Adjustable pneumatic density control means for an agricultural bagging machine

Abstract

An adjustable pneumatic density control is provided for an agricultural bagging machine which not only acts as an anchor against premature movement of the machine as the bag is being filled, but also controls the density of the material being packed in an agricultural bag. The adjustable pneumatic density control comprises an inflatable bladder which is supported upon the rearward end of a flexible cable extending from the frame of the bagging machine. An air line extends to the bladder to supply air to the interior thereof to enable the size of the bladder to be selectively varied. A density control gauge or meter is imposed in the air line to enable the operator to ascertain and control the pressure within the bladder. An optional shield is also provided which extends partially around the bladder to reduce wear on the bladder and to prevent damage to the bladder.

I claim:  
     
         1 . The method of controlling the density of material being bagged within a bag by a bagging machine, comprising the steps of: 
 positioning an inflatable bladder-like material engaging member within the material being bagged;    and selectively varying the size thereof to selectively vary the density of the material being bagged within the bag.    
     
     
         2 . The method of  claim 1  wherein the material engaging member is deflated prior to the removal thereof from the bag after the material has been bagged.
