Agricultural bagger with upper tunnel compaction

Abstract

An agricultural bagger apparatus and method for compacting feed into a horizontally deployed bag including a compression mechanism and an input hopper that receives agricultural feed. The hopper has a sloping wall and a lower end exit chute located to transfer the feed into the primary compression mechanism (e.g., a rotating toothed cylinder). The tapered hopper causes the feed to bridge, stopping the feed from falling through the chute. A new distribution mechanism in the hopper sweeps the feed adjacent to the sloping wall to prevent feed bridging. By preventing the feed from clogging, there is less reason to risk one's safety by foolishly inserting their limb into the hopper. Some embodiments also compact feed in the upper portion of the tunnel, for example, by reciprocating a hinged piston above the primary compression mechanism. This increases the compaction on the top portion of the tunnel without unduly juicing the feed.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This is a continuation of, and claims benefit of, U.S. patent application Ser. No. 09 / 977,036, Filing Date Oct. 11, 2001, now U.S. Pat. No. 7,024,839, issued Apr. 11, 2006, which is hereby incorporated by reference in its entirety.FIELD OF THE INVENTION [0002] This invention relates to the field of agricultural baggers, and more specifically to a method and apparatus of displacing pressure in the upper tunnel and for preventing bridging of feed in the input chute. BACKGROUND OF THE INVENTION [0003] Horizontally expandable, silage storage bags are commonly used as an alternative to permanent feed storage structures such as barns and silos. From an economic standpoint, an expandable plastic storage bag is preferable to a more elaborate, permanent structure. Further, the expandable bags are more easily loaded with feed than permanent structure and the silage stored therein is readily accessible for use, for example using a small tractor wi...

AI Technical Summary

Benefits of technology

Prevents feed bridging, enhances compaction throughout the bag, and reduces safety risks by maintaining feed flow without the need for manual intervention, resulting in a more efficient and safer bagging process.

Problems solved by technology

There are numerous problems that one contends with using previous bagging structures.

For example, there is a safety problem caused by feed that bridges within the tapered hopper.

Persons may be tempted to unclog the hopper by stomping or otherwise inserting an arm or a leg thus risking being sucked through and shredded by the primary compression mechanism.

Conventional baggers also suffer from an inability to adequately compact feed in the upper portion of the tunnel, thus leaving the feed in the lower bag highly compacted and the feed in the upper bag only moderately compacted.
