DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The invention relates to feeders for distributing feed to livestock. The feeder is mounted above an elongated livestock feed bunk.
In operation, feed is more or less equally dropped from the feeder along the length of the feed bunk or at least a portion of the length of the feed bunk.
Livestock line up on either one or both sides of the feed bunk and get substantially equal portions of the feed from the feeder.
BACKGROUND ART
Tapered bed feeders are well-known in the art. These feeders, with continuous chain and slat conveyors that convey feed along the upper surface of a bed which decreases in width so that feed falls off, have been used comercially for many years. The sides of these feeders, which form the frame, support the tapered bed and provide support for the upper and lower runs of the conveyor chain, are normally constructed from formed sheet metal with angles, channel and other pieces welded or bolted to the sheet metal. Due to the complexity of the construction, sections of these feeders are normally constructed in a factory. The relatively bulky sections are shipped to the farm where they are to be used. The sections are joined end to end above the feed bunk to form a feeder of the desired length.
DISCLOSURE OF INVENTION
The tapered bed feeder conveyor includes a center section; a tapered bed secured to the center section; an idler shaft support, idler shaft and a conveyor sprocket attached to one end of the center section; a drive shaft support, drive shaft and conveyor drive sprocket secured to the other end of the center section; and at least one endless chain trained around the sprockets on the idler shaft and drive shaft with conveyor slats extending from the endless chain. The idler shaft support is fabricated by welding and bolting various metal parts into a single assembly. The drive shaft support is also fabricated by welding and bolting various metal parts into a single assembly. The elongated center section includes at least two reversible and identical side panel members formed from sheet metal with integral tapered bed support ledges and endless chain return support ledges. The side panel members can be nested together for compact storage and shipment. Spacer bracket assemblies are used to connect panel members together in a parallel spaced apart relationship. The spacer bracket assemblies also connect side panel members together in end to end relationship to provide the desired overall length feeder.
The side panel members also include a flange for securing a cover on the feeder without the use of fasteners.
A cover is provided that has lips engageable with the conveyor cover retaining flanges.
Antifriction material is secured to the conveyor slats to reduce friction, wear, and noise and to increase the life of the feeder.
The tapered bed support ledge on each side panel is below the integral endless chain return support ledge.
A center section of the tapered bed feeder includes at least one spacer bracket assembly. The spacer bracket assembly has generally vertical side sections. Two side panel members are secured to each side section of the spacer bracket assembly in an end to end relationship.
