Abstract

An apparatus and method for removing water hyacinths. The system of the present invention utilizes a transfer mechanism and grapple to collect hyacinth material from a body of water. The collected material is then passed to a transport for delivery to a header unit and grapple. The header unit grapple then retrieves the hyacinth material and delivers it to a collection bin for processing. The chopped hyacinth material is thereafter discharged for subsequent use as a biomass.

Claims

1. A system for chopping water plant material comprising:

a header unit forming a collection bin having an inlet for receiving unprocessed water plant material and an outlet, a conveyance positioned within the collection bin, the conveyance being used to simultaneously transport the water plant material towards the outlet of the collection bin and process the water plant material into a form suitable for subsequent disintegration;

a forage chopper with feed rollers and cutting knives, the feed rollers delivering the water plant material from the outlet of the collection bin into the cutting knives, the cutting knives disintegrating the water plant material.

2. A method of disintegrating collected water plant materials comprising the following steps:

delivering the collected water plant materials into a container with an outlet, providing a conveyance within the container;

processing the collected water plant materials by way of the conveyance into a form suitable for subsequent disintegration;

transporting the collected water plant materials concurrently with the processing by way of the conveyance to the outlet of the container;

forcing the collected water plant material from the outlet of the container and into a series of cutting knives;

disintegrating the plant material via the cutting knives.

3. The method as set forth in claim 2 including the further step of gathering the water plant material prior to delivery into the container.

4. The method as set forth in claim 2 wherein the collected water plant materials are delivered into the container by way of a grapple mechanism.

5. The method as set forth in claim 2 wherein the collected water plant materials are processed by way of an auger.

6. The system as set forth in claim 2 wherein the collected water plant material are delivered into the header by a conveyor.

8. The system as described in claim 6 wherein the conveyance also processes the collected material into a form suitable for disintegration.

9. The system as described in claim 6 wherein the conveyance is an auger.

7. A system for disintegrating collected water plant materials comprising:

a header unit including a collection bin and conveyance, the conveyance being employed in transporting collected water plant materials through the collection bin, the collecting bin also including means for processing the collected water plant materials into a form suitable for subsequent disintegration;

a chopper interconnected to header unit and adapted to receive processed collected water plant materials therefrom, the chopper functioning to disintegrate the previously processed water plant materials.
