  • Dry-bulk tanker, conveying system for a dry-bulk tanker, work train and method for conveying binding agents for a work train
    Patent number: 11326312
    Abstract: A dry-bulk tanker for the provision of binding agent for soil stabilization for a spreading device, comprising a storage container (10) for binding agent. An intermediate chamber (20) is connected to the storage container and is also connected to a compression chamber (40). A conveying device (22) for conveying of binding agent into the compression chamber (40) is arranged in the intermediate chamber (20). A conveying channel (44) is connected to the compression chamber (40). The conveying channel (44) can be connected to a spreading device (58). Furthermore, a pneumatic line (46) for feeding of conveying compressed air is connected to the compression chamber (40) and/or the conveying channel (44).

  • Dry-bulk tanker, conveying system for a dry-bulk tanker, as well as work train
    Patent number: 11098460
    Abstract: A dry-bulk tanker for the provision of binding agents for soil stabilization for a spreading device comprises a storage container (10) for binding agent. A mechanical conveying device (18) for conveying binding agents from the storage container (10) into an intermediate chamber (20) is connected to the storage container (10). A pneumatic conveying device (36) for conveying the binding agent to the spreading device is connected to the intermediate chamber (20). A pressure relief device (40, 41) is connected to the mechanical conveying device in order to avoid the entry of compressed air into the storage container (10). The invention furthermore relates to a conveying system for a dry-bulk tanker and to a work train for working soils with a self-propelled ground working machine and a dry-bulk tanker.
