Abstract

An agricultural particulate feeder controls the rate of particulate distribution to a surface being worked. The particlate feeder comprises a hopper with a sliding door over a discharge outlet at a lower end of the hopper. A frame supports the particulate feeder and has an elongated tube extending longitudinally under the discharge outlet of the hopper, the tube forming an element of the frame. A particulate metering cylinder is positioned between the outlet and door of the hopper and a particulate inlet in the elongated tube and is rotatably mounted on a drive shaft. A housing encases the cylinder and forms an enclosure connecting the hopper outlet and the tube inlet. One side of the housing is removable to allow lateral access to the metering cylinder inside the housing. In addition, longitudinal removal of the drive shaft permits lateral removal of the metering cylinder from the housing. The frame is movably supported on the ground and has a mechanism to rotate the particulate metering cylinder and a fan to force air through the elongated tube to provide a fluid medium for transporting particulate away from the hopper.

Dependent claims

An agricultural implement adapted to be pulled longitudinally by a traction vehicle comprising a particulate feeder for controlling the rate of application of particulate to a surface being worked, the particulate feeder comprising;

a particulate hopper having a particulate discharge outlet at a lower end;
a sliding door over the discharge outlet, the sliding door being slidably variable in position to control the size of the particulate outlet;
a particulate metering cylinder rotatably mounted on a longitudinal axis under the sliding door;
means for rotating the metering cylinder;
a frame for supporting the particulate feeder, the frame having an elongated tube extending longitudinally under the hopper, and the tube having a particulate inlet aligned under the metering cylinder and discharge outlet;
a housing enclosing the metering cylinder and extending from the discharge outlet of the particulate hopper to the particulate inlet of the elongated tube to form an enclosure connecting the hopper discharge outlet and the tube particulate inlet;
said housing having a longitudinal side selectively removable from the housing for lateral access to the metering cylinder without interfering with metering cylinder rotation;
ground engaging means for movably supporting the frame;
and
air blower means for forcing air through the elongated tube to provide a fluid medium for transporting particulate away from the hopper and towards the surface being worked.
