Abstract
Abstract An auger hopper is usable with a screw flight auger to convey granular material, such as grain, from one depository station to another. The auger hopper has upwardly open bin means for temporarily holding the granular material as it is picked up by the auger. Adjustable inlet means are movably connected to the bin means and, in a normal configuration, releasably engage the bin means to close a front opening. The inlet means aids in guiding and deflecting granular material discharged from the first depository station to the hopper proper. Inlet means are movable inwardly to a position within the auger hopper proper to avoid damage as by collision when a truck is manipulated into discharge proximity of the hopper. Inlet means are movable outwardly of the auger hopper as to be out of the way when so desired.

An auger hopper having adjustable inlet means for temporarily holding of granular material being drawn and conveyed by an auger, said hopper including: upwardly open bin means; said bin means having a rear opening at one end for accommodation of a portion of said auger; said bin means having a front opening at the opposite end; said inlet means being mounted on the bin means to be movable between a first position outside the bin means, a second position closing the front opening of the bin means whereby granular material is deflected into the bin means, and a third position within the bin means; and fastening means to releasably fasten said inlet means in the second position closing the front opening of the bin means.
Claim 2
Dependent Claim
125 words
An auger hopper having adjustable inlet means for temporarily holding of granular material being drawn and conveyed by an auger, said hopper including: upwardly open bin means; said bin means having a rear opening at one end for accommodation of a portion of said auger; said bin means having a front opening at the opposite end; said inlet means being mounted on the bin means to be movable between a first position outside the bin means, a second position closing the front opening of the bin means whereby granular material is deflected into the bin means, and a third position within the bin means; and fastening means to releasably fasten said inlet means in the second position closing the front opening of the bin means.
Claim 3
Dependent Claim
88 words
The auger hopper of claim 1 wherein said inlet means includes: a front plate hingedly connected to the bin means; a pair of side plates hingedly connected to either side of the front plate; said side plates having a first portion of a fastening means; a second portion of fastening means disposed on the bin means; said first portion of fastening means engageable with said second portion of fastening means to releasably fasten the inlet means in the second position closing the front opening of the bin means.
Claim 4
Dependent Claim
