Feed control for tub type hay grinder

In combination with a forage grinder having a hopper with a stationary wall, and a grinding cylinder having grinding means protruding through a provided opening in said stationary wall into said hopper, and feed means for moving forage material to be ground along said wall and across a forage input side of said grinding means, the improvement comprising an adjustable forage feed control member capable of deflecting forage material moved thereover mounted in relation to said wall adjacent to said cylinder and on the forage input side of said cylinder, and track means to guide said feed control member between at least two positions wherein said feed control member permits different amounts of material in said hopper being moved toward said cylinder by said feed means to come into contact with said grinding means protruding into said hopper as the forage material passes thereover, said track means to guide said feed control member guiding movement of said feed control member from a position where said feed control member does not substantially protrude into said hopper beyond said stationary wall member to a second position wherein said feed control member protrudes beyond said wall member into said hopper a distance substantially equal to the amount of protrusion into said hopper of said grinding means.

In combination with a forage grinder having a hopper with a floor, and a grinding cylinder having grinding means protruding through a provided opening in said floor into said hopper, and feed means for moving forage material to be ground along said wall and across a forage input side of said grinding means, comprising a rotating tub wall mounted in said hopper for rotation about a substantially vertical axis, the improvement comprising an adjustable plate member mounted in relation to said wall adjacent to said cylinder and on the forage input side of said cylinder, and means to permit movement of said plate member between at least two positions wherein said plate member permits different amounts of material in said hopper being moved toward said cylinder by said feed means to come into contact with said grinding means protruding into said hopper as the forage material passes thereover.

A feed adjustment device for a forage grinder having a hopper with a stationary flow, a rotary grinding cylinder having grinding means protruding into the hopper through a provided opening in said floor, feed means for moving the forage material to be ground along said floor and across said grinding means, said feed adjustment device comprising an adjustable plate member having an edge generally parallel to the axis of rotation of said grinding means and positioned to the side of said cylinder toward the forage material being moved into the cylinder by said feed means, means to mount said adjustable plate member in relation to said floor with the edge adjacent said cylinder, and for movement from a first position wherein the adjustable plate member does not substantially interfere with movement of forage material across the grinding means to a second position wherein the adjustable plate member projects outwardly from said floor to shield the adjacent side of said cylinder from forage material moved by said feed means, and means to adjustably secure said adjustable plate member in selected locations along said means to mount.
