摘要： An improved design for a dust shroud providing an airflow conduit for collecting dust off a work piece and a saw blade is disclosed. The dust shroud is configured with either one or two extending and telescoping lower rigid jaws that are durable and can engage a work piece at different angles. A novel roller is additionally provided for moving along a work piece.

摘要： A core drill or a grinder power tool design is disclosed herein also incorporated to a dust collection apparatus. The tool has a motor portion and a shaft portion, the shaft portion being characterized by a hollow shaft together with a casing forming a conduit for the dust created during coring or grinding applications. A harness is provided to the collection apparatus and the overall design is portable and functional right-handed or left-handed. A ring gear configuration is provided to transfer shaft power at a right angle. Further, several bearings are introduced to align shafts and absorb thrust created while applying pressure to a work piece. Power is additionally supplied to the power tool via a special modification to the collection apparatus.

摘要： Aspects to facilitate dust collection are disclosed. In one aspect, a chute provides a dust seal between a bulk bag of material and a silo loading hatch. Here, the dust seal comprises a first seal between a first end of the chute and the bulk bag, and a second seal between a second end of the chute and the silo loading hatch. In another aspect, a collapsible chute is extended between a silo loading hatch and a discharge chute of a bulk bag such that the collapsible chute forms a dust seal between the silo loading hatch and the bulk bag. Contents of the bulk bag are released via the discharge chute so that the contents of the bulk bag flow into the silo loading hatch. For this embodiment, the dust seal prevents airborne dust associated with the flow from escaping into an exterior portion of the collapsible chute.

摘要： A chop saw, grinding wheel, or like apparatus is disclosed herein also incorporated to an easily portable dust collection system. In a preferred embodiment, a worktable is provided with a center slot for receiving a circular saw blade. A negative pressure and resulting air flow is provided at the center slot to capture particulate matter as a byproduct of cutting the workpiece. Side slots are also disclosed to assist in particulate collection. A unique filter chamber having a cylindrical filter is additionally provided to remove dust from air and discharge the filtered air at a lateral side of the apparatus. A filter cleaning knob is additionally disclosed to assist in cleaning the filter. Of the beneficial aspects of the chop saw with dust collection system is its portability being one integral unit and the dust filter being easily cleaned and maintained.

摘要： Aspects for dust collection are disclosed. In one aspect, an apparatus is disclosed, which includes a lightweight portable housing such that a vacuum source, a filter component, and a dust containment component are housed within the lightweight portable housing. The apparatus further includes an input component configured as a conduit between the lightweight portable housing and a dust transition area corresponding to an area between a dust loading component and a dust receiving component. The vacuum source is configured to apply a negative pressure to the dust transition area by creating an air flow from the dust transition area to the lightweight portable housing via the input component, whereas the dust containment component is configured to collect airborne dust removed from the dust transition area and filtered by the filter component. Similar apparatuses are also disclosed to facilitate dust removal from a silo, as well as from a mixer.

摘要： Various dust collection apparatuses are disclosed, which include a vacuum source, a circular saw blade, and a worktable comprising a center slot axially aligned to the circular saw blade. In a first aspect, the center slot includes an air flow channel proximate to an anticipated point of contact between the circular saw blade and a workpiece, and the vacuum source is configured to provide a focused negative pressure beneath the worktable via the air flow channel. In another aspect, the vacuum source provides a negative pressure beneath the worktable at the center slot, and a multistage filter is included to collect airborne dust drawn by the negative pressure from an area proximate to the center slot. In yet another aspect, the vacuum source is configured to provide a first negative pressure beneath the worktable at the center slot, and a second negative pressure via an auxiliary port.
