Abstract
A conveyor for particulate matter is provided with a channel extension movable between a use position aligned with the channel and a non-use position displaced relative to the channel. The extension includes an angled edge which cooperates with the auger flighting to shear material as it leaves the extension to break apart lumps which form in the material and provide an even flow of material from the conveyor.
Claims33
A device for dispensing particulate material comprising:
- a channel having a bottom axis, a terminal end wall, and a dispensing edge defined by the junction of said bottom and said end wall;
- and
- rotatable screw conveyor means in said channel for moving said particulate material axially toward said dispensing edge;
- wherein said dispensing edge is angled at an acute angle to said axis.
A device for dispensing particulate material comprising:
- a conveyor channel having an axis, a generally U-shaped contour transverse to said axis and a terminal end;
- auger means in said channel and having a helical flighting relative to said axis for moving said material along said channel toward said terminal end;
- and
- plate means at said terminal end, movable relative to said conveyor channel, providing a dispensing edge extending at an angle to said flighting for said flighting to move relative to said dispensing edge whereby said material is moved along said plate in a direction parallel to said axis and dispensed over said dispensing edge.
In a device for dispensing particulate material comprising a conveyor channel having an axis and a terminal end having a semicircular bottom, and rotatable screw conveyor means disposed in said channel for moving said particulate material in a direction of flow toward said terminal end, the improvement comprising:
- plate means mounted on said conveyor channel adjacent said terminal end for providing an axial extension of said channel, said plate means comprising a sheet portion, a terminal end wall and a dispensing edge defined by the junction of said sheet portion and said terminal end wall wherein said dispensing edge extends away from said terminal end at an acute angle to said axis.
In a device for dispensing particulate material comprising a conveyor channel having an axis and a terminal end having a semicircular bottom, and rotatable screw conveyor means disposed in said channel for moving said particulate material in a direction of flow toward said terminal end, the improvement comprising:
- plate means mounted on said conveyor channel adjacent said terminal end for providing an axial extension of said channel, said plate means including a dispensing edge extending away from said terminal end at an acute angle to said axis and having an axially inner edge, an axially outer edge parallel to said inner edge, a side edge parallel to and laterally spaced from said axis and extending between said inner and outer edges, and said dispensing edge extending between said inner and outer edges.
A method of evening the output of particulate material being dispensed from an end of a conveyor trough having a bottom and a terminal end wall and a dispensing edge defined by the junction of said bottom and said terminal end wall by a rotatable auger having an axis in said trough comprising the steps of:
- angling said dispensing edge at an acute angle to said axis and rotating said auger relative to said dispensing edge for said auger to move material in a direction parallel to said axis and toward said dispensing edge.
A device for dispensing particulate material comprising:
- trough means;
- means providing said trough means with end edge means;
- auger means having flight means for moving said material along said trough in a flow direction toward said end edge means;
- said flight means extending across said end edge means;
- and
- said means providing said trough means with end edge means having a first position relative to said trough means wherein said end edge means is an edge normal to said flow direction and a second position wherein said end edge means is an edge extending at an acute angle with respect to said flow direction.
