An adjustable chute structure is provided, which includes at least one chute and two cross beams disposed at two ends of the chute. Each end of the chute is connected with a chute plug, which is slidably mounted on the cross beams and is provided with a receiving groove. The receiving groove is provided with a movable switch, and a first mating member and a second mating member coupled with the movable switch. The cross beams are provided with a plurality of first limiting members arranged consecutively in a lengthwise direction, and the chute engages or plug-fits with the first limiting member through the first mating member to be fixed transversely between the cross beams. Each cross beam is provided with a second limiting member, and the chute is interlocked and connected with the second limiting member through the second mating member to be fixed longitudinally to the cross beams.

A debris chute assembly including a plurality of wall members selectively engaged with a scaffold. The plurality of wall members includes a passageway defined in a wall member of the plurality of wall members. A portion of the scaffold is received within the passageway. A flange is also provided on the wall member. The flange is removable securable to the scaffold. The wall member further includes a fastener provided thereon. The debris chute assembly may also include the scaffold which includes a plurality of standards and a plurality of ledgers. The plurality of standards are spaced a distance apart from one another. The plurality of ledgers extend between adjacent standards of the plurality of standards.

A debris chute assembly for removing debris from a height during construction or similar activity includes a scaffold, a plurality of wall members, and a plurality of corner members. The wall members hang on ledgers of the scaffold in tubular sections which align with each other. The corner members attach to standards of the scaffold and retain the wall members in fixed positions with respect to the scaffold. Various embodiments of corner members are provided which attach to the scaffold by various fastening means.

A concrete mix separating device for generating cement slurry from a concrete mix includes a bar, which is insertable between adjacent sections of a concrete chute so that a gap is created between the adjacent sections. The bar is sized so that aggregate of a concrete mix, which passes through the concrete chute, is selectively excluded from passing through the gap. Cement slurry, which is substantially free of aggregate, is generated from the concrete mix and passes through the gap. A funnel is attached to the bar so that the funnel is positioned below the gap upon insertion of the bar between the adjacent sections of the concrete chute. The funnel directs the cement slurry into a receptacle, such as a bucket or a wheelbarrow, which is positioned below the funnel.

The invention relates to a device for emptying a conveying bucket of rock/soil loosened during the sinking of a shaft with a chute (20) for the rock/soil (400) emptied from the conveying bucket (200, 200), which can be moved linearly between a conveying bucket transport position and a conveying bucket emptying position by means of an actuator. A receiving element (30) for the conveying bucket (200, 200) is provided for establishing a retaining connection between the chute (20) and the conveying bucket (200, 200), which is arranged on the chute (20) so as to be rotatable about an axis of rotation (33), the receiving element (30) being pivotable between a receiving position (420) and an emptying position (430) by means of an actuator (34).
