Abstract

An improved method of monitoring penetration of a planting unit into a ground surface comprising engaging a planting unit with a ground surface wherein the planting unit has a planting unit frame and the planting unit frame is cooperatively engaged with a support member by a planting frame and wherein the planting unit comprises, a seed trench opening assembly operable to create a seed trench in a ground surface, a depth regulating member having a vertical position relative to the seed trench opening assembly and monitoring penetration of the furrow forming structure into the ground surface.

Claims

1. An improved method of monitoring penetration of a planting unit into a ground surface comprising:

a. engaging a planting unit with a ground surface wherein said planting unit has a planting unit frame and said planting unit frame is cooperatively engaged with a support member wherein the planting unit comprises;

i. a seed trench opening assembly operable to create a seed trench in a ground surface;

ii. a seed delivery assembly delivering seeds into the seed trench;

iii. a seed trench closing assembly operable to close the seed trench;

iv. a depth regulating member having a vertical position relative to said seed trench opening assembly, wherein said depth regulating member experiences an actual vertical force that controls ground surface engagement;

v. a pivoting arm assembly connecting said depth regulating member to said planting unit frame; and

vi. a stop means mechanically engaging a portion of said pivoting arm assembly for defining a limit for vertical motion of said depth regulating member in the direction substantially opposite said ground surface;

b. applying down pressure to said planting unit to ensure penetration of said planting unit into said ground surface;

c. allowing the planting unit to respond to terrain and elevation changes in said ground surface while maintaining a desired depth of seed placement during travel across said ground surface;

d. controlling the down pressure applied to the planting unit; and

,

e. monitoring penetration of said furrow forming means into said ground surface wherein the depth monitoring means indicates engagement of said arm assembly with said stop means.

2. The improved method of monitoring penetration of said planting unit into said ground surface as set forth in claim 1 further comprising transmitting engagement information of said arm assembly with said stop means through a transmission means to a display means.

3. The improved method of monitoring penetration of said planting unit into said ground surface as set forth in claim 2 wherein said transmission means is in communication with a data collection means.

4. The improved method of monitoring penetration of said planting unit into said ground surface as set forth in claim 3 wherein said data collection means is a computer.

5. The improved method of monitoring penetration of said planting unit into said ground surface as set forth in claim 4 wherein said computer has an operator interface for communication with a planting unit assembly operator.

6. The improved method of monitoring penetration of said planting unit into said ground surface as set forth in claim 5 wherein said computer is integrated into a planter monitor.

7. The improved method of monitoring penetration of said planting unit into said ground surface as set forth in claim 1 wherein said depth monitoring means indicates penetration of said furrow forming means into said ground surface through indication and comparison of the selected vertical difference between said depth regulation means and said furrow forming means with the measured vertical difference between said depth regulation means and said furrow forming means.

8. The improved method of monitoring penetration of said planting unit into said ground surface as set forth in claim 1 wherein said depth monitoring means has an indication means selected from the group consisting of mechanical devices, electro-mechanical devices, electro-photo devices and combinations thereof.

9. The improved method of monitoring penetration of said planting unit into said ground surface as set forth in claim 1 further comprising adjusting the down pressure applied to the planting unit through a supplemental down pressure means for controlling the down pressure to said planting unit.

10. An improved method of monitoring penetration of a planting unit into a ground surface comprising:

a. engaging a planting unit with a ground surface wherein said planting unit has a planting unit frame and said planting unit frame is cooperatively engaged with a support member wherein the planting unit comprises;

i. a seed trench opening assembly operable to create a seed trench in a ground surface;

ii. a seed delivery assembly delivering seeds into the seed trench;

iii. a seed trench closing assembly operable to close the seed trench;

iv. a depth regulating member having a vertical position relative to said seed trench opening assembly, wherein said depth regulating member experiences an actual vertical force that controls ground surface engagement;

v. a pivoting arm assembly connecting said depth regulating member to said planting unit frame; and

vi. a stop means mechanically engaging a portion of said pivoting arm assembly for defining a limit for vertical motion of said depth regulating member in the direction substantially opposite said ground surface;

b. applying down pressure to said planting unit to ensure penetration of said planting unit into said ground surface;

c. allowing the planting unit to respond to terrain and elevation changes in said ground surface while maintaining a desired depth of seed placement during travel across said ground surface;

d. controlling the down pressure applied to the planting unit;

e. monitoring penetration of said furrow forming means into said ground surface; and

f. indicating engagement of said arm assembly with said stop means for detecting presence or absence of furrow forming means penetration into said ground surface.

11. The improved method of monitoring penetration of said planting unit into said ground surface as set forth in claim 10 further comprising transmitting engagement information of said arm assembly with said stop means through a transmission means to a display means.

12. The improved method of monitoring penetration of said planting unit into said ground surface as set forth in claim 11 wherein said transmission means is in communication with a data collection means.

13. The improved method of monitoring penetration of said planting unit into said ground surface as set forth in claim 12 wherein said data collection means is a computer.

14. The improved method of monitoring penetration of said planting unit into said ground surface as set forth in claim 13 wherein said computer has an operator interface for communication with a planting unit assembly operator.

15. The improved method of monitoring penetration of said planting unit into said ground surface as set forth in claim 14 wherein said computer is integrated into a planter monitor.

16. The improved method of monitoring penetration of said planting unit into said ground surface as set forth in claim 10 wherein penetration of said ground surface by said furrow forming means is through indication and comparison of the selected vertical difference between said depth regulation means and said furrow forming means with the measured vertical difference between said depth regulation means and said furrow forming means.

17. The improved method of monitoring penetration of said planting unit into said ground surface as set forth in claim 10 wherein the means of indication of engagement of said arm assembly with said stop means for detecting presence or absence of furrow forming means penetration into said ground surface is selected from the group consisting of mechanical devices, electro-mechanical devices, electro-photo devices and combinations thereof.

18. The improved method of monitoring penetration of said planting unit into said ground surface as set forth in claim 10 further comprising adjusting the down pressure applied to the planting unit through a supplemental down pressure means for controlling the down pressure to said planting unit.
