Abstract

An agricultural implement especially designed to distribute liquid, semi-liquid and solid forms of manure to a field. The manure spreader includes a V-shaped tank and two troughs below the tank. Each trough has an auger disposed in it. Wiper bars are provided to prevent build up of manure on the auger blades. An internal beater breaks up any manure that has bridged over the augers. An external beater, spaced apart from the rear of the tank is adapted to distribute the various forms of manure. A receiver conveys the manure from the troughs to the external beater.

Claims

1. An agricultural implement for transporting and spreading manure, having a tank for holding the manure, the tank having a discharge end, an opposed end, a pair of inwardly and downwardly sloped sidewalls therebetween, and a lowermost conveyor trough, comprising;

auger means rotatably carried within the conveyor trough for directing manure through the conveyor trough towards the tank discharge end, the auger means including a first auger member having a first auger member rotatable longitudinal shaft and a generally spiral first auger member blade for rotation therewith including a first auger member inner blade edge operably coupled to the first auger member shaft and a first auger member outer blade edge presenting a first auger member outer circumference;

wiper means comprising a first elongated wiper bar extending generally parallel to said first auger member longitudinal shaft; and

wiper mounting means for adjustably mounting the wiper bar adjacent the auger means in operable, adjustable wiping engagement with the first auger member spiral blade, whereby said wiper bar can be adjustably, laterally shifted into wiping engagement with said first auger member outer blade edge for regulating the buildup of manure on the first auger member as it rotates in the conveyor trough.

2. The invention as claimed in claim 1, including retainer means adapted for keeping said auger means in operable wiping engagement with said wiper means, said retainer means comprising a first elongated bar extending generally parallel to said first auger member longitudinal shaft, said first elongated bar operably disposed with respect to said first auger member to resist the tendency of said first auger member to ride up and out of the conveyor trough when said first auger member is in rotation.

3. The invention as claimed in claim 1, said first auger member spiral blade including a plurality of flightings, said first elongated bar extending across at least two of said flightings.

4. The invention as claimed in claim 1, said auger means including a second auger member oriented generally parallel to said first auger member in generally side to side relationship therewith, said second auger member including a second auger member rotatable longitudinal shaft and a generally spiral second auger member blade for rotation therewith including a second auger member inner blade edge operably coupled to the second auger member shaft and a second auger member outer blade edge presenting a second auger member outer circumference, said wiper means comprising a second elongated bar extending generally parallel to said second auger member longitudinal shaft, said wiper mounting means including means for mounting said second elongated bar in operable wiping engagement with the second auger member outer blade edge.

5. The invention as claimed in claim 4, said second auger member spiral blade including a plurality of flightings, said second elongated bar extending across at least two of said flightings.

6. The invention as claimed in claim 4, said mounting means including means for laterally adjusting said first and second elongated bars into wiping engagement with said first and second auger members respectively.

7. The invention as claimed in claim 4, including retainer means adapted for keeping said auger means in operable wiping engagement with said wiper means, said retainer means including a first elongated bar extending generally parallel to said first auger member longitudinal shaft and a second elongated bar extending generally parallel to said second auger member longitudinal shaft, said first elongated bar operably disposed with respect to said first auger member and said second elongated bar operably disposed with respect to said second auger member to resist the tendency of said first auger member and said second auger member to ride up and out of the conveyor trough when said first auger member and said second auger member are in rotation.

8. The invention as claimed in claim 1, including internal beater means operably rotatably carried by the sidewalls of the tank transverse to the first auger member longitudinal shaft for agitating manure within the tank and moving the manure inwardly and downwardly in the tank.

9. An agricultural implement for transporting and spreading manure over a field, comprising;

a manure receiving tank having a front wall, an opposed rear wall and a pair of inwardly and downwardly sloped sidewalls extending between said front wall and said rear wall, and a tank bottom wall extending between said sloped sidewalls to present a tank bottom width extending between said sloped sidewalls;

a pair of augers rotatably carried within the tank adapted for directing manure towards the tank rear wall, said pair of augers being aligned generally side by side along said tank bottom wall to present a combined auger width extending generally across said tank bottom width;

gate means operably carried by said rear wall for selectively releasing said manure from said tank, said gate means presenting a spreader discharge width, said spreader discharge width being at least as wide as said combined auger width;

an external beater oriented rearwardly of and spaced apart from said rear wall, said beater having a generally horizontally disposed beater longitudinal axis oriented generally orthogonal to said pair of augers and flighting elements extending along said longitudinal axis adapted for spreading said manure over said field in a swath having a width wider than said spreader discharge width; and

receiver means extending generally between said gate means and said external beater for conveying manure from said gate means into spreading engagement with said external beater.

10. The invention as claimed in claim 9, said receiver means including a moveable member selectively shiftable between a closed position wherein said receiver means provides a generally continuous path for said manure between said gate means and said external beater and an open position wherein said receiver means presents a gap between said gate means and said external beater wherein manure discharged through said gate means is expelled from said receiver means clearing said external beater.

11. The invention as claimed in claim 9, including an internal beater operably rotatably carried by the sidewalls of the tank transverse to the augers for agitating manure within the tank and moving the manure inwardly and downwardly in the tank.
