Abstract

A mud scraper assembly includes a scraper blade mounted on the lower end of a scraper arm which in turn has a clamp at its upper end mounted on the sleeve of a depth gauge wheel support arm. No alteration of existing planter structure is required for adapting the mud scraper assembly to a Deere Max-Emerge planter and planters having generally the same structure. An adjustment screw is provided on the clamp for engaging the wheel support arm at a point remote to the shaft axis on which it is mounted to pivot the scraper arm into close proximity with the depth gauge wheels as needed.

Claims

1. A depth gauge wheel assembly comprising,

a support shaft on which a sleeve on one end of an arm is mounted, said arm having a depth gauge wheel mounted on its other end,

a mud scraper assembly including a clamp mounting means at one end connected to said sleeve, an arm extending from said clamp mounting means and including a scraper means positioned closely adjacent said wheel for removing mud on said wheel,

said clamp mounting means being U-shaped with spaced apart clamp elements extending from said clamp arm on opposite sides of said sleeve, and a bolt means interconnecting the free ends of said clamp elements, and

one of said clamp elements including a portion extending parallel to said wheel arm, an adjustment bolt being carried on said portion and positioned to engage said wheel arm at a point remote to the axial center of said shaft whereby pressure on said wheel arm by said adjustment bolt causes said clamp to rotate relative to said sleeve and allows said scraper to be closely positioned adjacent to said wheel.

2. The structure of claim 1 wherein said wheel includes an exterior peripheral surface and said scraper means is positioned to clean said peripheral surface.

3. The structure of claim 2 wherein said scraper assembly is connected to said depth gauge wheel assembly to move as an integral unit whereby the scraper means remains in a consistent relationship with said wheel peripheral surface.

4. The structure of claim 1 and seed groove cutting discs are mounted closely adjacent said depth wheel.

5. The structure of claim 4 and a pair of packer wheels are positioned rearwardly of said depth gauge wheel and said discs to close a seed groove formed by said cutting discs.

6. The structure of claim 5 and a seed tube is positioned to place seed in said seed groove.

7. The structure of claim 1 wherein said shaft includes a pair of depth gauge wheel assemblies in lateral spaced relationship and mud scraper assemblies on each wheel assembly, a pair of seed groove cutting discs positioned between said wheel assemblies, and a seed delivery tube positioned to place seed in a groove made by said discs.

8. A multiple row seed planter comprising,

a frame from which a transversely extending shaft is positioned for each row,

a pair of wheel support arms each having a sleeve on one end on each shaft with depth gauge wheels on their other free ends,

a pair of seed groove cutting discs positioned closely adjacent each pair of gauge wheels,

packer wheel means positioned behind said depth gauge wheels,

a seed delivery tube positioned to deliver seed into a seed groove,

a mud scraper assembly including a clamp mounting means at one end connected to each of said sleeves, an arm extending from said clamp mounting means and including a scraper means positioned closely adjacent said wheel for removing mud on said wheel,

said clamp mounting means being U-shaped with spaced apart clamp elements extending from said clamp arm on opposite sides of said sleeve, and a bolt means interconnecting the free ends of said clamp elements, and

one of said clamp elements including a portion extending parallel to said wheel arm, an adjustment bolt carried on said portion and positioned to engage said wheel arm at a point remote to the axial center of said shaft whereby pressure on said wheel arm by said adjustment bolt causes said clamp to rotate relative to said sleeve and allows said scraper to be closely positioned adjacent to said wheel.

9. A mud scraper assembly comprising,

an arm having a scraper means at one end and a mounting means at the other end adapted to engage a support shaft means for relative adjustment rotation about the shaft, and

an adjustment bolt on said mounting means offset from a lateral axis of said mounting means and positioned to engage a fixed portion of a depth gauge wheel support arm remotely of said shaft to closely position said scraper means next to the peripheral surface of a depth gauge wheel.

10. A multiple row seed planter comprising,

a frame from which a transversely extending shaft is positioned for each row,

a pair of wheel support arms each having a sleeve on one end on each shaft with depth gauge wheels on their other free ends,

a pair of seed groove cutting discs positioned closely adjacent each pair of gauge wheels,

packer wheel means positioned behind said depth gauge wheels,

a seed delivery tube positioned to deliver seed into a seed groove,

a mud scraper assembly including a clamp mounting means at one end connected to each of said sleeves, an arm extending from said clamp mounting means and including a scraper means positioned closely adjacent said wheel for removing mud on said wheel, and

said clamp mounting means being U-shaped with spaced apart clamp elements extending from said clamp arm on opposite sides of said sleeve, and a bolt means interconnecting the free ends of said clamp elements.

11. A mud scraper assembly comprising,

an arm having a scraper means at one end and a mounting means at the other end adapted to engage a support shaft means for relative adjustment rotation about the shaft, and

a stop means on said mounting means offset from a lateral axis of said mounting means and positioned to engage a fixed portion of a depth gauge wheel support arm remotely of said shaft to limit rotational movement of said scraper means away from the peripheral surface of a depth gauge wheel.

12. A depth gauge wheel assembly comprising,

a support shaft on which a sleeve on one end of an arm is mounted, said arm having a depth gauge wheel mounted on its other end,

a mud scraper assembly including a clamp mounting means at one end connected to each of said sleeves, an arm extending from said clamp mounting means and including a scraper means positioned closely adjacent said wheel for removing mud on said wheel,

said clamping mounting means being U-shaped with spaced apart clamp elements extending from said clamp arm on opposite sides of said sleeve, and a bolt means interconnecting the free ends of said clamp elements, and

one of said clamp elements including a portion extending parallel to said wheel arm, a stop means carried on said portion and positioned to engage said wheel arm at a point remote to the axial center of said shaft whereby pressure on said wheel arm by said stop means limits rotation of said clamp relative to said sleeve for maintaining said scraper closely positioned adjacent to said wheel.
