Title: Material conveyor into collecting container - has compression and loading shovels guided downwards and rearwards on return stroke
Inventor: WENGER MANFRED
IPC: B65F3/20
Filed: 1974-09-19
Abstract: The conveyor is particularly for use in a refuse collector vehicle equipped with an intake hopper, a compression shovel separating the hopper from the main portion, and a loading shovel linked to the lower part of the compression shovel. Combined movement of the shovels delivers the rubbish from the hopper along a bottom wall into the main portion, and on the return stroke brings the loading shovel back above and clear of the loaded rubbish. To bring the loading shovel (16) back into the starting position (A1), both it and the compression shovel (15) work in guides. For a first part of their movement (S4') they move downwards together, and in a second part rearwards towards the lower edge (14A) of the intake hopper mouth. Thus the path followed by the shovels (S4) on the return stroke is convex in relation to the intake hopper mouth, leaving a correspondingly larger space into which the contents of a bin can be tipped.
