Abstract
PURPOSE: To extend soil conveying distance by arranging such accelerators in a conveyor pipe at predetermined intervals as to release the conveying pressure fed from the upstream side into the atmosphere and to refeed compressed air for downstream conveyance.
CONSTITUTION: In a device comprising a pressure feeder 1 arranged at the base end of a conveyor pipe 2 for conveying soil plugs 8 through the pipe 2, accelerators 3 are arranged in the pipe 2 at predetermined intervals Lo so determined as to enable the conveyance of maximum feed amount in minimum cycle time. When the soil plug 8 has been decelerated or stopped on passing by a release port 4, the pressure change is detected by a presure switch 5 and a first valve 7 is closed. Then, with a second valve 10 opened, the compressed air flowed through a conveyance pressure nozzle 9 is changed over to an acceleration compressed-air nozzle 6. The same cycle is repeated to convey the soil plug 8.
