Agricultural bag loading apparatus braking mechanism

An improved brake mechanism for deploying the attachment means between the filled end of an agricultural bag and an agricultural bag loading apparatus in response to the loading of material into said agricultural bag, said improvement comprising:

• a plurality of drum means rotatably mounted on said loading apparatus and having said attachment means secured thereto, said drum means deploying said attachment means and lengthening the separation between the filled end of said agricultural bag and said loading apparatus upon rotation of said drum means in one direction, said drum means storing excess attachment means;
• a disc brake rotor forming one end of at least one of said drum means;
• a plurality of disc brake calipers attached to said loading apparatus, said calipers surrounding said disc brake rotor so that the pistons within said calipers will bear against said disc brake rotor to resist motion between said calipers and said disc brake rotor;
• and
• a variable pressure fluid pressurizer for pressurizing a fluid within said calipers and urging said pistons into contact with said disc brake rotor.

An improved brake mechanism for an agricultural bag loading apparatus for loading silage and the like into an agricultural bag, said loading apparatus including an intake for receiving silage, an output for discharging silage into an agricultural bag, and a silage moving device for forcing silage from the intake into the output and into the agricultural bag, said brake mechanism maintaining a desired tension in a cable means connecting the filled end of said agricultural bag and said loading apparatus during the filling operation, said improvement comprising:

• a plurality of cable drum means mounted for rotation on a common connecting shaft means on said loading apparatus, said drum means having said cable means secured thereto and deploying said cable means and lengthening the separation between the filled end of said agricultural bag and said loading apparatus upon rotation of said drum means in one direction, said drum means storing excess cable means during operation of said loading apparatus;
• a disc brake rotor secured to one end of one of said cable drum means, said rotor forming a raised edge formed radially outwardly from the outer surface of said drum mean, said edge containing said cable means on said drum means;
• a plurality of disc brake calipers rigidly mounted on said loading apparatus and having a plurality of pistons moveably mounted in the body of said calipers, said pistons being situated for urging against the outer surface of said disc brake rotor to resist relative rotation between said calipers and said rotor;
• and
• a variable pressure fluid pressurizer urging said pistons into contact with said rotor.
