Abstract
A spreader for solid manure and other particulate material includes upright rotational beaters having paddles to dispense product from the rear of a wagon onto an agricultural field. The paddles on the beaters overlap along a midpoint between the beaters to improve product distribution on the field. The perimeter edges of the paddles are in close proximity to the side edges of the beater frame to facilitate product sheer, and thus improved distribution. The paddles on each beater are vertically and radially offset, and at least some of the paddles are spring-loaded.
Claims19
A solid manure spreader, comprising:
- a wagon for holding solid manure;
- a conveyor extending from front to back in the wagon to carry the solid manure to a rear end of the wagon;
- a pair of beaters rotatably mounted at the rear end of the wagon, the beaters being forwardly inclined from bottom to top and being adapted to rotate in opposite directions from one another;
- the beaters having a plurality of spring-loaded pivotal arms, each arm having inner and outer ends and a pivot axis between the inner and outer ends;
- springs each having a fixed first end and a second end connected to the inner end of one of the arms to bias the inner and outer ends of the one arm in a same direction of rotation as a direction of rotation of the beater;
- and
- each arm having a paddle removably and rigidly fixed to the outer end to dispense the manure from the rear end of the wagon onto a field.
A material spreader to dispense particulate material onto a field, comprising:
- a wagon for holding the material;
- a conveyor extending from front to back in the wagon to carry the material to a rear end of the wagon;
- a pair of beaters rotatably mounted at the rear end of the wagon;
- the beaters having a plurality of pivotal arms, and each arm having an inner end and an outer end, and a pivot axis between the inner and outer ends;
- a paddle on the outer end of each arm to dispense the material from the wagon when the conveyor is actuated and the beaters rotate;
- and
- a spring on the inner end of each arm to bias an outer end of the arm toward a direction of rotation of the arm.
A manure spreader for distributing manure onto a field, comprising:
- a wagon for holding manure;
- a conveyor to move the manure toward a rear end of the wagon;
- a pair of upright beaters at the rear end of the wagon;
- each beater having:
- an upright rotatable shaft, a plurality of vertically spaced plates fixed on the shaft, a plurality of arms pivotally mounted on the plates so as to extend outwardly beyond the plates and to rotate with the shaft in a first direction, and having a paddle, wherein each arm has an inner end fixed to one of the plates and an outer end, with a pivot axis between the inner and outer ends;
- and a plurality of springs each having a fixed first end and a second end connected to the inner end of one of the arms so as to urge the one arm in the first direction.
