Abstract
Abstract The feed-material-handling apparatus has a frame vertically supporting a feed material blower with an upwardly extending transition discharge member and horizontally supporting an impeller with a rotor for delivering feed material to the blower. The blower discharges the material upwardly through the transition member. In the two forms of the horizontal impeller the rotor turns clockwise in one and counterclockwise in the other. The frame is mounted on detachable wheels.

A feed-material-handling apparatus comprising: a frame with a beam extending generally perpendicular therefrom; a vertical blower vertically mounted on said frame and having a vertical side with means for introducing feed material in the side thereof, means for upwardly discharging feed material from said blower and a fan with a shaft rotatably supported in said blower for propelling feed material through said upward discharge means; a horizontal feed impeller means mounted on said beam and having a generally horizontal casing with a bottom and upwardly extending sidewall and a generally horizontal rotor rotatably mounted in said casing to turn about a vertical axis; a trough-shape transfer means connecting said horizontal feed material impeller means and said vertical blower for delivering feed material to said blower propelled by said rotor; and said horizontal feed impeller means has a rotor plate spaced from said sidewall by a substantial distance and has a plurality of blades with said blades having outer edges adjacent said sidewall and having inner end a short distance from the periphery of said rotor plate to provide a substantially clear area on top of said rotor plate.
Claim 2
Dependent Claim
188 words
A feed-material-handling apparatus comprising: a frame with a beam extending generally perpendicular therefrom; a vertical blower vertically mounted on said frame and having a vertical side with means for introducing feed material in the side thereof, means for upwardly discharging feed material from said blower and a fan with a shaft rotatably supported in said blower for propelling feed material through said upward discharge means; a horizontal feed impeller means mounted on said beam and having a generally horizontal casing with a bottom and upwardly extending sidewall and a generally horizontal rotor rotatably mounted in said casing to turn about a vertical axis; a trough-shape transfer means connecting said horizontal feed material impeller means and said vertical blower for delivering feed material to said blower propelled by said rotor; and said horizontal feed impeller means has a rotor plate spaced from said sidewall by a substantial distance and has a plurality of blades with said blades having outer edges adjacent said sidewall and having inner end a short distance from the periphery of said rotor plate to provide a substantially clear area on top of said rotor plate.
Claim 3
Dependent Claim
26 words
A feed-material-handling apparatus as set forth in claim 1, wherein said blades have a generally Z-shaped cross section with a horizontal portion and downwardly extending portions.
Claim 4
Dependent Claim
30 words
A feed material handling apparatus as set forth in claim 1, wherein said sidewall is cylindrical in shape with its main axis coinciding with the vertical axis of said rotor.
Claim 5
Dependent Claim
38 words
A feed-material-handling apparatus as set forth in claim 1, wherein said frame comprises two spaced parallel upright panels on opposite sides of said vertical blower and having upwardly extending supports attached to opposite sides of said vertical blower.
Claim 6
Dependent Claim
50 words
A feed-material-handling apparatus as set forth in claim 4, wherein said upright panels have long base portions, respectively, extending in parallel spaced relation along the bottom of the apparatus and extending upwardly to adjacent said fan shaft and having top portions with bearing means for rotatably supporting said fan shaft.
Claim 7
Dependent Claim
85 words
A feed material handling apparatus as set forth in claim 1, wherein rotatable shaft means and a belt and pulley drive are provided, said shaft means are rotatably mounted in said beam and drivingly coupled to said rotor and extending adjacent to said upright panel and said belt and pulley drive comprises two pulleys mounted on said fan shaft and said shaft means, respectively, and a belt connecting said fan shaft to said shaft means for driving said horizontal rotor on operation of said blower.
Claim 8
Dependent Claim
36 words
A feed-material-handling apparatus as set forth in claim 6, wherein a power takeoff shaft is provided and is connected to said fan shaft on the opposite side of said blower from said horizontal feed impeller means.
Claim 9
Dependent Claim
101 words
A feed-material-handling apparatus as set forth in claim 7, wherein said belt is loosely mounted on said pulleys for assuming a nondriving relation and said belt and pulley drive includes an idler pulley, an arm pivotally mounted on said frame and rotatably supporting said idler pulley to move in and out of engagement with said belt to press said belt into a driVing relation with said pulleys, link means connected to said arm and said lever having two links passing dead center and pressing said idler pulley against said belt to hold said belt in a driving relation with said pulleys.
Claim 10
Dependent Claim
33 words
A feed-material-handling apparatus as set forth in claim 8, comprises a lever extending perpendicular to said frame and pivotal about an axis perpendicular to said frame and connected to one of said links.
Claim 11
Dependent Claim
52 words
A feed-material-handling apparatus as set forth in claim 9, wherein said linkage means is moved to the dead center position by movement of said lever towards the side of said apparatus so that movement towards said apparatus swings the idler pulley off said belt to disconnect said rotor from said fan shaft.
Claim 12
Dependent Claim
26 words
