A self-propelled drilling head for drilling in soil by means of a multi-stage method comprises the drilling head having a housing and a drilling head tip arranged in the housing, and a spacer provided on the drilling head tip, by means of which the drilling head tip is in contact with the housing in order to change the multi-stage method to a method with a reduced number of stages.

Self-propelled drilling head

The invention relates to an earth drilling device () for boring a borehole into the soil and/or for drawing a line () into an underground passage, comprising at least one system line () extending from the earth drilling device to a start region, wherein the system line is designed in an electrically insulating manner.

Earth drilling device

An apparatus for mixing a powdery medium with a fluid includes a mixing vessel which can be filled with the fluid and which has a feed for the fluid, an inlet for the powdery medium and an outlet for the fluid mixed with the powdery medium, and at least one mixing screw arranged inside the mixing vessel and driven by a rotary drive.

Apparatus for mixing a powdery medium with a fluid

The application relates to a metering apparatus for introducing a powdery medium into a fluid, comprising a guide device for guiding the fluid and a metering device, said metering device being arranged above the guide device such that the powdery medium released by the metering unit is scattered onto the surface of the fluid.

Metering apparatus and method for introducing a powdery medium into a fluid

A metering apparatus for introducing a powdery medium into a fluid includes a mixing vessel that can be filled with a fluid and a metering unit for the powdery medium. The metering unit has an inlet for the powdery medium, an inlet for a compressed gas and an outlet extending towards the mixing vessel, through which the powdery medium and the compressed gas can be discharged into the mixing vessel.

An apparatus for mixing a powdery medium with a fluid includes a mixing vessel which can be filled with the fluid and which has a feed for the fluid, an inlet for the powdery medium and an outlet for the fluid mixed with the powdery medium, and at least one mixing screen which divides the mixing vessel into a first section which includes the feed and a second section which includes the inlet.
