Abstract

Abstract A harvesting device comprising a platform with rotary mowing devices along its forward edge arranged to sling the material upwardly and rearwardly onto an upwardly and rearwardly sloping platform for delivery of the crops to a pair of conditioning rollers, and a reel cooperating with the mowing devices which functions to feed the material prior to cutting into the mowing devices and after the material is cut sweeping the cut material off the mowing devices and controlling the flow of the material into the hay conditioning rollers.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 222 words
In a mower conditioner, an ambulatory frame, a stationary platform thereon having front and rear edges and sloping upwardly and rearwardly from the front edge to the rear edge, a pair of cooperative substantially horizontally disposed crop conditioning rollers mounted on the frame adjacent to said rear edge of the platform, mowing means mounted on the platform adjacent to its forward edge and comprising a plurality of cutters each having a disk mounted for rotation about an upright axis and each presenting an unobstructed upper crop-receiving surface, knife blades mounted in each disk and projective beyond the periphery thereof, said disks disposed in a substantially common plane, said cutters arranged in cooperative pairs rotating in opposite directions toward each other forwardly of the platform and effective to cut the crops and discharge them onto the respective disks, said disks sloping upwardly and rearwardly and rotating at high speeds and serving as conveying means for slinging the cut crops rearwardly and upwardly therefrom onto the platform, and a reel serving as supplementary conveying means mounted from the frame for rotation about a generally horizontal axis above the cutters and having peripheral fingers operative to sweep residual cut material from the rear portions of the disks and the platform and move the crops upwardly and rearwardly over the platform directly into the conditioning rollers.
Claim 2
Dependent Claim 222 words
In a mower conditioner, an ambulatory frame, a stationary platform thereon having front and rear edges and sloping upwardly and rearwardly from the front edge to the rear edge, a pair of cooperative substantially horizontally disposed crop conditioning rollers mounted on the frame adjacent to said rear edge of the platform, mowing means mounted on the platform adjacent to its forward edge and comprising a plurality of cutters each having a disk mounted for rotation about an upright axis and each presenting an unobstructed upper crop-receiving surface, knife blades mounted in each disk and projective beyond the periphery thereof, said disks disposed in a substantially common plane, said cutters arranged in cooperative pairs rotating in opposite directions toward each other forwardly of the platform and effective to cut the crops and discharge them onto the respective disks, said disks sloping upwardly and rearwardly and rotating at high speeds and serving as conveying means for slinging the cut crops rearwardly and upwardly therefrom onto the platform, and a reel serving as supplementary conveying means mounted from the frame for rotation about a generally horizontal axis above the cutters and having peripheral fingers operative to sweep residual cut material from the rear portions of the disks and the platform and move the crops upwardly and rearwardly over the platform directly into the conditioning rollers.
Claim 3
Dependent Claim 26 words
The invention according to claim 1, and said disks having upwardly convexed upper areas operative to inhibit material from climbing thereover as the material is cut.
Claim 4
Dependent Claim 63 words
The invention according to claim 1 and said reel comprising a series of cammed bars and said fingers mounted thereon, and said bars positioning said fingers essentially vertically over the disks and having a sweep over said disks downwardly behind the axes of rotation thereof and providing an obstruction to the movement of material from the rear toward the front of the disks.
Claim 5
Dependent Claim 31 words
The invention according to claim 3 and said bars positioning the fingers tangentially to the upper of said rollers at the discharge region of the reel with respect to the rollers.
Claim 6
Dependent Claim 52 words
The invention according to claim 1 and a housing structure mounted under said platform adjacent to its forward edge, and each cutter having a shaft defining its axis of rotation, said shaft extending below the disk thereof into the housing, and means enclosed in the housing for driving the cutters as aforesaid.
Claim 7
Dependent Claim 25 words
The invention according to claim 1 and the knife blades swingably mounted on respective disks and projecting forwardly of the forward end of the platform.
Claim 8
Dependent Claim 58 words
The invention according to claim 1 and said rollers comprising a lower roller and an upper roller disposed ahead of the lower roller and developing a downwardly facing nip, and said nip disposed above the plane of said platform and said reel fingers having a sweep path converging with the disks rearwardly of the axis of rotation thereof.
Claim 9
Dependent Claim 26 words
The invention according to claim 1 and said disks disposed intermediate the blades and the peripheral sweep of said fingers at elevations adjacent to the ground.
Claim 10
Dependent Claim 43 words
The invention according to claim 1 and said disks being domE-like and operative to converge the material therebetween, and said fingers disposed in planes intercepting the peripheries of said disks along chordal planes disposed rearwardly of the axes of rotation of said disks.
