Abstract

A machine arranged to insert material to be composted into an elongate elastic bag. The machine is arranged to insert an elongate perforated pipe into the elongate elastic bag with the material. The perforated pipe is fed from an air tight container through a conduit into the bag. The machine may have an expander mechanism to enlarge the opening of the elastic bag with the expanding mechanism defining a tunnel through which the material will be forced into the bag. A reciprocating plunger movable within a channel or hopper forces the material into the elongate bag. The machine is arranged so that the composting process may commence when there is material available to only partially fill the bag. When a bag is filled partially, the plunger is moved to a position at the entry of the tunnel to seal the open end of the bag and a media may be applied to dispense the media into the material via the perforated pipe to commence the composting process. The operation of the machine may be controlled remotely such as by a transmitter. Power for operating the mechanism of the machine may be provided by a motor mounted on the machine or from a tractor.

Claims

1. A system for bagging large quantities of loose material such as grain and materials to be composted whereby a large bag containing such material is filled at and stored in the field, said system comprising:

a mobile bagging machine including a tunnel having an opening there through and a forward and rearward end, a materials holding channel permanently mounted to and extending forwardly of the tunnel, said channel having an open top receiving sequential loads of loose material to be bagged, and a piston having a solid rear face sized ad configured to closely fit the channel and the forward end of said tunnel, said piston mounted for reciprocating movement between a retracted position forward of the material deposited in the channel and through the channel into the forward end of the tunnel for movement of the material from the channel into the tunnel;

a bag having an end opening and mounted on and surrounding the rearward end of the tunnel and closing the rear opening, said bag provided on said tunnel in a folded condition and upon receiving the material forced through the tunnel and into the bag by the piston, said machine being advanced as the bag is filled, the bag accordingly being deployed off the tunnel;

said tunnel, channel, piston and bag functioning as an integral on site unit and it cooperation with hauling units hauling multiple loads of the material to the site, said channel sequentially receiving said multiple loads and said reciprocating piston in a plurality of reciprocating movements, sequentially moving said loads through the channel and tunnel for deposit into said bag;

controls controlling said sequential movement of the piston and for selectively positioning the piston in the tunnel entry as desired for holding the material in the bag between loads;

a conduit extended from the exterior of the machine into and through the tunnel and into the bag, and a length of pipe mounted on the machine for feeding of the pipe through the conduit and into the material being bagged; and

said conduit connectable to a media source with said piston closing the tunnel front and opening with the bag in a partially filled condition for circulating media from the media source into the material in the bag between loads.

2. A system as defined in claim 1 wherein the bags are elastic and in a relaxed state have a smaller end opening than the tunnel, said tunnel being collapsible and a motor member for collapsing and expanding the tunnel whereby the tunnel is collapsed for mounting the bag to the tunnel and expanded to thereby stretch the bag opening.

3. A system as defined in claim 1 wherein said pipe is perforated and including an air tight receptacle mounted to the machine, said length of pipe in coiled form contained in the receptacle with an end thereof fed directly into the feed conduit and from the conduit into the bagged material, and an air pressure source connectable to the receptacle for pressurizing the receptacle and thereby forcing air into and through the perforated pipe and into the bagged material.

4. A system as defined in claim 1 wherein a motor mounted on the machine provides power for reciprocal movement of the piston.

5. A system as defined in claim 1 wherein the channel is provided as a hopper having an open top for receiving loose material, a cover provided on said piston and extended forwardly of the piston, said cover being moved into the hopper as the piston is moved toward the tunnel, said cover configured to close the hopper over the piston with the piston positioned at the forward position in the forward opening of the tunnel.

6. A system as defined in claim 3 wherein the channel is provided as a hopper having an open top for receiving loose material, said loose material being refuse for composting, whereby said bag can be partially filled and with the piston positioned in the tunnel opening, the refuse material in the bag can be treated for composting.

7. A system as defined in claim 3 wherein the conduit extends from a position forward of the channel and extends through the channel and through an opening in the piston and into the tunnel, said piston being slidable relative to the conduit.
