In an agricultural bag loading apparatus (10) having an output chamber tunnel (32), the improvement comprising a tunnel cleanout mechanism. The tunnel cleanout plate (82) is pivotally mounted on the output chamber tunnel (32) and is pivoted from a retracted position to an extended position by means of dual hydraulic cylinders (88). Compressed silage and material entrapped within the tunnel (32) is extracted by pivotal movement of the tunnel cleanout plate (82) from the retracted position, where the plate (82) does not interfere with the loading operation, to the extended position.

An agricultural bag loading apparatus having a tunnel cleanout mechanism comprising: an intake chamber; an output chamber tunnel having a bottomwall, sidewalls, a topwall and a backwall; a passageway connecting said intake chamber and said output chamber tunnel; a primary shaft rotatably mounted in said intake chamber and having teeth thereon for compressing said material and forcing said material from said intake chamber, through said passageway and into said output chamber tunnel; means mounted on said loading apparatus for stripping material from said teeth of said primary shaft, the interaction of said means and said primary shaft causing the material in said output chamber tunnel to be compressed and fed into an agricultural bag; means to rotate said primary shaft; means attaching the filled end of said agricultural bag to said loading apparatus, said means having a brake mechanism for yieldably permitting separation of the filled end of said agricultural bag and said loading apparatus in response to material being fed into said agricultural bag; a tunnel cleanout plate pivotally mounted at its top edge to the top wall of said output chamber tunnel, said plate being pivotable from a retracted position in which said plate abuts the inner surface of the topwall and backwall of said tunnel and the lower edge of the plate coincides with the upper edge of said stripping means with all edges of said plate abutting portions of the inner surface of said tunnel to avoid interference with the feeding of material into the agricultural bag, to an extended position, pivotal movement of said plate from the retracted to extended positions causing the lower edge of said plate to define an arcuate path extending toward the filled agricultural bag and downward with respect to the upper edge of said stripping means, the pivotal movement of said plate means from the retracted to extended positions removing substantially all of the material from said tunnel; hydraulic cylinder means having reciprocating piston means, the exposed end of the piston means pivotally mounted to the surface of said plate adjoining the inner surface of said tunnel said cylinder means pivotally mounted on said loading apparatus outside of said tunnel, said tunnel being slotted for passage of said cylinder means and the piston means therethrough.
