Abstract

A seed drill includes a conventional single or double disc blade soil opener for creating seed trenches for the deposition of seeds by a seeder. A scraper/soil firming assembly is attached to the outside of each disc blade axle. The scraper/soil firming assembly includes a bracket for mounting a scraper/soil firming blade and a locking plate for locking the mounting bracket and blade at a selected angle relative to the disc blade axle. The scraper/soil firming blade is a flat bar extending downward and rearward from the respective disc blade and positioned alongside the disc blade and to act both as a blade scraper and as a soil firmer.

Claims

1. A seed drill comprising:

a. a soil opener including a first soil opening disc blade rotatably attached to a first axle, said first axle and said first disc blade being oriented such that said first disc blade is angled across a path of travel of said seed drill so that said first disc blade opens a seed trench along said path of travel;

b. a first scraping/soil blow-out prevention assembly attached via said first axle of said soil opener, said first scraping/soil blow-out prevention assembly including a blade, said blade being sized and positioned such that it simultaneously;

i. scrapes an outside surface of said first disc blade as it rotates; and

ii. prevents soil blow-out alongside the outside of said first disc blade.

5. A seed drill as in claim 1, and wherein:

a. said soil opener includes a second soil opening disc blade rotatably attached to a second axle, said second axle and said second disc blade being oriented such that said second blade is angled across said path of travel of said seed drill in a direction opposite to said first disc blade such that front surfaces of said first and second disc blades converge toward each other, said first and second disc blade, together, opening said seed trench along said path of travel; and

b. a second scraping/soil blow-out prevention assembly attached via said second axle of said soil opener, said second scraping/soil blow-out prevention assembly including a second blade, said second blade being sized and positioned such that it simultaneously;

i. scrapes an outside surface of said second disc blade as it rotates; and

ii. prevents soil blow-out alongside of said second disc blade.

6. A seed drill as in claim 5, wherein each of said first and second scraper/soil blow-out prevention assemblies further comprises:

a. a blade mounting bracket with first and second horizontal apertures therethrough, said first aperture accommodating a respective axle and said second aperture being an arcuate slot;

b. a locking plate with first and second bores therethrough, said first bore accommodating a head of said respective axle to fix said locking plate relative to said axle, said second bore being aligned with said arcuate slot in said mounting bracket; and

c. locking means extending through said second bore and said arcuate slot for locking said mounting bracket at a selected angle relative to said locking plate.

7. A seed drill as in claim 6, wherein each said mounting bracket also includes a mounting surface for mounting the respective blade in a position alongside said respective disc blade.

8. A seed drill as in claim 6, wherein each said blade is a flat plate of UHMW plastic.

2. A seed drill comprising:

a. a soil opener including a soil opening disc blade rotatably attached to an axle, said axle and said disc blade being oriented such that said disc blade is angled across a path of travel of said seed drill so that said disc blade opens a seed trench along said path of travel;

b. a scraping/soil blow-out prevention assembly attached via said axle of said soil opener, said scraping/soil blow-out prevention assembly including;

i. a blade;

ii. a blade mounting bracket with first and second horizontal apertures therethrough, said first aperture accommodating said axle and said second aperture being an arcuate slot;

iii. a locking plate with first and second bores therethrough, said first bore accommodating a head of said axle to fix said locking plate relative to said axle, said second bore being aligned with said arcuate slot in said mounting bracket; and

iv. locking means extending through said second bore and said arcuate slot for locking said mounting bracket at a selected angle relative to said locking plate.

3. A seed drill as in claim 2, wherein said mounting bracket also includes a mounting surface for mounting said blade in a position alongside said disc blade.

4. A seed drill as in claim 2, wherein said blade comprises UHMW plastic.

9. A scraper/soil blow-out prevention attachment for a seed drill, said seed drill including a soil opener including a first soil opening disc blade rotatably attached to a first axle, said first axle and said first disc blade being oriented such that said first disc blade is angled across a path of travel of said seed drill so that said first disc blade opens a seed trench along said path of travel, said scraper/soil blow-out prevention attachment comprising:

a. a first scraping/soil blow-out prevention assembly attachable via the first axle of said soil opener, said first scraping/soil blow-out prevention assembly including a blade, said blade being sized and positioned such that, when said first scraping/soil blow-out prevention assembly is attached to said seed drill, said blade simultaneously;

i. scrapes an outside surface of said first disc blade as it rotates; and

ii. prevents soil blow-out alongside the outside of said first disc blade.

10. A scraper/soil blow-out prevention attachment as in claim 9, wherein said first scraper/soil blow-out prevention assembly further comprises:

a. a blade mounting bracket with first and second horizontal apertures therethrough, said first aperture accommodating said first axle and said second aperture being an arcuate slot;

b. a locking plate with first and second bores therethrough, said first bore accommodating a head of said first axle to fix said locking plate relative to said first axle, said second bore being aligned with said arcuate slot in said mounting bracket; and

c. locking means extending through said second bore and said arcuate slot for locking said mounting bracket at a selected angle relative to said locking plate.

11. A scraper/soil blow-out prevention attachment as in claim 10, wherein said mounting bracket also includes a mounting surface for mounting said blade in a position alongside the outside of said first disc blade.

12. A scraper/soil blow-out prevention attachment as in claim 10, wherein said blade comprises UHMW plastic.

13. A scraper/soil blow-out prevention attachment as in claim 9, and wherein said soil opener includes a second soil opening disc blade rotatably attached to a second axle, said second axle and said second disc blade being oriented such that said second blade is angled across said path of travel of said seed drill in a direction opposite to said first disc blade such that front surfaces of said first and second disc blades converge toward each other, said first and second disc blade, together, opening said seed trench along said path of travel, said scraper/soil blow-out prevention attachment further comprising:

a. a second scraping/soil blow-out prevention assembly attached via said second axle of said soil opener, said second scraping/soil blow-out prevention assembly including a second blade, said second blade being sized and positioned such that it simultaneously;

i. scrapes an outside surface of said second disc blade as it rotates; and

ii. prevents soil blow-out alongside the outside of said second disc blade.

14. A scraper/soil blow-out prevention attachment as in claim 13, wherein each of said first and second scraper/soil blow-out prevention assemblies further comprises:
