Abstract: The invention relates to a device for sinking a vertical borehole, more particularly a shaft, an extraction borehole in a deposit body, or a foundation borehole in the ground, with at least one excavating tool for excavating material from the bottom of the borehole, with an at least one conveyance means arranged in the active region of the at least one excavating tool for conveying away from the borehole material excavated from the bottom, with a machine frame on which at least two bracing elements are arranged for locking the device in the borehole during boring, with at least one means for vertically raising and lowering the boring device in the borehole and with at least one drive for rotating the excavation tool.

Abstract: 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).

Abstract: A drill head and a method having a body connected to a rotary drive of a drilling device, for loosening the ground at a face of the borehole, having a discharge device for discharging the loosened ground to a suction unit for suctioning a conveying medium, wherein the discharge device has at least one opening in the region of the drilling tools The at least one opening is connected to a suction box which has, at an end opposite the opening a connector opening for connecting to a conveying line, that acceleration exerted on the loosened ground in the region of the suction box moves loosened ground through the opening into the suction box wherein the loosened ground acquired by the conveying medium in the opening and/or in the suction box and is discharged.

Abstract: The invention relates to a drill head and to a method for producing a substantially vertical borehole in the ground, in particular for producing a shaft, having a body (11) which is able to be connected to a rotary drive of a drilling device, having drilling tools (12) which for loosening the ground at a face (100) of the borehole are disposed on the body (11), having a discharge device which for discharging the loosened ground on the face (100) is able to be connected to a suction unit for suctioning a conveying medium (90) by way of a conveying line (31), wherein the discharge device has an opening region (22) which is disposed on the body (11) and has at least one opening (23) in the region of the drilling tools (12) at the face.
