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.

Dependent claims

A bagging machine for bagging material into bags having a closed end and an open mouth, comprising:

a wheeled frame having rearward and forward ends;
a tunnel on said wheeled frame having an intake end for receiving the material to be bagged and an output end adapted to receive the open mouth of the bag;
said tunnel having opposite sides;
a material receiving means on said wheeled frame forwardly of said tunnel for receiving the material to be bagged;
a material packing means on said wheeled frame at the intake end of said tunnel for forcing the material to be bagged from said material receiving means into said tunnel and into said bag;
and a density control assembly positioned rearwardly of the intake end of said tunnel;
said density control assembly comprising a support which is operatively secured to said frame means and an inflatable bladder-like material engaging member supported by said support so that said bladder-like material engaging member is in engagement with the material being bagged to resist the movement of said bagging machine away from the bagged material, thereby controlling the density of the bagged material.
