| 摘要 |
The present invention relates to a conveyor apparatus (1) having a moving floor and comprising at least two alternate sets (7, 8) of parallel bars (2, 2a, 2b) on which rests the charge (6) to be transported, said conveyor apparatus being characterized in that, on the one hand rigid connection (9, 11) and support (15, 16) means connect the sets (7, 8) of bars (2, 2a, 2b) to two different excentric mecansisms (10, 12, 21), with a fixed distance between the axes, rotating normally in contrarotary directions about their respective rotation center (10a, 12a) at preferably similar frequencies so that said sets (7, 8) are alternatingly driven with respective feed and return motions at distinct high and low levels, and in that, on the other hand, said support means (15, 16) are upwardly biased by springs (17, 18) baring on the frame (3) of the conveyor apparatus (1) and alternatingly bringing the support means (15, 16) corresponding to be upper set (7, 8) of bars (2, 2a, 2b) in positive abutment against fixed reverse bearings (19, 20) at a constant level. |
