Abstract

A seeding machine includes a main frame and a row unit coupled to the main frame. The row unit has a row unit frame and a seed firmer coupled to the row unit frame. The seeding machine also includes a seed detection sensor coupled to the seed firmer. The seed detection sensor is configured to detect seed position within an open furrow.

Claims

1. A seeding machine comprising:

a main frame;

a row unit coupled to the main frame, the row unit having a row unit sub-frame and a furrow following device coupled to the row unit sub-frame; and

a seed detection sensor coupled to the furrow following device, wherein the seed detection sensor is an accelerometer configured to detect seed position within an open furrow.

2. The seeding machine of claim 1, further comprising a controller, wherein the seed detection sensor is configured to send one or more signals to the controller corresponding to detection of seeds, and wherein the controller is configured to determine the seed position based on the one or more signals.

3. The seeding machine of claim 2, wherein the one or more signals are acceleration pulses.

4. The seeding machine of claim 2, further comprising a display coupled to the controller, wherein the display is configured to display information regarding seed placement within a field.

5. The seeding machine of claim 2, wherein the furrow following device is a seed firmer, and wherein the controller is configured to issue a warning to an operator of at least one of an indication of seed firmer malfunction, an indication that the speed of the seeding machine is too high, or an indication that furrow characteristics may be unsuitable for planting, in response to measurement by the seed detection sensor of accelerations greater than a predefined level.

6. The seeding machine of claim 1, wherein the seed detection sensor is a first seed detection sensor, and wherein a second seed detection sensor is coupled to the row unit.

7. The seeding machine of claim 6, wherein the first seed detection sensor is a first type of seed detection sensor, and wherein the second seed detection sensor is a second, different type of seed detection sensor.

8. A seeding machine comprising:

a main frame;

a row unit coupled to the main frame, the row unit having a row unit sub-frame and a seed firmer coupled to the row unit sub-frame; and

an accelerometer coupled to the seed firmer, wherein the accelerometer is configured to detect seed position within an open furrow.

9. The seeding machine of claim 8, further comprising a controller, wherein the seed detection sensor is configured to send one or more signals to the controller corresponding to detection of seeds, and wherein the controller is configured to determine the seed position based on the one or more signals.

10. The seeding machine of claim 9, further comprising a display coupled to the controller, wherein the display is configured to display information regarding seed placement within a field.

11. The seeding machine of claim 9, wherein the controller is configured to issue a warning to an operator of at least one of an indication of a seed firmer malfunction, an indication that the speed of the seeding machine is too high, or an indication that furrow characteristics may be unsuitable for planting, in response to measurement by the seed detection sensor of accelerations greater than a predefined level.

12. The seeding machine of claim 8, wherein the seed detection sensor is a first seed detection sensor, and wherein a second seed detection sensor is coupled to the row unit.

13. The seeding machine of claim 12, wherein the first seed detection sensor is a first type of seed detection sensor, and wherein the second seed detection sensor is a second, different type of seed detection sensor.

14. The seeding machine of claim 8, wherein the row unit is a first row unit, and wherein a second row unit is coupled to the main frame.

15. A seeding machine comprising:

a main frame;

a row unit coupled to the main frame, the row unit having a row unit sub-frame and a seed firmer coupled to the row unit sub-frame;

a seed detection sensor coupled to the seed firmer, wherein the seed detection sensor is an accelerometer; and

a controller coupled to the seed detection sensor, wherein the controller is configured to determine seed position at least partially based on one or more signals received from the seed detection sensor, and wherein the controller is configured to issue a warning to an operator of a seed firmer malfunction in response to measurement by the seed detection sensor of an acceleration greater than a predefined level.

16. The seeding machine of claim 15, further comprising a display coupled to the controller, wherein the display is configured to display information regarding seed placement within a field.

17. A seeding machine comprising:

a main frame;

a row unit coupled to the main frame, the row unit having a row unit sub-frame and a seed firmer coupled to the row unit sub-frame, the seed firmer including a chamber, and a cover that covers that chamber; and

a seed detection sensor coupled to the seed firmer at least partially within the chamber, wherein the seed detection sensor is an accelerometer configured to detect seed position within an open furrow.

18. The seeding machine of claim 17, further comprising a controller, and at least one electrical conductor coupled to both the seed detection sensor and the controller.

19. The seeding machine of claim 17, further comprising a controller, wherein the seed detection sensor is configured to send a wireless signal or signals to the controller.
