Abstract:
A baler for sequenced baling operation of materials such as waste cardboard, the baler comprising:a. an upper hopper segment for receiving uncompacted material to be baled; b. a lower hopper segment, beneath the upper hopper segment, said lower hopper segment for receiving material to be baled from the upper hopper segment; c. a pre-crush chamber beneath the lower hopper segment; d. a pre-compression lid pivotally secured with respect to the lower hopper segment to rotate through the lower hopper segment so as to force material to be baled from within the lower hopper segment into the pre-crush chamber, said pre-compression lid being oriented to function as a top for the pre-crush chamber in a closed position and to allow material to be baled to enter the pre-crush chamber in an open; e. a hydraulic cylinder actuator coupled to the pre-compression lid for moving the pre-compression lid between the open and closed positions; f. at least one pre-compression lid stop mounted on the pre-compression lid and movable therewith; and, g. an angled fixed stop against which the at least one pre-compression lid stop bears when the pre-compression lid is in the closed position, whereby movement of the pre-compression lid into the pre-crush chamber is prevented; and, h. wherein the at least one pre-compression lid stop is adjustable and includes a shim and at least one mounting bracket having a curved edge.
