Abstract
An agricultural vehicle includes a chassis, wheels supporting the chassis for moving the vehicle, an application system supported by the chassis and including a product tank storing a volume of agricultural product for delivery onto an agricultural field, and an application boom configured to deliver the agricultural product to the agricultural field. The application boom includes a composite tube, and a sleeve surrounding the composite tube to support the composite tube at a stress point of the composite tube.
Claims14
An agricultural vehicle comprising:
- a chassis,
- wheels supporting the chassis for moving the agricultural vehicle;
- an application system supported by the chassis and including a product tank storing a volume of agricultural product for delivery onto an agricultural field;
- an application boom configured to deliver the agricultural product to the agricultural field, the application boom including:
- a boom center section;
- a boom arm pivotably coupled to the boom center section, the boom arm including a composite tube having an end;
- a non-composite member coupled with the composite tube at the end of the composite tube;
- and
- a ferrule surrounding the end of the composite tube and fastening the non-composite member to the composite tube;
- wherein the non-composite member couples the boom arm to the boom center section.
An agricultural vehicle comprising:
- a chassis;
- wheels supporting the chassis for moving the vehicle;
- an application system supported by the chassis and including a product tank storing a volume of agricultural product for delivery onto an agricultural field;
- an application boom configured to deliver the agricultural product to the agricultural field, the application boom including:
- a boom center section;
- and
- a first boom arm supported by the boom center section, the first boom arm including;
- a longitudinal composite tube with an end;
- a non-composite member coupled with the longitudinal composite tube at the end of the longitudinal composite tube;
- and
- a ferrule fastening the non-composite member to the longitudinal composite tube, the ferrule being disposed at the end of the longitudinal composite tube,
- wherein:
- the non-composite member further includes a ridge being contiguous with the end of the longitudinal composite tube;
- the ridge extends beyond an exterior surface of the longitudinal composite tube;
- and
- the ferrule includes a groove to receive a portion of the ridge of the non-composite member.
An agricultural vehicle comprising:
- a chassis;
- wheels supporting the chassis for moving the agricultural vehicle;
- an application system supported by the chassis and including a product tank storing a volume of agricultural product for delivery onto an agricultural field;
- an application boom configured to deliver the agricultural product to the agricultural field, the application boom including;
- a boom center section;
- a first boom arm and a second boom arm, both of which being supported by the boom center section, each of the first boom arm and second boom arm including, respectively;
- a truss system having a longitudinal carbon fiber tube with an end, the longitudinal carbon fiber tube having an inner cross section and an exterior surface, the inner cross section being an elliptical or oval shape;
- a cast metal member coupled with the longitudinal carbon fiber tube, the cast metal member including an exterior cross section being contiguous with the inner cross section of the longitudinal carbon fiber tube, the cast metal member further including a ridge extending beyond the exterior surface of the longitudinal carbon fiber tube and being contiguous with the end of the longitudinal carbon fiber tubed;
- and
- a metallic ferrule fastening the cast metal member to the longitudinal carbon fiber tube, the metallic ferrule being disposed at the end of the longitudinal composite tube and surrounding the end of the longitudinal carbon fiber tube, the metallic ferrule including a groove to receive a portion of the ridge of the cast metal member;
- and
- a lift arm arrangement connecting the application boom to the chassis and that is configured to raise and lower the application boom.
