center into a centrifugal blower which disposes of the material. The attachment also includes driving wheels which engage the driving wheels of the tractor and which is driven by an infinite control speed changer to drive the tractor wheels in either a forward or reverse direction at extremely slow speeds, whereby the material removal machine can be moved toward the material such as a snow bank at the very slow speed to provide maximum efficiency of the equipment. An ice breaker is mounted on a horizontally extending shaft and has teeth which are swingable to break the ice. A ditch excavating attachment is adapted for mounting on the material removal machine and driven thereby taking advantage of the slow movement of the tractor by the infinite speed adjustment. This arrangement provides for slow speed movement of the tractor with maximum speed of the material collecting, processing and blowing means and also of the ditch digging attachment. The attachment also provides an auxilliary power take-off for spraying equipment and the like. Also by simple exchanging of other shafts for the collector screw and/or ice breaking shaft, a myriad of other functions can be efficiently performed, such as lawn raking, sweeping and vacuuming, rototilling, harvesting, aeration, etc.
摘要:
A vehicle having a long track or wheel-trail wheel combination on one side and a smaller ground engaging member, such as a short track or wheel on the other. The vehicle has a work attachment on one end of as frame, which is provided clearance on the side of the vehicle with the short track or wheel. A control system is provided to allow an operator to properly control a direction of the vehicle despite the fact that different forces may be required to operate the long track and the short track or wheel.

摘要:
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.
摘要:
A digging boom assembly including a first section which is attached to a trencher and a second section that may be disconnected from the first section and replaced with another identically configured section of longer or shorter length. The boom assembly is attached to the trencher such that the first section always remains connected to the trencher while the second section may be selectively exchanged with another section of a different length thereby permitting variable digging depths. An auger attachment and a crumber attachment are connected to the first boom section, which remains attached to the trencher at all times. Thus, when the second boom section is disconnected and replaced with another section of longer or shorter length, the auger and crumber attachments do not have to be disassembled from the boom assembly.
摘要:
A digging chain for a trencher with a repeated pattern of single-piece toothed links, The single-piece teeth are pivotally connected on each side to an adjacent link. The single-piece teeth comprise a repeating pattern with the first and second teeth having different shapes on the same side of the digging chain, and the third and fourth teeth are on an opposite side of the digging chain.
