Abstract

An electric adjusting apparatus for a row cleaner has a pair of upright posts connected by a pair of parallel linkages, an electric motor with a lead screw and a motor controller. One of the posts mounts on a fertilizing and/or planting apparatus and the row cleaner mounts on the other post. The electric motor moves the parallel linkages to move the row cleaner up and down without tilting. The motor controller controls the electric motor and displays the depth of the row cleaner.

Claims

1. An apparatus for adjusting the height of a row cleaner on a fertilizing and/or planting apparatus that is pulled by a tractor, comprising:

a generally upright first post connected to said fertilizing and/or planting apparatus,

a second post mounted on said row cleaner,

a first parallel linkage having an elongated upper link and a spaced, elongated lower link, said upper link pivotally mounting to said first post at one end and pivotally mounting to said second post at an end opposite said first post, said lower link pivotally mounting, below said upper link, to said first post at one end and pivotally mounting to said second post at an end opposite said first post, such that said first and second posts are parallel and said upper and lower links are parallel, said lower link including a downwardly projecting flange, and

a motor assembly having a motor, a lead screw and a lead screw nut, said motor connected to said first post, said lead screw projecting from said motor, and said lead screw nut threadedly engaging said lead screw and mounting on said flange,

whereby rotation of said motor moves said flange and thereby adjusts the height of said row cleaner without tilting.

2. The apparatus as set forth in claim 1 including a second parallel linkage spaced laterally from said first parallel linkage and having an elongated upper link and a spaced, elongated lower link, said upper link pivotally mounting to said first post at one end and pivotally mounting to said second post at an end opposite said first post, said lower link pivotally mounting, below said upper link, to said first post at one end and pivotally mounting to said second post at an end opposite said first post, such that said first and second posts are parallel and said upper and lower links are parallel.

3. The apparatus as set forth in claim 1 wherein said motor is an electric motor.

4. The apparatus as set forth in claim 1 including a controller connected to said motor.

5. The apparatus as set forth in claim 4 wherein said controller is in said tractor,

whereby an operator can adjust the height of said row cleaner while operating said tractor.

6. The apparatus as set forth in claim 4 wherein:

said motor assembly includes an encoder integrated with said motor and connected to said controller, and

said controller includes a display that displays the height of said row cleaner from converted signals from said encoder.

7. The apparatus as set forth in claim 1:

including a support member that mounts on and projects from said fertilizing and/or planting apparatus, and

wherein said first post mounts on said support member opposite said fertilizing and/or planting apparatus.

8. The apparatus as set forth in claim 7 wherein said motor assembly includes a mounting bracket that mounts on said support member, and said mounting bracket has a downwardly projecting yoke with said motor rotatably mounting on said yoke.

9. The apparatus as set forth in claim 1 wherein said motor is powered by said tractor.

10. An apparatus for adjusting the height of a row cleaner on a fertilizing and/or planting apparatus that is pulled by a tractor, comprising:

a support member that mounts on and projects from said fertilizing and/or planting apparatus

a generally upright first post mounted on said support member opposite said fertilizing and/or planting apparatus,

a second post mounted on said row cleaner,

a first parallel linkage having an elongated upper link and a spaced, elongated lower link, said upper link pivotally mounting to said first post at one end and pivotally mounting to said second post at an end opposite said first post, said lower link pivotally mounting, below said upper link, to said first post at one end and pivotally mounting to said second post at an end opposite said first post, such that said first and second posts are parallel and said upper and lower links are parallel, said lower link including a downwardly projecting flange,

a second parallel linkage spaced laterally from said first parallel linkage and having an elongated upper link and a spaced, elongated lower link, said upper link pivotally mounting to said first post at one end and pivotally mounting to said second post at an end opposite said first post, said lower link pivotally mounting, below said upper link, to said first post at one end and pivotally mounting to said second post at an end opposite said first post, such that said first and second posts are parallel and said upper and lower links are parallel,

a motor assembly having an electric motor, an encoder, a lead screw and a lead screw nut, said motor being mounted on said support member, said lead screw projecting from said motor, and said lead screw nut threadedly engaging said lead screw and mounting on said flange, and

a controller connected to said motor and said encoder,

whereby said controller rotates said motor to move said flange and thereby adjust the height of said row cleaner without tilting.

11. A system for adjusting the height of a plurality of row cleaners on a fertilizing and/or planting apparatus that is pulled by a tractor, comprising:

for each said row cleaner, apparatus for adjusting the height of said row cleaner including;

a generally upright first post connected to said fertilizing and/or planting apparatus,

a second post mounted on said row cleaner,

a first parallel linkage having an elongated upper link and a spaced, elongated lower link, said upper link pivotally mounting to said first post at one end and pivotally mounting to said second post at an end opposite said first post, said lower link pivotally mounting, below said upper link, to said first post at one end and pivotally mounting to said second post at an end opposite said first post, such that said first and second posts are parallel and said upper and lower links are parallel, said lower link including a downwardly projecting flange, and

a motor assembly having a motor, a lead screw and a lead screw nut, said motor connected to said first post, said lead screw projecting from said motor, and said lead screw nut threadedly engaging said lead screw and mounting on said flange, and

a controller connected to said motor on each said apparatus for adjusting the height of said row cleaner,

whereby said controller rotates said motors to move said flanges and thereby adjust the height of said row cleaners without tilting.

12. The system as set forth in claim 11 wherein said controller has a plurality of selection buttons that allow selection for adjustment any selected individual row cleaner and allow selection for adjustment all said row cleaners.

13. The system as set forth in claim 11 wherein each said apparatus for adjusting includes a second parallel linkage spaced laterally from said first parallel linkage and having an elongated upper link and a spaced, elongated lower link, said upper link pivotally mounting to said first post at one end and pivotally mounting to said second post at an end opposite said first post, said lower link pivotally mounting, below said upper link, to said first post at one end and pivotally mounting to said second post at an end opposite said first post, such that said first and second posts are parallel and said upper and lower links are parallel.

14. The system as set forth in claim 11 wherein said motor for each said apparatus for adjusting is an electric motor.

15. The system as set forth in claim 11 wherein said controller is in said tractor,

whereby an operator can adjust the height of said row cleaners while operating said tractor.

16. The system as set forth in claim 11 wherein:

said motor assembly for each said apparatus for adjusting includes an encoder integrated with said motor and connected to said controller, and

said controller includes a display that displays the height of said row cleaners from converted signals from said encoders.
