Abstract
A farm machine includes a frame, at least one rotor mounted on the frame, and a tapered flexible skirt for moving products that are on the ground mounted on the rotor. The tapered flexible skirt has close to its outer edge a zone the thickness of which is greater than the thickness of the remaining part of the tapered flexible skirt. The zone is an integral part of the tapered flexible skirt and extends without interruption over the entire periphery of the tapered flexible skirt.
Claims10
A farm machine comprising:
- (a) a frame;
- (b) at least one rotor mounted on said frame;
- and
- (c) a resilient flexible skirt at least generally in the shape of a hollow truncated cone for moving products that are on the ground mounted on said at least one rotor, said flexible skirt comprising a first zone and a second zone, said first zone:
- (i) having a thickness which is greater than the thickness of said second zone;
- (ii) being integrally formed as a part of said flexible skirt;
- (iii) extending without interruption over the entire periphery of said flexible skirt;
- (iv) extending to the outside edge of said flexible skirt;
- and
- (v) projecting downwardly beyond said second zone on the lower side of said flexible skirt.
A machine as recited in claim 5 wherein said first zone is connected to said second zone by an inclined part.
A resilient flexible skirt for farm machines, said flexible skirt being designed to move products that are on the ground, said flexible skirt comprising ribs extending upwardly from the surface and having a scalloped periphery, said skirt including a first zone and a second zone, said first zone:
- (a) having a thickness which is greater than the thickness of said second zone;
- (b) being integrally formed as a part of said flexible skirt;
- (c) extending without interruption over the entire periphery of said flexible skirt;
- (d) extending to the outside edge of said flexible skirt;
- and
- (e) projecting downwardly beyond said second zone on the lower side of said flexible skirt.
