Abstract
Apparatus for creating a path through particulate material such as granular or pulverulent material in a storage container is lowerable into the material in the container and includes an upper part attachable to a lowering device and a lower part. The lower part has a downwardly and inwardly inclined outer wall extending to a lower central area, a vibrator for vibrating the outer wall along a substantially vertical axis, and an air nozzle at the lower central area to which air can be supplied.

Apparatus for creating a path through particulate material such as granular or pulverulent material in a storage container, said apparatus being lowerable into the material in the container and comprising an upper part attachable to a lowering device and a lower part, the lower part having a downwardly and inwardly inclined outer wall extending to a lower central area, vibrator means for vibrating said outer wall along a substantially vertical axis, when the apparatus is suspended from the lowering device, air nozzle means at the lower central area, and means for supplying air to said air nozzle means.
A method of creating a path through particulate material such as granular or pulverulent material in a storage container, including lowering into the material apparatus comprising a lower part having a downwardly and inwardly inclined outer wall extending to a lower central area, vibrator means for vibrating said outer wall along a substantially vertical axis, and air nozzle means at the lower central area, supplying air to the nozzle means to cause air to be emitted from the nozzle means and displace relatively loose material, and operating the vibrator means to cause vertical vibration of the outer wall to displace material causing blocking.
