Abstract (en)
[origin: EP0903441A2] The arrangement is in the form of a transfer vibrator (13) with a transfer pipe (28). A hopper (27) with charging opening (30) is connected at the bottom area, to a vertical transfer pipe with a lower outlet (33). The vibrator mechanism (29) is housed in the bottom part of the pipe. Inside the pipe, a loosening rod (36) moves periodically in the lengthwise direction. The rod may extend from the hopper to the top end of the vibrator mechanism, and protruding transverse spikes (37) or hooks can be mounted on it. It can be actuated directly by a double-acting ram (35) or by a rotary crankshaft. Its bottom end can work in a lengthwise guide (38).
