Abstract

A monitoring system for an agricultural implement includes a sensor configured to output a sensor signal indicative of a position of at least one scraper of the agricultural implement relative to a surface of at least one respective disc. The at least one scraper is configured to engage the surface of the at least one respective disc to remove accumulated soil from the surface of the at least one respective disc. The monitoring system also includes a controller communicatively coupled to the sensor. The controller is configured to determine an amount of wear on the at least one scraper based on the position of the at least one scraper relative to the surface of the at least one respective disc, and the controller is configured to output a wear signal indicative of the amount of wear on the at least one scraper.

First claim

The invention claimed is:

1. A monitoring system for an agricultural implement, comprising:
a sensor configured to output a sensor signal indicative of a position of at least one scraper of the agricultural implement relative to a surface of at least one respective disc corresponding to an amount of wear on the at least one scraper due to contact between the at least one scraper and the surface of the at least one respective disc, wherein the at least one scraper is configured to engage the surface of the at least one respective disc to remove accumulated soil from the surface of the at least one respective disc; and
a controller comprising a memory and a processor, wherein the controller is communicatively coupled to the sensor, the controller is configured to determine the amount of wear on the at least one scraper based on the position of the at least one scraper relative to the surface of the at least one respective disc, and the controller is configured to output a wear signal indicative of the amount of wear on the at least one scraper.

2. The monitoring system of claim 1 , wherein the sensor is configured to couple to the at least one scraper.

3. The monitoring system of claim 2 , wherein the sensor comprises a linear variable differential transformer (LVDT).

4. The monitoring system of claim 1 , wherein the at least one scraper comprises a first inner scraper and a second inner scraper, the at least one respective disc comprises a first respective disc and a second respective disc, the first inner scraper is configured to engage the surface of the first respective disc, the second inner scraper is configured to engage the surface of the second respective disc, the sensor signal indicative of the position of the at least one scraper relative to the surface of the at least one respective disc is indicative of a distance between the first inner scraper and the second inner scraper, and the controller is configured to determine the amount of wear on the first inner scraper, the second inner scraper, or a combination thereof, based on the distance between the first inner scraper and the second inner scraper.

5. The monitoring system of claim 4 , wherein the sensor is configured to couple to the first inner scraper and to the second inner scraper.

6. The monitoring system of claim 1 , wherein the controller is configured to compare the amount of wear on the at least one scraper to a threshold amount of wear, and the controller is configured to output the wear signal only in response to determining that the amount of wear on the at least one scraper is greater than the threshold amount of wear.

7. The monitoring system of claim 1 , comprising an actuator configured to control a magnitude of force applied by the at least one scraper to the surface of the at least one respective disc, wherein the actuator is communicatively coupled to the controller, and the wear signal indicative of the amount of wear on the at least one scraper is indicative of instructions to control the magnitude of the force applied by the at least one scraper to the surface of the at least one respective disc.

8. A monitoring system for an agricultural implement, comprising:
a sensor configured to output a sensor signal indicative of a distance between a first inner scraper and a second inner scraper of the agricultural implement, wherein the first inner scraper is configured to engage a surface of a first respective disc to remove accumulated soil from the surface of the first respective disc, and the second inner scraper is configured to engage a surface of a second respective disc to remove accumulated soil from the surface of the second respective disc; and
a controller comprising a memory and a processor, wherein the controller is communicatively coupled to the sensor, the controller is configured to determine an amount of wear on the first inner scraper, the second inner scraper, or a combination thereof, based on the distance between the first inner scraper and the second inner scraper, and the controller is configured to output a wear signal indicative of the amount of wear.

9. The monitoring system of claim 8 , wherein the sensor is configured to couple to the first inner scraper and to the second inner scraper.

10. The monitoring system of claim 9 , wherein the sensor comprises a linear variable differential transformer (LVDT).

11. The monitoring system of claim 8 , wherein the controller is configured to compare the amount of wear to a threshold amount of wear, and the controller is configured to output the wear signal only in response to determining that the amount of wear is greater than the threshold amount of wear.

12. The monitoring system of claim 8 , comprising:
a first actuator configured to control a magnitude of force applied by the first inner scraper to the surface of the first respective disc, wherein the first actuator is communicatively coupled to the controller; and
a second actuator configured to control a magnitude of force applied by the second inner scraper to the surface of the second respective disc, wherein the second actuator is communicatively coupled to the controller;
wherein the wear signal is indicative of instructions to control the magnitude of the force applied by the first inner scraper to the surface of the first respective disc, to control the magnitude of the force applied by the second inner scraper to the surface of the second respective disc, or a combination thereof.
