A stripper packer coupling assembly can include a packer operable to receive a tubular therethrough and form a seal about the tubular. The packer can comprise a plurality of coupling protrusions, each having a coupling head defining a first capture interface. Additionally, the stripper packer coupling assembly can include a capture mechanism. The capture mechanism can comprise a guide member having a plurality of guide openings, each operable to receive one of the plurality of coupling heads therein. The capture mechanism can also comprise a plurality of capture members, each defining a second capture interface. Capture members can be operably coupled to one another such that they are simultaneously movable relative to the guide member and the coupling protrusions between a capture position and a release position. In the release position, the capture members can facilitate passage of the coupling heads through the guide openings. In the capture position, the first and second capture interface surfaces engage to mechanically interfere with passage of the coupling heads through the guide openings.

A soil collection attachment for movable equipment is described. The soil collection attachment includes a bucket including a bottom panel having an aperture, wherein the aperture is adapted to receive an excavation device such as an auger. A gate which is operated by a hydraulic cylinder is attached to the bottom panel. In a closed position, the gate covers the aperture to prevent excavation materials from falling through the aperture.

A dust suppression assembly is to be fixed on a handheld device. The dust suppression assembly comprises a device interface member having a top end and a bottom end and an intermediate member having a first intermediate end and a second intermediate end, the first intermediate end adapted to be coupled with the bottom end of the device interface member. Further, the device interface member is having a first channel and the intermediate member is having a second channel, the first channel and second channel joins to form a passage for supplying water to the working end of the tool for suppression of dust, while the handheld device is in use.

A spill container to be mounted below a rig floor. The spill container includes a collapsible concave container having an open top for catching fluid spilled on the rig floor, and a circular bottom opening adapted to receive a tubular member extending through the rig floor and downward below the concave container. The side walls of the concave container extend from the open top to the circular bottom opening. The open top of the concave container has a plurality of hangers extending there about to mount to the rig floor. An outer circumference of the open circular bottom opening has a plurality of hooks attached thereto for mounting to circular rings through which the tubular member extends outwardly therefrom.

A dust suction hood includes a tapered outer cover, a cylindrical outer cover, a tapered inner baffle plate disposed in the tapered outer cover, and a first blocking member matched with an opening in the other end of the cylindrical outer cover. A top opening of the tapered outer cover is matched with an opening in one end of the cylindrical outer cover. A side wall opening of the cylindrical outer cover serves as a dust outlet. A first gap is formed in the tapered outer cover. A first dust suction port formed between bottom openings of the tapered inner baffle plate and the tapered outer cover. A first drill pipe connecting port is formed in the first blocking member. A drill pipe of the mine drill passes through the first drill pipe connecting port to penetrate the dust suction hood on the drill pipe.

The invention relates to a drilling tool and a method for producing a bore in the ground, in which method ground material is carried away by a removal device on the underside of a main body of the drilling tool, flushing air is supplied by a feeding device into the bore, which is filled with drilling fluid, in the area of the removal device and ground material carried away by means of the flushing air is transported away through a discharge line. According to the invention, the ground material is transported to a receiving area in an upper section of the main body. A collecting hood is provided above the receiving area, which closes off the receiving area at the top, forming an air collecting space in which air collects. An outlet valve by means of which air is discharged from the air collecting space is arranged on the collecting hood.
