View Patent ↗A harvesting attachment for a harvesting machine includes a frame, and the frame includes an outer wall which defines a cavity in which at least one strut is arranged.
1. A harvesting attachment for a harvesting machine comprising an L-shaped frame, the frame including an outer wall, the outer wall including a front wall, a rear wall, and two side walls, the frame including a holding fixture characterized by an opening in the L-shaped frame, the holding fixture mounting the rear wall to the harvesting machine, wherein a cavity is defined by the outer wall, wherein at least one strut is arranged in the cavity including at least one cross strut connecting the front and rear walls and extending substantially horizontal, and wherein the frame is mounted to a front side of the harvesting machine.
2. The harvesting attachment according to claim 1 , wherein a strut system is arranged in the cavity including the at least one strut.
3. The harvesting attachment according to claim 1 , wherein the frame includes at least one tubular through opening which extends parallel to the front and rear walls of the outer wall.
4. The harvesting attachment according to claim 1 , wherein a plurality of struts are arranged in the cavity.
5. The harvesting attachment according to claim 2 , wherein the frame is made of cast light metal.
6. The harvesting attachment according to claim 5 , wherein at least one sheet is mounted on the outer wall, which covers a recess in the outer wall.
7. The harvesting attachment according to claim 2 , wherein the frame is manufactured by a light-metal welding method.
8. The harvesting attachment according to claim 2 , wherein the frame is made of aluminum.
9. The harvesting attachment according to claim 2 , wherein the frame is made of plastics.
10. The harvesting attachment according to claim 1 , wherein the outer wall has a wall thickness of 4 mm to 6 mm.
11. A harvesting attachment for a harvesting machine comprising:
an angular L-shaped frame, wherein the frame includes an outer wall including a front wall, a rear wall, and two side walls, the outer wall defining a cavity, at least one tubular through opening extending parallel to the front and rear walls; and
a strut system including at least two struts, said at least two struts comprising at least one cross strut which connects the front and rear walls and extends substantially horizontal.
12. The harvesting attachment according to claim 11 , wherein at least one strut of the strut system includes at least one recess.
13. The harvesting attachment according to claim 12 , wherein the frame includes segments which are connectable or connected with each other.
14. The harvesting attachment according to claim 13 , wherein at least one sheet is mounted on the outer wall, which covers a recess in the outer wall.
15. The harvesting attachment according to claim 13 , wherein the outer wall has a wall thickness of 4 mm to 6 mm.
16. A harvesting attachment for a harvesting machine comprising:
a cutting unit;
an angular L-shaped frame holding the cutting unit, wherein the frame includes an outer wall which defines a cavity, the outer wall including a front wall, a rear wall, and two side walls, the frame including at least one tubular through opening which extends parallel to the front and rear walls; and
a strut system arranged in the cavity including a plurality of struts, the plurality of struts including at least one cross strut connecting the front and rear walls and extending substantially horizontal, the struts including at least one recess.
17. The harvesting attachment according to claim 1 , further comprising a cutting unit held by the L-shaped frame.
