Abstract

A compaction and support apparatus for packing the ground immediately after tillage includes a frame and a wheel support gang movably mounted adjacent a rearward end of the frame. A plurality of tillers are supported in spaced relation from the frame, and a plurality of compaction and support wheels are rotatably mounted on the wheel support gang. Adjacent wheels are staggered longitudinally to track spaced apart substantially parallel paths on the ground. The path of each wheel is aligned behind one of the tillers mounted on the frame and the wheel is mounted on the wheel support gang so that the wheel substantially follows the contour of the ground while supporting the frame for transport and operation. The frame height is adjustable relative to the wheel support gang for controlling the extent of tiller penetration into the ground.

Claims

1. A compaction apparatus for packing the ground immediately after tillage, the apparatus comprising:

a frame having a plurality of tillers supported in spaced relation thereby;

a wheel support gang movably mounted on the frame adjacent a rearward end of the frame;

a plurality of compaction and support wheels, one of said wheels being provided per each and every tiller supported on said frame with the wheels being rotatably mounted on the wheel support gang parallel to each other and each wheel being longitudinally disposed behind its respective one of the tillers on the frame with adjacent wheels staggered longitudinally;

vertically movable means for mounting each wheel on the wheel support gang in such a manner that each wheel moves generally independently to substantially follow the contour of the ground while supporting the frame for transport and operation; and

frame height control means for adjusting the height of the frame relative to the wheel support gang and thus controlling the extent of tiller penetration into the ground.

2. The apparatus of claim 1 wherein the frame has hitch means vertically movably mounted on a forward end of the frame in such a manner that the height of the frame is adjustable relative to the hitch means.

3. The apparatus of claim 2 wherein the frame height control means adjusts the height of the frame relative to the wheel support gang.

4. The apparatus of claim 1 wherein the frame has a central portion and at least one wing portion pivotally mounted longitudinally to the central portion on a side of the central portion, and at least one wheel support gang being movably mounted adjacent a rearward end of each frame portion to provide support and compaction for each frame portion.

5. The apparatus of claim 4 wherein the central frame portion has hitch means vertically movably mounted on a forward end of the central frame portion in such a manner that the height of the frame is adjustable relative to the hitch means.

6. The apparatus of claim 5 wherein the frame height control means has means for varying the height of each frame portion relative to the wheel support gangs mounted thereon, the varying means being operably connected to simultaneously adjust the height of the frame portions.

7. The apparatus of claim 4 and further comprising:

contour following means for pivotally mounting each wheel support gang to its frame portion on a lateral axis relative to the frame portion.

8. The apparatus of claim 4 and further comprising:

means for pivotally mounting each wheel support gang to its frame portion on a longitudinal axis relative to the frame portion.

9. The apparatus of claim 1 and further comprising:

contour following means for pivotally mounting the wheel support gang to the frame on a lateral axis relative to the frame.

10. The apparatus of claim 1 and further comprising:

means for pivotally mounting the wheel support gang to the frame on a longitudinal axis relative to the frame.

11. The apparatus of claim 1, and further comprising:

hitch means adjacent a forward end of the frame for selectively securing the frame to a towing vehicle; and

means for moving a portion of hitch means vertically with respect to the forward end of the frame.

12. A compaction apparatus for packing the ground immediately after tillage, the apparatus comprising:

a frame having a plurality of tillers supported in spaced relation thereby;

a wheel support gang movably mounted on the frame adjacent a rearward end of the frame;

a plurality of compaction and support wheels, the wheels being rotatably mounted with respect to the wheel support gang parallel to each other and each wheel being disposed behind one of the tillers on the frame with adjacent wheels staggered longitudinally;

a plurality of walking beams pivotally mounted on the wheel support gang, two of the compaction and support wheels being rotatably mounted on opposite ends of each walking beam, and each walking beam being pivotally mounted to the wheel support gang at a point on the walking beam between the two wheels supported thereby in such a manner that each wheel substantially follows the contour of the ground while supporting the frame for transport and operation; and

frame height control means for adjusting the height of the frame relative to the wheel support gang and thus controlling the extent of tiller penetration into the ground.

13. The apparatus of claim 12, and further comprising:

hitch means adjacent a forward end of the frame for selectively securing the frame to a towing vehicle; and

means for moving a portion of hitch means vertically with respect to the forward end of the frame.

14. The apparatus of claim 12 wherein the frame height control means adjusts the height of the frame relative to the wheel support gang.

15. A compaction apparatus for packing the ground immediately after tillage, the apparatus comprising:

a frame having a plurality of tillers supported in spaced relation thereby, the frame having a central portion and at least one wing portion pivotally mounted longitudinally to the central portion on a side of the central portion;

at least one wheel support gang being movably mounted on each frame portion adjacent a rearward end of each said portion to provide support and compaction for each frame portion;

a plurality of compaction and support wheels, the wheels being rotatably mounted on each wheel support gang parallel to each other and each wheel being disposed behind one of the tillers on the frame with adjacent wheels staggered longitudinally;

a plurality of walking beams pivotally mounted on each wheel support gang, two of the compaction and support wheels being rotatably mounted on opposite ends of each walking beam, and each walking beam being pivotally mounted to its wheel support gang at a point on the walking beam between the two wheels supported thereby in such a manner that each wheel substantially follows the contour of the ground while supporting the frame for transport and operation; and

frame height control means for adjusting the height of the frame relative to the wheel support gang and thus controlling the extent of tiller penetration into the ground.

16. The apparatus of claim 15 wherein the central frame portion has hitch means vertically movably mounted on a forward end of the central frame portion in such a manner that the height of the frame is adjustable relative to the hitch means.

17. The apparatus of claim 16 wherein the frame height control means has means for varying the height of each frame portion relative to the wheel support gangs mounted thereon, the varying means being operably connected to simultaneously adjust the height of the frame portions.

18. The apparatus of claim 15, and further comprising:

hitch means adjacent a forward end of the frame for selectively securing the frame to a towing vehicle; and

means for moving a portion of hitch means vertically with respect to the forward end of the frame.

19. The apparatus of claim 15 and further comprising:

means for pivotally mounting each wheel support gang to its frame portion on a longitudinal axis relative to the frame portion.
