The utility model provides a linear array automatic material conveying mechanism, include: the combination feed bin, the lower silo of arranging including a plurality of levels in proper order is provided with the photoelectric sensing ware that the one -to -one was put to a plurality of and unloading trench on the combination feed bin inside wall, give feed bin linear guide for two, the interval and etc. Highly set up on the opening of combination feed bin upper portion, slide for the feed bin and set up on two give feed bin linear guide, under the initial condition, feed position in storehouse in initial position treats that photoelectric sensing ware sensing does not have a material to the target unloading inslot that corresponds with it, then a drive motor drive driving motor drive assembly and then drive put the top for the feed bin to target unloading trench, feed hopper door opens and shuts cylinder drive feed hopper door and opens automatic blowing, during blowing volume that reaches the target, feed hopper door self -closing gets back to initial position for the feed bin voluntarily. The utility model provides a linear array automatic material conveying mechanism has improved the availability factor of giving the feed bin, and full -automatic unloading, uses manpower sparingly.
